Magnetic exchange bias effect in Manganese Oxide Core-Shell Nanoparticles fabricated by inert gas condensation technique

Khan F.A., Bah M., Shah S.I., Department of Physics, Bangladesh University of Engineering and Technology(BUET), BD

Manganese oxide core-shell nanoparticles are fabricated by inert gas condensation technique. The as deposited samples are found to be amorphous in nature with random distribution of clustered particles. X-Ray Diffraction (XRD) and High Resolution Transmission [...]

Monodisperse Thermo-responsive Composite Microgels with Core-shell Structure based on Au@Ag Bimetallic Nanorod as Core: Fabrication and Application in SERS Substrate

Dong X., Zha L.S., Donghua University, CN

In summary, monodisperse Au@Ag bimetallic nanorod is encapsulated by crosslinked poly(N-isopropylacrylamide) (PNIPAM) to produce thermo-responsive composite microgel with well-defined core-shell structure (Au@AgNR@PNIPAM microgel) by seed-precipitation polymerization method using butenoic acid modified Au@AgNRs as seeds. Their [...]

Hollow core-shell structured mesoporous MWCNT/carbon nanofiber composites by electrospinning and silica template as counter electrodes for dye-sensitized solar cells

Park S.H., Kim B-K., Lee W.-J., Chonnam National University, KR

The multi-walled carbon nanotube (CNT)-embedded carbon nanofibers with hollow core/highly mesoporous shell stucture (CNT/Meso-HACNF) are prepared by concentric electrospinning using poly(methyl methacrylate) (PMMA) as a pyrolytic core precursor with either CNT/polyacrylonitrile (PAN) or fumed silica [...]
