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...

Los Alamos team sees unprecedented proof of ion's role in enzymatic process A Los Alamos National Laboratory research team has harnessed neutrons to view for the first time the critical role that an elusive molecule plays in certain biological reactions. The effort could aid in treatment of peptic ulcers or acid reflux disease, or allow for more efficient conversion of woody waste into transportation fuels. In a paper appearing this week in Angewandte Chemie International Edition, Los Alamos...

Studies of the probable role of organic acids in lakes indicate that power plant emissions may have had a smaller impact on lake acidity than previously assessed During the 1970s and 1980s, researchers and policymakers became increasingly worried about multiple consequences of acidic emissions of sulfur dioxide and nitrogen oxides from the stacks of power stations, and eventually they were controlled. In Europe, there was much concern about the effects on Sweden's many lakes, which were found...

A simple cut to the skin unleashes a complex cascade of chemistry to stem the flow of blood. Now, scientists at Washington University School of Medicine in St. Louis have used evolutionary clues to reveal how a key clotting protein assembles. The finding sheds new light on common bleeding disorders. The long tube-shaped protein with a vital role in blood clotting is called von Willebrand Factor (VWF). Made in cells that form the inner lining of blood vessels, VWF circulates in the blood...

Ocean Acidification
2013-04-01 10:32:20

Ocean acidification is the name that was given to the ongoing decrease in the pH of Earth’s oceans, a cause of the uptake of anthropogenic carbon dioxide from the atmosphere. About 30 to 40 percent of the carbon dioxide that is released by humans into the atmosphere dissolves into the lakes, oceans, and rivers. To maintain the chemical equilibrium, some of it reacts with the water to create carbonic acid. Some of these extra carbonic acid molecules react with a water molecule to provide a...

A pH meter, typically consisting of a special measuring probe connected to an electronic meter, is an electronic instrument used to measure the pH (acidity or alkalinity) of a liquid. The probe measures pH as the hydrogen ion activity that surrounds a thin-walled glass bulb at its tip. A small voltage is produce by the probe that measures and displays pH units by the meter. The meter circuit displays voltmeter in pH units instead of volts. The circuit of the pH meter consists of operational...
