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...

Polymer composite of heat cure acrylic (PMMA) matrix reinforced with different weight nanoparticles Hydroxyapatite and Magnesium Oxide (1, 5 10% wt.) were prepared by hand molding technique. The oxide synthesized Simple Chemical Method (Co-precipitation). structure morphology properties MgO examined X-ray diffraction (XRD), Field Emission Scanning electron microscopy (FESEM) EDX. Lattice consta...

The consequences of climate change, and the increased accumulation metalloids, like arsenic (As), in environment, are significantly affecting crop performance yield. Arsenic interferes with various plant biochemical physiological processes, which result diminished growth development. Magnesium oxide nanoparticles (MgO-NPs) can improve contribute to tolerance heavy metal/metalloid toxicity. Duri...

This study investigated how the inclusion of magnesium oxide (MgO) maintained tablet hardness during storage in an unpackaged state. Tablets were prepared with a range of MgO levels and stored at 40°C with 75% relative humidity for up to 14 d. The hardness of tablets prepared without MgO decreased over time. The amount of added MgO was positively associated with tablet hardness and mass from an...

This study investigated the effects of Fe-soy proteinate (Fe-SP) and magnesium oxide (MgO) dietary supplements on eggshell quality in laying hens. A total of 800 26-wk-old Hy-Line Brown hens were assigned to four dietary treatments: control (C), FeSP 100 (100 ppm Fe-soy proteinate), MgO (3 g MgO/kg diet), and Fe-SP 100+MgO. Each treatment had five replicates of 40 hens. The FT-IR (Fourier trans...

Nano SiO2 and MgO particles were incorporated into β-tricalcium phosphate (β-TCP) scaffolds to improve the mechanical and biological properties. The porous cylindrical β-TCP scaffolds doped with 0.5 wt % SiO2, 1.0 wt % MgO, 0.5 wt % SiO2 + 1.0 wt % MgO were fabricated via selective laser sintering respectively and undoped β-TCP scaffold was also prepared as control. The phase composition and me...

Methylglyoxal (MGO) is a reactive dicarbonyl metabolite of glucose, and its plasma levels are elevated in patients with diabetes. Studies have shown that MGO combines with the amino and sulphhydryl groups of proteins to form stable advanced glycation end products (AGEs), which are associated with vascular endothelial cell (EC) injury and may contribute to the progression of atherosclerosis. In ...

We report scanning tunneling spectroscopy studies of the electronic structure of 1.5–3 nm 001 textured MgO layers grown on 001 Fe. Thick MgO layers exhibit a bulklike band gap, 5–7 eV, and sparse, localized defect states with characteristics attributable to oxygen and, in some cases, Mg vacancies. Thin MgO layers exhibit an electronic structure indicative of interacting defect states forming ba...
