The Bull-James assembly
Chiral molecules are widely used in many fields of research and so practically simple, accurate methods to measure their enantiopurities are required. This review's initial focus is on one such method, the Bull-James...

Order reconstruction patterns in nematic liquid crystal wells
We numerically study structural transitions inside shallow sub-micrometre scale wells with square cross section, filled with nematic liquid crystal material. We model the wells within the Landau–de Gennes theory. We obtain two...

Research priorities in mesothelioma
RJ Stephens, C Whiting, K Cowan, James Lind Alliance Mesothelioma Priority Setting Partnership Steering Committee
Aug 17, 2021
BACKGROUND: In the UK, despite the import and use of all forms of asbestos being banned more than 15 years ago, the incidence of mesothelioma continues to rise. Mesothelioma is almost invariably fatal, and more research is...
Inversion asymmetry effects in modulation-doped Cd1-xMnxTe quantum wells
Caitlin Rice, D Wolverson, A Moskalenko, S J Bending, Gregorsz Karczewski, Tomek Wojtowicz
Mar 25, 2013
We report a striking in-plane anisotropy of the spin-flip Raman signals observed for dilute magnetic Cd1-xMnxTe quantum wells containing a two-dimensional electron gas. The effect depends upon electron concentration, which can...

Photoluminescence efficiency of zincblende InGaN/GaN quantum wells
SA Church, M Quinn, K Cooley-Greene, B Ding, A Gundimeda, MJ Kappers, M Frentrup, DJ Wallis, RA Oliver, DJ Binks
May 10, 2021
Growing green and amber emitting InGaN/GaN quantum wells in the zincblende, rather than the wurtzite, crystal phase has the potential to improve efficiency. However, optimization of the emission efficiency of these...

This essay discusses James’s prefaces to the New York Edition as instances of the development of the form of the preface for James’s critical purposes. In particular, it focuses on the deployment of James’s frequent and...
Exchange interactions in Cd1-xMnxTe wide quantum wells
C. Rice, L. C. Smith, J. J. Davies, D. Wolverson, M. Wiater, G. Karczewski, T. Wojtowicz
Oct 24, 2012
The exchange interactions between excitons and manganese ions in wide (80 nm) quantum wells of Cd1−xMnxTe (x≈0.0015 and x≈0.00027) have been measured for states with center of mass quantum numbers up to 10. The corresponding...

Real-Time Observation of Exciton-Phonon Coupling Dynamics in Self-Assembled Hybrid Perovskite Quantum Wells
L Ni, U Huynh, A Cheminal, T Thomas, R Shivanna, T Hinrichsen, S Ahmad, A Sadhanala, A Rao
Sep 14, 2018
Self-assembled hybrid perovskite quantum wells have attracted attention due to their tunable emission properties, ease of fabrication and device integration. However, the dynamics of excitons in these materials, especially how...
