Herein, Fe-doped C3N4 high-performance photocatalysts, synthesized by a facile and cost effective heat stirring method, were investigated systematically using powder X-ray diffraction (XRD), Fourier transform infrared (FTIR), scanning electron microscopy (SEM) Brunauer–Emmett–Teller (BET) surface area measurement, photoelectron (XPS), UV–Vis diffusion reflectance (DRS) photoluminescence (PL) spectroscopy. The results showed that Fe ions incorporated into g-C3N4 nanosheet in both +3 +2...

Magnetically separable core/shell Fe3O4/ZnO heteronanostructures (MSCSFZ) were synthesized by a facile approach, and their application for enhanced solar photodegradation of RhB was studied. The formation mechanism MSCSFZ proposed, in which Fe3O4 nanoparticles served as template supporting anchoring the ZnO crystal layer shells. morphology can be varied from spherical to rice seed-like structures, bandgap able narrowed down 2.78 eV controlling core-shell ratios. As result, exhibited...

The main object of this paper is to further extend the MITC4 element analyse free vibration FG sandwich spherical shells with a honeycomb core (so-called h-FGSS shells) resting on Kerr foundation (KF). originates from three-dimensional continuum description degenerated shell behaviour which can be applied both thick and thin shells. consists an inner two different skin layers. FSDT used due its simplicity efficiency. KF includes three parameters as upper springer stiffness (kU), (kL), shear...

The methanol oxidation reaction (MOR) has recently gained a lot of attention due to its application in fuel cells and electrochemical sensors. To enhance the MOR, noble metal nanoparticles should be homogeneously dispersed on electrode surface with aid one suitable support. In this work, 4-aminothiophenol (4-ATP) molecules which contain simultaneously amine thiol groups were electro-grafted onto provide anchoring sites, limit aggregation ensure good dispersion nanoparticles. results showed...

In this paper, we report experimental evidence of anomalous and planar Righi-Leduc effects on $\mathrm{NiFe}$. The effect is the thermal analog Hall effect, in which electric current replaced by heat field temperature gradient. When material ferromagnetic, it well known that there are two other contributions to voltage depend orientation magnetization. These extra called when magnetization out plane sample sample. same way, an a shown appear transverse gradient generated current.

In this work, a bifunctional nanocomposite based on silver and iron oxide nanoparticles (AgNPs/Fe3O4) was prepared then used as SERS substrate (surface-enhanced Raman spectroscopy) for sensing diclofenac which is one of the most widely non-steroid anti-inflammation drugs. AgNPs/Fe3O4 synthesized by combining co-precipitation in-situ reduction nanoparticles. Morphology structural studies revealed conjugated structure in (80 nm diameter) were surrounded (18 diameter). There slight blue-shift...

Effect of heating time on the structural, morphology, optical, and photocatalytic properties graphitic carbon nitride (g-C 3 N 4 ) nanosheets prepared at 550 °C in Ar atmosphere is studied. The investigations are carried out by using x-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), UV–vis absorption, photoluminescence (PL). At a temperature °C, g-C nanocrystals formed after 0.5 h become more orderly as increases. surface area...

The resistance of a ferromagnetic cylindrical Ni nano-constriction has been measured as function the external magnetic field. Typical profiles versus field are observed with irreversible jumps separated by stable plateaus, showing systematic slow relaxation effects. An interpretation in terms magnetomechanical strain at level constriction is proposed. This scenario allows behaviour to be understood displacement dislocations or similar metastable structural defects.

Abstract In this work, the polyaniline/reduced graphene oxide (PANi/rGO) bilayer was directly electrodeposited on carbon screen‐printed electrodes (SPE). Some details in growth of PANi/rGO were revealed from cyclic voltammograms and X‐ray photoelectron spectra. The stacked rGO film at high compactness electrode surface is mainly accompanied with reduction epoxy functional groups basal planes graphitic flakes. as‐grown layer abundent hydroxyl preferable to attract intrinsic fibrillar‐like...

Abstract In this study, we developed a green and easy to scale up approach for producing Au/g-C 3 N 4 (Au/GCN) hybrid plasmonic photocatalyst without using the chemical reducing agents via growing of Au nanoparticles (Au NPs) on surface GCN nanosheets under photo-reduction ultraviolet (UV)-radiation. Different characterization techniques were conducted investigating structure, morphology, chemistry optical properties as-prepared catalysts. The scanning electron microscope image shows that...

The issue of Vietnamese nationals consistently having some the highest numbers referrals into UK’s National Referral Mechanism (NRM) is increasingly apparent. However, this did not gather nationwide attention until Essex tragedy October 2019 which saw 39 found lifeless in a lorry after they were brought country by criminal network human traffickers and smugglers. This paper seeks to understand circumstances these victims trafficking Britain reviewing situation both countries—Vietnam UK....

The Righi-Leduc effect refers to the thermal analogue of Hall effect, for which electric current is replaced by heat and field temperature gradient. In both cases, magnetic generates a transverse force that deviates carriers (electron, phonon, magnon) in direction perpendicular current. ferromagnet, magnetization plays role field, corresponding called anomalous effect. Furthermore, second contribution due anisotropy, planar superimposed We report experimental evidence counterpart effects...
