The corrosion behaviour of aluminium and6063 aluminium alloy was investigated in phosphoric acid of different concentrations at different temperatures. The study was done by electrochemical method, using Tafel polarization and electrochemical impedance spectroscopy (EIS) techniques. The kinetic parameters and thermodynamic parameters were calculated using Arrhenius theory and transition state t...
In this communication, we, for the first time, prepared phosphorus-doped cobalt disulfide nanosheets as highly advanced electrocatalysts for the hydrogen evolution reaction. It was demonstrated that P doping could significantly enhance the electrocatalytic performance of CoS2 nanosheets in terms of onset overpotential, Tafel slope, exchange current density, and stability.

Clustering is an important data exploration task. A prominent clustering algorithm is agglomerative hierarchical clustering. Roughly, in each iteration, it merges the closest pair of clusters. It was rst proposed way back in 1951, and since then there have been numerous mod-iications. Some of its good features are: a natural, simple, and non-parametric grouping of similar objects which is capab...
A facile, one-pot solvothermal method is developed to synthesize MoS2 nanoflowers (MoS2NFs) coated on reduced graphene oxide (rGO) paper. The resulting MoS2NF/rGO paper serves as a freestanding, flexible and durable working electrode for hydrogen evolution reaction (HER), exhibiting an overpotential lowered to -0.19 V with a Tafel slope of ∼95 mV per decade.
nanosized tio2 particles were prepared by sol–gel method. the tio2 particles were co-deposited with chromium using electrodeposition technique. in investigating of coating surfaces by scanning electron microscope (sem), the results showed that the morphology of the coating surface was changed by adding tio2 nanoparticles to the chromium coating. the corrosion behavior of the coatings was assess...
