Aim We report synthesis of capped gold nanoparticles (C-AuNPs) of ≈20-30 nm by reducing HAuCl4 with flower and leaf extracts of Ocimum tenuiflorum, leaves of Azadirachta indica and Mentha spicata and peel of Citrus sinensis plants. Methods Atomic force microscopy (AFM) and transmission electron microscopy (TEM) determined their size, shape and topographical structures. The C-AuNPs with UV-Vis...

We generalize some identities and q-identities previously known for the symmetric group to Coxeter groups of type B and D. The extended results include theorems of Foata and Schützenberger, Gessel, and Roselle on various distributions of inversion number, major index, and descent number. In order to show our results we provide caracterizations of the systems of minimal coset representatives of ...

This work aimed to evaluate the potential of chitosan/cellulose nanocrystals (CNC) films be used as active pads for meat packages prolong its shelf-life and preserve properties over time. Several CNC concentrations (5, 10, 25, 50 wt%) were tested produced by solvent casting. The developed samples characterized ATR-FTIR, TGA, FESEM, XRD. transparency, antimicrobial, barrier mechanical also asses...

A novel Twitter context aided content caching (TAC) framework is proposed for enhancing the efficiency by taking advantage of legibility and massive volume data. For purpose promoting efficiency, three machine learning models are to predict latent events popularity, utilizing collected data with geo-tags geographic information adjacent base stations (BSs). Firstly, we propose a Dirichlet alloca...

Green synthesis of silver nanoparticles (AgNPs) has attracted substantial interest and achievement due to their environmental friendliness, ease manipulation, potential for large-scale production. By using aqueous Camellia sinensis leaf extract, suspensions AgNPs, which possess photocatalytic biological activity, were successfully synthesized in this study. The reduction ions AgNPs was visually...

Abstract Polyploidy induction could increase shallot bulb-size to raise consumer preference and local productivity. The research aimed obtain an effective method of polyploidy on callus onion ( Allium cepa ) var. Bima Brebes. experiment was consisted two experimental steps, which were polyploid the callus. A 1×1 cm treated by drops oryzalin with concentrations 0, 25, 50, 75, 100, 120 ?M. ploidy...

Abstract Zinc nanoparticles (ZnNPs) are showing promising medical applications. However, their cytotoxicity is relatively high. This study aims to use a green synthesis technique based on the natural propolis (honeybees glue) and produce three counterparts of (ZnO-NPs, AuNPs@ZnO AgNPs@ZnO). Then, would be analyzed for potential antibacterial activity cytotoxicity. The compares ZnO-NPs alone its...
