Silica (SiO2) aerosol gels were formed via Brownian aggregation of silica nanoparticles in a closed reaction chamber. A sudden and quick detonation reaction of pyrophoric silane (SiH4) with either oxygen or nitrous oxide created silica nanoparticles

The morphological features of a series of high-density polyethylene (HDPE) blown films were studied using transmission electron microscopy, small-angle X-ray scattering and infrared dichroism. An orthogonally-oriented, dual crystalline texture was fo

Using small-angle x-ray (SAXS), neutron (SANS), x-ray diffraction and light scattering, we study the structure of colloidal silica and carbon on length scales from 4 Å < q −1 < 107 Å where q is the magnitude of the scattering vector. These materi

Carbon blacks (CB) demonstrate varied structural features on length scales from angstroms to micrometers. Widely used as fillers in polymers, carbon blacks improve the mechanical and electrical properties of the host material. In general, CB is a low

Linear low-density polyethylene (LLDPE) blown films fabricated under two different processing conditions, namely a non-stalk bubble configuration and a stalk bubble configuration, were investigated. Morphological characterization was performed using

Three different water-alcohol cosolvent systems were used to assemble mesoporous molecular sieve silicas with wormhole framework structures (previously denoted HMS silicas) from an electrically neutral amine surfactant (S{degree}) and a silicon alkox

We use neutron reflectivity to study the effects of harsh environments on the composition and structure of Ta2N films. We investigated samples with a 700 A Ta2N layer, annealed in vacuum, hydrogen, and air, in an attempt to simulate the effects of ag

Nanostructured particles exhibiting well-defined pore sizes and pore connectivities (1-, 2-, or 3-dimensional) are of interest for catalysis, chromatography, controlled release, low dielectric constant fillers, and custom-designed pigments and optica

Small-angle X-ray scattering (SAXS) and transmission electron microscopy image analysis experiments on a series of commercially available carbon blacks verify recent computer modeling results on scattering by mass fractal aggregates of globular parti

Particle size distributions determined by small-angle X-ray scattering (SAXS) and transmission electron microscopy (TEM) are investigated for samples of interacting hard spheres. Polydispersity in the samples is determined from the SAXS data by fitti
