Engineers from Stanford turned the mask for snorkeling in a convenient reusable PPE

Professor of bioengineering Manu Prakash, head of a laboratory at Stanford University (USA), last month returned from a holiday spent diving. Upon arriving home, the scientist came down with a bad cold and just in case sat in quarantine for two weeks. There he figured out how to alter a cheap mask for snorkeling in the means of individual protection for doctors opposing COVID-19.

On return to work, Prakash has organized a validation of the design to laboratory equipment and the results were beyond praise. An upgraded version called “Pneumask”, it consists of the mask and the medical filter. Today, 1,500 masks have been sent for further testing in field conditions, an additional 7,000 will be made in the near future.

The main advantage of masks Pneumask – they are reusable. And it is the masks and not respirators that facilitates their use – for example, due to the absence of the purification step. Simply change the filter and disinfect the mask, and you can work on.

About the cost Pneumask nothing is known, but its components is not difficult to find in sports and hardware stores.

The discovery of unknown before “black nitrogen” allowed a paradox table

Researchers from the University of Bayreuth (Germany) can be proud of the double achievement. Experimenting with nitrogen, they got him a hitherto unknown form a new substance. This two-dimensional crystal of atoms of nitrogen, United in zigzag, causing the whole structure resembles graphene, but is much more similar to black phosphorus. Hence the name – […]
