Integrating Visible‐Light Photocatalysis and Enzymes for the Stereoselective Synthesis of Alcohols and Amines

Advanced Synthesis &Catalysis, EarlyView.
The integration between visible‐light photocatalysis and biocatalysis has the potential to greatly improve modern organic synthesis by combining the production of valuable synthetic intermediates under mild photochemical conditions with the high degree of stereoselectivity reached by enzymes. The review collects the recent efforts in the photoenzymatic

Molten‐Salt‐Mediated Synthesis of Atomic Manganese/Cobalt Catalysts on Bioceramic Microparticles for Catalytic Anti‐Osteoarthritis Treatments

Advanced Science, EarlyView.
Microparticle‐based antioxidants capable of scavenging multiple reactive oxygen species (ROS) have been developed. When retained within the articular cavity of osteoarthritic mice, Mn‐ or Co‐AKT‐MPs protect the inherent homeostasis between cartilage anabolism and catabolism, and inhibit synovial inflammation.

Bionic Multimodal Augmented Somatosensory Receptor Enabled by Thermogalvanic Hydrogel

Advanced Science, EarlyView.
A skin‐inspired self‐powered multimodal fingertip receptor that integrates thermogalvanic hydrogels as active mechanoreceptors and thermoreceptors is proposed. By exploiting dynamic‐static thermovoltage of the hydrogel to visualize the unsteady interfacial heat conduction, different materials can be determined in 80 ms.

Engineered Anti‐Senescence Trachea With Post‐Transplanted Regenerative Homeostasis

Advanced Science, EarlyView.
Bioengineered trachea undergoes post‐transplanted senescence, which is found in this study for the first time. Hebe‐ET is designed with dual anti‐senescence strategies: fiber‐film scaffold in cartilage rings for close‐packed cell interaction, and quercetin‐loaded fibrous rings for immune modulation.

Quantitative analysis of bone reactions to relative motions at implant-bone interfaces [PDF]

, 1993
Connective soft tissues at the interface between implants and bone, such as in human joint replacements, can endanger the stability of the implant fixation. The potential of an implant to generate interface bone resorption and form soft tissue depends on
