To fully understand the polymer-filler interfacial interaction mechanism, we use a coarse-grained molecular dynamics simulation to mainly investigate the interfacial dynamic properties by tuning the polymer-filler interaction, temperature, chain length, volume fraction of filler, and size and shape of filler. The polymer beads around the filler exhibit an obvious layering behavior and a gradien...

This study was designed to determine the optimum conditions of three different factors (mixing time, mixing temperature, and tube size) in reduction of cholesterol in milk using immobilized beta-CD beads. Immobilized beta-CD glass beads were prepared at different conditions of silanization and beta-CD immobilization reactions. In result, the glass beads (diameter 1 mm) at 20 mM 3-isocyanatoprop...

A new procedure is described to deposit paramagnetic beads on surfaces to form microscopic agglomerates. By using surface-modified beads, microscopic structures with defined biochemical activity are formed. The shape and size of agglomerates were characterized by scanning electron microscopy (SEM), and the biochemical activity was mapped with scanning electrochemical microscopy (SECM). This app...

The purpose of this work was to develop a multiparticulate system exploiting the pH-sensitive property and biodegradability of calcium alginate beads for intestinal delivery of ceftriaxone sodium (CS). CS was entrapped in beads made of sodium alginate and sodium carboxymethylcellulose (CMC), acacia, HPMC K4M and HPMC K15M as drug release modifiers. Beads were prepared using calcium chloride as ...

Effects of temperature the tetraethylammonium hydroxide (TEAH)/urea/cellulose solution on viscosity, surface tension, and size cellulose beads were investigated. Hardwood bleached kraft pulp (HwBKP) was used as a sauce dropping method utilized to fabricate beads. Temperature varied from 30℃ 50℃. When increased, viscosity decreased while tension increased. In addition, increasing resulted in inc...

In the present work, fine grinding of limestone was performed by using a super centrifugal mill (SC-mill), type bead mill. The feed sample contained particles below 75 μm in size ground crusher with slurry density 30 mass%. eff ects operational conditions including rotor speed, time, size, and mass beads on grindability were investigated, as well wear beads. evaluated through products 1 measure...

Microbeads that are both paramagnetic and fluorescently labeled are commercially available in colors spanning the visible spectrum. Although these commercial beads can be bright, polydispersity in both size and fluorescent intensity limit their use in quantitative assays. Very recently, more monodisperse beads have become available, but their large size and surface properties make them less tha...

Background: Polymethylmethacrylate antibiotic impregnated beads can be an effective treatment for chronicosteomyelitis or an adjuvant in the treatment of open fractures. It remains unclear however whether the beads causelong-term adverse events if not removed. The purpose of this study was to determine if removal of antibiotic beads wasrequired in order to avoid long term comp...

Laser diffraction (LD) has been recognized as a method for estimating particle size distribution. Here, a recently developed quantitative LD (qLD) system, which is an LD method with extensive deconvolution analysis, was employed for the quantitative assessment of protein particles sizes, especially aimed at the quantification of 0.2-10 μm diameter subvisible particles (SVPs). The qLD accurately...
