In this work, a facile approach was successfully developed for in situ catalyzing Au nanoparticles loaded on Fe3O4@SiO2 magnetic nanospheres via Sn2+ linkage and reduction. After the MNPs were first prepared sol–gel process, only one step needed to synthesize Fe3O4@SiO2–Au nanocomposites (Fe3O4@SiO2–Au MNCs), so that both synthesis reaction cost remarkably decreased. Significantly, as-synthesized MNCs showed high performance catalytic reduction of 4-nitrophenol 4-aminophenol could be reused...

In this paper, we first discovered that Co3O4 nanoparticles (NPs) possess intrinsic oxidase-like activity and can catalytically oxidize peroxidase substrates, such as 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) 3,3',5,5'-tetramethylbenzidine (TMB), to form colored products, in the absence of exogenously added H2O2. The presence sulfite inhibited TMB-O2-Co3O4 NPs reaction system caused a change color system. On basis phenomenon, colormetric approach detect...

In this paper, a novel and simple colorimetric method for the determination of reduced glutathione (GSH) based on Fe3O4 magnetic nanoparticles (MNPs) as peroxidase mimetics was developed. The MNPs prepared via coprecipitation method, which possess intrinsic peroxidase-like activity, were used catalyst in color development reaction substrate 2,2′-azino-bis(3-thylbenzo-thiazoline-6-sulfonic acid) diammonium salt (ABTS) H2O2. existence GSH can consume H2O2 cause change system be detected by...

A novel Lewis base-catalyzed [4 + 3] annulation process for the construction of benzo[b]oxepine scaffolds has been developed. 1,4-Diazabicyclo[2.2.2]octane (DABCO) promotes union o-QMs and Morita–Baylis–Hillman carbonates in reasonable to excellent yields good stereoselectivities (dr > 20:1). This straightforward, catalytic approach offers access a variety synthetically useful derivatives bearing oxindole containing all-carbon spiro-quaternary stereocenters.

A novel metal-free one-pot protocol for the effective and efficient synthesis of 3-phosphinoylbenzofurans via a phospha-Michael addition/cyclization H-phosphine oxides in situ generated ortho-quinone methides is described. Based on expeditious construction C(sp2)–P bonds, asymmetric optically pure containing chiral P-stereogenic center has also been probed by using RP-(−)-menthyl phenylphosphine oxide.

This paper deals with the problem of a quadrotor experiencing total failure one actuator. First, nonlinear mathematical model for faulty is derived three control inputs and six outputs, which includes translational rotational dynamics. Because limited inputs, controllability yaw state sacrificed, are reallocated to other healthy rotors. Second, controller designed based on proposed model. presented two subcontrollers: 1) roll angle, pitch altitude subcontroller 2) horizontal position...

An accurate and reliable turbofan engine model which can describe its dynamic behavior within the full flight envelop lifecycle plays a critical role in performance optimization, controller design fault diagnosis. However, due to differences caused by tolerance of manufacturing assembly, degradation during continuously stringent environmental regulations, accuracy is severely reduced. In this paper, an adaptive modification method nonlinear Component-Llevel Model (CLM) based on Long...

This study addresses the inefficiency, high crop damage, and poor adaptability of traditional cornfield weeding machinery. A High-Clearance Inter-Row Weeding Robot Chassis was developed tested through simulations experiments. With a refined suspension floating wheels, it achieves 800 mm ground clearance for dual-row weeding. Simulations show maximum chassis stresses 124.7 MPa 134.88 under sharp turns braking. Stability assessments indicate theoretical climb angles 26.5° longitudinally 35°...
