Magnetic field turns handed superconductor into liquid crystal-like nematic state

16-Sep-2021

Researchers at the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in Hamburg and RWTH Aachen University have suggested a surprising connection between the nematic behavior of a superconductor in a magnetic field — a state that resembles liquid crystals used in LCDs — and its ...

Janus graphene opens doors to sustainable sodium-ion batteries

Ten times the energy capacity of standard graphite

31-Aug-2021

In the search for sustainable energy storage, researchers at Chalmers University of Technology, Sweden, present a new concept to fabricate high-performance electrode materials for sodium batteries. It is based on a novel type of graphene to store one of the world's most common and cheap metal ...

Pioneering breakthrough: Creation of the most perfect graphene

New discovery allows for scalable production of fold-free and ad-layer free single-crystal graphene

27-Aug-2021

A team of researchers led by Director Rod Ruoff at the Center for Multidimensional Carbon Materials (CMCM) within the Institute for Basic Science (IBS), including graduate students at the Ulsan National Institute of Science and Technology (UNIST), have achieved growth and characterization of ...

How ions get their electrons back

What happens when ions are passing through solid materials? It is nearly impossible to observe this directly, but scientists at TU Wien found a way to overcome this problem

17-Aug-2021

Very unusual atomic states are produced at TU Wien: Ions are created by removing not just one but 20 to 40 electrons from each atom. These “highly charged ions” play an important role in current research. For a long time, people have been investigating what happens when such highly charged ions ...

New mechanism of superconductivity discovered in graphene

Placing a 2D Bose-Einstein condensate in the vicinity of a graphene layer confers superconductivity to the material

20-Jul-2021

Superconductivity is a physical phenomenon where the electrical resistance of a material drops to zero under a certain critical temperature. Bardeen-Cooper-Schrieffer (BCS) theory is a well-established explanation that describes superconductivity in most materials. It states that Cooper pairs of ...

Atomic-scale tailoring of graphene approaches macroscopic world

"We are excited of the prospect of creating new materials that are designed starting at the atomic level, based on this method"

22-Jun-2021

Properties of materials are often defined by imperfections in their atomic structure, especially when the material itself is just one atom thick, such as graphene. Researchers at the University of Vienna have now developed a method for controlled creation of such imperfections into graphene at ...

What we know about water may have just changed dramatically

New research points to a potentially strong impact from water purification to drug manufacturing

08-Jun-2021

Water is weird - and yet so important. In fact, it is one of the most unusual molecules on Earth. It boils at a temperature it shouldn't. It expands and floats when it is in the solid-state. Its surface tension is higher than it should be. Now, new research published in the journal Nature has ...

Superflimsy graphene turned ultrastiff by optical forging

Stiffened graphene opens up avenues for novel applications

28-May-2021

Graphene is an ultrathin material characterized by its ultrasmall bending modulus, superflimsiness. Now the researchers at the Nanoscience Center of the University of Jyväskylä have demonstrated how an experimental technique called optical forging can make graphene ultrastiff, increase its ...

“Bite” defects in bottom-up graphene nanoribbons

Important findings in the context of the potential applications of graphene nanoribbons in nanoelectronics and quantum technology

27-May-2021

Scientists at Empa and EPFL have identified a new type of defect as the most common source of disorder in on-surface synthesized graphene nanoribbons, a novel class of carbon-based materials that may prove extremely useful in next-generation electronic devices. The researchers identified the ...

A new form of carbon

Not graphene: researchers in Germany and Finland discover new type of atomically thin carbon material

25-May-2021

Carbon exists in various forms. In addition to diamond and graphite, there are recently discovered forms with astonishing properties. For example graphene, with a thickness of just one atomic layer, is the thinnest known material, and its unusual properties make it an extremely exciting candidate ...
