Johnny heath corpus christi Affordable Hydrogen Fuel Cells News Researchers peel back another layer of chemistry with 'tender' X-rays

Scientists can now directly probe a previously hard-to-see layer of chemistry thanks to a unique X-ray toolkit. A key breakthrough enabling the latest experiment was in tailoring “tender” X-rays—which have an energy range tuned in a middle ground between the typical high-energy (or “hard”) and low-energy (or “soft”) X-rays used in research—to focus on chemistry within the double layer of a sample electrochemical system.

Johnny heath corpus christi Affordable Hydrogen Fuel Cells News Flywheel technology could create new savings for light rail transit

Two engineering professors have examined the use of flywheel technology to store energy generated when light rail transit trains decelerate and stop. Trains such as the LRT used in Edmonton, Alberta, Canada, are designed with so-called dynamic braking. The deceleration generates electrical energy, which needs to go somewhere.A flywheel system could store it as mechanical energy. This energy could be converted to electrical energy when the train is ready to leave the station.

Johnny heath corpus christi Affordable Hydrogen Fuel Cells News Development of Silicon-Metal Composite Material for High Capacity Lithium-Ion Rechargeable Batteries

A research group have developed an anode material for lithium (Li)-ion rechargeable batteries by forming nanoparticles made of silicon (Si)-metal composites on metal substrates. The resulting anode material had high capacity - almost twice as high as conventional materials - and a long cycle life. These results will lead to the development of higher-capacity, longer-life anode materials for Li-ion rechargeable batteries.

Johnny heath corpus christi Affordable Hydrogen Fuel Cells News Scientists solve puzzle of converting gaseous carbon dioxide to fuel

Every year, humans advance climate change and global warming by injecting about 30 billion tons of carbon dioxide into the atmosphere. Scientists believe they've found a way to convert all these emissions into energy-rich fuel in a carbon-neutral cycle that uses a very abundant natural resource: silicon. Readily available in sand, it's the seventh most-abundant element in the universe and the second most-abundant element in the earth's crust.
