Ionic Cocrystal Programming of Spatial Ionic Organization in Carbon Nitrides Enables Highly Efficient H2O2 Photosynthesis

open access: yesAdvanced Materials, EarlyView.
Ionic cocrystal‐programmed ionic organization establishes a general strategy for electrostatic programming in polymeric photocatalysts. ABSTRACT Controlling the spatial organization of ions in polymeric photocatalysts remains a fundamental challenge for optimizing charge transport and catalytic selectivity in solar‐driven hydrogen peroxide (H2O2 ...

Case Report: A rare presentation of short posterior ciliary artery occlusion with paracentral acute middle maculopathy

open access: yesFrontiers in Medicine
The occlusion of the short posterior ciliary arteries (SPCAs), a severe yet infrequent ocular vascular pathology, becomes particularly uncommon when it coexists with paracentral acute middle maculopathy (PAMM).

Biomass DNA: An Emerging Building Block for Advanced Materials

open access: yesAdvanced Materials, EarlyView.
Biomass DNA is rapidly emerging from its traditional role as a genetic blueprint to serve as a versatile abundant, highly programmable polymeric building block. This review highlights the transformation of macroscopic bulk biomass DNA into next generation of functional materials, spanning from dynamic hydrogels, sustainable bioplastics, and high ...

Vitamin C‐Induced Photo‐Redox Threshold Enables High‐Fidelity Volumetric Printing of Collagen

open access: yesAdvanced Materials, EarlyView.
Tomographic volumetric printing (TVP) of native proteins is limited by uncontrolled background crosslinking. Here, vitamin C is introduced as a biocompatible redox regulator to establish a tunable nonlinear polymerization threshold response for TVP.

From Water Vapor Transmission Rate (WVTR) to Intrinsic Water Vapor Permeability (WVP)

open access: yesAdvanced Materials, EarlyView.
Breathable membranes can appear less permeable when the measurement apparatus limits vapor transport. A calibrated four‐step model describes membrane permeation and apparatus effects as resistances in series under a common chemical‐potential driving force.

Life‐Like Ferrous Oxide Microspheres from Kombucha

open access: yesAdvanced Materials Interfaces, EarlyView.
Kombucha bacterial cellulose, sodium alginate, and ferrous nitrate self‐assemble into membrane‐enclosed iron oxide microspheres. These microspheres bud daughter vesicles, sustain 24‐h electrochemical oscillations, and filter theta‐band signals.

Spatial Homeotropic and Planar Liquid Crystal Alignment Patterning

open access: yesAdvanced Materials Interfaces, EarlyView.
A voltage‐assisted two‐step photoalignment methodology achieves precise micro‐patterning of alternating planar and homeotropic liquid crystal domains. Applying an AC electric field during in situ laser illumination minimizes phase retardation, reducing the required exposure dose. This cooperative mechanism enables high‐resolution spatial patterning and
