Mannan is one of the major constituent groups of hemicellulose, which is a renewable resource from higher plants. β-Mannanases are enzymes capable of degrading lignocellulosic biomass. Here, an endo-β-mannanase from Rhizopus microsporus (RmMan134A) was cloned and expressed. The recombinant RmM...

Dyeing of solid wood using scCO2 as transport medium does not afford satisfying results as exemplarily demonstrated for disperse blue 134 and different wood species. Surprisingly, the bark of cork oak featuring closed porous architecture could be easily dyed with DB 134 which was hypothesized to...

RM was used for the upgrading of vacuum residue (VR) by partial oxidation (POX). The function of diverse metal oxides in RM during VR upgrading was clarified and the utilization of used RM was developed. The results show that POX of VR with RM600 (calcined RM at 600 °C) decreases the cracking t...

In this study, dispersive liquid-liquid microextraction coupled with ultra-high-performance liquid chromatography–tandem mass spectrometry was developed for the analysis of five representative organophosphate esters (OPEs) in wine samples. Under optimized conditions, the proposed method resulte...

To compare the oil displacement mechanisms and performances of continuous phase flooding agent (traditional polymer solution) and dispersed phase flooding agent (particle-type polymer SMG dispersion), the particle phase separation of SMG dispersion migrating in pores was simulated by using the m...

This study investigates the partition of molybdenum in presence of hydrochloric acid with Cyphos IL 104 diluted in toluene and recovery of molybdenum from spent hydrodesulphurization catalyst. Effect of various parameters has been estimated. Recyclability and loading capacity have been assessed....

Hybrid core-shell catalysts were synthesized by transition metal (Fe, V and Cu) oxides dispersed on Ti doped mesoporous Ti-MCM-41 (noted as TiM) and their crystalline structures, morphologies, metal oxidation states and optical properties were studied with a variety of characterization technique...

New experimental intensity results obtained by band integration from the PNNL (Pacific Northwest National Laboratory) spectral library are reported for 26 CH vibrations of methane, acetylene, ethylene, ethane, allene, propyne and cyclopropane. The PNNL intensity values range from 3.1 to 185.4 km...

This work reports preparation and characterization of ZnO nanoparticles prepared by low temperature hydrothermal methods and their application for anionic dye (Congo red) and cationic dye (Brilliant green) removal from aqueous medium. The adsorption capacity of ZnO nanoparticles for Congo red dy...

Polyester/cotton fabric which had been dyed with disperse and reactive dyes can be washed-off using two, novel processes that employ nylon beads. The bead wash-off processes furnished dyeings that were of similar colour strength and colour to those which had been reduction cleared in the case of...

Both 2% and 5% omf dyeings of polycotton fabric which had been produced using commercial grade disperse dyes and reactive dyes can be washed-off using two, novel processes that utilise polyamide beads. The bead wash-off processes provided dyeings that were of similar colour, depth of shade and f...

Z-scan technology, numerical simulation and degenerated pump-probe experiment under different polarization configurations, were performed to study the ultrafast nonlinear optical properties of a dispersed red one (DR1) derivative (DR1-T, dissolved in THF solution) based on triphenylamine. The ul...

The development of methodologies to detect and quantify azo dyes in treated water is required because some of these dyes exhibit genotoxic activity, even at low concentrations. Here, the construction and characterization of an impedimetric immunosensor for determination of the textile azo dye Di...

Ceramic coatings have been widely used in industrial fields. K2Ti6O13 fibers could be a potential coating material for low thermal conductivity, high mechanical strength and infrared reflectivity. The precursor fibers, using potassium acetate (CH3COOK) and tetrabutyl titanate (TBOT) as potassium...

Knowledge of key species sensitivity for oil spill response (OSR) options is needed to support decision-making and mitigate impact on sensitive life stages of keystone species. Here, Northern shrimp (Pandalus borealis) larvae were exposed for 24 h to a gradient (H-High, M-Medium: 10 times diluti...

This work describes the efficiency of photoelectrocatalysis based on Ti/TiO2 nanotubes in the degradation of the azo dyes Disperse Red 1, Disperse Red 13 and Disperse Orange 1 and to remove their toxic properties, as an alternative method for the treatment of effluents and water. For this purpos...

Multifunctional polymeric microspheres were prepared using hyper-cross-linking chemistry combined with surface-initiated atom transfer radical polymerization. The synthesized microspheres exhibited good water dispersibility, a high surface area, and pH/thermo dual-responsiveness. Fluoroquinolone...

TiO2/WO3 nanocomposites (NCs) were successfully prepared by ultrasonic-assisted sol-gel method and acid functionalized (sulfated) by using chlorosulfonic acid. Various physicochemical properties of as prepared NCs were studied by using X-ray diffraction spectroscopy, Fourier transform infrared s...

The present work assessed the ecotoxicity of the commercially available form of the azo dye Disperse Red 1 (DR1) and the main degradation products generated during photo-Fenton degradation. The acute toxicity tests with the microcrustacean Daphnia similis showed that toxicity increased after 10 ...

Tredomen Quarry, near Brecon, South Wales, is regarded as a Lower Old Red Sandstone terrestrial lagerstätten and has yielded a palaeobotanical assemblage that illustrates the diversity and possible affinities of early vegetation across the Anglo–Welsh Basin during the lower Lochkovian (Early De...
