The concentrations of trace metals in crude oil samples and core well rocks obtained from five oil fields: Halfaya, Noor, Amara, north, and south Buzurgan, were analyzed using an atomic absorption spectrophotometer. The ...

The aim of this study was to formulate brinzolamide microparticles using a synthesized novel, biodegradable, amphiphilic and tri-block poly-caprolactone- polyethylene glycol-poly-caprolactone (5000–1000-1000) co-polymer ...

Some amide derivatives of drugs containing a carboxyl group (Diclofenac¸ ketoprofen, oxaprozin, and naproxen) were prepared with one of the aniline derivatives. The effective method for preparing amides involves coupling ...

In this study, the synthesis and characterization of a ternary nanocomposite consisting of rGO, Fe3O4 and ZrO2 NPs are explored. The nanocomposite might be useful in removing Terasil black dye from aqueous solutions in ...

A comparative study of preparation of two biopolymer nanocomposites, by free radical graft copolymerization of sodium alginate (SA) was done with two monomers such as acrylic acid (AAc) and itaconic acid (ITA) like poly ...

Today's nanocomposites with strong photocatalytic degradation are used for removal of pollutants. A low-cost method for creating materials with zinc oxide nanostructures intended to be employed in the treatment of water ...

In this study, a soot–poly(o-toluidine) nanocomposite (St-POT) was synthesized via candle soot (St) nanoparticles were impregnated on poly-o-toluidine (POT) by in situ oxidative polymerization under ultrasonic field. The ...

A simple, rapid, and sensitive automated CFIA/MZ method was suggested for determination of p-amino benzoic acid (PABA) in pure material. This procedure was based on the diazotization of PABA via the reaction of sodium ...

New Schiff base ligand (SFB) was synthesis from folic acid, boric acid, and one of amino acids (4-nitrobenzaldehyde) in 1:1 mol ratio. The metal complexes synthesized by the reaction of (FeCl3·6H2O, CuCl2·2H2O, and AgNO3) ...

The production of the new azo compound via a diazotization reaction between 4-aminobenzoic acid and ethyl acetoacetate is the aspect of the investigation by more than one technique FT-IR, 1H-NMR and UV-Vis spectrophotometry. ...

The hybrid nano sized material ZnO-WO3 nanocomposite was synthesized utilizing as known hydrothermal method. The incorporation of WO3 NPs into the zinc oxide structure raised the porosity and surface area, besides a rise ...

This article includes designed and synthesized for bent-shaped liquid crystal molecules starting from 5,5-diethylpyrimidine-2,4,6(1H,3H,5H)-trione and two moles of chloroacetylchloride in N, N-dimethyl formamide (DMF) and ...

In this study, poly (acrylamide-co-cis-2-butene-1, 4-diol) was synthesized by polymerization of various molar ratios of acrylamide and cis-2-butene-1, 4-diol using ceric ammonium nitrate (CAN) as redox initiator. The ...

This study presents a rapid, sensitive, and straightforward approach to measure chlorpheniramine maleate (CPM) using turbidity CFIA. The method involves reacting of CPM with phosphomolybdic acid (PHMA) to produce a pale ...

Aducanumab, a monoclonal antibody approved for Alzheimer's disease treatment, requires precise and reliable quantification in biological matrices for pharmacokinetic studies. We developed and validated a novel high-performance ...
