Herein, we report an artificial nanoenzyme: CoSe2 with unique flake like morphology, exhibiting an excellent intrinsic peroxidase like activity. In comparison with naturally found Horseradish peroxidase (HRP), silver and gold based biomimetics, these nanoflakes mimics enhanced peroxidase like activity with higher Kcat and Vmax values for oxidation of both 3,3,5,5-tetramethylbenzidine (Kcat = 42.8 s-1

A fluorescent Au nanocluster LRL−AuNCs modified with RGDK-containing peptide was synthesized with a simple one-pot method. Based on the “turn-off” model, LRL−AuNCs displayed high sensitivity and selectivity for sensing Cu2+. It showed a good linear calibration between the fluorescence intensity and Cu2+ concentration in the range of 5 ∼ 80 μM (R2=0.998), with the detection limit 3.9 μM. which is far

This work features synthesis, characterization and sensing activity of a novel 1D copper(II)-1,2-diamminocyclohexane (DACH) based coordination polymer with formulation [Cu2(DACH)2Cl3H2O]n (CP1). DFT and Hirshfeld surface analysis of CP1 have been carried out to study the electronic structure and intermolecular interactions of the crystal framework. Owing to remarkable stability and aqueous solubility

The catalytic effects of metal nanoparticles (MNPs) synthesized in sodium bis(2-ethylhexyl) sulfosuccinate (AOT) microemulsion system by using M(II) salts (M=Fe, Co, Ni) and NaBH4 reducing agent on methylene blue (MB) degradation reaction were investigated. It was determined that Co-MNPs gave the best catalytic activity among them. Influence of the reaction parameters e.g., reaction time, temperature

Nickel-based metal organic framework (Ni-MOF) and carbon nanotubes composite (Ni-MOF/CNTs) is constructed via in situ self-assembly of Ni-MOF in the presence of CNTs solution. The obtained electrode (Ni-MOF/CNTs) exhibits sensitive response toward the detection of taxifolin by significantly enhancing the redox peak currents and decreasing the peak-to-peak separation. Under the selected conditions,

Herein we report the structural, morphological, photoluminescence (PL) and thermoluminescence (TL) properties of Li co-doped CaSO4:Ce3+ nanophosphors prepared successfully via co-precipitation method. The PXRD pattern confirmed the single-phase hexagonal structure with space group P3121(152) with JCPDS Card no. 76-02312. The average crystallite size was estimated by Scherrer’s and W-H methods are found

In this work, we report the synthesis and electrochemical performance of CuO synthesized in aloe-vera gel medium coated LiNiPO4 in first time also, we compared the performance of CuO prepared in water medium coated LiNiPO4. The particle size of pure LiNiPO4 is 5.2 μm and the particle size of CuO prepared in water medium coated LiNiPO4 is 2.1μm. Also, the particle size of CuO prepared in aloe-vera gel

In this demonstration, conductive carbon (CC)/BiOBr composite photocatalysts were prepared by a one-pot solvothermal approach. The CC/BiOBr composites were studied by Brunauer-Emmett-Teller (BET), X-ray diffraction (XRD) and scanning electron microscope (SEM), high resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS), UV-Vis diffusion reflectance spectrometry

The Fe2O3@MgO, Fe2O3@Mn2O3, and Fe2O3@Co3O4 nanocomposites were developed using a two-pot wet chemical procedure. The structure and the phase were confirmed using the Powder X-Ray diffraction tool (PXRD). The optical properties of the prepared materials were analyzed using Photoluminescence (PL) and Diffuse Reflectance Spectroscopy (DRS) technique. Surface morphology and elemental composition of the
