The aim of this study was to synthetize porous three-dimensional composites, similar with natural bone structure, for using it in tissue engineering. The new composites prepared by freeze-drying of composite gels consist of a mineral phase nanohydroxyapatite and an organic phase type I fibrillar collagen and silk sericin, the latter acting as a glue-like protein that serves as an adhesive, for ...

objective(s):cardiomyocytes have small potentials for renovation and proliferation in adult life. the most challenging goal in the field of cardiovascular tissue engineering is the creation of an engineered heart muscle. tissue engineering with a combination of stem cells and nanofibrous scaffolds has attracted interest with regard to cardiomyocyte creation applications. human adipose-derived s...

aluminum alloys such as al 5083 have primary potential for lightweight structural application in automotive and aerospace industries. this paper addresses the mechanical and tribological properties and corrosion resistance of chromium nitride coatings deposited on al 5083 that can be used for development of applications of aluminum 5083 alloy. the crn coatings of 1 μm thickness were deposited b...

Assessment of genetic diversity and individual relationships in rice (Oryza sativa) germplasm collections seems to be necessary for future rice breeding program. In order to understand genetic relationships of 30 rice genotypes, nine morphological traits, seven physicochemical properties and twelve RAPD primers were used for study of 30 rice genotypes. Among morphological traits, numbe...

Sedimentation in the dune fields of the Sistan Plain of Iran is the result of deposition of fine-grained sediment downstream of the Helmand River. Due to poor adhesion and low moisture content of soil particles, and the strong renowned Levar wind, dune fields mostly of Barchan and Nebkha types are created. This study aims to assess the physical, morphological and mineralogical characteristics o...

In this study, a green composite was produced from Oil Palm Trunk Lumber (OPTL) by impregnating oil palm shell (OPS) nanoparticles with formaldehyde resin. The changes of physical, mechanical and morphological properties of the OPS nanoparticles impregnated OPTL as a result of natural weathering was investigated. The OPS fibres were ground with a ball-mill for producing nanoparticles before bei...
