BPNX1040: Bimetallic Nanocubes Decorated on Metal Oxide for Robust Hydrogen Gas Sensing

Yaprak Ozbakir
2025

Hydrogen safety demands highly sensitive H2 sensors with rapid response (< 30 s) to detect leakage at concentrations far below its explosion limit (40,000 ppm). Nanostructured materials based on palladium (Pd) and its alloys emerged as the most promising candidates that meet the standards set by the U.S. Department of Energy for hydrogen sensors. In this study, we are developing novel robust chemiresistive gas sensors employing single-crystalline mesoporous bimetallic alloys (s-meso PdM) nanocubes (NCs) on ordered mesoporous tin (IV) oxide (m-SnO2) for remote and distributed H2 sensors...

BPNX1037: Cellulose-Based Nanosensors for PFAS Detection

Jonghyun Shin
2025

The persistent use of per- and polyfluoroalkyl substances (PFAS) has resulted in their accumulation in ecosystems and biomagnification in humans, posing severe health risks, including kidney, breast, and testicular cancers, along with metabolic disruptions. However, the lack of platforms capable of simultaneous PFAS self-adsorption and self-detection has limited eco-friendly solutions, hindering effective PFAS management. Herein, we introduce an eco-friendly cellulose-based nanosensor platform capable of PFAS separation and monitoring through self-adsorption and self-sensing....

Concrete is the most widely used engineered material in the world and finds use in nearly every aspect of civil infrastructure. Safety concerns posed by the aging of infrastructure combined with the prevalence of concrete in these systems highlights the demand for a concrete-composite capable of structural health monitoring (SHM) while being low-cost and easily implementable. Embedment of electrically conductive forms of carbon such as graphitic fibers and nanotubes allow for concrete and other cementitious composites to act as self-sensors capable of SHM through a...

BPNX1043: Siloxane-Induced Deactivation in Semiconductor Metal Oxides Sensors: Mechanism and Mitigation Strategies

2025

Chemiresistive gas sensors based on semiconductor metal oxides, such as tin oxide (SnO₂), play a critical role in detecting toxic gases and monitoring pollution in industrial and environmental applications. Siloxanes, organic compounds that contain silicon and oxygen atoms and are widely used in personal care products, are commonly present in various environments. The presence of these compounds can significantly degrade sensor performance by modifying the oxide surface, altering its gas adsorption properties, and reducing both sensitivity and selectivity in gas sensing. To address this...

BPNX1041: Enhanced Hydrogen Detection in MOX-Based Gas Sensor via Amphiphilic Copolymer Blending

Chemiresistive hydrogen sensors employing metal oxides (MOX) are known for their high sensitivity, ease of fabrication, and cost-effectiveness. However, the poor dispersion of the MOX nanomaterials on the sensing platform can degrade the gas-sensing performance of films prepared using the drop-casting method. In this research, we have synthesized an amphiphilic copolymer, poly(tetrafluoro propyl methacrylate)-co-poly(oxyethylene methacrylate) (PTPO), using a facile free-radical polymerization technique. The PTPO copolymer serves as a surfactant, significantly enhancing the dispersion of...

Metal-organic frameworks (MOFs) are porous, high surface area materials that consist of metal-cluster nodes connected by organic linkers to form highly ordered structures with various pore geometries and chemical properties. Due to their unique and tunable structure, MOFs have shown substantial promise in a broad range of applications, including chemical sensing, gas adsorption and separation, and catalysis. To investigate the intrinsic properties of MOFs for their sensing performance, single crystals are ideal platforms that mitigate the impact of defects, impurities, and grain...
