Large-scale (156 mm × 156 mm) quasi-omnidirectional solar cells are successfully realized and featured by keeping high cell performance over broad incident angles (θ), via employing Si nanopyramids (SiNPs) as surface texture. SiNPs are produced by the proposed metal-assisted alkaline etching method, which is an all-solution-processed method and highly simple together with cost-effective. Intere...

Leakage rates are evaluated for a landfill barrier system having a compacted clay liner (CCL) underlain by a vadose zone of variable thickness. A numerical unsaturated flow model SEEP/W is used to simulate the moisture flow regime and steady-state leakage rates for the cases of unsaturated zones with different soil types and thicknesses. The results of the simulations demonstrate that harmonic ...

The reactive-templated grain growth (RTGG) method is a powerful fabrication technique for producing textured ceramics having enhanced performance compared to those of conventionally prepared non-textured ceramics, for various functional materials. Its wide applicability is demonstrated by the fact that the RTGG method using β-Co(OH)2 templates gave textured ceramics of p-type thermoelectric lay...

BACKGROUND standing on textured surfaces or wearing textured shoe insoles can alter balance performance. This evidence, although inconclusive, offers a potential intervention for improving balance in older adults. This study explored the effect of standing on textured surfaces on double-limb balance in older adults and changes in muscle activity as a possible mechanism of effect. METHODS 50 h...

Angular dependency of the reflectivity of two distinct nano-textured and planar reference liquid-phase crystallized silicon solar cells are investigated. We show that nano-textured layers outperform planar devices for all incident angles. OCIS codes: 040.5350, 310.6845

This work presents the development of a portable, wireless activity monitoring system for the estimation of biomechanical gait parameters. The system uses a pair of instrumented insoles able to measure pressure from different points of the foot including four commercial piezoresistive pressure sensors and a three-axis accelerometer, all together integrated in the insole to determine foot forces...

Conclusions While statistical analysis did not show any statistical difference, all subjects in the study reported some level of relief of symptoms during the magnetic insole phase of therapy. This was further supported by anecdotal evidence of all subjects wishing to continue using the magnetic insoles after the study had finished.

This study examined packing (pocketing or holding accepted food in the mouth) in 3 children who were failing to thrive or had inadequate weight gain due to insufficient caloric intake. The results of an analysis of texture indicated that total grams consumed were higher when lower textured foods were presented than when higher textured foods were presented. The gram intake was related directly ...
