Aluminophosphate-5 (AlPO4-5) nano-pore zeolite was synthesized. The effect of alteration in precursor gel preparation on the morphology of zeolite was studied. The effect of variety of synthesis conditions on the purity, crystal and pore size, and crystallinity of AlPO4-5 zeolite been studied. A hydrothermal synthesis has been used to produce nano-pore Aluminophosphate-5 c...

In this paper, carbon nanotubes (CNTs) were added into chitosan (CS) hydrogels in the form of chitosan modified CNTs (CS-CNTs) composites to prepare carbon nanotubes hydrogels (CNTs-GEL). The products, named CS-MWCNTs, were characterized by scanning electron microscope (SEM) and Fourier transform infrared (FTIR) spectroscopy. Swelling properties and effect of pH on controlled release performanc...

Knowledge of the transitions occurring during formation ion-conducting polymer films and membranes is crucial to optimize material performances. The use non-destructive scattering techniques that offer high spatio-temporal resolution essential investigating such structural transitions, especially when combined with complementary probing at different time spatial scales. Here, a simultaneous mul...

The Centre for the AIDS Program of Research in South Africa (CAPRISA) 004 trial assessed the effectiveness and safety of a 1% vaginal gel formulation of tenofovir, a nucleotide reverse transcriptase inhibitor, for the prevention of HIV acquisition in women. A double-blind, randomized controlled trial was conducted comparing tenofovir gel (n = 445 women) with placebo gel (n = 444 women) in sexua...

The transformation between a gel and a fluid phase in dipalmitoyl-phosphatidylcholine (DPPC) bilayers has been simulated using a coarse grained (CG) model by cooling bilayer patches composed of up to 8000 lipids. The critical step in the transformation process is the nucleation of a gel cluster consisting of 20-80 lipids, spanning both monolayers. After the formation of the critical cluster, a ...

Self-sorting processes in the assembly of gel-phase materials from mixtures of different molecular-scale building blocks can lead to the spontaneous orthogonal assembly of two different nanoscale gel-phase networks at the same time.

background: different treatment and protective approaches for radiation-induced oral mucositis have been practiced and have varieties of success. of which, radioprotective agents, synthetic or natural, have been of great interest for researchers. this study aims to evaluate the effect of curcuma longa topical gel as a herbal production on mucositis induced by radiation therapy of head and neck ...

A computer simulation model is used to study the kinetics of gelation of a low concentration of bifunctional (C~) and tetrafunctional (C~) monomers on a simple cubic lattice. The mobilities of the monomers and the micragel panicles are considered. Monomers react with their neighbors with a certain probability after hopping with a fixed number of steps. Growth of the concentration of saturated b...

Water-soluble AstaSana astaxanthin (AST) was loaded into 75/25 blend films made of polysaccharides (carboxymethyl cellulose (CMC), gum Arabic (GAR), starch sodium octenyl succinate (OSA), water-soluble soy (WSSP)) and gelatin (GEL) at levels 0.25, 0.5, 1%, respectively. Due to the presence granules in AST formulation, supplemented exhibited increased surface roughness as compared AST-free films...

A procedure for the isolation of target PCR bands from multiplex PCR products using the E-Gel iBase Power System, an E-Gel Safe Imager Real-Time Transilluminator, and E-Gel CloneWell 0.8% SYBR Safe agarose cassettes is presented. The collected isolates are suitable for direct use in sequencing reactions without need of further purification. Reductions in time spent per sample and cost per seque...
