Zhang, Haode published the artcileOrganic Ammonium Ion Battery: A New Strategy for a Nonmetallic Ion Energy Storage System, Recommanded Product: 2,5,8,11,14-Pentaoxapentadecane, the main research area is ammonium battery charge carrier nonmetallic ion energy storage system; Ammonium-Ion Batteries; Electrochemistry; Organic Electrolytes; Prussian White Analogues.

Nonmetallic ammonium (NH4+) ion batteries are promising candidates for large-scale energy storage systems, which have the merit of low molar mass, sustainability, non-toxicity and non-dendrite. Herein, for the first time, we introduce the novel organic ammonium ion batteries (OAIBs). Significantly, a manganese-based Prussian white analog (noted as MnHCF) as cathode exhibits a reversible capacity of 104 mAh g-1 with 98% retention over 100 cycles. We further demonstrate the electrochem. performance of the NH4+ ion full cell, which delivers a reversible capacity of 45 mAh g-1 with a broad electrochem. window. Combining ex situ XPS, ex situ XRD results and electrochem. properties, the NH4+ ion storage mechanism of MnHCF in a non-aqueous electrolyte is clearly revealed. This work verifies the feasibility of employing NH4+ ions as charge carriers in organic energy storage systems and provides new insights for designing organic nonmetallic ion batteries with broad electrochem. windows and high energy d.

Steinrueck, Hans-Georg published the artcileGeneral relationship between salt concentration and x-ray absorption for binary electrolytes, Application In Synthesis of 143-24-8, the main research area is salt concentration cell polarization absorption relaxation binary electrolyte.

We derive a general relationship between salt concentration and x-ray absorption for binary electrolytes. Volume and mass conservation are considered. The relationship can be used to measure salt concentration profiles via x-ray absorption imaging during cell polarization and relaxation. In conjunction with concentrated solution theory, the derived relationship is as a powerful tool to accurately determine transport coefficients such as cation transference number in ion battery electrolytes and to test thermodn. models. The relationship is electrolyte-agnostic, as long as the product between mass attenuation coefficient, inverse partial molar volume, and molar mass of the solvent and that of the salt are not equal.

Semenycheva, Lyudmila published the artcileFeatures of Polymerization of Methyl Methacrylate using a Photocatalyst-the Complex Oxide RbTe1.5W0.5O6, Quality Control of 143-24-8, the main research area is rubidium tungsten tellurate photocatalyst methyl methacrylate polymerization.

Radical polymerization of Me methacrylate in an aqueous emulsion was carried out using the complex oxide RbTe1.5W0.5O6 as a photoinitiator under visible light irradiation with λ = 400-700 nm. Study of the polymerization process and reaction products using methods of phys. and chem. anal. (GPC, IR, NMR, etc.) has shown that there are several directions of monomer transformations at the same time. Polymethyl methacrylate with Mn ∼ 140-145 kDa, produced in the organic phase, is a result of polymerization initiation by a hydroxyl radical formed due to complex transformations of electron-hole pairs during photocatalyst irradiation Moreover, the interaction of the hydroxyl radical with OH-groups on the complex oxide RbTe1.5W0.5O6 surface and the subsequent formation of oxygen-centered radicals lead to grafting polymer macromols. on the photocatalyst surface. In addition, Me methacrylate is able to oxidize to a cyclic dimer with terminal double bonds and form a polymer with cyclic dimer links due to coordination by double bonds on the RbTe1.5W0.5O6 surface. The high activity of the hydroxyl radical allows to obtain the graft copolymer PMMA-pectin by grafting the polymer product on the surface of the natural polymer-pectin. Comparison of the sponge morphol. of the graft copolymer PMMA-pectin and the initial pectin samples using the SEM has shown a noticeable difference in their structural and topol. organization. It is especially interesting in terms of studying the properties of the graft copolymer as a material for the scaffolds.

Li, Yun published the artcileSolubility Measurement and Thermodynamic Properties Calculation for Several CO2 + Ether Absorbent Systems, HPLC of Formula: 143-24-8, the main research area is solubility thermodn property carbon dioxide ether absorbent system.

Six phys. absorbents with the ether groups were selected for CO2 absorption: tetraethylene glycol di-Me ether (TEGDME), diethylene glycol monohexyl ether, 2-butoxyethyl ether, triethylene glycol monobutyl ether, ethylene glycol di-Bu ether, and dipropylene glycol di-Me ether (DPGDME). CO2 solubilities in these absorbents were measured at 273.15 and 283.15 K and 0-1.2 MPa. Henry’s constants of these CO2 + ether absorbent systems were calculated and analyzed at 273.15 K. The ether group is found more powerful than the methylene group, and the Et group is more effective than the hydroxyl group to improve the absorption ability of the absorbents. A lower temperature tends to facilitate the absorption process by increasing the absorption ability. Henry’s constants and mass solubilities of the ether absorbents were compared with those of the ionic liquids, common solvents, and other absorbents. TEGDME and DPGDME are potential absorbents according to the evaluation in both mole and mass fraction. The thermodn. properties, such as entropy, enthalpy, and Gibbs free energy of solution, for CO2 + the ether absorbent systems were calculated and discussed for potential development of corresponding CO2 capture processes.

Ma, Yijia published the artcileRecovery of Hydrogen and Sulfur by Electrolysis of Ionized H2S in an Amine-Containing Organic Electrolyte with Highly Temperature-Dependent Sulfur Solubility, HPLC of Formula: 143-24-8, the main research area is recovery hydrogen sulfur electrolysis ionization hydrogen sulfide.

Abundant hydrogen sulfide (H2S) from nature and industry has been considered a harmful substance. However, it is a potential resource if valuable H2 and elemental sulfur can be recovered from H2S. Herein, a new organic electrolyte system was constructed for H2S direct electrolysis using tetraethylene glycol di-Me ether as the solvent, ionic liquid [C3OHmim]BF4 as the supporting electrolyte, and monoethanolamine (MEA) as the absorbent for H2S. The as-prepared electrolyte was found useful as highly temperature-dependent on the sulfur solubility electrolyte with catalytic effects of sorbent MEA, conducive to solving passivation problems caused by sulfur adhesion in direct electrolysis of H2S and sulfur recovery in indirect electrolysis. Moreover, the as-obtained organic electrolyte showed certain stability with Faraday efficiency of H2 generated after three heating-electrolysis-cooling cycles, reaching 89%. In summary, the as-obtained electrolyte looks promising for efficient and continuous electrolysis of H2S.

Zhang, Qi published the artcileChloride Ion as Redox Mediator in Reducing Charge Overpotential of Aprotic Lithium-Oxygen Batteries, Recommanded Product: 2,5,8,11,14-Pentaoxapentadecane, the main research area is chloride ion lithium oxygen battery redox mediator reducing charge.

The aprotic lithium-oxygen (Li-O2) battery with a high theor. energy d. has been considered as a promising candidate for next-generation energy storage devices. However, the formation of insulating Li2O2 products is a major obstacle for realizing the high energy efficiency and long cycle life. Here, we report a new Cl-/Cl3- redox mediator to reduce the charge overpotential by a facile introduction of chloride ion (Cl-) additives into the organic electrolyte. The redox mediator can effectively promote the formation of the LiOH discharge product, and facilitate efficient LiOH decomposition Therefore, the cell with the Cl- additives possesses a significantly low charge overpotential of 0.29 V, an extended cycle life (up to 71 cycles) at a rate of 500 mA g-1 with a fixed capacity of 500 mAh g-1, and an enhanced rate capability. This study offers an effective approach to modulate discharge products from Li2O2 to LiOH and provides new insights toward the role of redox mediators through the addition of Cl- in Li-O2 battery systems.

Kitada, Atsushi published the artcileGlyme-lithium bis(trifluoromethylsulfonyl)amide superconcentrated electrolytes: salt addition to solvate ionic liquids lowers ionicity but liberates lithium ions, Recommanded Product: 2,5,8,11,14-Pentaoxapentadecane, the main research area is glyme lithium trifluoromethylsulfonyl amide superconcentrated electrolytes solvate ionic liquid.

Solvate ionic liquids (ILs) such as binary equimolar mixtures of glymes (ethyleneglycol-dimethylether or CH3(OCH2CH2)nOCH3) and lithium bis(trifluoromethylsulfonyl)amide (LiTf2N; Tf = SO2CF3) are known to show identical self-diffusion coefficients for glymes and Li+ ions. Here, we report that the addition of LiTf2N to the solvate ILs drastically changes their electrolyte properties. When the lithium salts are added to give the super-concentrated electrolytes with [O]/[Li+] = 3 (molar ratio of ether oxygen to Li+), ligand exchange or hopping conduction of Li+ takes place for triglyme (G3; n = 3) and tetraglyme (G4; n = 4). In addition, the Li+ transference number tLi+(EC), electrochem. measured under anion blocking conditions, increases about 3-6 times compared with the solvate ILs. Consequently, segmental motion of glymes apparently affects the transport properties even for the shorter G3 in the super-concentrated region. The relationship between the coordination structure and the transport properties are also discussed as a function of ionicity, the extent of the contribution of self-diffusion to the actual ion conduction. Plots vs ionicity demonstrate that a clear line can be drawn between the solvate ILs and the super-concentrated electrolytes.

Oyedeji, Ajibola Bamikole published the artcileMetabolite data of germinated Bambara groundnut flour and starch extracted with two different solvents, Product Details of C10H22O5, the main research area is germinated Bambara groundnut flour starch metabolite solvent extraction; Bambara groundnut; GC-HRTOF-MS; Germination; Metabolites; Solvent extraction.

The data presented in this study represents the profile of metabolites of germinated Bambara groundnut flour (GBF) and starch (GBS) extracted using two different extraction solvents. Bambara groundnuts obtained from a local agro market in Minna, Niger State, Nigeria were germinated at 28 ± 1°C for 24, 48 and 72 h, dried and then processed into flour and starch. Raw Bambara groundnuts (0 h) were also processed into flour and starch and served as controls. Samples at the different germination times were extracted using methanol/water (80:20vol./volume) and acetonitrile/methanol/water (40:40:20 volume/volume/v), concentrated, reconstituted and analyzed on a gas chromatog.-high resolution time of flight-mass spectrometer (GC-HRTOF-MS). Data obtained were classified into compound groups such as acids, alcs., cyclic compounds, esters, ketones, phytosterols, vitamins and many others, and their characteristics such as the retention time, observed mass, mol. formular and mean peak areas were reported. These data represent the collection of metabolites in GBF and GBS and may be useful for the identification and utilization of functional compounds in foods.

Dysprosium β-diketonate compounds have recently gained a lot of attention due to their intriguing multifunctional properties. In this paper, a series of “”Dy(hfa)3•glyme”” adducts have been prepared through a one-pot reaction, in dichloromethane, from dysprosium(III) acetate monohydrate, hexafluoroacetylacetone and glyme [Hhfa = 1,1,1,5,5,5-hexafluoroacetylacetone, glyme = bis-(2-methoxyethyl)ether, 2,5,8,11-tetraoxadodecane, 2,5,8,11,14-pentaoxapentadecane]. Based on the length of the polyether, various coordination frameworks have been obtained going from a mononuclear [Dy(hfa)3•diglyme] adduct, to a polymeric chain system for the [Dy(hfa)3•2H2O•triglyme], and an ionic structure for the [Dy(hfa)2•tetraglyme]+[Dy(hfa)4]-. The relationship between the coordination framework in the “”Dy(hfa)3•glyme”” series and the magnetic and luminescent properties has been deeply investigated.
