The genus Fusarium is of concern to agricultural production and food/feed safety because of its ability to cause crop disease and to produce mycotoxins. Understanding the genetic basis for production of mycotoxins and other secondary metabolites (SMs) has the potential to limit crop disease and ...

This study focuses on the possible use of Aspergillus fumigatus to remove acid violet 49 dye (AV49) from aqueous solution. In batch biosorption experiments, the highest biosorption efficiency was achieved at pH 3.0, with biosorbent dosage of 3.0 gL−1 within about 30 min at 40 °C. The Langmuir a...

The oxidation of conjugated polymer on the surface of conjugated polymer/TiO 2 composites is inevitable during the photocatalytic reaction. So it is necessary to research the influence of the degree of oxidation of conjugated polymer on the photocatalytic activity of conjugated polymer/T...

Poly(3-hexylthiophene) (P3HT) and P3HT/cadmium sulfide (CdS) fibers were prepared in order to determine their morphological and structural properties and thermal stability. To our knowledge, this is the first study to investigate electrospun P3HT/CdS fibers. P3HT fibers were manufactured by elec...

Poly(3-hexylthiophene) (P3HT) is utilized as a material to enhance the glucose sensing performance of glucose oxidase (GOx) Langmuir-Blodgett (LB) films. To enhance the extensibility and homogeneity of the P3HT in the LB films, octadecylamine (ODA) is introduced. The characteristics of the mixed...

The exploitation of soluble and efficient deep-red phosphorescent emitters is of paramount importance for solution-processed organic light-emitting diodes (OLEDs) applied in both high-quality RGB displays and high color-rendering-index (CRI) solid-state lighting source. In this work, a new deep-...

Femto-second laser irradiation on P3HT:PCBM solutions have been demonstrated to have a significant impact on the conformational structures and photovoltaic performance of the resultant thin films. The crystallinity and edge-on/face-on conformations of P3HT and the aggregation of PCBM can be mani...

For the purpose of enhancing the field-effect mobility of poly(3-hexylthiophene) (P3HT), multi-walled carbon nanotubes (MWCNTs) were functionalized by attaching covalently P3HT onto the MWCNT surface to yield P3HT-grafted MWCNTs (g-MWCNTs). When a small amount of g-MWCNTs was added to P3HT, the ...

The optical properties of poly(3-hexylthiophene) (P3HT), in pristine form or with added anatase titanium dioxide (TiO2) nanoparticles have been investigated, and the interfacial charge transfer between P3HT and TiO2 have been studied by steady-state luminescence spectroscopy analysis. The photol...

Boron containing ionogels were fabricated through chemical crosslinking of boron allyloxide with polyethylene glycol dimethacrylate in an ionic liquid electrolyte solution to obtain mechanically robust gels. Because of the relatively small concentration of crosslinking agent required to fully so...

Triflic acid and P 4 -t-Bu superbase both catalyze the ring-opening polymerization (ROP) of 2,2,4,4,6,6-hexamethyl-8,8-diphenylcyclotetrasiloxane (I) to yield a mixture of linear copoly(dimethylsiloxane/diphenylsiloxane) (3:1 mole ratio), low molecular weight oligomer and cyclic siloxane...

A high-performance liquid chromatography (HPLC) method has been developed and validated for the simultaneous determination of n-propionyl-p-aminophenol, 3-chloro-4-hydroxyacetanilide, 4'-hydroxyacetophenone, 4-hydroxyacetophenone oxime, 4-acetoxyacetanilide and 4'-chloroacetanilide, the main imp...

The reversed-phase high-performance liquid chromatographic (RP-HPLC) method has been developed and validated for the simultaneous determination of imatinib mesylate and of the impurity product in Glivec ( R) capsules (Novartis, Switzerland). Separations were performed on a X Terra(TM) 15...

We developed novel stability‐indicating HPLC method for simultaneous estimation of 14 impurities in excedrin tablet, a formulation with a combination of acetaminophen, aspirin, and caffeine. In addition, a new impurity that was generated through degradation of aspirin at high temperatures durin...

A simple ratiometric fluorescent sensor for fructose was presented. It consisted of 10-hydroxybenzo[h]quinoline (HBQ) which showed emission at 572nm and 3-pyridylboronic acid (PDBA) whose complex with HBQ gave emission at 500nm. The reaction of fructose with PDBA inhibited the complexation of HB...

Boronate affinity chromatography (BAC) is a unique means for the selective separation and enrichment of 1,2 and 1,3 cis-diol-containing compounds. However, conventional boronate affinity materials require a basic binding pH (usually≥8.5), which gives rise to not only inconvenience in operation ...

5,5′-Dibromo-2,2′-dipyridylacetylene was prepared from 2,5-dibromopyridine and (trimethylsilyl)acetylene via the new one-pot synthesis approach using a regioselective palladium-catalyzed coupling reaction with a 60% yield. Several protocols of lithium–halogen exchange were then attempted to s...

Monofluorinated polycyclic aromatic hydrocarbons (F-PAHs) are useful reference compounds for a broad spectrum of PAH studies. The pyrene metabolite 1-hydroxypyrene is often used as a biomarker of PAH exposure. Two species, isopod (Porcellio scaber) and flatfish (Platichthys flesus), that produce...

As a sequel to an earlier paper, we have studied the behaviour of 1-fluoropyrene and pyrene in lamp-excited Shpol'skii spectrofluorimetry at 11K in two different matrices, n-octane and n-hexane, using two different solidification processes. Particular attention is paid to the suitability of 1-fl...
