A temperature-responsive poly(N-isopropylacrylamide-co-N,N'-methylenebisacrylamide) [poly(NIPAAm-co-BIS)] monolith was prepared via a free-radical polymerization technique using an aqueous redox initiator in solution at -12°C. The effect of the % T (total monomer concentration/100 mL) and % C (cross-linker concentration/100 mL) on the visual form was(More)
SrFe12O19/Ni(0.5)Zn(0.5)Fe2O4 composite ferrite nanofibers of diameters about 100 nm with mass ratio 1:1 have been prepared by the electrospinning and calcination process. The SrFe12O19/Ni(0.5)Zn(0.5)Fe2O4 composite ferrites are formed after calcined at 700 degrees C for 2 hours. The composite ferrite nanofibers are fabricated from nanosized(More)
A thermo-responsive and macroporous monolithic cryogel was directly prepared by in situ free-radical redox cryo-polymerization in a stainless steel chromatographic column (100 mm × 4.6mm i.d.) using N-isopropylacrylamide (NIPAAm) as functional monomer and PEG-20,000 as porogen at -12°C. The internal morphology of resulting monolithic cryogel was estimated(More)
The nanocomposite SrFe(12)O(19)/Ni(0.5)Zn(0.5)Fe(2)O(4) ferrite aligned hollow microfibers with the hollow diameter to the fiber diameter estimated about 3/5 have been prepared by the gel precursor transformation process. The nanocomposite binary ferrites with different mass ratios are formed after the precursor calcined at 900°C for 2h, fabricating from(More)
