A breakthrough in atomic-scale X-ray imaging, detecting the presence of just a few hundred gallium atoms inside an otherwise pure silicon crystal, is being celebrated at the University of Surrey.
The plant at Upper Myong Chu will generate 12 MW of electricity, while the Lower Myong Chu facility will create 06 MW which will increase Kundan Green Energy’s hydropower generation to over 50 MW in Sikkim, , Kundan Green Energy, hydropower, sikkim

UPTON, NY A team of researchers led by chemists at the U.S. Department of Energy s (DOE) Brookhaven National Laboratory has studied an elusive property in cathode materials, called a valence gradient, to understand its effect on battery performance. The findings, published in
Nature Communications, demonstrated that the valence gradient can serve as a new approach for stabilizing the structure of high-nickel-content cathodes against degradation and safety issues.
High-nickel-content cathodes have captured the attention of scientists for their high capacity, a chemical property that could power electric vehicles over much longer distances than current batteries support. Unfortunately, the high nickel content also causes these cathode materials to degrade more quickly, creating cracks and stability issues as the battery cycles.
