Photocatalytic Lignin Depolymerization and Cross‐Coupling With Alcohols to Produce Unsymmetric Aromatic Diols

Angewandte Chemie, EarlyView.
A photocatalytic approach for efficient one‐pot direct lignin depolymerization and subsequent cross‐coupling with alcohols for the production of unsymmetrical aromatic diols has been demonstrated. ABSTRACT Conversion of lignin into chemical products typically involves two separate steps, such as depolymerization and subsequent upgrading of monomers ...

Base-catalyzed oxidative depolymerization of softwood kraft lignin

Industrial Crops and Products, 2020
Abstract Lignin is an important aromatic biopolymer with the structure based on phenolic units. Depolymerized lignin materials can be useful substitutes for phenol in phenol-formaldehyde resins. Our aim was to examine the potential of the base-catalyzed oxidation method to provide reactive oligomeric lignin fragments from softwood kraft lignin ...

A Wireless 3D Magneto‐Mechanical Stimulation Platform Drives In Situ Chondrogenic Commitment of Endogenous MSCs

Advanced Science, EarlyView.
An intracellular magneto‐mechanical platform utilizing MSC‐targeted nanomotors is developed. After intra‐articular delivery, these nanomotors target endogenous BMSCs and are actuated within lysosomes to execute trans‐planar rotational‐bouncing motions under a rotating‐fluctuating 3D magnetic field, generating amplified mechanical stimulation.

Ordered Pt3Mn Intermetallic Nanoparticles Supported on Atomically Dispersed Mn–N–C as Electrocatalysts for Fuel Cells

Angewandte Chemie, EarlyView.
Ordered L12‐Pt3Mn intermetallic alloys are uniformly deposited onto atomically dispersed Mn–N–C supports. The synergistic effect between MnN4 sites and Pt3Mn elevates interfacial binding strength and dissolution barriers while favorably weakening *OH adsorption. It delivers exceptional catalytic activity and stability in fuel cells, serving as an ideal

Reductive–Oxidative Tandem Catalysis for Lignin Depolymerization to Benzoquinones and Benzaldehydes

ChemSusChem
This study investigates a tandem Pd‐catalyzed reductive depolymerization of lignin and subsequent Co(salen)‐catalyzed oxidative cleavage to obtain benzoquinones and benzaldehydes. The reductive depolymerization will result in lignin macromolecules with heavily increased phenolic OH content, which are then selectively cleaved by the Co(salen) catalyst ...
