Investigations on Na+ ion conducting polyvinylidenefluoride-co-hexafluoropropylene/poly ethylmethacrylate blend polymer electrolytes

Sodium ion conducting composite polymer electrolytes (CPE) have been prepared by solution casting technique in the skeleton of polyvinylidenefluoride-co-hexafluoropropylene/poly ethylmethacrylate blend. The binary mixture of diethyl carbonate and ethylene carbonate were used as plasticizer, and nanosized Sb2O3 as filler. The sodium trifluoromethanesulfonate (NaCF3SO3) was used as an ionic conducting source. The a.c. impedance study shows that 10 wt% Sb2O3 containing CPE exhibits the maximum conductivity 0.569 mS cm-1 at ambient temperature. Molecular interactions of the constituents were analyzed by Fourier transform infra red spectroscopy. X-ray diffractogram reveals the amorphous nature of the CPE. A surface morphological feature was studied through scanning electron microscope. The activation energy and coherence length calculated were in support of the ionic transport.

A new family of NxOx pyridine-containing macrocycles: Synthesis and characterization of their Y(III), Ln(III), Zn(II), and Cd(II) coordination compounds

Reaction between 2,6-bis(2-formylphenoxymethyl)pyridine and N,N-bis(3-aminopropyl)methylamine or tris(2-aminoethyl)amine has been used as the starting point for the synthesis of seven oxa-aza macrocyclic ligands, five of them never reported previously. They all feature different pendant arms, which provide a wide range of coordination possibilities. The Schiff base macrocycles L1 and L4 and their reduced ligands L 2 and L5 are derived from 2,6-bis(2-formylphenoxymethyl) pyridine and tris(2-aminoethyl)amine or N,N-bis(3-aminopropyl)methylamine, respectively. The reaction of L1 with salicylaldehyde forms L 3, which features an imine bond in the pendant arm. The ligand L 5 has been the precursor for the pendant-armed L6 and L7, by alkylation of the free NH groups with methyl-imidazole or methyl-indole. By a template or a nontemplate approach, we have synthesized different mono- and dinuclear complexes with Y(III), Ln(III), Zn(II), and Cd(II) cations. Both the free macrocyclic ligands and their corresponding metal complexes have been characterized by microanalysis, IR, UV-vis, 1H and 13C NMR spectroscopy, FAB mass spectrometry, MS electrospray, and conductivity measurements.

Psychrophilin E, a new cyclotripeptide, from co-fermentation of two marine alga-derived fungi of the genus Aspergillus

Chemical investigation of the mycelial extract of a mixed culture of two marine alga-derived fungal strains of the genus Aspergillus has yielded one new cyclotripeptide, psychrophilin E (1), the recently reported oxepin-containing alkaloids, protuboxepin A (2) and oxepinamide E (3), together with three other polyketide derivatives (4-6). The chemical structure and relative and absolute configurations of psychrophilin E (1) were unambiguously established based on HRMS, 1D, 2D NMR and chiral-phase HPLC analysis of its hydrolysate. All the isolated compounds were assessed for their anti-proliferative activity against four different human cancer cell lines and some of them revealed selective activities. 2014

Filariasis in the new millennium

The Indonesian national fdariasis eradication program in its pursuit in obtaining microfilarial rates below 1% in filariasis endemic locations was on its right track until the monetary crisis started 3 years ago. This crisis which is not over yet at present is complicated by unstable public safety causing population shifts where people from filaria endemic locations seek refuge in non-endemic areas. This updated review will hopefully serve as a timely reminder to our physicians and health workers especially on the mode of filarial transmission as well as on its clinical presentations and presently accepted ways of management. This paper also will serve as an introduction into the present breakthroughs in this new millenium as noted in the field of diagnostics and simplified mass treatment schedules making it possible for the elimination of lymphatic filariasis as a public health problem. A global alliance under the guidance of the World Health Organization with support of the multinational pharmaceutical companies for providing free expensive medication as needed. The WHO also cooperates closely with the Tropical Diseases Research task forces of Filariasis Intervention Research and of Product Development, that in the end will provide the means to eradicate this disease for once and forever from the face of the earth.

Rock ‘n’ roll with gold: Synthesis, structure, and dynamics of a (bipyridine)AuCl3 complex

Our previously reported microwave synthesis of (N-N)AuCl2 + complexes (where N-N = 2,2?-bipyridine (bpy) and sterically unencumbered bpy derivatives) was used to prepare derivatives where the bpy moiety was substituted in the 6,6?-positions. Instead of the square-planar complexes, these reactions produced neutral (N-N)AuCl3 complexes. In these, the tethered N-N ligand is bonded such that one N occupies a regular position in the square coordination plane of the Au(III) center and the other N occupies a pseudoaxial position, interacting with Au through an elongated Au-N bond, as determined by X-ray crystallography of two complexes. Variable-temperature 1H NMR spectroscopy reveals that the two sites of the N-N ligand undergo exchange on the NMR time scale. For N-N = 6,6?-Me2bpy the activation parameters were determined to be DeltaH? = 8.5 ± 0.4 kcal mol-1 and DeltaS? = 0.7 ± 2.0 cal K-1 mol -1. The dynamic behavior of (6,6?-Me2bpy)AuCl 3 was investigated by a DFT computational study, which detailed the in-plane rocking motion seen by NMR as well as decoordination of the axially bonded N with concomitant rolling of half of the bpy moiety by rotation around the central C-C bond of the bidentate ligand.

An efficient synthesis of enantiomerically pure trans-N1,N 2-dimethylcyclohexane-1,2-diamine

A new pathway is described to produce a highly optically pure isomer of trans-N1,N2-dimethylcyclohexane-1,2-diamine through four simple steps. Reaction of cyclohexene oxide with aqueous methylamine, followed by cyclisation with Mitsunobu reagent and ring-opening reactions gave rac-trans-N1,N2-dimethylcyclohexane-1,2-diamine, and the enantiomers were obtained via a kinetic resolution using tartaric acid.

Salen-Based Conjugated Microporous Polymers for Efficient Oxygen Evolution Reaction

Exploring high-performance electrocatalysts, especially non-noble metal electrocatalysts, for the oxygen evolution reaction (OER) is critical to energy storage and conversion. Herein, we report for the first time that conjugated microporous polymers (CMPs) incorporating salen can be used as OER electrocatalysts with outstanding performances. The best OER electrocatalyst (salen-CMP-Fe-3) exhibits a low Tafel slope of 63 mV dec?1 and an overpotential of 238 mV at 10 mA cm?2. DFT and Grand Canonical Monte Carlo calculations confirmed that the significantly improved electrocatalytic properties can be attributed to the intrinsic catalytic activity of the salen moiety and the enrichment effect of the pore structures. This work demonstrates that salen-based conjugated polymers are a type of metal-coordinated porous polymer that show excellent catalyst performance.

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.Product Details of 20439-47-8, you can also check out more blogs about20439-47-8

Ivermectin ? Old Drug, New Tricks?

Ivermectin is one of the most important drugs in veterinary and human medicine for the control of parasitic infection and was the joint focus of the 2015 Nobel Prize in Physiology or Medicine, some 35 years after its remarkable discovery. Although best described for its activity on glutamate-gated chloride channels in parasitic nematodes, understanding of its mode of action remains incomplete. In the field of veterinary medicine, resistance to ivermectin is now widespread, but the mechanisms underlying resistance are unresolved. Here we discuss the history of this versatile drug and its use in global health. Based on recent studies in a variety of systems, we question whether ivermectin could have additional modes of action on parasitic nematodes.

Achieving superb sodium storage performance on carbon anodes through an ether-derived solid electrolyte interphase

High specific surface area carbon (HSSAC) is a class of promising high-capacity anode materials for sodium-ion batteries (SIBs). A critical bottleneck of the HSSAC anode, however, is the ultra-low initial coulombic efficiency (ICE) in commonly used ester-based electrolytes. This phenomenon further prohibits improving the specific capacity, long-term stability and rate capability of HSSAC anodes. This work reports the largely enhanced anode performance of several different HSSAC anodes in ether-based electrolytes. Very importantly, with the reduced graphene oxide (rGO) anode as one example, the ICE can be as high as 74.6% accompanied by a large reversible specific capacity of 509 mA h g-1 after 100 cycles at a current density of 0.1 A g-1. 75.2% of the capacity was retained after 1000 cycles at 1 A g-1. Even at a high current density of 5 A g-1, the specific capacity of the rGO anode can be obtained at 196 mA h g-1. This extraordinary performance is ascribed to the stable, thin, compact, uniform and ion conducting solid electrolyte interphase (SEI) formed in an ether-based electrolyte. Fortunately, this SEI-modifying strategy is generic and is independent of the specific microstructures of HSSAC anodes, indicating a promising avenue for manipulating the SEI on HSSAC anodes through utilizing ether solvents to enable achievement of high ICE for large-capacity HSSAC anodes for practical applications.
