The development of green nanotechnologies has garnered significant attention from researchers, particularly in the ecological synthesis of nanoparticles. This study presents the biogenic synthesis of stable zinc oxide nanoparticles (ZnO NPs) using extracts from the leaves of Camellia sinensis. The synthesized nanoparticles were characterized using ultraviolet-visible spectroscopy (UV-Vis), infrared spectroscopy (IR), and Xray diffraction (XRD) analysis. The results demonstrated that the Camellia sinensis leaf extract effectively reduced zinc ions to form zinc oxide nanoparticles. XRD analysis confirmed the crystalline structure of ZnO, with the nanoparticles exhibiting a size range of 26-38 nm. This biosynthesis method provides a rapid, sustainable, and environmentally friendly approach to produce stable zinc oxide nanoparticles, offering potential applications in various fields.

There are approximately 317 species in the genus Eryngium (Sea Holly), which belongs to the Apiaceae (Umbelliferae) family [1-2]. Some of these species have long been utilized as antinociceptive agents and treatments for various inflammatory conditions [1]. Secondary metabolites isolated from plants in this genus have demonstrated significant biological activities, including anticancer, antibacterial, molluscicide, parasiticide, antimicrobial, antifungal, cytotoxic, and phototoxic properties [1–3]. Among other Eryngium species, Eryngium triquetrum Vahl, commonly known as choukzerk, is widely distributed throughout Algeria and is native to North Africa [1].Algeria is home to 3,139 plant species and features some of the most unique and diverse vegetation in the Mediterranean basin . We observed the presence of this species in the semi-arid region of Maadid in M’sila. In this study, we investigate the polyphenol content and antioxidant activity of Eryngium triquetrum Vahl extract, which was produced using maceration with a methanol/water mixture (70/30). The role of free radicals in biological processes is increasingly recognized, as they are believed to play a significant role in the development of tissue damage and pathology in living organisms [4]. Our findings indicate a high total phenolic content in the extract of Eryngium triquetrum Vahl. The antioxidant activities, measured by the DPPH method[5], were notably significant for the Eryngium triquetrum Vahl extract, which demonstrated a favorable IC50 value; however, this extract was found to be less active compared to BHA.

These advancements have significant implications for various industries, including automotive, aerospace, packaging, and electronics, where the nanocomposites can be utilized for lightweight structural components, flame-resistant coatings, and high-performance packaging materials. Increasing the interlayer distance (d-spacing) of fractioned sodium montmorillonite (FMMT-Na) using N,N,N-trimethyl-1-hexadecyl ammonium chloride (THDACl) is done to improve the compatibility and dispersion of the clay in polymer matrices. This modification is relevant and beneficial as it enhances the mechanical properties, barrier performance, and thermal stability of the resulting nanocomposites, opening up opportunities for various applications in industries such as packaging, automotive, construction, and electronics. PS nanocomposites were prepared by incorporating MMT clay using THDACl as a surfactant. The composition ratios included 1-10% weight percentage of MMT with a 1:1 weight ratio of THDACl to MMT. The melt compounding process involved treating MMT with THDACl, dispersing it in a solvent, and adding it to melted PS pellets. Characterization techniques, such as XRD, TEM, SEM, TGA, and mechanical testing, were used to evaluate the nanocomposites. The results demonstrated improved dispersion, enhanced mechanical properties, and increased thermal stability. These findings contribute to the optimization of the nanocomposites for specific applications.

The aim of this work is,in side to study the adsorbent effect and in the other side the evaluation of antimicrobial activity of the snail shells Hélix aspersa. Three different samples are prepared : the crude biomasse CE, the biomasse activated by nitric acid AN and the biomasse activated by CaCl2 :CC. The preparation yields ranging from 72% for the AN sample and 98.6% for CC. The pHPZC values for the different samples are very similar and have a number around 8 which signifies a basic medium. The thermogravimetric analyzes did not give much information because of the low temperature range (< 800°C) while the analysis by infrared spectroscopy shows similar functional groups of calcium carbonate. The values of the iodine index and the methylene blue index show the great porosity of these shells, in particular, the AN sample which reaches (985 ± 1) for the iodine index and (299, 5 ± 0.05) for the methylene blue index. Applying these results to a model dye like malachite green, we found good results especially for the AN sample. The evaluation of the antimicrobial activity shows a great inhibition against the strain of gram negative and gram positive, a bactericidal effect against Staphyloccocus aureus and almost bactericidal against Echerichia coli. The evaluation of antifungal activity against Fusarium clomorum and three fungal strains of the Aspergillus genus show that these shells have fungicidal activity against Fusarium clomorum and significant inhibition for Aspergillus strains.

Seseli L. is an important genus of the Apiaceae family, with a large number of aromatic species. It is used in traditional medicine extensively, but there is quite limited information on their phytochemicals and biological activities. Seseli praecox is a rare species growing in the north east of Algeria, and there are no phytochemical studies on this species. In the present study, we aimed to investigate the effect of the polyphenolic extract of this plant for its antioxidant activity using β-carotene bleaching assay. The oxidation of linoleic acid produces hydroperoxide derived free radicals which attack the chromophore of β-carotene resulting in bleaching of the reaction emulsion and the antioxidant activity was expressed as percent inhibition relative to the control. Results show that Seseli praecox have an inhibition percentage range from 72% to 43%. Consequently, this study demonstrated the antioxidant potential of the extract from S. praecox. Further studies are required to identify the mechanisms underlying these effect.

These deposits were obtained from watts bath. In the study, the cyclic voltammetry technique was employed to provide a better understanding of the cathodic behavior of nickel deposition. The effects of the potential scanning rate and the effect of cathodic limits on cyclic voltammograms deposition of Ni in Primitive Watts Bath (BWP) were determined. The composite coatings of nickel incorporating TiO2 nanoparticles were characterized using various electrochemical techniques such as open circuit potential (OCP) and potentiodynamic polarization measurements, and electrochemical impedance spectroscopic methods. The current density values for the Ni-TiO2 in the case of 5 g/L and 10 g/L of TiO2 determined from the polarization curves recorded in 3.5% NaCl indicate that the corrosion process on nickel incorporating the TiO2 nanoparticle composite surface is slower than on pure nickel. The TiO2 particles embedded in the electroplated nickel, increase the polarization resistance and decrease the corrosion rates as compared with electrodeposited pure nickel. Electrochemical impedance spectra obtained at the open-circuit potential (OCP) in 3.5% NaCl showed an increase of polarization resistance with time in all cases.
