Influence of TiC and TiN Ceramic Reinforcements on the Microstructure, Thermal Expansion Behavior, and Tensile Properties of Invar 36 Manufactured by Laser Powder Bed Fusion

Advanced Engineering Materials, Volume 28, Issue 21, 4 November 2026.
This study examines Invar composites reinforced with titanium carbide (TiC) and titanium nitride (TiN) using laser powder bed fusion (LPBF). It presents the influence of reinforcements on microstructure, tensile properties, and thermal expansion. Results show that TiC effectively strengthens Invar while maintaining low thermal expansion, whereas TiN ...

Regioselective Diversification of Aminopyrazoles via Ir‐Catalyzed C─H Borylation

Advanced Synthesis &Catalysis, Volume 368, Issue 21, 3 November 2026.
Aminopyrazoles, an important bioactive pharmacophore, are typically accessed inefficiently through de novo syntheses that yield isomeric mixtures of 3‐ and 5‐substituted derivatives. To address this challenge, we have elaborated readily available 3‐ and 5‐aminopyrazole fragments using Ir C─H borylation, regioselectively furnishing boronates for ...

Multienzyme Cascade Reactions: Compatibility, Cooperativity, and Control

Advanced Synthesis &Catalysis, Volume 368, Issue 21, 3 November 2026.
Multienzyme cascade reactions are sequences of telescoped biotransformations that avoid the isolation of intermediates and offer significant efficiency advantages over traditional multistep routes. This review article highlights recent examples of multienzyme cascades and explores how their success depends on the consideration of compatibility ...
