MIT researchers improve efficiency of quantum-dot photovoltaic system by adding a forest of nanowires Photovoltaics based on tiny colloidal quantum dots have several potential advantages over other approaches to making solar cells. But there’s a tradeoff in designing such devices because of two contradictory needs for an effective PV: A solar cell’s absorbing layer needs…

These color-enhanced scanning electron microscope images show nanosheets resembling tiny rose petals. The nanosheets are key components of a new type of biosensor that can detect minute concentrations of glucose in saliva, tears and urine. The technology might eventually help to eliminate or reduce the frequency of using pinpricks for diabetes testing. (See second story…
