Abstract To clarify the effect of Hindered amine light stabilizer (HALS) on ultraviolet (UV) aging behavior asphalt binder, evolution history and characteristics UV induced micro-structure modified were characterized. Scanning Electron Microscope (SEM) Atomic Force (AFM) used to analyze microscopic morphology stabilizer-modified during aging. By defining in joints by UV, identification classifi...

Aerosol solvent extraction system (ASES) was used to prepare micro-particle of acetaminophen by supercritical carbon dioxide as an anti-solvent. Experiment was carried out at various temperatures, pressures, solvents and investigated the effects of these parameters on particle size, size distribution and morphology by SEM and laser diffraction particle size analyzer. It seems that the choice of...

Abstract The micro-arc oxidation protective film has been prepared on the surface of Mg-9%Gd -2%Y-3%Nd-0.7%Zr alloy by using microarc technique “step step depressurization”. microstructure magnesium substrate and were measured OM, SEM XRD, properties evaluated electrochemical test thickness morphology. results show that discontinuous network multiple eutectic phases are distributed in grain bou...

AIM To observe the morphology of the root canal system of the maxillary first molar mesiobuccal root using micro computed tomography and compare it to current canal classifications. METHODOLOGY Twenty mesiobuccal roots were resected from randomly selected extracted human maxillary first molar teeth and prepared for scanning using a SkyScan micro CT scanner (SkyScan 1172 X-ray microtomograph, ...

To understand the physical behavior and migration of cancer cells, a 3D in vitro micro-chip in hydrogel was created using 3D projection printing. The micro-chip has a honeycomb branched structure, aiming to mimic 3D vascular morphology to test, monitor, and analyze differences in the behavior of cancer cells (i.e. HeLa) vs. non-cancerous cell lines (i.e. 10 T1/2). The 3D Projection Printing sys...

It is now clear in many species that male and female genital evolution has been shaped by sexual selection. However, it has historically been difficult to confirm correlations between morphology and fitness, as genital traits are complex and manipulation tends to impair function significantly. In this study, we investigate the functional morphology of the elongate male intromittent organ (or pr...
