Bacteria could become a future source of electricity

Nanowerk.com - 5 hours 22 min назад
In recent years, researchers have tried to capture the electrical current that bacteria generate through their own metabolism. So far, however, the transfer of the current from the bacteria to a receiving electrode has not been efficient at all. Now, they have achieved a slightly more efficient transfer of electrical current.

New structural phase transition may broaden the applicability of photo-responsive solids

ScienceDaily.com: Nanotechnology News - 26 марта, 2019 - 17:56
Scientists discovered a new type of structural phase transition of an organic crystal called the photo-triggered phase transition. Under this phenomenon, the crystal, which exhibits a thermal phase transition that is reversible by heating and cooling, transforms to the identical phase upon light irradiation at temperatures lower than the thermal transition temperature. The photo-triggered phase transition may extend functions of photo-responsive solid materials in the future.

Do nanomaterials affect pollinating insects?

Nanowerk.com - 26 марта, 2019 - 12:38
There is concern that pollinating insects are at risk due to nanomaterial exposure. Pollinating insects like bees or bumblebees are potentially exposed to nanomaterials via aerosols, the pollen of contaminated plants and water droplets. Managed pollinators may be additionally exposed in the hives due to direct application of nanomaterials by beekeepers.

Graphene transfer using an off-the-shelf office laminator

Nanowerk.com - 25 марта, 2019 - 15:08
An international team of researchers has demonstrated a simple method for transferring A4-size sheets of CVD graphene from copper foils onto a target substrate using a commercially available polyvinyl alcohol (PVA) polymer foil as a carrier substrate and an off-the-shelf office laminator. This do-it-yourself approach requires few tools and low cost materials - it is safe and easy enough to be carried out in school physics classes. There are no chemicals involved besides water; no spinner; no dangerous etchants.
