Platinum metals enter the environment primarily through the worldwide use of autocatalysts. The metals are released from the catalyst in the form of microparticles and nanoparticles, in elemental form, optionally in the form of surface-oxidized particles. Also important is the use of biologically active compounds of platinum group metals in oncological therapy, when they become the part of wastewaters. They move in all environmental compartments and are also subject to long-distance transport. However, they are still found in very low concentrations in the environment. Their direct determination is often difficult, using only highly sensitive analytical techniques. To use more common and more affordable techniques, a preconcentration step is necessary to increase their concentration to a measurable value. An overview of the application of preconcentration techniques and an overview of the current occurrence of platinum metals in individual matrices is presented.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 1119-97-7

(E)1-acetyl-[2-(3-methyl-2-butenyloxy)benzylidene]indolin-2-one (1) gives competition between the intramolecular Hetero Diels-Alder (HDA) (thermal conditions) and the intramolecular ene reaction (IER) (magnesium perchlorate – MP – catalyzed conditions). Several complexes derived from MP and chiral bis-oxazolines were found to be excellent chemo- and enantioselective catalysts with a different degree of selectivity depending on the substituents on the oxazoline ring. The most chemoselective oxazolinic ligand forced the reaction to give a ratio of [HDA]:[[IER] products 5:95. The trans-(4,5-diphenyloxazoline)-MP complex is the best enantioselective catalyst and the product of the IER of 1 can be prepared in 75% yield and 88% e.e..

With the increasing use of wormlike micelle solutions as rheological modifiers in many consumer products, the prediction of the behavior of these fluids has grown increasingly important in recent years. In this paper, the flow past a sphere falling at its terminal velocity through a column of a wormlike micelle solution is experimentally studied. The working fluid is an entangled wormlike micelle solution of 0.05 mol/l cetyletrimethylammonium bromide and 0.05 mol/l sodium salicylate dissolved in water. The rheology of the fluid is characterized in both shear and transient homogeneous uniaxial extension. Sphere-to-tube ratios of a/R=0.0625 and a/R=0.125 are investigated over a wide range of Deborah numbers. The drag on the sphere is initially found to decrease with increasing Deborah number because of shear thinning effects. As the Deborah number is increased, the establishment of a strong extensional flow in the wake of the sphere causes the drag to increase to a value larger than that of a Newtonian fluid with the same viscosity. At a critical Deborah number, the flow becomes unstable and fluctuations in the sedimentation velocity of the sphere are observed. Particle image velocity measurements are used to analyze the flow fields around the falling spheres. These measurements show the presence of a strong negative wake. For the unstable flows, the velocity flow field is observed to fluctuate between a negative and extended wake. Pointwise and full-field flow-induced birefringence measurements are used to track the evolution in the deformation of the wormlike micelle chains. Strong evidence is found that suggests that the flow instability is the result of a breakdown of the wormlike micelle network structure in the wake of the sphere. This breakdown is related to the filament rupture observed in the extensional rheology experiments.

The region of lyotropic liquid phase formed in the TTAB + water + decanol ternary system are reported. There is one isotropic phase (isotropic L1) and five anisotropic phases, namely nematic calamitic Nc, nematic discotic Nd, nematic biaxial Nbx, hexagonal E, lamellar D mesophases. The anisotropic phases were determined by polarized microscope. The textures of the present ternary system were discussed in comparison with the textures of the binary TTAB + water system and non-specific textures caused by mechanical deformations investigated.

Crosslinked cationic nanoscale networks with hydrophobic cores are an environmentally robust alternative to self-assembled polymeric drug delivery carriers with respect to therapeutic encapsulation and stability to dilution. However, the ability to tune the degree of PEG incorporated into nanogels during synthesis is more challenging. In this work, biodegradable cationic nanogels were synthesized by ARGET ATRP emulsion polymerization in a single step. The density of PEG in the final nanogels ranged from zero to 40 wt % and was dependent on the feed concentration of PEG monomer, surfactant concentration, surfactant hydrophilic?lipophilic balance, and the ratio of cationic to nonionic surfactant. A comprehensive analysis of nanogel material properties as a function of PEG graft density is presented including analysis of composition, monomer conversion, thermal properties, size, surface charge, and degradation. This study provides a robust analysis for the synthesis of degradable cationic nanogels via a controlled radical polymerization with predictable degrees of PEGylation.

Two terpyridine-containing siloles (1 and 2) have been synthesized and their optical and metal sensing properties have been investigated in this work. 1 and 2 display a high selectivity for Zn2+ in comparison with alkali and alkaline earth metal ions (Na+, K+, Mg2+, Ca2+) and other transition metal ions (Ba2+, Zn 2+, Fe2+, Pb2+, Ni2+, Co 2+, Hg2+, Ag+) upon excitation at 380 nm in THF. As being chemosensor, 1 with two terpyridine groups at both ends shows better Zn2+ sensing properties than 2 containing only one terpyridine group at end due to the formation of a metal-organic coordination oligomer or polymer.

Hypothesis: When tetradecyltrimethylammonium bromide, TTAB, is added to aqueous solution of sodium salicylate, NaSal, the threading of the aromatic anion into the micellar palisade leads to the formation of wormlike micelles. Based on the calorimetric titration of NaSal with TTAB, and on the lifetime of fluorescence of salicylate, we propose that the aggregation of the two components directly leads to the formation of wormlike micelles, without any pre-aggregation. Experiments: By using an isothermal titration calorimeter, aliquots of TTAB were added to a dilute solution of NaSal. The energy involved in each addition was then integrated and the variation of enthalpy was determined. In the same range of concentrations and molar ratios, the surface tensiometry and time-resolved emission spectroscopy experiments were performed. Findings: A very characteristic calorimetric signal associated with wormlike micelle formation was obtained, being the enthalpy variation of this process, DeltaWLMH298 0 < 0. When 1.2 mmol L?1 of NaSal is titrated with 11.0 mmol L?1 of TTAB at 298.15 K, DeltafH298 0 = ?10.31 kJ per mol of injectant. By adding TTAB to NaSal solution, two fluorescence lifetimes of salicylate were observed solely after wormlike micelle being formed. The correspondent lifetime values of 4.0 ns and 7.2 ns are respectively associated with the free and associated species of salicylate. The new results demonstrated that wormlike micelles are the first aggregate formed when TTAB is added to salicylate. This aspect is relevant for understanding the mechanism of wormlike micelles formation.

Dichloromethane solutions of the aqua complexes [(eta6-p-MeC6H4iPr)M(PN)(H 2O)][SbF6]2 are active catalysts for the Diels-Alder reaction between methacrolein and cyclopentadiene. The reaction occurs rapidly at room temperature with good exo:endo selectivity (from 85:15 to 96:4) and moderate enantioselectivity (up to 47%). The intermediate Lewis acid-dienophile compound (RRu and SRu)- [(eta6-p-MeC6H4iPr)Ru(PNInd)(methacrolein)] [SbF6]2 was isolated, and the molecular structure of the S epimer was determined by diffractometric means.
