Color Routing and Beam Steering of Single‐Molecule Emission with a Spherical Silicon Nanoantenna

open access: yesAdvanced Functional Materials, EarlyView.
We experimentally demonstrate broadband directional emission from single molecules using a single spherical silicon nanoparticle assembled via DNA origami. By varying nanoparticle (NP) size and emitter position, we achieve unidirectional emission, beam steering, and color routing at the nanoscale, revealing modal interference as the underlying ...

Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films

open access: yesAdvanced Functional Materials, EarlyView.
Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...

Inducing Ferromagnetism by Structural Engineering in a Strongly Spin‐Orbit Coupled Oxide

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Magnetic materials with strong spin‐orbit coupling (SOC) are essential for the advancement of spin‐orbitronic devices, as they enable efficient spin‐charge conversion, complex magnetic structures, spin‐valley physics, topological phases and other exotic phenomena.

Consumer Perceptions and Purchase Behavior Towards Plant-Based Eggs: A Vignette Experiment

open access: yesFoods
The plant-based eggs category is growing rapidly; however, there is limited research on consumer behavior towards plant-based eggs. We explore consumer perceptions and investigate factors affecting the likelihood of purchase for plant-based eggs by using

Elucidating the Role of Surface Ligands on the Oxidative Etching of Au Bipyramids During Photothermia Using Liquid Cell Transmission Electron Microscopy

open access: yesAdvanced Functional Materials, EarlyView.
Gold bipyramids can act as efficient plasmonic nanoheaters, but they often reshape during laser heating. This study shows that oxygen nanobubbles drive oxidative etching and that surface ligands control stability. CTAB‐ and citrate‐coated particles blunt and lose optical performance, whereas polystyrene sulfonate preserves shape and heating by ...

Age and Sex Effects in Anchoring Vignette Studies: Methodological and Empirical Contributions

open access: yesSurvey Research Methods, 2013
Anchoring vignettes are an increasingly popular tool for identifying and correcting for group differences in use of subjective ordered response categories. However, existing techniques to maximize response consistency (use of the same standards for self-

Using a Vignette in Qualitative Research to Explore Police Perspectives of a Sensitive Topic: “Honor”-Based Crimes and Forced Marriages

open access: yesInternational Journal of Qualitative Methods, 2020
This article examines how a vignette presented to participants during qualitative research interviews was successful in gathering information on the perceptions of 32 police officers and 14 civilians regarding “honor”-based crimes and forced marriages ...

Sensitized Triplet Exciton Generation in Nanostructured Polymer Scintillators: Toward Improved γ/Neutron Discrimination

open access: yesAdvanced Functional Materials, EarlyView.
Rapid γ/neutron discrimination through PSD is achieved in liquid droplet containing nanostructured polymeric scintillator where a TTA‐active dye is dissolved. The inclusion of a properly selected and dosed sensitizer metalated porphyrin enhances discrimination sensitivity and speed by doubling the density of annihilating triplets and increasing the ...
