utilization of the new compatibilizers to improve matrix/filler interface adhesion and also, nanoparticles to improve the properties of wpc products have always been of interest to researchers. in this study, the effect of oxidized polypropylene in solution phase as a comptibilizer and nanoclay particles on the physical and mechanical properties of wood fiber reinforced polypropylene composite ...

this study was devoted to the development of pulp luffa cclindrica and its characterization paper (annual plant fiber of the family cucurbitaceae). baking at soda helps to achieve a high level of delignification (kappa ≤ 10) and high yield (≈ 67%).the beatability stack valley is comparable to refined wood fibers, the fibers develop a normally time with good hydrophilic properties without excess...

s: Soda-anthraquinone (soda-AQ) alkaline sulfiteanthraquinone (AS-AQ) and ASAM (alkaline sulfiteanthraquinonemethanol) cooking of southern cattail whole stem and bark from Sudan was carried out under different conditions and pulps with acceptable to good screened yields and very good mechanical properties were attained. The southern cattail whole stems gave satisfactory mechanical properties wi...

stem cell research has obtained much prominence in recent years for its therapeutic potential in dealing with serious diseases, many of which are essentially incurable by routine therapies. mesenchymal stem cells with pluripotency and immunomodulatory properties are suitable candidates for tissue engineering and regenerative medicine. today, nanofibrous scaffolds are widely used in tissue engin...

Background and Objectives: Kefiran (Kef) is a water-soluble polysaccharide that can form transparent film however, it is brittle. Therefore, in order to improve the mechanical properties of kefiran film, a mixture with other polymers can be offered. The expansion of mixed systems can propose kefiran and polyvinyl alcohol (PVOH) as a new composite film. Materials and Methods: Solutions of 20 gr...

Human embryonic stem cells (hESCs) possess an immense potential in a variety of regenerative applications. A firm understanding of hESC mechanics, on the single cell level, may provide great insight into the role of biophysical forces in the maintenance of cellular phenotype and elucidate mechanical cues promoting differentiation along various mesenchymal lineages. Moreover, cellular biomechani...

Abstract: Horizontal continuous casting is widely used to produce semi-finished and finished metallic products. Homogeneity in metallurgical characteristics and mechanical properties in such products is of importance. In the present work microstructure and mechanical properties of a horizontal continuous cast pipe have been studied. Microstructural features were investigated by an optical mi...

prior to the design and construction of any fruit harvesting machine it is essential to know the physical and mechanical properties of the trees and of its fruits. an example could be cited as the force needed to overcome. the strength with which the fruit is attached to the stem, in trunk shaker harvesting. in this research the acting forces on the fruit during harvest, including tensile stren...
