For the first time, the hydrogen evolution reaction (HER) electrocatalytic performances of incompressible γ-Mo0.5W0.5C, prepared by high-pressure, high-temperature (HPHT) synthesis, were investigated in the electrolyte. The polarization curve of the γ-Mo0.5W0.5C cathode exhibits the current density of 50 mA·cm−2 at an overpotential value of 320 mV. The corresponding Tafel slope of the incompres...

Water-based fracturing fluids are among the most common fluid types used in hydraulic operations. However, these tend to cause damage water-sensitive formations. Foam comprises a small amount of base fluid, and compressible gas such as carbon dioxide nitrogen has emerged more ecologically friendly option fracture is an attractive since it low density high viscosity. The applicability foamed fra...

Aimed at improving the accuracy of dose determination in radiation medicine, this thesis explores the radiation detection properties of synthetic diamond crystals of various types and investigates the possibility of developing a single probe with synthetic diamond as sensor for the dosimetry of various beam types under large as well as small-field conditions. The study was conducted on two HPHT...

Abstract Rheological and filtration properties of drilling fluid contribute a vital role in successful operations. parameters such as apparent viscosity (AV), plastic (PV), yield point (YP) gel strength fluids are very essential for hydraulic calculations lifting drill cuttings during the operation. Control loss volume is also important cost effective Therefore, main goal this research to impro...
