“…Details of the instrument for the SANS experiment were provided elsewhere [21]. A data reduction program, GRASP [22], was applied to correct all the scattering data for an empty cell as the background, noise of the dark electronic current, the detector efficiency, and transmission of the samples.…”

A series of Mn x Fe 3−x O 4 (0 ≤ x ≤ 1) nanoparticles was successfully synthesized via a simple coprecipitation method. The starting material was a natural magnetite purified from local iron sand. Crystallite nanoparticles were produced by drying without using a high calcination temperature. Rietveld analysis of the X-ray diffractometry (XRD) data for all samples demonstrated that the Mn ions partially substituted the Fe ions in the spinel cubic structure of the Fe 3 O 4 to form Mn x Fe 3−x O 4 phases. We applied two lognormal spherical and single mass fractal models to the analysis of the small-angle neutron scattering (SANS) data and revealed that the primary Mn x Fe 3−x O 4 particles ranged in size from 1.5 to 3.8 nm and formed three-dimensional Darminto

“…A 36-m SANS spectrometer was used to investigate the primary and secondary particles as well as the fractal structure of Fe 3 O 4 nanoparticles. The detailed SANS measurements have been given elsewhere [54,60]. The two-lognormal analysis was also performed to investigate the clustering effect of the magnetic fluid and hydrogel [55,57].…”

Nanoparticles of Fe 3 O 4 have been successfully synthesized using a simple coprecipitation technique from natural iron sands, employing HNO 3 and NH 4 OH as dispersing and precipitating agents, respectively. The substitution of Fe with Mn to result in Fe 3x Mn x O 4 (0 ≤ x ≤ 3) was conducted to control the magnetic strength of this nano-sized spinel powder. It is shown that magnetic properties depend not only on the particle size and Mn doping but also on the particles clustering. The applications for magnetic fluids, gels, and coating are extensively described. Meanwhile, the spinel MgAl 2 O 4 nanoparticles have also been prepared by the same simple method from commercial starting materials. This powder was used as a nano-reinforcer of Al-matrix composites. In addition, MgAl 2 O 4 micro-sized powder forming a thick layer was successfully grown by electroless plating on the interface of matrix-filler in Al/SiC composites. The strengthening of mechanical properties with respect to the varying uses of these MgAl 2 O 4 powders is discussed.

“…SANS experiments were carried out on SMARTer, the 36 meter SANS BATAN spectrometer at neutron scattering laboratory (NSL) in Serpong, Indonesia. The detail of the SANS BATAN spectrometer was described in other references [14][15]. Each sample was measured at two detector distances, 1.5 and 3 m, to cover a momentum transfer Q range from 0.02 to 0.25 Å -1 with the neutron wavelength λ of 3.9 Å.…”

Small-angle neutron scattering (SANS) measurements on 0.3M sodium dodecyl sulfate (SDS) micellar solutions have been performed in the presence of n-alcohols, from ethanol to decanol at different alcohol concentrations, 2-10 wt%. The ellipsoid micellar structure which occurred in the 0.3M SDS in aqueous solution with the size range of 30-50 Å has different behavior at various hydrocarbon chain length and concentration of alcohols. At low concentration and short chain-length of alcohols, such as ethanol, propanol, and butanol, the size of micelles reduced and had a sphericallike structure. The opposite effect occurred as medium to long chain alcohols, such as hexanol, octanol and decanol was added into the 0.3M SDS micellar solutions. The micelles structure changed to be more elongated in major axis and then crossed the critical phase transition from micellar solution into liquid crystal phase as lamellar structure emerged by further addition of alcohols. The inter-lamellar distances were also depending on the hydrocarbon chain length and concentration of alcohols. In the meantime, the persistent micellar structures occurred in addition of medium chain of nalcohol, pentanol at all concentrations.
