the Brown glaze porcelain is one of the main production for the Yaozhou kiln in the Northern Song Dynasty (960–1127 A.D). To clarify the colouring mechanism of the brown glaze is a key to understand the technology development of the Yaozhou kiln in the 11th century. In order to determine the pr...

In the present work, graphene oxide (GO) was synthesized through modified Hummer's method and the covalent functionalization of GO was achieved via amino moiety using N,N′-dicyclohexylcarbodiimide (DCC) as coupling agent and ethylenediamine (EDA) & 1,3-diaminopropane (DAP) as amino precurs...

The potential of pennywort (Hydrocotyle vulgaris) for phytoremediation of C.I. Acid Blue 92 (AB92) was evaluated.

Removal of C.I. Acid Blue 92(AB92) dye by exfoliated graphite (EG) was investigated. Batch adsorption test results proved that EG can remove the dye with a minimum removal efficiency of 70%. Equilibrium isotherm was analyzed by Freundlich, Langmuir, and Radke–Prausnitz models and the related pa...

This paper is concerned with the surface treatment of copper phthalocyanine blue (C.I. Pigment Blue 15:3) by adsorption with poly(ethylene glycol)s of various molecular weights. The results from the experiments show that the contact angle for water, the flowability and the mean diameter of treat...

The indirect cathodic reduction of the vat dye indigo (C.I. Vat Blue 1) by cathodically reduced Lawsone (2-hydroxy-1,4-naphthoquinone; C.I. Natural Orange 6) was studied in aq. solution at different pH values. Cyclic voltammetry and spectroelectrochemistry were used to investigate the electroche...

The photocatalytic degradation of a dye derivative, C.I. disperse blue 1 (1), has been investigated under UV light irradiation in the presence of TiO2 and H2O2 under a variety of conditions. The degradation was studied by monitoring the change in substrate concentration employing UV spectroscopi...

P-type tin monoxide (SnO) decorated TiO2 nanoparticles have been synthesized by the powder atomic layer deposition (p-ALD) method in a fluidized bed reactor at 150–250 °C. Successful deposition of SnO on a TiO2 surface was realized using a precursor combination of Sn(dmamp)2 and H2O as Sn sour...

A blue direct diode laser metal deposition system, which uses multiple lasers, was developed to realize a high-quality coating layer with a dense, fine structure and high purity. To clarify the formation mechanism of the pure copper layer, the formation process using a blue direct diode laser sy...

A series of new kinds of diester/diurethane tethered azo disperse dyes were synthesized through the reaction between the hydroxyl group in disperse dyes, such as C. I. Disperse Red 1 (1a), C. I. Disperse Red 13 (1b), and C. I. Disperse Blue 106 (1c), and terephthaloyl chloride or p-phenylene dii...

Improving the energy density has been being a challenge for supercapacitors, and the efficient approach is to choose active materials (composites) based on the potential window (chemical stability) and theoretical specific capacitance of both matched electrodes, which usually own unique nano-siz...

Background: Textile dye dermatitis is frequently undiagnosed because clinical awareness is low and because of the absence of good screening allergens in standard patch test series for this type of contact dermatitis.Objectives: To determine the incidence of textile dye allergy in patients with p...

The diagnosis of purpura pigmentosa progressiva in a female patient had to be changed to purpuric contact dermatitis after patch testing with textile dyes. A modified patch test performed in the area in which most of her skin lesions were located revealed a petechial reaction to the azo dye Disp...

IntroductionThe wildebeest is a populous African ungulate, but despite its wide distribution within that continent few reports exist on the structure and endocrine functions of its placenta.

Semiconductors, such as zinc and niobium oxides, are suitable materials for photocatalytic and photo degradation reactions. Mixed zinc-niobium oxides have the same characteristics and could be used for the same purposes. Therefore, ZnO supported on Nb2O5 were synthesized by wet impregnation tech...
