Reducing Interfacial Separation Force in High‐Speed Constrained‐Surface Projection Stereolithography Using a Dual‐Modulus Silicone Release Film

open access: yesAdvanced Materials Interfaces, EarlyView.
A dual‐modulus silicone release film creates distributed stress concentrations at high‐/low‐modulus boundaries, triggering multi‐site crack initiation and rapid interfacial detachment. The architecture lowers the peak separation force by 97.6%, shortens detachment time, and enables stable continuous projection stereolithography at 720 mm h−1, offering ...

A Self‐Cleaning Solar Evaporator Based on MXene/Aramid Nanofiber Aerogels for Efficient Water Desalination

open access: yesAdvanced Materials Interfaces, EarlyView.
This study develops a self‐cleaning solar evaporator based on MXene‐coated aramid nanofiber aerogels for efficient desalination under high‐salinity conditions. The cylindrical evaporator combines strong photothermal conversion, capillary water transport, and self‐rotation triggered by salt accumulation.

Wood‐Derived Nanocellulose‐Biocarbon Fresnel‐Zone Plate Lenses for Sub‐THz Frequency Applications

open access: yesAdvanced Materials Technologies, EarlyView.
Wood‐derived nanocellulose and lignin‐based biocarbon were combined to fabricate fully bio‐based Fresnel zone plate (FZP) lenses for sub‐terahertz frequencies. These sustainable FZP lenses exhibit low dielectric loss and high directivity, achieving performance comparable to that of metallic references, and remain functional under environmental stress ...

A U‐shaped Microfluidic Platform for Culturing Vascularized Colorectal Cancer Spheroids Reveals Tumor–Endothelial Crosstalk and Invasion‐Associated Remodeling

open access: yesAdvanced Materials Technologies, EarlyView.
A closed U‐shaped microfluidic platform symmetrically embeds a single, size‐controlled HT29 colorectal cancer spheroid within a GFP‐HUVEC‐laden fibrin matrix. HT29 spheroids are associated with hyper‐branched endothelial network remodeling, while vascularized co‐culture is accompanied by anisotropic protrusive growth and EMT‐like marker changes in the ...
