Synthesis of pure and La-doped anatase nanopowders by sol-gel and hydrothermal methods and their efficiency in photocatalytic degradation of alprazolam
(Elsevier Ltd., 2014)
Pure and La3+ doped titanium dioxide (TiO2) nanopowders were obtained by sol gel and hydrothermal methods. A precursor was titanium tetrachloride and concentrations of dopants were 0.5 and 1.0 mol%. Procedures of both ...
A rapid test to measure adhesion between optical fibers and ethylene-vinyl acetate copolymer (EVA)
(Elsevier Sci Ltd, Oxford, 2016)
Optical fibers are transported on a drum and on some occasions it is essential to fix them and to keep them fixed to the drum. Adhesives are used in such situations to obtain the best and durable fixation. This research ...
