Thermo‐Optically Tunable Mid‐Infrared Bandpass Filters Comprising Ultra‐Thin Silicon‐on‐Sapphire Metasurfaces

open access: yesLaser &Photonics Reviews, EarlyView.
Ultra‐thin, tunable bandpass filters are a pathway to realizing mid‐infrared spectrometers that are compact, low power, and performant. The authors elicit 141 nanometres of passband tunability in the mid‐infrared in silicon on sapphire zero‐contrast gratings by exploiting silicon's high thermo‐optic coefficient.

Easy‐to‐use B1+ shims for human brain imaging at 7 T

open access: yesMagnetic Resonance in Medicine, EarlyView.
Abstract Purpose B1+$$ {B}_1^{+} $$ field inhomogeneity is a common problem in high field brain MRI (>3$$ >3 $$ T). Parallel‐transmit methods that adjust the B1+$$ {B}_1^{+} $$ field channelwise often require valuable scan time. Group‐optimized phase shims are presented to increase or attenuate the B1+$$ {B}_1^{+} $$ field in specific brain regions ...

Empirical research review on Solastalgia: Place, people and policy pathways for addressing environmental distress

open access: yesPeople and Nature, EarlyView.
Abstract The growing impacts of climate change and environmental degradation have heightened concerns about human emotional and psychological well‐being, particularly regarding place loss and environmental changes. Solastalgia, defined as distress from environmental change while in one's ‘home’ environment, is an emerging concept for assessing loss and
