Full concentration gradient lithium-rich layered oxides are catching lots of interest as the next generation cathode for lithium-ion batteries due to their high discharge voltage, reduced voltage decay and enhanced rate performance, whereas lithium residues on its surface impairs structure stability long-term cycle performance. Herein, a facile multifunctional modification method is implemented...

Determination of the kinetics of water-soluble degradation products inside poly(lactide-co-glycolide) (PLGA) delivery systems during polymer degradation is important to evaluate the polymer microclimate conditions, particularly microclimate pH changes for optimization of encapsulated drug stability. A pre-derivatization high-performance liquid chromatography (HPLC) method was developed for sepa...

TiO₂ sol was produced by the sol-gel method through the hydrolysis and the aging of tetrabutyl titanate and the TiO₂ film was obtained by dipping and uniform lifting of the acid-treated and ultrasound-treated clean glass slides into the TiO₂ sol followed by aging, drying, and calcination. The effect of the hydrolysis control agents to the formed sol was researched and the crystalline state, the...

Wood-TiO2 (titania) composites were prepared by a sol-gel process, in which wood was impregnated with the precursor solutions prepared from tetrabutyl titanate (TBT), followed by a curing step. The surface morphology and moisture absorption behavior of the wood composites, as well as their thermal and mechanical performances, were examined. Environmental scanning electron microscopy (ESEM) anal...

An isocratic, selective, and accurate Ion pair reversed phase liquid chromatographic method of analysis of Furosemide and Zonisamide both as a bulk drug and formulations was developed and validated. An ODS chromatographic column (250mmx4.6mm, 5μm) was used for the separation. The mobile phase consisted of a mixture of methanol and Tetrabutyl ammonium hydrogen sulphate (TBHS) 0.035 molar aqueous...

A simple, isocratic and robust RP-HPLC method for the analysis of azithromycin was developed, validated and applied for the analysis of bulk samples, tablets and suspensions. The optimum chromatographic conditions for separation were established as a mobile phase comprised of acetonitrile-0.1 M KH₂PO₄ pH 6.5-0.1 M tetrabutyl ammonium hydroxide pH 6.5-water (25:15:1:59 v/v/v/v) delivered at a fl...

A series of composites consisting of anatase TiO2 nanocrystals and three-dimensional (3D) graphene aerogel (TiO2-GA) were self-assembled directly from tetrabutyl titanate and graphene oxides via a one-pot hydrothermal process. TiO2 was found to uniformly distribute inside the 3D network of GA in the resulting composites with large surface areas (SBET > 125 m(2) g(-1)) and high pore volumes (Vp ...

EXPERIMENTAL SECTION Materials and reagents Tetrabutyl titanate (TBOT), sodium dodecyl sulfate (SDS), sodium dodecyl benzene sulfonate (SDBS) and phosphoric acid (H3PO4) were from Nanjing Chemical Reagent Co., Ltd. (Nanjing, China). Human IgG (HIgG) (Ag), rabbit anti-human IgG (Ab1), and goat anti-human IgG (Ab2) were purchased from Beijing Biosynthesis Biotechnology Co., Ltd. (Beijing, China)....

In the present work, the seedless, highly aligned and vertical ZnO nanorods in 3 dimensions (3D) were grown on the nickel foam substrate. The seedless grown ZnO nanorods were characterised by field emission scanning electron microscopy (FESEM), high resolution transmission electron microscopy (HRTEM), and X-ray diffraction (XRD) techniques. The characterised seedless ZnO nanorods in 3D on nicke...
