polyacrylamide for acidophilic water systems.If matched with PAC, aluminum sulphate, the effect will be excellent. 3 Metallurgical Mineral Dressing In floatation and smelting of Zinc, manganese and copper mines, its leachate and slag can be added into PAM to improve the ...
In these regions we observed an increase in crystallinity, which was probably due to the decrease in the molecular weight of PE. The high oxidation was probably due to the modifications induced by the material treatment. select article An EPR study of VO2+ ions in arsanilic acid [C6H4AsNO...
Hematopoiesis can occur outside of the bone marrow during inflammatory stress to increase the production of primarily myeloid cells at extramedullary sites; this process is known as extramedullary hematopoiesis (EMH). As observed in a broad range of hema
A fascinating crown-porphyrin (Cr-Pr) complexes are investigated with doping potassium (K atom) on the crown ether face and introducing zinc (Zn atom) on the porphyrin face. Significantly, the crown ether ring is doped with K atom, the second-order nonlinear optical properties of the complexes...
Specified orthoesters are the p orthoformic acid methyl and ethyl esters; Specified Lewis acids are zinc and aluminium chlorides, tin tetrachloride, boron trifluoride, boron trifluoride-diethyl ether adduct; specified alkyl esters of mineral acids are dimethyl sulphite and sulphate; tri-isopropyl borate...
Structure elucidation of unknown small molecules by mass spectrometry is a challenge despite advances in instrumentation. The first crucial step is to obtain correct elemental compositions. In order to automatically constrain the thousands of possible ca
Protein kinases (PKs) have emerged as one of the most intensively investigated drug targets in current pharmacological research, with indications ranging from oncology to neurodegeneration. Tau protein hyperphosphorylation was the first pathological post

Aβ peptide is majorly implicated in the production of reactive oxygen species (ROS) inside the brain. The coordination of Aβ peptide with metal ions such as copper, zinc and iron has been widely established in context with the formation of ROS [7]. During metal catalysed oxidation, hydrogen...
A process is disclosed for preparing mixtures of low molecular weight polyhydroxyl compounds and hydroxyaldehydes and hydroxyketones by condensing formaldehyde hydrate with itself in the presence of (I) as catalyst a soluble or insoluble compound of a metal of the first to eighth sub-group or seco...
