Engineered Au@CeO2 Hybrid Nanoparticles With Microenvironment Dependent Self‐Adjustability for Integration of Tumor‐Specific Photothermal‐Chemodynamic Therapy and Inflammation Prevention

Advanced Science, EarlyView.
An intelligent Au@CeO2 Hybrid Nanoparticles (ACEF) with microenvironment‐dependent self‐adjustability was engineered to not only perform efficient and tumor‐specific photothermal‐chemodynamic therapy for precise tumor elimination, but also serve as a ROS scavenger in healthy tissues around the tumor to avoid the unexpected oxidative damage and ...

Mesoporous Catalytic‐Adsorptive Nanoregulator Orchestrates Biofilm eDNA/LPS Disassembly and TLR9/TLR4 Immune Reprogramming to Resolve Diabetic Foot Infections

Advanced Science, EarlyView.
Chronic diabetic wounds are hindered by a “dual trap” of biofilm resistance and hyperinflammation. A mesoporous catalytic‐adsorptive nano‐regulator is developed to dismantle this barrier through simultaneous eDNA degradation and LPS sequestration. By silencing TLR4/9‐mediated signaling, the platform clears resilient pathogens and reprograms the immune ...

Therapeautic Cerium Oxide Nanoparticles

, 2021
The overall goal of the research project is to create a glass that produces cerium oxide nanoparticles and as an efficient delivery mechanism. Cerium is able to exist as Ce3+ and Ce4+ because it has two partially filled subshells. This coexistence allows

Molecular Design Strategies for High‐Voltage Organic Cathodes

Advanced Energy Materials, EarlyView.
This work proposes molecular engineering strategies for high‐voltage organic cathode materials for Li‐ion batteries: (1) increase Li‐O coordination number (CN), (2) achieve a greater increase in aromaticity upon reduction (∆Aromaticity), and (3) add an electron‐withdrawing group (EWG), through a combined experimental and computational study on reported
