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.

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.
