Optimized Selenium‐Doped Nanocomposites for Enhanced Polymer Gel Performance in Permeability Reduction

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Excessive water production in mature oil fields necessitates robust shut‐off treatments, yet conventional polymer gels often fail under high‐temperature and high‐salinity conditions. This study aims to enhance gel thermal stability and mechanical strength by incorporating selenium‐doped Ag/AgO–ZnO nanocomposites synthesized via a novel green ...

Recessed Microelectrodes as a Platform to Investigate the Intrinsic Redox Process of Prussian Blue Analogs for Energy Storage Application

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
A microelectrochemical analytical tool is proposed for the accelerated evaluation of the intrinsic electrochemical performance of Prussian‐blue analogues as solid active materials in Na+‐based batteries. By confining the solid active material inside a recessed microelectrode, accelerated voltammetric and galvanostatic cycling at high C‐rate become ...

Nano‐networks via reaction‐induced self‐assembly coordinate spatiotemporal multi‐drug delivery for acute kidney injury therapy

BMEMat, EarlyView.
Multifunctional nano‐networks (NNWs) are prepared via reaction‐induced self‐assembly (RISA) of spermidine (SPD), epigallocatechin gallate (EGCG), 2‐formylphenylboronic acid (2‐FPBA), and deferoxamine (DFO) through dynamic iminoboronate bonds. These NNWs leverage the oxidative AKI microenvironment to trigger disintegration, enabling site‐specific ...

Overcoming intranasal delivery barriers with ultrastable polyzwitterionic siRNA nanocages for enhanced glioblastoma therapy

BMEMat, EarlyView.
A ROS‐responsive, zwitterionic nanocage enables stable, intranasal siRNA delivery to glioblastoma, promoting deep tumor penetration via non‐degradative pathways and trigeminal nerve transport. This platform achieves durable gene silencing and tumor suppression, offering a non‐invasive, storage‐stable strategy for treating glioma and other neurological ...

A novel biomimetic liposome drug delivery system mediated by macrophage targeting for precision treatment of encephalitis

BMEMat, EarlyView.
An advanced macrophage‐mediated biomimetic liposome (AC‐LP@RAW) that can penetrate the BBB and precisely target inflammatory sites in the deep brain was established in this study based on the unique immune homing property of macrophages, and showed a significantly improved delivery of curcumin to the brain.

Transfersomes with core and surface‐loaded NF‐κB p65 siRNA for enhanced transdermal transfection and effective treatment of psoriasis

BMEMat, EarlyView.
TCPL, a transfersome with Tween 80 and PEI, enables efficient transdermal siNF‐κB delivery, resolving PEI's toxicity issue. It promotes lysosomal escape and effective transfection, silences NF‐κB, modulates immunity, and inhibits angiogenesis, alleviating psoriasis. With good biocompatibility, TCPL holds strong clinical translation potential. Schematic
