Advanced Materials, EarlyView.Perovskite CsPbBr3 nanocrystals exhibit bright emission, fast response, and solution processability, but their nanoscale size limits efficient radiation detection. Organizing them into porous SiO2 mesospheres enhances radioluminescence up to 40 times, achieving an optimal combination of light yield, fast scintillation, and processability, providing a ...

Hue‐Resolved Strain Sensing in Mechanochromic Colloidal Photonic Crystal Films
Advanced Materials Interfaces, EarlyView.Despite the complexity of structural color in CPC films, hue extracted from optical images remains a reliable and sensitive indicator of strain‐induced color shifts. This image‐based approach captures consistent, material‐dependent mechanochromic responses and offers a scalable, real‐time alternative to spectroscopy for soft electronics, diagnostics ...

Advanced Materials Interfaces, EarlyView.In this study, CDs are incorporated into polymer or small‐molecule host materials to improve the morphology of EML films, balance charge transport and distribution, thereby enhancing charge recombination efficiency and device performance. Devices using PTTAA as the hole transport layer and TPBi as the host material exhibit the highest efficiency ...

The incidence chromatic number of some graph
International Journal of Mathematics and Mathematical Sciences, 2005 The concept of the incidence chromatic number of a graph was introduced by Brualdi and Massey (1993). They conjectured that every graph G can be incidence colored with Δ(G)+2 colors.

Graphs obtained from collections of blocks
Electronic Journal of Graph Theory and Applications, 2015 Given a collection of $d$-dimensional rectangular solids called blocks, no two of which sharing interior points, construct a block graph by adding a vertex for each block and an edge if the faces of the two corresponding blocks intersect nontrivially ...
