Diamond microscope

New technique could use tiny diamond defects to reveal unprecedented detail of molecular structures.


Precision growth of light-emitting nanowires

A novel approach to growing nanowires promises a new means of control over their light-emitting and electronic properties. Scientists demonstrated a new growth technique that uses specially engineered catalysts.


Physics breakthrough stalled by magnetic disorder

Exotic new materials called 'ferromagnetic topological insulators' were supposed to be the next big thing, offering potential breakthroughs in electronics and new insights into the physics of solids - but it hasn't happened. Researchers have found out that tinkering with the materials to make the insulators work has actually introduced a disorder that spoils the desired effects.


Nano-hydrogels that attack cancer cells

Hydrogels are materials that are commonly used in everyday objects such as contact lenses or diapers, in order to control humidity. However, chemical engineers developed a new technology based on thermosensitive nanoparticles (nano-hydrogels) to use these materials in the field of biomedicine, as an alternative to achieve controlled release of anticancer drugs.

Turing also present at the nanoscale

In the world of single atoms and molecules governed by chaotic fluctuations, is the spontaneous formation of Turing patterns possible - the same ones that are responsible for the irregular yet periodic shapes of the stripes on zebras' bodies? A team of physicists has for the first time demonstrated that such a process can not only occur, but can also be used for potentially very interesting applications.


Probing qualities at the tips of nanocones

New understanding of electron behaviour at the tips of carbon nanocones could help provide candidates for use as a novel probe in atomic force microscopy.

The power of light-matter coupling at the nanoscale

A theoretical study shows that strong ties between light and organic matter at the nanoscale open the door to modifying these coupled systems' optical, electronic or chemical properties.

'Nanorama Laboratory' - a free tool on safe handling of nanomaterials

The 'Nanorama Laboratory', an interactive online tool on the safe handling of nanoma-terials, is now available in English.


A straightforward, rapid and continuous method to protect MOF nanocrystals against water

Researchers present a one-step, alternative, rapid, and scalable spray-drying synthesis of Metal-Organic Framework (MOF) nanocrystals coated with organic polymers with enhanced hydrolytic stabilities.
