A Ru-Based Complex for Sustainable One-Pot Tandem Aerobic Oxidation-Knoevenagel Condensation Reactions.

Our novel binuclear complex-anchored Ru(III) catalyst, designed and assembled by sonicating 2,2'-(4,6-dihydroxy-1,3-phenylene)bis(1-benzo[]imidazole-4-carboxylic acid), Ru(DMSO)Cl and 4-methylpyridine, demonstrates remarkable efficiency and selectivity. It promotes one-pot reactions, including active methylenes and benzyl alcohols in water, via a tandem aerobic oxidation/Knoevenagel condensation process, yielding benzylidene malononitrile in excellent yields. The catalyst's ability to oxidize benzyl alcohols to aldehydes, which then undergo Knoevenagel condensation with active methylenes, makes it a multifunctional catalyst.

Alginate-modified graphene oxide anchored with lactoperoxidase as a novel bioactive nanocombination for colorectal cancer therapy.

It is imperative to explore new biocompatible drugs with low toxicity for use in medicinal fields such as fighting tumors. Bovine lactoperoxidase (BLPO) stems from the most important enzymes in the bovine whey that provide a proper pattern for nano-formulation with nanomaterials. LPO is a suitable protein to be coated or adsorbed to alginate modified graphene oxide (GO-SA), which forms the modified GO-SA-LPO hybrid structure.

Novel sulfonic groups grafted sugarcane bagasse biosorbent for efficient removal of cationic dyes from wastewater.

In this research, we reported the synthesis of effective sulphonated sugarcane bagasse (SCB@SA) biosorbent based on agriculture waste materials via a simple diazotization strategy for the removal of methylene blue (MB) and Bismarck Brown R(BB) dyes from waste water samples. First, the sugarcane bagasse (SCB) waste was collected, grinded, and sieved to obtain the desired size. Secondly, the SCB powder is modified with sulfanilinic acid (SA) via the formation of its diazonium salt to introduce sulfonic groups on the SCB surface.

Adsorption Study of Neodymium from the Aqueous Phase Using Fabricated Magnetic Chitosan-Functionalized Graphene Oxide Composites.

This work reports the performances of the magnetic chitosan@graphene oxide composite (MCh@GO) for the sorption of Nd(III) from aqueous medium. The prepared composite was synthesized by a coprecipitation method and then examined by FT-IR, XRD, SEM, and TGA. XRD analysis proved physical interactions between magnetic chitosan and graphene oxide through (inter- and intramolecular H-bonding and peptide bonding).
