A General Workflow for Tangential Flow Filtration Perfusion Scale‐Up

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Tangential flow filtration (TFF) perfusion using hollow‐fiber modules offers substantial advantages over other mammalian cell retention technologies. Recently, increased awareness of Starling flow has helped to enhance filtration performance to similar, or even higher levels compared to alternative technologies.

High‐performance tetrahedral palladium nanocatalyst for microwave‐assisted organic synthesis

Bulletin of the Korean Chemical Society, EarlyView.
Tetrahedral palladium nanoparticles anchored on graphene sheets (T‐Pd/graphene) were synthesized through a solvent‐free process involving thermal decomposition in an environment rich in carbon monoxide at elevated temperatures and have high catalytic activity for organic chemistry reactions. Abstract Palladium is widely recognized for its effectiveness

Carrier‐free self‐assembled nanomedicine for combination‐therapy of acute myeloid leukemia

BMEMat, EarlyView.
CPDS combines drugs with three different mechanisms of action to achieve a multi‐mechanism combination therapy for AML by directly killing tumor cells and activating anti‐tumor immunity. Abstract As the main acute myeloid leukemia (AML) clinical treatment, the chemotherapy alone cannot meet the clinical therapeutic needs due to the high heterogeneity ...
