The year of 2023 was the hottest on record, with the increase in Earth's surface temperature nearly crossing the critical threshold of 1.5 degrees Celsius, EU climate monitors said Tuesday.
Improving soil health with aeration curing for sludge management
2024-01-09 22:45:33
The construction industry is recognized for its high resource consumption and large waste generation. Among the waste products generated are construction-generated sludge (CGS) and construction-generated surplus soil (CGSS). These can be used for various applications such as backfilling, creating environmentally friendly building materials like bricks, and soil stabilization.

2024-01-09 22:45:33
A team of researchers from Xidian University in China has achieved a new result in the field of microwave power transmission. Their study, published in Engineering, introduces an optimal design method for antenna aperture illumination with an annular collection area, with the goal of maximizing the power radiated on the collection area.
Green wheels, bright skies: New analysis unveils the connection between electric vehicles and photovoltaics
2024-01-09 22:45:33
People who own electric vehicles (EVs) are more likely to go a step further and add solar panels to their home, according to an analysis of a behavioral study by researchers at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL). Conversely, the impact of owning solar panels also has a bearing on whether a homeowner buys an electric vehicle but not as strongly.

Unique framework of tin bimetal organic compound facilitates stable lithium-ion storage
2024-01-09 22:00:43
Battery capacity is one of the primary bottlenecks in efficient renewable energy storage and significant reductions in carbon emissions. As a battery anode that releases electrons in a lithium-ion battery (LIB), tin (Sn) and Sn-mixture alloys could theoretically store more energy at a higher density than more common carbon-based anodes.
