Abstract: The use of pulsed mode scanning electron microscopy cathodoluminescence (CL) for both hyperspectral mapping and time-resolved measurements is found to be useful for the study of hybrid perovskite films, a class of...
Distal Bias of Meiotic Crossovers in Hexaploid Bread Wheat Reflects Spatio-Temporal Asymmetry of the Meiotic Program.
Kim Osman, Uthman Algopishi, James D Higgins, Ian R Henderson, Keith J Edwards, F Chris H Franklin, Eugenio Sanchez-Moran
Feb 26, 2021
Meiotic recombination generates genetic variation and provides physical links between homologous chromosomes (crossovers) essential for accurate segregation. In cereals the distribution of crossovers, cytologically evident as...

This module reflected work within the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) to develop and validate composite disease activity measures in psoriatic arthritis (PsA). At the Outcome...
Formation of Cu3BiS3 thin films via sulfurization of Bi-Cu metal precursors
Diego Colombara, Laurence M Peter, K Hutchings, K D Rogers, S Schäfer, Jesse T R Dufton, M Saiful Islam
Jun 01, 2012
Thin films of Cu 3BiS 3 have been produced by conversion of stacked and co-electroplated Bi-Cu metal precursors in the presence of elemental sulfur vapor. The roles of sulfurization temperature and heating rate in achieving...
Picosecond and nanosecond pulse delivery through a hollow-core Negative Curvature Fiber for micro-machining applications
Piotr Jaworski, Fei Yu, Robert R.J. Maier, William J. Wadsworth, Jonathan C. Knight, Jonathan D. Shephard, Duncan P. Hand
Sep 23, 2013
We present high average power picosecond and nanosecond pulse delivery at 1030 nm and 1064 nm wavelengths respectively through a novel hollow-core Negative Curvature Fiber (NCF) for high-precision micro-machining applications....
Structure of plasmonic aerogel and the breakdown of the effective medium approximation
A method for making aerogel doped with gold nanoparticles (GNPs) produces a composite material with a well-defined localized surface plasmon resonance peak at 520 nm. The width of the extinction feature indicates the GNPs are...
Double spin resonance in a spatially periodic magnetic field with zero average
Alain Nogaret, F Nasirpouri, J-C Portal, H E Beere, D A Ritchie, A T Hindmarch, C H Marrows
Apr 01, 2011
We report on the electrical detection of spin resonance in a two-dimensional electron system modulated by a periodic magnetic field with zero average. Spin degeneracy is lifted by a large magnetic field applied in the plane...
The F-box protein Cdc4/Fbxw7 is a novel regulator of neural crest development in Xenopus laevis.
Alexandra D Almeida, Helen M Wise, Christopher J Hindley, Michael K Slevin, Rebecca S Hartley, Anna Philpott
Jun 13, 2011
BACKGROUND: The neural crest is a unique population of cells that arise in the vertebrate ectoderm at the neural plate border after which they migrate extensively throughout the embryo, giving rise to a wide range of...

Development of a prototype wound dressing technology which can detect and report colonization by pathogenic bacteria
Jin Zhou, Thet Naing Tun, Sung-Ha Hong, June D Mercer-Chalmers, Maisem Laabei, Amber E R Young, A Tobias A Jenkins
Dec 15, 2011
A new methodology for detecting the microbiological state of a wound dressing in terms of its colonization with pathogenic bacteria such as Staphylococcus aureus or Pseudomonas aeruginosa has been developed. Here we report how...
Observation of bright solitons in a semiconductor microcavity
M Sich, D N Krizhanovskii, M S Slolnick, Andriy V Gorbach, Robin Hartley, Dmitry V Skryabin, E A Cerda-Mendez, K Biermann, R Hey, P V Santos
Jan 01, 2012
Microcavity polaritons are composite half-light half-matter quasiparticles, which have recently been demonstrated to exhibit rich physical properties, such as non-equilibrium condensation, parametric scattering and superfluidity....
Getting new staff to stay
Newcomer turnover is a major cost to organizations, and the quality of new employees' experiences in the first few months is critical in determining whether they decide to stay or leave. In a study that focused on the first...
Computational mutagenesis reveals the role of active-site tyrosine in stabilising a boat conformation for the substrate
Molecular dynamics simulations have been performed for non-covalent complexes of phenyl beta-xylobioside with the retaining endo-beta-1,4-xylanase from B. circulans (BCX) and its Tyr69Phe mutant using a hybrid QM/MM methodology....
Transannular, decarboxylative Claisen rearrangement reactions for the synthesis of sulfur-substituted vinylcyclopropanes
Unsaturated epsilon-lactones bearing an alpha-arylsulfonyl or alpha-arylsulfoximinyl substituent undergo stereoselective transannular, decarboxylative Claisen rearrangement to give substituted vinylcyclopropanes.
