Since their invention in 1962, semiconductor diode lasers have revolutionized communications and made possible information storage and retrieval in CDs, DVDs and Blu-ray devices. These diode lasers use inorganic semiconductors grown in elaborate high vacuum systems. Now, a team of researchers from Penn State and Princeton University have taken a big step toward creating a diode laser from a hybrid organic-inorganic material that can be deposited from solution on a laboratory benchtop.

Scientists from ITMO University have suggested a new solar cell coating that combines features of an electrode and those of a light-trapping structure. The coating enabled researchers to cut down on reflected light and avoid solar cell overheating, thus increasing its overall efficiency by 20 percent. Moreover, the suggested method may be attractive for industrial applications due to its relatively low cost and simplicity. The results of the research were published in Optics Letters.

With concerns over moving to a clean energy platform worldwide with electric vehicles and renewables, wasted energy is a factor as important as the amount of green energy produced. Thus, solid-state lighting based upon light-emitting diodes (LEDs) is touted as a solution. However, LEDs struggle to deliver high brightness for the shorter-wavelength end of lighting needs. And emitted short wavelengths facilitate white light through known phosphor downconverters.

Red-sensitive, blue-sensitive and green-sensitive color sensors stacked on top of each other instead of being lined up in a mosaic pattern – this principle could allow image sensors with unprecedented resolution and sensitivity to light to be created. However, so far, the reality hasn't quite met expectations. Researchers from Empa and ETH Zurich have now developed a sensor prototype that absorbs light almost optimally – and is also cheap to produce.

Just as mechanical properties and chemical compositions of materials are of fundamental importance in buildings, the cells that comprise every living organism have different properties and shapes depending on their function and state. Uncontrolled modifications in cell elasticity, or in the elasticity of any biological tissue in general, are symptoms and effects of pathologies—hardened coronary arteries causing heart problems, weakened bones inducing orthopedic complications, elastic changes in corneal tissue provoking ocular pathologies, etc. A non-invasive experimental technique that can probe in-situ the elastic and the biochemical properties of cells and tissues would be a strategic diagnostic tool.
