Remineralisation of Reverse Osmosis (RO) Water Using Synthetic Aragonite
ABSTRACT Reverse osmosis (RO) treated water often requires remineralisation to restore Ca2+ ions, hardness and alkalinity, particularly for potable water. This study compares the dissolution characteristics of two forms of calcium carbonate, aragonite and calcite.

Production of Si3N4 porous beads via carbothermal reduction and nitridation technique
Si3N4 porous beads were produced from direct carbothermal reduction and nitridation of spheres composed of carbon+SiO2 mixtures. A simple one–step sol–gel templating technique was used to prepare carbon+SiO2 (molar ratio of carbon/SiO2 was set as 4 ...

Corrosión atmosférica de metales en condiciones climáticas extremas
This paper analyses the influence of extreme climatic conditions on the atmospheric corrosion of metals. This corrosion phenomenon is determined mainly by the time that moisture is retained on the metallic surface (time of wetness), the presence of ...
