Quantum Well Superlattice Heteronanostructures for Efficient Photocatalytic Hydrogen Evolution.

In this study, we construct a quantum well effect-based two-dimensional Z-scheme superlattice heteronanostructure photocatalyst constructed from hydrogen-bonded porphyrin organic frameworks (HOFs) and carbon nitride. Porphyrin HOFs extend spectral absorption, while their π-conjugation and electron density variations significantly enhance charge separation and exhibit favorable alignment with the energy levels of carbon nitride, thereby enabling efficient charge transfer. Carboxylic acid channels in the HOFs further promote the decomposition of water molecules, thereby boosting hydrogen production.

Shape-Controlled Reversible Li Plating-Stripping for Stable and High-Rate Anode-Free Lithium Metal Batteries.

Anode-free lithium metal batteries are promising toward high-energy-density power sources with low-cost, but their practical applications are challenged by poor cycling stability and low rate capability. Herein, a shape change-free and lithium-free anode that well controls the reversible Li plating-stripping is reported, which is composed of a highly-ordered hollow ZnO matrix with a surface-coated lithium-phosphorus-oxynitride (LiPON) layer. The ZnO matrix supplies sufficient cavities and lithiophilic sites to facilitate uniform Li plating/stripping within the hollow cavity, while the LiPON layer maintains stable solid-electrolyte interphase from mechanical and electrochemical damage.

Bio-Inspired Retina by Regulating Ion-Confined Transport in Hydrogels.

The effective and precise processing of visual information by the human eye primarily relies on the diverse contrasting functions achieved through synaptic regulation of ion transport in the retina.

Herein, an ion-confined transport strategy is proposed to construct a bio-inspired retina by developing artificial synapses with inhibitory and excitatory contrasting functions.

A General Strategy for Exceptionally Robust Conducting Polymer-Based Bioelectrodes with Multimodal Capabilities Through Decoupled Charge Transport Mechanisms.

Efficient Metabolomics Profiling from Plasma Extracellular Vesicles Enables Accurate Diagnosis of Early Gastric Cancer.

Accurate diagnosis of early gastric cancer is valuable for asymptomatic populations, while current endoscopic examination combined with pathological tissue biopsy often encounters bottlenecks for early-stage cancer and causes pain to patients. Liquid biopsy shows promise for noninvasive diagnosis of early gastric cancer; however, it remains a challenge to achieve accurate diagnosis due to the lack of highly sensitive and specific biomarkers. Herein, we propose a protocol combining metabolomics profiling from plasma extracellular vesicles (EVs) and machine learning to identify the metabolomics discrepancies of early gastric cancer individuals from other populations.
