This research explains the melt spinning of bicomponent fibers, consisting of a conductive polypropylene (PP) core and a piezoelectric sheath (polyvinylidene fluoride). Previously analyzed piezoelectric capabilities of polyvinylidene fluoride (PVDF) are to be exploited in sensor filaments. The PP compound contains a 10 wt % carbon nanotubes (CNTs) and 2 wt % sodium stearate (NaSt). The sodium s...
This study describes development of a novel controlled drug release system for multiple drugs, it consisted of Chitosan nanoparticles/PCL composite electrospun nanofibers with core-sheath structures. Two model agents' rhodamine B and naproxen were successfully loaded in the core and sheath region respectively. The behavior of these two agents demonstrated a good controlled release and temporali...
از جمله معروفترین آنتی بیوتیکهای ضدسرطان، می توان به آدریامایسین دانومایسین و اکتینومایسین d اشاره کرد. این داروها در معالجه سرطان از طریق شیمی درمانی مودر استفاده قرار می گیرند. هدف اصلی این داروها در سلول، مولکول dna است . از آنجا که مولکول dna در داخل هسته سلول به صورت برهنه و آزاد نیست بلکه در اتصال با ترکیبات دیگری مثل پروتئین های هسیتونی و غیرهیستونی می باشد، میان کنش این داروها با پروتئی...
we report the fabrication of pure CeO2, ZnO and SiO2 deposited CeO2 hybrid core-shell nanoparticles by simple and cost effective co precipitation method. The as synthesized samples were characterized by various experimental techniques such as XRD (X-ray diffraction), FTIR (Fourier Transform Infrared Spectroscopy) and HRTEM (High Field Transmission Tunneling Microscopy) measurements. XRD results...
In this paper, a semiconducting photonic nanostructure capable of wide range absorption and tunable optical resonance has been designed with a proposed theoretical optimization model. The design consists of ZnO/CdS core-shell nanowire arrays as well as multilayer thin films that act to absorb incident electromagnetic (EM) waves over a broad frequency range. Theoretical, as well as numerical, st...
