(PhysOrg.com) -- In yet another novel use for graphene, researchers from Seoul University have devised a method of creating transparent loudspeakers by printing them onto a special kind of plastic, using an ordinary inkjet ...
Chemists normally work rigorously to exclude impurities from their reactions. This is especially true for scanning tunneling microscopy (STM) experiments that can produce atomic-scale images of surfaces. Using STM to investigate ...

(PhysOrg.com) -- Japanese researchers, led by Masashi Kawasaki, have discovered that a previously known kind of double layered material created using electrostatic doping can be used as a superconductor.
Researchers at the Stanford University School of Medicine have taken a machine already in use for the measurement of impurities in semiconductors and used it to analyze immune cells in far more detail than has been possible ...
