EVOLUTION OF THE COPPER SURFACE IN THE COURSE OF OXIDATION BY CCl4–L (L=THF, DMF, DMSO): SCANNING PROBE MICROSCOPE STUDY

PANTELEEV, S. V.; MASLENNIKOV, S. V.; IGNATOV, S. K.; … - In: Surface Review and Letters (SRL) 20 (2013) 03, pp. 1350023-1

The evolution of compact surface of the 100 nm copper film deposited on the glass-ceramics doped with vanadium coating … roughness of copper films. The amount of the metal reacted has an almost linear dependence on the reaction time. AFM scans … indicate that there is the same mechanism of the reaction between copper and carbon tetrachloride for all solvents. …

INHIBITION EFFECT OF DODECYLAMINE ON CARBON STEEL CORROSION IN HYDROCHLORIC ACID SOLUTION

CHEN, ZHENYU; HUANG, LING; QIU, YUBING; GUO, XINGPENG - In: Surface Review and Letters (SRL) 19 (2012) 06, pp. 1250060-1

Dodecylamine spontaneously adsorbs on carbon steel via its polar group (-NH2) in hydrochloric acid solution. Furthermore, it forms a monolayer film on carbon steel surface. The inhibition mechanism of dodecylamine for carbon steel is geometric blocking effect. The adsorption of dodecylamine on...

Physico-chemical and mechanical properties of microencapsulated phase change material

Giro-Paloma, Jessica; Oncins, Gerard; Barreneche, Camila; … - In: Applied Energy 109 (2013) C, pp. 441-448

Microencapsulated phase change materials (MPCM) are well known in advanced technologies for the utilization in active and passive systems, which have the capacity to absorb and slowly release the latent heat involved in a phase change process. Microcapsules consist of little containers, which...
