Cat‐Vibrissa‐Inspired Biomass Fiber Aerogels for Flexible and Highly Sensitive Sensors in Monitoring Human Sport

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by cat vibrissae, biomimetic biomass PHFs/SA aerogels (BFAs) are developed via precursor‐assisted in situ polymerization and freeze‐synergistic assembly. These ultralight, porous pressure sensors exhibit high sensitivity and excellent durability, enabling pulse detection, handwriting recognition, Morse code transmission, and notably real‐time ...

Upconversion Nanoparticle‐Covalent Organic Framework Core–shell Particles as Therapeutic Microrobots Trackable With Optoacoustic Imaging

open access: yesAdvanced Materials, EarlyView.
Upconversion nanoparticle‐covalent organic framework core–shell particles provide enhanced contrast for optoacoustic imaging by leveraging the optical absorption of upconversion luminescence within the covalent organic framework matrix. Beyond their role as contrast agents, these particles enable customizable therapeutic agent loading and release, as ...

Industry‐Compatible Fully Laminated Perovskite‐CIGS Tandem Solar Cells with Co‐Evaporated Perovskite

open access: yesAdvanced Materials, EarlyView.
In this work, a highly efficient bilayer methylammonium lead iodide perovskite is fabricated using a scalable co‐evaporation technique. This strategy enhances the film's stability, allowing the deposition of a tin oxide buffer layer via atomic layer deposition without damaging the perovskite.

Magnetically “Programming” Cobalt‐Doped Iron Oxide Nanoparticles for Localized Induction Heating: Triggering a Collective Effect of Magnetic Moment Alignment on Demand

open access: yesAdvanced Materials, EarlyView.
This study demonstrates enhanced induction heating in cobalt‐doped iron oxide nanoparticles via specific pre‐magnetization, induced by the pre‐alignment of magnetic moments. By correlating Co content with magnetic properties, the research highlights how magnetic pre‐programming enables localized, on‐demand debonding in composites.

Realization of Aqueous Processed LiNi0.5Mn1.5O4 through the pH Optimization of Polyacrylate Binders

open access: yesAdvanced Sustainable Systems, EarlyView.
Partly neutralized polyacrylate binders enable aqueous processing of LiNi0.5Mn1.5O4 (LNMO) cathodes by buffering the slurry pH within the aluminum current collector's passivation region. Optimal performance is achieved at binder pH 5, matching polyvinylidene difluoride (PVDF)‐based systems in LNMO‖Li4Ti5O12 (LTO) full cells, while higher pH leads to ...

Self‐Adjusting Engineered Probiotic for Targeted Tumor Colonization and Local Therapeutics Delivery

open access: yesAdvanced Science, EarlyView.
Zou et al. developed an engineered strain of Escherichia coli Nissle 1917 with precise targeting abilities for colonization and on‐demand payload release. The engineered probiotic survives and embolizes tumors only in the presence of more than 5 mM L‐lactate. Furthermore, the introduction of an α‐hemolysin circuit enhances its anti‐tumor effect.
