Non-hollow In(2)O(3) particles with hexagonal rod- and disk-shapes are generated from the calcination of porous CPPs; however, elongated hexagon-, ellipsoid-, and rod-shaped hollow In(2)O(3) particles are formed from the calcination of non-porous CPPs.

The results of the initial experimental studies involving the scattering of ultrasonic signals from canonical and nonanonical shaped suspended particles with known elastical qualities are reported. These results have formed the basis for the development of a numerical model for ultrasound propagation through low-concentration suspensions of sand particles.

Analysis of needle-shaped particles of cellobiose octaacetate (COA) obtained from vacuum agitated drying experiments was performed using three particle size analysis techniques: laser diffraction (LD), focused beam reflectance measurements (FBRM) and dynamic image analysis. Comparative measurements were also made for various size fractions of granular particles of microcrystalline cellulose. Th...

We have examined a salt-soluble, transcriptionally competent gene-enriched fraction of chicken erythrocyte chromatin and compared it to bulk chromatin using the unique microanalytical capabilities of Electron Spectroscopic Imaging (ESI). The salt-soluble fraction is enriched 48 fold in beta-globin gene sequences and is also enriched in histones that are post-synthetically modified, including ac...

Dandruff is a prominent scalp problem caused by the growth of fungus Malassezia furfur, potentially cascading into dermal inflammation, itching, and tissue damage. The present work outlines a detailed analysis of the treatment of scalp infection using silver nanomaterials (Ag NMs), and focuses on biocidal activity owing to manipulation of size, shape, and structure. Monodisperse silver spherica...

A cadmium tetrahydroisoquinoline dithiocarbamate (DTC) complex has been used as single-source precursor for the synthesis of highly faceted hexadecylamine (HDA) capped CdS nanoparticles. Hexagonal and close to cubic shaped particles with distinct lattice fringes are visible in the high resolution transmission electron microscopy images. Crystalline particles in the shape of a hexagon are clearl...

The presence of spherical or rod-shaped electron-dense particles was noted within the mitochondrial cristae of Physarum polycephalum plasmodia. When sporulation was stimulated by starvation and subsequent illumination it was found that the numbers of such particles present per mitochondrion increased during the starvation phase, reaching a maximum after about 4 days, and then decreased rapidly ...

Lymphocytic choriomeningitis (LCM) virus was observed by electron microscopy in thin sections of infected tissue cultures. The particles were pleomorphic and varied greatly in size. The smaller particles (50 to 200 nm) appeared to be spherical, whereas the largest (over 200 nm) were often cup-shaped. All particles contained one to eight or more electron-dense granules which were removed by ribo...

A general method is presented for computing the motions of hydrodynamically interacting particles in various kinds host fluids arbitrary Reynolds numbers. The applicable to dispersions shaped active and passive particles.

We introduce the concept of the equiphase sphere for light scattering by nonspherical dielectric particles. This concept facilitates the derivation of a simple analytical expression for the total scattering cross section of such particles. We tested this concept for spheroidal particles and obtained a bound on the minor-to-major axis ratio for the valid application of this technique. We show th...
