Sensors detect disease markers in breath

A small, thin square of an organic plastic that can detect disease markers in breath or toxins in a building's air could soon be the basis of portable, disposable sensor devices. By riddling the thin plastic films with pores, ...

Better cathode materials for lithium-sulphur-batteries

A team at the Helmholtz-Zentrum Berlin (HZB) has for the first time fabricated a nanomaterial made from nanoparticles of a titanium oxide compound (Ti4O7) that is characterized by an extremely large surface area, and tested ...

How dandelion seeds act as a perfect pipette in the lab

Taraxacum officinale, better known as the common dandelion, is a much-maligned weed cursed the world over for its ability to infest lawns and crops. The plant's paratrooper-like seed dispersal system makes it difficult to ...

First flexible memory device using oxide ferroelectric material

For the first time, researchers have been able to deposit an ultra-thin oxide ferroelectric film onto a flexible polymer substrate. The research team used the flexible ferroelectric thin films to make non-volatile memory ...

'Super sponge' promises effective toxic clean-up of lakes and more

Mercury is very toxic and can cause long-term health damage, but removing it from water is challenging. To address this growing problem, University of Minnesota College of Food, Agricultural and Natural Sciences (CFANS) Professor ...

Iron nanocubes may be key in the future of NO2 sensing

While nanoparticles sound like a recent discovery, these tiny structures have been used for centuries. The famous Lycurgus cup, made by 4th century Roman artisans, features dichroic glass, with gold and silver nanoparticles ...
