Low‐Profile, High‐Gain GRIN RF Lenses via Multi‐Material Vat Photopolymerization
Advanced Functional Materials, EarlyView.We investigate the opportunity of leveraging multi‐material vat photopolymerization printing to manufacture intricate lenses exhibiting permittivity gradients that can increase signal gain in transmitted radiofrequency signals in the X‐ and Ku‐bands. Lenses produced with more distinct low‐loss materials (up to 5) can deliver an 18 dB signal gain with a

Advanced Functional Materials, EarlyView.Bandgap‐engineered AlGaAs/GaAs heterostructures exhibit wavelength‐selective dual‐polarity photoelectrochemistry, switching from photocathodic to photoanodic response depending on excitation wavelength. The polarity transition is governed by band‐selective absorption, built‐in electric‐field‐driven carrier transport, and interfacial charge‐transfer ...

Design and Synthesis of Peptide‐Polyester Conjugates for Cell‐Mediated Scaffold Degradation
Advanced Healthcare Materials, EarlyView.This work describes polycaprolactone (PCL)‐based biomaterials engineered to degrade in response to cell‐secreted proteases. A fast‐degrading peptide (Fast) sequence is integrated into a PCL conjugate backbone to produce a biomaterial that is selectively degraded by multiple cell types compared to its scrambled control (ScrFast).

Multidimensional Cellular Micro‐Compartments to Model Invasive Lobular Carcinoma Dormancy
Advanced Healthcare Materials, EarlyView.Invasive lobular carcinoma (ILC) is an understudied subtype of breast cancer that is susceptible to late recurrences. In this study, micro‐compartmentalization techniques spanning multiple dimensions, including 2D, pseudo‐3D, and 3D, are integrated to uncover the mechanisms underlying ILC dormancy, revealing the central role of p27Kip1.

Advanced Healthcare Materials, EarlyView.Sweetosomes, a new class of fucose‐decorated liposomes, are developed via a one‐step microfluidic process without surface chemistry. This study elucidates their main caveolae‐mediated entry and distinct endosomal trafficking. These nanostructures demonstrate superior endosomal escape, organelle acidity modulation, and prolonged plasma persistence ...
