The nonlinear optical responses of Disperse Orange 3 (DO3) dissolved in tetrahydrofuran (THF) with different concentrations were investigated by Z-scan D4σ technique employing 12 ps and 17 ps pulses of Nd:YAG laser at 532 nm and 1064 nm, respectively. The comparison of the experimental results ...

Densitometric high performance thin layer chromatography (HPTLC) quantification method was developed to validate the decolorization/biotransformation of Disperse Orange ERL and dye mixture by lichen Parmelia sp. which release several colored compounds during decolorization process, hence unable ...

An automated method for the determination of cellulase activity has been developed. The enzyme incubation with the cellulose substrate is stopped at alkaline pH, after which the reaction mixture is dialyzed. The concentration of reducing sugar in the dialyzer recipient is determined by means of ...

ObjectiveNeurological impairment is frequently observed in children with congenital heart disease. Impairment in cerebrovascular carbon dioxide reactivity (CO2R) is related with poor neurological outcomes. The study examined CO2R with transcranial Doppler (TCD) and near-infrared spectroscopy (NI...

Doping of nitrogen (N) on carbon materials often requires complicated synthetic steps or specific machinery. In this study, N-doped biochar was successfully synthesized by simply ball milling pristine biochar with ammonium hydroxide. The content and species of N in the resulting N-doped biochars...

Irradiation with red light or near-infrared (NIR) lasers can bio-modulate cellular processes or revitalize injured tissues and therefore, widely been used for therapeutic interventions. Mechanistically, this cellular or biological process, referred as Photobiomodulation (PBM), is achieved by the...

The co-substrate is an important ingredient in the bio-decolourization process to promote the healthy growth and basic activities of bacteria. Most widely used co-substrates in bio-decolourization process are expensive and increase the carbon and nitrogen loading in treated water. The present st...

The chemical structures of six coal samples with different ranks were semi-quantitatively characterized by a series of original infrared structural parameters, and the pyrolysis reactivity of the samples were quantitatively characterized by a comprehensive devolatilization index. A correlation w...

In this study, we report a simple method to synthesize a novel green nanocatalyst using titanium dioxide, graphene and Citrus sinensis peel extract using a low-power CO2 laser fabrication. The relevance of the resulting nanomaterial (Lp-TiO2/G-nCSP) for the photocatalytic degradation of Reactive...

The objective of this study was to investigate the use of nanobiocomposite (CC) containing Chitosan and Cloisite 30B an Organically modified Nanoclay to remove the dyes Reactive blue -21 and Reactive red-141.The effects of adsorbent dose, contact time, and concentration on the adsorption process...

The adsorption potential of hydrotalcite (HT) for reactive blue 21 (RB-21) and reactive red 141 (RR-141) in aqueous solutions has been investigated by batch technique.HT was characterized by X-ray photoelectron spectroscopy (XPS), X-ray diffractometry (XRD), FT-IR spectroscopy (FT-IR), zeta pote...

This work deals mechanical and tribological properties of pure copper, reinforced by various weight percentages of tin, before and after the application of equal channel angular pressing. It is found that the hardness, yield, and ultimate shear strengths are considerably improved through ECAP du...

By using nano TiO2-Y2O3 as catalyst, cataluminescence (CTL) phenomenon of propylene oxide (PO) was studied, and it was found that the sensor has high sensitivity and good selectivity for the detection of propylene oxide. The common volatile organic compounds (VOCs) such as acetone, acetaldehyde ...

Although the advantageous effect of reactive elements on the oxidation resistance of alloys that form protective Cr2O3 scales was discovered 80 years ago, the underlying mechanism has still not been fully explained. One of its aspects, which was investigated in depth in the presented paper, is t...

A novel H2S sorbent based on SnO2 and Y2O3 is developed by a co-precipitation method for steam regenerative removal of H2S from hot syngas at moderate temperatures (400–500 °C). SnO2-Y2O3 sorbent is stable in a reducing atmosphere (i.e. 500 °C, 50% H2) and achieves a 99.9% H2S removal during ...

The influence of alloyed yttrium (0.15–0.3 wt.%) on the fireside corrosion behaviour of Ni-Fe based alloy was investigated at 750 °C. Results show that external scales of Cr2O3 and Al oxide, as well as internal Ti sulphide form during the corrosion regardless of the chemical composition of all...

A new fluorescent probe based on Tellurium-Rhodamine (TR) was designed, synthetized and fully characterized by 1H NMR, 13C NMR, 125Te NMR, HRMS, IR and single crystal X-ray diffraction. A mechanism of Hg2+ detection, based on the oxidation of tellurium by Hg2+ was observed and fully understood. ...

A variety of copper tellurium oxide minerals are known, and many of them exhibit either unusual forms of magnetism, or potentially novel spin liquid behavior. Here, I review a number of the more interesting materials with a focus on their crystalline symmetry and, if known, the nature of their m...

ObjectiveThe aim of present research work was to fabricate and evaluate the Mefenamic acid (MF) loaded Solid lipid nanoparticles (SLNs) using Glyceryl monostearate as lipid and tween 80 as surfactant.
