The preparation of protein doped silica particles is impeded by the difficulty of incorporating proteins within the silica mesostructure under conditions that do not lead to denaturation. Herein, the synthesis of spherical silica particles (diameter 150 nm–550 nm) under protein friendly conditions in a one step proces…

The objective of this work was to verify the influence of the poly(epsilon-caprolactone) PCL concentration in poly(hydroxybutyrate-co-hydroxyvalerate) P(HBHV)/PCL microparticles, prepared by an emulsion/solvent evaporation process, on the release behavior of a drug. Differential Scanning Calorimetry analyses demonstra…
The ionic conductivities and microstructures of Ce 1 − x Yb x O 2 − x ∕ 2 ( x = 0.10 , 0.15, 0.20, and 0.25) with average grain sizes in a range of 0.2 – 3.7 μ m were studied systematically. Nanosized domains were confirmed through detailed studies of transmission electron microscopy. The relationships of the domains,…
Composite ZnO∕CeO2 thin films were grown epitaxially on r-sapphire substrates using the pulsed laser deposition technique. Their crystalline properties were established using x-ray diffraction and showed the ZnO (wurtzite structure) and CeO2 (fluorite structure) layers to be highly textured with the (20−23) and (100)…
The effects of niobium and oxygen content on the mechanical properties, β phase stability and elastic deformation behavior of Ti-Nb-Ta-Zr-O alloys were investigated by employing tensile tests, microstructure observations and XRD analysis. The basic composition of the tested alloys used was Ti-36%Nb-2%Ta-3%Zr-0.3%O (ma…
This chapter covers conventional methods for preparing biological specimens for examination in the scanning electron microscope (SEM). Techniques for handling cells grown in liquid culture, as well as on substrates such as culture dishes, slide culture chambers or agar, are discussed. These methods may be used to proc…
High-resolution synchrotron X-ray diffraction recorded on a collection of\n\t\t\t\t palygorskites with different chemical compositions (obtained by analytical electron microscopy)\n\t\t\t\t permits unambiguous correlation of the crystallographic parameters a (or a sin b if a monoclinic\n\t\t\t\t phase is considered) w…

Macromolecular Crystallography Protocols, now in two volumes, examines major developments that have occurred since publication of the acclaimed first edition nearly a decade ago. Volume 1, Preparation and Crystallization of Macromolecules and Volume 2, Structure Determination, explore recent advances that have acceler…
The Bruggeman formalism provides an estimate of the effective permittivity of a composite material comprising two constituent materials, with each constituent material being composed of electrically small particles. When one of the constituent materials is silver and the other is an insulating material, the Bruggeman…
The hydrothermal reaction of slurries containing MgO and Cp3 alumina has been investigated in situ using energy dispersive X-ray diffraction (EDXRD). A range of temperatures (100, 150, 180 and 240 °C) were studied. Kinetic data for the formation of the hydrotalcite-like Mg–Al layered double hydroxide (LDH) have been d…
A liquid-crystalline octapode, formed by laterally connecting calamitic mesogens to an inorganic silsesquioxane cube through flexible siloxane spacers, is studied using polarized light microscopy, differential scanning calorimetry (DSC) and X-ray diffraction (XRD). The studies are extended to mixtures of the octapode…
An array of FeCo nanotubes has been fabricated in the pores of porous anodic aluminum oxide templates. The morphology, structure, and composition of the nanotube array were characterized by transmission electron microscopy, x-ray diffraction, and atomic absorption spectroscopy. Magnetostatic energy analysis and transm…
The adsorption of H(2) in a cross-linked poly(styrene-co-divinylbenzene) (St-DVB) microporous polymer (BET surface area 920 m(2) g(-1)) is studied by volumetric and gravimetric methods, FTIR spectroscopy at variable temperature (300-14 K) and ab initio calculations. At 77 K the polymer reversibly stores up to 1.3 mass…
Porous silicon oxycarbide (SiOC) ceramics with porosities ranging from 27% to 88% and a cell density higher than 107 cells/cm3 were made from polysiloxane and polymer microbead blends. The polysiloxane and polymer microbeads were compounded directly using a counter-rotated twin-screw extruder with a filamentary die. T…
Using first-principles calculations, we investigate the effect of tube size on optical properties of the zigzag, armchair, and chiral SiC nanotubes. The results indicate that the optical spectra of SiC nanotubes are dependent on the diameter and chirality, and that optical anisotropy is observed for different light po…
The syntheses and structural elucidations of three different cobalt complexes of m-benziphthalocyanine are reported; both Co(II) and Co(III) complexes can be generated, and the ring undergoes partial oxidation upon metalation with Co(OAc)2x4H2O.
Consistent particle properties are an important goal for industrial batch crystallizations. Several control strategies, from unseeded linear cooling to seeded supersaturation control, were evaluated for the cooling crystallization of glycine. Particle properties were assessed in-line, facilitating investigations of pr…
Hydrothermal synthesis of beta-Ni(OH)(2) was performed inside uniform carbon-coated nanochannels of an anodic aluminium oxide film. The time course of crystal formation and growth of Ni(OH)(2) in such one-dimensional nano space was observed using transmission electron microscopy (TEM), and the changes in the number an…
