Background: The worldwide medicine research is dedicated towards improvement of patients’ health and diseased state. The use of nanotechnology is an upcoming area which is at present, is highly focused in the filed of medicine. Continuous studies in the area have given rise to the development of a novel field called “nanomedicine” which mainly aims to open new perspective of treatments and increasing therap Read More

Background: Recently it was for the first time found by us, that completely insulating Halloysite nanotubes significantly enhance electrical conductivity of PEDOT/PSS films by simply mixing. Based on this interesting finding highly porous and conductive PEDOT/PSS films hybridized with the Halloysite nanotubes (HNTs) were prepared. The highly porous morphology of the hybrid films would hinder thermal conduction, res Read More

Background: Fuel cells have a very low emission of greenhouse gases such as CO2, SOx etc with high efficiencies and are non-polluting energy sources. One of the current challenges is to develop inexpensive and efficient oxygen reduction reaction (ORR) materials. Extensive research has been conducted to develop platinum (Pt) loaded carbon nanomaterials for ORR applications. However, the literature is rife with inconsist Read More

Background: The separation of enzymes from the bio-product medium constitutes a significant part of total process cost. Therefore, it is of crucial importance that the separation processes for enzymes be specially developed. In this study, the advantages of cross-linked enzyme aggregates (CLEAs) and magnetic iron oxide nanoparticles (MIONPs) have been combined in magnetic CLEAs matrix. Methods: MIONPs were produc Read More

Background: Recently, hydrophilic carbon-coated magnetite (Fe3O4/C) has been prepared and applied in adsorption and separation sciences. Although there have been some works on preparation and application of Fe3O4/C in adsorption and separation sciences, little work has been carried out on protein adsorption and desorption on Fe3O4/C. Herein, the present work investigated the equilibrium and kinetics of prote Read More

Background: In the last decade, Fe3O4 nanoparticles have been intensively investigated for medical applications. Up now, various chemical methods have been applied for their preparation. Although, these methods have been improved in the recent years, however, higher temperature (100-300 oC), toxic and expensive precursors and limited controllability of particle morphology and size still the challenges. As an altern Read More

Background: ZnO-based varistors are used as surge protectors in electrical circuits. Nonlinear polymer composites are attractive because of their potential applications in low voltage varistors. The aim of this research is to study nonlinear behavior in a new composite containing ZnO, polythiophene and polyethylene. Methods: Sample disks consist of 70 wt% ZnO and 30 wt% polymer matrixes were prepared using the h Read More

Background: In this study, nanoemulsion based gel formulation of acyclovir was prepared in order to increase its topical effectiveness and target the disease site, which is the foremost limitation associated with the topical marketed formulations of acyclovir. Methods: In this study, nanoemulsion based gel formulation of acyclovir was prepared in order to increase its topical effectiveness and target the disease site, Read More

Background: Different methods of fertilization including chemical (chemical fertilizer such as urea), biological (microbial inoculums) and nano (nutritional elements at the nano level) fertilization are used for providing plants with their essential nutrients under different conditions including stress. With respect to the properties of nutrients at the nano level, the method of nano fertilization, which is a new era in the research, Read More

Background: Materials with features such as high transparency and nonlinearity in a wide range of infrared wavelengths can be used in the manufacture of optical fibers. Amongst the materials that are used in the manufacture of optical fibers, chalcogenide compounds are the key materials in the infrared wavelength range. This paper presents a new hexagonal nanostructured photonic crystal fiber based on chalco Read More

Background: Among some of the widely adopted modification methods, metal ion doping in TiO2 based materials is believed to be helpful to retard recombination of photogenerated electronhole pairs. The combination of indium and gadolinium in synthesizing In-Gd co-doped TiO2 is a new approach. The effects of calcination temperature on characterizations and photocatalytic activity of 3%In-0.1%Gd-TiO2 photocatalyst w Read More

Background: Amorphous NiAl alloys, whose atomic arrangement is disordered, have attracted a lot of attention due to their unique physical properties, such as high mechanical strength and hardness, high toughness, low friction, good corrosion resistance, and minimal shrinkage. The alloys have excellent corrosion resistance at high temperature and thus are often used in blade coatings. Nanoimprinting lithography (NI Read More

Background: Microfluidic chip, also known as lab-on-chip, is recognized as one of the most important advanced science and technology in twenty-first Century. Due to high chemical specificity and high information content, SERS can be used in a microfluidic channel to achieve simultaneous monitoring of composition of multiple analytes. In this paper, we present a simple method to prepare SERS substrate inside a microfluidi Read More
