Shellac‐Mediated Assembly of Nanoparticles for mRNA Delivery

Advanced Healthcare Materials, EarlyView.
A shellac‐mediated nanoparticle assembly strategy is presented, involving the complexation of mRNA and low‐molecular‐weight cationic molecules (e.g., polyethyleneimine, chitosan, lipids, and poly‐l‐lysine), followed by capping with shellac. This nanoparticle platform enables mRNA transfection following intravenous injection and facilitates gene editing

Neutrophil‐Mimetic MRI Enables Ultra‐Early Detection of Vascular Inflammation After Stroke

Advanced Healthcare Materials, EarlyView.
In this study, we developed neutrophil‐mimetic MRI probes that detect ultra‐early neuroinflammation following ischemic stroke by targeting E‐selectin. Within seconds of their injection, these microparticles mimic initial leukocyte adhesion to the activated cerebral endothelium.

Transient Charging of Mixed Ionic‐Electronic Conductors by Anomalous Diffusion

Advanced Materials, EarlyView.
This article explores charge transport in mixed ionic‐electronic conductors (MIECs) through electrochemical impedance spectroscopy and transient current analysis. Focusing on PEDOT:PSS, WO3, and n‐doped PBDF, it uncovers the impact of anomalous diffusion via fractional modeling. The study reveals key correlations that deepen understanding and guide the

Experimental investigation of the role of hexamethylenediamine in controlling fine migration in clay-rich sandstones

Scientific Reports
This research investigated the effect of hexamethylenediamine (HMDA) on the fine migration phenomenon in sandstones containing kaolinite clay. Fine migration, which refers to the movement of fine particles during oil and gas extraction, can lead to ...

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Microscopic Insights into Magnetic Warping and Time‐Reversal Symmetry Breaking in Topological Surface States of Rare‐Earth‐Doped Bi2Te3

Advanced Materials, EarlyView.
Magnetic doping of the topological insulator Bi2Te3 with erbium adatoms induces out‐of‐plane magnetism and breaks time‐reversal symmetry, opening a Dirac gap and driving a Fermi surface transition from hexagonal to star‐of‐David geometry. Microscopy, spectroscopy, and magnetic dichroism reveal atomically controlled magnetic interactions that tailor the
