A new study puts us closer to do-it-yourself spray-on solar cell technology—promising third-generation solar cells utilizing a nanocrystal ink deposition that could make traditional expensive silicon-based solar panels a thing of the past.
adminEthanol gas stations are popping up all over as more people become interested in running their cars on ethanol. Indeed, many people already use ethanol and don’t realize it because…
adminThe Francis turbine is the most common type of water turbine used in Norwegian hydropower plants, and has been for many years. About half of the world’s Francis turbines are found in Norwegian plants.
Using a new procedure researchers can now produce extremely thin and robust, yet highly porous semiconductor layers. A very promising material — for small, lightweight, flexible solar cells, for example, or electrodes improving the performance of rechargeable batteries.
In a recent experiment, scientists were able to produce stable crystallized lithium superoxide instead of lithium peroxide during battery discharging. Unlike lithium peroxide, lithium superoxide can easily dissociate into lithium and oxygen, leading to high efficiency and good cycle life.
adminHitachi, Ltd. and Tohoku University’s Advanced Institute for Materials Research have developed a basic technology to reduce the internal resistance of the all-solid-state lithium ion battery using a complex hydride as a solid electrolyte.
adminAre wind farms harmful to humans? This controversial topic makes emotions run high. To give the debate more objectivity, an international team of experts dealt with the fundamentals of hearing in the lower limit range of the audible frequency range (i.e., infrasound), but also in the upper limit range (i.e., ultrasound).
