A Nano-IR Probe for Proteins in Liquid Environments

A new technique using infrared (IR) light revealed how the self-assembly of proteins is affected by environmental conditions in a surrounding liquid. This nanoscale probe of soft matter in a liquid matrix will facilitate advances in biology, plastics processing, and energy-relevant applications such as electrocatalysts and batteries.

Structures Signal Fresh Targets for Anticancer Drugs

Researchers from Genentech used a suite of methods, including small-angle x-ray scattering, to learn how an assembly of three proteins works together to transmit signals for cell division. The work reveals new targets for the development of drugs that fight certain types of cancer, including lung, colorectal, and pancreatic cancer. Read more »PPT-icon-35 PDF-icon-35

A New Material System for Mixed-Plastic Recycling

Scientists have designed a new material system to overcome one of the biggest challenges in recycling consumer products: mixed-plastic recycling. Their achievement will help enable a much broader range of fully recyclable plastic products and brings into reach an efficient circular economy for durable goods like automobiles. Read more »

Highly Selective Methane to Methanol Conversion on Inverse SnO2/Cu2O/Cu(111) Catalysts: Unique Properties of SnO2 Nanostructures and the Inhibition of the Direct Oxidative Combustion of Methane

Inverse catalysts generally consist of oxide nanoparticles supported on metal substrates, which can exhibit exceptional catalytic properties. The small SnO2 nanoparticles uniformly dispersed on a Cu2O/Cu(111) substrate enabled a unique SnO2–Cu2O interface that can completely convert methane to methanol directly under the environments of oxygen and water.

Scientists Grow Lead-Free Solar Material With a Built-In Switch

A new ferroelectric material—grown in the lab from cesium germanium tribromide (CGB)—opens the door to an easier approach to making solar cell devices. Unlike conventional solar materials, CGB crystals are inherently polarized, where one side of the crystal builds up positive charges and the other side builds up negative charges, no doping required.

Multilayer Stack Opens Door to Low-Power Electronics

Researchers found that a multilayer stack of ultrathin materials exhibits a phenomenon called negative capacitance, which reduces the voltage required for transistor operation. The material is fully compatible with today’s silicon-based technology and is capable of reducing power consumption without sacrificing transistor size or performance.

An Expanded Set of DNA Building Blocks for 3D Lattices

Researchers studied 36 DNA-based molecular junctions and discovered factors that yield superior self-assembled 3D lattice structures. The work expands the set of building blocks for lattices that can scaffold molecules into regular arrays, from proteins for structure studies to nanoparticles for nano-antennas and single-particle sensors.
