Electrochemical oscillations during copper electrodissolution/passivation in trifluoroacetic acid induced by current interrupt method
(Corrosion Science, 2014)
Complex oscillatory behavior of electric current and electrode potential were observed during potentiodynamic anodic polarization of Cu in 1 M TFA, applying the current interrupt method for IR drop compensation. This ...
Surface morphology modifications of titanium based implant induced by 40 picosecond laser pulses at 266 nm
(Journal of Alloys and Compounds, 2010)
Surface modification of titanium based implant Ti6Al4V induced by an Nd:YAG laser operating at a wavelength of 266 nm, with pulses of 40 ps, is presented. It is shown that the laser beam at fluences 0.96J cm(-2) and 0.29J ...
Safe trapping of cesium into pollucite structure by hot-pressing method
(Elsevier, 2016)
A simple one-step method with direct thermal conversion at lower temperatures for preparing a stabile Cs-aluminsilicate phase, known as pollucite, is presented. Cs-exchanged form of Na, Ca-LTA type of zeolite (Cs-LTA) was ...
SBA-15 templated mesoporous carbons for 2,4-dichlorophenoxyacetic acid removal
(Chemical Engineering Journal, 2013)
The ordered mesoporous silica SBA-15 was synthesized and used as a template for obtaining mesoporous carbon replicas. Adsorptive removal of pesticide 2,4-dichlorophenoxyacetic acid (2,4-D) from aqueous solutions onto two ...
