The application of natural deep eutectic solvents (NADES) in the pharmaceutical, agricultural, and food industries represents one of the fastest growing fields of green chemistry, as these mixtures can potentially replace traditional organic solvents. Th

The Xiaokele Cu (–Mo) deposit is a newly discovered porphyry deposit in the northern Great Xing’an Range (GXR) of northeast China. The multiphase hydrothermal superposition on the Xiaokele Cu (–Mo) deposit obscures temporal relationships between quartz veins/veinlets in different mineralization ...
In addition, it promotes the chlorination of aromatic substrates [55]. It has recently been shown that iron trichloride, which is often used for coagulation in water treatment, can lead to the formation of organoiodine compounds if the treated water contains reactive substrates (such as ...
2,5-Dihydroxy-[1,4]-benzoquinone (DHBQ, 1) is the most prominent representative of cellulosic key chromophores, which occur almost ubiquitously in all types of aged cellulosics. The degradation of DHBQ by chlorine dioxide under conditions of industrial pulp bleaching (“D stage”) was studied,...
NMR samples were prepared by dissolving the oligonucleotides in H2O/D2O 90/10, lithium cacodylate 10 mM, pH 7.4 to get a oligonucleotide final concentration of 270 μM. Ammonium acetate or potassium chloride were progressively titrated in to a final cation concentration of 150 mM. NMR data were...
Black particles may also be formed by staining latices with metal oxides, such latex copolymers consisting of any of butadiene, styrene, isoprene, methacrylic acid, methyl methacrylate, acrylonitrile, vinyl chloride, acrylic acid, sodium styrene sulfonate, vinyl acetate, chlorostyrene, dimethylaminopropyl...
Water oxidation and concomitant dioxygen formation by the manganese-calcium cluster of oxygenic photosynthesis has shaped the biosphere, atmosphere, and geosphere. It has been hypothesized that at an early stage of evolution, before photosynthetic water
SEM for (a) Micromax and (b) perlite at 10 µm. Full size image Six drilling formulations were prepared in this work, they consist of several additives with specific function per each. Water used as a continuous phase and defoamer to inhibit the form of foams. Sodium carbonate function ...
sodium chloride brine. The solution was then divided into two portions. To one portion enough volume of a chromium malonate solution was added to bring the chromium content to 200 mg/l. To the other portion a volume of brine equivalent to the volume of crosslinker solution was added. The ...
