Lattice Strain and Piezoelectric Field Modulated Piezo‐Photocatalytic Nitrate‐to‐Ammonia Conversion in Chemically Bonded S‐Scheme Heterojunction

open access: yesAdvanced Science, EarlyView.
Under ultrasonic excitation, 5% compressive strain optimizes the ZnO@ZnSe heterojunction. The strain enhances H2O dissociation into active *H on Zn sites and NO3− adsorption on Se sites, facilitating their hydrogenation into NH4+ with optimal kinetics and thermodynamics. Abstract Piezo‐photocatalysis provides an efficient approach to harness mechanical

RADA16 and SAAP148 Peptide‐Modified Collagen Self‐Assembled Hydrogels for Accelerated Healing of Infected Wounds

open access: yesAdvanced Science, EarlyView.
Collagen type I (Col I) is integrated with self‐assembling peptide RADA16 and loaded with anti‐bacterial peptide SAAP148 to develop a self‐assembled nano‐microstructure hydrogel (Col I‐RADA16‐SAAP148, CRS) without chemical cross‐linkers. CRS exhibits excellent mechanical properties, sustained SAAP148 release to inhibit bacterial infection, macrophage ...

Quantitative Stain Mapping in X‐Ray Virtual Histology

open access: yesAdvanced Science, EarlyView.
Virtual histology promises 3D tissue examination without physical sectioning, yet has lacked the tissue‐specificity of conventional pathology. This work demonstrates the first quantitative three‐dimensional stain mapping at histologically relevant resolution, separating contrast agent from tissue to reveal cellular features such as nuclei. The approach

Non‐Volatile Phase Modulation with Ultralow Energy Consumption Enabled by 2D Ferroelectric/TMD Heterostructures

open access: yesAdvanced Science, EarlyView.
We demonstrate a hybrid WS2/CuInP2S6/graphene heterostructure integrated on a silicon nitride microring resonator for non‐volatile optical phase modulation with ultra‐low energy consumption and low insertion loss. While CIPS alone does not provide efficient optical index modulation, the engineered proposed device structure converts ferroelctric domain ...

Halide‐Exchange Arrest Enables Reabsorption‐Free CsPbCl3/CsPbI3 Perovskite Core/Shell Nanocrystals

open access: yesAdvanced Science, EarlyView.
Achieving large Stokes shifts in perovskite nanocrystals is challenging due to halide mobility that disrupts stable core–shell structures. Using CdCl2 passivation, this work stabilizes CsPbCl3/CsPbI3 heterostructures, yielding a ≈1.2 eV Stokes shift, high quantum yield, and fast exciton transfer, enabling reabsorption‐free emitters for advanced ...

In Situ Quantization with Memory‐Transistor Transfer Unit Based on Electrochemical Random‐Access Memory for Edge Applications

open access: yesAdvanced Science, EarlyView.
By combining ionic nonvolatile memories and transistors, this work proposes a compact synaptic unit to enable low‐precision neural network training. The design supports in situ weight quantization without extra programming and achieves accuracy comparable to ideal methods. This work obtains energy consumption advantage of 25.51× (ECRAM) and 4.84× (RRAM)

Toward Complete CO2 Electroconversion: Status, Challenges, and Perspectives

open access: yesAdvanced Energy Materials, EarlyView.
Electrocatalytic CO2 reduction and CO2 batteries face challenges in achieving complete CO2 conversion with high conversion rates and Faradaic efficiency simultaneously. Existing systems compromise one for the other with incomplete CO2 conversion and inefficiencies, hindering practical applications. This perspective highlights state‐of‐the‐art progress,
