MgO is an important inorganic material, which can be used in many aspects, such as catalyst, toxic-waste remediation agent, adsorbent, and others. In order to make use of MgO, nano-MgO was prepared by ultrasonic method using Mg (CH3COO)2.2H2O as precursor, NaOH aqueous solution as precipitant in this paper. Effect factors on MgO nano-particle size were investigated. Characteristics of samples w...
OBJECTIVES/HYPOTHESIS Low pH, hydrogen peroxide generation, and the hyperosmolarity mechanisms of antimicrobial action are ubiquitous for all honeys. In addition, manuka honey has been shown to contain high concentrations of methylglyoxal (MGO), contributing the relatively superior antimicrobial activity of manuka honey compared to non-MGO honeys. In high concentrations, manuka honey is effecti...
Diabetes mellitus is characterized by hyperglycemia and excessive production of intermediary metabolites including methylglyoxal (MGO), a reactive carbonyl species that can lead to cell injuries. Interacting with proteins, lipids, and DNA, excessive MGO can cause dysfunction of various tissues, especially the vascular walls where diabetic complications often take place. However, the potential v...
in this work firstly fe3o4 nanoparticles were synthesized via a sono-chemical method. at the second step magnesium hydroxide shell was synthesized on the magnetite-core under ultrasonic waves. for preparation fe3o4-mgo the product was calcinated at 400 ºc for 2h. properties of the product were examined by x-ray diffraction pattern (xrd), scanning electron microscope (sem) and fourier transform ...
Interfacial properties of 5 nm MgO(001)/7 nm Fe(001)/1.8 nm MgO(001)/t nm Cu-phthalocyanine (CuPc) hybrid multilayers with t = 0, 1, 7, and 10 were investigated by using x-ray photoemission spectroscopy (XPS). Rather sharp interfacial properties were observed in the CuPc films grown on an epitaxial MgO/Fe/MgO(001) trilayer than a MgO/Fe(001) bilayer. This work suggests a new way to improve devi...
