title: Excitation spectrum of isotope-enriched Sr2IrO4

description: Sr2IrO4 is an important material in condensed matter physics, having been discovered to host a novel Jeff=½ Mott insulating state.Yet while magnetic fluctuations play a crucial role in the physical phenomena, investigations using neutrons have been severely hampered by the large neutron absorption cross section of the natural isotopic mixture of Ir. RIXS and optical methods have been used to study aspects of the excitation spectrum of Sr2IrO4 but the microscopic origins of some features remain a mystery, particularly those in the region of 400 meV. Our experiment plans to complement these previous studies with a neutron scattering experiment made possible by our recently developed 193Ir isotope enrichment. This will give unique insights into the magnetic excitation spectrum of Sr2IrO4 relevant for its unusual physical properties.

title: Structure and Magnetism in Osmium Scheelites

description: Heat capacity and bulk susceptibility measurements show KOsO4 to be an antiferromagnetic with modest Neel temperature but there is no indication of magnetic scattering in our preliminary Neutron diffraction data.  Our currently hypothesis is that this is a consequence of the weak magnetic form factor for the OsVII cation, and that establishing the magnetic structure will require higher quality data than achieved using the constant Wavelength diffractometer Echidna.  We note that the strongest magnetic peak in the neutron pattern of the isostructural and isoelectronic oxide KRuO4 has only 0.25% the intensity of the strongest Bragg reflection.  We anticipate the higher quality data available using WISH will enable us to understand the magnetic structure of this oxide.

title: Pressure-driven transformation of the Al coordination environment in oxide glass

description: In situ high-pressure neutron diffraction will be used to investigate the pressure-induced transformation of the Al coordination environment in a prototypical aluminosilicate glass at pressures up to 18 GPa. This element is an essential component in commercial display glass, where pressures in the gigapascal regime are easily generated by sharp-contact loading, and it is also an important component in magma-related glasses such as those from the CaO-MgO-Al2O3-SiO2 (CMAS) system. The pressure-induced conversion of tetrahedral AlO4 units into higher coordinated structural motifs will change the glass structure and the related material properties. It is important to investigate these processes in situ, in order to aid in the development of realistic models for, e.g., crack formation and propagation in display glass and related materials.

title: Partially disordered antiferromagnet phase of CsCoX3 (X=Cl, Br)

description: Systems of the CsCoX3 family form antiferromagnetic chains along the c-axis, and are arranged in a frustrated triangular arrangement in the ab-plane. Below 30K, both systems have been reported as forming a partially disordered antiferromagnet (PDA) phase. Recent work on Tb(HCOO)3 demonstrated that peaks in the magnetic neutron scattering, which if treated classically as Bragg peaks give rise to a PDA state, can be interpreted as maxima in the continuous diffuse scattering function, which correspond to a short-range ordered triangular Ising antiferromagnetic ("up-up-down") system. We propose the collection of the diffuse magnetic scattering of these systems in order to determine the nature of the PDA phase. We will require 2 days of beamtime on WISH to complete this study.

title: Excitation spectrum of the frustrated spinel GeCo2O4

description: The spinel GeCo2O4 is a promising compound to establish the consequences of geometrical frustration, as the magnetic Co2+ ions are on a network of corner-sharing tetrahedra (pyrochlore lattice). In addition, GeCo2O4 has been proposed as a potential spin and orbital ice. Understanding magnetic neutron diffuse scattering is often crucial to model competing interactions in frustrated magnets and to discover novel states of matter. The magnetic excitation spectrum of GeCo2O4 has been discussed as molecular excitations arising from a molecular ground sate, with spatial confinement induced by the possible co-existence of spin and orbital frustration. The aim of this proposed LET experiment is to obtain the low energy-transfer excitation spectrum  of GeCo2O4 to assess the impact of the data treatment on obtained magnetic diffuse scattering and hence on the "spin molecule" interpretation.

title: Understanding absorption of the energetic compound 3-nitro-1,2,4-triazol-5-one (NTO) for industrial wastewater remediation - MAPS

description: Insensitive munitions (IM) are munitions that will not react violently to accidental insult, thus they are relatively safe to handle and store. Ongoing research into IM has led to a resurgence of interest in the insensitive energetic material (secondary explosive) 3-Nitro-1,2,4-triazol-5-one (NTO). Unlike many energetic materials, NTO is surprisingly soluble in water and this leads to high levels of contamination in waste water streams from the industrial production of NTO. We have recently shown that this contamination can be conveniently cleaned from water using inexpensive sorption media such as activated carbon and basic alumina. We propose to investigate how NTO molecules interact with the surfaces of these sorption media to better understand how to improve the efficiency of waste water remediation efforts and reduce environmental exposure.

title: Foreign Policy Assertiveness of Six Major Nations

description: These variables are indicators of the foreign policy assertiveness of six major nations: Great Britain, France, Germany, Japan, Russia, and the United States.  Assertiveness is defined as the magnitude and intensity of actions by a nation to influence the foreign environment.  The following indicators are considered to reflect a nation's changing assertiveness:  the number of active duty naval personnel, the number of military personnel in foreign areas, the number of military attaches stationed abroad, and the number of diplomatic, consular, and other civilian government officials posted abroad.  Percentage changes in those indicators are considered to reflect the relative foreign policy assertiveness of the six nations.  The variables span the period from 1815 to 2005, but the coverage varies with each country.  Primary sources are used to the extent possible and are cited in each file.<br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br>

title: SANS study of interaction of iron with alginate

description: Bowel cancer is the fourth most common cancer in the UK with approximately 41,000 individuals in the UK diagnosed annually. Importantly it is estimated that over half of all bowel cancers are preventable through lifestyle changes including dietary modification. Previous studies demonstrate that diets rich in iron (e.g. red and processed meat) are a major risk factor. Recently, a polymer from seaweed called alginate has been shown to inhibit the uptake and transport of iron within human RKO colorectal carcinoma cells. Alginate is already used as a thickener and stabiliser in some foods and so could be a simple dietary additive to prevent or treat colorectal cancer. In our experiment at ISIS we will study the way that alginate interacts with iron in conditions similar to those found in the human gut. This will allow us to understand and optimise this promising system.

title: OX04

description: High-voltage power semiconductor devices, such as IGBTs, diodes and MOSFETs are susceptible to destructive failure due to terrestrial cosmic radiation (CR), notably the nucleon part. As a consequence, device development has to ensure adequate radiation hardness for every device technology. This aim can only partly be met by device and technology simulations and, therefore, also calls for extensive device tests. In order to reduce testing times accelerated irradiation tests at facilities with a nucleon energy spectrum close to the natural terrestrial CR are essential. The thus obtained failures rates will be compared to simulation predictions and storage tests. A further aim is the close comparison of results obtained at different accelerator facilities to ensure the relevance and quality of the device tests. This latter goal is important as no single radiation facility is able to perfect

title: Field induced z = 2 quantum criticality in a quasi-2d quantum magnet

description: Quantum phase transitions have recently received a lot of interest in various different fields of physics and the emergent universal properties have been studied in very different systems. Examples include 2D electron gases in semiconductor heterostructures, superfluid- or metal-insulator transitions, non-Fermi liquid behaviors or the condensation of quasi-particles in magnetic insulators. In our experiment we propose to study one particular field induced quantum critical point in a quasi-two-dimensional quantum magnet by means of inelastic neutron scattering. For the particular quantum critical point under study, d=2 corresponds to the upper critical dimension. Thus, the proposed experiment will allow as to study in detail quantum critical dynamics at the upper critical dimension.

title: Towards intermediate temperature diffusion: oxygen dynamics in Ce(Nb,V)O4+d

description: CeNbO4+d (0 &lt;= d &lt;= 0.33) displays mixed ionic-electronic conductivity at ~800 °C, where it adopts the tetragonal scheelite structure. Prior research has shown that partial substitution of Nb with V can lower the temperature of this transition, opening up the possibility of improved conductivity at temperatures closer to the intermediate range favoured for solid oxide fuel cell (SOFC) devices (500-700 °C). We will use quasielastic neutron scattering to study in detail the diffusion behaviour of oxide ions within the conductive scheelite phase of Ce(Nb,V)O4+d. Large single-crystal samples will enable to examine the distinct directional components of oxygen diffusion and compare the conduction behaviour to that determined theoretically for CeNbO4 and other candidate SOFC electrode materials with the scheelite structure.

title: Local structure in lanthanum oxyfluorides - probing ion transport in fuel cell materials

description: Mixed-anion compounds such as lanthanum oxyfluorides are increasingly attractive as materials in energy technology applications, such as fuel cells, electrolysers and permeation membranes. As the structures become more complex it is essential that a detailed understanding of the local structure, local anion/cation ordering and related anion migration pathways is determined. Here we focus on the lanthanum oxyfluorides and wish to probe the temperature evolution of local structure, local anion/cation ordering, as well as the evolution of interstitial anions, which will provide insight into the anion transport pathways.

title: Compatibilization of poly (ethylene terephthalate)/ polypropylene blends via nanostructured silica aerogel

description: This file contains data as that obtained from theoretical and experimental characterization of synthesized silica aerogel particles and PP/PET binary blends. The specific surface areas and pore structure of hydrophilic and hydrophobic silica aerogel particles were determined using the Nitrogen adsorption analysis (Micromeritics -model TriStar II Plus) and Brunaure–Emmitt–Teller (BET) and Barrett–Joyner–Halendar (BJH) methods. The WAXS patterns for samples were performed using Asenware AW-DX 300 (XRD instrument). X-ray spectrometer was used Cu K_a radiation with a wavelength of 1.54 Å that operated at voltage 40 kV and current 30 mA. The data were obtained from 10 to 90 (2θ) at scan range of 0.05°∙min^(-1). The crystallite size was calculated using Debye-Scherrer analyze based on the following equation in X'Pert High Score Plus software. Rheometric Mechanical Spectrometer (RMS) instrument with parallel plate geometry, 25 mm plate diameter, and 1 mm gap (Physica MCR 501) was used to performing the dynamic rheological experiments on binary blends samples. The oscillatory tests in the linear viscoelastic region were done at a set frequency of 1 Hz and 0.3% strain. The frequency was swept from 0.1 to 100 rad∙s-1. All the measurements were accomplished at 270℃ under the nitrogen atmosphere. The storage and loss modulus data obtained from small-angle oscillatory shear (SAOS) experiments can be expressed as a function of relaxation time spectrum H(λ). The continuous relaxation time spectrum for the PP/PET/silica aerogel samples, which are extracted by Matlab software. The solid-like rheological behavior of the PP/PET filled samples can be described by five-parameter Fractional Zener Model (FZM). By fitting the dynamic modulus equation to the experimental data using the nonlinear least-square in Matlab software, the fitting parameters were obtained.
