Liquid‐Phase Fabrication of Janus 2D Materials: Defect‐Rich MoS2 Ultrathin Layers Asymmetrically Decorated with Au Nanoparticles

open access: yesSmall, EarlyView.
This work presents a versatile strategy for asymmetrically decorating MoS2 flakes using SiO2 microspheres as masking templates. The Janus MoS2 exhibits a 1.9‐fold enhancement in photoluminescence (PL) due to the incorporation of Au nanoparticles (NPs), primarily dominated by B exciton emission, which is attributed to defect‐rich structures.

Tailorable Curie Temperature in Zinc Ferrite Nanoparticles With Finely Tunable Induction Heating Profiles Between Room Temperature and 250°C

open access: yesSmall, EarlyView.
A spray‐drying‐based synthesis enables the formation of zinc ferrite nanoparticles with customizable induction heating from room temperature to 250°C by varying the zinc content and postsynthesis annealing temperatures. The aqueous dispersions are colloidally stable and heat up to biologically relevant thresholds. Hence, this approach offers a scalable
