A new type of Ag<sub>3</sub>PO<sub>4</sub>/AgBr/hydroxyapatite photocatalyst was prepared from oyster shells, which showed high efficiency in the degradation organic dyes.
Two novel, designated strains 29W222T and 2943T, were isolated from the marine sediment Aoshan Bay, Jimo, PR China. Growth was observed at pH 6.0-8.5 (optimum, 7.5) for strain 29W222T, 5.5-8.5 (pH 7.0) 2943T. Both displayed growth in 0.5-6 % NaCl with an optimum 1 29W222T; 0.5 grew optimally 33 °C. The results of phylogenetic analyses based on 16S rRNA gene sequences indicated that 2943T represented members genus Fulvivirga most closely related to kasyanovii KMM 6220T (97.9 sequence...
Thermothickening polymers are a novel type of material developed for enhanced oil recovery applications in high-temperature and high-salinity reservoirs. However, the existing synthesis process thermoviscosifying is complex high cost, both which limit wide application polymers. In this study, thermothickening water-soluble polymer (PHAD) with low concentration was synthesized by "graft from" method, acrylamide diacetone as grafted monomers hydroxypropyl methyl cellulose backbone chain. The...
A novel ternary Ag3PO4/g-C3N4/hydroxyapatite photocatalyst was prepared, and its morphology, composition structure were characterized by X-ray diffraction, photoelectron spectroscopy, scanning electron microscopy, high-resolution transmission spin resonance, etc. The results show that g-C3N4 is evenly dispersed in the interior of hydroxyapatite, forming a homogeneous composite, significantly improves band gap material as whole. has good transfer ability an appropriate energy structure, which...
A Gram-stain-positive, rod-shaped, whitesmoke-coloured and aerobic bacterium, designated strain Co35T, was isolated from the intestine of Collichthys lucidus collected Jiangmen Guangdong Chinese White Dolphin Provincial Nature Reserve. Strain Co35T able to grow at 15-35 °C (optimal 28 °C), pH 7.0-8.5 8.0) with 0-9 % (w/v) NaCl 0.5-1 %). Phylogenetic analysis based on 16S rRNA gene sequences revealed that a member genus Aeromicrobium within family Nocardioidaceae. The genomic DNA G+C content...
As a "green" displacing agent, nanocellulose is enriched, nontoxic, biodegradable, and environmentally friendly; therefore, the development potential application of in oilfield chemistry have attracted widespread attention recent years. In this study, thermothickening copolymer synthesized our laboratory called hydroxypropyl methyl cellulose-based graft (PHAD) was chosen to mix with Halocynthia roretzi Drasche-based cellulose nanocrystals (TCNCs), anionic surfactant sodium dodecyl sulfate...
Cellulose-insoluble silicate (talcum powder) hybrid fibers with 10%, 20%, 30% silica contents were prepared by wet spinning. The flammabilities and combustion processes evaluated the limiting oxygen index (LOI) cone calorimetry. LOI results suggested that flame retandant value of 22, 25 27, as compared to 20 pure cellulose fibers. Cone calorimetry showed rate heat release total decreased. Hybrid 20% SiO 2 loading is best retardant sample. SEM studies residues after indicated produced tight...
We have investigated the effect of zirconium oxide on thermal degradation and flame retardancy viscose fibers. ZrO 2 /cellulose fiber was prepared by wet spinning. Combustion behaviour flammability were assessed using limiting oxygen index (LOI) thermogravimetric analysis from ambient temperature to 800°C cone calorimetry. LOI results showed that increased 20% 26%, which particles had a positive cellulose flame-retardancy. Results (TG) indicated fibers produced greater quantities residues...
