Summary: Materials that are tough and elastic are preferred in protection related activities. Nature produces a lot of materials that satisfy these requirements like rubber, cartilage, etc. However, producing a material with these properties synthetically is a challenge. Researchers from North Carolina State University have created some materials in the class of materials known as ionogels. This type of material is basically polymer structures with liquid salts (liquid at RTP) within them. They have also found many other interesting properties with this material.

Researchers from University of Cambridge in collaboration with UT Sydney have found a possible but unexpected material for this. They have found that the defects in hexagonal Boron Nitride (hBN) produce single photons in a fixed magnetic field. These photons can be used as quantum particles for quantum systems using a property they have known as spin. hBN is easy to produce and scale and what’s different other than the fact that this can be done at room temperature is the different defects produce different signals unlike other such materials.

Silver and chemicals found in wine and chocolate used to create antimicrobial textile coating2/9/2022 Repost by PHYS ORG. Original article by University of Tokyo. Click here to view the full news article. Summary: Silver has been and is being researched a lot for its antimicrobial properties. However, it is not that cheap, so it is not used by common people like us. For the first time, researchers from the University of Tokyo have created a cost effective and convenient way to apply a silver based antimicrobial coating to textiles. They have invented two different methods, one for companies and one which can be used by consumers. The main point in this invention however is that, this is not just a one time use but the coating can remain on the cloth even after many washes so that your clothes can remain odor free for a long time! Read on to find out how they did this. Credit: Ejima et al.
Two-dimensional polymer helps create a new lightweight material that is stronger than steel2/3/2022 Repost by PHYS ORG. Original article by Massachusetts Institute of Technology. Click here to view the full news article. Summary: It was hypothesized long back that if polymers could form 2D sheets, they would be extremely strong, lightweight materials enough to support a building, despite our experience telling us that polymers are not usually that strong. One of the reasons it has been so tough to achieve this is because if even just one monomer shifted in the growing structure the entire structure would begin expanding in 3D. Researchers from MIT have managed to create a method to produce 2D sheets of polymer and as it turns out, the properties are as was predicted opening up lots of possibilities for this material.

Researchers from Rice University discovered that iron corrodes even in presence of supercritical CO2 with trace amount of water. Iron corrodes even in this ‘essentially inert’ fluid due to two reasons. Read more to find out what those reasons are! Credit: Evgeni Penev/Rice University
Written and Published by ScienceAlert. Click here to view the full news article. Summary: Quantum computing has been one the top research topics in the past 5 years or so. One of the major issues with quantum computing has been the ability to control and use a 3 qubit system efficiently. Other than silicon, two other main approaches to creating such a system have been used; superconductors and ions. This problem is important to solve as 3 is the lowest number of bits/qubits which allows for logic operations and error correction. Scientists from three universities, not one but three, have made it possible for a quantum computer to be 99% accurate by just using silicon which we already use in our daily devices. This is a huge milestone as it speeds up the reality of quantum computing. Read more in the article to find out how they did it! Credit: Tony Melov / UNSW

Summary: Indium is one of the rarest metals in the world and is running out due to its usage in mobile screens and computer screens in the form of Indium Tin Oxide (ITO). As expected, scientists have forever been trying to find a replacement as good as this in terms of electronic or optical properties. Researchers from Paragraf and Queen Mary University of London have recently published a paper proving that Graphene could be used instead for these OLED screens as well creating a much cheaper alternative for use. “Our paper is the first paper in the world to demonstrate that graphene can replace ITO in an electronic/optical device. We have shown that a graphene-OLED has identical performance to an ITO-OLED. ITO-OLEDs are widely used as the touch screens on our mobile phones", says Professor Colin Humphreys of Queen Mary and Paragraf. Credit: Unsplash/CC0 Public Domain

Wow…that was a great movie and so long ago too. But in reality, no terminator, although robots are being used in places like Japan in restaurants and hotels. However, soft materials and soft robots are what is being currently researched in many places including NUS MSE. As the title suggests, researchers from Southeast University, China have created a material that behaves like a starfish: changes its color, shape to camouflage and even self heals its tentacles.

Scientists document the presence of quantum spin liquids, a never before seen state of matter12/9/2021 Repost by PHYS ORG.
Original article by Harvard University. Click here to view the full news article. Summary: First of all…this state of matter has nothing to do with a regular liquid state like water. Instead it has all to do with electrons and magnetism. In a regular magnet, all electrons spin in the same or alternate directions: they are in an ordered state; which creates magnetism. In a quantum spin liquid, they are constantly moving around. Theorized in 1973, it has only now been achieved in reality by Havard scientists in collaboration with scientists from University of Innsbruck and QuEra computing in Boston. This state of matter could possibly be used to form topological qubits which can lead to the future of quantum computers. |
