Can Switzerland, as planned, cut its CO2 emissions to zero by 2050? In a study, researchers at the Paul Scherrer Institute PSI have investigated what measures would be necessary to achieve this reduction and how much it might cost per person.
The capacity of lithium-ion batteries decreases over time partly due to the degradation of the binder that protects the graphite anode. To address this problem, scientists from the Japan Advanced Institute of Science and Technology are investigating a new copolymer binder that can preserve the capacity of the anode at 95% of its original value even after >1700 charge cycles. Their findings can significantly enhance battery life for electric vehicles, artificial organs, and consumer electronics.
Professor Byoungwoo Kang develops a high-density cathode material through controlling local structures of the Li-rich layered materials.
Federal and state governments auction leases to oil and gas companies to extract natural resources from public land. A revamp of the auction system -- utilizing a new model developed by a Rice University economist -- could lead to more competitive bids and, ultimately, more money for governments.
Researchers led by Iowa State's Hui Hu took their studies of wind-turbine icing out of the lab and into the field to learn how and where ice accumulates on rotating blades. They learned ice on the blades can reduce power production by up to 80%. The field experiments also validated their experimental findings, theories and predictions.
COSMIC, a multipurpose X-ray instrument at Berkeley Lab's Advanced Light Source, has made headway in the scientific community since its launch less than 2 years ago, with groundbreaking contributions in fields ranging from batteries to biominerals.
New research finds that people are more engaged with reducing carbon emissions than previously thought - and that governments, scientists and companies should listen to them. The Nature Energy study investigates how invested people are in making the changes needed to reduce carbon emissions and stop climate change. It shows that people, their views and actions should be included more when it comes to how we transform the way we use energy, to keep global average temperatures well below 2°C.
An estimated 931 million tonnes of food, or 17% of total food available to consumers in 2019, went into the waste bins of households, retailers, restaurants and other food services, according to UNEP's Food Waste Index Report 2021. Conducted to support global efforts to halve food waste by 2030, the report presents the most comprehensive food waste data collection, analysis and modelling to date, and offers countries a methodology to measure their food waste problem.
The models used to produce global climate scenarios may overestimate the energy and emission savings from improved energy efficiency, warns new research led by academics at the University of Sussex Business School and the University of Leeds.
We report significantly enhanced photocurrents in the all-inorganic 2D perovskite Cs2PbI2Cl2, achieving over 3 orders of magnitude increase at the industrially achievable level of 2 GPa in comparison with its initial photocurrent.
