    CORROSION INHIBITION OF BENZOTHIAZOLE DERIVATIVES ON MILD STEEL IN ACIDIC MEDIUM
    (PSGR Krishnammal College for Women, 2012) Parameswari K; Chitra S; Selvaraj A; Brindha S; Menaga M
    The influence of two Benzothiazole derivatives, namely Benzothiazole-2-yl-semicarbazide (SCBT) and N-Benzothiazole-2-yl-N’-Phenylhydrazine (PHBT) on the corrosion inhibition of mild steel in 1M H2SO4 was studied by weight loss and electrochemical (Polarization and AC-Impedance) techniques. The synergistic effect by the addition of halide ions had been studied. The results showed that inhibitor performance depends on concentration of inhibitors, temperature and molecular structure. Polarization studies revealed that these compounds behave as cathodic inhibitors. This was supported by the impedance measurements. The inhibition action of benzothiazole derivatives occurs via adsorption of the compounds on mild steel surface. The adsorption was spontaneous and followed Langmuir adsorption isotherm. Thermodynamic parameters were calculated for the adsorption process. The results indicate that both PHBT and SCBT are excellent corrosion inhibitors

    INVESTIGATION OF BENZOTHIAZOLE DERIVATIVES AS CORROSION INHIBITORS FOR MILD STEEL
    (Portuguese Electrochemical Society, 2012) Parameswari K; Chitra S; Selvaraj A; Brindha S; Menaga M
    Abstract: studied by weight loss, potentiodynamic polarization andAC-impedance techniques. The synergistic effect by the addition of halide ions had been studied. The experimental results showed that the inhibition efficiency increases with increasing inhibitor concentration, but decreases with increasing temperature; potentiodynamic polarization curves showed that benzothiazole derivatives acted as cathodic inhibitors in 1 M H2SO4. This was supported by the impedance measurements which showed a change in the charge transfer resistance and double layer capacitance, indicating adsorption of Benzothiazole derivatives on the mild steel surface. Atomic absorption spectroscopy studies showed that the inhibition efficiency increases with increasing inhibitor concentration.

    A STUDY ON THE PERCEPTION OF GENERATION Z-THE FUTURE OF DIGITAL ERA
    (GRD Institute of Management, 2020-01) Brindha S; SaranyaPriyadarshihni C
    Generation Z, also known as the igeneration, was born after 1995, which means the eldest among them will start graduating from college and may already be part of the workforce or internship programs. It's easy to assume Gen Z workers will be just an extension of the Millennial, but studies show that's not really the case. The Z Generation is predicted to bring about a drastic change in the upcoming workforce. By the end of this decade, the workplaces are slated to imbibe various differences to harness the distinct advantages this generation will bring to the productivity levels and faces of organizations worldwide. The article explores the factors that GenZ considers as important in their work place
