Block-copolymer-assisted synthesis of hydroxyapatite nanoparticles with high surface area and uniform size

open access: yes, 2011
We report the synthesis of hydroxyapatite nanoparticles (HANPs) by the coprecipitation method using calcium D-gluconate and potassium hydrogen phosphate as the sources of calcium and phosphate ions, respectively, and the triblock copolymer F127 as a ...

Electrostatic Self‐Assembly Induced Nest‐Like MXene Networks on Fabric for Ultra‐Broadband Flexible Absorption

open access: yesAdvanced Science, EarlyView.
In this study, an electrostatically self‐assembled WPU‐MXene@FC flexible fabric constructs a “nest‐like” structure on fibers, building construct MXene multiple loss paths, achieving ultra‐wideband absorption of 25.3–1200 GHz in a thickness of 1.8 mm, while also exhibiting superhydrophobicity, acid and alkali resistance, and bending resistance ...

Self‐Assembly Ordered Layered Gels for Thermochromic Smart Windows With Excellent Electromagnetic Shielding Properties

open access: yesAdvanced Science, EarlyView.
Metal‐ion‐coupled self‐assembled layered gels were prepared using a simple sol–gel method, successfully integrating electromagnetic shielding and thermochromic functions into the material. SCa‐1, which exhibits the best overall performance, achieves an electromagnetic shielding efficiency of up to 72.49 dB, while maintaining a visible light ...

Lighting up Macrophage Reprogramming Assists Immunosuppressive Niche Modulation in Primary Tumors and Tumor‐Draining Lymph Nodes of Breast Cancer

open access: yesAdvanced Science, EarlyView.
This study develops an intelligent NIR‐II‐responsive nanoplatform to combat immunosuppression in breast cancer. It enables real‐time visualization of macrophage activity via “off‐on” fluorescence while simultaneously reprogramming macrophages through the CSF‐1R and CD47‐SIRPα pathways.

Deep Eutectic Polymer Electrolyte with Competitive Hydrogen‐Bonding Coordination for High‐Voltage Nickel‐rich Lithium Metal Batteries

open access: yesAdvanced Science, EarlyView.
To stabilize high‐voltage Li||NCM811 batteries, we develop an in situ polymerized deep‐eutectic electrolyte (p‐DEPE) featuring competitive hydrogen‐bonding coordination. This design weakens Ni4+ adsorption, suppresses oxygen release, and enhances interfacial stability.
