How Do SMEs Respond to Deglobalization? Insights from Italian SMEs in the Interwar Period (1936–1943)

Journal of Management Studies, EarlyView.
Abstract This study investigates how small and medium‐sized enterprises (SMEs) respond to deglobalization and economic nationalism, using historical evidence from fascist Italy, a period of autarky and restricted international trade. While prior research has focused primarily on larger firms, especially multinational enterprises (MNEs), the strategic ...

Solution ALD of (CH3NH3)(PbI3) Perovskite Thin Films Yields Functional Quality and Stability Superior to Classical Processing

Angewandte Chemie International Edition, Volume 65, Issue 3, 16 January 2026.
Chemically controlled deposition of the prototypical hybrid halide perovskite methylammonium triiodoplumbate(II), MAPI, is demonstrated in layer by layer fashion from the solution phase. Theoretical modeling confirms the accretion mechanism. Extensive materials and functional characterization highlight how chemical control of nucleation and growth ...
