In this work quasielastic neutron scattering was used to study proton self-diffusion in mesoporous disordered and P6mm symmetry silica impregnated with two concentrations of phosphotungstic acid. Overall, the silica structure had a significantly greater effect on proton conduction and diffusion than phosphotungstic acid concentration, with higher proton conduction occurring for the P6mm symmetry silica samples. Quasielastic neutron scattering revealed two populations of protons diffusing through each sample, and that proton conduction is limited by the slower of these populations, which diffuse via a jump-diffusion mechanism. Whilst the fundamental jump-diffusion mechanism by which these slower protons moved was found to be similar for both silica supports and phosphotungstic acid concentrations, the faster diffusion occurring in P6mm structured silica arises from a lower residence time of protons moving between sites in the jump-diffusion model, suggesting a lower energy barrier.]]> Wed 30 May 2018 10:47:53 AEST ]]> Recent Advances in Silver Nanoparticle Containing Biopolymer Nanocomposites for Infectious Disease Control – A Mini Review Wed 30 Jan 2019 11:50:19 AEST ]]> Electrochemical Ion Transfer With Thin Films of Poly(3-octylthiophene) Wed 27 Nov 2019 14:16:39 AEST ]]> GalvaPot, a custom-made combination galvanostat/potentiostat and high impedance potentiometer for decentralized measurements of ionophore-based electrodes Wed 25 Nov 2015 15:18:16 AEST ]]> Formulation of DNA chimera templates: Effects on emission behavior of silver nanoclusters and sensing Wed 22 May 2019 12:57:42 AEST ]]> Nano-confined synthesis of highly ordered mesoporous carbon and its performance as electrode material for electrochemical behavior of riboflavin (vitamin B2) and dopamine Wed 20 Sep 2017 14:41:54 AEST ]]> Electron Hopping Between Fe 3 d States in Ethynylferrocene-doped Poly(Methyl Methacrylate)-poly(Decyl Methacrylate) Copolymer Membranes Wed 18 Apr 2018 16:20:53 AEST ]]> Coulometric Calcium Pump for Thin Layer Sample Titrations Wed 12 Feb 2020 14:04:41 AEST ]]> Advances in Potentiometry Wed 05 Jul 2017 14:41:55 AEST ]]> Ionophore-based ion-selective optical nanosensors operating in exhaustive sensing mode Wed 03 Jun 2015 16:26:48 AEST ]]> Visible light induced photoacid generation within plasticized PVC membranes for copper (II) ion extraction Wed 03 Jun 2015 16:26:46 AEST ]]> Chronopotentiometry of pure electrolytes with anion-exchange donnan exclusion membranes Wed 03 Jun 2015 16:26:38 AEST ]]> Ionophore-based optical sensors Wed 03 Jun 2015 16:19:42 AEST ]]> New Generation Antibacterial Nanofibrous Membrane for Potential Water Filtration Tue 28 Aug 2018 10:53:21 AEST ]]> Using Attenuated Total Reflection Fourier Transform Infrared Spectroscopy (ATR FT-IR) to study the molecular conformation of parchment artifacts in different macroscopic states Tue 27 Aug 2019 16:00:06 AEST ]]> Cover Picture: Electron Hopping between Fe 3 d States in Ethynylferrocene‐doped Poly(Methyl Methacrylate)‐poly(Decyl Methacrylate) Copolymer Membranes (Electroanalysis 4/2018) Tue 24 Apr 2018 16:16:27 AEST ]]> A Prototype of an Electromagnetic Induction Sensor for Non-Destructive Estimation of the Presence of Corrosive Chemicals Ensuing Concrete Corrosion Tue 21 May 2019 14:15:40 AEST ]]> PEDOT(PSS) as Solid Contact for Ion-Selective Electrodes: The Influence of the PEDOT(PSS) Film Thickness on the Equilibration Times Tue 20 Mar 2018 13:17:40 AEST ]]> Electroanalysis with Membrane Electrodes and Liquid–Liquid Interfaces Tue 19 Jan 2016 10:06:53 AEST ]]> Multiplexed Lateral Flow Devices for the Detection of Viral Nucleic Acids Tue 17 Sep 2019 10:44:39 AEST ]]> Characterization of Synthetic and Natural Product Pharmaceuticals by Functional Group Analysis using Electrospray Ionization-Ion Trap Mass Spectrometry: A Mini-Review Tue 16 Oct 2018 12:22:52 AEST ]]> Dereplication of phytochemicals in plants by LC-ESI-MS and ESI-MSn Tue 16 Oct 2018 11:58:57 AEST ]]> Essential oils from Leptospermums of the Sunshine Coast and Northern Rivers Regions Tue 16 Oct 2018 11:55:52 AEST ]]> A Negative Ion Mass Spectrometry Approach to Identify Cross-Linked Peptides Utilizing Characteristic Disulfide Fragmentations Tue 16 Oct 2018 11:49:06 AEST ]]> Negative ion cleavages of (M–H)− anions of peptides.

alcohol fuel cells more efficient for real world use 160°C) proton exchange membrane fuel cells (HT-PEMFCs) are solid energy conversion devices that electrochemically convert chemical energy (e.g., from alcohols) into electricity. HT-PEMFCs are more efficient than low temperature PEMFCs due to elimination of carbon monoxide poisoning and enhanced oxidation kinetics. Heteropoly acids (HPAs) such as Phosphotungstic acid (abbreviated as HPW) can be used to functionalize ordered mesoporous silica (abbreviated as MSN) to make nanocomposite PEMs [1]. While these nanocomposites have shown promising early results in HT-PEMFCs, the structure-activity relationship of proton exchange in these functional materials is yet to be established. Small angle X-ray scattering (SAXS) and high resolution-Fourier transform infrared (HR-FTIR) studies have shown that HPA functionalized mesoporous silica nanocomposites are similar in structure outside of subtle variations in FTIR spectra according to the inherent functional groups in the material. Further investigation of these phenomena is continuing, with the award of further HR-FTIR beamtime in July 2013. This research is exploring the best performance HPA-MSNs, in relation to composition, structural chemistry and proton diffusion mechanism, with subsequent evaluation of these materials in direct alcohol fuel cells (DAFCs).]]> Fri 08 Apr 2016 07:52:22 AEST ]]> Photoresponsive ion extraction/release systems: Dynamic ion optodes for calcium and sodium based on photochromic spiropyran Fri 08 Apr 2016 07:23:09 AEST ]]> A comprehensive study of ovine haemostasis to assess suitability to model human coagulation Fri 07 Nov 2014 13:24:56 AEST ]]> Direct Optical Carbon Dioxide Sensing Based on a Polymeric Film Doped with a Selective Molecular Tweezer-Type Ionophore Fri 07 Nov 2014 12:32:17 AEST ]]> All solid state chronopotentiometric ion-selective electrodes based on ferrocene functionalized PVC Fri 07 Nov 2014 12:15:18 AEST ]]> Direct Ion Speciation Analysis with Ion-Selective Membranes Operated in a Sequential Potentiometric/Time Resolved Chronopotentiometric Sensing Mode Fri 07 Nov 2014 12:14:06 AEST ]]> Detection Limits of Thin Layer Coulometry with lonophore Based Ion-Selective Membranes Fri 07 Nov 2014 12:01:38 AEST ]]> A label-free potentiometric sensor principle for the detection of antibody-antigen interactions Fri 07 Nov 2014 12:00:22 AEST ]]> Dynamic electrochemistry with ionophore based ion-selective membranes Fri 07 Nov 2014 11:53:50 AEST ]]> Potentiometric sensors with ion-exchange donnan exclusion membranes Fri 07 Nov 2014 11:49:13 AEST ]]> Direct Detection of Acidity, Alkalinity, and pH with Membrane Electrodes Fri 07 Nov 2014 11:38:01 AEST ]]> The crustacean ecdysone cassette: a gatekeeper for molt and metamorphosis Fri 07 Feb 2020 13:47:39 AEST ]]> CYP450s analysis across spiny lobster metamorphosis identifies a long sought missing link in crustacean development Fri 07 Feb 2020 13:20:31 AEST ]]> Multiplexed lateral flow biosensors: technological advances for radically improving point-of-care diagnoses Fri 07 Feb 2020 12:52:04 AEST ]]> A Calixarene-Based Ion-Selective Electrode for Thallium(I) Detection Fri 07 Feb 2020 11:56:09 AEST ]]> Advances in isothermal amplification: Novel strategies inspired by biological processes Fri 07 Feb 2020 11:56:09 AEST ]]> Development of an improved ligand mimetic calibration system for the analysis of iron(III) in seawater using the iron(III) chalcogenide glass ion selective electrode: A combined mechanistic and analytical study Fri 07 Feb 2020 11:49:01 AEST ]]> Review: a comprehensive summary of a decade development of the recombinase polymerase amplification Fri 04 Jan 2019 12:00:03 AEST ]]> Are the current Australian sun exposure guidelines effective in maintaining adequate levels of 25-hydroxyvitamin D?
