In this research, the feasibility of using mathematical modelling in the ball milling process has been evaluated to verify the hardness changes of an aluminium nanostructure. Considering the model of normal force displacement (NFD), the radius of elastic-plastic and normal displacement of two balls were computed by applying analytical modelling and coding in MATLAB. Properties of balls and alum...

Nanoparticles are atomic or molecular particles with at least 1–100 nanometer diameters. They have entered vastly into the world of agriculture and biology; this is because of their special effect and their unique features. Their unknown impact on living things and the ecosystems has caused a lot of concern. This research was done in order to study the effects of nano-TiO2 and nano aluminium on...

Background:In recent years, the use of chemicals in agriculture, industry, and public health has become so common that the environment is continuously contaminated by the toxic substance-like metals. Aluminum released due to anthropogenic activities such as mining and industrial uses. Aluminium has several industrial uses. The present study was designed to investigate the effect of aluminium ch...

Unmordanted haematein in aqueous solution varies in colour from yellowish orange at pH 3 to bluish magenta at pH 9. In the presence of aluminium sulphate, the colour of solutions of haematein at any particular pH depends on the number of aluminium atoms to each molecule of haematein. At pH 4-6 the colour varies from yellowish orange through dull red to rose as the number of aluminium atoms to e...

Treatment of hyperphosphataemia consists of dietary phosphorus restriction and/or dialysis and phosphate binders. Almost all dialysis patients require phosphate binders (calcium acetate, calcium carbonate, aluminium hydroxide). The use of calcium-based phosphate binders can result in chronic calcium overload, hypercalcemia and soft tissue calcification. Hypercalcemia is particularly common in p...

The staining reaction of chromatin by aluminium-hematoxylin was investigated. Intense staining, which proved dependent on nucleic acid content, was achieved by using either the preformed lake, mordanting followed by hematoxylin, hematoxylin alone or the lake at high ionic strength. Extraction procedures removed aluminium ions from chromatin but the lake was retained. Chromatin fluorescence indu...

This chapter constitutes an introduction to creep and to the creep response of Aluminium and its alloys. Its major goals are: to provide basic information on creep and its mechanisms to give a description of the more extensively used mathematical relations among creep variables (time, stress and temperature) to illustrate the creep response of pure Aluminium and of Al-Mg alloys to provide a syn...

The activity of aspartate aminotransferase (AST) in human serum has been widely determined as a diagnostic aid in liver disease. In this study, the effect of aluminium on AST isoenzymes in relation to aluminium intoxified patients has been investigated. Using gel filtration chromatography technique with Sephacryl S-300, mitochondrial aminotransferase (m-AST) and cytosolic aminotransferase (c-AS...

Dialysis is one of the effective methods which has been used since 1955 for the treatment of patients suffering from renal failure( more often of its chronic type). The dialysis results in the elimination of waste materials like urea and creatinine from the body, on the other hand, it can affect the serum contamination of the dialysis fluid. Aluminium is one of trace elements which its serum le...

In the last decade, superfine powders of metals synthesized by several methods have become widely used in a number of different fields of material science. Superfine aluminum powders (SFAPs) have a broad application in energetic formulations. Aluminum powders have a high combustion enthalpy, which is why they are widely used in propellants, explosives and pyrotechnics. The decrease in the size ...
