In this work, chitosan/graphene nanocomposite granules with weight percentages of 0.5%, 1%, 2% and 5% were prepared using a solution method. At first, graphene was oxidized sulfuric nitric acid then triethylenetetramine grafted on surface. Functionalized characterized by Fourier-transform infrared spectroscopy (FT-IR), Therapeutic Goods Administration (TGA), X-ray energy diffraction (EDX) Scanning electron microscope (SEM). Results showed functionalization successfully accomplished. The...
Sol-gel chemistry is currently applied as one of the most widely used methods for synthesis nanoparticles. In this method hydrolysis and poly-condensation reactions occur when gel precursors are mixed with water catalyst. The further condensation sol particles into a three-dimensional network produces gel. There several parameters that effect on gelation time such molar ratio alkoxide to water, rate hydrolysis, type amount catalyst used, initial concentration temperature drying. Encapsulated...
Abstract A simple, rapid, and low‐cost method for preparation of Co 3 O 4 nanoparticles (Co ‐1 ‐2) using solid‐state calcination mixture Co(NO ) 2 ∙6H salicylic acid (1:1 weight ratio) at two different temperatures 500 600°C is reported. The morphologies structure the as‐prepared were characterized X‐ray diffraction (XRD) transmission electron microscope (TEM). In addition, we tested them as an anode material lithium‐ion batteries. cycling stability electrochemical performance excellent....
Detection of DNA molecules and possible chemotherapy-induced changes in its structure has been the goal researchers using rapid, sensitive inexpensive approaches. Therefore, aim this study was to fabricate a new electrochemical biosensor pencil graphite electrodes modified with polypyrrole/Ce doped hexagonal nickel oxide nanodisks or PP/Ce-doped H-NiO-ND composites for determination Abemaciclib (AMC) ds-DNA molecules. The prepared by immobilizing on surface H-NiO-ND/PGE. Differential pulse...
In this paper, we investigate the propagation of optical vortices carrying orbital angular momentum in a coherently prepared graphene quantum dot (GQD) system. Using Maxwell–Bloch equations and assuming weak light–matter interaction, examine two key scenarios. The first scenario involves transfer through nonlinear parametric process, starting with one vortex beam absent then generated during its interaction GQD We analyze how various system parameters affect conversion efficiency matching...
Abstract Polyethylene glycol (PEG) has been globally recognized as an environmentally‐friendly chemical solvent used in many disciplines for various purposes. In this work, intelligent models are constructed based upon least squares support vector machine (LSSVM) and adaptive neuro‐fuzzy inference system (ANFIS) methodologies optimized with either genetic algorithm (GA), coupled simulated annealing (CSA) or particle swarm optimization (PSO) to estimate PEG density terms of molecular weight,...
