Single-celled architects inspire new nanotechnology

Diatoms are tiny, unicellular creatures, inhabiting oceans, lakes, rivers, and soils. Through their respiration, they produce close to a quarter of the oxygen on earth, nearly as much as the world's tropical forests. In addition ...

A safe and effective way to whiten teeth

In the age of Instagram and Snapchat, everyone wants to have perfect pearly whites. To get a brighter smile, consumers can opt for over the counter teeth-whitening treatments or a trip to the dentist to have their teeth bleached ...

Hydrogen from water in iron nanotruss structures

Swedish researchers have discovered a new and efficient way to use electrocatalysis to produce hydrogen gas from water. Instead of using expensive and difficult-to-obtain platinum electrodes, the new method uses electrodes ...

Water desalination picks up the pace

A membrane made of porous carbon-fiber structures grown on a porous ceramic substrate is more efficient at filtering seawater than existing similar membranes.

A silicon-nanoparticlephotonic waveguide

A new way to efficiently guide light at tiny scales has been demonstrated by an all-A*STAR team. Their method, which involves lining up silicon nanoparticles, is promising for applications such as light-based integrated circuits, ...

Slippery when dry

Anyone who has ever taken their car in for an oil change recognizes the importance of reducing the friction that arises when steel touches steel.

Brain function partly replicated by nanomaterials

The brain requires surprisingly little energy to adapt to the environment to learn, make ambiguous recognitions, have high recognition ability and intelligence, and perform complex information processing.

The future of electronics is chemical

We can't cram any more processing power into silicon-based computer chips. But a paper published in Nature overnight reveals how we can make electronic devices 10 times smaller, and use molecules to build electronic circuits ...

On the path to new high-performance transistors

The electronics industry expects a novel high-performance transistor made of gallium nitride to offer considerable advantages over present-day high-frequency transistors. Yet many fundamental properties of the material remain ...

Carbon is the new black

Engineers with the University of Cincinnati are leveraging a partnership with Wright-Patterson Air Force Base to create clothing that can charge your cell phone.

Nanoparticles give immune cells a boost

Programming the body's immune system to attack cancer cells has had promising results for treating blood cancers such as lymphoma and leukemia. This tactic has proven more challenging for solid tumors such as breast or lung ...

Manipulating single atoms with an electron beam

All matter is composed of atoms, which are too small to see without powerful modern instruments including electron microscopes. The same electrons that form images of atomic structures can also be used to move atoms in materials. ...
