The aim of this work is synthesis a novel nanocomposite containing Polylactide (PLA) and polyamide 6 (PA6) reinforced with graphene oxide (GO) poly ethylene-butyl acrylate-glycidyl methacrylate) (PTW) compatibilizer during solvent-based method. For purpose, GO was added to the 0.1, 0.3, 0.5, 0.7 1 phr. Morphology, rheology mechanical properties nanocomposites were studied scanning electron micr...
Abstract Laboratory measurements can determine the potential for geologic materials to generate unstable (seismic) slip, but a direct relation between sliding behavior in laboratory and physical characteristics observable field is lacking, especially phyllosilicate-rich gouges that are widely observed natural faults. We integrated friction experiments with surface topography microscopy demonstr...
The bonding performance between adherend and adhesive depends on two main factors including the surface roughness of bondline thickness adhesive. This paper investigated how substrate influence epoxy joints A36 mild steel substrates using single lap shear (SLS) tests. evaluated performances included strength maximum strain which were fabricated with four different roughnesses three thicknesses ...
Medical image enhancement is one of the most widely used medical processing techniques in domain. Its purpose to improve visual effect and facilitate analysis understanding by human or machine. The Laplace transform Sobel gradient operator are two common ways performing edge detection, sharpening enabling be enhanced. However, each has limitations when isolation. a good detection effect, but it...
Gardenia jasminoides Ellis, a representative for “homology of medicine and food”, can be used to produce pigment edible oil. Here, aqueous enzymatic extraction (AEE) combined with puffing pre-treatment was explored prepare oil from gardenia seeds. Both wet-heating (WP) at 90 °C dry-heating (DP) 1.0 MPa facilitated the release free by AEE, resulting in highest yields (FOY) 21.8% 23.2% within 3 h...
Exploring new ways to acquire niobium resources is essential resolve supply risks, due the fact that, at present, 99% of controlled by only two countries. In present work, a flotation technique was applied separate from low-grade niobite ore. To maximize utilization original ore resources, pre-flotation conducted recover sulfur and eliminate adverse effects sulfide on flotation. The obtained gr...
MgO nanowires were grown by a thermal evaporation method at different N2/O2 gas ratios in order to investigate the effect of oxygen concentration on growth and luminescence properties nanowires. A process was conducted 1000oC under pressure 500Torr. No pure N2 atmosphere. Nanowires formed concentrations above 25% mixture O2 gases. X-ray diffraction analysis showed that had cubic crystal structu...
In this proposal the mechanical properties of natural and synthetic rubbers are studied under different temperatures both real ageing heat treatment conditions. For purpose, tire rubber bearing pad considered as they most governed in respectively. The experimental results confirm that impact temperature is higher on than because ambient aggravate thermal motion changes molecular arrangement oth...
The aim of this study was to investigate the dimensional stability and mold resistance slivers from outer inner layers bamboo treated with alkali solutions at various concentrations. microstructure considerably changed as parenchyma cells collapsed after treatment followed by a drying process. water absorption increased, while decreased, especially for layer bamboo. removed starch in 2% 15% sol...
In this study, solvent-cast polymeric films containing ionic liquid lidocaine/aspirin for transdermal patches were developed. Solvent-cast prepared from two polymers, pectin and Eudragit® NE 30D, by drying the solution in a hot air oven at 70 ± 3 °C 10 h. Glycerin was used as plasticizer. Lidocaine aspirin form loaded into patches. The physicomechanical properties of characterized texture analy...
