Photoluminescence properties of Er3+-doped 70TeO2–30ZnO glasses are investigated. Infrared to visible upconversion has been observed at room temperature in this tellurite glass using a 797 nm excitation laser. A study of the 4S3/2 → 4I15/2 and 4F9/2 → 4I15/2 transitions versus excitation laser power shows evidence for…

Fungal influenced corrosion is reviewed for carbon steel and aluminum fuel tanks; carbon steel cables; and painted and unpainted ship holds containing wet and dry cargos, including wood, molasses, fatty oils and cereal. Deterioration of fiber-reinforced composites and glass has also been attributed to fungal species.

Abstract The physicochemical properties of clays can be modified by acid treatment with inorganic acids. This treatment is usually referred to as ‘acid activation’, because it increases the specific surface area and the number of active sites of the solids. In the present study, the acid activation of saponite from Ce…
