Turning up the heat to create new nanostructured metals

Scientists have developed a new approach for making metal-metal composites and porous metals with a 3-D interconnected "bicontinuous" structure in thin films at size scales ranging from tens of nanometers to microns. Metallic ...

4-D imaging with liquid crystal microlenses

Most images captured by a camera lens are flat and two dimensional. Increasingly, 3-D imaging technologies are providing the crucial context of depth for scientific and medical applications. 4-D imaging, which adds information ...

Making tiny antennas for wearable electronics

When it comes to electronics, bigger usually isn't better. This is especially true for a new generation of wearable communication systems that promise to connect people, machines and other objects in a wireless "internet ...

Economizing on iridium

Iridium is an ideal catalyst for the electrolytic production of hydrogen from water—but it is extremely expensive. But now a new kind of electrode made of highly porous material does an excellent job with just a hint of ...

Stabilizing ligands make nanoclusters brighter

Metal nanoclusters that bear tunable surface ligands could help develop next-generation imaging and photocatalytic approaches, suggests work by KAUST researchers.

Clean carbon nanotubes with superb properties

Single-wall carbon nanotubes (SWCNT) have found many uses in electronics and new touch screen devices. Carbon nanotubes are sheets of one atom-thick layer of graphene rolled up seamlessly into different sizes and shapes. ...

Directional control of self-propelled protocells

Synthetic protocells can be made to move toward and away from chemical signals, an important step for the development of new drug-delivery systems that could target specific locations in the body. By coating the surface of ...

Tuning quantum materials with hydrogen gas

Researchers at TU Delft have discovered a method to stretch and compress quantum materials using hydrogen gas. They demonstrated this effect using a tiny string of a material called tungsten trioxide, which acts as a sponge ...

Graphene: The more you bend it, the softer it gets

New research by engineers at the University of Illinois combines atomic-scale experimentation with computer modeling to determine how much energy it takes to bend multilayer graphene—a question that has eluded scientists ...

Novel nanostructures could make smartphones more efficient

EU-funded researchers and partners are pushing the boundaries of the laws of physics, developing nanocomposite materials and nanoelectronic circuits to greatly improve energy, thermal and computing performance. This could ...

ELeCt-ing a better candidate for chemo delivery

Chemotherapy has been the backbone of cancer treatment for decades, but it is notorious for its toxicity to healthy cells, severe side effects, and poor targeting of the intended tumors. Efforts to improve chemotherapy's ...

Precisely poking cells en masse to cure cancer

What if you could cure cancer by re-engineering patients' cells to better target and destroy their own tumors? With the advent of powerful new cellular engineering technologies, this is no longer the stuff of science fiction.

Light at the end of the nanotunnel for future catalysts

Using a new type of nanoreactor, researchers at Chalmers University of Technology, Sweden, have mapped catalytic reactions on individual metallic nanoparticles. Their work could improve chemical processes, and lead to better ...
