International Advanced Research Centre for Powder Metallurgy and New Materials (ARCI), an autonomous R&D Centre of the Department of Science and Technology (DST), and University of Hyderabad (UoH) together with the help of Mekins Industries Ltd. (MIL), have developed a UVC based disinfection trolley to fight against COVID-19 by rapid cleaning of the hospital environment.
In the wake of the COVID-19 pandemic, the U.S. Centers for Disease Control and Prevention recommends that people wear masks in public. Because N95 and surgical masks are scarce and should be reserved for health care workers, many people are making their own coverings. Now, researchers report in ACS Nano that a combination of cotton with natural silk or chiffon can effectively filter out aerosol particles — if the fit is good.
Scientists from International Advanced Research Centre for Powder
Metallurgy and New Materials (ARCI) an autonomous institute under the
Department of Science & Technology, Govt. of India in collaboration with
Nanomechanics Inc., Oak Ridge, USA have jointly developed an advanced
tool for mapping nano-mechanical properties of materials like
multi-phase alloys, composites, and multi-layered coatings.
Researchers at Japan Advanced Institute of Science and Technology
(JAIST) have successfully fabricated suspended graphene nanomesh in a
large area by helium ion beam microscopy. Six nm diameter nanopores were
uniformly patterned on the 1.2 um long and 500 nm wide suspended
graphene. By systematically controlling the pitch (nanopore's center to
nanopore's center) from 15 nm to 50 nm, a series of stable graphene
nanomesh devices were achieved. This provides a practical way to
investigate the intrinsic properties of graphene nanomesh towards
applications for gas sensing, phonon engineering, and quantum
