Drag as a meaningful occupation: A scoping review
Australian Occupational Therapy Journal, Volume 73, Issue 3, June 2026.Abstract Introduction Drag is a form of entertainment in which performers caricature or challenge gender norms. It is increasingly present in the media and research and seems to involve multiple interrelated activities. The objective of this study was to explore the scope of empirical research regarding the experience of drag performers and its ...

Synthesis of Hydrocarbon Fuels From Dimethyl Ether Through Co‐Oligomerization of Olefins
Chemie Ingenieur Technik, Volume 98, Issue 5, Page 262-270, May 2026.This work investigates the impact of higher olefins and typical impurities from a preceding Dimethyl ether‐to‐Olefins (DtO) process on olefin oligomerization for sustainable fuel production. Several key properties of the kerosene fraction comply with the ASTM D7566 22a standard for sustainable aviation fuels, whereas some important properties of the ...

Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications
Mass Spectrometry Reviews, Volume 45, Issue 3, Page 548-582, May/June 2026.ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).
