The triprotic ammonium carboxylate ionic liquid crystal (2-hydroxyethyl)ammonium oleate (MO) has been studied as a neat lubricant and additive in two base oils, PAO6 100N. lubricants have used commercially pure copper-OFHC copper balls on disk reciprocating sliding contact at room temperature. Neat MO presents very good lubricating performance, with friction coefficient of 0.06 wear rate OFHC 4...

A Mo-modified H-MFI zeolite (Mo/H-MFI) catalyst is one of a typical catalyst for direct GTL (Gas to liquid), because it shows high activity for dehydroaromatization of methane in absence of oxygen. In this reaction, reduction of Mo species is brought about in contact with methane in initial step, and reduced Mo ions react methane to form carbide and/or oxycarbide species in next step. It has be...

Abstract In this study, a robust macroscale liquid superlubricity with coefficient of friction 0.004 was achieved by introducing molybdenum carbide (Mo 2 CT x ) MXene nanoparticles as lubricating additives in lithium hexafluorophosphate-based ionic at Si 3 N 4 —sapphire interfaces. The maximal contact pressure the state could reach 1.42 GPa, which far exceeds limit regime previous studies. resu...

Abstract The friction and wear reducing properties of ammonium thiomolybdate as a water‐soluble lubricant additive were evaluated using pin‐on‐disck tribometer on steel‐steel contact. tribological performance aqueous solutions prepared at concentrations between 0.1 0.3 wt% Mo the same load (10 N), entrainment speed, sliding distance temperature. Although there is reduction compared with pure wa...

 ABSTRACTBackground: An electron beam generated X-ray spectrum consists of characteristic X-ray and continuous bermsstrahlung. The aim of this research is calculating and comparing X-ray spectra for different target filter of mammograms. Materials and Methods: Monte Carlo is a very powerful tool to simulate a series of different target-filter assembly in order to calculate the X-ray spectra. MC...

Titanium alloys are often used in engineering fields including aerospace, cryogenic technologies, and weaponry due to their remarkable qualities. However, several issues a high coefficient of friction, weak wear resistance, low hardness hinder widespread usage. Despite efforts enhance tribology, achieving ultra-low friction on titanium alloy surfaces remains challenging problem materials scienc...

The rear interface of kesterite absorbers with Mo back contact represents one the possible sources nonradiative voltage losses (ΔVoc,nrad) because reported decomposition reactions, an uncontrolled growth MoSe2, or a nonoptimal electrical high recombination. Several intermediate layers (IL), such as MoO3, TiN, and ZnO, have been tested to mitigate these issues, efficiency improvements reported. ...

The transmembrane form of tumor necrosis factor (mTNF), expressed on activated monocytes (MO) and macrophages (MPhi), is able to induce apoptosis in human endothelial cells (EC). Apoptosis is mediated by two distinct mechanisms: direct cell contact and a yet-unidentified soluble protein, death factor X. In addition, mTNF acts as a receptor that transduces a "reverse signal" into MO/MPhi when bo...
