Curbing diesel emission could reduce big city mortality rate

US cities could see a decline in mortality rates and an improved economy through midcentury if federal and local governments maintain stringent air pollution policies and diminish concentrations of diesel freight truck exhaust, according to new research.

Using high energy density material in electrode design enhances lithium sulfur batteries

To develop higher capacity batteries, researchers have looked to lithium sulfur batteries because of sulfur’s high theoretical capacity and energy density. But there are still several problems to solve before they can be put into practical applications. The biggest is the shuttling effect that occurs during cycling. To solve this problem and improve lithium sulfur battery performance, the researchers created a sandwich-structured electrode using a novel material that traps polysulfides and increases the reaction kinetics.

Gas station shuts down pumps, goes all-in on electric-vehicle charging

Old Gas PumpsThe owner of a 60-year-old fueling station in Maryland disconnected from the legacy of Big Oil and went all-electric, partnering with the Electric Vehicle Institute and the state energy administration to rip out the gas pumps and install chargers. Depeswar Doley of RS Automotives in Takoma Park told CNBC that he was tired of the way oil companies…

Converting CO2 to valuable resources with the help of nanoparticles

An international research team has used nanoparticles to convert carbon dioxide into valuable raw materials. Scientists have adopted the principle from enzymes that produce complex molecules in multi-step reactions. The team transferred this mechanism to metallic nanoparticles, also known as nanozymes. The chemists used carbon dioxide to produce ethanol and propanol, which are common raw materials for the chemical industry.
