Simultaneous transport and coupling of ionic electronic charges is fundamental to electrochemical devices used in energy storage conversion, neuromorphic computing bioelectronics. While the mixed conductors enabling these technologies are widely used, dynamic relationship between generally poorly understood, hindering rational design new materials. In semiconducting electrodes, doping assumed be limited by motion ions due their large mass compared electrons and/or holes. Here, we show that...
Abstract Intentionally disordered metal–organic frameworks (MOFs) display rich functional behaviour. However, the characterisation of their atomic structures remains incredibly challenging. X-ray pair distribution function techniques have been pivotal in determining average local structure but are largely insensitive to spatial variations structure. Fe-BTC (BTC = 1,3,5-benzenetricarboxylate) is a nanocomposite MOF, known for its catalytic properties, comprising crystalline nanoparticles and...
Abstract Conjugated polymers are promising materials for thermoelectric applications, however, at present few effective and well‐understood strategies exist to further advance their performance. Here a new model system is reported better understanding of the key factors governing properties: aligned, ribbon‐phase poly[2,5‐ bis (3‐dodecylthiophen‐2‐yl)thieno[3,2‐b]thiophene] (PBTTT) doped by ion‐exchange doping. Using range microstructural spectroscopic methods, effect controlled...
In this work, we investigated the response of metal-organic framework MIL-125-NH2 to ball-milling. Both localised and bulk analyses revealed prolongued ball-milling results in a complete loss long-range structural order. Investigation disorder partial retention local bonding secondary building unit, suggesting structure collapse progressed primarily through metal-linker bond breakage. We explored photocatalytic performance materials, examined materials' band gap using UV-Vis reflectance spectroscopy.
Characterization of nanoscale changes in the atomic structure amorphous materials is a profound challenge. Established X-ray and neutron total scattering methods typically provide sufficient signal quality only over macroscopic volumes. Pair distribution function analysis using electron (ePDF) scanning transmission microscope (STEM) has emerged as method probing nanovolumes these materials, but inorganic glasses well metal-organic frameworks (MOFs) many other containing organic components...
Work of numerous research groups has shown different outcomes studies the transition from ferroelectric $\ensuremath{\alpha}$-phase to high temperature $\ensuremath{\beta}$-phase multiferroic, magnetoelectric perovskite Bismuth Ferrite (${\mathrm{BiFeO}}_{3}$ or BFO). Using perturbed angular correlation (PAC) method with $^{111m}\mathrm{Cd}$ as probe nucleus, $\ensuremath{\alpha}$ $\ensuremath{\beta}$ phase was characterized. The temperature, change crystal structure, and its parameters were...
pyXem 0.10.0 is the Q3 2019 minor release of pyXem, an open-source Python library for crystallographic diffraction. In this cycle we have added a significant amount new functionality to code, as summarized below. The API prior from v0.9.x has changed very minimally. Details all development associated with are available here. HyperSpy Extension & Lazy Signal Classes pyxem now registers hyperspy extension on installation. This means that and Component classes recognised by LazyDiffraction1D,...
