Nanotechnology Now Home > Press > Graphene key for novel hardware security A team of Penn State researchers has developed a new hardware security device that takes advantage of microstructure variations to generate secure keys. CREDIT Jennifer McCann,Penn State Abstract: As more private data is stored and shared digitally, researchers are exploring new ways to protect data against attacks from bad actors. Current silicon technology exploits microscopic differences between computing components to create secure keys, but artificial intelligence (AI) techniques can be used to predict these keys and gain access to data. Now, Penn State researchers have designed a way to make the encrypted keys harder to crack. ....
Our NanoNews Digest Sponsors Home > Press > Antibody binding-site conserved across COVID-19 virus variants: The structural revelation could have implications as a therapeutic target in all SARS-CoV-2 variants A Penn State research team found that the N protein on SARS-CoV-2 is conserved across all SARS-related pandemic coronaviruses (top, from left: SARS-CoV-2, civet, SARS-CoV, MERS). The protein differs from other coronaviruses, such as those that cause the common cold (bottom, from left: OC43, HKU1, NL63 and 229E). CREDIT Kelly Lab/Penn State Abstract: A tiny protein of SARS-CoV-2, the coronavirus that gives rise to COVID-19, may have big implications for future treatments, according to a team of Penn State researchers. ....
Nanotechnology Now Home > Press > Engineers find antioxidants improve nanoscale visualization of polymers Adding antioxidants can push the resolution limit of polymer electron microscopy to reveal a structure smaller in scale (blue) compared to the structure previously observed (pink) in this false-color image. CREDIT Brooke Kuei, Penn State Abstract: Reactive molecules, such as free radicals, can be produced in the body after exposure to certain environments or substances and go on to cause cell damage. Antioxidants can minimize this damage by interacting with the radicals before they affect cells. Engineers find antioxidants improve nanoscale visualization of polymers University Park, PA | Posted on January 8th, 2021 ....
Nanotechnology Now Abstract: A desalination membrane acts as a filter for salty water: push the water through the membrane, get clean water suitable for agriculture, energy production and even drinking. The process seems simple enough, but it contains complex intricacies that have baffled scientists for decades until now. Controlling the nanoscale structure of membranes is key for clean water, researchers find University Park, PA | Posted on January 1st, 2021 Researchers from Penn State, The University of Texas at Austin, Iowa State University, Dow Chemical Company and DuPont Water Solutions published a key finding in understanding how membranes actually filter minerals from water, online today (Dec. 31) in Science. The article will be featured on the print edition s cover, to be issued tomorrow (Jan. 1). ....
