Synthesis of calcium oxide nanoparticles (CaO NPs), its characterization and kinetic evaluation with phosphite ion and soil sample in acidic solution was evaluated. CaO NPs was synthesized by thermal decomposition method at 850 0C for 6 hours using calcium carbonate (CaCO3) as the raw material. The CaO nanoparticle was characterized by the use of X-ray Diffraction (XRD) and Scanning Electron Microscope (SEM). The sharp peak of CaO NPs was found to be between 17.98o and 71.7o with average crystallized particle sizes of 27.43 ± 0.1. The morphology was found to be a flower shape with agglomeratio..read more

The innovation of this study consists of using superheat water to extract phenols from Wild hemp stem leaves. First, the effects of three factors were explored on the yield of phenols, and the results showed that these three factors had a dual impact. Then, based on single-factor experiment results, the most significant yield was achieved by the implementation of the three-factor and three-level Box-Behnken design, and it was 84.78±1.24 mg of gallic acid equivalents under optimal conditions (197 ℃, 43 min, 21 mL/g). In addition, quinic and rosmarinic acids were the main components of phenols b..read more

Flavokawain B (FKB) is a naturally occurring chalcone that exhibits potential anti-cancer properties. Density functional theory (DFT) is a computational simulation approach used to investigate the electronic properties of molecules. Here, we investigated the structural-activity relationship and optoelectronic properties of naturally occurring chalcones; FKB and their derivatives named (E)-3’-(2’-fluorophenyl)-1’-(2’-hydroxy-4',6'-dimethoxyphenyl)prop-2-en-1-one (KG1), (E)-3'-(2'-chlorophenyl)-1'-(2-hydroxy-4',6'-dimethoxyphenyl)prop-2-en-1-one (KG2), (E)-3'-(4'-bromophenyl)-1'-(2'-hydroxy-4',6..read more

Nowadays, biocompatible, and cost-effective material design is one of interesting fields in biological process. In this regard, Magnesium/Aluminum Layered Double Hydroxides (Mg/Al LDHs) synthesized and fabricated with environmental benign anions was investigated like Citrate and Gallate. Furthermore, these modified Mg/Al LDHs were treated with chitosan in order to increase the biocompatibility of the compounds. The Fourier-Transform Infrared (FTIR), Scanning Electron Microscopy (SEM), Energy dispersive X-ray (EDX) and X-ray Diffraction (XRD) analysis confirmed that modification has done succes..read more

This study presents the synthesis, structural characterization, and application potential of strontium-dextrin metal-organic frameworks (Sr-MOFs) using a single-step crystallization mechanism. In the synthesis process, the Sr atom functions as a pivotal connecting node, directly bonding with both carbon atoms and the organic linker to form the framework. The reaction between the organic linker and the corresponding strontium bromide precursor yields brown crystalline Sr-MOFs. Following synthesis, the crystals were collected, characterized, and evaluated for their thermal stability, solubility,..read more

Two new 8-hydroxyquinoline (8-HQ) derivatives, namely 5-((4-chlorobenzene) diazene) -8-hydroxyquinoline (N-HQ) and 5-((4-chlorobenzene) methylene amino) -8-hydroxyquinoline (C-HQ), were designed and synthesized. Their structures were characterized by 1H NMR, 13C NMR, FT-IR and HR-MS. Their physical and photoelectrochemical properties were studied by absorption, emission, electrochemistry and thermog ravimetry. In addition, the gaussian program was used to calculate the geometric configurations of the two derivatives. Since N-HQ has an approximate planar configuration, it is packed in a highly ..read more

This review paper examines the efficiency of hydro-desulfurization catalysts in removing sulfur compounds from fuels. Specifically, the focus is on bi- and tri-metallic catalysts based on transition metal sulfides (TMS), such as Ni/Co-promoted Mo and W, which effectively eliminate sulfur from challenging compounds present in fuels. The paper is divided into three main sections, each addressing the production of diesel fuel with extremely low sulfur levels using these catalysts. The first section discusses supported catalysts, followed by self-supported or unsupported catalysts, and concludes w..read more

This article is a review of minerals that are used to modify the physical and mechanical properties of polymers and obtain composites with improved performance characteristics. A general classification of fillers is presented, taking into account their division into dispersed and reinforcing ones. General characteristics of fillers are given and their division into groups is considered: mineral, organic, and other subgroups depending on the type of polymer matrix used. To obtain polymer nanocomposite materials with an improved set of properties, information is provided on the features of selec..read more
