Perspective: Hollow Core Optical Fibres for Ultraviolet and Visible Wavelengths

open access: yesAdvanced Science, EarlyView.
Hollow core optical fibres bypass material constraints that limit optical fibres at ultraviolet and visible wavelengths. However, their challenging fabrication has limited their development, and significant gains in performance remain possible. In this perspective we outline approaches to enable the next generation of fibres for shorter wavelengths ...

Marcasite at the Permian‐Triassic Transition

open access: yesGeophysical Monograph Series, Page 377-399., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Impact of Processing Environment on Anti‐Solvent Free FAPbI3 Films and Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
This work explores the dependence of 2‐step FAPbI3 films and solar cells on the atmosphere and humidity during each processing step. In‐situ and ex‐situ characterizations are used to correlate film composition, structure, morphology, and intermediate phase evolution with solar cell performance and lifetime.

Effect of molecular anisotropy on the intensity and degree of polarization of light scattered from model atmospheres [PDF]

open access: yes
Computations of the intensity, flux, degree of polarization, and the positions of neutral points are presented for models of the terrestrial gaseous and hazy atmospheres by incorporating the molecular anisotropy due to air in the Rayleigh scattering ...

Decoherence due to elastic Rayleigh scattering

open access: yes, 2010
We present theoretical and experimental studies of the decoherence of hyperfine ground-state superpositions due to elastic Rayleigh scattering of light off-resonant with higher lying excited states.

2D velocity and temperature measurements in high speed flows based on spectrally resolved Rayleigh scattering [PDF]

open access: yes
The use of molecular Rayleigh scattering for measurements of gas velocity and temperature is evaluated. Molecular scattering avoids problems associated with the seeding required by conventional laser anemometry and particle image velocimetry.
