Breaking Barriers: Scaffolding Social‐Symbolic Work for Women’s Economic Empowerment

open access: yesJournal of Management Studies, EarlyView.
Abstract This study advances the understanding of Women’s Economic Empowerment (WEE) in non‐Western contexts by theorizing how social‐symbolic work facilitates empowerment despite entrenched institutional and cultural constraints. Drawing on a qualitative study into the establishment of Kuwait’s first women’s business incubator, we explore how female ...

Band Gap Tuneability in Antiperovskite‐Based Nitrides AE3PnN and Imides AE5Pn2(NH)2 (AE = Ca, Sr; Pn = As, Sb, Bi)

open access: yesAngewandte Chemie, Volume 138, Issue 20, 11 May 2026.
A series of imide‐based defect antiperovskites AE5Pn2(NH)2 (AE = Ca, Sr; Pn = As, Sb, Bi) has been synthesized using the ammonothermal method. DFT calculations and spectroscopy revealed direct band gaps suitable for photovoltaic absorber materials. The discovered compounds can further be used as precursors for the synthesis of AE3PnN antiperovskites as
