AGIcam: An open‐source Internet of Things–based camera system for automated in‐field phenotyping and yield prediction

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Continuous, high‐frequency monitoring is essential to capture rapid phenological transitions and dynamic crop responses to the environment. However, most phenotyping platforms lack the temporal resolution and automation required for consistent, season‐long trait assessment.

Comparative Study of Active Power Curtailment Methods of PVs for Preventing Overvoltage on Distribution Feeders

, 2018
© 2018 IEEE. Overvoltage is one of the major issues on distribution grids with high penetration of photovoltaic (PV) generation. Overvoltage could be prevented through the control of active/reactive power of PVs.

Multimethod Microstructural Diagnostics of Polymer Electrolyte Membrane Water Electrolysis Cell Components Uncovering Diverging Degradation Pathways After Short‐Term Testing

ChemElectroChem, Volume 13, Issue 12, 17 June 2026.
This study probes why polymer electrolyte membrane electrolyzers lose efficiency under different operating profiles. Using electrical tests, microscopy, and spectroscopy, Ti‐PTL passivation is established as the dominant cause for increased Ohmic resistance in samples aged under constant and triangular current profiles for 88 h.
