Thermo‐Optical Analysis of Surface‐ and Volume‐Additivated Polymer Powders for Near‐Infrared Laser Powder Bed Fusion

open access: yesAdvanced Photonics Research, EarlyView.
Precipitated PA11 powders for laser powder bed fusion are additivated with small amounts of carbon black nanoparticles on and in the particles. The position of the nanoparticles has a strong impact on dispersion, crystallization, and thermal oxidation.

Development of Photo‐Biocatalytic Redox System for Asymmetric Synthesis of Optically Active Amines Using Blue Light and Transaminases. A Case Study Toward Mavacamten

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Abstract α‐Chiral amines are versatile building blocks for the asymmetric synthesis of optically pure high‐added‐value chemicals, including pharmaceuticals, agrochemicals, and natural products. Herein, we report a one‐pot, two‐step sequential deracemization of racemic sec‐alcohols to optically enriched primary amines throught a photo‐biocatalytic ...

Facile Functionalization of Separator with an Amino Acid to Boost Li–S Battery Performance

open access: yesAdvanced Sustainable Systems, EarlyView.
This study introduces a viable bio‐approach to functionalize conventional separators using leucine‐polyacrylic acid (Leu‐PAA) via the simple soaking method. This strategy synergistically improves polysulfide trapping, regulates lithium‐ion flux, and enhances thermal and mechanical stability, leading to excellent cycling stability.
