Phospholipid bilayers, 40 A thick, were generated as electron microscope substrates by submerging copper grids overlaid with holey plastic through a lipid monolayer on a water surface. Previously formed proteoliposomes containing single-particle memb

Core−shell polymer microspheres have been prepared by a two-step precipitation polymerization. These microspheres consist of 3.2 μm polydivinylbenzene-55 (DVB55) cores coated with ∼0.4−0.9 μm wide shells composed of poly(DVB55-co-EDMA), a ran

The role of hydrophobic particles in mineral oil-based defoamers was investigated by fluorescence labeling and microscopy. Defoamer emulsion droplets in water adhere to the air/water interface to become lenses that nucleate bubble coalescence. Fluore

Colloidal silica modified with a hydridosilsesquioxane (HSiO3/2) layer reacted with Karstedt's catalyst, bis(1,3-divinyl,1,1,3,3-tetramethyldisiloxane) platinum(0), to give catalytically active surface-bound platinum nanoparticles with an average dia

SUMMARY A method to calibrate current density ratios for the determination of specimen thickness is presented. This method uses a tilt series from a single noncrystalline specimen to create different thicknesses; these are used to generate data point

The novel, proinflammatory cytokine endothelial monocyte-activating polypeptide-II (EMAP-II) was first found in tumor cell supernatants. EMAP-II is closely related or identical to the p43 auxiliary protein of the multisynthase complex, which is invol

Scanning transmission X-ray microscopy (STXM) is being developed as a new tool to study the surface chemical morphology and biointeractions of candidate biomaterials with emphasis on blood compatible polymers. STXM is a synchrotron based technique wh

Scanning transmission X-ray microscopy (STXM) has been used to study the chemical composition and morphology of spontaneous and artificially generated polymer microstructures. Examples include quantitative studies of the internal structure of polymer
