The acid/base properties of model MgO surfaces have been studied using various probe molecules with acid strengths ranging from those of carboxylic acids and alcohols to alkenes and alkanes. High-resolution electron energy-loss spectroscopy (HREELS) data show that carboxylic acids, methanol and water...
as a highly effective heterogeneous base catalyst effectively catalyzes the three component reaction of aryl aldehydes, malononitrile and α-hydroxy or α-amino activated C–H acids such as 1,3-cyclohexanedione, dimedone, 4-hydroxy-6-methylpyrone, 4-hydroxycoumarin, 1,3-dimethylbarbituric acid and ...
3. Magnesium oxide can be used as a pharmaceutical additive in the field of biomedicine, with analgesic, antidiarrheal and anti-acid properties. Preparation Method: 1. Magnesium oxide can be prepared by calcining Magnesium salts (such as Magnesium chloride and Magnesium sulfate). At high ...

molecular functions. A molecular function is achieved by activities that can be performed by individual or by assembled complexes of gene products at the molecular level. As a result of the GO Consortium annotation effort, the Gene Ontology Annotation (GOA) databasebhas become a large and ...

To avoid the increase of pH value by the addition of sodium aluminate which usually lead to the slower formation of M-S-H due to preliminary formation of brucite [32] a corresponding amount of nitric acid (HNO3, Merck, suprapur, 65%) was added. In addition, sodium nitrate was added ...

Also, two levels of base-to-acid ratio were tested to establish the interaction of basicity and MgO content on sinter strength. The results show that increasing MgO content substantially decreases sinter strength when dolomite is the MgO source. This effect is more pronounced at the higher (2.0...
Acid-base propertiesElectronegativityn-octanol oxidationThree different types of supports MgO, ZnO and Nb2O5 (basic, amphoteric and acidic, respectively) were modified with gold and silver to obtain mono- (Au) and bimetallic (Au&Ag) catalysts. The novelty was the use of several model oxides ...
