[en] The study of the electrochemical behavior of wrought and welded Alloy 22 was carried out in 5 M CaC12 at various temperatures. Comparisons were made between the electrochemical behaviors of the wrought and welded forms of Alloy 22 Multiple Crevice Assembly (MCA) specimens. The susceptibility to corrosion was found to increase with increase in temperature in both the wrought and the welded forms of the alloy. Nevertheless, degree of susceptibility was found to be similar in both the wrought and welded

[en] In order to study the effectiveness of Calcium chloride treatments on post harvest quality and storage behavior of 'Surkh' cultivar of loquat, fruit was dipped in three concentrations (1%, 2% and 3%) of Calcium chloride for two minutes and stored in soft board cartons at 4 deg. C in a cold store for 10 weeks period. The fruit was harvested at mature ripe stage, clipped, sorted and washed before applying the treatments. Changes in weight loss, firmness, total soluble solids (TSS), browning index (BI), ascorbic acid, titratable acidity (TA) and relative electrical conductivity (REC) were studied. One percent CaCl/sub 2/ did not affect quality parameters of the fruit compared to control treatment, whereas, 2% and 3% CaCl/sub 2/ retained maximum firmness, TSS, ascorbic acid content reduced browning index (BI), relative electrical conductivity (REC) and weight loss up to 4-5 weeks.

[en] The sewage of household chemicals enterprises with high content of surface-active substances and organic dyes on their purification by bentonite clays is studied. It is defined that the purification effect increases at combined treatment by clayey material and electrolyte - calcium chloride. Studied samples have a high adsorptive ability. The extraction rate reaches 96-98%. Conducted researches gives the possibility to use the bentonite clays as sorbent for purification of sewage from surface-active substances and dyes.

[en] The study of the electrochemical behavior of wrought and welded Alloy 22 was carried out in 5 M CaCl₂ between 45 and 120 C. Comparisons were made between the electrochemical behaviors of the wrought and welded forms of Alloy 22 Multiple Crevice Assembly (MCA) specimens. The susceptibility to corrosion was found to increase with increase in temperature in both the wrought and the welded forms of the alloy. The weld metal was found to be less susceptible to localized corrosion under the conditions tested

[en] Currently problems of large toxicity, poor biocompatibility and high cost between polymer and crosslinking agent are found in traditional ionic gel electric actuator. To conquer such challenges, in this work, sodium alginate(SA) and calcium chloride(CaCl₂) were used to produce the biological gel electric actuator (BGEA). Furthermore, to achieve better response performance of the BGEA, two kinds of BGEAs with different concentrations of CaCl₂ and different concentrations of glycerol were prepared experimentally, and then the response performance of the BGEA was studied. The effect of calcium chloride on the BGEA showed that the concentration of calcium chloride had a great influence on the response performance of the BGEA, and the best concentration of calcium chloride was 0.95 g L⁻¹. Compared with the BGEA without crosslinking, the response speed and deflection displacement were increased by 1.64 times and 1.52 times respectively. The effect of glycerol on BGEA showed that although the response speed of the BGEA without glycerol was faster, the BGEA itself was dry, easy to break and weak to the external shock. Therefore, adding 1 ml of glycerol into the electrolyte membrane of the BGEA, not only increases the deflection displacement of the BGEA, but also avoids large reduction in its response speed. (paper)
