Fungal keratitis (FK) is a corneal infection caused by different fungal species. It treated the topical application of natamycin (NAT). Nevertheless, this approach faces many limitations like toxic effects, frequent dosing, resistance, and patient discomfort. The present research reports development trimethyl chitosan (TMC) coated mucoadhesive cationic niosomes modified thin-film hydration meth...

Anion exchange membranes (AEM) are key components in anion membrane water electrolysers. Recently developed materials less susceptible to the alkaline degradation of polymer backbone and quaternary ammonium groups. A remaining challenge is mechanical stability contact with hot dimensional when temperature feed solution changes. One reinforce a porous support. Since support like PEEK or PTFE hav...

1. In an attempt to assess the structural requirements for the muscarinic receptor selectivity of hexahydro-diphenidol (hexahydro-difenidol) and hexahydro-sila-diphenidol (hexahydro-sila-difenidol), a series of structurally related C/Si pairs were investigated, along with atropine, pirenzepine and methoctramine, for their binding affinities in NB-OK 1 cells as well as in rat heart and pancreas....

The need to take into account the life cycle of ionic liquids (ILs), from sourcing raw materials involved in their synthesis disposal and degradation, has become paramount design new IL-type molecular structures. In case 1-alkyl-3-methylimidazolium salts, one prominent IL families, there is an increasing demand for synthetic methods involving (i) substitution petro-based alkyl derivatives by re...

Reverse electrodialysis (RED) membrane is an emerging renewable energy which harvest electricity from mixing two streams on different salinities. In real practice still not clearly defined for the effectiveness of salinity gradient power (SGP)-RED due to limitation artificial saline water. Generally, South Kalimantan Indonesia rich by wetland and coastal area. Due that water potential as source...

The synthesis and characterization of EtOSHPh2PNCH2CHjh(HNCH2CH21N (ethoxy·N,N'·bis(di. phenylphosphinolazasilatrane, the title compound 3b) is reporud. ts reactions with sulfur and Mel proceed easily via quaternization at the phosphorus sites to give the bis(phosphonium) salt and the bis(phosphlne) sulfide, respectively. Synthesis and characterization of the coordination compounds (3b)Ni(COh, ...

Two new intercalates of tris[4-(pyridin-4-yl)phenyl]amine (TPPA) with zirconium hydrogen phosphate and zirconium 4-sulfophenylphosphonate having formulae Zr(HPO4)2·0.21(C33H24N4)·2.5H2O and Zr(HO3SC6H4PO3)(1.3)(C6H5PO3)(0.7)·0.35(C33H24N4)·2.5H2O were prepared and characterized by thermogravimetry, IR spectroscopy, and powder X-ray diffraction. The TPPA molecule has been selected as a model tri...

Polysulfobutylbetaine (SBB) (co)polymers, zwitterionic species bearing ammonium and sulfonate groups separated by a butyl spacer in every repeat unit, were prepared through three different synthetic routes and their aqueous solution behaviour was studied. Postpolymerization quaternization of poly[2-(dimethylamino)ethyl methacrylate] with 1,4-butanesultone resulted in incomplete modification due...

Chitosan (CS) has already gained considerable attentions as vehicles for mucosal immunizations due to its excellent biocompatibility, biodegradability and non-toxicity. However, poor aqueous solubility and loss of penetration-enhancing above pH 6 are major drawbacks for its use as oral vaccine carrier. The study aims to investigate the potential utility of O-methylated free trimethylated chitos...
