Low Noise and Drift Reconfigurable Solution‐Processed Chalcogenide Phase Change Metasurfaces

open access: yesSmall Methods, EarlyView.
Chalcogenide glasses, favored in reconfigurable optoelectronics, rely on costly ultra‐high vacuum‐based PVD methods. A cost‐effective, solution‐based approach to synthesize these materials, producing high‐quality antimony sulfide films with comparable phase change performance are introduced.

Seasonal excess: Moving with place and produce through creative fieldwork

open access: yesGeographical Research, EarlyView.
In this visual essay, we explore place‐based and creative approaches towards excess seasonal produce. We foreground the situated, place‐based, and rural perspectives towards farming, food waste, and notions of excess. We use reflections of creative fieldwork activities to bring into dialogue notions of coloniality, belonging, and rural livelihoods ...

Multi‐Module Micro/Nanorobots for Biomedical and Environmental Remediation Applications

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 7, July 2025.
Multi‐module microrobots (MNRs) have overcome the limitations of single‐module systems by integrating components such as propeller, actuator, manipulator, and imaging modalities. They show promise in biomedical applications, such as targeted drug delivery and tissue repair, as well as in environmental remediation, including pollutant removal.

Capturing Extraction: Geology, Photography, Industry and Institutional History in the Bingley Archive

open access: yesBulletin of Latin American Research, Volume 44, Issue 3, Page 198-219, July 2025.
Godfrey Bingley was a British industrialist who took up geology, photography and travel in the 1880s. His photographs are housed at the University of Leeds, where he worked with its Chair of Geology. This article analyses the archive's projection of the imperial geological imaginary that emanated from Britain and extended to the Americas.
