acid extract of solanum tuberosum was tested as corrosion inhibitor for mild steel in 1 m hcl and h2so4 media using different techniques: weight loss (in different temperatures viz., 303, 313 and 323 k), potentiodynamic polarization, electrochemical impedance spectroscopy (eis) and sem techniques. the studies reveal that the plant extract act as good inhibitors in both the acid media and better...

This article presents the suitable chemical method for preparation of graphene oxide nanosheets. In order to examine the effects of HNO3/H2SO4 ratio on interlayer spacing and its comparison, the oxidation of graphite with HNO3 and H2SO4 in 1:2 and 1:3 volume ratios was done. Based on the reaction time and interlayer spacing, it was found that the optimum results were obtained when reaction was ...

A poly(aniline-co-m-ferrocenylaniline) was successfully synthesized on a glassy carbon electrode (GCE) by electrochemical copolymerization using a scan potential range from -0.3 to +0.9 V (vs. Ag/AgCl) in 0.5 M H2SO4 containing 30% acetonitrile (ACN), 0.1 M aniline (Ani) and 0.005 M m-ferrocenyaniline (m-FcAni). The field emission scanning electron microscope (FESEM) and electrochemical methods...

The optimization of carbon-based supercapacitors is of great technological importance for electrical energy storage. This challenge stresses the relevance of current attempts to increase the surface-related capacitance C/S (F m) of carbons. We show that for microporous carbons this property is practically constant for pore widths between 0.7 and 1.8 nm. The study is based on two independent app...

Local and global sensitivity and uncertainty methods are applied to a box model of the dimethylsulfide (DMS) oxidation cycle in the remote marine boundary layer in order to determine the key physical and chemical parameters and sources of uncertainty. The model considers 58 uncertain parameters, and simulates the diurnal gas-phase cycles of DMS, SO2, methanesulfonic acid (MSA), and H2SO4 for cl...
