Process for 'two-faced' nanomaterials may aid energy, information tech

ScienceDaily.com: Nanotechnology News - 26 июня, 2020 - 18:47
A team used a simple process to implant atoms precisely into the top layers of ultra-thin crystals, yielding two-sided structures with different chemical compositions. The resulting materials, known as Janus structures after the two-faced Roman god, may prove useful in developing energy and information technologies.

Medical nanotechnology research for COVID-19

Nanowerk.com - 26 июня, 2020 - 11:01
The only options to control and deal with the spread of the Severe Acute Respiratory Syndrome Virus 2 (SARS-CoV-2) are fast, cheap, reliable, and portable means of diagnosing COVID-19 infection (the name of disease caused by SARS-CoV-2); therapeutics to treat the infected; and vaccines to rapidly build up immunization of large parts of the global population. The current crisis demands an urgent analysis of all the available nanotechnology tools. While nanomedicine strategies are in use for the design of the vaccine carriers, there are not enough other nanotechnology approaches being explored to tackle the current outbreak.
