We examined the sub-lethal effect of Macondo oil from the Deepwater Horizon oil spill on predator-prey interactions using blue crabs (Callinectes sapidus) and periwinkle snails (Littoraria irrorata). A 2 × 2 factorial mesocosm design determined the effect of oil (no oil vs. oil) and blue crabs ...

N-doped porous carbon material has exhibited unique adsorption properties. However, it remains as a challenge to recycle the carbon adsorbent. In this work, a monolithic N-doped carbon material was manufactured via the direct ink writing, a conventional 3D printing technology. Melamine was used ...

Direct numerical simulation (DNS) has been performed for a spatially developing 90° bend pipe flow to investigate the unsteady flow motions downstream of the bend. A recycling method is implemented to generate a fully-developed turbulent inflow condition. The Reynolds number of the pipe flow is...

In the present study, efficient adsorptive removal of fluoride and Direct Blue 53 (DB-53) dye solution on perovskite lanthanum aluminate (PLA) has been investigated. To characterize the prepared PLA with analytical techniques like FTIR, SEM, EDS, PXRD, PHZPC and BET. The influence of adsorbent d...

Azo dyes are widely used in the textile industry despite being poorly biodegradable and highly toxic. Hence, azo dyes need to be removed from effluent prior to environmental discharge. Microbial communities are efficient for the degradation and mineralization of azo dyes. However, little is know...

An Upflow Anaerobic Sludge Blanket Reactor/Continuous Stirred Tank Reactor was used sequentially to decolorize and mineralize C.I. Direct Black 38 azo dye (3200 mg/L) in a synthetic wastewater containing glucose as co-substrate. At the steady state conditions color was effectively removed under ...

Pigmentation of Vat Blue RS by ball milling in the presence of organic solvents or water was carried out and the effects of ball milling time, characteristics of solvent used and two-step ball milling on the transformation of crystal phase and the resulting pigment properties were studied. Exper...

An indirect competitive enzyme-linked immunosorbent assay capable of detecting the reactive triazine dye C.I. Reactive Blue 2 at concentrations down to 300 pM was developed, and representing a 3000-fold higher sensitivity over direct spectrophotometric analysis. An investigation of the cross-rea...

The molecular and crystal structures of two yellow, azo disperse dyes having the same pyridine-1-ethyl-3-cyano-4-methyl-2,6-dione backbone, namely C.I. Disperse Yellow 119 and C.I. Disperse Yellow 211 were studied. Both dyes crystallize in the hydrazone form both at 291 and 120 K, with hydrogen ...

The mechanism of interaction between C.I. Direct Yellow 9 and human serum albumin was studied using spectroscopic methods including fluorescence spectra, UV–vis, Fourier transform infrared (FT-IR) and circular dichroism (CD). The quenching mechanism was investigated in terms of the association ...

A comprehensive study of the effects of C.I. Food Red 9 on the conformation and activity of pepsin was performed using multi-spectral methods and molecular docking technique. Fluorescence and circular dichroism spectral analyzes showed that C.I. Food Red 9 binding induced the changes of secondar...

This work tests the viability of applying ozone (O3) and O3 combined with ultraviolet (UV) to degrade the content of synthetic wastewater containing Direct Blue 86 (DB-86) dye. The tested parameters, which included pH, initial concentration of DB-86 dye and time of reaction, were tested in a bat...

Crystals of C.I. Disperse Blue 79, a commercial aminoazobenzene dye, were grown from an ethyl acetate solution and the crystal structure was determined by single crystal X-ray diffraction analysis. The dye molecule crystallizes in the triclinic space group P-1 with the unit cell dimensions: a=11...

The aim of this study was to assess the retention and selectivity of a cocktail of 10 substrates of uridine diphosphate glucuronosyltransferase enzymes (UGTs) and their respective glucuronides using four chromatographic approaches. For this purpose, seven different stationary phases were employe...

The spectroscopic characteristics of the solid charge-transfer molecular complexes (CT) formed in the reaction of the electron donor 4-(aminomethyl) piperidine (4AMP) with the σ-acceptor iodine and the π-acceptors 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ), 2,4,4,6-tetrabromo-2,5-cyclohex...

Diabetic nephropathy (DN) is one of the most common causes of end-stage renal disease (ESRD). Oxidative stress and inflammation have been documented to play important roles in the pathogenesis of DN. Daphnetin, a natural coumarin compound, possesses antioxidant and anti-inflammatory activities. ...

The bacterial pneumonia caused by methicillin-resistant Staphylococcus aureus (MRSA) is a potentially fatal disease, featured with extensive infection, inflammation, and airway dysfunction. With the increasing emerging of drug-resistant strains, new therapeutic strategies beyond canonical antibi...

Daphnetin, one of the major bioactive components isolated from Daphne odora, has been reported to have anti-inflammatory and anti-oxidative effects. Inflammation and oxidative stress have been known to play critical roles in cisplatin-induced nephrotoxicity. The purpose of this study was to inve...

TiO2 nanoparticles with unique crystalline-core/disordered-shell structures were synthesized in a one step process by employing 4-methoxycalix[7]arene nanoreactors.
