Advances in aluminum-air battery technology might allow electrically powered vehicles to become more realistic and competitive automotive options for many drivers.At present, most electric vehicles (EVs) are powered by lithium-ion battery packs and…

Recycling or reuse is in most instances environmentally preferable to disposal. Reuse of coal tar as an asphalt-pavement sealant for driveways and parking lots, however, has turned out to be an exception to this rule of thumb. Asphalt and asphaltite…

Over the next 10 to 20 years, capturing carbon dioxide (CO2)—a powerful greenhouse gas emitted from sources such as fossil-fuel-burning power plants, natural-gas processing plants, bioethanol plants, and cement plants—could become a significant…

Among the goals of organic synthesis are the high-yield production of target molecules with minimal unwanted by-products and the discovery of new molecules and new chemical reactions. In its simplest approach, organic synthesis is done in solution…

The very weak attractive forces between neutral atoms and molecules are known as van der Waals forces. These forces are important for holding molecules together and influencing materials properties such as boiling and melting points, solubility,…

Many parts of the world, particularly in poorer countries, need better tools for identifying unsafe drinking water. A test developed by researchers at the University of Bristol, United Kingdom, seems to show potential as a low-cost technique for…

Click chemistry is a method used in chemical synthesis and polymerization processes in which molecules are interlinked by reactive groups that will only connect with one another. Developed in the laboratory of K. B. Sharpless at The Scripps Research…

A new polymer has a molecular structure and physical properties very similar to those of lubricin, a protein that lubricates the opposing bone surfaces in moving (articulating) joints of the body. Chemistry researchers from the University of…
