Marine oil spills constitute an environmental disaster with severe adverse effects on the economy and ecosystem. Phase-selective organogelators (PSOGs), molecules that can congeal oil selectively from oil?water mixtures, have been proposed to be useful for oil-spill recovery. However, a major drawback lies in the mode of application of the PSOG to an oil spill spread over a large area. The proposed method of using carrier solvents is impractical for various reasons. Direct application of the PSOG as a solid, although it would be ideal, is unknown, presumably owing to poor dispersion of the solid through the oil. We have designed five cheap and easy-to-make glucose-derived PSOGs that disperse in the oil phase uniformly when applied as a fine powder. These gelators were shown to selectively congeal many oils, including crude oil, from oil?water mixtures to form stable gels, which is an essential property for efficient oil-spill recovery. We have demonstrated that these PSOGs can be applied aerially as a solid powder onto a mixture of crude oil and sea water and the congealed oil can then be scooped out. Our innovative mode of application and low cost of the PSOG offers a practical solution to oil-spill recovery.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 28244-94-2 is helpful to your research., 28244-94-2

In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction. 50675-18-8, Name is Tetrahydropyran-4-carbaldehyde, molecular formula is C6H10O2.

Rapid clinical progress of hepatitis C virus (HCV) replication inhibitors, including these selecting for resistance in the NS5A region (NS5A inhibitors), promises to revolutionize HCV treatment. Herein, we describe our explorations of diverse spiropyrrolidine motifs in novel NS5A inhibitors and a proposed interaction model. We discovered that the 1,4-dioxa-7-azaspiro[4.4]nonane motif in inhibitor 41H (GSK2236805) supported high potency against genotypes 1a and 1b as well as in genotype 1b L31V and Y93H mutants. Consistent with this, 41H potently suppressed HCV RNA in the 20-day RNA reduction assay. Pharmacokinetic and safety data supported further progression of 41H to the clinic.

Three novel coordination polymers of CoII and CuII with flexible ligands, namely [Co(oba)(dpa)]n (1), [Cu(oba)(dpa)]n (2) and [Cu(oba)(bpy)1/2]n (3) [H2oba = 4,4?-oxybis(benzoic acid), dpa = 2,2?-dipyridylamine, bpy = 4,4?-bipyridine] were synthesized by hydrothermal reactions and characterized by single-crystal X-ray diffraction, thermogravimetric analyses, elemental analysis and IR spectroscopy. X-ray diffraction analysis reveals that complexes 1 and 2 are isostructural. In complexes 1 and 2, the CoII and CuII ions are linked by flexible oba ligands to form 1D helical chain. These chains are further assembled into 3D supramolecular edifice via aromatic pi-pi stacking interactions and intermolecular hydrogen bonding. The CuII ions in complex 3 are linked by the carboxylate groups oba to form an eight-membered ring chains, the connectivity between the corner-shared eight-membered ring chains are further bridged by the bent oba ligands to produce 2D helical layer containing the right-handed helical chains. Furthermore, the adjacent helical layers are connected by bpy pillars to form a novel 3D framework with an unprecedented topology of (315·420·58·62). The magnetic properties of complexes 1-3 have also been investigated.

A document type is Article, introducing its new discovery.

A class of novel sugar-based surfactants named alkoxyethyl 2-acetamido-2-deoxy-alpha-D-glucopyranosides were constructed by the introduction of oxyethene fragment (-OCH2CH2-) in the traditional alkyl glycoside structure. Such alkoxyethyl 2-acetamido-2-deoxy-alpha-D-glucopyranosides with different length of alkyl chain were synthesized, and their single configurations were confirmed to be alpha-anomer by 1H NMR and HRMS analysis. Their water solubility, surface tension, emulsification, foaming and thermal stability were investigated, and the effect of alkyl chain length on their surface property was also compared. The water solubility of alkoxyethyl 2-acetamido-2-deoxy-alpha-D-glucopyranoside was significantly superior to that of alkyl 2-acetamido-2-deoxy-alpha-D-glucopyranoside without an oxyethene fragment. Their dissolution process was an endothermic process and was driven by entropy increment as well. Alkoxyethyl 2-acetamido-2-deoxy-alpha-D-glucopyranoside was disclosed to reduce significantly the surface tension of water. For both of CMC and gammaCMC, there was a decreasing trend with increasing of alkyl chain length. As increasing of alkyl chain length, the maximum surface adsorption (Gammamax) increased and the molecular cross-sectional area (Amin) decreased. They adsorbed preferentially on the solution surface and then formed spontaneously micelles in solution by the hydrophobic effect. Nonyloxyethyl 2-acetamido-2-deoxy-alpha-D-glucopyranoside had the best foaming and emulsifying properties. All glycosides are thermally stable below 270 C. In view of the improvement of the water solubility and maintainance of surface activity with the introduction of the hydrophilic spacer, the novel alkoxyethyl 2-acetamido-2-deoxy-alpha-D-glucopyranoside should be expected to develop further its multiple applications as a class of novel water-soluble sugar-based surfactants in the future.

Methylene bridged 2,2?-dipyridylamine (dpa) derivatives and their metal complexes possess outstanding properties due to their inherent structural flexibility. Synthesis of such complexes typically involves derivatization of dpa followed by coordination on metals, and may not always be very efficient. In this work, an alternative synthetic approach, involving the derivatization step after-rather than prior to-coordination of dpa on metal center, is proposed and applied to synthesis of a number of platinum(ii) complexes with substituted benzyldi(2-pyridyl)amines. Comparison with the more conventional synthetic route reveals greater efficiency and versatility of the proposed approach. The obtained complexes are not luminescent in solution at room temperature, but display blue phosphorescence emission (ca. 415 nm) with the lifetimes of mus order in glassy matrix at 77 K, with additional green (ca. 485 nm) and relatively long living (tau = 3.7 ms) emission in the case of iodine substituted derivative.

Ternary compounds formed between M , adenosine 5′-triphosphate , and bis(2-pyridyl)amine(bipyam) have been prepared The solid compounds are crystalline and have a stoicheiometry described by the formula M(Hatp)(Hbipyam)*nH2O (n = 2-9).X-ray powder diffraction patterns are similar.Potentiometric titrations in aqueous solution show the presence of two ionizable protons.Visible spectra suggest an octahedral co-ordination geometry.I.r. spectra indicated essentially the same type of metal-ligand interactions in all the complexes and show that Hatp(3-) co-ordinates to the metal through the oxygen atoms of the alpha, beta, and gamma phosphate groups.The ternary compounds where M = Mg(II)(1) or Ca(II)(2) have been studied by single-crystal X-ray diffration techniques and their molecular structures determined.The two species are isostructural and can be formulated as 22*9H2O (2).Both (1) and (2) crystallise in space group C2221 (Z = 4), with a = 22.734(3), b = 10.233(3), c = 30.997(4) Angstroem for (1) and a = 22.965(3), b = 10.154(3), c = 32.390(4) Angstroem for (2).X-ray diffraction data were collected on a Philips automatic diffractometer and the structures solved by direct methods using the SIR (Semi-invariant Representation) package and refined by full-matrix least squares to final R values of 0.111 and 0.124 (1 088 and 1 008 independent observed reflections) for (1) and (2) respectively.In the (4-) units the metal ions lie on a two-fold axis with an octahedral co-ordination geometry completed by the oxygen atoms of the alpha, beta, and gamma phosphate groups of two symmetry-related Hatp(3-) molecules.The co-ordination polyhedron of (1) is nearly regular but in (2) it is significantly distorted.The phosphate chains have a folded configuration in both (1) and (2).In both complexes there are no bonding interactions between the metal ions and the adenine base.The metal atoms of the (2+) cations are also located on two-fold axes while the six co-ordinated water molecules form hydrogen bonds with the phosphate chains.The Hbipyam(1+) molecules do not co-ordinate to the metal ions and are disordered around two-fold axes.Strong stacking interactions exist between Hbipyam(1+) and purine rings.
