Femtosecond‐Laser Mould Texturing Enables Tunable Biointerfaces in COC Microfluidics

open access: yesAdvanced Materials Interfaces, EarlyView.
Femtosecond‐laser texturing of injection‐mould inserts enables scalable engineering of biointerfaces in cyclic olefin copolymer microfluidics. Replicated micro‐ and nano‐topographies modulate surface roughness and wettability, leading to texture‐dependent protein adsorption and cell adhesion without chemical post‐processing.

On the Friction and Wear Mechanisms of Electrified Steel Contacts in CO2: Unveiling the Role of Carbon‐Rich Tribofilms Under Dry Sliding Conditions

open access: yesAdvanced Materials Interfaces, EarlyView.
This study investigates friction and wear of AISI 52100 steel under dry sliding in CO2, air, and N2 atmospheres, with and without contact electrification. CO2 forms a stable carbon‐rich tribofilm that reduces friction by ∼30% and wear by ∼85%. High‐resolution TEM, EELS, and molecular dynamics reveal pressure‐dependent lubrication mechanisms, showing ...

High‐Power Rapid Laser‐Induced Synthesis of Multi‐functional Cobalt Metal‐Organic Framework With an Unprecedented Synthesis Efficiency

open access: yesAdvanced Materials Technologies, EarlyView.
Laser‐assisted synthesis enables rapid (within 1 h) and high‐yield (≥90%) production of Co‐MOFs with mesoporous structures, tunable magnetic and optical properties, and efficient adsorption of N2, CH4, and CO2 for low‐energy gas separation. DFT calculations elucidate the electronic structure and adsorption behavior.

Shaping Carbon Nitrides for Advanced Macrostructures

open access: yesAdvanced Materials Technologies, EarlyView.
This review examines how carbon nitride can be shaped through a range of printing and interfacial assembly methods. By bringing together additive manufacturing and liquid–liquid structuring concepts, carbon nitride is moving beyond its traditional powder‐based photocatalyst form toward digitally designed robust macroscale architectures with high design

Three‐Dimensional Printed Microarchitected Hierarchically Porous Biodegradable PLA/S/CNT Nanocomposite Electrodes for High‐Performance Lithium–Sulfur Batteries

open access: yesAdvanced Materials Technologies, EarlyView.
Hierarchically microarchitected PLA/S/CNT cathodes are fabricated via scalable fused filament 3D printing as high‐sulfur‐loading hosts for rechargeable lithium–sulfur batteries. The assembled Li–S cells with sulfur loadings up to 17 mg cm−2 deliver an areal capacity of 9.2 mAh cm−2 and retain 96% of their discharge capacity after 100 charge–discharge ...
