We reported the effect of boron addition on magnetic properties and structure of CoPt nanoparticles. The CoPt-B nanoparticles were synthesized by means of the polyol process. The magnetic property measurement showed that the CoPt-B sample exhibited a much larger coercivity compared to the sample without B additive at the same annealing temperature. Transmission electron microscopy and energy...

Abstract
Co0.3Zn0.7Fe2O4 ferrites were prepared by ceramic process and sintered 1250oC, 1300oC and 1350oC. The crystal structural, morphological and magnetic properties of ferrite...
We have synthesyzed Cu and Fe- doped TiO2 nanotubes by an anodization method. The electrolyte was composed of ethylene glycol (EG), ammonium fluoride (0.3 % wt NH4F) and deionized water (2% vol H2O) with concentration of the dopants Cu and Fe of 0.5 mM. A constant DC power supply of 50 V was used during anodization with anodizing times of 2 hours. X-ray diffraction (XRD) was used to examined...
(Cr,Nb)TiO2 (CN-T) and (Sc,Nb)TiO2 (SN-T) ceramics were prepared via a solid state reaction process. A single phase of rutile TiO2 was confirmed by X-ray diffraction (XRD). Dielectric properties were investigated over frequency range from 40Hz to 10MHz and temperature range from -70C to 220C. The ceramics showed high permittivities (>1000) with low dielectric losses and frequency-stablity....
Method for fabricating a free standing film of colloidal photonic crystal (CPC) has been studied. The CPC films were previously fabricated by drop-coating monodisperse polystyrene nanoparticles on agarose hydrogel. The water-based medium in these CPC films was not long-term stable and the changing of air-humidity resulted in the variation of their optical properties. To sustain the optical...
Leptospirosis is an infectious disease caused by pathogens of the genus Leptospira. This
disease becomes a wide-spreading problem in tropical areas including Thailand. A method of
detection which is used nowadays is microscopic agglutination test (MAT) but its detection limit
is so high that it cannot be used to detect pathogens in low concentration samples. To develop
a new method...
