Spray‐Assisted Fabrication of Cellulose Photonic Pigments on Superhydrophobic Surfaces

Advanced Materials, EarlyView.
A method to directly produce structurally colored microparticles by drying cholesteric cellulose nanocrystal microdroplets on a superhydrophobic surface is reported. This approach has several key advantages that can unlock large‐scale fabrication of sustainable photonic pigments, including exploiting existing industrial techniques (e.g. aerosolization),

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

Advanced 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 ...

Formulation and Characterization of Novel Ionizable and Cationic Lipid Nanoparticles for the Delivery of Splice‐Switching Oligonucleotides

Advanced Materials, EarlyView.
Lipid nanoparticles (LNPs) of unconventional composition and defined structures are investigated as small oligonucleotide carriers. A composition is identified that outperforms Onpattro in cargo delivery to HeLa cells. The structure of these LNPs resembles a micellar cubic phase not commonly associated with high‐performing LNPs.

Photo‐Induced Bandgap Engineering of Metal Halide Perovskite Quantum Dots In Flow

Advanced Materials, EarlyView.
This work presents a photochemical synthetic route for bandgap engineering of metal halide perovskite quantum dots. Utilizing a material‐efficient microfluidic platform, the underlying mechanism of the photo‐induced anion exchange reaction (PIAER) of metal halide perovskite quantum dots is unveiled and first instance of the PIAER‐enabled synthesis of ...

A Multifunctional Binder for Current‐Collector‐Free Zn Powder Anodes

Advanced Materials, EarlyView.
By introducing abundant polar groups as Zn2+ absorption sites and hydrogen bond arrays, a protein structure‐derived binder for ZP anode and iodine cathode is proposed. This design can regulate the Zn2+ flux, benefit the formation of free‐standing electrode, inhibit the side reactions, suppress the shuttle effect of polyiodides, and enable the large ...

Pressure Induced Molecular‐Arrangement and Charge‐Density Perturbance in Doped Polymer for Intelligent Motion and Vocal Recognitions

Advanced Materials, EarlyView.
The sidechain doped polymer is investigated to have great potential for pressure detection due to the advantages including molecular rearrangement and charge‐density perturbance induced by micro‐mechanical deformation. This sensor displayed low‐pressure detection limit of 0.7 Pa as well as a rapid response time of 18.8 ms, enabling multi‐mode motion ...
