Simple (YGa)2O3/F‐SnO2 Heterojunction‐Based Solar‐Blind Ultraviolet Photodetector Operable in Two Modes With Superb Performance

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Yttrium doping was proposed to expand the bandgap and inhibit the oxygen vacancies of Ga2O3 to form (YGa)2O3 alloy with reduced background carriers and trap centers. Beneficially, simple vertical‐structured (YGa)2O3/FTO heterojunction photodetectors exhibit superb performance with particularly low dark current and fast photoresponse in both self‐driven

A Scoping Review and Bibliometric Analysis on Smart Firefighting in Buildings and Infrastructures

Fire and Materials, EarlyView.
ABSTRACT Smart Firefighting is a concept that has emerged within the fire engineering and fire science disciplines in recent years. It can enable informed decision making and improved fire safety. However, its scope, definition, outcomes, and value to emergency management remain unclear. To investigate this, a scoping review and a bibliometric analysis
