The present study focuses on the development and characterization of epoxy syntactic foam filled with epoxy hollow spheres (ESF/EHoS). The epoxy syntactic foam (ESF) was produced by embedding epoxy hollow spheres (EHoS) into a mixture of epoxy-hardener and 3% KOH solution. An innovative approach and simple procedure was implemented in the preparation of the EHoS where expanded polystyrene (EPS)...

Ceramic-based hollow spheres are considered a great driving force for many applications such as offshore buoyancy modules due to their large diameter to wall thickness ratio and uniform wall thickness geometric features. We have developed such thin-walled hollow spheres made of alumina using slip casting and sintering processes. A diameter as large as 50 mm with a wall thickness of 0.5-1.0 mm h...

A facile aerosol-spraying approach was developed to prepare mesoporous BiFeO(3) hollow spheres with enhanced activity and durability in visible photocatalysis.

A series of lanthanide oxide microspheres and hollow spheres have been fabricated by thermolysis of corresponding lanthanide coordination compounds formed via bottom-up self-assembly.

Monodisperse Cu2WO4(OH)2 round and elliptical hollow spheres have been successfully prepared by a ligand-assisted dissolution process, without any template or surfactant.

We first demonstrate a simple "one-pot" method to synthesis uniform Fe3O4 hollow microspheres in the presence of PEG in ethylene glycol by using urea to control their morphologies. The interior cavity of the hollow spheres can be tunable by reaction time. The Lamer model was used to explain the formation of magnetite hollow spherical structures based on the experimental observations. The obtain...

Nanostructured silicon hollow spheres with a thin shell have been synthesized by magnesium reduction of silica spheres, which possess a high BET surface area and are electrochemically active in capacitive energy storage with a maximum specific capacitance of 193 F g(-1) in the neutral Na(2)SO(4) aqueous solution.

H. H. Yu, X. Li, Z. G. Yuan, School of Material Science and Engineering, Shenyang Ligong University, Shenyang, China Hollow spheres structures of La0,7Sr0,2Ca0,1Co0,9Fe0,1O3–δ (LSCCT) have been synthesized via hydrothermal method using carbon spheres as template. The structure and electrical conductivity of obtained samples are characterized by X-ray diffraction (XRD), scanning electron microsc...

We report a simple hard template strategy to prepare multi-shelled titania hollow spheres, which showed enhanced photocatalytic activities in comparison with sphere-in-sphere structures and nanoparticles.
