Usually this is done by content of alkali metal oxides.① Alkali glass fiber, content of alkali metal oxide is higher than 12%; ② medium-alkali glass fibers, alkali metal oxide is in a range of 6% ~12%; ③ low-alkali glass fiber, alkali metal oxide is in a range of 2% to 6%;...
Variations in dilute-acid (partial digest) metal concentrations in bottom sediments from 49 stations on the Mississippi, Alabama and Florida continental margin are investigated with the aid of ordination and other multivariate statistical techniques. Total iron, carbonate content, clay fraction and water...
A method for the preparation of halogen benzoic acids by oxidation of the corresponding nuclear halogenated toluenes with oxygen or a gas containing oxygen, in acetic acid, with the addition of soluble cobalt and/or manganese compounds, and of sodium bromide, at elevated temperatures of about 80...

acid catalyst to the agglomerate and performing a secondary reaction to prepare a metal oxide-silica composite wet gel (step 2); and drying the metal oxide-silica composite wet gel (step 3), wherein the metal ion solution of step 1 includes a first acid catalyst, and the second water ...
with 6 M HCl in a 1:1 ratio, until full dissolution of the framework or oxide occurred. If the Fe(II) concentrations was large, the sample was further diluted with 1 M HCl. All samples were analyzed for Fe(II) using the ferrozine assay62. The ferrozine assay was performed by ...
The effects of sulfuric acid on metal depend on the type of metal, the concentration of the acid, and the temperature. If the acid...
Where any of R1 through R8 of any of the foregoing adducts or adduct metal complexes has a free CO2H group, that moiety can be reacted with an amino acid moiety, which can be a monoclonal antibody, to form an amide. Example D is illustrative of such reactions: ...
Metal-based nitrides have been extensively explored as an alternate to oxide photocatalysts to find the appropriate outlet with high quantum efficiency. A recent increasing trend in photocatalytic solar fuel research has switched the attention of researchers to 2D nitrides due to their attractive features...
