A Highly Stable Organic–Inorganic Hybrid Electron Transport Layer for Ultraflexible Organic Photodiodes

open access: yesAdvanced Materials, EarlyView.
Organic photodiodes (OPDs) with low dark current and stable detectivity under light irradiation, air exposure, and heating are realized using a nanoparticle‐based Zn‐chelated PEIE (PEI‐Zn NP) electron transport layer. This formulation effectively suppresses photocurrent degradation and dark current increase, ensuring enhanced environmental stability ...

Pairing N‐Vacancy and Adjacent Ni‐Sites in the Local Microenvironment to Regulate the Urea Oxidation Reaction Pathway With Enhanced Kinetics

open access: yesAdvanced Materials, EarlyView.
In nitrogen vacancies‐rich nickel nitride (Ni3N‐VN), a local microenvironment of nitrogen vacancies and adjacent Ni sites is formed. The electron‐rich Ni‐sites can be converted to NiOOH at a lower potential, and urea adsorption on the electron‐deficient nitrogen vacancy region is conducive to its partial dissociation, conceiving to efficient urea ...

Detecting Cr6+ at ≈100 pM Concentration with Fluorescence Enhancement Signatures in a Novel Eco‐Fluorophore: Matching WHO's 96 pM Recommended Standard for Drinking Water

open access: yesAdvanced Materials, EarlyView.
Through a dual‐functionalization strategy, carbon quantum dots (CQD) with exceptional fluorescence properties are engineered. These CQD are integrated with graphitic carbon nitride to form a 2D/2D heterostructure via both covalent and non‐covalent modification.

Ag‐Cu Nanoarchitecture for Enhanced LSPR Absorption: the Role of Surface Roughness and near‐field Interactions

open access: yesAdvanced Materials Interfaces, EarlyView.
This study investigates the plasmonic properties and biosensing capabilities of a nanocomposite incorporating Cu and Ag nanoparticles for detecting anti‐DbpA antibodies associated with Lyme disease. The enhanced LSPR response is explained through FDTD simulations of Cu–Ag near‐field interactions and increased surface roughness.

A generalization of concise words [PDF]

open access: yesarXiv
The study of verbal subgroups within a group is well-known for being an effective tool to obtain structural information about a group. Therefore, conditions that allow the classification of words in a free group are of paramount importance. One of the most studied problems is to establish which words are concise, where a word $w$ is said to be concise ...

Structural Insights Into Aluminum‐Doped Manganese Dioxides as Promising Materials for Direct Lithium Extraction: Modeling and Mechanism Study

open access: yesAdvanced Materials Interfaces, EarlyView.
A two‐stage sorption mechanism is proposed for Al‐doped HMnO in direct lithium extraction. Batch sorption experiments and modeling identify two key sorption sites on Al‐HMnO: surface sites (planar and edge) and vacancy sites (W). At pH 12, Stage I involves surface ion exchange, followed by Stage II, where surface complexation occurs between Li⁺ ions ...
