A 3Dmetal-organic framework (MOF) with acid-base pairs in its coordination space that efficiently conducts protons under both anhydrous and humid conditions has now been developed. The anhydrous proton conductivity for this MOF is among the highest values that have been reported for MOF materials, whereas its water-assisted proton conductivity is comparable to that of the organic polymer Nafion, which is currently used for practical applications. Unlike other MOFs, which conduct protons either under anhydrous or humid conditions, this compound should represent a considerable advance in the development of efficient solid-state proton-conducting materials that work under both anhydrous and humid conditions.</p>10aconducting materials10afuel cells10ametal-organic frameworks10aporous materials10aproton conduction1 aNagarkar, Sanjog, S.1 aUnni, SreeKuttan, M.1 aSharma, Amitosh1 aKurungot, Sreekumar1 aGhosh, Sujit, K.  uhttps://library.ncl.res.in/content/two-one-inherent-anhydrous-and-water-assisted-high-proton-conduction-3d-metal-organic-002007nas a2200229   4500008004100000022001400041245014800055210006900203260007500272300001400347490000700361520110400368653002501472653002101497653003101518653001401549653001801563100002201581700002601603700001601629856013201645       2016                        eng d  a1439-423500aComparative investigation of the ionicity of aprotic and protic ionic liquids in molecular solvents by using conductometry and NMR spectroscopy0 aComparative investigation of the ionicity of aprotic and protic   aPOSTFACH 101161, 69451 WEINHEIM, GERMANYbWILEY-V C H VERLAG GMBHcAPR  a1006-10170 v173 a<p>Electrical conductivity (sigma), viscosity (), and self-diffusion coefficient (D) measurements of binary mixtures of aprotic and protic imidazolium-based ionic liquids with water, dimethyl sulfoxide, and ethylene glycol were measured from 293.15 to 323.15K. The temperature dependence study reveals typical Arrhenius behavior. The ionicities of aprotic ionic liquids were observed to be higher than those of protic ionic liquids in these solvents. The aprotic ionic liquid, 1-butyl-3-methylimidazolium tetrafluoroborate, [bmIm][BF4], displays 100% ionicity in both water and ethylene glycol. The protic ionic liquids in both water and ethylene glycol are classed as good ionic candidates, whereas in DMSO they are classed as having a poor ionic nature. The solvation dynamics of the ionic species of the ionic liquids are illustrated on the basis of the (HNMR)-H-1 chemical shifts of the ionic liquids. The self-diffusion coefficients D of the cation and anion of [HmIm][CH3COO] in D2O and in [D-6]DMSO are determined by using H-1 nuclei with pulsed field gradient spin-echo NMR spectroscopy.</p>10aconducting materials10aElectrochemistry10aelectrostatic interactions10aIon pairs10aionic liquids1 aThawarkar, Sachin1 aKhupse, Nageshwar, D.1 aKumar, Anil  uhttps://library.ncl.res.in/content/comparative-investigation-ionicity-aprotic-and-protic-ionic-liquids-molecular-solvents-using
