The objective of the present research on fruit batteries was to compare the voltage produced by different fruits with different electrode combinations, keeping the cathode material unchanged (copper). The electrode pairs selected for the purpose are copper-iron (Cu-Fe), copper-zinc (Cu-Zn) and copper-aluminium (Cu-Al). The fruit acted as an electrolytic medium providing continuity to complete the electrical circuit. The potential differences created by each electrode pair were measured using a multimeter. From the results obtained, it was evident that the different fruits produced different voltages. The nature of the fruit is an indisputable criterion which decides the fruit battery voltage .The most important and relevant observation was that there was an increase in the voltage with increase in reactivity (oxidizing tendency) of the anode material. This observation was found to be true for all fruit batteries which were subjected to investigation and the result obtained could easily be explained based upon the positions of electrode materials in the activity series or electrochemical series.

SUMMARYThe ability of six different types of contamination control mats currently in use at the entrances to theatre suites and other clean areas to remove bacteria-carrying particles from theatre trolley wheels was compared. Marked differences in the effectiveness of this property were obtained; and all mats showed some disadvantages. Modification of one of the mats has resulted in improved efficiency under working conditions.

AbstractWe design a way that the anode hosts provide lithium ion in lithium ion battery operation. If the limiting factors of the cathode materials are less, there will be more alternatives for it. It was proven to be successful by two kinds of test cells based on LixCn as anode material, and β-FeOOH or Cr8O21 as cathode materials. Their theoretical capacities are much higher than those present electrode materials. Unlike the lithium secondary batteries with lithium metal foil or lithium alloy as anode, this type of lithium ion batteries with LixCn as anode prohibit dendrite formation during charging-discharge process. The idea of lithium ion sources coming from the anode can come true successfully as a result that steady protecting solution be sought for LixCn.

In this study, the effects of blending the un-branched acrylate polymer known as Poly (n-decyl acrylate), and the branched acrylate polymer known as Poly (iso-octyl acrylate), on the viscosity index (VI), and the pour point of the Iraqi base stocks 40, and 60 respectively, were investigated. Toluene was used as a carrier solvent for both polymer types. The improvement level of oils (VI, & pour point) gained by blending the oil with the acrylate derived polymers was compared with the values of (VI, and pour point) gained by blending the oil with a commercial viscosity index, and pour point improver. The commercial lubricant additive was purchased and used by Al-Daura Refineries. It consisted of an un-known olefin copolymer dissolved in an un-known carrier solvent. All polyacrylate derivatives and the commercial lubricant additive named HITEC5748 were blended with each type of oil in weight percentage of (2, 4, 6, 8, & 10) wt. %. The result of the study was that the improvement in the viscosity index and the pour point of both base stock types was higher when using the polyacrylate derivatives than when using the commercial olefin copolymer additive.
