Bridging Biosensing and Hardware‐Level Data Security With a Conjugated Radical Polymer

Advanced Materials, EarlyView.
A conjugated radical polymer provides two complementary functions within a common material platform: sensitive dopamine biosensing and device‐specific stochastic electrical responses for security. The work demonstrates a materials‐based approach for combining bioelectronic signal acquisition with hardware‐level authentication while maintaining the ...

Charge Storage and Dark Photocatalysis in Multivariate Ti‐Based Metal‐Organic Frameworks

Advanced Materials, EarlyView.
The mixed‐linker series of the titanium‐based metal–organic framework COK‐47 enables systematic tuning of photoresponsiveness and (dark) photocatalytic activity, deepening our understanding of structure‐property‐function relationships. Tailored metal‐to‐ligand charge transfer between the secondary building units (metal‐oxo layers and organic linkers ...

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

Advanced 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.

Defect‐Driven Charge Separation in Ba‐Doped SrTiO3: Correlating Photoelectrochemical Performance With Dye‐Selective Photocatalysis

Advanced Materials Interfaces, EarlyView.
Ba‐doped SrTiO3 perovskites establish a direct correlation between photoelectrochemical activity and photocatalytic performance. Optimized Ba0.5Sr0.5TiO3 exhibits enhanced charge separation, photocurrent generation, and visible‐light‐driven dye degradation through defect‐induced oxygen vacancies and lattice distortion.

Reduced Graphene Oxide Enhances the Vascular Organization and Contractile Performance of Fibrin‐Gelatin‐Based Engineered Cardiac Tissue

Advanced Materials Interfaces, EarlyView.
Fibrin–gelatin hydrogels functionalized with reduced graphene oxide create a mechanically stable and bioactive 3D environment for engineered cardiac tissue. The composite matrix promotes endothelial lumen formation, enhances sarcomeric protein expression, and increases contractile performance of embedded cardiomyocytes.

Exogenous ascorbic acid scarcely ameliorates inhibition of photosynthesis in rice leaves by O3

Plant Production Science, 2017
The role of ascorbic acid on acute O3-induced inhibition of photosynthesis in solution-cultured paddy rice was evaluated. As pre-treatment, ascorbic acid (0, 5, and 10 mM) was added to the culture solution for 5 d before 5 h of O3 exposure (0, .1, and .3
