Smaller, faster, cooler: graphene transistors show promise for practical analog signal processors, for magnetic memory devices, and for self-cooling electronic circuits.
‘Good Cholesterol’ nanoparticles are non-toxic and use the need of cancer cells for HDL cholesterol to deliver RNA molecules to silence the expression of cancer-promoting genes.
Porous silica nanoparticles covered with a lipid bilayer deliver large doses of drugs and kill cancer cells a million fold better than do simple liposomes.
Novel biodegradable nanoparticles destroy membranes of drug-resistant ‘superbugs’ without harming blood cell membranes.
Engineering both the pore size and chemical functionality of nanoporous materials affects both the secondary structure and the catalytic activity of the enzymes confined in the nanopores.
Research showing a toxic effect of silver nanoparticles on nitrogen-fixing bacteria in Arctic soil demonstrates the need for more research on nanoparticle environment, health, and safety.
Zyvex Technologies announced that its 54-foot boat named Piranha completed a rough-weather sea test near Puget Sound in the Pacific Ocean, demonstrating record fuel efficiency.
Using proprietary block co-polymer technology, directed self-assembly allows adding block co-polymers that assemble themselves into regular arrays on the surface of a silicon wafer that had been patterned using lithography.
Sputtering a pattern of zinc atoms on a graphene surface, followed by an acid rinse to remove the zinc, also removes exactly one atomic layer of graphene from where ever the graphene was covered with zinc atoms, forming a pattern on the graphene surface that is atomically precise in the vertical dimension. Resolution in the horizontal dimensions is determined by the mask used to sputter zinc.
James C. Ellenbogen writes to provide insight and personal perspective on the world’s first programmable nanoprocessor, achieved as the product of a collaboration between Harvard and MITRE, with the team at MITRE comprising Shamik Das, James Klemic, and Ellenbogen.
