We study the drying and film formation of a model ternary system comprising an inorganic salt (aluminium chlorohydrate, ACH), a humectant (glycerol) and water. Employing viscometric, X-ray diffraction, calorimetric, dynamic vapour sorption, spectroscopic, gravimetric and adhesion measurements, w...

Use of underarm aluminium (Al)-based antiperspirant salts may be a contributory factor in breast cancer development. At the 10th Keele meeting, Al was reported to cause anchorage-independent growth and double strand DNA breaks in MCF10A immortalised non-transformed human breast epithelial cells....

Calcium aluminate cement (CAC) was ground for 1 and 2 h to investigate the impact of mechanical grinding on CAC hydration at 30 °C and CAC-bonded castable strength. Phase composition and microstructure of unground and ground cements after hydration for predetermined times and terminated by the ...

The production of high alumina refractory cements (>75% Al2O3) is traditionally carried out in furnaces heated with both electric power (submerged arc furnaces) and fossil fuels (coke, natural gas). This heating system has several disadvantages: electricity price, contamination of the cement or ...

Deeply dehydrated calcium aluminate glasses doped by rare-earth ions were synthesized and investigated. Spectroscopic properties of Tm3+ and Ho3+ doped glasses were found attractive for fiber lasers emitting in 2–2.5 μm spectral range. Cascade laser action (at 2300 and 2100 nm) in Tm doped bul...

The selection of compounds used as inter-well tracers has traditionally been done taking into consideration the goal of the test and the ease in analyzing the chemicals used. This often led to improper selection of the tracers and insufficient knowledge about their behavior under typical reservo...

The Fourier transform Raman and Fourier transform infrared spectra of 3,4-dichlorobenzyl alcohol were recorded in the solid phase. The equilibrium geometry, harmonic vibrational frequencies, infrared intensities and Raman scattering activities, depolarization ratios, reduced masses were calculat...

Single crystal platelets of AlB2 have been prepared by (1) an extremely rapid aluminothermic reaction between B2O3 and excess Al at temperatures reaching more than 1500 °C and (2) a slow reaction between elemental B and excess Al at 975 °C. The crystals prepared by the second method are typica...

Some peculiarities in the behaviour of hydrogen, nitrogen and oxygen impurities in ceramic samples of boron carbide and aluminium dodecaboride with semiconductor features have been studied. The relationship between the gas content in the items produced by hot compaction and sintering, and their ...

Some thermomechanical properties of boron carbide and aluminum dodecaboride are presented. The dependence of the bending strength on the temperature of B4C and AlB12 in the ductile rupture region was studied. It was detected that the ductile rupture of B4C starts at temperatures above 1500°C wh...

The correlations between structures and mechanical characteristics of α-AlB12-, AlB12C2-, B4C-based lightweight ceramics and composites synthesized or sintered by hot pressing (at 30 MPa) and SiC-based ceramics obtained by reactive sintering are compared. The effect of C, TiC and SiC additions ...

In this work, the aluminum conductors containing different trace elements have been prepared. And the influence of the trace elements on the microstructures and properties of aluminum conductor has been examined. It is found that the higher content of Fe and Si as well as higher Fe/Si ratio is h...

Plasma paste boriding at temperature of 800 °C (1073 K) for 3 h was applied in order to produce hard ceramic phases on the surface of Ni-based alloys with various chromium concentrations. The microstructure of boride layer depended on the chemical composition of substrate material. The increase...

In the aluminium processing industry, the tribo-corrosion of a metal by molten aluminium or its alloys is an urgent problem, as the removal of the corrosion products leads to material losses and even failure. Therefore, a novel Fe-15.3 wt % Cr-3.1 wt % B-6.2 wt % Mo alloy was designed, and its i...

A generalized bond-strength model of hardness was applied to of Re3B, Re7B3, ReB2, Ru7B3, RuB, Ru2B3, RuB2, OsB, Os2B3, OsB2, and metal substituted aluminum diborides of MgB2 type M0.5Al0.5B2 (M = Li, Na, Mg, K, Ca, Sc, Ti, V, Y, Zr, Nb, Mo, Tc, Ru, Hf, Ta, W, Re, and Os). The resulting hardness...

Low-temperature synthesis of aluminium boride (AlB12) powders by mechanochemical synthesis of Al and B powder blend has been carried out. The influence of milling time on the phase formation temperature and annealing time of AlB12 was investigated. X-ray diffraction of the milled and annealed po...

Many textiles have been often used in marine environments for a wide variety of purposes. Consequently, effective and clean methods to prevent biofouling in these textiles are needed. In this study, a nylon mesh doped with AgI was examined for its antifouling performance. The nylon mesh was iodi...

Iodide in natural waters is an important nutrient to aquatic organisms and its determination is of relevance to marine aquaculture. For this reason it is of interest to have a simple analytical method for determination of iodide in water samples. Iodide in seawater can be determined electrochemi...
