Electrical engineers have taken the first steps in a project to develop fast-blinking LED systems for underwater optical communications. They show that an artificial metamaterial can increase the light intensity and 'blink speed' of a fluorescent light-emitting dye molecule.

If the chemical bonds that hold together the constituent atoms of a molecule could be tuned to become stronger or weaker, certain chemical properties of that molecule might be controlled to great advantage for applications in energy and catalysis. Researchers were able to accomplish this feat by using an applied voltage and electric current to tune the strength of chemical bonds in fullerene or 'buckyball' molecules.

When capturing images at the atomic scale, even tiny movements of the sample can result in skewed or distorted images - and those movements are virtually impossible to prevent. Now microscopy researchers at North Carolina State University have developed a new technique that accounts for that movement and eliminates the distortion from the finished product.
