Design And Fabrication Of Aluminum Based Ws2 Nano-Composite Through Powder Metallurgy, Umida Ziyamuhamedov, M Wani
Design And Fabrication Of Aluminum Based Ws2 Nano-Composite Through Powder Metallurgy, Umida Ziyamuhamedov, M Wani
Technical science and innovation
In this research paper, experimental studies on the fabrication of Aluminum based metal matrix composites composed are presented. The Aluminum based metal matrix composite was developed with varying percentage of WS2. Physical and mechanical properties were measured to assess the influence of addition of WS2 on density and micro hardness of composite.

Technical science and innovation
The technology has been developed for the production of unsaturated alloy nickel hydrogenation catalysts. The results of the study of the phase, chemical compositions and structure of nickel alloys and catalysts showed that the ferroalloy introduction as a modifying additive affects the NiAl3 / Ni2Al3 ratio. The studied alloying metals are practically insoluble in alkali and exist in the catalyst in dissolved states. All these changes favorably affect the catalytic properties of modified nickel catalysts in the benzene hydrogenation reaction. A systematic study of the stationary catalyst activity with addition of ferroalloys in the continuous catalytic …

Alum And Pacl Coagulation, Winarni Winarni
Makara Journal of Technology
Alum and PACl Coagulation. Coagulation occurs by interaction of aluminum hydrolysis products with the contaminant such as colloidal particles. It is necessary to consider the different aluminum species that may present during specific conditions, since the mechanism of turbidity removal is dependent upon them. PACl consists of preformed aluminum hydrolysis products, which are stable below pH 6 and less sensitive than in situ hydrolysis product, alum. The benefits of PACl relative to alum have been investigated as a function of pH and Al dosages. Specific conditions and aluminum species that exist during the certain mechanisms of coagulation are discussed. Results …
