Cyanation of aryl halides and Suzuki-Miyaura coupling reaction using palladium nanoparticles anchored on developed biodegradable microbeads
(Elsevier B.V., 2020)
This work reports i) green synthesis of palladium nanoparticles (Pd NPs) on the developed biodegradable microbeads as stabilizers, featuring chitosan, agarose and beta-cyclodextrin, ii) investigation of the catalytic role ...
Cu(II) and Pd(II) complexes of water soluble O-carboxymethyl chitosan Schiff bases: Synthesis, characterization
(Elsevier Science Bv., 2015)
This study reports the synthesis of two new water soluble O-carboxymethyl chitosan Schiff bases (OCMCS-5 and OCMCS-6a) and their Cu(II) and Pd(II) complexes. Characterizations of these complexes were carried out with FTIR, ...
Pd NPs@Fe3O4/chitosan/pumice hybrid beads: A highly active, magnetically retrievable, and reusable nanocatalyst for cyanation of aryl halides
(Elsevier Ltd, 2020)
In this study, Fe3O4/chitosan/pumice hybrid beads were developed as a new stabilizer agent, and palladium nanoparticles (Pd NPs) were successfully decorated on the designed stabilizer without adding any toxic reducing ...
The impact of pH and biopolymer ratio on the complex coacervation of Spirulina platensis protein concentrate with chitosan
(Springer, 2021)
Spirulina platensis is one of the most significant multicellular blue-green Cyanobacterium microalgae with a high protein content. The complex coacervation as an encapsulation technique allows the formation of proteins ...
The effect of chitosan coating and vacuum packaging on the microbiological and chemical properties of beef
(Elsevier Ltd, 2020)
Beef is an animal food sensitive to deterioration due to its rich nutrient content. Therefore, some preservation techniques are applied. These include vacuum packaging, a modified atmosphere, a controlled atmosphere and ...
Design of nanostructured palladium catalyst supported by chitosan/Co3O4 microspheres and investigation of its catalytic behavior against synthesis of benzonitriles
(Elsevier B.V., 2021)
Designing of eco-friendly, low cost, and thermally stable stabilizing/supporting agents are always desired for production of catalyst systems which provide good catalytic performance in organic reactions. In this study, a ...
Evaluation of the effect of chitosan coating on microbiological and oxidative properties of refrigerated beef
(Gıda Teknolojisi Derneği, 2020)
Beef is an animal food sensitive to deterioration with short shelf-life due to its rich nutrient content. Many studies concerned with the use of edible coating are carried out to increase the shelf life of beef. In this ...
Dermestes ater pupasından elde edilen kitosanın deri kanseri üzerine etkisi
(Aksaray Üniversitesi Fen Bilimleri Enstitüsü, 2021)
Kitin β- (1 → 4) bağlantılı iki N- asetil D Glukozamin birimlerinden meydana gelen polisakkarit esaslı bir biyopolimerdir. Selülozdan sonra dünya genelinde en bol bulunan polimerdir. Kitosan ve türevleri; antikanser, toksik ...
Production of Pd nanoparticles embedded on micro-sized chitosan/graphitic carbon nitride hybrid spheres for treatment of environmental pollutants in aqueous medium
(Elsevier Ltd, 2021)
The presence of various organic contaminants such as toxic nitro compounds and dyes in water/wastewater poses a major problem for the environment and human health. Therefore, the treatments of these pollutants are of vital ...
Physicochemical characterization of chitin and chitosan obtained from resting eggs of ceriodaphnia quadrangula (branchiopoda: Cladocera: daphniidae)
(Crustacean SOC, 2014)
Chitin and chitosan were produced from the structures of the resting eggs of Ceriodaphnia quadrangula (Muller, 1785), of which tons are naturally produced in a dammed lake. On a dry weight basis, 16-17% chitin and 11% ...
