“…The main steps in template methods include synthesizing the framework, depositing materials on the framework, and removing templates. [18] Liang et al used silica templets to fabricate pH-responsive Janus hollow spheres with a biodegradable PCL inner layer and pH-responsive poly PDEAEMA outer layer. [12a] Although hard templates such as silica spheres have excellent thermal stability and mechanical properties, it is more convenient to introduce functional groups on soft polymer templates.…”

Janus particles with different compositions and properties segmented to different regions on the surface of one objector provide more opportunities for interfacial engineering. As a novel interfacial active material, Janus particles integrate the amphiphilic properties of molecular surfactants and the Pickering effect of homogeneous particles. In this research, the outstanding properties of Janus particles on various interfaces are examined from both theoretical and practical perspectives, and the advantages of Janus particles over molecular surfactants and homogeneous particle surfactants are analyzed. We believe that Janus particles are ideal tools for interface regulation and functionalization in the future.

The size of in situ exsolved nanoparticles (NPs) significantly affects the electrochemical and electro‐catalytic properties of oxide supports. Unfortunately, the instrumental factor affecting the exsolved NP size in poly‐crystalline perovskite oxides is still unexplored. Herein, the inherent micro‐strain (ε) value as an unprecedented factor in controlling the exsolved NP size of Pr0.5Ba0.5‐xSrxFe0.85Ni0.15O3‐δ (x = 0.3, 0.4, and 0.5) is introduced, wherein smaller NP size is successfully obtained via strain relaxation strategy. The effect of exsolved NP size on the fuel oxidation reaction kinetics at high‐temperature regimes is evaluated in‐depth by using density functional theory (DFT) calculations. In accordance with the insights provided by DFT calculations, the electro‐catalyst featuring the smallest Fe3Ni NP size via strain relaxation strategy demonstrates exceptional electrochemical performance along with robust durability toward high‐temperature hydrogen oxidation reaction. This work presents scientific guidance for tailoring the exsolved NP size in perovskites, thereby paving the way for designing rational perovskite electro‐catalysts in various energy‐related applications.
