DESIGN OF FIRST-ROW TRANSITION METAL BIS(ALKOXIDE) COMPLEXES AND THEIRREACTIVITY TOWARD NITRENE AND CARBENE TRANSFERbyJAMES A. BELLOWAugust 2016Advisor: Dr. Stanislav GroysmanMajor: Chemistry (Inorganic)Degree: Doctor of PhilosophyThe novel alkoxide ligand [OCtBu2Ph], or [OR], was synthesized in a single step as a lithium salt.It was then reacted ...

Nickel phosphide-embedded graphene, prepared by the hydrothermal reaction of red phosphorus, nickel chloride, and graphene oxide in a mixture of ethylene glycol-water, is investigated as the counter electrode of DSSCs. It is demonstrated that the DSSC with the nickel phosphide-embedded graphene as the new counter electrode presents an excellent performance competing with that of the Pt electrode.

Nickel is an essential trace element. Nickel and its compounds have many industrial applications. Concern about nickel compounds is due to potential occupational and environmental health hazards. In the present study the mutagenic potential of nickel chloride (NiCl ) was tested to evaluate somatic and heritable 2 disorders which may extend to the next generations and associated with increased r...

Some of the component metals of the alloys used for total joint prostheses are toxic and dissolve in the body fluids. It is important to establish how toxic these metals are and to assess the risk of localised tissue necrosis around the prostheses. This has been investigated by incubating primary monolayer cultures of human synovial fibroblasts with various preparations of metals for periods up...

BACKGROUND Patch testing is an essential procedure in the investigation of eczema in children. OBJECTIVES To analyse the frequency of contact hypersensitivity and allergic contact dermatitis among Polish children with eczema. PATIENTS/METHODS During an allergy screening programme involving 9320 children aged 7 and 16 years, 12.6% reported symptoms of chronic/recurrent eczema. From this grou...

We report on the optical and magneto-optical response of hybrid plasmonic lattices that consist of pure nickel and gold nanoparticles in a checkerboard arrangement. Diffractive far-field coupling between the individual emitters of the lattices results in the excitation of two orthogonal surface lattice resonance modes. Local analyses of the radiation fields indicate that both the nickel and gol...

Adverse effects of manufactured nickel oxide nanoparticles on the microalgae Chlorellavulgaris were determined by algal growth-inhibition test and morphological observation via transmission electron microscopy (TEM). Results showed that the NiO nanoparticles had severe impacts on the algae, with 72 h EC(50) values of 32.28 mg NiOL(-1). Under the stress of NiO nanoparticles, C. vulgaris cells sh...

We describe the use of surface-deposited nickel nanoparticles to enhance the fluorescence signatures of fluorophores. Different density Ni nanoparticulate substrates were fabricated and characterized using both AFM and optical absorption techniques. When fluorophores were placed in close proximity to the substrates, metal-enhanced fluorescence (MEF) was observed. The wavelength dependence of th...

Nickel and cadmium are heavy metals with some hazards for plant metabolism. The impacts of nickel chloride (0, 400 and 800 μM) in the presence of vitamin B complex (0, 30 and 60 ml from pharmacy commercial stock) and the impacts of cadmium chloride (0, 100, 200, 300, 400, 500 and 600 μl from 100 µM stock) in pot and cadmium nitrate (0, 100, 200, 400, 800, 1600 and 3200 μl from 100 µM stock) in ...
