his study demonstrates the feasibility of coastal water quality mapping using satellite remote sensing images. Water quality sampling campaigns were conducted over a coastal area in northern Taiwan for measurements of three water quality variables including Secchi disk depth, turbidity, and total suspended solids. SPOT satellite images nearly concurrent with the water quality sampling campaigns...

Applying Nanoporous Materials is an appropriate method for improving chemical quality of the water due to high surface area, internal porous structure (porosity), high absorption capability of harmful gases and liquids, and capability of reactivating the surface. Therefore, actions were carried out in order to investigate the effect of Activated carbon and Zeolite on reducing the total dissolve...

Non-water based fixed abrasive polishing was adopted to manufacture LBO crystal for nano precision surface quality because of its deliquescent. Ethyl alcohol was selected as the non-water based slurry solvent and ethanediamine, lactic acid, hydrogen peroxide was added in the slurry as a chemical additive, respectively. Effect of different additives with non-water based slurry on material remova...
