Influence of Microstructure of 1050 Alloys on Electrograining in Nitric Acid

Electrograining of structurally characterised 1050 aluminium alloys in nitric acid has been examined by scanning electron microscopy. With control of alloy microstructure, particularly the size and distribution of second phase material, acceptable electrograined structures are generated with reduced power consumption. This is related directly to second phase particles providing sites in their zone of influence where pits initiate and subsequently propagate to develop the required uniformly convoluted surface.     

Effect of nano-sized metal compounds on the flame-proof properties of plasticized polyvinyl chloride

Based on data from thermogravimetric analysis and the oxygen index, a PVC composite containing nanosized particles of zinc oxide and amino-tris-methylenephosphonic acid has the best fireproofing indexes. The OI of this composite was 27.5%.     

Kinetics of phase transformations in a binary alloy surface layer at the selective dissolution. I. Theoretical analysis

A procedure of estimating the formation rate of the individual phase of an electrochemically positive component B⁰ at the anodic selective dissolution or corrosion of an A-B alloy in a potential range above the critical potential of the development of a morphologically unstable surface is proposed and theoretically founded.     

Significance of adrenal hormones in brain energy metabolism

Intensity of glycolysis was studied under conditions of immobilization stress and adrenalectomy as well as with administration of adrenaline and hydrocortisone. The processes of aerobic glycolysis, activity of enzymes of the tricarboxylic acid cycle and mitochondria respiratory chain, content of total, free and protein-bound glycogen, glucose-I-phosphate, glucose-6-phosphate, pyruvate, alpha-ketoglutarate, cytrate and macroergs in the brain are shown to depend on the level of adrenal hormones producing a multilateral effect on a series of energy metabolism links.
