The complex [Ni{2-PyNHC(S)NP(S)(OiPr)(2)-1,5,7-N,N',S}(2)] ([NiL(I)(2)]) dissolved in tri-n-octylphosphine (TOP) is decomposed in hot hexadecylamine (HDA) to give TOP-capped Ni nanoparticles. The same procedure using [Ni{2-MeC(6)H(4)NHC(S)NP(S)(OiPr)(2)}(2)-1,3-N,S] ([NiL(II)(2)]) and [Ni{PhC(S)NP(S)(OiPr)(2)-1,5-S,S'}(2)] ([NiL(III)(2)]) leads to the formation of NiS nanoparticles with the rho...

In this paper, we used tetranuclear copper (II) Schiff base complexes, [Cu4 (μ-sal2hn) (μ-N3)2(N3)2] (1) and [Cu4 (μ-salophen) (μ1, 1-N3)2(N3)2] (2), as new precursor in solid-state thermal decomposition for the synthesis of CuO ...

we have performed a density functional theory investigation on the structural and electronic properties of pristine and nitrogen-doped tio2 anatase nanoparticles as the adsorbents for removal and degradation of hydrazine molecules in the environment. we have presented the most stable adsorption configurations and examined the interaction of hydrazine molecule with these doped and undoped nanopa...

In this research, N-doped TiO2 (N/TiO2) nanoparticles have been synthesized by a sol-gel method. N/TiO2 nanoparticle has been coated with Ag metal by photochemical method. Triethylamine, N(CH3CH2)3, have been used as precursors of Nitrogen, titanium tetraiso-propoxide (TTIP), Ti[OCH(CH3)2]4, used as precursors of titanium and Ag(NO3)2 used as precursors of Silver in synthesis of these nanoparti...

We describe the organic phase transfer of surfactant-stabilized rhodium nanoparticles previously synthesized in an aqueous solution of N,N-dimethyl-N-dodecyl-N-(2-hydroxyethyl)ammonium chloride (HEA12Cl); the addition of LiN(Tf)2 to the aqueous suspension of Rh-HEA12Cl transferred the hydrosol nanoparticles to an ionic liquid phase.

Multi-hydroxylated endohedral metallofullerenol [Gd@C82(OH)22]n nanoparticles possess the general physico-chemical characteristics of most nanoparticles. They also exhibit uniquely low toxicity and antineoplastic efficacy. In the current study, the molecular mechanisms and epigenetic characteristics of the antineoplastic action of these nanoparticles are explored. Human breast cancer MCF-7 and ...

Nitrogen-doped CeO2 nanoparticles were synthesized through a wet-chemical route. Nitrogen has been successfully incorporated into CeO2 nanoparticles and the nitrogen-doping level was also successfully controlled. The optical properties due to the different N-doping levels in CeO2 nanoparticles were characterized by UV-Vis diffuse reflectance spectroscopy (DRS), which showed a visible-light abso...

Paraffin based nanofluids are widely used as thermal energy storage materials and hold many applications in the energy industry. In this work, equilibrium and nonequilibrium molecular dynamics simulations are employed to study the thermal properties of the mixed nanofluids of n-octadecane and Cu nanoparticles during phase transition. Four different nanofluids systems with different mass ratios ...

Surface properties are often hypothesized to be important factors in the development of safer forms of nanomaterials (NMs). However, the results obtained from studying the cellular responses to NMs are often contradictory. Hence, the aim of this study was to investigate the relationship between the surface properties of silica nanoparticles and their cytotoxicity against a murine macrophage cel...
