In this work, new catalyst for the direct electro-oxidation of dimethyl ether (DME) was synthesized and studied using an array of techniques. One of the most prominent catalysts for this reaction, platinum copper alloy (PtCu), was synthesized in an easy and low cost approach. Structural characterizations such as X-ray diffraction (XRD), scanning electron microscopy (SEM), high resolution transmission electron microscopy (HR-TEM) and elemental analysis revealed that the synthesized PtCu nanoparticles (3 nm on average), formed homogeneous NanoChains without aggregation of metallic platinum or copper...

BACKGROUND: Diabetic macular edema (DME) is resulted from the retinal microvascular leakage that accompanies the breakdown of blood-retinal barrier. Triamcinolone acetonide (TA) is a therapeutic agent for DME, but since the detailed mechanism of action of TA is not known, part of its action was examined. METHODS: In vitro model to enhance the permeability of human retinal microvascular endothelial cells (HRMECs) was constructed by using DME-related cytokines such as vascular endothelial growth factor (VEGF), tumor necrosis factor-α (TNF-α), and interleukin-1β (IL-1β)...

The metal-organic frameworks Zr6O4(OH)4(bpydc)6 (1; bpydc(2-) = 2,2'-bipyridine-5,5'-dicarboxylate) and Zr6O4(OH)4(bpydc)0.84(bpdc)5.16 (2; bpdc(2-) = biphenyl-4,4'-dicarboxylate) were readily metalated with Ni(DME)Br2 (DME = dimethoxyethane) to produce the corresponding metalated frameworks 1(NiBr2)6 and 2(NiBr2)0.84. Both nickel(ii)-containing frameworks catalyze the oligomerization of ethylene in the presence of Et2AlCl. In these systems, the pore environment around the active nickel sites significantly influences their selectivity for formation of oligomers over polymer...

An efficient protocol for the synthesis of cyanoarenes has been developed via an iron-catalyzed chemoselective [2 + 2 + 2] cycloaddition reaction of diynes with alkynylnitriles under mild reaction conditions with good to excellent yields. The reaction is catalyzed by the combination of FeCl2·4H2O as a metal source, 2-(2,6-diisopropylphenyl)iminomethylpyridine (dipimp) as a ligand, and Zn as a reducing agent in DME solvent. The protocol was further extended to the synthesis of 2,2'-dicyanobiarene skeletons from the reaction of tetraynes with alkynylnitriles...

The solution structures, stabilities, physical properties, and reactivities of sodium diisopropylamide (NaDA) in a variety of coordinating solvents are described. NaDA is stable for months as a solid or as a 1.0 M solution in N,N-dimethylethylamine (DMEA) at -20 °C. A combination of NMR spectroscopic and computational studies show that NaDA is a disolvated symmetric dimer in DMEA, N,N-dimethyl-n-butylamine, and N-methylpyrrolidine. Tetrahydrofuran (THF) readily displaces DMEA, affording a tetrasolvated cyclic dimer at all THF concentrations...

Diabetic retinopathy (DR) is the leading cause of vision loss in people under 65 years of age. Diabetic macular edema (DME) is the most common cause of moderate visual impairment in individuals with DR. Until recently, focal or grid laser photocoagulation has been the standard of care for DME. Laser photocoagulation has been shown to stabilize vision and prevent moderate vision loss. Recent studies on the effect of anti-vascular endothelial growth factor (VEGF) substances in DME, showed resolution of the edema and visual acuity gain...
