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 ...

Hydrogen Migration Enhances Proton‐Coupled Electron Transfer in an S‐Scheme Heterojunction for High‐Efficiency Photocatalysis

Carbon Energy, EarlyView.
Precisely directed built‐in electric field in an S‐scheme heterojunction synergizes photogenerated charge separation with interfacial proton migration, thus co‐localizing electrons and protons on the NOH surface and boosting proton‐coupled electron transfer kinetics in the rate‐determining hydrogen release step. ABSTRACT The kinetic bottleneck in solar‐

Preparation of Porous MOF‐Polymer Composites via High Internal Phase Pickering Emulsions for Dye Adsorption Applications

Chemistry – A European Journal, EarlyView.
A versatile method was developed to fabricate hierarchically porous monoliths using UiO‐66/TOCNC composites as Pickering emulsion stabilizers. The resulting polyHIPEs, produced under mild and scalable conditions, showed confirmed structural integrity through TGA, XRD, SEM, BET, and FT‐IR.

Modelling of continuous low‐temperature emulsion co‐polymerization in 3D‐printed reactor

The Canadian Journal of Chemical Engineering, EarlyView.
A kinetic model for the emulsion copolymerization of butyl acrylate/styrene at low temperatures is proposed and validated against experiments with a redox initiator system. The model was successfully transferred to a 3D‐printed tubular reactor and conversions of more than 80% and small particles sizes below 40 nm were observed.

Double Sided Traction Force Microscopy: A Method to Confine Cells for Physiologically Relevant Force Measurements

Cytoskeleton, EarlyView.
ABSTRACT In this paper we describe a technique to make a confined environment of variable stiffness that is suitable for high‐resolution live‐cell imaging. This versatile and adaptable technique enables cell confinement between soft elastic surfaces made from polyacrylamide gels.

Going from Pt to PGM‐free Catalysts: Effects of Ink Compositions on PEM Water Electrolysis

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Optimisation of cathode ink formulations regarding the ratio between catalyst, carbon and binder results in a boost in PEM water electrolysis performance. The optimisation can be transferred from pentlandites to platinum and selenide catalysts, wherein the metal chalcogenides show a stronger performance enhancement.

Segmental Hair Analysis of Diphenhydramine and Cyclizine Following a Single Dose

Drug Testing and Analysis, EarlyView.
A single oral dose of diphenhydramine and cyclizine can be quantified in human head hair for a minimum of 5 months and, in certain cases, for up to 1 year following intake. Among 12 study participants, the measured concentrations ranged from 0 to 610 pg/mg within 1 year post‐intake.

Advancing mine pillar design: Evaluating traditional methods and integrating AI for enhanced stability of pillars in the Great Dyke, Zimbabwe

Deep Underground Science and Engineering, EarlyView.
B1 is bord width 1, B2 is bord width 2, L is the pillar length, W is the pillar width, red color and letter A represent the pillars, and white color and number 1 represent excavated areas. Pstress is the average pillar stress; σv is the vertical component of the virgin stress, MPa; and e is the areal extraction ratio. e = B o B o + B P ${\rm{e}}=\frac{{
