Exploring the effects of exchange rate fluctuations on technological learning rates
When it comes to predicting the costs of new energy systems and technologies, researchers must consider learning rates, which are estimated measures of technological progress. In fact, technological advances are typically associated with higher technological...
Enhancing high-nickel layered oxide cathodes for lithium-ion batteries
Lithium-based batteries are used to power most existing electric vehicles, yet the amount of time they can keep a vehicle going before they need to be recharged is still somewhat limited. In the future, high-nickel layered oxide cathode materials could help to...
Using deep learning to predict parameters of batteries on electric vehicles
The batteries used to power electric vehicles have several key characterizing parameters, including voltage, temperature, and state of change (SOC). As battery faults are associated with abnormal fluctuations in these parameters, effectively predicting them is of...
Surface organometallic chemistry could open new paths for synthetic fuels and energy carriers
To convert hydrocarbons into fuel, the petrochemical industry currently relies primarily on heterogeneous catalysts, which in most cases contain active metal sites with poorly defined structures. In recent years, however, an area of study known as surface...
PixelGreen: A hybrid, green media wall for existing high-rise buildings
Researchers at Deakin University and the University of Hong Kong have recently designed a hybrid green architectural wall system for high-rise buildings that integrates a vertical micro-farm and a media screen. They presented this wall, called PixelGreen, in a paper...
A new water-splitting technique to generate clean hydrogen
Electrolytic hydrogen production entails the generation of hydrogen from water using electrical power, which should ideally come from renewable power sources such as sunlight and wind. Although this method of producing hydrogen could be a very promising solution for...
All-perovskite tandem solar cells with 24.8% efficiency
A team of researchers at Nanjing University in China and the University of Toronto in Canada have recently fabricated all-perovskite tandem solar cells (PSCs), a type of solar cell with a key perovskite structured component. These new solar cells, presented in a paper...
Addressing the obstacles preventing the commercialization of lithium-rich layered sulfides
Anionic redox chemistry is a fairly new research area that could pave the way for the development of more efficient lithium ion-battery cathode materials such as Li-rich layered oxides. So far, however, anionic redox chemistry approaches have been found to have...
Study projects scenarios for water use reduction in thermal power plants using satellite imagery
Water and energy are closely linked, as current electricity generation methods often require water, and extracting water typically consumes energy. This connection between water and energy, also known as the "water-energy nexus," has been the focus of several...
