A dual-gated graphene transistor designed to operate directly in liquid environments has achieved up to 20 times the signal gain of conventional designs while cutting sensor drift by more than 15 ...

Recently I came across some non-contact liquid level sensors and gathered them out of curiosity. They have been available in the market for the past few years, but this time I was lucky enough to get ...

Schematic diagram providing an overview of this review. Liquid crystals can be categorized into nematic, smectic, columnar, and cholesteric liquid crystals. Recently, metasurfaces have been integrated ...

Ions influence conductivity and mobility in molecular liquid crystals, affecting electrical behavior, stability, and performance in both established and emerging technologies. (Nanowerk Spotlight) The ...

If you dissolve sugar in hot water and then cool it down, you'll see pure sugar crystals form while impurities stay in the liquid. You can even watch the beautiful sugar crystals slowly grow in the ...

(Nanowerk Spotlight) Liquid crystals (LCs) are a distinct state of matter exhibiting properties between crystalline solids and isotropic liquids. Their partially ordered structure gives rise to unique ...
