    Wind energy can deliver vital slash to global warming

    Implementing advance wind energy scenarios could achieve a reduction in global warming atmospheric average temperatures of 0.3 to 0.8 degrees Celsius by the end of the century, according to new research from Cornell University. “Early action will reap dividends,” said Rebecca Barthelmie, professor in the Sibley School of Mechanical and Aerospace Engineering. “In terms of […]

    Combining perovskite with silicon, solar cells convert more energy from sun

    Many countries around the world are committed to reducing emissions or reaching net-zero emissions to meet the United Nations’ climate goals of maintaining temperature increases below 1.5 degrees Celsius by 2050. Renewable energy technologies, particularly solar energy panels, will play a significant role in achieving these goals. To fully harness the potential of sunlight, scientists […]

    identify and clear efficiency hurdle for organic solar cells.

    The international group of researchers, led by the University of Cambridge, identified a loss pathway in organic solar cells which makes them less efficient than silicon-based cells at converting sunlight into electricity. In addition, they identified a way to supress this pathway by manipulating molecules inside the solar cell to prevent the loss of electrical […]

    Nano-scale discovery to cool down overheating in electronics.

    When you shrink down to very small scales, heat doesn’t always behave the way you think it should. Now, new findings from the nano realm could help researchers to gain a better handle on the flow of heat in electronic devices. A team of physicists at CU Boulder has solved the mystery behind a perplexing […]

    New ergonomic photodetector for the trillion-sensor era

    Light-to-frequency conversion circuits (LFCs) are often used to overcome setbacks faced by conventional ultra-low power light sensors. However, use of LFCs can lead to chip area wastage and poor performance of photosensors. Researchers have now developed a highly photosensitive LFC with improved chip area economy, high tuneability, and superior compatibility with flexible electronics. This novel […]

    Unusual material could improve the reliability of electronics and other devices

    Scientists have invented a new way to funnel heat around at the microscopic level: a thermal insulator made using an innovative technique. They stack ultra-thin layers of crystalline sheets on top of each other, but rotate each layer slightly, creating a material with atoms that are aligned in one direction but not in the other. The […]

    Iraq to build eight nuclear power plants with Russia’s help

    The Iraqi government plans to build eight nuclear power plants with the cooperation of Russia, costing over $40 billion, in order to overcome the challenges of electricity shortages in the country. The ‘Times’ of England in its report on the Iraqi project for constructing eight nuclear power plants wrote that this Arab country holds 8.4 […]
