In this paper, we have proposed a simple method to covalently conjugate biotin to magnetic nanoparticles, which can be targeted to the tumour sites by using pretargeting approach with avidin or streptavidin. Magnetic nanoparticles of manganese ferrite were synthesized by alkaline coprecipitation of ferric chloride hexahydrate, ferrous sulphate heptahydrate and manganese sulphate monohydrate usi...

Manganese ferrite ( Mn ) telah berhasil disintesis dengan metode kopresipitasi pada suhu 60 ℃. dari pasir besi sebagai prekusornya. Tujuan penelitian ini untuk mensintesis dan menganalisis gugus fungsi serta morfologinya. Sampel dibuat memvariasikan NaOH yaitu 3 M, 6 M 9 M. Struktur kristal, morfologi dikarakterisasi X-ray Difractometer (XRD), Fourier Transform Infra Red (FTIR), Transmission El...

A new process combining 4% prestrain, intercritical annealing, quenching, and partitioning (prestrain–IA–Q&P) is used to investigate the effect of tensile number on microstructure mechanical properties medium‐manganese steels. microstructural model built based specimens’ properties. The amount tiny brilliant white carbide particles precipitated in seems grow with stretches. test steel's str...

High strength steels Q690+Q550 were welded using three different welding wires without preheating by gas shielded arc welding process. Microstructural characteristics of weld metals and nucleation mechanism of acicular ferrite were investigated by means of scanning electron microscope (SEM), energy dispersive spectrum (EDS) and transmission electron microscope (TEM). The straight Y-groove test ...

The successive ferrite (α) + pearlite (P) transformations from austenite (γ) have been modeled to predict the intervention of bainite in as-forged medium-carbon manganese steels. The kinetics of the diffusional transformations were calculated based on the classical nucleation-growth theory coupled with the CALPHAD multi-component thermodynamics. The description of growth rate of proeutectoid-α ...

In this work firstly MgFe2O4 nanoparticles were synthesized via a microwave-assisted method. The product was calcinated at 900 ºC for 2h. At the second step zinc oxide shell was synthesized on the ferrite under ultrasonic waves. Properties of the product were examined by X-ray diffraction pattern (XRD), scanning electron microscope (SEM) and Fourier transform infrared (FT-IR) spectroscopy. Vibr...
