Applications for porous fibrous materials range from electrochemical substrates to web reinforcement in polymeric composite materials. The details of local load transfer are studied in a class of cost-effective, stochastic fibrous networks used in battery applications , which form the substrate for a composite electrode. The connectivity of these materials(More)
Maximum depth-to-particle-dimension ratios in which systems can be treated as two-dimensional ͑2D͒ rather than three-dimensional ͑3D͒ systems in determining percolative properties have not been reported. This problem is of great technological significance. 3D solutions for percolation in even low-density systems pose much more intensive computational(More)
We performed coupled theoretical/experimental studies on Li-ion cells to quantify reductions in anode resistivity and/or contact resistance between the matrix and the current collector with the addition of amorphous carbon coatings and anode compression. We also aimed to identify microstructural changes in constituent particles due to anode compression,(More)
Several promising Li-ion battery technologies incorporate nanoarchitectured carbon networks, typically in the form of whisker/ particle blends bonded with thermoplastic binders to form the anodes. Degradation of these materials is currently a persistent problem, with damage presenting as blistering and/or delamination of the electrode. Both material(More)
SERS biosensor has demonstrated remarkable potential to analyze various bio/chemical targets with ultrahigh sensitivity. However, the development of universal SERS biosensing platforms with a uniform and reproducible structure that can quantitatively detect a broad range of trace analytes remains a significant challenge. The production of SERS nanotags with(More)
Increased thermal conductivity, electronic conductivity, and reversible capacity (i.e., reduced irreversible capacity loss, or ICL) have been demonstrably achievable by compression of anodes into higher volume fraction plates, though excessive compression can impair Li-ion battery performance. In our previous study, we correlated conductivity and(More)
Coupled computational fluid dynamics and finite element analyses were used to determine the material properties of the egg and jelly layer of the sea urchin Arbacia punctu-lata. Prior experimental shear flow results were used to provide material parameters for these simulations. A Neo-Hookean model was used to model the hyperelastic behaviors of the jelly(More)
