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

open access: yesFire and Materials, Volume 50, Issue 2, Page 145-173, March 2026.
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

Lightning‐caused disturbance frequency and severity varies with topography in an Afromontane forest

open access: yesJournal of Ecology, Volume 114, Issue 3, March 2026.
The results indicate that lightning disturbance severity differs within and among sites, potentially mediated by differences in lightning tolerance among tree species, and provide preliminary support for the hypothesis that disturbance severity declines with disturbance frequency. Abstract Lightning is an important agent of tropical tree mortality, but

Spectral Characteristics and Evolution Mechanism of Silicon Rubber Surface Discharge Under Thermal Ageing Condition

open access: yesHigh Voltage, Volume 11, Issue 1, Page 192-200, February 2026.
ABSTRACT Surface discharge is a typical fault type in electric power equipment. High temperature in long‐term operation can easily lead to ageing of materials, resulting in changes in surface characteristics and surface discharge faults. In this paper, a method of surface discharge identification of silicon rubber (SiR) based on spectral detection ...
