Abstract Oxalate concentration differs in various daily consumed food products. The role of oxalic acid in the human body is very significant, as its compounds are responsible for the stability of biological membranes. However, insoluble calcium and magnesium oxalates can be accumulated in the body in the form of kidney stones. Oxalate concentration has been measured by high performance liquid, gas after derivatization and ion chromatography (IC). The most effective method for the simultaneous determination of oxalate and inorganic anions is ion chromatography with conductometric detection. Here, we report the results of the measurement of oxalic acid in bleak and green tea samples. Separation was performed by IC on an anion-exchange column Shodex IC SI-90 with surface-layer sorbent and conductimetric detection. The main analytical features of the method were: limit of detection of oxalic acid 0.03 mg/l, linear range 0.1-20 mg/l, correlation 0.9998, relative standard deviation 1%. The method did not need specific sample treatment and was successfully applied to the analysis of black and green tea samples. Oxalic acid was determined in the ranges 16.7-84 mg/l for green tea and 63-116 mg/l for black tea. Green tea contained lower oxalate ions concentration than black tea. The IC method has a lower detection limit for oxalate ions than HPLS and GC, ten and two times less, respectively

Spreading Processes

The results of experimental studies of kinetics of spreading processes of epoxy binders on the surface of a carbon (cloth) tape depending on a reinforcement pattern are presented. A copper coating of 100 nm thickness was deposited on reinforced materials by magnetron sputtering. It has been found out that a metal coating on the surface of a carbon tape and cloth leads to a considerable increase in the rate of spreading processes only for the laying-out pattern 0°, when binder movement in capillaries is provided. The deposition of a copper coating on the surface of the carbon tape and cloth has considerably the bigger influence on kinetics of the spreading processes, increasing it by 35%.

Insight Into

Modeling the semisolid structure formation is of significance in both understanding the mechanisms of the formation of such structure and optimization of the solidification conditions for the required structure. A modified cellular automaton (mCA) model has been developed, which is coupled with macroscopic models for heat transfer calculation and microscopic models for nucleation and grain growth. The mCA model is applied to Al - Si alloys, one of the most widely used semisolid alloys. It predicts microstructure morphology and grain size during semi-solid solidification, and determines the effects of poring temperature and mould temperature on the final microstructure. The simulated results are compared with those obtained experimentally. The resulting simulations give some insight into the mechanisms about the semisolid structure formation in Controlled Nucleation process.

The Relationship

This paper reviews briefly the relationship between the growth mechanism and matter transport using as an example the best currently applied metallic materials being alumina formers. The attention is paid to the experimental approach as well as to the interpretation procedure of experimental results. The scale structure, microstructure, morphology and phase composition are indicated as factors strongly affecting its growth mechanism. The attempt is made to elucidate the possible relationships between the obtained experimental results and actual scale growth mechanisms operating during oxidation exposures.

The method ofinduction cladding was adopted to make nickel-base layer on the surface ofsteel components in this test, and microstructure morphology, rigiditydistribution of the alloy layer made by cladding were analyzed and studied. Theresults shows that there is obvious bright white transition zone between thecladding alloy layer and the body, which forms an excellent metallurgicalbonding, microstructure of the alloy cladding layer is eutectic structure ofaustenite + carbide (austenite dendrite can be seen at individual parts), axialand radial rigidity are evenly distributed; bonding strength of cladding alloylayer is high without air hole and slag inclusion, with high flatness ofcylindrical surface, small machining allowance and low cost, etc.
