This week The Alchemist sheds light on drug delivery, finds out how polymers can run cold and learns of a simple sensor for the "date rape drug" GHB. In the world of power, solar cells can now be turned into highly efficient lasers, we hear, while a way to roll up useful nanowires is developed […]
Shell extract helps rebuild pearly whites | Chemistry World – Researchers in China have shown that the organic component of mother of pearl can help repair damaged teeth, by acting as a template for the mineralisation of tooth enamel.
Oil loving membranes for oil spill clean-ups | Chemistry World – Researchers in China have made a new type of membrane that can separate oil from water and could potentially be used in oil spills, such as the one in the Gulf of Mexico. The membrane works by interacting differently with the substances as it is both superhydrophobic and superoleophilic, so that it repels water but attracts oil. This means that the oil is absorbed through the membrane, but the water can’t penetrate.[cite]10.1039/c2nr33063f[/cite]
