Single-Event Effect Performance of a Commercial ReRAM

We show heavy ion test results of a commercial production-level ReRAM. The memory array is robust to bit upsets. However the ReRAM system is vulnerable to SEFI

Hydrogen bonding of molecular solutes in protic and aprotic ionic liquids

© 2018 The thermochemical study of hydrogen bonding of organic solutes in 1-methylimidazolium bis(trifluoromethylsulfonyl)imide ([MIM][NTf2]) was carried out. Activity coefficients at infinite dilution of organic compounds in [MIM][NTf2] were measured by gas-liquid chromatography at different temperatures between 303.15 and 343.15 K. The solution enthalpies of organic solutes in [MIM][NTf2] were determined from the temperature dependence of activity coefficients in the same systems. Solution enthalpies of solutes (propanol-1, meta-cresol, acetone, acetonitrile, diethyl ether, tetrahydrofuran, dichloromethane, trichloromethane, pyrrole) in 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide [BMIM][NTf2] were measured by using high-precision solution calorimetry. The hydrogen bond enthalpies of organic solutes in [MIM][NTf2] and [BMIM][NTf2] were calculated using a previously developed method. The hydrogen bond enthalpies of organic solutes in the protic ionic liquid [MIM][NTf2] were compared with the values in the aprotic ionic liquid [BMIM][NTf2], as well as with those in the molecular solvent pyrrole. The hydrogen bond enthalpies of proton acceptor molecules in [MIM][NTf2] differ significantly from zero unlike in [BMIM][NTf2]. Hydrogen bond enthalpies of proton acceptor molecules in [MIM][NTf2] and pyrrole are close

Enthalpies of solution and enthalpies of solvation in water: The anion effect in ionic liquids with common 1-ethyl-3-methyl-imidazolium cation

© Springer Science+Business Media New York 2015. Abstract Thermochemical studies of ionic liquids (ILs) in aqueous solution were carried out using solution calorimetry. Heat effects of dissolution in water at 298.15 K and molar limiting enthalpies of solution were measured for ILs having a common cation, 1-ethyl-3-methyl-imidazolium, connected with different anions: diethylphosphate, ethylsulfate, tetracyanoborate, thiocyanate, and trifluoroacetate. Molar enthalpies of solvation of ILs in water were derived from experimental data for solution and vaporization enthalpies. Enthalpic data were correlated with ionic liquid specific parameters and descriptors. The best correlation was observed with hydrogen-bonding interaction energies. This result confirmed that hydrogen bonding is one of the main types of intermolecular interactions inherent for ILs in aqueous solutions

Thermocatalytic upgrading of heavy oil by iron oxides nanoparticles synthesized by oil-soluble precursors

© 2018 Elsevier B.V. Thermocatalytic upgrading of heavy crude oil at reservoir temperature and pressure has been studied. The objective of the present work was to investigate the efficiency of the compounds based on iron (iron carbonyls, iron oxide, metallic iron) on thermocatalytic upgrading process of heavy crude oil at reservoir temperature and pressure (5.0 MPa and up to 523.15 K). The viscosity reducing was used as the main parameter for determination of the efficiency of thermocatalytic upgrading. The effect of structure of the catalyst precursor on the composition of SARA fractions after thermal catalytic upgrading of crude oil was analyzed. A destruction of mainly resin fraction was found to occur during thermocatalytic upgrading of heavy crude oil. The composition and structure of catalysts after crude oil upgrading were determined by the X-powder diffraction and SEM methods. An impact of catalyst (Fe3O4) particle size on the efficiency of crude oil thermocatalytic upgrading process was revealed

Experimental and Theoretical Thermodynamic Study of Distillable Ionic Liquid 1,5-Diazabicyclo[4.3.0]non-5-enium Acetate

© 2016 American Chemical Society.A thermochemical study of the protic ionic liquid 1,5-diazabicyclo[4.3.0]non-5-enium acetate ([DBNH][OAc]), a prospective cellulose solvent considered for the Ioncell-F process, was carried out. The heat capacities of 1,5-diazabicyclo[4.3.0]non-5-ene (DBN) and [DBNH][OAc] were measured by differential scanning calorimetry (DSC) at 223-323 and 273-373 K temperature ranges, respectively. The enthalpies of fusion and synthesis reaction of [DBNH][OAc] were measured by DSC and reaction calorimetry, respectively. The gas-, liquid-, and solid-phase enthalpies of formation of [DBNH][OAc] and DBN were determined using calorimetric and computational methods. The enthalpy of vaporization of [DBNH][OAc] was estimated from the formation enthalpies. The activity coefficients at infinite dilution of 17 and the enthalpies of solution at infinite dilution of 25 organic solutes in [DBNH][OAc] were measured by gas chromatography and solution calorimetry methods, respectively. The obtained data will be used in the design and optimization of the Ioncell-F process
