2D Materials Go Ferromagnetic, Creating a New Scientific Field
"Researchers at the Lawrence Berkeley National Laboratory have successfully demonstrated that two-dimensional (2D) layered crystals held together by van der Waal forces—these include graphene and molybdenum disulfide—can exhibit intrinsic ferromagnetism. Not only did the team demonstrate that it exists in these materials, but the researchers also demonstrated a high degree of control over that ferromagnetism. The discovery could have a profound impact for applications including magnetic sensors and the developing use of spintronics for encoding information."
Washable Heartbeat Sensors Can Now Be Embroidered Onto Clothing
"Embroidery is usually used to adorn fabric with festive designs, but it can now be used to measure heart rates too.
In a new study published in the Journal of the Royal Society Interface, researchers unveiled a fiber optic material that can be produced quickly and then woven, knit, or embroidered into existing fabrics, forming flexible, wearable sensors that seamlessly integrate into clothes."
Graphene Sieve Turns Seawater into Drinking Water
"Graphene-oxide membranes have attracted considerable attention as promising candidates for new filtration technologies. Now the much sought-after development of making membranes capable of sieving common salts has been achieved.
New research demonstrates the real-world potential of providing clean drinking water for millions of people who struggle to access adequate clean water sources."
