Chiral supramolecular electronics for high‐efficiency circularly polarized organic light‐emitting diodes

FlexMat, EarlyView.
This perspective highlights supramolecular strategy for achieving band‐level chirality in vacuum‐deposited triazatruxene thin films, enabling circularly polarized organic light‐emitting diodes (OLEDs) with both high dissymmetry factor and external quantum efficiency, thereby overcoming the longstanding efficiency‐dissymmetry trade‐off in circularly ...

Beyond Tradition: An Integrated Toxicological, Ecological, and Public Health Perspective on Aristolochic Acids

Journal of Applied Toxicology, EarlyView.
ABSTRACT Aristolochia species have long been used in traditional medicine for their presumed anti‐inflammatory, analgesic and antimicrobial properties. However, extensive toxicological and epidemiological evidence now demonstrates that these plants contain aristolochic acids (AAs) I and II, highly potent nephrotoxic, genotoxic, and carcinogenic ...

Study of Scattering and Polarization of Light in Biological Tissue [PDF]

, 2013
Tkáňová optika nabývá rychle na významu a přesná znalost optických vlastností biologických tkání je podstatná pro výzkum v biomedicíně i pro kontrolu kvality potravin. Jestliže je vzorek tkáně osvětlen, dochází k mnohonásobnému odrazu světla.

How Does Entrepreneurs' Grit Predict Effectual Decision‐Making?

Strategic Change, EarlyView.
ABSTRACT Entrepreneurs' grit is one of the most relevant predictors of new venture performance. We investigate whether the “stubbornness” of entrepreneurs' grit negatively relates to their effectual decision‐making abilities. Understanding the underlying mechanisms is relevant because the effectual decision‐making abilities of founders are crucial for ...

Bayesian data reduction approaches in polarization imaging

EPJ Web of Conferences, 2010
The Stokes-Mueller formalism provides a coherent framework that permits obtaining polarization parameters from raw radiance acquisitions through a linear observation model. In polarization imaging, this observation model is extended to the whole image

Phenolic composition and multi‐target bioactivities of Globularia alypum extracts across seasons

JSFA reports, EarlyView.
Abstract Background This study investigates the influence of seasonal variation on the phytochemical profile and biofunctional activities of ethanolic leaf extracts from Globularia alypum. Leaves collected across four seasons were extracted with a hydroethanolic solvent (80:20, v/v) and analyzed by LC‐ESI‐MS/MS.

Uncertainty assessment for a novel optically shallow water radiometric acquisition platform

Limnology and Oceanography: Methods, EarlyView.
Abstract We present a novel motorized platform, a custom‐built jet‐ski designed for acoustic and radiometric measurements in optically shallow coastal waters. This platform integrates in‐water radiometers with single‐beam and multi‐beam acoustic sensors, along with a suite of active and passive instruments (conductivity‐temperature‐depth, fluorescence,
