This work provides a systemic comparison for ARGET ATRP and UV-initiated polycationic nanoparticles for drug delivery and a guide to deciding which type of polycationic nanoparticles have the best properties for specific applications. Polycationic nanoparticles were synthesized using a previously developed UV-initiated photoemulsion polymerization or a newly developed ARGET ATRP synthesis technique. The effect of the ratio of hydrophobic monomer in the feed was evaluated. Increasing the feed ratio of hydrophobic monomer was necessary to maintain biocompatibility and pH-responsive membrane disruptive characteristics when switching from the UV-initiated polymerization to ARGET ATRP. The resulting polycationic nanoparticles have utility as drug delivery carriers for hydrophobic drugs and/or nucleic acids.

Fluid flow profiles in free liquid films stabilised by anionic and cationic surfactants under an external electric field were investigated. Depthwise velocity fields were measured at the mid region of the free liquid film by confocal micron-resolution particle image velocimetry and corresponding numerical simulations were performed using Finite Element Method to model the system. Depthwise change in velocity profiles was observed with electroosmotic flow dominating in the vicinity of the gas?liquid and solid?liquid interfaces while backpressure drives fluid in the opposite direction at the core of the film. It was also found that the direction of the flow at various sections of the films depends on the type of surfactant used, but flow features remained the same. Numerical simulations predicted the flow profiles with reasonable accuracy; however, asymmetry of the actual film geometry caused deviations at the top half of the computational domain. Overall, electroosmotic flow profiles within a free liquid film are similar to that of the closed-end solid microchannel. However, the flow direction and features of the velocity profiles can be changed by selecting various types of surfactants. The free liquid films thickness was selected to match dimensions of foam Plateau border. Hence, these findings will be useful in developing a separation system based on foam electrokinetics.

Observation of the relations of the beta-lactum antibiotic drug levofloxacin hemihydrate (LFH) with of tetradecyltrimethylammonium bromide (TTAB) has been carried out by conductivity measurement technique in aqueous solution of alcohols and polyols at single fixed temperature (303.15 K) for different concentrations and at different temperatures (298.15?318.15 K) with interval of 5.0 K for one selected fixed concentration. For TTAB + LFH mixture with alcohols/polyols, a single critical micelle concentration (cmc) was found in this study. In presence of alcohols, the values of cmc for mixed systems LFH + TTAB exhibited higher (except for ethanol at 298.15 K) in magnitude in compare to their absence. This showed that the micellization of the mixture of LFH and TTAB was unfavorable to some extent in attendance of alcohols. In attendance of polyols, the cmc values for mixed systems LFH + TTAB was obtained smaller in scale in compare to their absence. This exhibited the early micellization of the mixture of LFH and TTAB. Values obtained for DeltaG0 m were negative, which indicate naturalness of the present study. The other kinds of thermodynamic parameters such as transfer enthalpy (DeltaH0 m.tr), transfer free energy (DeltaG0 m.tr), and transfer entropy (DeltaS0 m.tr) were also observed and demonstrated carefully. The compensation temperature (Tc) as well as the intrinsic enthalpy gain (DeltaH0? m) were also determined and interpreted. Moreover, the standard molar heat capacity (DeltaC0 m) for mixed system was evaluated and explained for the studied system.

The electronic absorption and resonance Raman spectra of the reduction products of some tris(5,5′-substituted bipyridine) complexes of iron and osmium provide “model” behavior for single-ligand localized redox orbitals.While the electron-withdrawing nature of the ethylcarboxy and phenyl substituents allows for the stable electrochemical addition of six electrons, the physical measurements are explicable within the framework developed for the tris bipyridine compounds, for which only the first three reduction products have been studied.Therefore, addition of more than one electron per ligand does not disrupt the localization mechanism for this set of iron and osmium complexes.Furthermore, the effects of ? back-bonding to these ligands are explored by comparing the results for the different metals.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Reference of 1762-46-5, you can also check out more blogs about1762-46-5

The Re(I) coordination compounds fac-Re(deeb)(CO)3(X), where deeb is 4,a¿²-(COOEt)2-2,2a¿²-bipyridine and X is I-, Br-, Cl-, or CN-, and [fac-Re(deeb)(CO)3(py)](OTf), where OTf- is triflate anion and py is pyridine, have been prepared, characterized, and anchored to nanocrystalline (anatase) TiO2. In regenerative solar cells with 0.5 M LiI-0.005 M I2 acetonitrile electrolyte, the Re(I) compounds convert absorbed photons into electrons efficiently. The rate of interfacial charge separation could not be time resolved, kcr > 108 s-1. Thermodynamically favorable recombination of the injected electron in TiO2 with the oxidized sensitizer requires milliseconds for completion. Charge recombination kinetics have been quantified on a 10-7-s and longer time scale and are insensitive to the Re sensitizer employed. The charge recombination kinetics have been contrasted with other sensitized TiO2 materials and are insensitive to an a¿¼960-mV change in apparent driving force. The results suggest that charge recombination is rate limited by diffusional encounters of the injected electron with the oxidized sensitizer. A 1999 American Chemical Society.

Shear-induced multilamellar vesicle (MLV) formation has been studied by coupling the small-angle neutron scattering (SANS) technique with neutron spin echo (NSE) spectroscopy. A 10% mass fraction of the nonionic surfactant pentaethylene glycol dodecyl ether (C12E5) in water was selected as a model system for studying weak inter-lamellar interactions. These interactions are controlled either by adding an anionic surfactant, sodium dodecyl sulfate, or an antagonistic salt, rubidium tetraphenylborate. Increasing the charge density in the bilayer induces an enhanced ordering of the lamellar structure. The charge density dependence of the membrane bending modulus was determined by NSE and showed an increasing trend with charge. This behavior is well explained by a classical theoretical model. By considering the Caille parameters calculated from the SANS data, the layer compressibility modulus B is estimated and the nature of the dominant inter-lamellar interaction is determined. Shear flow induces MLV formation around a shear rate of 10 s-1, when a small amount of charge is included in the membrane. The flow-induced layer undulations are in-phase between neighboring layers when the inter-lamellar interaction is sufficiently strong. Under these conditions, MLV formation can occur without significantly changing the inter-lamellar spacing. On the other hand, in the case of weak inter-lamellar interactions, the flow-induced undulations are not in-phase, and greater steric repulsion leads to an increase in the inter-lamellar spacing with shear rate. In this case, MLV formation occurs as the amplitude of the undulations gets larger and the steric interaction leads to in-phase undulations between neighboring membranes.

Synthesis of multilayered composite polymer particles comprising mainly poly(iso-butyl methacrylate)-block-polystyrene (PiBMA-b-PS) has been carried out by the use of two-step activator generated by electron transfer for atom transfer radical polymerization (AGET ATRP) in aqueous microsuspension. PiBMA-Br macroinitiator seed particles were prepared in the first step, followed by swelling with styrene and second step (seeded) polymerization. The blocking efficiency in the second step was found to be crucial with regards to the resulting particle morphology. A disordered sea-island morphology was obtained when the blocking efficiency was 47% (73% conversion), whereas a blocking efficiency of 61% (71% conversion) resulted in the formation of multilayered particles. High blocking efficiency can be achieved by careful adjustment of the activation rate by proper choice of polymerization temperature and amount of reducing agent (ascorbic acid).
