Nanotech-powered electrodes help solve the challenges of using sweat to assess biological conditions in real time.

In conventional organic solar cells, the electrons exhibit their particle-nature and need to jump between organic molecules in the cell. The conductivity is, therefore, lower than that of crystalline silicon solar cells. Researchers have succeeded to arrange the organic molecules in highly ordered manner like in crystals and to invoke the wave-nature. 'Conductive bands' are formed by energy dispersive states and contribute to the high-carrier conductivity. It may improve the total efficiency of the cell.

As the world struggles to meet the increasing demand for energy, coupled with the rising levels of CO2 in the atmosphere from deforestation and the use of fossil fuels, photosynthesis in nature simply cannot keep up with the carbon cycle. But what if we could help the natural carbon cycle by learning from photosynthesis to generate our own sources of energy that didn't generate CO2?

A new class of coatings that sheds ice effortlessly from even large surfaces has moved researchers closer to their decades-long goal of ice-proofing cargo ships, airplanes, power lines and other large structures.

Extreme ocean winds and wave heights are increasing around the globe, with the largest rise occurring in the Southern Ocean, University of Melbourne research shows.
