Title: Geometrically Organized Mechanics: From Material Properties to Programmable Mechanical Behaviour

Plenary talk

Prof. Dr. Per Arvid Lothman

Euro-FH University of Applied Sciences Hamburg, Germany

Abstract

Mechanical behaviour is conventionally understood primarily through material composition, constitutive properties, geometry, and loading conditions. Recent developments in architected materials, mechanical metamaterials, origami engineering, tensegrity, and adaptive structures, however, demonstrate that mechanical functionality can also depend critically on how geometric relations and constraints are organized within a system. 

This contribution introduces Geometrically Organized Mechanics (GOM) as a framework for examining systems in which geometry functions not merely as shape or boundary condition but as an active mechanical resource. The central proposition is that geometric relations can constrain and couple the possibilities of individual components in ways that generate coordinated system-level behavior.

Origami and tensegrity provide two complementary examples. In origami-based systems, fold geometry and compatibility conditions organize motion by restricting otherwise independent degrees of freedom and establishing coordinated deformation pathways. In tensegrity systems, connectivity and prestress organize tensile and compressive interactions into compatible states of self-stress, producing stability through distributed relations rather than through conventional continuous load paths. These examples illustrate how geometry can organize both motion and force.

The framework can be extended toward mechanical metamaterials, multistable structures, programmable materials, and adaptive systems, where geometric organization structures not only mechanical states but also the transitions between them. Such systems can exhibit tunable stiffness, controlled deformation, reconfiguration, multistability, and programmable response.

Geometrically Organized Mechanics therefore suggests a broader perspective for materials science: mechanical functionality depends not only on what a material or structure is made of, but also on how its elements, constraints, and accessible states are organized. This perspective may provide a conceptual basis for designing increasingly programmable mechanical
materials and architectures.

Title: Stimulated Luminescence of Novel Oxides Obtained by Solution Combustion Synthesis

Plenary talk

Prof. Dr. Victor Ramon Orante Barron

University of Sonora, Mexico

Abstract

Solution combustion synthesis (SCS), also known as self-propagating high-temperature synthesis, is a technique which makes use of highly exothermic redox chemical reactions between metals and non-metals to produce a number of technologically useful oxides and non-oxides. Inorganic oxides were obtained by SCS carrying out a reaction involving metallic nitrates acting as oxidizers, and amino compounds as reducing agents. The combustion was accomplished at 500 ºC and the powder samples obtained were annealed at 900 ºC during 2 h in air, in order to remove residual reagents and improve the crystal structure of the samples. Results on the thermoluminescence (TL), obtained after different intervals of dose exposure, photoluminescence (PL), as well as the structural characterization of different annealed samples of novel oxides obtained by SCS, will be presented to show the most recent progress proposing these materials for luminescence dosimetry applications at Universidad de Sonora, making a collaborative effort with the University of South Africa (UNISA) research group.

Title: Nature-Inspired Intelligence or AI for Sustainable Materials Discovery?

Keynote Talk

Abstract

Contemporary nature-inspired research draws on biological structures and processes to develop advanced materials with enhanced functionality and sustainability. Inspired by systems such as bone architectures, cellular networks, and adaptive ecosystems, researchers increasingly combine biomimetic principles with artificial intelligence (AI) to accelerate materials discovery and design.

AI is transforming materials science through its ability to analyze complex datasets, model multiscale phenomena, and optimize material architectures. These capabilities support the development of lightweight, high-performance porous and lattice structures, often manufactured using advanced techniques such as additive manufacturing. Such approaches can improve mechanical efficiency while reducing material consumption and environmental impact. Similarly, the emergence of bio-based materials and deep eutectic solvents demonstrates how nature continues to inspire sustainable innovation in chemistry and materials processing.

Beyond materials development, AI offers powerful tools for addressing environmental challenges, including pollution control, carbon capture, and ecosystem monitoring. However, the growing use of AI also raises concerns related to energy consumption, resource use, ethical issues, and unforeseen technological consequences. These challenges highlight the importance of establishing clear guidelines for the responsible development and application of AI within a sustainability framework.

In the spirit of a renewed Humanitas, scientific and technological progress should be guided by wisdom, responsibility, and respect for the natural world. The convergence of AI and nature-inspired design encourages a balanced approach in which innovation learns from, rather than dominates, living systems. By integrating AI, biomimicry, and ethical stewardship, materials research can contribute to a more sustainable future for both humanity and the environment.

Title: Calcium Carbide Residue as a Sustainable Binder for Eco-Friendly Construction Materials

Plenary talk

Prof. Dr. Buruiana Daniela Laura

Dunarea de Jos University of Galati, Romania

Abstract

This study investigates the valorization of calcium carbide residue, an industrial by product rich in calcium hydroxide, as a low-carbon binder for sustainable construction materials. Calcium carbide residue was incorporated as a partial cement replacement in mortars and as a main component in unburned blocks cured through accelerated carbonation. The materials were evaluated in terms of mechanical performance, physical properties, environmental impact, and leaching behavior. The results showed that mortars containing 10-20% calcium carbide residue achieved adequate compressive strength for non-structural applications, while carbonated blocks exhibited significant strength improvement due to calcium carbonate formation. The incorporation of calcium carbide residue reduced the carbon footprint and met environmental safety requirements. These findings demonstrate that calcium carbide residue represents a promising secondary raw material supporting circular economy principles and the development of low-carbon construction materials.

Title: Surace chemistry strategies for development of acoustic wave biosensors for detection of a cancer biomarker

Plenary talk

Prof. Michael Thompson

University of Toronto, Canada

Abstract

Biosensors have significant potential to revolutionize diagnostics in centralized clinical laboratories while expanding opportunities for rapid and accessible point-of-care testing. Acoustic wave biosensors offer label-free, sensitive, and real-time monitoring of biomolecular interactions that can be applied towards analyte detection in complex biofluids. However, achieving excellent bioanalytical performance in complex matrices requires antifouling surface chemistry that minimizes nonspecific adsorption and enables analyte recognition through biorecognition probes. Antifouling is particularly crucial for detecting small biomarkers present at low concentrations in complex biofluids. Among these biomarkers, lysophosphatidic acid (LPA) is a small phospholipid associated with the onset and progression of ovarian cancer. Since ovarian cancer is commonly diagnosed in advanced stages when survival rate is poor, early diagnosis is critical. Existing blood tests suffer from limited sensitivity and specificity, highlighting the urgent need for an effective ovarian cancer screening test.

This lecture presents acoustic wave biosensors for the detection of LPA in serum with the electromagnetic piezoelectric acoustic sensor (EMPAS) and the thickness-shear mode (TSM)

sensor. Antifouling molecules based on monoethylene glycol were functionalized on the iii biosensing surfaces of EMPAS and TSM, providing bioconjugation capability for the

immobilization of the gelsolin-actin probe. The combination of antifouling chemistry and gelsolinactin enabled sensitive detection of LPA in undiluted human serum, reaching limits of detection of 1.07 and 0.70 μM with EMPAS and TSM, respectively. The biorecognition probe, gelsolin-actin, is a protein complex that enables label-free and indirect detection of LPA through LPA-induced dissociation of the complex. Molecular modeling revealed that the amphipathic nature of LPA destabilizes the complex through insertion of its hydrophobic tail into actin and interactions between its negatively charged headgroup with gelsolin. In addition to the developed acoustic wave biosensors for LPA, novel antifouling thiols were applied in aptasensors targeting penicillin and bacteria in human serum and whole milk, respectively. Furthermore, phosphonic acid surface functionalization was explored as an alternative to silanization of hydroxylated surfaces, where an octadecylphosphonic acid-based biosensor was developed for monitoring bacterial contamination in milk. Overall, this thesis demonstrates the capability of antifouling biosensors to achieve sensitive detection in complex biofluids for ovarian cancer diagnosis and food quality monitoring.

Title: From Nanomaterial Properties to Food-Quality Decisions: Smart Sensing Across the Cold Chain

Invited talk

Ivanov Andrei

Dunarea de Jos University of Galati, Romania

Abstract

Food quality continuously transforms throughout the process of production, transport, storage, sales and consumer use. Despite that, decisions are often based on expiry dates or lab analyses performed at selected moments. This paper looks at how nanostructured materials could convert biological and physicochemical changes in food quality into immediate, understandable signals to allow for intelligent monitoring of food quality. The issue is examined along the path from materials to decision: nanomaterials, targets, signal transduction, packaging and decision making by producers, sellers and consumers.

Metal and metal oxide nanoparticles, magnetic nanostructures, graphene and carbon nanotubes, quantum and carbon dots, and functional polymers have high surface-to-volume ratio, tunable optical and electrical properties, and functionalization opportunities. These features ensure colorimetric, fluorescent, electrochemical, chemiresistive and magnetic detection of spoilage metabolites and volatiles, foodborne pathogens, contaminants, adulterants, and failures in temperature and/or package integrity. The corresponding platforms comprise indicator labels and films, non-contact headspace sensors, paper-based tests, printed electrodes, electronic-nose arrays, and smart-phone or RFID/NFC-readable tags. In addition to single-point analysis, such sensors allow for distributed or continuous monitoring and earlier interventions.

The key benefits analytical sensitivity, fast response, portability, small sample size, and capability to combine sensing with antimicrobial or barrier properties are evaluated in regard to the requirements for practical applications. The problem of matrix interference, selectivity, humidity and temperature stability, reproducibility, nanoparticle migration, toxicological assessment, calibration, scaling-up, data governance, and regulatory approval become crucial.

This paper proposes materials centered approach to choosing appropriate nanomaterials, transducers and packaging to address particular matrices and monitoring tasks. Such approach allows to turn packaging into an information-generating interface.

Title: Sensor-Based Identification and Monitoring System for Secure Documents Containing Magnetic Microwires

Invited talk

Cătălin Aramă

Dunarea de Jos University of Galati, Romania

Abstract

The increasing need for enhanced protection and traceability of special-regime documents requires the integration of functional security materials with advanced detection and monitoring technologies. This study proposes a sensor-based system for the individual identification and monitoring of documents manufactured using a previously patented secure paper technology containing embedded magnetic microwires. The secure paper is considered in the present study as the functional material enabling magnetic detection, while the novelty of the proposed approach lies in the design and integration of dedicated sensors and detection units capable of recognizing and monitoring secured sheets throughout a controlled perimeter. Specialized sensors are proposed for installation on printing, copying, and document-destruction equipment in order to detect the magnetic signature associated with the secured paper and to control the processing of documents within the protected area. In addition, electromagnetic detection systems positioned at perimeter access points are integrated into the monitoring architecture to identify and track the movement of secured documents entering or leaving the controlled space. The combined use of equipment-mounted sensors, perimeter detection units, and a centralized monitoring system provides a framework for individual document identification, controlled circulation, and enhanced traceability. The proposed concept therefore extends the practical functionality of an existing magnetic-microwire-based secure paper technology through the development of a dedicated sensor architecture for active detection and monitoring. The approach highlights the potential of combining magnetic functional materials with sensor technologies to improve the physical security, traceability, and controlled management of high-security documents.

Abstract

The construction industry is a major consumer of natural resources and a significant contributor to global CO2 emissions, highlighting the need for more sustainable construction materials. Industrial waste valorization offers an effective approach to reducing virgin resource consumption, waste disposal, and the environmental impact of construction. This review examines the use of industrial waste as secondary raw materials, focusing on supplementary cementitious materials, alkali-activated binders and geopolymers, recycled aggregates, and waste-derived reinforcing materials. These solutions can reduce clinker consumption and associated CO2 emissions while maintaining or improving selected mechanical and durability properties. Their large-scale application remains limited by waste variability, potential contaminant leaching, processing requirements, long-term performance, and regulatory barriers. Industrial waste valorization represents a promising strategy for advancing circular and low-carbon construction.

Title: Next-Generation Kevlar-Based Ballistic Protection through Advanced Surface Modification

Invited talk

Georgiana Ghisman (Alexe)

Dunarea de Jos University of Galati, Romania

Abstract

The increasing demand for lightweight and efficient ballistic protection systems has intensified research into advanced strategies for improving the performance of high-strength fiber-based materials. Among these materials, Kevlar® remains one of the most widely used reinforcements in personal protective systems due to its high tensile strength, low density, excellent specific strength, and favorable energy absorption capability. However, the ballistic performance of Kevlar-based structures is affected by intrinsic limitations, including insufficient interfacial interactions, limited energy transfer between adjacent fibers, and the need for multiple fabric layers to achieve the required protection level. This work addresses the enhancement of Kevlar fiber performance through surface modification and the use of functional and nanostructured coatings. Polymeric, ceramic, carbon-based, and inorganic nanomaterials, including graphene-based materials, carbon nanotubes, silica, metal oxides, and carbides, are considered as promising approaches for improving interfacial adhesion, inter-yarn friction, load transfer, and energy dissipation during high-velocity impact. Among the different nanoscale materials considered, titanium carbide (TiC) represents a promising ceramic reinforcement for Kevlar surface modification due to its favorable mechanical, chemical, and thermal properties. Its incorporation into surface-engineered systems may contribute to improved fiber–coating interactions and enhanced stress transfer while preserving the lightweight character of the protective structure. The efficiency of the modification process is strongly influenced by factors such as surface activation, nanoparticle dispersion, coating morphology and uniformity, deposition technique, and interface architecture. Advanced characterization approaches are also relevant for assessing surface morphology, chemical composition, coating distribution, and the resulting structural and mechanical performance of modified fibers. By integrating nanotechnology with surface engineering, this work highlights promising strategies for tailoring the surface and interfacial properties of Kevlar fibers and for contributing to the development of thinner, lighter, and more efficient ballistic protection systems with potential applications in defense and civil protection.

Title: Movable Platform Guardrail Failure Investigation

Plenary talk

Mr. Robert Oshea

Applied Materials Technologies Inc., USA

Abstract

A guardrail system with a movable platform lift that incorporates movable guardrail components was investigated for failure. The manufacturer used a closed design, employing two hinge assemblies that are welded to a hinge bracket bar that is bolted to another guardrail section and also welded to the swinging guardrail gate. This is a poor design because it does not allow for the hinge brackets to be taken apart for inspection and/or maintenance. This presentation will show that this design is a poor design for fall protection safety equipment, because a failure is not the best way to find out that the hinge system is compromised.

Title: Mechanochemistry – An Emerging Technology on Earth and Beyond

Plenary talk

Prof. Viktor P. Balema

Clemson University, Clemson, SC and ChemImpakt, Milwaukee, WI, USA

Abstract

Mechanochemistry is an emerging field of chemistry and materials science that uses milling, grinding, extrusion, and related techniques to drive chemical reactions between solid reactants [1]. In many cases, mechanochemical transformations do not require liquid solvents, can operate across a broad range of temperatures, atmospheres, and gas pressures, and may be less dependent on Earth gravity than conventional solution-based chemical processes. These features make mechanochemistry potentially suitable for diverse unconventional applications, such as sustainable chemical synthesis, the generation of metastable materials and phases, mechanochemically driven depolymerization of common macromolecules, and the recently proposed manufacturing of materials in off-Earth environments. In the latter case, mechanochemistry can help reduce the reliance of in-space manufacturing on Earth-supplied solvents and process consumables.
This presentation discusses mechanochemical transformations of organic molecules and selected metallic and inorganic ionic solids [1-2] from the perspective of their reaction environments and highlights the potential of solvent-free mechanochemistry for in-space manufacturing. It also outlines possible initial steps toward its practical implementation beyond Earth.

Title: PEEK-Hydroxyapatite Composites for Orthopaedic Implants: Linking Crystallization Behaviour to Mechanical and Wear Performance

Keynote Talk

Dr. Sujoy Kumar Dey

Sharda School of Engineering & Sciences, Sharda University, Greater Noida, India

Abstract

Metallic orthopaedic implants can cause stress shielding and property mismatch with bone, sometimes leading to re-surgery that weak or elderly patients cannot safely undergo. PEEK is a biocompatible polymer and hydroxyapatite (HA) is a bioactive ceramic, so PEEK-HA composites are attractive bone-substitute materials. Their performance depends on how HA changes the crystallization of PEEK. It also depends on how that change carries through to porosity, strength, toughness and wear.

This work connects both aspects for composites with 5, 15 and 30 wt% HA, made by ball milling and compression moulding at 400 °C. Temperature-modulated DSC showed that reversing and non-reversing processes are both active during crystallization between 160 and 330 °C. HA particles act as nucleation sites but also restrict chain mobility, and prolonged high-temperature exposure promotes PEEK degradation. Together these effects give a wide range of crystallinity.

At the property level, increasing HA raised porosity from 1.97% (neat PEEK) to 11.13% and lowered flexural strength from 35.84 to 17.13 MPa. This is attributed to HA agglomeration and weak interfacial bonding. J-integral fracture toughness also decreased as pores and brittle HA increased. Microscratch testing, with H/E and H³/E² indices, showed that the 5 wt% composite (PEEK5HA) had the best surface elasticity and wear response. Its friction, porosity and toughness were also closest to human bone. PEEK5HA is therefore a promising candidate to replace metallic bone implants. The HA fraction has to balance nucleation benefits against bonding loss.

Plenary talk

Prof. Dr. Buruiana Daniela Laura

Dunarea de Jos University of Galati, Romania

Abstract

Improving the durability of road infrastructure and promoting the valorization of industrial waste are important directions in the development of advanced construction materials. The present study investigates the behaviour of a hot-mix asphalt incorporating industrial waste, with particular emphasis on the microstructural changes induced by successive freeze–thaw cycles. The main objective was to evaluate the structural stability of the material and to identify degradation mechanisms generated by repeated thermal stresses. The modified asphalt mixture specimens were subjected to controlled freeze–thaw cycles designed to simulate temperature variations typically encountered during the service life of road structures. The evolution of the material morphology was monitored using scanning electron microscopy (SEM), focusing on changes within the bituminous matrix, the aggregate–binder interfaces, as well as the distribution and integration of particles originating from industrial waste. SEM analysis enabled the identification of microstructural phenomena associated with freeze–thaw exposure, including the formation of microcracks, changes in interfacial regions, and variations in matrix compactness. The results contribute to a better understanding of the influence of industrial waste incorporation on the resistance of asphalt mixtures to cyclic thermal loading and highlight the potential of morphological analysis as a valuable tool for monitoring degradation processes in road materials. The study supports the development of more durable asphalt mixtures and the implementation of circular economy principles through the controlled integration of industrial waste into materials intended for road infrastructure applications.

Title: A Deep Reinforcement Learning Framework for Stabilizing Qubits Against Decoherence and Control Imperfections

Keynote Talk

Prof. Priyanka Brojabasi

Consultants to Government and Industry (CGI), Canada

Abstract

As the basic carriers of quantum information, qubits are extremely vulnerable to unwanted coupling with their surroundings and to imprecise control operations. Processes such as decoherence, energy relaxation, dephasing, and noise in the control signals degrade qubit stability, which in turn restricts how reliably and efficiently quantum computers can operate. In this work, we develop a theoretical, mathematical, and computational framework that applies Deep Reinforcement Learning (DRL) to study and enhance qubit stabilization in noisy environments. We describe the evolution of the qubit with the density matrix formalism and the Lindblad master equation, accounting for relaxation, dephasing, and random fluctuations in the applied control. In this simulated setting, a DRL agent monitors the changing quantum state and chooses control actions, gradually learning adaptive strategies that keep the qubit stable. Training is driven by performance metrics including state fidelity, coherence, purity, and the efficiency of the applied controls. Several DRL methods, namely Proximal Policy Optimization (PPO), Soft Actor-Critic (SAC), and Twin Delayed Deep Deterministic Policy Gradient (TD3), are examined, and their performance can be benchmarked against free (uncontrolled) evolution and standard control techniques. The framework is built to be flexible across a range of physical platforms, such as superconducting circuits, trapped ions, spin systems, neutral atoms, and photonic qubits. Because the evaluation relies on numerical simulations carried out with Python-based quantum simulation and machine-learning libraries, qubit stabilization can be explored without access to physical quantum hardware. Overall, this study lays the computational groundwork for designing intelligent, adaptive control schemes that make qubits more resilient to noise in next-generation quantum technologies.

Abstract

This study addresses the main approaches for increasing the durability and service life of materials employed in the naval industry. The performance of materials in marine applications is strongly influenced by the simultaneous action of corrosive environments, cyclic loading, and mechanical stresses, which may progressively affect their integrity and lead to premature failure. Within this context, the study considers the contribution of material characteristics and advanced surface treatment methods to limiting material degradation.

A particular focus is placed on advanced multilayer protective coating configurations, combining primer layers with hydrophobic finishing coatings to provide enhanced surface protection under demanding marine exposure. The study also considers different approaches for controlling and slowing the corrosion of structural steel. In addition, adequate surface conditioning is emphasized as an important factor for achieving effective coating performance, together with modern technologies intended to strengthen coating adhesion and improve resistance to fatigue-related degradation.

The study further considers sustainable approaches for maintaining material performance through circular economy concepts and remanufacturing practices. These solutions can contribute to prolonging the useful life of high-performance materials while simultaneously lowering environmental impacts and reducing the costs associated with the operation and maintenance of maritime infrastructure. The analysis highlights the main factors that should be considered when choosing protective solutions for materials subjected to complex industrial and marine operating conditions.

Title: Synthesis of Single Crystal Diamond for Applications in High Temperature Electronics

Keynote Talk

Abstract

High-temperature electronics based on epitaxial diamond are promising because of their wide band gap, high thermal conductivity, and large carrier mobility. To take advantage of this opportunity, research was undertaken to develop techniques for the synthesis of both undoped and doped high-quality single crystal diamond suitable for the fabrication of high temperature electronics devices. There are two methods to grow epitaxial diamond – (a) on a suitable diamond seed and (b) on foreign substrates that can carry the epitaxial registry. Single crystal diamond layers (SCD) were also grown on (100) HPHT SCD substrates to allow for continuous layer-by-layer growth. These layers were also doped with nitrogen and boron to make conducting diamond. When doped with nitrogen, yellow and brown diamond was obtained depending on the dopant concentration. When doped with boron, blue diamond with thicknesses upto 2-3 mm was obtained. The goal was to eliminate defects during this growth process. In order to obtain light blue diamond, co-doping with boron and nitrogen has also been attempted. Methods have been developed to grow heteroepitaxial diamond thin layers in order to eliminate the effect of grain boundaries. Two approaches were used to grow (100) and (111) oriented diamond on Pt/MgO and Pt/Sapphire substrates for large area electronics applications. Such highly oriented diamond has been demonstrated.

Title: Preparation and Investigating the Physical, Mechanical and Thermal Performances of Sand/Soil/Recycled HDPE Composites

Invited talk

Abstract

The recycling of waste into materials is a form of recovery that offers a double advantage, such as eco-sustainable sanitation and the availability of new ecological construction materials in Civil Engineering. The present study aimed to develop a composite ecomaterial based on sand,soil and recycled plastic waste melted using a Scheffler solar concentrator (SSC). Then, two types of mix were formulated: a sand/PW mix with ratios of 75/25, 70/30, 65/35 and 60/40, and a sand/soil/PW mix with a ratio of 60/30/10. The SSC enabled an internal melting temperature of 172.42 ◦C to be reached. Specimens measuring 4 × 4 × 16 cm3 were made and tested using 3-point bending, compression, capillary absorption and thermal tests. The best mechanical resistance was obtained with the 65/35 ratio of the sand/PW mix, with average values of 12.15 MPa in 3-point bending and 23.96 MPa in compression. This composite ecomaterial had a water absorption rate of 0.4% and a thermal diffusivity of 0.36mm2/s. On the other hand, the sand/PW/laterite mix had a mechanical strength of 10.1 MPa in 3-point bending and 22.83 MPa in compression, with a water absorption rate of 2.3% and a thermal diffusivity of 0.44 mm²/s. In addition to these initial results, we plan to analyze the effect of thermal shock or wetting-drying cycles on the durability of this composite eco-material. As these properties comply with the established standards, the sand/soil/recycle HPDE composites can be used for applications such as pavers and tiles for interior flooring, and hollow and solid blocks.

Title: From Laboratory to Construction: Machine Learning and Life Cycle Assessment for Scalable Low-Carbon Geopolymer Materials

Invited talk

Dr. Justin Kinda

Université Yembila Abdoulaye Toguéyeni, Burkina Faso

Abstract

Despite extensive research, geopolymer and alkali-activated construction materials remain under-deployed because high compressive strength alone does not establish environmental, economic or operational viability. This conference contribution synthesizes evidence from a PRISMA-adapted critical review of 151 sources selected from 1,424 unique records and translates the findings into a deployment-oriented research framework, with particular attention to West African construction markets. The approach integrates precursor chemistry and reactivity characterization, explainable machine-learning surrogate prediction, uncertainty-aware life cycle assessment (LCA), multi-objective optimization of strength, durability, carbon and cost, experimental validation, and a Performance–Carbon–Cost–Readiness decision matrix. These stages are proposed for future joint implementation, not presented as an experimentally executed end-to-end pipeline. The reviewed literature reports predictive coefficients of determination exceeding 0.90 for selected fly ash–slag strength models, although limited dataset quality and under-representation of tropical precursors constrain transferability. Under harmonized cradle-to-gate, equal-strength comparisons and defensible co-product allocation, quality-weighted evidence supports realistic global warming potential reductions of approximately 30–70% relative to ordinary Portland cement; more extreme reductions depend strongly on allocation conventions. A separate techno-economic case for decentralized calcined-laterite and rice-husk-ash-derived silicate binder production in West Africa estimates a deterministic cost of USD 213–305 per tonne versus USD 220–330 per tonne for imported Portland cement. In 10,000 Monte Carlo iterations, the modeled median binder cost is approximately USD 267 per tonne, with cost parity or better in about 54% of scenarios; imported sodium hydroxide price is the principal sensitivity. These results identify local activator production, durability validation, quality assurance and performance-based certification as decisive pathways toward scalable low-carbon construction. The contribution demonstrates why selection of sustainable binders must shift from isolated strength maximization to context-sensitive, uncertainty-aware deployment decisions.

Title: Fe₃O₄@PDA Loading as a Processing Window Determinant for 4D-Printed Self-Deployable Vascular Stents with Dual Magnetic/NIR Actuation

Keynote Talk

Dr. Rafael Aguirre Flores

Center for Research in Applied Chemistry, Mexico

Abstract

Additive manufacturing of biodegradable vascular stents requires composite formulations that satisfy printability constraints and functional performance requirements at the same time. This work establishes how nanoparticle loading governs ink rheology, printing behaviour, and device-level performance in 4D-printed, self-deployable stents based on polycaprolactone/thermoplastic polyurethane (PCL/TPU) containing 0–15 wt% polydopamine-coated magnetite nanoparticles (Fe₃O₄@PDA). Direct ink writing (DIW) was used as a screening platform to map the rheological processing window, and stent prototypes of the selected formulation were then fabricated by digital light processing (DLP). The 10 wt% formulation offered the best balance between processability and performance: it combined suitable shear-thinning behaviour (n = 0.68) and yield stress (47 Pa) with a 52% increase in glassy storage modulus relative to the neat blend. Shape-fixity and shape-recovery ratios reached 97.3 ± 3.7% and 96.9 ± 1.9%, respectively. Fe₃O₄ cores provide magnetothermal heating while the PDA shell enhances photothermal conversion, allowing the composite to reach its PCL switching temperature (≈55 °C) within about 7 s under NIR and 13 s under AMF. Stents recovered their programmed geometry in 8.0 ± 0.6 s under an alternating magnetic field and 5.1 ± 0.4 s under near-infrared irradiation, and sequential stimulation enabled staged deployment. DLP stents showed a void volume of 0.2 ± 0.4% and an RMS deviation of about 0.2 mm from the CAD geometry, and withstood 50% radial compression without strut fracture. HUVEC viability in extracts exceeded 90% after 72 h, and the material retained 68% of its mass after 12 months at 37 °C. These results link Fe₃O₄@PDA loading, additive manufacturing process parameters, and dual-mode remote deployment in a process–structure–performance framework for biodegradable shape-memory stents, at laboratory proof-of-concept level.

Title: Moving Towards Personalized Medicine with Nanomedicine: 45,000 Patients and Counting

Plenary talk

Prof. Thomas J. Webster

Brown University, USA

Abstract

Nanomedicine is the use of nanomaterials to improve disease prevention, detection, and treatment which has resulted in hundreds of FDA approved medical products. While nanomedicine has been around for several decades, new technological advances are pushing its boundaries. For example, this presentation will present an over 30 year journey of commercializing nanomaterials for neurological and orthopedic implants now in over 45,000 patients to date showing no signs of failure. Current implants face a failure rate of 5 – 10% and sometimes as high as 60% for bone cancer patients. Further, this talk will present future research directions into using atomic layer deposition (ALD) to create such nanostructures on implants to reduce infection and improve bone growth. Sensors grown off of implants using ALD will also be discussed in which cell presence on orthopedic implants can be detected and quantified. Such information can also be communicated to a handheld device to better inform surgeons on chances of implant success or failure. Such sensors can also release pharmaceutical agents and/or nanoparticles on-demand to ensure implant success. Lastly, this talk will cover how Artificial Intelligence (AI) can be combined into today’s orthopedic implants to predict implant success or failure in the years that follow.
