Shear-induced alignment of low-aspect-ratio nanorods for modulations of multiple optical properties

Abstract

Dynamic modulations of multiple optical properties in one system could bring new opportunities for applications in various areas. Here we report rheological modulations of birefringence and photonic bandgap in crystalline...

Research progress of dual-atom site catalysts for photocatalysis

“…6b and c). 109,110 In the formaldehyde pathway, COOH is usually formed by combining O atoms with the photocatalyst, and then formic acid (HCOOH) is generated. 111 A dimethylol radical is then generated by accepting the proton of formic acid.…”

Customizing catalyst surface/interface structures for electrochemical CO2 reduction

“…The incorporation of axial coordination, leading to the formation of a penta-coordinated structure, plays a pivotal role in regulating spin states and electronic properties, such as the d-band centers of the metal sites. 45 In this context, Chen et al successfully synthesized a Fe 1 N 4 -O 1 site with axial O coordination using a rapid pyrolysis and controllable activation strategy. 26 XAS and AC-HAADF-STEM conrmed this unique coordination structure.…”
