UD's long-term monitoring shows 60 percent reduction in acidity of Delaware rain Several decades ago, precipitation in Delaware was among the most acidic in the country. Pollutants in the air reacted with rainwater to sprinkle sulfuric, nitric and carbonic acids onto the ground below, affecting crops and ecosystems statewide. The scientific consensus is that pollution controls enacted through the Clean Air Act Amendments in the 1990s and other measures have helped decrease the acidity...

Modern methods for mass production of biological agents and fine chemicals require precise control of pH. However within these systems it is not always possible to use traditional methods for measuring acidity and alkalinity. Biomed Central's open access journal BMC Biotechnology describes a new and user friendly method for measuring pH, which uses luminescent dual life-time referencing (DLR), to provide real-time characteristics of enzyme reactions. Industrial methods for manufacturing...

Sometimes, solutions for hard problems can turn out to be pretty basic. That's especially true for a team of researchers at the Office of Science's Brookhaven National Laboratory (Brookhaven Lab), where the solution for a hard problem they were working on turned out to be pretty basic . . . and also a bit acidic. The hard problem they were working on was how to store hydrogen fuel. Hydrogen gas (H2) is a clean and powerful fuel, but it's also extremely light, which makes it difficult and...

Some organisms already experiencing ocean acidification levels not predicted to be reached until 2100 A group of 19 scientists from five research organizations have conducted the broadest field study of ocean acidification to date using sensors developed at Scripps Institution of Oceanography, UC San Diego. The study, "High-Frequency Dynamics of Ocean pH: A Multi-Ecosystem Comparison," is reported in today's issue of the journal PLoS One. It is an important step toward understanding how...

Alongside antacids like Prilosec® and Nexium®, a new product, Puroast® Low Acid Coffee, may provide some relief this holiday season. Woodland, CA (PRWEB) November 04, 2011 The upcoming holiday season brings with it the traditional gift giving, travel to see family, savory food, hearty beverages and â“ âœholiday heartburnâ, that nasty reminder weâve had too much of a good thing.    But this...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
