UNTIL the development of the conception of hydrogen-ion concentration, the use of indicators was confined within more or less empirical boundaries. It is therefore only during comparatively recent ...

IT has been found possible to concentrate inorganic ions from aqueous solutions, even if very dilute, by a flotation technique. The principle depends upon the use, as a collector, of a surfactant ion, ...

Molarity is the concentration of a solution in terms of the number of moles of the solute in 1 dm 3 (1 liter) of the solution. What are the units of molarity? The units of molarity are M or mol/L. A 1 ...

Determining the number of copies of a double stranded DNA template (be it genomic DNA, plasmid or an amplified fragment) is essential for many genetic quantification applications in research and ...

Over the past year, millions of automotive enthusiasts and everyday drivers have taken to forums, communities, and expert platforms like AutoGuide to share their passion, ask questions, and exchange ...

The researchers from the Dalian Institute of Chemical Physics, affiliated with the Chinese Academy of Sciences, created an all-solid-state rechargeable hydride ion battery. This innovative design ...

Over-the-counter medications, topical pain relivers, and some natural ingredients may help temporarily relieve tooth pain. But seeing a dentist may be essential. Chewing, talking, and even sleeping ...

A hydrogen battery that operates at just 90 °C has been developed by researchers from Japan, overcoming the high-temperature and low-capacity limits of earlier methods. The device works by moving ...

One of the most pressing challenges facing the use of hydrogen is its storage, which typically requires extremely low temperatures (−252.8 °C) and high pressures (350 to 700 bar). Instead of storing ...
