An Epigenetic Fate Converter Based on Nuclei‐Targeting Lipid Nanoparticles Drives Neuronal Programming of Stem Cells for Spinal Cord Repair

Advanced Functional Materials, EarlyView.
Schematic illustration of LNP‐MPG nuclei‐targeting delivery of HMW‐FGF2 promoting histone acetylation to regulate the fate of DPSCs and treat spinal cord injury. LNPs components include pHMW‐FGF2 plasmid, DSPC, Dlin‐MC3‐DMA, cholesterol, and PEG2000, and are modified with MPG to form HMW‐FGF2@LNP‐MPG (HLM). HLM nuclei‐targets DPSCs to deliver HMW‐FGF2,

Bio‐Inspired Multifunctional Superhydrophilic Coatings With Remarkably Fast Self‐Healing Abilities

Advanced Functional Materials, EarlyView.
We developed bio‐inspired multifunctional hydrogel‐based coatings that exhibit extremely fast/repeatable self‐healing abilities, long‐lasting anti‐fogging performance, superhydrophilicity in air, and underwater superoleophobicity. By doping multivalent metal‐ions into the hydrogel networks, which promoted hydrogen bonding formation and enhanced the ...

Heteroengineering‐Induced Electronic Reconstruction for Ammonium‐Ion Energy Storage

Advanced Functional Materials, EarlyView.
An integrated electronic reconstruction behavior is induced by local heteroengineering on VO2(B) electrode material surface of NH4+ supercapacitor, rationally modulating the electronic structure, enabling enhanced intrinsic conductivity and extra driving force for NH4+ intercalation reaction.

A coring method for lake surface sediments

, 1976
A technique for coring flocculent limnic sediments, involving the use of a Livingstone piston sampler and dry ice is described. The technique is most useful when detailed stratigraphic analysis of surface sediments is important.

A review on ice cores from temperate glaciers: Processes, signal preservation and paleoclimatic significance

Journal of Glaciology
Temperate glaciers, characterized by ice at the pressure-melting point and the coexistence of solid and liquid water, are generally considered unsuitable as natural archives because meltwater undermines the paleoclimatic signals they hold.

Protease‐Activated Theranostic Nanomedicine for Endometriosis Treatment

Advanced Functional Materials, EarlyView.
Endometriosis is a chronic gynecological disorder that affects a substantial proportion of reproductive‐aged women. In this study, we identify aberrant overexpression of matrix metalloproteinase‐9 (MMP‐9) in endometriotic lesions and develop a novel multifunctional nanomedicine that integrates MMP‐9‐targeted therapy, ratiometric photoacoustic (PA ...

Biomimetic Hybrid‐Membrane Nanoreactor for Deep‐Seated Photodynamic Immunotherapy of Hepatocellular Carcinoma via Dual Catalysis‐Enhanced ROS Amplification and cGAS‐STING Activation

Advanced Functional Materials, EarlyView.
UCNP@MnOx‐Hyp@HRM (UMHM) enables tumor targeting and accumulation. Under 808 nm NIR irradiation, PDT/CDT synergistically triggers ICD and cGAS–STING immunity for deep hepatocellular carcinoma therapy. ABSTRACT Photodynamic therapy (PDT) is promising against hepatocellular carcinoma (HCC).
