A first-of-its kind inhalable measles vaccine for developing countries, where the disease remains a scourge. A "nanogenerator" that could recharge iPods and other electronic devices with a shake. And for Fido and Fluffy, a long-awaited once-a-month pill for both ticks and fleas.It's list season, the time to prepare inventories of what stood out in 2009 and holds promise for the year ahead. Those three advances are among more than 250 research advances publicized in 2009 by the...
New insight into how nature handles some fundamental processes is guiding researchers in the design of tailor-made proteins for applications such as artificial photosynthetic centers, long-range electron transfers, and fuel-cell catalysts for energy conversion.From rusting iron to forest fires to the beating of a human heart, oxidation-reduction reactions, which transfer electrons from one atom to another, are at the heart of many chemical and biological processes. Each process requires a...
Physicists, chemists and engineers at the University of Pennsylvania have demonstrated a novel method for the controlled formation of patchy particles, using charged, self-assembling molecules that may one day serve as drug-delivery vehicles to combat disease and perhaps be used in small batteries that store and release charge.Researchers demonstrated that the positive electrical charges of calcium ions "” just like the calcium in teeth and bone "” can form bridges between negatively...
Company Must Properly Clean Up Susquehanna County Gel Spill WILLIAMSPORT, Pa., Sept. 22 /PRNewswire-USNewswire/ -- The Department of Environmental Protection has issued a notice of violation to Cabot Oil and Gas for two liquid gel spills last week at the company's Heitsman natural gas well pad in Dimock Township, Susquehanna County, which polluted a wetland and caused a fish kill in Stevens Creek. "DEP is very concerned about spills at Cabot sites and will require Cabot to take all...
While our standard of life increases, so does the worldwide energy demand. In this vein, the application of technologies based on fuel cells is put forward as an alternative to the massive consumption of fossil fuels. One of the fuel cells of greatest current interest is the solid oxide one.The PhD thesis by researcher at the University of the Basque Country (UPV/EHU), Ms Ana MartÃnez Amesti, focused on optimizing solid oxide fuel cells, one of the most promising technologies of the future...
Temperature determines which molecule rocks outScientists have long known that molecules dance about as the temperature rises, but now researchers know the exact steps that water takes with a certain molecule. Results with small, electrically charged cyanide ions and water molecules reveal that water zips around ions to a greater extent than expected. The findings improve our understanding of a chemical interaction important in environmental and atmospheric sciences."One of the...
Australian scientists say they have determined pollution from Asia, Europe and North America is causing climate change in the Southern Hemisphere. Researchers at Australia's Commonwealth Scientific and Industrial Research Organization said they used a climate model that included the effects of tiny particles called aerosols produced primarily in North America. The study, led by Leon Rotstayn, principal scientist at the Center for Australian Weather and Climate Research, suggests aerosols can...
SEATTLE, July 28 /PRNewswire-FirstCall/ - Mantra is pleased to announce that it has observed an increase in current efficiency in its Electroreduction of Carbon Dioxide (ERC) technology through the use of a new proprietary electrode catalyst structure. This is just the first of a series of improvements expected by Mantra as they progress through a series of development trials. John Russell, Mantra's Vice President, Technology Evaluation, comments: "As a part of our latest development...
NORTH LIBERTY, Iowa, June 15 /PRNewswire/ -- Bio-Research Products announced today the first commercial, plant-based diamine oxidase (DAO). Dr. Bryce Cunningham, President and Chief Technology Officer of Bio-Research, reports that this new diamine oxidase is orders of magnitude more active than DAO derived from pig kidney tissue. The enzyme is available as a lyophilized powder. Price will be $200 per kilounit. Diamine Oxidase is useful for test assays to detect spoilage by the presence of...

Chemistry is a physical science concerned with the composition, structure, and properties of matter. It also deals with the changes that matter undergoes during chemical reactions. It incorporates the studies of various atoms, molecules, crystals and other aggregates which can be combined or isolated and concepts of energy and entropy through which chemical processes occur. Modern chemistry (from the Egyptian kēme, meaning "earth") evolved from alchemy following the chemical revolution...
In chemistry, salt is a general term used for ionic compounds composed of positively charged cations and negatively charged anions, so that the product is neutral and without a net charge. These ions can be inorganic (Cl-) as well as organic (CH3-COO-) and monoatomic (F-) as well as polyatomic ions (SO42-). Solutions of salts in water are called electrolytes. Electrolytes as well as molten salts conduct electricity. Zwitterions are salts that contain an anionic center and a cationic...
