Carbon-coated Si/carbon nanotube/graphene oxide (C-Si/CNT/GO) microspheres with a robust core–shell composite structure were successfully fabricated by efficient and scalable spray-drying chemical vapor deposition (CVD) for application as lithium-ion battery (LIB) anode. The amphiphilic GO nanoparticles facilitated the uniform dispersion of Si suppressing CNT aggregation in Si/CNT/GO microspher...

The preparation of different carbon-shell morphology microspheres and controllable surface area via using thermoplastic polymers as carbon source was still a challenge. In addition, the unique structure porous Silica@Carbon (Sil@C) not only can provide larger active site, but also have characteristics high mechanical strength easy modification. Herein, we report simple method to in-situ fixatio...

Herein, core–shell structural SiO2@Cu and SiO2@MoS2 microspheres were prepared using SiO2 as hard core, Cu MoS2 shell. As lubricant additives introduced into base oil (PAO 40), their friction reduction wear resistance investigated in detail. Comparing with onefold additive (SiO2, MoS2), such can improve the tribological behaviors at Hertz contact stress range of 1.26–2.72 GPa (SiO2@Cu reduces u...

Core-shell structured CaCO3 microspheres (MSs) were prepared by a facile, one-pot method at room temperature. The adsorbent dosage and adsorption time of the obtained CaCO3 MSs were investigated. The results suggest that these CaCO3 MSs can rapidly and efficiently remove 99-100% of anionic dyes within the first 2 min. The obtained CaCO3 MSs have a high Brunauer-Emmett-Teller surface area (211.7...

Titania is an important material in modern materials science, chemistry, and physics because of its special catalytic, electric, and optical properties. Here, we describe a novel method to synthesize colloidal particles with a crystalline titania, anatase core and an amorphous titania-shell structure. We demonstrate seeded growth of titania onto titania particles with accurate particle size tun...

the objective of this study was to formulate and evaluate the drug-polymer interaction of mefenamic acid (ma) using two polymers with different characteristics as ethylcellulose (ec) and/or cellulose acetate phthalate (cap). microspheres were prepared by the modified emulsion solvent evaporation (mese). the effect of drug-polymer interaction was studied for each of microspheres. important param...

The coemulsification method suitable for the formulation of microcapsules of n-eicosane coated with a polysiloxane is developed. This method allows to synthesize core-shell microcapsules of paraffin which have the shape of spheres or distorted spheres and are designed for the use as phase change materials. The microcapsules are formed in aqueous phase by the precipitation of n-eicosane together...

The one-step synthesis of nanoscale conjugated microporous polymer (NCMP) capsules is presented by using PMAA microspheres as self-sacrificial templates. Precise control over the morphology, nanostructure and shell thickness makes the NCMPs have a tunable NIR absorption ability and a shape-dependent photothermal conversion efficiency. Upon exposure to 808 nm light, they rapidly generate heat (N...
