Real‐time biosensing of Parkinson's disease biomarkers via NIR‐activated upconversion nanoparticles

BMEMat, EarlyView.
Schematic illustration of the luminescence resonance energy transfer‐driven core‐shell‐shell UCNPs (cssUCNPs@Fluo4) nanoprobe for simultaneous monitoring of Ca²⁺‐temperature dynamics in Parkinson's disease models. Abstract Parkinson's disease (PD) is a progressive neurodegenerative disorder with incompletely understood pathophysiology, necessitating ...

Tuning the Geometric and Electronic Structures in PtMn/SiO2 Catalysts via Oxygen Plasma Treatment for Enhanced Propane Dehydrogenation

Carbon and Hydrogen, EarlyView.
Oxygen plasma treatment promotes Pt dispersion, reducing the average Pt particle size of PtMn catalyst from 2.7 to 1.2 nm, and increases the electron cloud density of Pt. The optimized catalyst exhibits excellent mass‐normalized activity (171 molC3H8·gPt−1·h−1) and an ultralow deactivation rate constant, outperforming most reported Pt‐based catalysts ...

Ultra‐High‐Efficiency On‐Chip CO2 Conversion by Nanosecond Self‐Pulsing Micro‐Plasma Devices

Carbon Energy, EarlyView.
A micro‐plasma chip with sub‐10‐μm electrode gaps is introduced for efficient CO2‐to‐CO conversion. The device self‐converts a DC power supply into nanosecond pulses, producing field‐emission electrons that vibrationally excite CO2, driving dissociation via the ladder‐climbing mechanism. A scaled‐up chip array achieves 30% single‐pass conversion and 50%

Insights Into the Effect of Humic Acids Extraction From Coal on Hard Carbon Microstructure and Sodium Storage Properties

Carbon Energy, EarlyView.
This study employs a simple solid‐phase alkali‐oxygen oxidation (SAO) method to extract inherent components (humic acids) from coal. We successfully extracted yellow, brown, and black humic acids by adjusting the amount of alkali. Among them, brown humic acid extraction created abundant ultra‐micropores and closed pores, greatly enhancing sodium ...

High Thermoelectric Performance Achieved by Manipulating the Band Structure and Lattice Dislocations in n‐Type Ge/Pb/Br Codoped Polycrystalline SnSe

Carbon Energy, EarlyView.
Pb/Ge/Br codoping in n‐type polycrystalline SnSe induces band convergence and high‐density dislocations, yielding a high power factor of 7.47 μW cm−1 K−2 and ultralow lattice thermal conductivity. Consequently, a peak ZT of 1.6 is achieved, overcoming the traditional performance limitations of n‐type SnSe.

Probing the Influence of Sulfur–Aromatic Interactions on the Electronic Structure of Gas‐Phase Peptides

Chemistry – A European Journal, EarlyView.
Just as fingerprints reveal identity, spectroscopic fingerprints reveal molecular secrets. In this article, we show parts of the unique fingerprint of the sulfur–aromatic interaction. By measuring how this force alters the electronic structure of gas‐phase peptides, we provide a fundamental understanding of interactions that give insights into the ...
