Enantioselective Synthesis of Sulfinamidines via Asymmetric Rhodium–Catalyzed Imidation of Sulfenamides

ChemistryEurope, Volume 4, Issue 4, April 2026.
In this work, a catalytic enantioselective imidation approach is presented for the preparation of enantioenriched sulfinamidines from sulfenamides, employing a chiral dirhodium(II) tetracarboxylate catalyst. This method enables the imidation of N,N‐bisalkyl sulfenamides in yields of up to 98% and enantiomeric ratios up to 98:2, with a catalyst loading ...

Engineering Lipid Nanoparticles for Precision RNA Delivery: Design Principles, Targeting Strategies, and Clinical Prospects

Cancer Nexus, Volume 2, Issue 2, April 2026.
ABSTRACT Lipid nanoparticles (LNPs) represent the most clinically advanced platform for RNA delivery and have enabled major breakthroughs in vaccines and gene therapies. However, their broader application is still limited by inefficient extrahepatic delivery, immunogenicity, and insufficient control over tissue‐ and cell‐specific targeting. This review

Epistemic Uncertainty Analysis and Robust Optimization of a Second‐Generation Solvent‐Based Post‐Combustion Carbon Capture Process

Engineering Reports, Volume 8, Issue 4, April 2026.
Parametric uncertainty in the PZ/AFS post‐combustion carbon‐capture process model compromises the reliability of process designs extracted via traditional, deterministic optimization methods. We identify the twelve parameters exhibiting highest impact on capture and costs, and mitigate the design risk stemming from those via formulating and solving a ...

Lignin‐Derived Flame Retardants for Enhanced Fire Safety: A Review

Macromolecular Materials and Engineering, Volume 311, Issue 4, April 2026.
Lignin is a promising halogen‐free and bio‐based flame‐retardant component, where structure, plant origin, and extraction route govern its fire performance. While unmodified lignin promotes char formation, phosphorylation and P‐N/P‐Si functionalization can enhance its fire performance. Lignin‐based intumescent systems and nanostructures can reduce heat
