It has recently been reported that aluminum plays a very important role in reducing the activity of Krebs-cycle enzymes and glutamate dehydrogenase in rat brain homogenate. Therefore, it is necessary to identify the aluminum binding ability with the pivotal substrate alpha-ketoglutarate in biological systems. The interactions of aluminum with alpha-ketoglutarate were studied with pH-potentiomet...

abstractin this paper, we investigate effect of fe–intermetallic compounds on plastic deformation of closed-cell composite aluminum foam as filler of thin-walled tubes. however, deformation of the aluminum foam-filled thin-walled tubes as crushed-box will be presented in part (ii). composite foams of alsi7sic3 and alsi7sic3-(fe) as closed cell were synthesized by powder metallurgy foaming metho...

Corrosion tests of 316L and two intermetallic compounds Fe3AI and FeCrSi in industrial Galvanizing (Zn-0.18Al), GALFAN (Zn-5AI), GALVALUME (Zn-55AI), and Aluminizing (AI-8Si) baths and lab-scale static baths were conducted. In on-line tests in industrial hot-dip baths, 316L steel shows better corrosion resistance than Fe3AI in Galvanizing, GALFAN, and GALVALUME baths. The corrosion resistance o...

It has been postulated that organic-rich planetesimals played a crucial role in the origin of life, but the mechanism by which the organics could have been delivered to a planetary surface is not well understood. We have developed a technique for launching aluminum projectiles at velocities above 11.0 km/s [1]. We fabricated a target that represented both the planet and the bolide. An inorganic...

The main drawback of friction stir welding (FSW) dissimilar metals is the formation intermetallic compounds (IMCs), which are brittle and affect strength joint. these inevitable due to their low enthalpy formation; however, emergence an indication metallurgical bonding between metals. This means that determining factors intermetallics should be optimal ensure joint and, at same time, performanc...

One of the ways to prevent generative diseases is by using natural antioxidant compounds. The flavonoid compounds in flower parts M. gigantea have a role antioxidants. Thus study aimed test activity and levels flowers. was carried out UV-vis spectrophotometry 2,2-diphenyl-1-picrylhydrazyl assay 10% aluminum chloride potassium acetate, both tests quercetin as comparison. results this obtained IC...
