Spinning yarn for a wash-and-wear energy harvester

To Georgia Tech’s Zhong Lin Wang, even tossing and turning in bed is a possible source of renewable energy. Wang’s group has made energy-harvesting yarns—primarily composed of common garment materials like polyester, cotton, silk, and wool—that can be woven into brightly colored, washable, power-generating textiles (ACS Nano ۲۰۱۷, DOI: 10.1021/acsnano.7b07534). Sewn into socks, sweaters, and other clothes, the … Continue reading

Ironing out graphene’s wrinkles

With a carefully engineered substrate, researchers can grow high-quality graphene free of troublesome wrinkles that often form during manufacture. The supersmooth two-dimensional material has improved electrical properties over rumpled graphene grown by the usual methods (ACS Nano 2017, DOI: 10.1021/acsnano.7b06196). In theory, pristine graphene has superlative electrical, mechanical, and other properties that could be used to make … Continue reading

When it comes to halogen bonds, electrostatics aren’t the σ-hole story

Researchers say charge-transfer should officially join σ-holes in halogen bond explanation Scientists in the US and Germany have added to an ongoing debate over the nature of halogen bonds.1 Their data provides new evidence that scientists should not ignore charge-transfer when explaining the bond’s behaviour. Halogen bonds are a type of supramolecular interaction. According to … Continue reading

Molecular box treats chemists to a strained surprise

Introducing pillar[4]pyridinium – the first of a new family of macrocycles Scientists in Poland have made the most compact multiply charged macrocycle to date. Pillar[4]pyridinium is a cyclic tetramer consisting of four pyridyl units with methylene bridges between their nitrogens and para carbons. The quadruply charged molecule has a very symmetrical and incredibly strained structure. … Continue reading

DNA origami hits the big time

Molecular architects have developed a quartet of methods that could propel DNA nanotechnology into wider use. Together, the techniques offer a tool kit to mass-produce larger and more complex DNA structures than ever before, paving the way for applications from drug delivery systems to nanoelectronics. “I think people will now see that DNA nanotechnology is … Continue reading
