The degree of hydrophobicity in cationic polymers plays an important but often underappreciated role in the safety and efficacy of gene delivery processes. In order to further elucidate structure-activity relationships of biodegradable cationic poly(carbonate) gene carriers, we synthesized a ser...

A new ATRP initiator, viz, 2-oxo-1,3-dioxolan-4-yl-(methyl-2-bromo-2-methylpropanoate) (ODMBMP) was synthesized by the reaction of commercially available glycerol carbonate with 2-bromoisobutyrylbromide and was used to carry out ATRP reactions of methyl methacrylate (MMA) in the presence of copp...

A heterogeneous catalyst, TiO2 supported on Al2O3 was used for the synthesis methyl propyl carbonate (MPC) by the transesterification of dimethyl carbonate (DMC) and propanol. The morphological and chemical states of titanium species in TiO2/Al2O3 were characterized by means of X-ray diffraction...

Destruction of 4-phenolsulfonic acid (4-PSA) in water was carried out using anodic contact glow discharge electrolysis. Accompanying the decay of 4-PSA, the amount of total organic carbon (TOC) in water correspondingly decreased, while the sulfonate group of 4-PSA was released as sulfate ion. Ox...

A new method has been developed for the mild and efficient Rh(III)-catalyzed direct C–H cyanation of a diverse range of N-methoxybenzamides using N-cyano-N-phenyl-p-toluenesulfonamide as an environmentally friendly and efficient cyanating reagent. This new reaction proceeded with good regiosele...

In this work, an interesting oxygen transfer reaction in the gas phase dissociation of N-phenyl p-toluenesulfonamides has been explored by combination of the ESI–MS techniques and theoretical calculations. The protonated molecules underwent dissociation reactions, upon collisional activation, t...

An efficient, mild, inexpensive and eco-friendly protocol for the synthesis of p-toluenesulfonamide derivatives by aza-Michael addition reaction of p-toluenesulfonamide to fumaric esters using potassium carbonate under ultrasound irradiation was developed. This method is simple, convenient and t...

Deep eutectic solvents (DESs) are receiving increasing attention as ionic liquid analogues because of their environmentally friendly and very low-price characteristics. In this study, metal-based deep eutectic solvents (MDESs) were synthesized by combining cobalt chloride (CoCl2), a hydrogen bon...

We investigate the growth of the hybrid complex tetrakis(thiourea)cobalt chloride (TTCoC) from an aqueous solution of thiourea and cobalt chloride through a slow evaporation method that yields good-quality crystals. Different analyses confirmed that TTCoC crystal is a good nonlinear optical mate...

The Retinal Pigment Epithelium (RPE) is a monolayer of cells located above the choroid. It mediates human visual cycle and nourishes photoreceptors. Hypoxia-induced oxidative stress to RPE is a vital cause of retinal degeneration such as the Age-related Macular Degeneration. Most of these retina...

The electrochemical behavior and electrodeposition of cobalt was investigated in the choline chloride-urea deep eutectic solvent containing cobalt chloride. Cyclic voltammetry was used to study the effect of temperature and concentration on the electrochemical behavior of cobalt. Chronoamperomet...

Antimony (Sb)-doped tin oxide (ATO) nanoparticles with various doping amounts were prepared by solvothermal synthesis. ATO thin films were fabricated on glass substrates via spin coating using a prepared ATO nanoparticle suspension solution. The effect of doping amount and annealing temperature ...

Antimony-doped tin oxide (ATO) nanoparticles with an average size of ~ 6 nm were prepared by co-precipitation and subsequent heat treatment. Graphitic carbon nitride (g-CN)/ATO hybrid nanocomposite was designed by the combination of thermally synthesized g-CN and ATO nanoparticles by ultrasonica...

Birnessites are abundant naturally occurring minerals with high sorption and oxidation capacity that could therefore play an important role in antimony (Sb) migration and transformation. There are various types of birnessites in the environment. However, little is known about the similarities an...

In this study, the hydrolysis of Sb to form Sb4Cl2O5 from a Sb-Fe mixed solution was first investigated using NH4OH as a neutralizer. The effects of different process parameters on the hydrolysis ratio of antimony, separation coefficient of Sb-Fe and product features were investigated in detail....

Sodium-ion batteries (SIBs) have attracted lots of significant interests, arising from in regard to the development of developing a low-cost energy storage system for renewable energy. Antimony-based materials with that have high theoretical storage capacities of Na+ have become one of the most ...

An organic-inorganic non linear optical (NLO) crystal L-Valine Potassium Penta Borate octa hydrate (LVPPB) single crystals were synthesized and grown by slow evaporation technique at ambient temperature.
