Nanocellulose materials by design
Chicago IL (SPX) Oct 06, 2015
Theoretically, nanocellulose could be the next hot supermaterial. A class of biological materials found within numerous natural systems, most notably trees, cellulose nanocrystals have captured researchers' attention for their extreme strength, toughness, light weight, and elasticity. The materials are so strong and tough, in fact, that many people think they could replace Kevlar in ballistic vests and combat helmets for military. Unlike their source material (wood), cellulose nanocrystals are tra ... read more

New 'greener' way to assemble materials for solar applications The efficiency of solar cells depends on precise engineering of polymers that assemble into films 1,000 times thinner than a human hair. Today, formation of that polymer assembly requires solvents t ... more		Nanostructures for contactless control Chemists at Ludwig-Maximilians-Univeristaet (LMU) in Munich have fabricated a novel nanosheet-based photonic crystal that changes color in response to moisture. The new material could form the basis ... more		Scientists build wrench 1.7 nanometers wide Hold up your two hands. They are identical in structure, but mirror opposites. No matter how hard you try, they can't be superimposed onto each other. Or, as chemists would say, they have "chirality ... more
				Standards for triboelectric nanogenerators could facilitate comparisons More than 60 research groups worldwide are now developing variations of the triboelectric nanogenerator (TENG), which converts ambient mechanical energy into electricity for powering wearable electr ... more		Physicists defy conventional wisdom to identify ferroelectric material A team of physicists has defied conventional wisdom by inducing stable ferroelectricity in a sheet of strontium titanate only a few nanometers thick. The discovery could open new pathways to find ne ... more
