Porous polymer monoliths onto which were grafted a thermoresponsive copolymer, poly(2-(2-methoxyethoxy)ethyl methacrylate (MEO2MA)-co-oligo(ethylene glycol) (OEGMA)), synthesized by the two-step atom transfer radical polymerization (ATRP) method. The copolymer-grafted characterized elemental analysis, scanning electron microscopy, and mercury intrusion porosimetry. They further used as stationary phase for all-aqueous high-performance liquid chromatography (HPLC). chromatograms of three...
In this paper, the coupling effect of multiphysical fields droplet migration is deeply studied by constructing a physical model with fields. Digital holographic interferometry and particle image velocimetry are used to simultaneously measure temperature velocity mother liquor in process for first time. Due advancements measuring, zero-velocity region also where thermal wake appears, four vortexes appear off-axis behavior double-droplet found. The aim work analyze relationship fields, so as...
Abstract A capillary electrophoretic assay for determining aloe‐emodin (AE), methyl p ‐coumarate (MC), and 3,4‐dihydro‐6,8‐dihydroxyl‐[(3s)‐2′‐acetyl‐3′‐hydroxyl‐5′‐methoxy‐benzyl]‐isocoumarin (DDI) in Aloe vera has been developed. Baseline separation was achieved within 15 min using a running buffer of 20 mm borax containing 10% (v/v) acetonitrile at pH 10.5. linear relationship between the peak area concentration analytes found ranges 5–500, 10–1000 2–1000 µg/mL AE, MC DDI, respectively,...
The interactions between basal plane dislocations (BPDs) and threading screw edge (TSDs TEDs) in hexagonal SiC have been studied using synchrotron white beam x-ray topography (SWBXT). TSDs are shown to strongly interact with advancing while TEDs do not. A BPD can cut through an individual TED without the formation of jogs or kinks. BPDs were observed be pinned by creating trailing dislocation dipoles. If these dipoles orientation segments cross-slip annihilate also potentially leaving...
