Johnny heath corpus christi Affordable Hydrogen Fuel Cells News Promising technique improves hydrogen production of affordable alternative to platinum

Scientists have demonstrated that microwaves can help create nanostructured molybdenum disulfide (MoS2) catalysts with an improved ability to produce hydrogen. The microwave-assisted strategy accomplishes this by increasing the space, and therefore decreasing the interaction, between individual layers of MoS₂ nanosheets.

Johnny heath corpus christi Affordable Hydrogen Fuel Cells News Chemists find better way to pack natural gas into fuel tanks

Increasing numbers of natural gas-powered trucks and buses are hitting the road, but a major disadvantage is the bulky equipment needed to store compressed NG or to keep liquefied NG cold. Now chemists have developed an innovative new storage material for methane that could lessen the hassle of filling up with NG, and extend the range of such vehicles. The material is a flexible metal organic framework that expands when methane is pumped in.

Johnny heath corpus christi Affordable Hydrogen Fuel Cells News Faster design, better catalysts

While the cleaning of car exhausts is among the best known applications of catalytic processes, it is only the tip of the iceberg. Practically the entire chemical industry relies on catalytic reactions. Therefore, catalyst design plays a key role in improving these processes. An international team of scientists has now developed a concept, that elegantly correlates geometric and adsorption properties. They validated their approach by designing a new platinum-based catalyst for fuel cell applications.

Johnny heath corpus christi Affordable Hydrogen Fuel Cells News Extending a battery's lifetime with heat

Over time, the electrodes inside a rechargeable battery cell can grow tiny, branch-like filaments called dendrites, causing short circuits that kill the battery or even ignite it in flames. But thanks to new experiments and computer simulations, researchers have explored in detail how higher temperatures can break down these dendrites -- and possibly extend battery lifetimes.
