Grinding aids, strength enhancers and quality improvers are based on chemical products. Grinding aids work mainly by dispersing ground cement particles to avoid agglomerates, enabling an increase in production of up to 25 per cent. 1 In vertical roller mills, they can additionally be used to reduce vibrations and the amount of water injection, and thereby improve cement quality. 2

Photothermal therapy is a physical-chemical therapy for the treatment of cancer that employs optical radiation in the near-infrared (NIR) wavelength range (700-2000 nm). When a laser is focused on a tissue, the photons are absorbed by the intercellular and intracellular areas and the energy of the photons is converted into heat.

During 1893 and 1894, Lea published three more papers that extended his investigations of mechanical force on chemical bonds. First, he cranked up his static press to see what happened when he squashed 15 materials known to change color when decomposed by light or heat. Several of these decomposed under static pressure, to varying degrees.

The reaction of pyrochlore and carbon starts at 950°C and proceeds vigorously. After being heated to 1800—2000°C, the cooled friable mixture is acid-leached leaving an insoluble residue of carbides of niobium, tantalum, and titanium. These may be dissolved in HF or may be chlorinated or burned to oxides for further processing.
