Fluoride Distribution and Related Health Problems
Abstract: Fluoride is one of the very few chemicals that cause significant effects in people depending upon their concentration. Although present naturally in soil, water and air, fluoride consumption occurs largely through water. Fluoride intake at low concentration is known to cause beneficial effects on teeth, however at high concentrations; it may give rise to a number of adverse effects. These range from mild dental fluorosis to crippling skeletal fluorosis as …

Nanocoating and Electrospraying Techniques Used for Corrosion Mitigation of Aluminum in Nitrogen dioxide Environment
Abstract: Nitrogen gas absorbs moist air to produce nitric acid. It develops acidic medium for aluminum. It forms a corrosion cell on the surface of aluminum. The formation of corrosion cell is written as: Al|Al+3||H+|H2 thus Corrosion reactions accelerate on aluminum surface and Al is oxidized into Al+3 and the H+ ions is reduced into H2. This acid produces various forms of corrosion in aluminum like galvanic, pitting, stress, crevice, blistering, …

Ultrasonic Study of Binary Liquid Mixtures of Triethyl Amine With Primary Alcohols at 303.15 K
Abstract: Most of the physical properties change whenever there is a change in the composition and structure of the liquid mixture. Then non-linear dependence of the physical–chemical properties with composition has been attributed to the size, shape, and polarity of the molecules. Ultrasonic velocity is one such property which is very important for the study of molecular interactions in solution. It gives information about the extent of interaction and some other …
