Bright semiconductor nanocrystals known as quantum dots give QLED TV screens their vibrant colors. But attempts to increase the intensity of that light generate heat instead, reducing the dots’ light-producing efficiency.

Illustration of graphene nanoribbon

Scanning tunneling microscope image of wide-band metallic graphene nanoribbon (GNR). Each cluster of protrusions corresponds to a singly-occupied electron orbital. The formation of a pentagonal ring near each cluster leads to a more than tenfold increase in the conductivity of metallic GNRs. The GNR backbone has a width of 1.6...

Nano strategy overcomes barriers to plant genetic engineering

Markita Landry files paten for new nanotube technology

Markita Landry and UC Berkeley recently filed patents on a new nanotube technology to delete genes in crop plants without the risk of inserting new genes. Editing the genome of crop plants can boost such traits as disease resistance or drought tolerance. Since the new process adds no genes to the plant genome in the editing process, it conforms to non-GMO requirements in the U.S. and several other countries outside Europe.

Scientists Bring Polymers Into Atomic-Scale Focus

From water bottles and food containers to toys and tubing, many modern materials are made of plastics. And while we produce about 110 million tons per year of synthetic polymers like polyethylene and polypropylene worldwide for these plastic products, there are still mysteries about polymers at the atomic scale.

Freeze Frame: Scientists capture atomic-scale snapshots of artificial proteins

December 5, 2019

Nitash Balsara

Protein-like molecules called “polypeptoids” (or “peptoids,” for short) have great promise as precision building blocks for creating a variety of designer nanomaterials, like flexible nanosheets – ultrathin, atomic-scale 2D materials. They could advance a number of applications – such as synthetic, disease-specific antibodies and self-repairing membranes or tissue – at a low cost.Scientists at Berkeley Lab are the first to use cryogenic electron microscopy (cryo-EM) to image atomic changes in artificial proteins known as “peptoids.” Their findings have implications for the synthesis of soft, 2D materials for a wide variety of applications.
