Spin-echo encoded neutron refraction of air bubbles in a fibrous protein gel

Dr Wim Bouwman, Miss Zhaojun Wang, Dr Atze Jan Van Der Goot, Miss Bei Tian, Mr Evgenii Velichko & Dr Robert Dalgliesh
Calcium caseinate is a promising candidate to be developed into a meat analogue. When the dough like protein gel is subjected to mild shear and heat, it turned into a pronounced fibrous structure with lots of air bubbles entrapped in it. Plenty of effort has been spent to characterise the fibres, it was not until recent that the role of air bubbles are being noticed. These air bubbles are prolate spheroid like, with the long...

Interphase load partitioning during deformation of Ni-Cr-Al-Ti-Mo alloys

Dr Howard Stone, Mr James Moffat, Mr Robert Thompson, Mr Thomas Edwards, Dr Lewis Owen, Dr Katerina Christofidou, Ms Amy Goodfellow, Dr Nick Jones & Dr Joe Kelleher
In this study, in-situ tensile testing will be used to determine the degree of load partitioning that occurs between the gamma and gamma prime phases in a series of model Ni-based superalloys with varying Mo content at room temperature and at 700C. These data will be compared with predictions of the strengthening contributions of these alloys to quantify and separate the effect of coherency strains on alloy strength. Such insights will be invaluable in understanding...

Investigation of complex magnetic structure and the role of frustration using neutron diffraction study in CeRh1-xPdxSn

Dr Devashi Adroja, Mr CHONGLI YANG, Professor Toshiro Takabatake, Dr Amitava Bhattacharyya & Professor David Keen
The quasi-kagome Kondo lattice CeRhSn exhibits intrinsic quantum criticality induced by geometrical frustration. Divergent Grüneisen ratios provide evidence for a zero-field QCP. The anisotropy of thermal expansion, which only displays quantum critical behavior along a-axis and not along the c-axis, indicates that geometrical frustration drives quantum criticality in this system.. Our recent study of CeRh1-xPdxSn series reveals magnetic transitions for x ≥ 0.4. The spin-flop behaviour in the magnetization curve supports the AFM ordered state....

Analysing intermediates of a CO2 insertion reaction using simultaneous operando INS and Raman measurements.

Professor Robert Raja, Mr Jack Parsons & Dr Stewart Parker
Atmospheric levels of CO2 are increasing at uncontrolled levels and as such methods of CO2 utilisation are being researched. A key reaction for this purpose is the coupling of CO2 with epoxides to form cyclic carbonates. The authors have shown that silica supported imidazolium halides are highly active catalysts for this reaction. The literature shows that hydrogen bonding to the epoxide helps initiate the reaction and we believe that the silanols on the silica surface...

Measuring Radiation Effects on COTS Devices and Sensors

Professor Klaus McDonald-Maier, Dr SANGEET SAHA, Dr Chris Frost, Ms ZEBA KHANAM & Dr Bilal Aslam
Performance degradation analysis of the sensors and embedded computing systems in the radiation-rich environment is a research area for nuclear robotics. In this perspective, a couple of experiments are proposed to capture the neutron-induced noise on the Raspberry Pi camera, Kinect camera, and ZYNQ FPGA. The experiments are designed to maintain a log of the data from the irradiated devices to a wide neutron fluence range. The captured data will be useful in modelling the...

High precision measurements of the spin wave dispersion in Yttrium Iron Garnet

Dr Andrew Princep, Dr Russell Ewings, Dr Alexy Karenowska & Professor Andrew Boothroyd
Yttrium Iron Garnet (YIG) is a material with extremely wide ranging applications, having the narrowest ferromagnetic resonance linewidth of any known material. Despite decades of experiments on this material, data relating to its full magnon spectrum is sparse. The spectrum is known to contain 20 branches, but the most thorough work to date relies upon a 3-parameter hamiltonian derived from fitting just 3 (the only 3 that were observed in what is still the only...

Effect of Variation in Initial Crystallographic Texture of Aluminum Alloys on Residual Stress Stability in Fatigue Loading

Mr Muhammad Kashif Khan, Professor Michael Fitzpatrick, Mr Sunil Anandatheertha & Dr Winfried Kockelmann
Laser Shock Peening (LSP) improves the fatigue properties of new and damaged metallic components by introducing beneficial compressive stresses. The residual stress field that develop in the material after LSP and its behaviour in the service life depends on the microstructure and elastic-plastic properties of the material. The engineering components with variable microstructure and crystallographic texture when treated with LSP develop different residual stresses. In this experiment, we will underpin the deformation mechanism of aerospace...

Probing the ground state magnetic structure of single crystalline Mn2V2O7

Dr Jhuma Sannigrahi, Dr Silvia Capelli, Dr Matthias Gutmann, Dr Zhangzhen He, Dr Devashi Adroja, Professor Subham Majumdar & Dr Robin Perry
Mn2V2O7 exhibits reversible structural transition from the high temperature monoclinic phase (C2/m) to low temperature triclinic phase (P-1) near room temperature where Mn2+ ions form regular and distorted honeycomb network respectively. An antiferromagnetic like transition below 20 K as well as magnetic anisotropy were observed in this compound. We performed powder neutron diffraction measurement and this data fitted well with commensurate propagation vector (0,0.5,0) between 12 K and TN =20 K and Mn2+ shows the...
