New reliable method to capture carbon from ambient air

ornl-carbon-capture-1OAK RIDGE, US: Scientists at the Department of Energy’s Oak Ridge National Laboratory have found a simple, reliable process to capture carbon dioxide directly from ambient air, offering a new option for carbon capture and storage strategies to combat global warming. Initially, the ORNL team was studying methods to remove environmental contaminants such as sulphate, chromate or phosphate from water. To remove those negatively charged ions. Read More

Some catalysts give their own oxygen for reactions: Study

mit-catalysts-1MASSACHUSETTS, US: Chemical reactions that release oxygen in the presence of a catalyst, known as oxygen evolution reactions, are a vital part of the chemical energy storage processes, including water splitting, electrochemical carbon dioxide reduction, and ammonia production. The kinetics of this type of reaction are generally slow, but compounds called metal oxides can have catalytic activities that vary over several orders of magnitude. Read More

Fine art: painting tricks of 19th century revealed


PARIS, FRANCE: To paint quickly while creating brilliant texture and volume effects artists relied on the development of innovative gels. All the rage in the 19th century—and still in use today—these compounds modify the properties of the oil paints they are combined with. Now the researchers from Centre national de la recherche scientifique (CNRS), University Pierre and Marie Curie (UPMC), and College de France together have finally learned the chemical. Read More

Synthesizing sodium carbonate by solvay process


Sodium carbonate (Na2CO3) is found naturally or is manufactured from natural salt i.e., sodium chloride (common salt). It has many uses but, one of the major notable applications is in making of glass. Soda ash is a key chemical for producing soap, paper making, baking soda production, and bleaching fabrics and paper. The name “soda ash” is based on the principal historical method of obtaining alkali, which was by using water to extract it from ashes. The word “soda”. Read More
