Exchange bias in van der Waals heterostructures

NUS scientists have discovered the exchange bias phenomenon in van der Waals CrCl3/Fe3GeTe2 heterostructures. The exchange bias phenomenon has a number of applications in magnetic sensors and magnetic reading heads, which ...

New materials for extra thin computer chips

Ever smaller and ever more compact—this is the direction in which computer chips are developing, driven by industry. This is why so-called 2-D materials are considered to be the great hope: they are as thin as a material ...

A micro-lab on a chip detects blood type within minutes

Blood transfusion, if performed promptly, is a potentially life-saving intervention for someone losing a lot of blood. However, blood comes in several types, some of which are incompatible with others. Transfusing an incompatible ...

Robust high-performance data storage through magnetic anisotropy

The latest generation of magnetic hard drives is made of magnetic thin films, which are invar materials. They allow extremely robust and high data storage density by local heating of ultrasmall nano-domains with a laser—so ...

'Nanocage' tool untangles (molecular) spaghetti

A team of scientists at the University of Vermont have invented a new tool—they call it a "nanocage"—that can catch and straighten out molecule-sized tangles of polymers.

Graphene: It is all about the toppings

Graphene consists of a single layer of carbon atoms. Exceptional electronic, thermal, mechanical, and optical properties have made graphene one of the most studied materials at the moment. For many applications in electronics ...

Purifying water with the help of wood, bacteria and the sun

According to the United Nations, about one-fifth of the world's population lives in areas where water is scarce. Therefore, technologies to produce clean water from undrinkable sources, such as seawater, river or lake water, ...

Detecting hidden nanostructures by converting light into sound

Researchers at ARCNL have found a way to detect nanostructures buried under many layers of opaque material using high-frequency sound waves induced by light. Their findings could have applications in the semiconductor manufacturing ...

Fluorescent peptide nanoparticles, in every color of the rainbow

The discovery of green fluorescent protein (GFP), which is made by a jellyfish, transformed cell biology. It allowed scientists to stitch the GFP sequence to proteins from other organisms to trace their movements and interactions ...
