Mineralized Cryogel/Hydrogel Constructs to Recapitulate Early Breast Cancer Bone Metastasis In Vitro

open access: yesAdvanced Science, EarlyView.
A new biphasic in vitro cryogel/hydrogel model of early breast cancer bone metastasis provides precise control over microenvironmental cues and microscopic access to the spatiotemporal cancer cell distribution. Deposited bone‐like mineral is observed to strongly impede the effects of biomolecular signals, as evidenced by both colonization profiles and ...

Energy‐Enhanced Aqueous Organic Flow Batteries Enabled by Integrated Proton‐Coupled Electron Transfer‐Induced Carbon Capture and Utilization

open access: yesAdvanced Energy Materials, EarlyView.
This work presents an aqueous organic flow battery that integrates energy storage with carbon capture and utilization. By feeding flue gas into an oxygen‐tolerant FFDS posolyte, reversible CO2 capture, utilization, and release is achieved via PCET‐driven pH swings.

Promoting H2O2 production via 2-electron oxygen reduction by coordinating partially oxidized Pd with defect carbon. [PDF]

open access: yes, 2020
Electrochemical synthesis of H2O2 through a selective two-electron (2e-) oxygen reduction reaction (ORR) is an attractive alternative to the industrial anthraquinone oxidation method, as it allows decentralized H2O2 production. Herein, we report that the
