The photoinduced dynamics of pyrrole is revisited employing the independent trajectory surface hopping methodology based on extended multi-state second order perturbation theory (XMS-CASPT2). Excitation at 200 nm into a high density of states region gives rise to ultrafast deactivation via inter...

The most red-shifted hemithioindigo photoswitches have been identified through systematic introduction of aryl units to a parent pyrrole hemithioindigo photoswitch. Increasing the size of the 5′-aryl substituent is ineffective at producing further redshifted chromophores. A second generation of...

In this work we present the direct electrodeposition of poly(pyrrole)/Prussian blue composite nanostructures under ultrasonic radiation. Different characterization techniques were employed such as scanning electron microscopy, electrochemical impedance spectroscopy and voltammetric experiments. ...

We demonstrate the spatial separation of pyrrole and pyrrole(H2O) clusters from the other atomic and molecular species in a supersonically-expanded beam of pyrrole and traces of water seeded in high-pressure helium gas. The experimental results are quantitatively supported by simulations. The ob...

A magnetic nanocomposite adsorbent based on cress seed mucilage (CSM) was synthesized for removing methylene blue (MB) cationic dye from aqueous solutions. These adsorbent nanoparticles were prepared by in situ formation of magnetic iron oxide nanoparticles (MIONs) coupled with CSM mucilage and ...

In this paper, we reported the synthesis of a new family of thermal stable Mn-doped DyInO3 blue pigment materials. All of the samples were synthesized by a conventional solid state method. Powder x-ray diffraction refinement results showed that the structures of the as-prepared materials were he...

BackgroundBasal cell carcinoma (BCC) is the most frequent of all skin cancers in the white population. The typical dermoscopic features of pigmented BCCs have been well known. In the literature a new dermoscopic pattern of BCC has been reported as “blue-white variant”.

The influence of build orientation, layer thickness, strain rate and size effect on the Young’s modulus, ultimate tensile strength and fracture strains in vat photopolymerization based additively manufactured specimens is investigated. Mechanical testing and subsequent scanning electron microsc...

Novel 3-amino-1-hetarylfluorene derivatives have medicinal uses and challenging transformation in organic synthesis have been synthesized via decyanation process. Surprisingly, the alkylated compounds derived from 3-Amino-1-hetarylfluorenes were obtained via further nucleophilic substitution to ...

Cross-linked beads of activated oil palm ash zeolite/chitosan (Z-AC/C) composite were prepared through the hydrothermal treatment of NaOH activated oil palm ash followed by beading with chitosan. The effects of initial dye concentration (50–400 mg/L), temperature (30 °C–50 °C) and pH (3–13)...

Cellulose membranes were fabricated via phase inversion using 1-ethyl-3-methylimidazolium acetate as solvent and acetone as volatile cosolvent. 1,2,3,4-butanetetracarboxylic acid was used to partially crosslink the hydroxyl groups of cellulose, thereby changing mechanical properties of the membr...

This study investigated the effect of a water-assisted ultraviolet system (WUV; samples were treated by UV while being immersed in agitated water) on the inactivation of Salmonella on baby spinach, iceberg lettuce, blueberry, grape tomato, and baby-cut carrot. The Salmonella inactivation effect ...

Owing to low bearing capacity and efficiency, traditional filters or adsorbents for removal of contaminants like crystal violet (CV) dye required frequent replacement. Besides, the combination of three-dimensional (3D) printing and bionics could break the constraints of traditional configuration...

In this study, the effect of abiotic stress on the acidophilic eukaryotic microalga, Coccomyxa onubensis, was analyzed for the production of lutein and PUFAs (polyunsaturated fatty acids). It grows autotrophically at a pH of 2.5. It showed a growth rate of 0.30 d−1, and produced approximately 12...

Persistent UV quenching substances (UVQS) in landfill leachate can affect the effectiveness of UV disinfection in domestic wastewater treatment systems when leachate is being co-treated. As a result, effective onsite leachate pre-treatment will have to be implemented to reduce the UV quenching c...

This study investigated individual and combined effects of organic acids, bacteriophages, and ultraviolet light interventions on Salmonella populations in ground beef. Beef trim was inoculated with four Salmonella strains to result in a contamination level of 3.5 log CFU/g after grinding. Lactic...

2,3-epoxyalcohols are shown to undergo stereoselective reactions in the presence of tin tetrachloride. The resulting diols when treated with acid are converted into polycyclic aromatic hydrocarbons or polycyclic ketones.

Metabotropic glutamate receptors are thought to play a role in the development and maintenance of spinal hyperexcitability resulting in hyperalgesia and pain. In this study we have used in situ hybridization to investigate the distribution of metabotropic glutamate receptors mGluR1–7 messenger ...

One of the important worldwide environmental problems is the improper discharge of colored effluents to aqueous ecosystems which causes acute toxic effects on aquatic flora and fauna. The present study concentrates on efficiency and potentiality of a bacterium isolated from a textile effluent to...

The effect of orange fiber addition on yogurt viscoelastic properties was studied, the following factors were evaluated: (i) fiber doses (0, 0.2, 0.4, 0.6, 0.8 and 1 g/100 ml) (ii) fiber particle size (0.417–0.7 and 0.701–0.991 mm) (iii) fiber addition prior or after pasteurization. (i) In yog...
