Currently, mobile phones use microwaves for communication and infrared in their cameras. If the problem of creating cheap and efficient terahertz devices can be solved, then it would have various useful applications in security, materials science, communications and medicine. Researchers from University of Cambridge have invented a new type of terahertz detector which is more sensitive due to a new phenomena discovered.

Summary: Machine learning and AI have been playing a major part in the advancement of materials science & engineering as it speeds up the invention and discovery of more new materials and material properties everyday. Using machine learning and AI, researchers from Texas A&M have created the material with the lowest hysteresis ever recorded. This material can therefore be the best material for thermal energy harvesting and storage, which means cooler AC’s in this hot and humid Singapore. Credit: Acta Materialia (2022).

Summary: Superconductors are a class of materials which researchers are interested in, especially in the use of quantum computing. However, not much progress has been made in using these materials for quantum computing because a fundamental property for computing had not been overcome while using superconductors; making electrons travel in the direction u need it to instead of conducting it in all directions. Researchers from TU Delft have figured out a way to make this happen and now only have to figure out how to scale it up to make it available for servers or in supercomputers at the moment. The lead researcher says that there is a very real chance and not of making this happen and not just at a research stage. Read more to figure out how they made this happen! Credit: TU Delft

Summary: Regular 3D printing prints objects layer by layer and is very time consuming and expensive. A new technique called Computed Axial Lithography (CAL) invented by scientists from Germany and USA objects can be made much faster and smoother. Now the researchers from UC Berkeley have improved upon this process to be able to print a finer texture as well using glass. Glass is the preferred material for creating complex microscopic objects like lenses in compact, high quality cameras in smartphones. "Being able to make these components faster and with more geometric freedom could potentially lead to new device functions or lower-cost products,". Read more to find out how the process works!

But now, perovskite is being used to reveal nonlinear optical properties which had only been observed in atomic gases before. Using perovskite, researchers from Kyoto University and Kurume Institute of Technology have discovered a scaling law for high-order harmonic generation in Ca2RuO4. “Uchida concludes that their "findings also provide a foundation for materials design to achieve more efficient nonlinear optical devices."” Read more to find out why this might be interesting!

Summary: Stem cells are young cells that possess the ability to transform into any kind of cell, thereby proving to be quite useful in medicine such as regenerative medicine. Osteopathic medicine focuses on bone growth and development for those with bone problems. Therefore, using stem cells to regenerate bone cells is useful in this department. New nanotechnology invented by a team of researchers at Texas A&M university helps to leverage the body’s regenerative potential by directing these stem cells to form bone tissue.

You may have heard of spintronics, which is creating bits based on the spin state of an electron. Valleytronics is related to spintronics by the fact that now electrons have degrees of freedom in the multiple momentum states (valleys) as well which can be read as bits as well. This is a new field of research with only one book published about yet, Valleytronics in 2D materials. What I think is interesting is that the valleys are able to create an electromagnetic field in the material without any external influence!

Written and published by Thamarasee Jeewandara , PHYS.ORG Click here to view the full news article. Summary: Another long one for you guys! Hydrogels are quite versatile in function but have a fatal flaw: they contain water and water freezes quite easily. So we cannot use this excellent material at low temperatures. How then to overcome this? Inspired by water bears, researchers from the Zheijang University in China have figured out a way to do so using a trehalose network to prevent the water from crystallizing. This allows the hydrogel to remain tough, stretchable and have good conductivity even at low temperatures. Read more to find out how versatile this method turns out to be and the stuff they did, for those interested in the details!!! Credit: Science Advances (2022). DOI: 10.1126/sciadv.abl5066

Summary: Nowadays, we are moving more towards sustainable and renewable solutions…trying to save the earth from climate change. Researchers from the University of Cambridge have created a more sustainable renewable energy device than current renewable technologies such as using biofuel. The material aspect to this solution is the game changer as using photosynthetic bacteria to create electricity has been thought and tried before. “"Most scientists assumed that the bottleneck was on the biological side, in the bacteria, but we've found that a substantial bottleneck is actually on the material side."” Read more to find out how they managed to produce more than at least 10x the amount produced usually using nature!

Inspired by how bread is baked, where it needs to be baked at the right temperature and right amount of time to be delicious; A team at Sun Yat-Sen University from China have used the change in opacity of thermoresponsive hydrogels to create a ‘double lock’ using temperature and time.
