When our cells' acid-alkaline balance goes wrong, it can go wrong in a big way -- think cancer and cystic fibrosis. New fluorescent probes make it easier to detect pH and sweetened the deal by adding ...

When Arnold Beckman, a professor of analytical chemistry at the California Institute of Technology, was asked to devise a way to measure acidity in citrus fruit, the resulting “acidometer” ...

In coal-fired power plants, measurement and control of pH is critical to the efficient operation of wet flue gas scrubbers. However, harsh process conditions can necessitate frequent cleaning and ...
