Fluorene‐based blue emitters: On the path to electrically pumped organic lasers

FlexMat, EarlyView.
Electrically pumped efficient operation remains unrealized, a major challenge in optoelectronics. Fluorene‐based blue‐emitting semiconductors are promising gain media, thanks to their structural tunability and favorable emission properties. This review summarizes recent advances, highlights their reliability and versatility in lasing, and outlines key ...

Analytical Characterization of Quantum Dot Enhancement Films in Commercial Displays

Helvetica Chimica Acta, EarlyView.
Colloidal quantum dots (QDs) are increasingly used in displays, yet many compositions are regulated due to hazardous metal content. Their accurate identification and assessment are therefore essential. Here, a multimodal analytical workflow centered on LA‐ICP‐MS enables spatially resolved identification and classification of QDs in commercial quantum ...

Vascular Calcification: Mechanisms, Models, and Therapies

iNew Medicine, EarlyView.
ABSTRACT Vascular calcification represents an active multifactorial process that mirrors several key features of skeletal bone mineralization. Clinically, it is characterized by diminished arterial compliance and increased arterial wall stiffness, both of which serve as independent predictors of significant adverse cardiovascular events.

Reconstructing the Holocene explosive eruptive history of the Erciyes volcano (Turkey) using proximal and distal tephra records

Journal of Quaternary Science, EarlyView.
ABSTRACT Mount Erciyes, the largest active volcano of Central Anatolia (Turkey), erupted explosively during the Holocene, producing the Karagüllü, Perikartin and Dikkartin tuff rings. Even though major cities like Kayseri and its ~1 million residents sit directly on these pyroclastic deposits, the timing and magnitude of the explosive eruptions have ...

Nonlinear Resonance Modulation in Single‐Crystalline VO2‐Integrated Si Ring Resonator

Laser &Photonics Reviews, EarlyView.
This work first demonstrates a single‐crystalline VO2–Si hybrid ring resonator. The epitaxial lift‐off process enables high‐quality VO2 integration on the dissimilar Si photonic platform. The high‐quality VO2 film exhibits exceptional nonlinear resonance modulation and a steep optical transition across the metal‐insulator transition. ABSTRACT The metal‐

Ion Activation Methods for Top‐Down Proteomics

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Mass spectrometry (MS) has emerged as a premier method used to characterize the sequences of proteins. Top‐down proteomics aims to capture the multiple sources of structural diversity reflected in proteins, such as those that arise from alternative RNA splicing events or the addition of post‐translational modifications. Tandem MS (i.e., MS/MS)
