New discoveries in chemistry include a special coating for roof tiles that reduces air pollution, the ability to provide information regarding the dangers of sewer gases and improvements in food storage options. New discoveries continue to improve human life and protect the environment.Know More
Chemists have recently developed a special titanium dioxide coating for roof tiles which breaks down nitrogen oxide and reduces air pollution. The amount of nitrogen oxides broken down annually is equal to the amount an automobile produces driving 11,000 miles. According to ScienceDaily, the cost of titanium dioxide to treat an average home is about $5.
Another advancement in chemistry involves chemical analysis of sewer gas to determine the condition of sewer pipes. As pipelines begin to deteriorate, the gases emitted contain more sulfur dioxide and are more uniform in nature. This knowledge can warn maintenance teams as to when they should look for developing problems to be able prevent contamination of surface and ground water.
Chemistry also continues to improve food storage alternatives. ScienceDaily reports that use of essential oils from oregano and cloves in plastic wrap helps to retard the growth of mold and bacteria in bread. When bread that contains the commonly used calcium propionate is stored in normal plastic bags, the preservative loses its effectiveness after 10 days. However, bread stored in edible films made with these essential oils continues to remain fresh for a much greater period.Learn more about Chemistry
The Kp in the study of chemistry is an equilibrium constant of both heterogeous and homogeneous gaseous reactions, according to ChemGuide. Value is determined by the partial pressures of the gases inside a closed system.Full Answer >
Chemistry articles consist of a collection of written narratives about chemistry or chemicals. Major publications, magazines and scholarly journals publish chemistry articles with information targeted toward educators, scientists and chemists, as well as the general public.Full Answer >
In chemistry, the constant R stands for the universal gas constant. R is equal to 8.31 joules per mole-Kelvin or 0.08 liter-atmospheres per mole-Kelvin. It is the expression of the Boltzmann constant, k, in units of energy.Full Answer >
Chemistry improves almost all aspects of people's lives either directly or indirectly; advances in chemistry have led to life-saving medicine, improvements to the way humans treat their environment, sources of green energy and other useful technologies. Chemistry is often referred to as the "central science" because of its role in connecting and advancing disparate fields, and its effects on people's lives reflect its diverse applications.Full Answer >
