Coatings Influence Nanoparticle Toxicity

(C&EN) To understand the toxicity of nanoparticles, most scientists have focused on the materials’ metal cores. But now researchers have shown that the chemicals that decorate silver nanoparticle surfaces can change their toxicity. Known for their antibacterial properties, silver nanoparticles find use in medical devices, textiles, and other products. In 2010, Mitchel Doktycz of Oak Ridge National Laboratory and his colleagues reported that unlike other silver nanoparticles, those with fatty oleate coatings were not toxic to bacteria...1/12

Shortages spur race for helium-3 alternatives

(RSC News) The Japan Proton Accelerator Research Complex (J-PARC), based in Tokai, was supposed to be one of the leading facilities of its kind, allowing an unprecedented view of microstructures in the life and physical sciences. But when the $1.5 billion (£1 billion) facility opened in 2009, it was missing something important: helium-3, a neutron-detector material. Thanks to a global shortage, which came to light the year before, availability of helium-3 has plummeted while prices have skyrocketed...1/12
