Recent advances and prospects for high‐efficiency blue hot exciton organic light‐emitting diodes

open access: yesFlexMat, EarlyView.
Blue organic light‐emitting diodes (OLEDs) face great challenges in achieving the balance between color purity, device efficiency, and stability. Hot exciton materials offer a solution by rapidly converting non‐emissive triplet excitons into singlet ones through a high‐lying reverse intersystem crossing process.

Humanism in the Age of Hyperreality: A Speculative Critique of AI Therapybots and the Neoliberal Commodification of Human Beings

open access: yesThe Journal of Humanistic Counseling, EarlyView.
ABSTRACT This article examines the future place of humanistic counseling, assuming the successful mass deployment of artificial intelligence therapy chatbots (AITCs). We systematically identify the limitations of AITCs through the lens of Jean Baudrillard's view on simulacra and hyperreality and identify five collective psychosocial consequences of ...

Gradient‐Structured Polymer Fiber Mats for Broadly Tunable Multicolor and White Lasing

open access: yesLaser &Photonics Reviews, EarlyView.
Hierarchically engineered electrospun fiber mats containing separated red, green, and blue dyes enable highly tunable multicolor and white random lasing. Spatially controlled dye distribution suppresses energy transfer, allowing precise color adjustment across wide color gamuts and accurate reproduction of daylight white standards.

First 20 Years of Orbitrap Mass Spectrometry as the Mainstream Analytical Technique

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT This review traces the first 20 years of Orbitrap mass spectrometry as a mainstream high‑resolution and accurate‑mass (HR/AM) technology. It outlines the historical development of the Orbitrap analyzer, the evolution of major instrument families, and the key technological innovations that enabled its widespread adoption. Particular emphasis is

Quantifying Night Sky Brightness as a Stressor for Coastal Ecosystems in Moreton Bay, Queensland

open access: yesRemote Sensing
Growing light pollution is increasingly studied in terrestrial environments. However, research on night lights in coastal ecosystems is limited. We aimed to complement spaceborne remote sensing with ground-based hemispheric photos to quantify the ...

Osmotic Remodeling of Extracellular Vesicles for Precision Nanomedicine

open access: yesSmall, EarlyView.
Hypotonic lysis in bidistilled water is used to remodel B lymphocyte–derived extracellular vesicles into cargo‐depleted, structurally preserved nanovesicles. The process reduces intraluminal proteins and nucleic acids, reshapes membrane composition, and enhances tumor‐cell uptake in vitro, while allowing proof‐of‐concept reloading with exogenous agents,

Top‐Down Synthesis of Wurtzite Gallium Nitride Colloidal Quantum Dots via Defect‐Driven Fragmentation

open access: yesSmall Methods, EarlyView.
Conventional synthesis of wurtzite gallium nitride (GaN) quantum dots (QDs) demands extreme heat. We overcome this via defect‐driven fragmentation at 50°C. Nitrogen‐rich solvents provide a thermodynamic driving force that promotes the outward movement of internal defects.

Post-midnight purple arc and patches appeared on the high latitude part of the auroral oval: Dawnside counterpart of STEVE?

open access: yesEarth, Planets and Space
The phenomenon known as strong thermal emission velocity enhancement (STEVE) is a purple/mauve arc-shaped atmospheric glow observed at lower latitudes of the auroral oval on the duskside.

“Shadow Mask‐Based RGB Color Patterning in QLED Panels via Selective Quenching by Metals”

open access: yesSmall Methods, EarlyView.
A shadow mask‐based RGB color‐patterning approach for QLED panels is presented, in which ultrathin metal layers (1–2 nm) are deposited through shadow masks to selectively quench the luminescence of QD layers in a tandem stack. This enables different regions to emit different colors under electrical bias, offering a scalable route compatible with ...
