Mitochondria play an important role in cellular energetics and balance. High levels of reactive oxygen species induce oxidative stress in living cells. Arsenic is known to induce reactive oxygen species (ROS), and oxidative stress is the major cause of mitochondrial impairment leading to cell death. It also explains the preneoplastic events and can...

The potential role of oxidative stress in the pathogenesis induced by arsenic propose that antioxidants can be deliberated as an alternative approach in alleviating arsenic-induced toxicity. The aim of this work was to assay in vitro the potential advantageous effects of plant flavonoid rutin against arsenate exposure, by studying lipid peroxidatio...

Tetranitro cobalt phthalocyanine (TNCoPc) was used as a corrosion inhibition of mild steel in a 0.25 M hydrochloric acid medium using Tafel polarization and electrochemical impedance spectroscopy in a temperature range of 303 to 323 K. The concentration of inhibitor used was in the range of 1.25–5 mM. The surface morphology was studied using scanni...

The corrosion behavior of aluminum in the hydrochloric acid medium of pH 3 was studied using Tafel polarization and electrochemical impedance spectroscopy techniques in the presence or the absence of the Murraya koenigii (commonly known as curry) leaves extract at 303 K to 323 K. The concentration of the inhibitor used was in a range of 0.05–0.4 gL...

The inhibitive effect of Andrographis panniculata plants extract (APPE) on the corrosion control of aluminum was investigated in hydrochloric acid medium of pH=3 using Tafel polarization and electrochemical impedance spectroscopy (EIS) techniques in the temperature range of 303 to 323K. The concentration of inhibitor used was in the range of 0.05−0...

Aqueous extract of stems of Tinosporacordiofolia was studied as a corrosion inhibitor for aluminum in sulfuric acid (pH = 3) by using potentiodynamic polarization method and electrochemical impedance spectroscopy (EIS) technique in the temperature range of 30 °C to 50 °C. The concentrations of inhibitor used were in the range of 50- 400ppm. Inhibit...

The inhibitive effect of Curry leaves extract (CLE) on the corrosion behavior of aluminum in sulfuric acid (pH = 3) was investigated by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques in the temperature range of 30 ° C to 50 ° C. The study was done by varying the concentrations of inhibitor from 0.05 g L−1 t...

The corrosion behavior of commercial sample of aluminium was investigated in hydrochloric acid medium of concentrations 0.001M–1.0 M in the temperature range of 30°C–50°C, by electrochemical techniques. The surface morphology of the corroded sample was studied using scanning electron microscopy (SEM). The corrosion rate increased with the increase...

The inhibitive effect of Carica papaya seed extract (CPSE) on the corrosion behavior of aluminium in H2SO4 at pH 2.6 was investigated by using Tafel polarization and electrochemical impedance spectroscopy (EIS) techniques in the temperature range 30°C to 50°C. The concentration of inhibitors used was in the range of 50-400ppm. The surface morpholog...

The inhibitive effect Carica papaya seed extract (CPSE) on the corrosion behavior of aluminium in sulphuric acid medium of pH 2.3 was investigated by using Tafel polarization and electrochemical impedance spectroscopy (EIS) techniques in the temperature range 30 to 50°C. The concentration of inhibitors used was in the range of 100-400ppm. The surfa...
