Development and corrosion behaviour (Electrochemical Polarization Method) of aluminium alloy (LM-13) reinforced with Nano-ZrO2 chilled metal matrix composites (CNMMCs)

This paper presents the results obtained and the discussion made from a series of corrosion experiments involving aluminum alloy (LM 13) reinforced with Nano-ZrO2, size of the particles dispersed varies from 100 to 200 nm and amount of addition varies from 3 to 15 wt.% in steps of 3 wt.%. The resulting CNMMCs are solidified under the influence of copper chill of 25 mm thickness to study the effect of corrosion behavior....

Utilization of Co-Zeolite imidazolate frameworks (Co-ZIF) as catalyst for organic transformations

An excellent conversions of benzaldehyde was obtained under solvent and solvent free conditions by utilizing Co(im)20.5 DMA as catalyst for the synthesis of benzylidene malononitrile. The catalytic prospect of this crystalline porous framework was extended to oxidation reactions involving ethylene glycol (EG) and ethylbenzene (EB). Unexpectedly, EG was totally oxidized to oxalic acid; which demonstrates the catalyst...
