Co‐Sensitized Solar Cell Achieves 13.7% Efficiency with Bis‐Hexylthiophene Dyes

Advanced Science, Volume 12, Issue 42, November 13, 2025.
The authors demonstrate that the longer excited state lifetime dye in combination with a copper electrolyte produces a high photovoltage of 1.22 V, owing to retarded interfacial charge recombination. The co‐sensitized solar cell achieves efficiencies of 13.7% under full sunlight and 29.7% under LED light.

Using accelerometer‐based behavioural classification to enhance scavenger conservation

Journal of Applied Ecology, Volume 62, Issue 11, Page 2987-3004, November 2025.
We provide a tool to help identify vulture feeding hotspots, supporting carcass management efforts to prevent poisoning. Integrated with near real‐time tracking, our model can support global efforts to combat scavenger poisoning. The training dataset, model and codes are provided in a user‐friendly platform, along with a conceptual framework, to ...

Skeleton‐Based Posture Recognition for Home Care From Virtual Unmanned Aerial Vehicle

Expert Systems, Volume 42, Issue 9, September 2025.
ABSTRACT This article presents a novel approach for real‐time posture recognition in monitoring scenarios, utilising a virtual camera simulated on a UAV within virtual environments. Leveraging the MediaPipe Pose library, key points of the body skeleton are extracted, focusing on a subset of 8 key points for computational efficiency.
