Directional Second Sphere Effect on CO2 Activation and Reduction by Iron Porphyrin in Aprotic and Protic Media

Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.
Directional control within the secondary coordination sphere redefines CO2 reduction by iron porphyrins. Simply rearranging identical urea hydrogen‐bond donors modulates reactivity, revealing that optimal catalysis does not only arise from maximal intermediate stabilization, but also from directional, adaptive non‐covalent interactions that balance ...

Measuring Interactional Competence in a Japanese University EFL Speaking Context

International Journal of Applied Linguistics, EarlyView.
ABSTRACT The ability to interact is an integral aspect of speaking proficiency. Therefore, methods of assessing interaction need to be incorporated into second language (L2) speaking tests. The main purpose of this exploratory study is to attempt to quantify interactional competence (IC) in a Japanese university EFL (English as a foreign language ...

Changed Minds and L2 Motivation: Reflections of Japanese EFL Students Living, Laboring and Learning in Vietnam

International Journal of Applied Linguistics, EarlyView.
ABSTRACT English as a lingua franca (ELF) is increasingly used for communication in many EFL contexts, including Vietnam. Although Japan and Vietnam have a long history of economic cooperation, for practical reasons, English typically functions as the medium of communication between the two groups. This study examines Japanese expats who had studied or
