title: Investigation of methanol diffusion dynamics in SAPO-34 pores

description: Zeolites and zeo-type materials with porous architecture are widely used as adsorbents or catalysts in a myriad of commercial petrochemical and environmental processes including production of transportation fuels (such as gasoline) and exhaust after-treatment of an end-pipe of a mobile (car or truck) or stationary source (industrial chimney). The process involves the diffusion of molecules through the zeolite pores to and from the active sites, which are often Brønsted acidic sites. The diffusion characteristics of the reactants and products determine the chemical kinetics of a reaction. The present study aims to understand the diffusion properties of methanol in SAPO-34 material, which is the part of the methanol to olefins (MTO) process that can produce a carbon neutral renewable polyethylene and polypropylene from renewable methanol feed stock. The study enables us to better understand and tune the MTO activity, product selectivity and catalyst stability.

title: The application of INS to investigate the isomerization of xylene in zeolites (MAPS)

description: The global demand for p-xylene production is significant, totalling 37 Mt in 2014. Following on from a recent initiative to use neutron scattering to investigate a single class of ZSM-5 catalyst for the methanol-to-hydrocarbon reaction, a new academic/industrial project is now looking at the application of different classes of ZSM-5 catalysts for the formation of p-xylene. This proposal seeks to use MAPS to characterise molecular entities retained by the catalyst as a function of reaction temperature. The resulting profile will provide information on the deactivation characteristics of a new industrial grade ZSM-5 sample active for p-xylene formation. This MAPS application is linked to associated TOSCA and QENS proposals.

title: Commensurate Magnetic and Superconducting Transitions in a Candidate Topological Superconductor

description: We propose to understand the interplay between superconductivity and magnetism in the candidate topological superconductor heterostructure system composed of Cr-doped (Bi,Sb)2Te3 (CBST) and FeTe. CBST is a magnetic topological insulator while FeTe is an antiferromagnetic analogue of the well-know superconductor FeSe. Individually non-superconducting, these elements manifest an emergent interfacial superconductivity when interfaced. Our preliminary muon spin relaxation (µSR) data and scanning tunneling microscopy indicates that magnetism and topologically nontrivial surface states are preserved in the superconducting state. The combination of magnetism, superconductivity, topologically protected chiral surface states makes these systems ideal candidates for realizing Majorana physics. Even more interesting, our µSR data suggests that a transition to a henceforce unknown magnetic ground state in the FeTe is critical for supporting the superdoncutivity, raising the possibility that CBST/FeTe is a spin-triplet superconductor. It is of course critical to understand the magnetic transition revealed by µSR, and we consequently propose to perform thin film neutron diffraction on WISH to precisely identify how the magnetic ground state evolves across the superconducting transition.

title: In-Situ investigation of Residual stress and Crystallographic Texture Evolutions of 17-4 PH Stainless Steel during High temperature Annealing

description: The 17-4 PH stainless steel has wide range of applications in power plants, marine, and chemical industries due its good mechanical properties and corrosion resistant. Although, producing 17-4 PH alloy via Additive Manufacturing (AM) technology has great advantages, numerous undesired results encountered. During selective laser melting (SLM) process, high temperature gradient can be generated within the AM produced part as a results of high energy input at local scanning points leading to increased residual stresses. Furthermore, the residual stresses promote premature failures of the mechanical parts used in services. Therefore, it is critical to investigate the residual stresses generation during 3D printing and understand the recovery mechanism during post processing heat treatment. The SLM scanning strategy parameters have a great influence on the generated microstructure, texture and post fabrication treatments. Therefore, it is important to investigate the SLM scanning strategy and post processing parameters influences on residual stress generation and texture evolution. Here we will particularly focus on understanding the effect of different 3D printing scanning path and post processing parameters. Each of these scan paths will result in a different residual stresses distribution and microstructure/texture evolution during printing and post processing.

title: CANADIAN: Momentum dependence of crystal field levels in CeRhIn5

description: In Kondo systems, localized f-electron states hybridize with itinerant electrons, leading to an emergent many-body state. Modern electronic structure calculations indicate that excited crystal electric field (CEF) and spin-orbit levels of the f-electron manifold need to be considered in strongly correlated metals such as the Kondo materials. Recent RIXS and ARPES experiments both indicate that these excited states acquire momentum dependence due to Kondo hybridization. Through the dynamical magnetic susceptibility, neutron scattering should access another aspect of this interesting momentum dependence. Yet, we are not aware of any single crystal neutron scattering studies of heavy fermion materials that could shed light Q-dependences of CEF levels. To investigate this subject, we propose to measure the single crystal inelastic spectrum of the heavy fermion material CeRhIn5 with the MAPS spectrometer with an incident energy of 50 meV. We request a total of 8 days to measure Q-dependences of the CEF levels in the antiferromagnetic, coherent paramagnetic and incoherent paramagnetic phases. The experiment will be performed on a well-characterized sample that has already been used to study the low-energy spin wave excitations.

title: PDF Study of Dynamic Correlated Disorder in the Hydride Ion Conductor Ca2NH

description: Calcium nitride-hydride (Ca2NH) has been shown to promote mild-condition ammonia synthesis as a co-catalyst (Kitano et al., Chem. Sc., 2016). Kitano et al. suggested Ca2NH acted as a hydrogen sink freeing up active sites on the transition metal (Ru) for further disassociation of N2 and H2 gases. EIS conducted at the University of St Andrews shows temperature dependent conductivities associated with type-II (thermally induced) ionic conductors (Boyce, Physics Reports, 1979). A previous QENS experiment (RB 1720393) showed significant Q-dependent broadening associated with this system, strongly indicating H- diffusion. Thus, it’s likely that the ionic conductivity of systems like Ca2NH play a significant role in promoting ammonia synthesis. A PDF experiment could explore the nature of this ionic conductivity and its relation to the structure of Ca2NH. Recent research has pin-pointed correlated disorder as a potential source for high ionic conductivities measured in solid-state systems (Keen & Goodwin, Nature, 2015). Analysis of our previous PDF experiment (RB 1610383) will soon be published in a Chemistry of Materials article outlining the relationship between correlated disorder and ionic conductivity in the superionic conductor BaH2. A clear understanding of the relationship between structure, correlated disorder, and ionic conductivity in the Ca2NH system will benefit future research into nitrogen-hydrogen based co-catalysts for mild-condition ammonia synthesis.

title: Low energy phonon dynamics of graphene-like monolayers

description: There is emerging interest in the deformation dynamics of graphene and 2D graphene-like materials that couple to the electronic, optical, mechanical and thermal properties. Most of these studies have relied on molecular dynamics simulations to predict the occurrence of rippling and buckling deformations developed in relation to low energy and long wavelength phonons involving out- of-plane motions of the 2D structures. In the course of a series of QENS (quasi- elastic neutron scattering) measurements designed to investigate the dynamics of the polytriazine imide (PTI) carbon layers and H2O molecules intercalated within them, we discovered the existence of a low energy dispersive phonon. We associate it with buckling of the C6N9H3 nanosheets, that is predicted by ab initio density functional theoretical (DFT) and quantum molecular dynamics (QMD) calculations. This would represent the first observation of the low energy phonon dynamics in graphene-related nanomaterials using QENS to probe the intralayer excitations via the H atoms bound to them within the intercalant free PTI (IF-PTI) structure.
