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,...

Appearance and origin of oxidation in 2D nanomaterials akin to tree rings

tree-ringsMany 2D materials with atomic-scale thicknesses suffer from oxidation and degradation effects under ambient conditions, which is one of the biggest obstacles in their practical applications. A 75-month study used atomic force microscopy to investigate the long-term evolution of oxidative defects on transition metal dichalcogenides (TMDs). Intriguingly, the researchers found that long-term storage in ambient conditions led...
