A Ni/meso-MgO catalyst with high surface area and small Ni nanoparticles was synthesized and investigated for hydrogen production by steam reforming of phenol for the first time. Compared to conventional Ni/MgO, the Ni/meso-MgO catalyst showed higher catalytic activity and stability. X-ray Diffraction, N2 adsorption, hydrogen temperature programmed reduction, transmission electron microscopy an...

Antibacterial activity of honey is due to the presence of methylglyoxal (MGO), H2O2, bee defensin as well as polyphenols. High MGO levels in manuka honey are the main source of antibacterial activity. Manuka honey has been reported to reduce the swarming and swimming motility of Pseudomonas aeruginosa due to de-flagellation. Due to the complexity of honey it is unknown if this effect is directl...

Recent studies have reported increases of methylglyoxal (MGO) in peritoneal dialysis patients, and that MGO-mediated inflammation plays an important role in the development of peritoneal fibrosis through production of transforming growth factor-β1 (TGF-β1). Linagliptin, a dipeptidyl peptidase-4 inhibitor, exerts anti-inflammatory effects independent of blood glucose levels. In this study, we ex...

The purpose of this study was to investigate the effect of modifying aluminum oxide slips with magnesium oxide (MgO) to create a jointing material for In-Ceram Alumina. Jointed In-Ceram Alumina bars with In-Ceram Alumina slips containing 0-1.0 mass% MgO were examined by a three-point bending test. Joint-free bars were also tested as controls. Fracture surfaces were evaluated by scanning electro...

Calculation of the tunneling magnetoresistance ~TMR! of an epitaxial Fe/MgO/Fe~001! junction is reported. The conductances of the junction in its ferromagnetic and antiferromagnetic configurations are determined without any approximations from the real-space Kubo formula using tight-binding bands fitted to an ab initio band structure of iron and MgO. The calculated optimistic TMR ratio is in ex...

Dolomite [CaMg(CO3)2] is an intolerable impurity in phosphate ores due to its MgO content. As high grade phosphate reserves become depleted, the need to develop a cost effective method for the removal of dolomite from high-MgO phosphate ores becomes increasingly important. The jigging process has been investigated as a method for the beneficiation of high-MgO sedimentary phosphate ores. A labor...

Pulsed laser deposition method was employed to grow MgO thin films with preferred orientation on bare Si(100) and SiO2/Si(100) substrates. The orientation of MgO thin films was systematically investigated by varying deposition parameters. XRD analysis showed that the preferred orientation of MgO thin films would change from (111) to (100) when laser fluence decreased and oxygen pressure increas...

Photoelectron spectra of MgO n n 1 5 reveal a surprising trend: The electron binding energy decreases from n 1 to 4, and then increases from 4 to 5. Ab initio calculations suggest this pattern is related to the electrostatic interaction between the extra electron and the charge distribution of the neutral cluster. This interaction is significant in MgO and MgO 2 5 , for which the lowest nonvani...

Various theories have been proposed to explain the hyperglycaemia-induced pathogenesis of vascular complications of diabetes, including detrimental effects of AGEs (advanced glycation end products) on vascular tissues. Increased formation of the very reactive dicarbonyl compound MGO (methylglyoxal), one of the side-products of glycolysis, and MGO-derived AGEs seem to be implicated in the develo...
