Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The inhibition efficiency of six inhibitors namely Cetyl trimethyl ammonium bromide, Sodium dodecyl sulphate, Tween 80, Tween 60, Tween 20 and Triton X 100 in controlling corrosion of carbon steel in well water has been evaluated by weight loss method. The formulation consisting of 200 ppm of surfactants and 50 ppm of Zn2+ gives 96%, 92%, 90%, 88%, 85%, 84% inhibition efficiencies respectively. A synergistic effect exists between surfactants and Zn2+. Polarization study reveals that surfactant-Zn2+ system functions as a mixed kind of inhibitor. Mechanistic aspects have been studied by Polarization and AC-impedance spectra. AC impedance spectra reveal that a protective film is formed on the metal surface. FTIR spectra reveal that the protective film consists of Fe2+-surfactant complex and Zn(OH)2. The formation of mono layer and hydrophobic nature were confirmed by AFM, FTIR and contact angle measurements. As the value of contact angle increases, hydrophobicity increases and hence corrosion resistance increases. The self assembling nanolayers of the surfactants offer better corrosion inhibition efficiencies. 68 pp. Englisch.

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Corrosion Inhibition efficiencies of amino acids such as L-Tyrosine,L-Cysteine, L-Lysine, L-Valine and L-Serine in well water have been calculated by weight loss method. The mechanistic aspects have been studied by Polarization study, AC impedance spectra FTIR, UV and Fluorescence Spectra, AFM, SEM and EDAX. By using Density Functional Theory (DFT) various quantum chemical parameters such as EHOMO, ELUMO, energy gap, electron affinity, Ionization potential, absolute electro negativity have been calculated. The theoretical results were found to be consistent with the experimental data generated. It is observed that L-Tyrosine (250 ppm) + Zn2+(50 ppm) system has good inhibition efficiency. The reason for the high Inhibition Efficiency of L-Tyrosine is due to the presence of aromatic ring (electrons) in the system. L-Tyrosine (250ppm) + Zn2+ (50ppm) system has high LPR value than other amino acid inhibitor systems. This system has higher has higher charge transfer resistance value and lower double layer capacitance value than other systems. The protective film has been analyzed by FTIR, UV and Fluorescence Spectra, AFM, SEM and EDAX. The protective film is in nanometer scale. 64 pp. Englisch.

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Die Hemmwirkung von sechs Inhibitoren, nämlich Cetyltrimethylammoniumbromid, Natriumdodecylsulfat, Tween 80, Tween 60, Tween 20 und Triton X 100, bei der Bekämpfung der Korrosion von Kohlenstoffstahl in Brunnenwasser wurde mit der Gewichtsverlustmethode bewertet. Die Formulierung, die aus 200 ppm Tensiden und 50 ppm Zn2+ besteht, ergibt 96 %, 92 %, 90 %, 88 %, 85 % bzw. 84 % Hemmungseffektivität. Es besteht ein synergistischer Effekt zwischen Tensiden und Zn2+. Die Polarisationsstudie zeigt, dass das Tensid-Zn2+-System als gemischter Inhibitor funktioniert. Mechanistische Aspekte wurden durch Polarisations- und AC-Impedanzspektren untersucht. AC-Impedanzspektren zeigen, dass sich ein Schutzfilm auf der Metalloberfläche bildet. Aus den FTIR-Spektren geht hervor, dass der Schutzfilm aus einem Fe2+-Tensidkomplex und Zn(OH)2 besteht. Die Bildung der Monoschicht und die hydrophobe Natur wurden durch AFM-, FTIR- und Kontaktwinkelmessungen bestätigt. Mit steigendem Kontaktwinkel nimmt die Hydrophobie und damit die Korrosionsbeständigkeit zu. Die selbstorganisierenden Nanoschichten der Tenside bieten eine bessere Korrosionsschutzwirkung. 64 pp. Deutsch.

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -L'efficacité d'inhibition de six inhibiteurs, à savoir le bromure de cétyle triméthyle ammonium, le sulfate de sodium dodécyle, le Tween 80, le Tween 60, le Tween 20 et le Triton X 100, dans le contrôle de la corrosion de l'acier au carbone dans l'eau de puits a été évaluée par la méthode de la perte de poids. La formulation composée de 200 ppm d'agents de surface et de 50 ppm de Zn2+ donne respectivement 96 %, 92 %, 90 %, 88 %, 85 % et 84 % d'efficacité d'inhibition. Il existe un effet synergique entre les agents de surface et le Zn2+. L'étude de polarisation révèle que le système tensioactif-Zn2+ fonctionne comme un type d'inhibiteur mixte. Les aspects mécanistiques ont été étudiés par des spectres de polarisation et d'impédance CA. Les spectres d'impédance CA révèlent qu'un film protecteur se forme sur la surface du métal. Les spectres FTIR révèlent que le film protecteur est constitué d'un complexe Fe2+-surfactant et de Zn(OH)2. La formation d'une monocouche et la nature hydrophobe ont été confirmées par des mesures AFM, FTIR et de l'angle de contact. Plus la valeur de l'angle de contact augmente, plus l'hydrophobie s'accroît et plus la résistance à la corrosion augmente. Les nanocouches auto-assemblées des agents de surface offrent une meilleure efficacité d'inhibition de la corrosion. 64 pp. Französisch.

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Corrosion is a naturally occurring phenomenon. To limit the corrosion behavior of rebar steel in concrete (simulated concrete pore solution -SCPS), the use of inhibitors is a significant method. In the present study the following oxyanions were studied as corrosion inhibitors: Potassium permanganate (PP), Sodium molybdate (SM), TriSodium phosphate (TSP), Sodium Potassium Tartrate (SPT), Potassium dichromate (PDC) and Tri Sodium Citrate (TSC). They act as good corrosion inhibitors The mechanistic aspects of corrosion inhibition are based on the results obtained from weight loss method, the polarization study, AC impedance spectra measurements, UV visible absorption spectroscopy, Fluorescence spectroscopy, surface examination techniques like FT-IR spectroscopy, Cyclic Voltammetry, Scanning electron spectroscopy (SEM) and Energy dispersive analysis of X rays (EDAX) and Atomic force microscopy (AFM).The results the weight loss study show that the formulation consisting of 250 ppm of Inhibitor and 50 ppm Zn2+ has greater percentage of corrosion inhibition efficiency (IE), in controlling corrosion of rebar steel immersed in SCPS prepared in well water. 136 pp. Englisch.

In Madurai, Meenakshi Amman Temple has high 'gopuram' towers ornamented with colourful figures. Recently there were many deaths due to dengue fever. Government of Tamil nadu is taking necessary steps to control dengue fever. One of the steps is telling about the importance of 'NILAVEMBU KASAYAM' (Extract of Nilavambu) in the treatment of dengue fever. One of the eminent actors in Tamil nadu Sri Kamal Haasan requested his followers to distribute this extract only after being convinced the medicinal values of this extract. This created more awareness and significance of Nilavembu and Dengue. This motivated the authors to write about the origin of dengue fever, the mosquito, symptoms, treatment, after effects, the significance of nilavembu, its active principles and its medicinal values. This resulted in the publication of this book. Papaya leaves juice is also recommended for the treatment of Dengue fever. World Health Organization has taken necessary steps to control Dengue fever. Development of Immunity is the best way to combat Dengue fever. Food items which develop immunity in body are presented. 240 pp. Englisch.

For example, it is safe, easy to handle, widely available, and inexpensive in most industrialized regions of the world. Water is a more efficient heat transfer medium than many other materials, especially compared to air. Water cooling is a method of heat removal from components and industrial equipment. As opposed to air cooling, water is used as the heat conductor. Water cooling is commonly used for cooling automobile internal combustion engines and large industrial facilities such as steam electric power plants, petroleum refineries, hydroelectric generators and chemical plants. Other uses include cooling of lubricant oil in pumps, cooling the barrels of machine guns; for cooling purposes in heat exchangers; and recently, cooling of various major components inside high-end personal computers. Recent trends in cooling water systems and modern approach in use of corrosion inhibitors for cooling water systems are presented. This book is useful to those working on corrosion inhibitors, mainly to those working on corrosion inhibitors for cooling water systems. 236 pp. Englisch.
