We describe a facile approach to controllable assembly of monodisperse Fe3O4 nanoparticles (NPs) on chemically reduced graphene oxide (rGO). First, reduction and functionalization GO by polyetheylenimine (PEI) were achieved simultaneously simply heating the PEI mixture at 60 °C for 12 h. The process is environmentally friendly convenient compared with previously reported methods. Meso-2,3-dimercaptosuccinnic acid (DMSA)-modified NPs then conjugated moiety which located periphery sheets via...

In this paper, the main concepts of interval type-2 (IT2), generalized (GT2), and type-3 (IT3) fuzzy logic systems (FLSs) are mathematically graphically studied. representation approaches sets (FSs), differences between IT2, GT2, IT3 were investigated. For first time, simple Matlab Simulink M-files by illustrative examples symmetrical FSs presented for practical use IT3-FLSs. The computations simplified By various examples, such as online identification, offline time series modeling, a...

We demonstrate a robust approach to functionalize the upconverted luminescent NaYF4:Yb/Er nanocrystals with folic acid (FA)–chitosan conjugates for specific targeting and imaging of lung cancer cells. In this approach, amine groups FA–chitosan covalently reacted carboxyl located on surface dimercaptosuccinic (DMSA)-modified NaYF4 : Yb/Er nanoparticles. The produced FA–chitosan-coated nanoparticles were characterized by means transmission electron microscopy (TEM) Fourier transform infrared...

The linear parameter-varying (LPV) models have broad applications in advanced mathematics and modern control systems. This paper introduces a new method for controlling the LPV includes gain-scheduled state-feedback technique fuzzy system to calculate gain. main goal of is stabilize bring its states equilibrium points. Linear matrix inequalities feedback gains system. On other hand, also produces combined signal with primary controller speed up this operation. Lyapunov’s theory used...

The fluorescent carbon dots (CDs) have found their extensive applications in sensing, bioimaging, and photoelectronic devices. In general terms, the synthesis of CDs is straight-forward, though subsequent purification can be laborious. Therefore, there a need for easier ways to generate solid with high conversion yield. Herein, we used collagen waste as source producing through calcination procedure without additional chemical decomposition treatment raw material. Considering mass acid has...

A key research topic in the field of robotics is formation control a group robots trajectory tracking problems. Using organized has many advantages over using them individually, such as efficient use resources, increased reliability due to cooperation, and better resistance against defects. To achieve this, controller proposed that steers leader robot subsequent follower asymptotically reference trajectory. The basic feedback linearization. ensure stability perturbations, compensator based...
