Carbon materials have enjoyed wide applications in supercapacitors because of their high surface area which guarantees a high power output through the formation of an electric double layer (EDL). However the energy stored by this EDL mechanism is often insufficient and as such there is the need ...

In this work, we investigate the photolysis behavior of 2,3-dibromo-5,6-dimethyl-1,4-benzoquinone (DDBQ), the only dibrominated benzoquinone detected in treated water so far. DDBQ solutions prepared in ultra-pure water were exposed to UV radiation centered at 254 nm (UV254), and the photolysis o...

B-Alkylpinacolboranes, derived from rhodium-catalyzed hydroboration of allyl ethers with pinacolborane, react with 1,4-benzoquinone under acidic, oxidizing conditions, to afford, after subsequent hydrogenation, 2-substituted hydroquinones in isolated, purified yields of about 50% based on 1,4-be...

Hematotoxicity of benzene is derived mainly from its active metabolite, 1,4-Benzoquinone (1,4-BQ), which induces cell apoptosis and mitochondrial damage. Damaged mitochondria are degraded through a specialized autophagy pathway, called mitophagy, which is driven by PINK1/Parkin signaling. Howeve...

The photochemical reactions in the aqueous solutions of 1,4-benzoquinone, 2-methyl-1,4-benzoquinone, 2,6-dimethyl-1,4-benzoquinone, 2-chloro-1,4-benzoquinone, 2,5-dichloro-1,4-benzoquinone and 2,6-dichloro-1,4-benzoquinone were investigated using three independent monitoring techniques (spectrop...

The monoamine oxidase (MAO) enzymes are of considerable pharmacological interest and inhibitors are used in the clinic for the treatment of major depressive disorder and Parkinson's disease. A limited number of studies have shown that the quinone class of compounds possesses MAO inhibition ...

Effective regulation of p-phenylenediamine (PPD), a widely used precursor of hair dye that is harmful to human health in large concentration, relies upon an accurate yet simple detection of PPD. In this context, amperometric electrode sensor based on perovskite oxide becomes attractive given its...

Superhydrophobic surfaces have attracted great attention for their distinguishing properties. The key factor for a surface to achieve superhydrophobic is the intrinsic hierarchical structure. Traditional graphene based materials are not suitable for the construction of hierarchical structures be...

Hybrid supercapacitors using metal–organic frameworks (MOFs) exhibit high power and remarkable rate capability with consistent cyclability. The key limitations in developing MOF supercapacitors are the limited number of ligands and extensive laboratory protocols for synthesis. To solve these pr...

To enhance the performance of electrorheological (ER) fluid, jellyfish-shaped p-phenylenediamine functionalized graphene oxide-g-polyaniline fiber (PPDG-g-PANI) nanocomposite particles were fabricated using an interfacial polymerization method. Their thermal stability was tested via a thermograv...

Textile fabrics made up of cotton, wool, and polyethylene terephthalate (PET) were coated with poly(catechol) and poly(p-phenylenediamine) through the in situ enzymatic polymerization of catechol and p-phenylenediamine, assisted by laccase under high-pressure homogenization. All coated fabrics s...

In the current study, we demonstrate a low cost approach for the facile synthesis of Cu and Cu-CuO nanocomposite by a chemical reduction method. By tuning the chemical constituent in the reaction, we can effectively synthesise metal-semiconductor (Cu-CuO) nanocomposite through this method. The s...

Aqueous micellar solutions of cationic gemini surfactants belonging to 12-s-12 series (where s = 4, 5, 6) in presence of p-toluidine (PTD) exhibit a noticeable micellar growth/transition from viscometric and scattering studies. The dynamic light scattering (DLS) and small angle neutron scatterin...

The charge transfer complexes of the donor p-toluidine with π-acceptor picric acid have been studied spectrophotometrically in various solvents such as carbon tetrachloride, chloroform, dichloromethane acetone, ethanol, and methanol at room temperature using absorption spectrophotometer. The re...

A bacterium, which utilizes p-toluidine as sole source of carbon and energy was isolated from soil. The bacterium was identified as Pseudomonas testosteroni.From enzymatic studies we propose the following pathway for the degradation of p-toluidine:p-toluidine is oxidatively converted to 4-methyl...

The Cu(II), Zn(II), Cd(II), and Hg(II) bromide complexes of p-toluidine have been studied with B3LYP calculations by using def2-TZVP basis set at the metal atoms and using def2-TZVP and 6-311G+(d,p) basis sets at the remaining atoms. Both basis set combinations give analogous results, which vali...

The observation of triplet–triplet absorption of salicylidene-p-toluidine, is complicated by the possible colored isomer formation during the optical pumping. The short-lived (singlet–singlet) and long-lived (triplet–triplet) absorption spectra were recorded phographically by microsecond flas...

The effect of p-toluidine (PTD) on the growth of cationic surfactant micelles in aqueous solutions was examined by viscosity, UV–visible spectroscopy, dynamic light scattering (DLS), 1H NMR and nuclear Overhauser effect spectroscopy (NOESY). Viscosity and scattering results are used to follow t...
