Diblock Copolymer Nanoparticles Act as Nanoreactors for the Synthesis of Sterically‐Stabilized Inorganic Oxide Particles in Non‐polar Media

Angewandte Chemie, EarlyView.
Poly(lauryl methacrylate)‐poly(2‐hydroxyethyl methacrylate) (PLMA‐PHEMA) diblock copolymer nanoparticles prepared in non‐polar media serve as nanoreactors for the in situ synthesis of silica from tetraethyl orthosilicate (TEOS). A silica mass loading of 17% as judged by thermogravimetric analysis (TGA) produces a highly transparent dispersion, and ...

Sonochemical coating of magnetite nanoparticles with silica

Ultrasonics Sonochemistry, 2010
Magnetite nanoparticles were coated with silica through the hydrolysis and condensation of tetraethyl orthosilicate (TEOS) under ultrasonic irradiation. The ultrasonic irradiation was used to prevent the agglomeration of the magnetite particles and accelerate the hydrolysis and condensation of TEOS.

Mechanically Assisted Magnetic Actuation in Ceramic‐Based Microscrolls for Fast and Durable Soft Robotic Systems

Advanced Materials, EarlyView.
Ceramic‐based V2O5/Fe3O4 hybrid films are shaped into butterfly‐proboscis‐inspired microscroll actuators. Magnetic triggering initiates unrolling, while geometry‐programmed elastic strain energy drives rapid recoil, enabling fast, reversible, durable, and load‐bearing actuation under near‐field magnetic stimulation.
