Next-generation solar cells that mimic photosynthesis with biological material may give new meaning to the term 'green technology.' Adding the protein bacteriorhodopsin (bR) to perovskite solar cells boosted the efficiency of the devices in a series of laboratory tests, according to an international team of researchers.
Read moreScientists have developed a forensic tracer that uses lead isotopes to detect and measure coal fly ash in dust, soil and sediments. Tests show the new tracer can distinguish between the isotopic signature of lead derived from coal ash and lead that comes from other major human or natural sources. Exposure to fly ash from dust, soil or sediments has been linked to numerous diseases and health concerns.
Read moreThe transition from coal to natural gas in the US electricity sector is reducing the industry's water use, research finds. For every megawatt of electricity produced using natural gas instead of coal, the water withdrawn from rivers and groundwater drops by 10,500 gallons, and water consumed for cooling and other plant operations and not returned to the environment drops by 260 gallons. Switching to solar or wind power could boost these savings even more.

A widely-used gas that is currently produced from fossil fuels can instead be made by an 'artificial leaf' that uses only sunlight, carbon dioxide and water, and which could eventually be used to develop a sustainable liquid fuel alternative to gasoline.
Fluctuations in atmospheric pressure can heavily influence how much natural gas leaks from wells below the ground surface at oil and gas sites, according to new research. However, current monitoring strategies do not take this phenomenon into account, and therefore may be under- or over-estimating the true magnitude of gas emissions.
Read moreScientists have conducted an in-depth study on how carbon nanotubes with oxygen-containing groups can be used to greatly enhance the performance of perovskite solar cells. The newly discovered self-recrystallization ability of perovskite could lead to improvement of low-cost and efficient perovskite solar cells.
Read moreA research group has developed an efficient process for breaking down any plastic waste to a molecular level. The resulting gases can then be transformed back into new plastics – of the same quality as the original. The new process could transform today's plastic factories into recycling refineries, within the framework of their existing infrastructure.

Read moreScientists investigated a material that uses sunlight for splitting water molecules (H2O) to obtain dihydrogen (H2). Since dihydrogen can be used as clean fuel, this study provides relevant insight for researchers dealing with clean energy generation.
Read moreResearchers have modeled the fluid dynamics of multi-rotor wind turbines via high-resolution numerical simulations. The simulations demonstrate a clear advantage for a turbine model with four rotors. The researchers found, that the wind turbine wake recovers much faster with multi-rotor turbines, that multi-rotor turbines produce slightly more energy than single-rotor turbines, and that a turbine with four rotors as far apart as possible is the optimal construction.
