Today, petrochemical compounds and rare metals such as platinum and iridium are used to produce semiconductors for optoelectronics, such as organic LEDs for super-thin TV and mobile phone screens. Physicists at Umeå University in collaboration with.....»»
Researchers hijack solar cell technology to develop a simple spray test for lead
AMOLF researchers have used the special properties of perovskite semiconductors to develop a simple spray test to demonstrate the presence of lead. Perovskite is a material suitable for use in LEDs and solar cells, for example. A lead-containing surf.....»»
Scientists "fingerprint" methane to track a climate change culprit
Methane is the second-most abundant greenhouse gas in Earth's atmosphere, and its emissions have been rapidly—and mysteriously—rising since 2007. Though pervasive, the origin of the colorless compound is tricky to trace, complicating efforts to c.....»»
Low-pH-dependent RNA binding and oligomerization of SID-1 transmembrane family proteins: Implications for RNA transport
In C. elegans, the protein SID1 plays a crucial role in the systemic RNA interference process by facilitating the transport of exogenous double-stranded RNA into the cytoplasm. Previously, Chen-Yu Zhang's group has already demonstrated that intact pl.....»»
