The depletion of fossil fuels has caused the price of petroleum to rise remarkably and created need for alternative energy such as biodiesel. In the present study, the biodiesel was produced from castor oil using ferromagnetic zinc oxide nanocomposite as heterogeneous catalyst for transesterific...

Male rats of 80–90 g that were fed 42 days with a commercial rodent diet of 2780 kcal/100 g and received chronic overloads of either Fe(II) or Cu(II) in the drinking water. The two metals produced brain oxidative stress and damage with marked increases in the indicators of oxidative processes: ...

Fe(II) oxidation processes at the surfaces of bacterially colonized iron deposits are examined at three hot springs in Japan for which the chemical profiles of the pH, redox, and O2 and Fe(II) concentrations at the water/deposit interface are measured via microelectrodes. The three hot springs s...

The microwave-assisted macrocyclization reaction of 2,3-bis[2-(morpholin-4-yl)ethylsulfanyl]-(2Z)-butene-1,4-dinitrile led to novel symmetrical iron(II) sulfanyl porphyrazine. Novel macrocycle was carefully characterized using UV–vis, MS, NMR, and FTIR. The electrochemical and spectroelectroche...

The effect of initial pH, metal oxide and concentration of nanoparticles (NP) on hydrogen production were investigated in batch assays using glucose-fed anaerobic mixed bacteria in thermophilic condition of 60 °C. Two type of metal oxide nanoparticles, iron (II) oxide and nickel oxide, were tes...

The effects of different parameters including nanoparticles mass fraction and temperature were investigated on rheological behavior and surface tension of iron(II) oxide/light crude oil nanofluid. Iron(II) oxide was dispersed in light crude oil by using ultrasonic processor. TEM images was provi...

The effect of Co doping on structural, optical and magnetic behavior of pure and Co doped Zinc stannate (ZTO) nanostructures was investigated. Pure and Co (1%, 3% & 5%) doped Zn2SnO4 compounds were prepared through simple precipitation route. Formation of cubic inverse spinel structure and metal...

A series of La2CoxSn2−xO7−δ oxides with pyrochlore structure have been synthesized by the co-precipitation method as high-temperature catalysts for methane combustion. The dopant strongly influences the thermal stability and redox properties of these pyrochlores. IR measurements show that the S...

Co−doped stannates, Zn2-xCoxSnO4 (0.5 ≤ x ≤ 1.5), were produced by ceramic synthesis starting from the ZnSnO4 phase. Morphology, structure, and composition of synthesized compounds were examined using scanning electron microscopy, X-ray diffraction analysis (XRD), and X-ray photoelectron spect...

Inorganic pigment firm Shepherd Color has added a new cobalt-based blue pigment to its range of Arctic® infrared-reflecting colours. Compared with previous red-shade blues, Blue 10C595 is said to have significantly lower surface area and resin demand, which results in higher gloss.

Two novel cobalt-azido compounds [Me4N]2[NaCo(EE-N3)6] 1 and [Ph4P]2[Co(N3)4] 2; where Me4N = tetramethyl ammonium ion, EE = end-to-end, Ph4P = tetraphenyl phosphonium ion, have been synthesized and characterized by single crystal X-ray crystallography. Two compounds were synthesized by varying ...

In this work describes the cobalt-beta hydroxyl benzoate (Co-bhb), Cobalt based complex has been synthesized by solvothermal method and verified for the application detection and removal of environmentally hazardous molecule like methylene blue. The Co-bhb sample were characterized by various te...

Cobalt-blue colorant was first used in the 18th Dynasty in the New Kingdom of Egypt. The source of this cobalt was cobaltiferous alum from the Western Oases of Egypt. The use of this alum, especially in glass, was suddenly limited at the end of the 18th Dynasty. There is little evidence of the p...

Cobalt blue is an inorganic pigment with an intense blue color, and consists mainly of cobalt aluminate (CoAl2O4) spinel. Many synthesis methods for cobalt blue have been reported, but there are no reports on the color tone of cobalt blue synthesized from different starting materials. Thus, the ...

Owing to the scarcity in nature of cobalt ores and the disadvantages of cobalt blue prepared via traditional solid-phase method, the high cost of cobalt blue pigment severely restricted their wide application in the relevant fields. Here, sepiolite was employed to fabricate the bright blue cobal...

The influence of cerium oxide nanoparticles on singlet oxygen generation upon photosensitizer irradiation was studied. Solutions of tetra-15-crown-5-phthalocyanines (aluminium(III), gallium(III) and indium(III) hydroxide, 1Al, 1Ga, 1In) in DMSO were used as photosensitizers.Ceria nanoparticles (...

:The present study demonstrates the synthesis of cerium oxide nanoclusters (CeO2-NC) and its application towards detection of reactive oxygen species (ROS). ROS are generated due to exogenous exposure to oxidants, car smoke, pollutants etc. as well as endogenously as a byproduct of metabolism th...

Polycrystalline cerium oxide thin films (15 nm) deposited on a glassy carbon substrate were used as an electrode in a mediator-free, non-enzymatic electrochemical sensor for hydrogen peroxide. The electrode surface was characterized by X-ray photoelectron spectroscopy, resonant photoelectron spe...

Diesel/cerium oxide nanofluid fuel was a high-energy-density fuel with addition of highly exothermic NPs, and its combustion performance was better than conventional fuels.
