Tetrahydro-dibenzo[a,d][7]annulene-5,11-dihydrazone and Magnesium oxide Used to Control the Corrosion of Aluminium in Chloride ions Environment
Abstract: Chloride ions interact with aluminium in marine atmosphere to form corrosion cell. Due to this corrosion reaction occurs on their surface, aluminium is oxidized into Al3+. The corrosion reaction accelerates deterioration in metal and it produces galvanic, pitting, stress, crevice, intergranular corrosion. Chloride ions decrease internal and external strength of aluminium metal. It is a very important metal so used in different appliances for e.g. road, water, air transports, housing, …

Utilization of Advance Geopolymer in Concrete: A Review
Abstract: Climate change has several adverse impacts like changes in weather, untimely rains, depleting water, droughts, flash floods, acute and early summer and chilling winter. Equally, another bigger challenge to the society is foul smell whether it is river, pond, drain, public toilets or garbage dump yards. It is due to emission of hydrogen sulphide, methane and other toxic gases. Methane in pure form does not create any foul smell, however …
