Cotton, PLA-phytochemical encapsulated nanofiber-based face mask for combating the spread of COVID-19 infections

facemaskAn estimated 6.8 billion face masks are used around the world each day, which ultimately are incinerated, sent to landfills or simply dumped in the environment, providing a glimpse of a forthcoming severe global environmental crisis. Many of these synthetic face masks are non-biodegradable in nature. To address this issue, researchers have developed a 3-layered biodegradable, antibacterial, breathable, herbal-extract based, and needleless electrospun face mask.

Exploring the optical behavior of highly dense and randomly distributed nanowire arrays

nanowire-arrayVertical semiconductor nanowire arrays are a promising material for retinal prostheses, which could help restore the eyesight of people suffering from severe retinal diseases. These nanowires could also be used to fabricate bio-inspired photoreceptors and lightweight, highly efficient photovoltaics. In new work, scientists present theoretical and experimental studies on the microscopic optical behavior of highly dense and randomly distributed nanowire arrays embedded in a transparent polymer.

Nanowire meshes to improve electrochemical devices

nanomeshBy re-designing interconnected nanowire networks, researchers fabricated novel nanostructured current collectors, which are the first to combine very high surface area, high porosity, substantially large pores and mechanical flexibility. Thanks to its ordered microstructure, the material can uniquely combine high porosity of cellular metal foams with high surface area of state-of-the-art nanoporous dealloyed metals, which allowed it to surpass the electrochemical performance of up to 300-thicker commercial electrodes.
