New machine-learning approach identifies one molecule in a billion selectively, with graphene sensors
Graphene's 2D nature, single molecule sensitivity, low noise, and high carrier concentration have generated a lot of interest in its application in gas sensors. However, due to its inherent non-selectivity, and huge p-doping in atmospheric air, its a.....»»
US public water supply is a local source of phosphorus pollution, finds study
In the United States, public water systems are sometimes dosed with phosphate to reduce copper levels and lead pipe corrosion. This practice can help avert humanitarian disasters like the Flint water crisis, but because phosphorus can contribute to e.....»»
Oxygen groups key to unlocking graphene"s antimicrobial potential, say scientists

How jasmonate signaling is enhanced under phosphorous-deficient conditions in plant physiology
Phosphorus (P) is a macronutrient essential for various biological processes in plants. Inorganic phosphate (Pi) deficiency modulates the signaling pathway of the phytohormone jasmonate (a fatty acid compound ubiquitous in the plant kingdom and cruci.....»»
Reaching superconductivity layer by layer
Imagine a sheet of material just one layer of atoms thick—less than a millionth of a millimeter. While this may sound fantastical, such a material exists: it is called graphene and it is made from carbon atoms in a honeycomb arrangement. First synt.....»»
