Long-Lasting Antimicrobial and Antiviral Surface Coatings

  The Defense Systems Information Analysis Center (DSIAC) was asked to determine if commercial or government off-the-shelf, long-lasting antiviral surface coatings exist.  DSIAC researchers compiled relevant information as of April 2020 and reached out to…

Scalable Manufacturing Process Spools Out Strips of Graphene

MIT engineers have developed a continuous manufacturing process that produces long strips of high-quality graphene. The custom-built, roll-to-roll CVD system makes graphene on copper foil at 1,000 °C. The results, published in the American Chemical Society (ACS), are the first demonstration of an industrial, scalable method for manufacturing high-quality graphene that is tailored for use

Oyster Shells Inspire New Method to Make Superstrong, Flexible Polymers

Researchers at Columbia Engineering have demonstrated for the first time a new technique that takes its inspiration from the nacre of oyster shells, a composite material that has extraordinary mechanical properties, including great strength and resilience. By changing the crystallization speed of a polymer initially well mixed with nanoparticles, the team was able to control

Chemists Perform Surgery on Nanoparticles

A team of chemists led by Carnegie Mellon University’s Rongchao Jin has for the first time conducted site-specific surgery on a nanoparticle. The procedure, which allows for the precise tailoring of nanoparticles, stands to advance the field of nanochemistry. The surgical technique developed by Qi Li, the study’s lead author and a 3rd year graduate
