We show that disorder-induced interaction between guided modes and a flat band of low-Q radiating modes in planar arrays of dielectric particles can lead to frequency-selective omni-directional scattering of light. This phenomenon is numerically observed in planar arrays consisting of periodically arranged dielectric particles with small randomness in particle sizes. The flat band of low-Q radi...

In this study, the effects of limited hydrolysis and/or high-pressure homogenization (HPH) treatment in acid conditions on the functional properties of oyster protein isolates (OPI) were studied. Protein solubility, surface hydrophobicity, particle size distribution, zeta potential, foaming, and emulsifying properties were evaluated. The results showed that acid treatment led to the dissociatio...

The accuracy and practicality of particle size distribution analysis for rapid screening of urine specimens are assessed. Six hundred urines were subjected simultaneously to routine bacteriological examinations and particle size distribution analysis using a Coulter Counter (ZBI) linked to a C1000 Channelyzer. There was complete agreement in the results of 593 (98.8%) specimens. Characteristic ...

an attempt has been made in this paper to investigate the effect of particle size distribution on coal flotation kinetics. the effect of particle size (ps) on kinetics constant (k) and maximum theoretical flotation recovery (ri) was investigated while other operational parameters were kept constant. the relationship between flotation kinetics constant and theoretical flotation recovery with par...

quantum dots of cds with hexagonal phase were prepared at relatively low temperature (60 oc) and short time by micro-emulsion (o/w) under ultrasound. this study was focused on the particle size distribution and the growth kinetics. the particle size distribution obtained from the optical absorption edge. it was relatively symmetrical with sonication time. in addition, an agreement was observed ...

the distribution of extracellular enzyme activities in particle-size fractions of sediments was investigated in a subtropical mangrove ecosystem. five enzymes involved in carbon (c), nitrogen (n), and phosphorus (p) cycling were analyzed in the sand, silt, and clay of sediments. among these fractions, the highest activities of phenol oxidase (pho), β-d glucosidase (glu), and n-acetyl-glucosimin...
