A group of scientists from Russia, China, and the United States predicted and then experimentally obtained barium superhydrides' new unusual superconductors. The study was published in Nature Communications.
Proton-exchange membrane (PEM) fuel cells are an energy storage technology that will help lower the environmental footprint of transportation. These fuel cells make use of a chemical reaction known as oxygen reduction.
Sodium-ion batteries are regarded as a possible substitute for lithium batteries. However, the anodes, or the positively charged electrodes, that function well for lithium-ion batteries do not exhibit the same performance level for sodium-ion batteries.
For years, researchers have worked to repurpose excess atmospheric carbon dioxide into new chemicals, fuels and other products traditionally made from hydrocarbons harvested from fossil fuels.
With the rapid development of smart portable electronics and electric vehicles, the consumption of lithium resource will increase dramatically and the cost of lithium-ion batteries (LIBs) may increase significantly in the future. In addition, the shortage (0.0017 wt% in the earth's crust) and uneven crustal distribution of lithium also limit its further development and application.
Lithium-ion batteries play a crucial role in modern life, right from powering cell phones and laptops to the new holiday toys. However, there is a safety threat—the batteries can catch fire.
Natural gas produces comparatively lower amounts of pollutants such as carbon dioxide—a powerful greenhouse gas and the main contributor to climate change—and thus, it is the cleanest conventional fossil fuel source.
All-solid-state batteries—the next-generation batteries—can concurrently enhance the capacity and stability of present-day lithium batteries.
Researchers from the Tokyo Institute of Technology have recently produced an innovative material that exhibits special thermal expansion properties.
MTO process, which was first commercialized in 2010, is a catalytic process converting methanol, which is typically made from coal, natural gas, biomass, and CO2, over SAPO-34 zeolite catalyst. It's becoming one of the main streams for producing light olefins, including ethylene and propylene, from non-oil resources.
