Environmental Transformation and Trophic Transfer of Engineered Nanomaterials in the Agri‐Food Chain and Implications for human Health

ChemFoodChem, EarlyView.
ABSTRACT Engineered nanomaterials (ENMs) are increasingly applied in agriculture to improve crop yield, nutrient efficiency, and food quality. This study examines the environmental transformation of ENMs, their uptake in plants, and their transfer across the agri‐food chain leading to human exposure.

Coherent phonons in CdSe quantum dots triggered by ultrafast electron transfer

EPJ Web of Conferences, 2013
The origin of coherent oscillations in CdSe quantum dots and in the CdSe/methylviologen electron transfer system is studied. In CdSe/methylviologen coherent phonons are triggered by the electron transfer from the quantum dot to methylviologen.

Dual‐Mode Electrophoretic Displays Enabled by Quantum Dot‐Decorated PR48:2 Pigment Particles and TiO2 for All‐Weather Visibility, Excellent Bistability, and Enhanced Readability

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study presents a novel quantum dot electrophoretic display (QDEPD), which combines electro‐controlled reflection and optically‐triggered emission to achieve efficient multi‐modal switching within a single pixel. By incorporating multi‐component nanostructures, the system enhances functional integration and multi‐modal response capabilities.

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 ...
