Toxicity has occurred in workers exposed to nickel dust or nickel carbonyl formed in refining. Increased risk of nasal and lung cancers was linked to occupational nickel exposure before current workplace safety standards were set. Activated carbon with nano holes used for removing contaminants in environment. The purpose of this work is preparation a new nano-absorber, GZ-BAKI-TAC-Ni-88, for th...

Mechanistic studies of the hydrogenolysis of aryl ethers by nickel were undertaken with (diphosphine)aryl methyl ethers. A Ni(0) complex containing Ni-arene interactions adjacent to the aryl-O bond was isolated. Heating led to aryl-O bond activation and generation of a nickel aryl methoxide complex. Formal β-H elimination from this species produced a nickel aryl hydride which can undergo reduct...

The hexagonal zinc oxide coated nickel (Ni/ZnO) nanostructure photocatalyst has successfully been prepared by the reduction of nickel chloride hexahydrate using hydrazine hydrate through the solvothermal process at 140 °C followed by surface modification of the product by the reflux method at 110 °C for 1 h. The X-ray diffraction (XRD) pattern showed that the 'as prepared' sample consists of fa...

SYNTHESIS AND HETEROALLENE REACTIVITY OF BIS(ALDIMINO)PYRIDINE NICKEL COMPLEXESIN FOUR DIFFERENT OXIDATION STATESbyBLAKE R. REED August 2016Advisor: Dr. Stanislav Groysman Major: ChemistryDegree: Doctor of PhilosophyA series of redox non-innocent bis(aldimino)pyridine ligands were synthesized. Thesewere then reacted with nickel(II) salts to form Ni[NNN]X2 complex...

Formation of C–C, C–N, and C–H bonds using three heterogeneous catalysts in the form of nickel-in-charcoal (Ni/C), nickel-on-graphite (Ni/Cg), and copper-in-charcoal (Cu/C) are described.

X-ray absorption spectra were measured for a number of nickel oxycompounds and fluorides which contain nickel with valencies in the range of 2 to 4. Information on the local structure and nature of bonding of nickel were derived using theoretical standards genmted with the FEFF code. The energies of the main Ni K-edge and the pre-edge peak were found to shift to higher values by about 1.5 and 0...

disastrous effect of nickel on spinach was discussed by number of authors but the effect of amendments like biochar with nickel on spinacea oleraceal. is not still discussed by any author of the world because biochar was used as soil amendments which play a vital role in reducing mobilization and uptake of nickel by spinach plants.  as nickel contaminated plants are very harmful for the consump...

~HE pmcess of beta-disintegration can be considered as a four-particle pmcess, i.e., a process in which four particles are created simultaneously. Thus, e.g. , the process leading to the emission of an electron can be considered as the creation of a proton, a neutrino, Rnd an electron in positive energy states, and of a neutron in a negative state. is known in nickel but it has been assigned' t...

Our research group have been working on transistion metal complexes and their activity in the biology field, especially antimicrobial and anticancer properties. Novel pseudohalide ligands with orotic acid and its metal salt Ni(II) have been synthesized and evaluated for their antimicrobial activities by disc diffusion method. The complexes have been characterized by IR, SEM, Raman, P-Xrd and UV...
