Metallic nanoparticles (NPs) manufactured by ecofriendly strategies have also received much interest because of their elastic scattering properties and performance in nanomaterials. Aluminium oxide nanomaterials stand out among nanomaterials due to their tremendous uses in ceramic products, fabrics, therapeutic agents, catalyst supports, sewage sludge, and biosensors. The current paper investigates the effect of the nanoparticle composition and layer sequential on the mechanical characteristics of jute (J)-hemp (H) incorporated with an aluminium oxide polymer composite. NaOH is used to change the physical aspects of both plant fibres. A total of 20 specimens were tested with varying stacking sequences and padding weight ratios. Mechanical properties like a nanocomposite’s tension, bending, and ILSS was measured. Stacked series and flowability substantially impact the nanocomposite. The Group 3 nanocomposite with 2% Al2O3 has the highest tensile strength, 54.28% of the Group 1 and 2 combinations. The stack series significantly influences the material properties of nanomaterials. Because of the alternating layers of natural fabrics, Group 4 specimens have the maximum flexural strength. Group 3 composite materials have the highest ILSS because they have hemp on the outermost surface. It has been discovered that Group 4 material with a 2% Al2O3 concentration is possibly the most substantial material. The existence of Al2O3 nanoparticles in the green synthesis was confirmed by XRD analysis.

AMG Transcend Association
Biosynthesised α-Fe2O3-CdO electrochemical nanosensor attained from Coriandrum sativum leaves extract and fabricated on the screen-printed electrode to detect chloridazon (CLZ) herbicide in agricultural food samples. Scanning electron microscopy, energy dispersive x-ray analysis, X-ray diffraction spectroscopy, cyclic voltammetry, and differential pulse voltammetry were used to investigate the α-Fe2O3-CdO electrochemical nanosensor. The optimization factors of the effect of pH, accumulation time, accumulation potential, and foreign substances were elevated. The α-Fe2O3-CdO/SPE electrochemical nanosensor shows the significant voltammetric response for the CLZ detection. Foreign substances did not considerably influence pesticide detection. Dynamic linear CLZ plot for a standard solution of CLZ was obtained in the concentration range of 0.1 to 36.00 µg⸳mL-1 (R=0.995) with a limit of detection 0.059 µg⸳mL-1 and a quantification limit of 0.179 µg⸳mL-1. The proposed electrochemical nanosensor was used to detect CLZ in agricultural food samples and agreeable recovery results.

The goal of this research is to increase the performance of AA 7150 reinforced with TiO2 microparticles by optimizing the stir casting parameters. The response surface method's central composite design technique was used to optimize the three stir casting factors of stirring temperature (A), stirring speed (B), and stirring time (C). The ultimate tensile strength, hardness, impact strength, elastic modulus, and compressive strength were all tested. With the aid of analysis of variance, it was discovered that it had a substantial influence on the test samples' characteristics responses. 5 quadratic experiments were linked using factors' characteristics. At a level of 95% confidence, the models were found to be statistically important, and the variations were found to be less than 5%. The response surface was used to assess the parameter interaction profile. Each interaction's contour plots provided a range of stirring settings within which each property may be maximized.

ANSF Publications
Glassy carbon electrode modified sensitive Pd-CuO/MWCNTs electrochemical nanosensor was used for detection of ametridione pesticide in water samples. The morphology characteristics of Pd-CuO/MWCNTs are examined by scanning electron microscopy and EDX. The ametridione pesticide under voltammetric investigation involves irreversible, 4e? electron reduction based on the protonation of the two carbonyl groups (>C=O). The voltammetric method was applied for the detection of ametridione in BR buffer solution at pH 5.0 as a supporting electrolyte. The detection limit, limit of quantification and concentration ranges of the proposed method were 0.0796 ?g?mL?1 (signal/noise=3), 0.5560 ?g?mL?1 and 0.1 to 10.0 ?g?mL?1, respectively. The electrochemical sensor was successfully applied for the detection of ametridione in tap, agricultural run-off and river water samples showing >98% mean recoveries. 

Influence of annealing on structural and morphological of spray pyrolysis deposited CoFe<inf>2</inf>O<inf>4</inf> thin films

ABSTRACT The CoFe2O4 (CFO) thin films were deposited on a glass substrate by spray pyrolysis cobalt ferrite aqueous solutions. These are characterized by XRD, Raman, FTIR, FE-SEM with EDAX, AFM, I–V and UV–vis spectroscopy analysis. Thin films are annealed at different temperatures (300, 350, 400, 450 and 500 °C) to enhance the crystallinity of films. The effect of annealing temperature on structural, morphological, elemental and optical properties of the films has been investigated. As the annealing temperature increases, the thin films become more crystalline. The annealed samples show the symmetrical and anti-symmetrical stretching vibrations in Co species. The authors observed the slight shift in Raman modes, good surface morphology, crystallite size of the sample which increases gradually with respect to temperature, good elemental composition and the band gap energy which decreased due to increase in grain size of the CFO thin film.

Abstract A selective, sensitive novel electrochemical sensor for detection of methyl parathion on the preparation of a carbon dots (C-dots)/ZrO 2 nanocomposite was developed. The C-dots/ZrO 2 nanocomposite was fabricated using electrochemical deposition onto a glassy carbon electrode and characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy and cyclic voltammetry. The optimum parameters such as effect of pH, accumulation time, accumulation potential, scan rate, effect of amount of C-dots and effect of amount of ZrO 2 were investigated. The C-dots/ZrO 2 modified glassy carbon electrode allowed rapid, selective determination of methyl parathion in rice samples by adsorptive stripping voltammetry. The stripping response was highly linear over the methyl parathion concentrations ranging from 0.2 ng mL − 1 to 48 ng mL − 1 , with a detection limit of 0.056 ng mL − 1 . This novel electrochemical nanocomposite-based electrochemical sensor was successfully applied for the detection of methyl parathion in rice samples.

Selective detection of copper ion in water by tetradentate ligand sensor

Elsevier BV
Abstract Tetradentate ligand, 3,5-bis(((2-hydroxynaphthalen-1-yl)methylene)amino)benzoic acid (3,5-BHNMABA), was synthesized for the selective detection of copper ion. The fluorescence of the ligand in solution was quenched about 72% by Cu(II) and about 18% by Fe(II), but it was scarcely influenced by the existence of other metal ions. The ligand was chemically bound on self-assembled monolayer on indium tin oxide electrode. The as-prepared electrode exhibited the electrochemical recognition ability for metal ions: Cu(II) could be selectively caught to 3,5-BHNMABA ligand on the electrode, but Fe(II) and other metal ions did not display electrochemical response. Results indicate the selective coordination linkage of Cu(II) with the ligand both in solution and on electrode, being different from other ions. It can be concluded that the 3,5-BHNMABA-functionalized electrode is a favorable sensor for the selective detection of Cu(II) in water.

International Association of Physical Chemists (IAPC)
Graphene oxide (GO) modified NiO electrochemical nanosensor was developed for the determination of the dinoterbon in food samples using adsorptive stripping voltammetry. The modified nanosensor characterized by TEM, XRD, cyclic and adsorptive stripping voltammetry. Dinoterbon pesticide exhibited a single well-deﬁned cathodic peak at pH 4.0 at Britton–Robinson buffer (-810.0 mV). The voltammetric characterization of the pesticide residues is evaluated and the parameter such as the effect of pH, scan rate, pulse amplitude, deposition potential and deposition time were optimized. The current–concentration plot obtained using this peak was straight-lined over the range from 0.05 to 50.00 µg mL-1 with limit of detection (LOD) 0.028 µg mL-1. The proposed method was efficiently applied to the determination of dinoterbon in food samples. The mean recoveries of the pesticide 97.40 to 99.88 % with a relative standard deviation of 0.114 % in food samples respectively.
