relationship of sorghum kernel size to physiochemical milling pasting and cooking properties
Food Research International, 2002Co-Authors: Jeffrey F Pedersen, D R SheltonAbstract:Effects of kernel size on grain sorghum [Sorghum bicolor (L.) Moench] quality were studied in an experiment designed to separate effects of kernel size from seedlot. The study utilized three sieve fractions of varying kernel diameter (>3.35, >2.80 and >2.36 mm) from six seedlots. Chemical composition, physical characteristics, milling characteristics, pasting properties, and cooking qualities were determined for each kernel size fraction. Large kernels lost less relative mass during 1 min of decortication, were higher in protein concentration, and lower in ash. Milling yields were higher from large kernels, and flour from large kernels had higher water absorbance, brighter white color, and Larger Particle size. Kernel size effects on Rapid Visco Analyzer (RVA) properties were not consistent. These results suggest that within the sorghum seedlots studied, an increase in kernel size is associated with an increase in sorghum quality as defined by the parameters measured in this study.

Particle size effects and surface anisotropy in fe based granular films
Journal of Applied Physics, 1998Co-Authors: Chen Chen, O Kitakami, Yutaka ShimadaAbstract:Structure and magnetic properties of Fe/SiO2 and Fe/Al2O3 granular films were studied in the Particle size (d) range of 1–50 nm. The coercivity (Hc) shows a maximum around 600 Oe at the Particle size dm≈18 nm, and then decreases in the Larger Particle size range for both Fe/SiO2 and Fe/Al2O3 systems at room temperature. A relation of coercivity, Particle size, and temperature was built by using the Neel–Brown theory and the Stoner–Wohlfarth model basically. The experimental results were successfully fitted by assuming that the α-Fe Particles possess uniaxial surface anisotropy Ks≈0.4 erg/cm2.Structure and magnetic properties of Fe/SiO2 and Fe/Al2O3 granular films were studied in the Particle size (d) range of 1–50 nm.

nucleation and crystal growth of nanocrystalline anatase and rutile phase tio2 from a water soluble precursor
Crystal Growth & Design, 2010Co-Authors: Nichola M Kinsinger, Ashley Wong, Dongsheng Li, Fabian Villalobos, David KisailusAbstract:Titanium dioxide (TiO2) has been widely used as an advanced semiconductor and as a white pigment for many years. In recent years, TiO2 has gained much more interest for its semiconducting properties for use as photocatalytic and photovoltaic materials. Understanding the fundamental nucleation and growth mechanisms is crucial to controlling microstructure and properties for these applications. Nanosized rutile and anatase Particles were synthesized from a water-soluble titanium(IV) precursor using a hydrothermal method. The impact of various hydrothermal conditions on the formation, phase, morphology, and grain size of the TiO2 products was investigated using XRD, TEM, and FTIR. At near neutral pH, aggregated rutile rods are formed. By increasing the alkalinity of the reaction medium, the anatase phase was favored and, as expected, Larger Particle sizes resulted from longer duration reactions. The effects of reaction conditions are discussed with respect to coordination chemistry and coarsening mechanisms.
