Scientists 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 moreScientists have found a new compound of plutonium with an unexpected, pentavalent oxidation state. This new phase of plutonium is solid and stable, and may be a transient phase in radioactive waste repositories.
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 moreThe art of croissant making has inspired researchers to find a solution to a sustainable energy problem.
Read moreAs global temperatures continue to rise, the thawing of permafrost is accelerated and mercury trapped in the frozen ground is now being released. The mercury is transforming into more mobile and potentially toxic forms that can lead to environmental and health concerns for wildlife, the fishing industry and people in the Arctic and beyond.
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.
Read moreNew method allows scientists to create a quantitative map of radioactive cesium-rich microparticle distribution in soils collected around the damaged Fukushima Daiichi Nuclear Power Plant Nuclear Power Plant (FDNPP). This could help inform clean-up efforts in Fuksuhima region.
Read moreScientists have estimated the emissions intensity of carbon dioxide and other air pollutants from a major electricity distributor and highlighted key consequences – essential information for policymakers shaping decisions to reduce electricity system emissions.
Read moreScientists have developed a device that can identify a wide range of airborne gases and chemicals instantly.
Read moreHumans are diurnal — we are active in the day and sleep at night. But diurnalism is by far the exception rather the rule in mammals. About 250-230 million years ago, the mammalian ancestors, called the therapsids, became exclusively nocturnal, and stayed so until the demise of the dinosaurs 66 million years ago.
