Electronic self-passivation of single vacancy in black phosphorus

NUS scientists discovered that a two-dimensional (2D) semiconducting material, known as black phosphorus (BP), exhibits an electronic self-passivation phenomenon by re-arranging its vacancy defects. This may potentially enhance ...

Graphene sensor rapidly detects opioid metabolites in wastewater

The unique properties of the atom-thick sheet of carbon, known as graphene, enabled a new penny-sized, multiplexed bio-sensor that's the first to detect opioid byproducts in wastewater, a team of researchers from Boston College, ...

Biosensors using field-effect transistors show great promise

Demand for sensitive and selective electronic biosensors—analytical devices that monitor a target of interest in real time—is growing for a wide range of applications. They are ideal for health care within clinical settings, ...

Imaging technique reveals strains and defects in vanadium oxide

Researchers led by Edwin Fohtung, an associate professor of materials science and engineering at Rensselaer Polytechnic Institute, have developed a new technique for revealing defects in nanostructured vanadium oxide, a widely ...
