Modulating the Surface Electronic Structure of Pt With Co2P for Effective Methanol Oxidation Reaction and Hydrogen Evolution Reaction Under Acidic and Alkaline Conditions

Carbon Energy, EarlyView.
A pH‐universal Pt@Co2P/Co/CNF electrocatalyst, fabricated via in situ phosphorization and replacement, exhibits exceptional HER and MOR activity in both alkaline and acidic media due to synergistic Pt‐Co₂P interactions that prevent Pt desorption.

Corrosion Inhibition of a Cu-Ni Alloy in LiBr+Ethylene Glycol+H2O Mixtures with Nitrates, Chromates and Molybdates

International Journal of Electrochemical Science, 2014
A study of the corrosion inhibition of a 90(wt.%)Cu-10Ni alloy in a 55LiBr+ethylene glycol+H2O solution by using inhibitors such as lithium chromate, lithium molybdate and lithium nitrate in a concentration of 5 ppm, have been evaluated at different ...

Diffusion of Carbamazepine in Hydrophobic Zeolites: A Comparative Study Using Classical and Machine‐Learned Potentials

Chemistry – A European Journal, EarlyView.
Can hydrophobic, shape‐selective zeolites efficiently remove the persistent pharmaceutical CBZ from water? This work moves beyond the static picture of interaction energies by modeling diffusion with umbrella sampling and machine‐learned potentials. Even high intrinsic diffusion barriers can be overcome through exergonic adsorption from water, yielding

Durene conversion in a methanol‐to‐jet process: Exploring conversion at 150–350°C over different acid catalysts

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Acid catalyzed conversion of durene by isomerization, disproportionation, and transalkylation is of interest to the development of a methanol‐to‐jet process to reduce the amount of durene in the kerosene. It was of interest to determine whether durene conversion could be performed at a temperature lower than 350°C.

Microstructural Changes during High Temperature Service of a Cobalt-Based Superalloy First Stage Nozzle

Advances in Materials Science and Engineering, 2016
Superalloys are a group of alloys based on nickel, iron, or cobalt, which are used to operate at high temperatures (T > 540°C) and in situations involving very high stresses like in gas turbines, particularly in the manufacture of blades, nozzles ...
