Hybrid nanomaterials bristle with potential

By combining multiple nanomaterials into a single structure, scientists can create hybrid materials that incorporate the best properties of each component and outperform any single substance. A controlled method for making ...

Scientists discover fat-blocking effect of nanofibers

Tiny balls of nano-sized cellulose fibres added to food reduced fat absorption by up to half in laboratory and animal experiments, report scientists from Nanyang Technological University, Singapore (NTU Singapore) and Harvard ...

Graphene enters the stratosphere

The Centre for Advanced Two-Dimensional Materials (CA2DM) at the National University of Singapore (NUS) has teamed up with US-based aerospace company Boreal Space to test the properties of graphene after it has been launched ...

Optical secrets of disulfide nanotubes are disclosed

An international collaborative of researchers has demonstrated a strong light-matter interaction in suspensions and self-assembled films of tungsten disulfide nanotubes (NT-WS2). The results of the research are published ...

Large supercrystals promise superior sensors

Using an artful combination of nanotechnology and basic chemistry, Sandia National Laboratories researchers have encouraged gold nanoparticles to self-assemble into unusually large supercrystals that could significantly improve ...

Fast, cheap and colorful 3-D printing

People are exploring the use of 3-D printing for wide-ranging applications, including manufacturing, medical devices, fashion and even food. But one of the most efficient forms of 3-D printing suffers from a major drawback: ...

Sunscreen for dancing molecules

Since life is mostly based on water, our molecules are moving, vibrating and somersaulting in a liquid environment. But electron microscopy—a technique to study a static version of this nanoworld—has been almost impossible ...

Fire-resistant nanocontainers

Polymers play an essential role in our daily lives, but they also come with an increased risk of fire. Efficient flame retardants are key to ensuring the safety of humans and safeguarding goods from the dangers of accidental ...

Dental plaque is no match for catalytic nanoparticles

Combine a diet high in sugar with poor oral hygiene habits and dental cavities, or caries, will likely result. The sugar triggers the formation of an acidic biofilm, known as plaque, on the teeth, eroding the surface. Early ...

Using nanowires to build all-optical logic gates

A team of researchers at Aalto University in Finland has found a way to use nanowires to build all-optical logic gates—a major step toward building a light-based computer. In their paper published in the journal Science ...
