Isothermal vapour–liquid equilibrium data (VLE) were measured for propionic acid+caproic acid, isobutyric acid+caproic acid, valeric acid+caproic acid, and caproic acid+enanthoic acid at several temperatures. A refined glass recirculating still with a packed equilibrium chamber and a vacuum-ins...
In this study, the ability to modulate rheological and degradation properties of temperature-responsive gelling systems composed of aqueous blends of poly(ε-caprolactone-co-lactide)-b-poly(ethylene glycol)-b-poly(ε-caprolactone-co-lactide) (PCLA–PEG–PCLA) triblock copolymers (i.e. uncapped) ...
Solid solutions of hexanoyl chitosan/poly(vinyl chloride) (PVC) blends comprising sodium iodide (NaI) were studied. Differential scanning calorimetry results reveal that (i) hexanoyl chitosan and PVC are immiscible and (ii) preferential interaction of NaI with hexanoyl chitosan than PVC. X-ray d...
We developed hexanoyl chloride–modified chitosan (Nac-6) stabilized iron oxide nanoparticles (Nac-6-IOPs) as magnetic nanoparticles for viral gene (Ad/LacZ) delivery via magnetofection. This vector, Nac-6-IOPs/Ad/LacZ, binds to K562 cells in the presence of external magnetic fields and results ...
A novel dispersive liquid–liquid microextraction (DLLME) method followed by HPLC analysis, termed sequential DLLME, was developed for the preconcentration and determination of aryloxyphenoxy‐propionate herbicides (i.e. haloxyfop‐R‐methyl, cyhalofop‐butyl, fenoxaprop‐P‐ethyl, and fluazifop...
This project demonstrates a novel amperometric method to measure the concentration of nabam through a process of potential assisted surface oxide on the copper based electrode. Based on the strong cuprous ion chelating capability of nabam, the cuprous oxide layer is dissolved away from the elect...
Salbutamol laurate is a novel salt form of the well-known bronchodilator salbutamol (albuterol). Its polymorphism and inclusion in (2-hydroxypropyl)-β-cyclodextrinwere investigated by thermogravimetry, differential scanning calorimetry, infrared and powder X-ray diffraction techniques. Two poly...
Accurate prediction of the interactions between evaporating liquid droplets and solids are critical for many industrially important processes. A model based on coupled Level Set-Volume of Fluid approach was developed to simulate the interaction of evaporating liquid droplets with hot solid surfa...
The combination of a CFD (Computational Fluid Dynamic) code and a detailed chemical kinetic mechanism is a very powerful tool for its use in the development of new Internal Combustion Engines (ICE). However, the large computation demands of this combination have encouraged researchers to develop...
The same configured calorimeters were built in Hefei (99.8 kPa) and Lhasa (66.5 kPa), respectively. Four sizes of round pans with diameters of 10, 15, 20, and 25 cm were adopted to study the effect of high altitude on the burning behavior of liquid pool fires. Analysis on the burning rate obtain...
We evaluated the potential of a lipolytic extract from Penicillium corylophilum for use in biocatalysis. Lipolytic activity was stable when the extract was incubated in the presence of hydrophobic solvents. In fact, when the extract was incubated in n-heptane with an initial water activity of 0....
Purpose This study was designed to assess the safety and effectiveness of ethanolamine oleate (EO) sclerotherapy combined with transarterial embolization using a liquid adhesive agent (n-butyl cyanoacrylate, NBCA) for treatment of extracranial arteriovenous malformations (AVMs). Methods Twenty...
Lipase from Candida rugosa was immobilized by entrapment on poly(N-vinyl-2-pyrrolidone-co-2-hydroxyethyl methacrylate) [poly(VP-co-HEMA)] hydrogel, cross-linked with ethylene glycol dimethacrylate (EDMA). The immobilized enzyme was used in the esterification of oleic acid with butanol in hexane....
. A screening procedure was established to identify Corynebacterium glutamicum transposon mutants with an altered L-glutamate excretion behaviour. By this microtiter plate-based approach seven non- or less excreting C. glutamicum strains and two hyper-excreters were found. The subsequently carri...
Due to the important physiological functions of GABA, various methods used to produce it. Biotransformation by microorganism cells is a more promising method than others. Among the GABA-producing lactic acid bacteria, one strain with high producing capacity was isolated from Chinese naturally pi...
A highly sensitive and selective glutamate microbiosensor based on polypyrrole (PPy), multiwalled carbon nanotubes (MWCNT) and glutamate oxidase (GluOx) deposited on the transducer platinum electrode (Pt) is described. The sensor consists of a permselective membrane of polypyrrole for the reject...
Single crystals of anhydrous ammonium acetylenedicarboxylate ((NH 4 ) 2 (C 4 O 4 ), 1) were isolated from a precipitate crystallizing from an aqueous ammonia solution containing acetylenedicarboxylic acid. The crystal structure of 1 (C2/m, Z=2) consists of ordered...
Z-scan measurements of single walled carbon nanotube (SWCNT) doped with acetylenedicarboxylic acid (ADC) polymer are performed using a CW diode laser at 635nm wavelength with 17mW power. The nonlinear absorption coefficient (β), nonlinear refractive index (n2), the real and imaginary parts of t...
The crystalline compounds quinolin-8-ol (1) and its two salts 2, and 3 have been prepared and structurally characterized. Compound 1 crystallizes in the triclinic, space group P-1, with a = 6.5775(5) Å, b = 7.8285(6) Å, c = 14.4617(13) Å, α = 96.099(2), β = 92.4700(10)°, γ = 106.171(3), V = ...
A cationic dendrimer-type tetrameric surfactant (C 8 qbG0) with four octyl chains and four ammonium groups was synthesized by the reaction of poly(amidoamine) dendrimers with generation of zero and glycidyldimethyloctylammonium bromide. The physicochemical properties of C 8 qbG0 ...
