adminThe inventor of the lithium-ion battery, and his team of researchers, have identified a new cathode material made of the nontoxic and inexpensive mineral eldfellite for sodium-ion batteries.
Researchers have borrowed from biological structures called tubercles that humpback whales use to maneuver in the ocean to make a piezoelectric energy harvester for use as an airflow or fluid speed and direction-sensing device.
adminAn international team of researchers has taken a step toward achieving controlled nuclear fusion — a process that powers the sun and other stars, and has the potential to supply the world with limitless, clean energy. The team developed a new technique to ‘see’ where energy is delivered during fast ignition experiments and improve energy delivery to the fuel target.
The battery is the heart of the electric car. Researchers have developed an energy storage device which is significantly more cost-effective over the entire life cycle in comparison with previous models. If one of the more than one hundred battery cells is defective, it can be replaced easily. Until now, the entire battery had to be replaced.
adminIn the quest for sustainable alternative energy and fuel sources, one viable solution may be the conversion of the greenhouse gas carbon dioxide into liquid fuels, say scientists.
adminAn inexpensive method for generating clean fuel is the modern-day equivalent of the philosopher’s stone. One compelling idea is to use solar energy to split water into its constituent hydrogen and oxygen and then harvest the hydrogen for use as fuel. But splitting water efficiently turns out to be not so easy.
adminStacking two solar cells one over the other has advantages: Because the energy is ‘harvested’ in two stages, and overall the sunlight can be converted to electricity more efficiently. Researchers have come up with a procedure that makes it possible to produce thin film tandem solar cells in which a thin perovskite layer is used. The processing of perovskite takes place at just 50 degrees Celsius and such a process is potentially applicable for low cost roll-to-roll production in future.
