This paper gives a comprehensive review about the most recent progress in graphene and graphene oxide based electrochemical sensors and biosensors. Graphene, emerging as a true 2-dimensional material, has received increasing attention due to its unique physicochemical properties (high surface area, excellent conductivity, high mechanical strength, and ease of functionalization and mass production). The application […]
Buckling analysis of a functionally graded (FG) nanobeam resting on two-parameter elastic foundation is presented based on third-order shear deformation beam theory (TOSDBT). The in-plane displacement of TOSDBT has parabolic variation through the beam thickness. Also, TOSDBT accounts for shear deformation effect and verifies stress-free boundary conditions on upper and lower faces of FG nanobeam. […]
In this study, the La3+/Co3O4 nanoflowers were synthesized by co-precipitation method. The morphology of the La3+/Co3O4NFs were characterized using scanning electron microscopy (SEM), and were further used to modify the graphite screen printed electrode (GSPE). The electrochemical behavior of acetaminophen at La3+/Co3O4NFs/GSPE has been studied in aqueous solutions. Experimental results showed that the La3+/Co3O4NFs modified […]
The use of less hazardous chemicals or natural material in place of toxic chemical for the formation of metal nanoparticle is known as green synthesis. The present paper deals with greener approach for the synthesis of silver (Ag) nanoparticles. The Saraca asoca plant leaves extract solution was used for the silver nanoparticles. Confirmation of Ag […]
In recent years, nanocomposite scaffolds made of bioactive polymers have found multiple applications in bone tissue engineering. In this study composite nanofibrous structure of gelatin (Gel)/chitosan (Cs)-polycaprolactone (PCL) containing hydroxyapatite (HA) were fabricated using co-electrospinning process. To assay the biocompatibility and bioactivity of electrospun nanocomposite scaffolds, the behavior of human osteosarcoma cells (MG63) on fabricated […]
In this paper, a novel ternary nanocomposite namely reduced graphene oxide/hydroxyapatite/silver (rGO/HAP/Ag) was prepared by a simple hydrothermal method using graphene oxide nanosheets, Ca(NO3)2, (NH4)2HPO4, and AgNO3 as starting materials. The as-prepared nanocomposite was characterized by using various photophysical techniques including Fourier transform infrared spectroscopy (FT-IR), Raman spectroscopy, X-ray diffraction (XRD), ultraviolet-visible (UV-Vis) spectroscopy, transmission […]
In this study, the use of TiO2/SiO2 nanocomposites investigated to remove nitrate and total ironfrom wastewater. The nanoparticles and nanocomposites were characterized by the Brunauer, Emmett, and Teller (BET), Field Emission Scanning electron microscopy (FESEM), Fourier transform infrared (FTIR), X-ray diffraction (XRD) and X-ray fluorescence (XRF). According to the BET results, the nanocomposite with 80%TiO2 […]
Polyethylene (PE) nanocomposites containing Cellulose Nano Crystal (CNC) were prepared via melt blending in a twin screw extruder. The evaluation of PE/CNC nanocomposites was studied for food packaging applications. The nanocomposites were investigated by thermal, mechanical analyses. Addition of CNC particle while having no effect on melting and crystallization temperature had intensive effect on the […]
The purpose of this study was to expand a trouble free biological method for the synthesis of silver nanoparticles (AgNPs) using the leaves extract of Rosa ChinensisL. to act as reducing and stabilizing agent. Water soluble phytochemicals played a vital role for the reduction silver ions into silver nanoparticles. The leaves extract was exposed to […]
Selenium has many roles on the functioning of humans and animals. Chicks as animal model can play an important role to distinguish the role/function of selenium. The objective of the present study was to test the effect of variable doses of nano-selenium supplement on the chicken gastrointestinal tract. A total of 180 male Ross chicks […]
