Altitude Effects on Ejected Flames in Façade Calibration Tests: Experimental and Numerical Investigation

open access: yesFire and Materials, Volume 49, Issue 8, Page 1189-1204, December 2025.
ABSTRACT Ejected flames from a compartment opening pose a significant fire hazard to building fire safety, serving as a trigger of rapid façade flame spread. Although extensively studied under standard altitude conditions, their fire behavior under subatmospheric pressure remains to be further explored.

Low Levels of Zinc Exchanged into Cu‐SSZ‐13 Increase Methanol Production in the Partial Oxidation of Methane to Methanol

open access: yesChemistryOpen, Volume 14, Issue 12, December 2025.
A little zinc helps! The addition of small quantities of zinc to Cu‐SSZ‐13 leads to a significant enhancement in methanol production in the partial oxidation of methane to methanol. Cu‐SSZ‐13 is currently used industrially for the selective catalytic reduction of nitric oxides and has shown potential for the direct oxidation of methane to methanol ...

Health Risks of Atmospheric Fine Particulate Matter (PM2.5) and Its Trace Elements in Mabopane, South Africa

open access: yesEnvironmental Quality Management, Volume 35, Issue 2, Winter 2025.
ABSTRACT Atmospheric fine particulate matter (PM2.5) contributes to approximately 4 million premature deaths globally each year. This study aimed to investigate the health risks of atmospheric PM2.5 and its trace elements in Mabopane, South Africa. PM2.5 samples were collected every sixth day from June 15, 2022 to February 28, 2023 using a GilAir‐5 ...

Ghosting at the border: the racialization of extraterritoriality at the US Supreme Court Les limbes de la frontière : racialisation de l'extraterritorialité par la Cour suprême des États‐Unis

open access: yesJournal of the Royal Anthropological Institute, Volume 31, Issue 4, Page 1116-1135, December 2025.
The theoretical association of an inclusive public sphere with liberal democratic governing begs a closer examination. This article pursues forms of disqualification implicit in the idea of political community as a national project, ultimately finding that the exclusion of foreigners does not begin on the far side of the US border, but well within it ...

Biological invasions: a global assessment of geographic distributions, long‐term trends, and data gaps

open access: yesBiological Reviews, Volume 100, Issue 6, Page 2542-2583, December 2025.
ABSTRACT Biological invasions are one of the major drivers of biodiversity decline and have been shown to have far‐reaching consequences for society and the economy. Preventing the introduction and spread of alien species represents the most effective solution to reducing their impacts on nature and human well‐being.
