Enhanced copper surface protection in aqueous solutions containing short-chain alkanoic acid potassium salts.
The ability of dissolved potassium monocarboxylate salts to produce surface passivation and to inhibit aqueous corrosion of copper was studied. The electrochemical measurements indicate that the inhibiting efficiency of these compounds, with a general formula Cn-1H2n-1COOK or CnK (n=3...12), is dependent on the hydrocarbon chain length. The inhibiting efficiency was higher for a longer hydrocar...
متن کاملRubber Friction in Aqueous Solutions Containing Ions
Lubricants ordinarily operate by keeping two sliding surfaces separated. The efficiency of a lubricant may be expressed by equations of hydrodynamics where the mechanical properties of the films of lubricants are adequately defined by the properties of bulk lubricant. In the case of water lubrication of black rubber at slow speeds and low pressures the lubricating ability of water is shown to b...
متن کاملAqueous‐Containing Precursor Solutions for Efficient Perovskite Solar Cells
Perovskite semiconductors have emerged as competitive candidates for photovoltaic applications due to their exceptional optoelectronic properties. However, the impact of moisture instability on perovskite films is still a key challenge for perovskite devices. While substantial effort is focused on preventing moisture interaction during the fabrication process, it is demonstrated that low moistu...
متن کاملRibonucleic acid-deoxyribonucleic acid hybridization in aqueous solutions and in solutions containing formamide.
Hybridization in 6xSSC (SSC, 0.15m-sodium chloride-0.015m-sodium citrate) at 66 degrees C was compared with hybridization in formamide-6xSSC (1:1, v/v) at 35 degrees C. As expected, the RNA hybridization potential was labile in the former system and stable in the latter. DNA retention by filters was poor in the formamide system, but could be improved. Several other properties of the hybridizati...
متن کاملThe Color Removal of Dye-Containing Wastewater by Cerium (IV) Sulfate from Aqueous Solutions
In this study a giant reagent such as Ce (SO4 )2 was used for removing different initial dye concentration (10-1000 mg/l) of reactive red 31 (R.R31) less than two minutes in a laboratory scale whereas the percent of dye removal efficiency was %99.9. The Langmuir, Freundlich and Tempkin adsorption models were applied to describe the equilibrium isotherms. The Langmuir model agreed very well with...
