Dual pKa Lipid Nanoparticles for Lung‐tropic mRNA Delivery and pH‐Programmed Endosomal Escape

open access: yesAdvanced Science, EarlyView.
Lipid nanoparticles’ bottleneck lies in low endosomal escape efficiency and liver‐dominant delivery after intravenous administration. To overcome these limitations, we present a stepwise pH‐programmed lipid nanoparticle system enabled by our newly synthesized ionizable lipid.

Programmable Sequential 4D Actuation in Multistable Kirigami Metamaterials

open access: yesAdvanced Science, EarlyView.
This study presents a modular kirigami metamaterial framework enabling programmable multistability and sequential 4D actuation. By coupling geometry‐controlled multistability with material‐dependent recovery kinetics, spatiotemporal deformation can be precisely programmed.

Synergistic Grain Boundary and Phonon Engineering Enables Ultrahigh Thermoelectric Performance in Mg3(Sb, Bi)2‐Based Materials

open access: yesAdvanced Science, EarlyView.
Ta encapsulated melting and Cu doping synergistically engineer grain boundaries and phonon scattering in Mg3(Sb,Bi)2, enabling single‐crystal‐like carrier transport and high thermoelectric performance. ABSTRACT Thermoelectric Mg3(Sb, Bi)2 has emerged as a rising star in virtue of its promising thermoelectric performance and abundant constituent ...

Tau Aggregate Imaging and Transcriptomics of Alzheimer's Disease Brain at Different Stages of Disease

open access: yesAdvanced Science, EarlyView.
The protein aggregates and gene expression in the middle temporal gyrus (MTG) and somatosensory cortex (SOM) of the postmortem brains of 13 Alzheimer's disease patients were studied in detail, revealing that small hyperphosphorylated tau aggregates increase with Braak stage driven by microglial inflammation.
