The sorghum grasses have the capability to accumulate silica in the form of silicic acid, which can be transformed into amorphous rigid silica with an impressive purity of 95-96%, commonly known as micro-silica phytoliths, through a chemical extraction process by using acid or base hydrolysis ...
The improved catalytic activity was reported to be due to high basicity of rehydrated solids having strong and appropriate basic sites with possible inter layer hydroxide anions at the edges of the crystals. Other metal-based heterogeneous catalysts with different experimental conditions for the ...
[158] developed a novel carboxylic acid-functionalized layered double hydroxide (LDH) metal–organic framework, LDH/MOF nanocomposite using an in-situ green synthesis technique and tested it for the removal of Cd (II) and Pb (II). The MOF crystals (UiO-66-(Zr)-(COOH)2) of nanometer size...
Here, we show the design and synthesis of a Cu(II) metal-organic framework (FJI-H14) with a high density of active sites, which displays unusual acid and base stability and high volumetric uptake (171 cm3 cm−3) of CO2 under ambient conditions (298 K, 1 atm), making it a...
citric acid ⇦ this on eBay or Amazon [affil links] sodium dichromate My problem is I how I can know how much chem I am using on my pieces in the nickel bath; I don't have problems on nickel because the nickel metal is fixed on the metal base, and same with C.C.T. But ...

resulting in the generation of potent oxidizing agents hypochlorous acid (HClO) and singlet oxygen (1O2). These reactive oxygen species (ROS) have the capability to destroy proteins, nucleic acids, and other vital biomolecules, leading to destructive effects on microorganisms or tumor cells. ...
a process for producing the above-mentioned alkoxycarbonylalkylthioaryl compound, which process comprises reacting the above-mentioned disulfide compound with the above-mentioned hydroxide of an alkali metal M 1 in the presence of the above-mentioned sulfur compound to obtain an alkali metal salt of...
Alumina (Al2O3) and its transition phases, e.g., g-Al2O3 and a-Al2O3 with high thermal stability (up to ≈ 1000 °C), have widely been used in the adsorption process because of their beneficial textural properties as well as acid/base characteristics [325,341,342]. Monolithic honey...
On the other hand, the hole can directly react with water to form hydroxide radicals [119,120]. The reaction is described in Equations (9)–(12). In particular, ROS has the ability to effectively destroy the proteins and nucleic acids of pathogenic microorganisms [112], so that many ...
