Main Group Metals in Redox Catalysis
European Journal of Inorganic Chemistry, EarlyView.Main group metal redox catalysis is emerging as a credible alternative to transition metal chemistry. Elements from groups 13 to 15 now enable diverse catalytic manifolds, driven by ligand design and control of electronic structure. This review highlights recent advances, key design principles, and remaining challenges, positioning main group metals as

Supported ammonia borane decomposition through enhanced homopolar B–B coupling
, 2018 The thermolytic decomposition of ammonia borane (AB) is known to proceed through the polymeric coupling reaction between –BH3 and –NH3 sites of multiple ammonia borane molecules, which results in the release of hydrogen and other by-products, e.g ...

Ammonia Borane: An Extensively Studied, Though Not Yet Implemented, Hydrogen Carrier
Energies, 2020 Ammonia borane H3N−BH3 (AB) was re-discovered, in the 2000s, to play an important role in the developing hydrogen economy, but it has seemingly failed; at best it has lagged behind.

Synthesis of Amorphous‐Crystalline Mixture Boron Nitride for Balanced Resistive Switching Operation
Small, EarlyView.An amorphous–crystalline mixture BN (acm‐BN) is synthesized through low‐pressure chemical vapor deposition, achieving balanced resistive switching with low SET voltage and stable RESET. High‐resolution transmission electron microscopy reveals that BN films are fully amorphous at 930 °C, a mixed amorphous–crystalline phase is achieved at 990 °C.

Role of Pressure in the Growth of Hexagonal Boron Nitride Thin Films from Ammonia-Borane
, 2016 We analyze the optical, chemical, and electrical properties of chemical vapor deposition (CVD) grown hexagonal boron nitride (h-BN) using the precursor ammonia-borane (H3N–BH3) as a function of Ar/H2 background pressure (PTOT).
