A Homobimetallic Frustrated Lewis Pair Cobalt Catalyst for the Methanolysis of Hydrosilanes

open access: yesAngewandte Chemie International Edition, Accepted Article.
The bimetallic Co(I)/Co(–I) complex [Co(CO)2(κ3‐P,N,P‐PNHP)][Co(CO)4] (1) has shown excellent activities in the methanolysis of hydrosilanes, surpassing the related bimetallic Co(I)/Co(–I) complex [Co(CO)(PMe2Ph)(κ3‐P,N,P‐PNHP)][Co(CO)4] (2), the Co(II) complex [Co(Cl)2(κ3‐P,N,P‐PNHP)] (3), and the Co(I) complex [Co(CO)2(κ3‐P,N,P‐PNHP)]Cl (4).

Influence of Thermoplastic Polyurethane Content on Interlaminar Adhesion of Hot‐Pressed Aramid Fabrics

open access: yesJournal of Applied Polymer Science, EarlyView.
Optimized hot‐pressing conditions (200°C, 10 MPa, 25 min) were identified using a DOE approach. Two TPU layers (29.9 wt%) achieved the best interlaminar adhesion, yielding a 67% increase in T‐peel strength. Dynamic mechanical analysis revealed lower activation energy at optimal composition, indicating improved fiber‐matrix interaction.

Chitosan Hydrogels Crosslinked With Glutaraldehyde for Potential Toxic Elements Removal: Batch and Purification Device Analysis

open access: yesJournal of Applied Polymer Science, EarlyView.
ABSTRACT The presence of toxic metal ions in contaminated wastewater raises significant concerns for human health. Three‐dimensional porous systems like hydrogels are being explored for contaminant removal. Still, there is a lack of understanding of their production parameters and performance.

Axion‐Like Interactions and CFT in Topological Matter, Anomaly Sum Rules and the Faraday Effect

open access: yesAdvanced Physics Research, Volume 4, Issue 7, July 2025.
This review investigates the connection between chiral anomalies and their manifestation in topological materials, using both perturbative methods based on ordinary quantum field theory and conformal field theory (CFT). It emphasizes the role of CFT in momentum space for parity‐odd correlation functions, and their reconstruction by the inclusion of a ...
