Scientists in Australia have developed a new type of electronic material that is touch-responsive and just a fraction of the thickness of current smartphone screens. This could see it one day find use in next-generation mobile devices, and because of its incredible thinness and flexibility, could be manufactured at large scale using roll-to-roll (R2R) processing like a printed newspaper.

The breakthrough comes from researchers at RMIT University, who began with a material commonly used in today’s mobile touchscreens called indium-tin oxide. This transparent material is highly conductive but does have its shortcomings, chiefly that it is very brittle, so the team sought to give it better pliability by greatly reducing its thickness.

Strongly interacting bosons have been predicted to display a transition into a superfluid ground state, similar to Bose–Einstein condensation. This effect is now observed in a double bilayer graphene structure, with excitons as the bosonic particles.

MIT physicists have created a superfluid gas, the so-called Bose-Einstein condensate, for the first time in an extremely high magnetic field. The magnetic field is a synthetic magnetic field, generated using laser beams, and is 100 times stronger than that of the world’s strongest magnets. Within this magnetic field, the researchers could keep a gas superfluid for a tenth of a second—just long enough for the team to observe it. The researchers report their results this week in the journal Nature Physics.

A superfluid is a phase of matter that only certain liquids or gases can assume, if they are cooled to extremely low temperatures. At temperatures approaching absolute zero, atoms cease their individual, energetic trajectories, and start to move collectively as one wave.

In an unprecedented experiment, two teams of scientists on either sides of the Atlantic have replicated a material that was previously not produced anywhere on Earth.

As NPR reports, the replication of this powerful compound could have huge implications not just for the manufacturing of high-end machinery, but also for international relations to boot.

Called tetrataenite, the primarily iron-and-nickel compound is normally able to cool for millions of years as it tumbles around in asteroids. As a press release out of the University of Cambridge notes, the researchers who worked in tandem with Boston’s Northeastern University found that if they add phosphorous to the mix, they were able to make synthetic tetrataenite.

When 2D layered materials are made thinner (i.e., at the atomic scale), their properties can dramatically change, sometimes resulting in the emergence of entirely new features and in the loss of others. While new or emerging properties can be very advantageous for the development of new technologies, retaining some of the material’s original properties is often equally important.

Researchers at Tsinghua University, the Chinese Academy of Sciences and the Frontier Science Center for Quantum Information have recently been able to realize tailored Ising superconductivity in a sample of intercalated bulk niobium diselenide (NbSe₂), a characteristic of bulk NbSe₂ that is typically compromised in atomically thin layers. The methods they used, outlined in a paper published in Nature Physics, could pave the way towards the fabrication of 2D thin-layered superconducting materials.

“Atomically thin 2D materials exhibit interesting properties that are often distinct from their bulk materials, which consist of hundreds and thousands of layers,” Shuyun Zhou, one of the researchers who carried out the study, told Phys.org. “However, atomically thin films/flakes are difficult to fabricate, and the emerging new properties are sometimes achieved by sacrificing some other important properties.”

Gene therapies can scale economically, but not just with practices adapted from traditional biologics. According to Avantor, gene therapies pose unique material, workflow, and partnering challenges.

In the effort to efficiently convert heat into electricity, easily accessible materials from harmless raw materials open up new perspectives in the development of safe and inexpensive so-called thermoelectric materials. A synthetic copper mineral acquires a complex structure and microstructure through simple changes in its composition, thereby laying the foundation for the desired properties, according to a study published recently in the journal Angewandte Chemie.

The novel synthetic material is composed of copper, manganese, germanium, and sulfur, and it is produced in a rather simple process, explains materials scientist Emmanuel Guilmeau, CNRS researcher at CRISMAT laboratory, Caen, France, who is the corresponding author of the study. The powders are simply mechanically alloyed by ball-milling to form a precrystallized phase, which is then densified by 600 degrees Celsius.

The Celsius scale, also known as the centigrade scale, is a temperature scale named after the Swedish astronomer Anders Celsius. In the Celsius scale, 0 °C is the freezing point of water and 100 °C is the boiling point of water at 1 atm pressure.

Tohid Didar and Jeff Weitz had a solution, but they also had a problem.

Didar, an associate professor of engineering and Weitz, a hematologist, professor of medicine and executive director of the Thrombosis & Atherosclerosis Research Institute, had collaborated to create a novel and highly promising material to improve the success of vascular grafts, but they needed a better way to test how well it worked.

Their revolutionary idea was an engineered non-stick surface combined with biological components that can repel all but a targeted group of cells — those that form the natural lining of the body’s veins and arteries.

Researchers at Pacific Northwest National Laboratory (PNNL) are studying the atomic-level changes in metals undergoing shear deformation in order to deduce the effects of physical forces on these materials, according to a report by Phys.org published on Monday.

The work could lead to many new and improved applications such as longer-lasting batteries and lighter vehicles.
