This study presents the functionalization of liquid natural rubber (LNR) by iron-mediated radical chloro-nitration over the LNR backbone, resulting in a chloro-nitro compound of liquid natural rubber (Cl-N-LNR). The chloro-nitration was prepared by a reaction of LNR with iron(III) nitrate nonahydrate and iron(III) chloride in an organic solvent. T

This paper aims to provide information about the fractions of cadmium (Cd) and its distribution in surface sediment collected from bivalves harvesting areas in Binh Thuan province (Tuy Phong, Phan Thiet, Lagi). For this purpose, the sediment samples were collected monthly along with these areas in 2015–2016. To analyze the fractions of Cd, a five-step Tessier (1979) sequential extraction process was used, including Fraction 1 (Exchangeable), Fraction 2 (Bound to carbonate), Fraction 3 (Bound to iron-manganese oxide), Fraction 4 (Bound to organic compounds), and Fraction 5 (Residual).

Corrosion inhibitors are one of the practical and cost-effective way of preventing and inhibiting corrosion. An inhibitor's primary function includes creating a barrier by forming one or more molecular layers to protect against corrosive attacks. Organic molecules are one of the most popular, efficient, and practical corrosion inhibitors, and all studies demonstrate that organic compounds, preferentially those containing nitrogen (N), sulphur (S), and oxygen (O), have high inhibitory efficiency

This compound converted to Mannich base which interne illustrated as tridentate ligand of NO2-type. Meanwhile, the organic synthesis of the compounds is not an easy task, especially lactonization; hint naphthafuran-2-one has never been prepared from amino nitrile previously. Selected metal ions of known anticancer activity interacted with the ligand to present novel complexes to figure out the cytotoxicity effect of both organic and inorganic parts against cancer cell line.

Flame retardants (FRs) play an important role as additives which is applied in a wide range of products because they can inhibit ignition to delay the spread of fire. By adding fly ash (a waste of thermal power plants), we have developed an epoxy resin material with good flame retardant properties. Besides, using the fly ash can reduce the consumption of current flame retardants (organic halogen compounds) and thus meet the environmental safety of flame retardant epoxy resin.

Terpenoid indole alkaloids (TIAs) vincristine and vinblastine are two essential anticancer drugs used in cancer treatments. These compounds are naturally available only in Catharanthus roseus in low accumulation, leading to efforts to upregulate TIAs substances through other expression organisms. The combination of vindoline and catharanthine into α-3∼,4∼- anhydrovinblastine (AVLB) is an important step for the biosynthesis of vinca alkaloids, which serves as a precursor to vinblastine and vincristine.
