recently, the demands for the production of many different types of plastic wastes are greatly growing that subsequently, lead to the serious challenges in environmental considerations. since, these materials are rarely resolved by microorganisms, hence, their recycling to the useful materials is crucial. in the present study, we used a solution electrospinning technique to synthesize nano/micr...

the study describes the synthesis and characterization of zinc(ii) minoxidil nanocomposite (1). the reaction between zinc(ii) acetate, minoxidil, {c9h15n5o=minoxidil=(2,4-diamino-6-piperidine-1-yl) pyrimidine n-oxide)} as a ligand and ki as bridging agent, in methanol at 60°c leads to the formation of nano-sized zn(ii) minoxidil nanocomposite, 1. characterization of (1) was carried out by eleme...

in order to reduce the operating temperature of solid oxide fuel cells (sofcs), novel electrolyte materials based on ceo2 and baceo3 are being developed in the scientific realm. in this context, we propose a new methodology for preparing the nano-ceramic composite materials such as bace0.9gd0.9o3-δ – ce0.9gd0.9o2-δ (bcgo–cgo) and bace0.8sm0.2o3-δ – ce0.8sm0.2o2-δ (bcso – cso) as possible elec...

regeneration and engineering of functional new tissues containing the neural network have great importance. progression of neural network into the dental tissue has a crucial role in dental tissue regeneration. in the present study polymer-ceramic blended scaffolds containing different weight percentages of carbon nanotube in poly caprolactone nanofiber matrix were fabricated. morphological, me...

The paper presents novel structures of Nano gas sensor arrays by using ZnO and doped with aluminum . ZnO Nanomaterial are successfully prepared using sol-gel technique . These include, similar and dissimilar structures. All used sensors are composed of zinc oxide doped with aluminum at different concentrations for dissimilar structures, and with the same concentration for similar structures. Th...

We show by a combination of computer simulation and experimental characterization guided self-assembly of coherent nano-precipitates into a mesocrystal having a honeycomb structure in bulk materials. The structure consists of different orientation variants of a product phase precipitated out of the parent phase by heterogeneous nucleation on a hexagonal dislocation network. The predicted honeyc...
