Fabrication of Pyridinic Nitrogen‐Functionalized Carbon Cloth for High‐Performance Iron‐Chromium Flow Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The carbon cloth electrode with targeted pyridinic nitrogen doping, achieved via urea pyrolysis, effectively modulates the adsorption of Cr(II) species and enhances electron transfer, leading to significantly improved kinetics of the Cr(II)/Cr(III) reaction. The material demonstrates a high discharge capacity of 689.3 mAh and an energy efficiency of 72.

Polymer Infiltration Into SURMOF Channels Enables Hydrophobic and Solid‐Like Slippery Functional Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
We report a polymer‐chain insertion strategy to fabricate pore‐threaded MOF thin films with precisely tuned surface chemistry and wettability. Grafting n‐alkane chains into the pillared layer Cu2(bdc)2(dabco) MOF thin film's vertical nanochannels enhances water stability, and induces hydrophobicity and lubricant‐free, solid‐like slippery behavior ...

Parallel 3D Bioprinting on SLIPS‐Microarrays

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces the first truly parallel 3D bioprinting method, enabling both the simultaneous fabrication of hundreds of cell laden hydrogel 3D structures and their HTS in individual liquid compartments. By integrating Digital Light Processing (DLP) stereolithography with functional micropatterns, the platform decouples printing time from array ...

Expansion of Micro-Annulus at the Second Cementing Interface During Construction of Underground Gas Storage From Old Well

open access: yesShiyou jixie
Debonding may occur at the second cementing interface during construction of underground gas storages (UGSs) from old wells. Based on the fluid-solid interaction theory and the cohesive zone model (CZM), the Cohesive unit in ABAQUS was used to establish ...

BACH, a Bayesian Optimization Protocol for Accurate Coarse‐Grained Parameterization of Organic Liquids

open access: yesAdvanced Functional Materials, EarlyView.
We present a fully automated Bayesian optimization (BO) protocol for the parameterization of nonbonded interactions in coarse‐grain CG force fields (BACH). Using experimental thermophysical data, we apply the protocol to a broad range of liquids, spanning linear, branched, and unsaturated hydrocarbons, esters, triglycerides, and water.

Elucidating the Role of Surface Ligands on the Oxidative Etching of Au Bipyramids During Photothermia Using Liquid Cell Transmission Electron Microscopy

open access: yesAdvanced Functional Materials, EarlyView.
Gold bipyramids can act as efficient plasmonic nanoheaters, but they often reshape during laser heating. This study shows that oxygen nanobubbles drive oxidative etching and that surface ligands control stability. CTAB‐ and citrate‐coated particles blunt and lose optical performance, whereas polystyrene sulfonate preserves shape and heating by ...
