An 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.

Recently, researchers have engineered a next-generation battery technology - known as metal-air batteries - which can be easily fabricated into flexible and wristband-like cells. Although metal-air batteries powered devices still are not ready yet for commercial applications, the current studies have established solid evidence that these devices have provided enormous opportunities to develop the next generation of flexible, wearable and bio-adaptable power sources. Researchers now report a solution to overcoming the current limitation on sluggish reaction kinetics of air cathodes in Mg-air batteries.
