Selective Transparent Contacts Based on a Hafnium‐Titanium Oxide Alloy with Optimized Band Alignment for c‐Si Solar Cells

open access: yesAdvanced Materials Interfaces, EarlyView.
This study explores the synthesis and properties of hafnium‐titanium oxide (HTO) alloys developed by low‐temperature atomic layer deposition (ALD) as selective contacts for crystalline silicon solar cells. X‐ray photoelectron spectroscopy (XPS), surface photovoltage (SPV), and ellipsometry are employed to estimate the band alignment at the c‐Si/HTO ...

Fabrication and Characterization of MWCNTs Decorated ZnO Nanograins Based Sensor for Enhanced Performance Toward CO2 Gas

open access: yesAdvanced Materials Interfaces, EarlyView.
The present work is concerned with the fabrication of CO2 sensors based on MWCNTs/ZnO material, which is obtained by RF magnetron sputtering and electron‐beam deposition methods. The sensor exhibits highly sensitive and selective behavior, high repeatability, and temporal stability at low CO2 concentrations.

Surface Coordination and Polymerization of Allyl Mercaptan Passivates the Oxidation of Copper

open access: yesAdvanced Materials Interfaces, EarlyView.
This study demonstrates that allyl mercaptan self‐assembles on the surface of copper via coordination and polymerization, forming an ultrathin polymeric passivation layer (8.06 ± 0.50 nm). The modified copper foil achieves a two‐order‐of‐magnitude anti‐corrosion performance enhancement across multi‐service environments. Abstract The oxidation of copper

Electrochemically Modified Mn₂P₄O₁₂ as an Emerging Catalyst for Oxygen Evolution Reaction

open access: yesAdvanced Materials Interfaces, EarlyView.
Mn₂P₄O₁₂ nanomaterials derived from MnO₂ nanosheets, act as pre‐catalysts and undergo in situ surface reconstruction during alkaline OER. The transformation yields MnO₂ and restructured Mn₂P₄O₁₂ phases, forming efficient active sites. This work highlights cyclotetraphosphate‐based catalysis and introduces a cost‐effective, stable material for enhanced ...

Red Blood Cell Membrane‐Camouflaged Red Phosphorus‐Modified C3N4 for Enhanced Tumoral Photodynamic Therapy

open access: yesAdvanced Materials Interfaces, EarlyView.
Photodynamic therapy (PDT) faces clinical challenges due to poor tumor targeting and systemic toxicity. Herein, a biomimetic C3N4‐RP@RBCm nanoplatform is developed via erythrocyte membrane encapsulation, enabling CD47‐mediated immune evasion and EPR‐driven tumor accumulation.
