Aerogel fibers, combining the nanoporous characteristics of aerogels with slenderness have emerged as a rising star in nanoscale materials science. However, endowing aerogel fibers good strength and high toughness remains elusive due to their porosity fragile mechanics. To address this challenge, paper reports supertough (SAFs) initially started from ionic-liquid-dissociated cellulose via wet-spinning supercritical drying sequence. The assembled nanofibers exhibit specific surface area (372...
Understanding the factors that control microstructure formation in catalyst layers (CLs) of polymer electrolyte fuel cells is vital importance for improving operation these cells. Here, we employ, first time, coarse-grained molecular dynamics simulations to perform a structural analysis microphase segregation occurring during fabrication process CLs. Our mesoscale provide insights into correlations and dynamical behavior different phases layer composite. This versatile computational study,...
Gas diffusion electrodes (GDEs) containing a graded distribution of Nafion were prepared and characterized, their performance as fuel cell cathodes compared to GDEs possessing uniform Nafion. Cyclic voltammetry, electrochemical impedance spectroscopy (EIS), porosimetry are used characterize the variations in properties, ionic conductivity, microstructures. The cathodic was improved over at intermediate high levels polarization when content GDE higher toward catalyst layer/membrane interface...
Hair-like-diameter superelastic conducting fibers, comprising a buckled carbon nanotube sheath on rubber core, are fabricated, characterized, and deployed as weavable wires, biosensors, supercapacitors, strain sensors. These downsized sheath–core fibers provide the demonstrated basis for glucose sensors, electrical interconnects whose performance is undegraded by giant strain, well ultrafast sensors that exploit strain-dependent capacitance changes. Downsized diameter needed electronic...
Current research about resistive sensors is rarely focusing on improving the strain range and linearity of resistance–strain dependence. In this paper, a bi‐sheath buckled structure designed containing carbon nanotube sheets rubber fiber. Strain decrease results in increasing buckle contact by interlayer large resistance. The resulting sensor can be reversibly stretched to 600%, undergoing linear resistance increase as 102% for 0–200% 160% 200–600% strain. This shows high linearity, fast...

The effect of Nafion loading on the electrode polarization characteristics a proton exchange membrane fuel cell is studied with macrohomogeneous model. composition dependence performance rationalized by first relating mass fractions different components to their volume and thereafter involving concepts percolation theory parameterize effective properties cathode catalyst layers. In particular, we explore systematically content performance. For uniform layer, best obtained about 35 wt %,...
Reported results of coarse-grained molecular dynamics simulations rationalize the effect water on phase-segregated morphology Nafion ionomers. We analyzed density maps and radial distribution functions correlated them with domain structures, distributions protogenic side chains, transport properties. The mesoscopic structures exhibit spongelike morphologies. Hydrophilic domains water, protons, anionic chains form a random three-dimensional network, which is embedded in matrix hydrophobic...
Twisting is cool Rubber bands that are stretched and held in an extended shape for a while will extract heat from their surroundings as they allowed to relax, owing reversal of stress-induced crystallization, which exothermic process. Wang et al. examine the potential solid-state cooling twisted fibers, along with configurations such supercoiling, materials including natural rubber, polyethylene, nickel-titanium fibers. The related change entropy material it mechanically deformed. Science ,...
Microstructure changes of the catalyst layers in proton exchange membrane fuel cells (PEMFCs) lead to significant performance degradation and durability limitations, especially under dynamic loading condition; they are investigated experimentally this study simulating effect wet-dry cycles through water intrusion-evaporation flow-through-dehydration experiments, respectively. It is found that cycling processes significantly contributes growth agglomerates as well formation pinholes cracks,...
