Olfactory receptors were found to be expressed also in human sperm giving rise to the hypothesis that they might play a role in fertility and sexual behavior. For instance, bourgeonal was demonstrated to be an agonist of sperm cells olfactory receptor, OR1D2. OR1D2 has been found to be expressed...

Publisher SummaryThis chapter discusses elimination reactions. An organic molecule undergoes an elimination reaction when it loses two atoms or groups of atoms that are subsequently not replaced. Most frequently, the fragments are removed from the adjacent atoms and the processes are called beta...

Two assay methods for antipyrine (AP) and its main metabolites 3-hydroxymethylantipyrine (3-HMA), norantipyrine (NORA) and 4-hydroxyantipyrine (4-HA) in urine samples have been compared. Method I involved a 3 h incubation at 37°C with β-glucuronidase, whereas method II used acid hydrolysis wit...

It had previously been shown that D-phenylalanine and hydrocinnamic acid, two in vitro inhibitors of carboxy-peptidase A, possess an analgesic action when injected i.p. in mice. We have studied the in vivo effects of indole-3-acetic acid, another carboxypeptidase A inhibitor, and of the followin...

The synthesis and complete characterisation of the fluorescent ligand, 4-acridinol-1-sulphonic acid (the acridine analogue of 8-quinolinol-5-sulfonic acid) is described. Using a judicious array of nuclear magnetic resonance spectroscopy experiments, the structural elucidation and full assignment...

Alternating conventional radical copolymerization of tert-butyl-2-trifluoromethacrylate (a non-homopolymerizable fluoromonomer under radical conditions) with vinyl acetate, initiated by 2,2′-azo-bis(4-methoxy-2,4-dimethyl valeronitrile) at 40 °C is presented. The study of the kinetics of the c...

Wider plastic applications of poly(vinyl chloride) (PVC) has raised serious problem to the environment. Since (PVC) waste products resist biodegradation and persist in the environment for longer time. The object of this study is to blend (PVC) with biodegradable cellulose acetate to thermally su...

The capacity of pharmaceutical pollution to alter behaviour in wildlife is of increasing environmental concern. A major pathway of these pollutants into the environment is the treatment of livestock with hormonal growth promotants (HGPs), which are highly potent veterinary pharmaceuticals that e...

Two novel C-2 position modified 8-hydroxyquinoline ligands, (E)-2-[(4-tert-butylphenyl)ethenyl]-8-hydroxyquinoline (L1) and (E)-2-[(2-chloro-3,4-dimethoxyphenyl)ethenyl]-8-hydroxyquinoline (L2) as well as their zinc(II) and cadmium(II) complexes, namely Zn2(L1)4, Cd3(L1)6, Zn3(L2)6 and Cd3(L2)6 ...

Properties of supporting electrolytes and solvents were examined for use with vanadium acetylacetonate – a member of the class of metal(β-diketonate) active species – in non-aqueous redox flow batteries. Twenty supporting-electrolyte/solvent combinations were screened for ionic conductivity a...

In this paper, the efficiency of catalysis of nickel acetylacetonate in the thermal cure and ceramization of a new liquid polymeric precursor (methyl-terminated vinyl-containing oligomethylsilane, PSI) of SiC was investigated. The new liquid PSI was prepared by Wurtz condensation method using li...

In this work, the V2O3 nanoparticles (NPs) with ultrathin carbon shells were synthesized by a facile solvothermal process. The V2O3 NPs were about 30 nm and contained a carbon shell of about 2 nm thick. The V2O3 NPs were homogeneously dispersed and loosely packed. When used as anode material, th...

Addressed herein is the preparation and the electrode performance of monodisperse CoFe2O4 nanoparticles (NPs) supported on Vulcan XC-72 for the Lithium-air battery (LAB) and Lithium-ion battery (LIB). Monodisperse CoFe2O4 NPs were synthesized by the thermal decomposition of cobalt(II) acetylacet...

Transition metal vanadate material has attracted many battery researchers due to its layered type structure enabling facilitated lithium ion insertion/extraction and ability of vanadium to exist in multiple valence states. Cobalt vanadates have been receiving much research attention as superior ...

Herein, nickel carbide (Ni3C) nanoparticles were controlled synthesized by decomposing nickel acetylacetonate in oleylamine and oleic acid solvent at a comparatively low temperature of 280 °C. The resultant Ni3C nanoparticles with an average size of 18 nm exhibited large specific surface area a...

Electron transport layer (ETL) plays an important role in improving charge transportation, suppressing current-voltage hysteresis and enhancing photovoltaic performance of perovskite solar cells (PSCs). Here we successfully synthesize anatase titania nanoparticles (TiO2 NPs) with an average diam...

With the purpose to settle the aggregation and conductivity issues of the active materials, the metal disulfides (MS2, M = Fe, Co) nanoparticles in-situ encapsulated by amorphous carbon layers (MS2@C) have been synthesized by directly vulcanizing the iron (III) acetylacetonate or cobalt (II) ace...

The infinite dilution binary diffusion coefficients D12 of lithium acetylacetonate were measured in supercritical carbon dioxide by the chromatographic impulse response (CIR) method at 308.15–333.15 K and pressures up to 36.00 MPa. The D12 values were also measured in liquid ethanol at 298.15–...

Infrared, ultraviolet, and nuclear magnetic resonance spectroscopies have been used to obtain quantitative data to establish the nature of bonding in alkali and alkaline earth acetylacetonates. Most of these acetylacetonates are salt-like; however the properties of lighter metal complexes reflec...

The electrochemical transformations of 2,3-butanedione(biacetyl) and 2,3-butanediol were studied in acid media at platinized platinum electrode. It has been shown that the main end product in the biacetyl reduction is butane. The first step of the reduction is the formation of acetoine. The furt...
