Electrospinning is a simple and versatile technique that relies on the electrostatic repulsion between surface charges to continuously draw nanofibers from a viscoelastic fluid. Electrospinning can generate nanofibers with a number of secondary structures. Surface and/or interior of nanofibers can be functionalized with molecular species or nanoparticles during or after an electrospinning proce...
in this work, we report synthesis of surface modified superparamagnetic iron oxide nanoparticles (spion) by co-precipitation method using feso4.7h2o and fe2(so4)3.5h2o as precursors and trisodium citrate dihydrate as surfactant. surface modification of the as prepared samples was performed in pot by sol-gel precipitation method using tetraethoxysilane (teos). the structure, morphology, and magn...
background: development of tissue engineering and regenerative medicine has led to designing scaffolds and their modification to provide a better microenvironment which mimics the natural niche of the cells. gelatin surface modification was applied to improve scaffold flexibility and cytocompatibility. methods: plla/pcl aligned fibrous scaffold was fabricated using electrospinning method. adscs...
Several surface modification techniques such as ion implantation, surface laser melting, have been employed to improve pitting corrosion resistance of stainless steel. Electropolishing is a technique in which the surface roughness is eliminated through a selective electrochemical dissolution. The effect of electropolishing on pitting corrosion of 304 stainless steel (SS) was investigated employ...
