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.

Blending With Insulating Polymers Enables Stable Anti‐Ambipolar Characteristics in n‐Type Organic Mixed‐Conductors for Heterogeneous Spiking Neurons

open access: yesAdvanced Materials, EarlyView.
A polymer blend of n‐type OMIEC P(gNDI‐gT2) with insulating PMMA yields mechanically stabilized, anti‐ambipolar organic electrochemical transistors (OECTs) with tunable ionic‐electronic transport. This blending allows low‐power, fast‐spiking heterogeneous Hodgkin–Huxley neurons, enabling biomimetic frequency deconvolution and reservoir computing, which

Tailored Cationic Visible‐Light‐Active Interfaces for Sustainable, Biodegradable Nanofibers With Dual‐Mode Antimicrobial Activity and Robust Electrostatic Particle Capture

open access: yesAdvanced Materials, EarlyView.
Surface co‐functionalization of biodegradable nanofibers with sodium copper chlorophyllin and quaternary ammonium compounds achieves synergistic antimicrobial activity through combined photodynamic and contact‐killing mechanisms. The cationic surface provides humidity‐resistant electrostatic particle capture while maintaining rapid enzymatic ...

Ferroionic‐Assisted, Charge‐Driven Polymorphic Phase Engineering for Multilevel Memristive Devices

open access: yesAdvanced Materials, EarlyView.
A CuInP2S6/Mo0.92W0.08Te2 heterostructure enables a gradual semiconductor‐to‐semimetal phase transition through Cu+ ion migration and charge accumulation. The spatially engineered 2H/1T′ mixed phases produce continuously tunable conductance states in a two‐terminal geometry, while suppressing depolarizing fields and stabilizing the metastable 1T′ phase.

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 ...

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
