Researchers Identify Piezoelectric Materials with One Atomic Layer Thickness

There are a handful of naturally occurring materials, known as piezoelectric materials, that generate electricity if you bend, stretch or apply another mechanical force to them, and vice versa – if you apply a voltage across them, they'll deform accordingly.

Silver, Glass and Chromium Nanostructure Allows One-Way Transmission of Visible Light

The light-warping structures known as metamaterials have a new trick in their ever-expanding repertoire. Researchers at the National Institute of Standards and Technology (NIST) have built a silver, glass and chromium nanostructure that can all but stop visible light cold in one direction while giving it a pass in the other. The device could someday play a role in optical information processing and in novel biosensing devices.

New, Inexpensive Method to Separate Oil-Water Nanoemulsion

Whenever there is a major spill of oil into water, the two tend to mix into a suspension of tiny droplets, called an emulsion, that is extremely hard to separate — and that can cause severe damage to ecosystems. But MIT researchers have discovered a new, inexpensive way of getting the two fluids apart again.

New Antibacterial Material Based on Gold Nanoparticles

Bacteria love to colonize surfaces inside your body, but they have a hard time getting past your rugged, salty skin. Surgeries to implant medical devices often give such bacteria the opportunity needed to gain entry into the body cavity, allowing the implants themselves to act then as an ideal growing surface for biofilms.

Novel Crystal Forms Three Atoms Thick Flexible, Switchable Material

Computer simulation shows how to make a crystal that would toggle like a light switch between conductive and non-conductive structures; this could lead to flexible electronic materials and enable a cell phone to be woven into a shirt

New Type of Infrared Photodetector Based on Nanoporous ZnO/n-Si Structure

Experiments aimed at devising new types of photodetectors have been triggered by the increasing use of optoelectronic devices in personal electronics, cameras, medical equipment, computers and by the military. Professor Zhao Kun and co-researchers at the State Key Laboratory of Petroleum Resource and Prospecting, part of the China University of Petroleum in Beijing, have proposed a new type of infrared photodetector.

Nano-Coated Silver Textiles Lose Less Silver During Washing

If it contains 'nano', it doesn't primarily leak 'nano': at least that's true for silver-coated textiles, explains Bernd Nowack of the Technology and Society division at Empa. During each wash cycle a certain amount of the silver coating is washed out of the textiles and ends up in the waste water. Empa analysed this water; it turned out that nano-coated textiles release hardly any nano-particles.

Addition of Water Molecules Leads to Increase in Distance Between Graphite Oxide Layers

Physicists from Umeå University and Humboldt University in Berlin have solved a mystery that has puzzled scientists for half a century. They show with the help of powerful microscopes that the distance between graphite oxide layers gradually increases when water molecules are added. That is because the surface of graphite oxide is not flat, but varies in thickness with "hills" and "valleys" of nanosize. The new findings are published in the scientific journal Nano Letters.
