OF THESIS TRANSFORMATIONS, BIOAVAILABILITY AND TOXICITY OF MANUFACTURED ZnO NANOMATERIALS IN WASTEWTER In order to properly evaluate the ecological and human health risks of ZnO Manufactured nanomaterials (MNMs) released to the environment, it is critical to understand the likely transformation products in the wastewater treatment process and in soils receiving biosolids. To address this critic...

Self-assembly of Zn(ClO4)2 with 1,1,2,2-tetramethyl-1,2-di(pyridin-3-yl)disilane (L) as a bidentate N-donor gives rise to 3D coordination networks, [Zn(μ-OH)(L)]3(ClO4)3·5H2O (1·5H2O), of unique, 103-a srs net topology. An important feature is that two enantiomeric 3D frameworks, 41- and 43-[Zn(μ-OH)(L)]3(ClO4)3·5H2O, are interpenetrated to form a racemic two-fold 3D network with cages occupied...

To study the retaliation performance of Nitrogen and Zinc on growth, yield attributes black gram (Vigna mungo L.) During Zaid season 2021, a field experiment was carried out at agricultural research farm SHUATS, Prayagraj, to analyze influence nitrogen zinc levels growth Black gram. The conducted in randomized block design (RBD) it with Nine treatments, each treatment have three replications we...

Four nanoporous carbons prepared by direct carbonization of non-permanent highly porous MOF [Zn3(BTC)2 · (H2O)3]n without any additional carbon precursors. The carbonization temperature plays an important role in the pore structures of the resultant carbons. The Brunauer-Emmett-Teller (BET) surface areas of four carbon materials vary from 464 to 1671 m(2) g(-1) for different carbonization tempe...

Thermal reactions of MnCl(DPyP) (DPyP = 5,15-di(4-pyridyl)-10,20-diphenylporphyrin) as a metalloligand with Co(II) and Zn(II) ions in dimethylformamide led to neutral one-dimensional (1D) double chain dipyridyl-porphyrin-based porous coordination polymers (PCPs), Co3(DPyP)3·4DMF (I) and Zn3(DPyP)3·2DMF·4H2O (II). Both PCPs were structurally characterized by X-ray crystallography. Particularly, ...

Zinc borates can be used as multi-functional synergistic additives with flame retardant additives in polymers. Zinc borate is white, non-hygroscopic and powder type product. The most important properties are low solubility in water and high dehydration temperature. Zinc borates dehydrate above 290°C and anhydrous zinc borate has thermal resistance about 400°C. Zinc borates can be synthesized us...

Zinc clusters are not common for binary intermetallics with relatively low zinc content, but this work shows that zinc clustering can be triggered by lithiation, as exemplified by Ca∼30Li3+xZn60−x, P6/mmm, Z = 1, which can be directly converted from CaZn2. Two end members of the solid solution (x = 0.44 and 1.38) were established and structurally characterized by single-crystal X-ray diffractio...

The present study used a hydrothermal technique to synthesize undoped and Mn 2+ doped CdS/Zn 3 (PO 4 ) 2 semiconducting nanocomposite materials. Powder X-ray diffraction, scanning electron microscopy, UV-Vis diffuse reflectance spectrometer, Fourier transform- Infrared Spectroscopy-FT-IR, and photoluminescence techniques were employed to study structural, optical, and luminescence propertie...

Introduction of quinoa (Chenopodium willd.), a gluten-free nutritious pseudo-cereal, outside its traditional growing areas exposed it to seedling damping-off. Here, we isolated eleven phosphate-solubilizing bacteria from the rhizosphere and assessed their effect on germination seedlings growth. All isolates solubilized phosphate, produced indole3-acetic acid, hydrocyanic siderophores, ammonia. ...
