Production and application of highly efficient and reusable palladium nanocatalyst decorated on the magnetically retrievable chitosan/activated carbon composite microcapsules
(Springer, 2019)
This study reports (i) the production of magnetically retrievable microcapsules as immobilizing agents, which are composed of chitosan/activated carbon composite (CS-AC/Fe3O4), (ii) the green synthesis of highly stable ...
Extraction and characterization of chitin and chitosan with antimicrobial and antioxidant activities from cosmopolitan Orthoptera species (Insecta)
(Korean Soc Biotechnology & Bioengineering, 2015)
This study examined two gregarious Orthoptera species (Calliptamus barbarus and Oedaleus decorus) as potential sources of chitin. The chitin content of the dry weight of C. barbarus was 20.5 +/- 0.7%, and it was 16.5 +/- ...
A new chitosan Schiff base supported Pd(II) complex for microwave-assisted synthesis of biaryls compounds
(Elsevier Ltd., 2017)
In this study, a new heterogeneous palladium (II) catalyst that contains O-carboxymethyl chitosan Schiff base has been designed for Suzuki coupling reactions. The chemical structures of the synthesized catalyst were ...
Extraction and characterization of alpha-chitin and chitosan from six different aquatic invertebrates
(Springer, 2014)
Chitin and chitosan were extracted from six different aquatic invertebrate species. Species dry weights varied between 5 % and 20 % chitin, and the chitosan productivity of these chitins varied between 66 % and 74 %. Chitin ...
Bat guano as new and attractive chitin and chitosan source
(BioMed Central Ltd., 2014)
Introduction: Chitin is a biopolymer that forms the exoskeleton of arthropods, and is found in the cell walls of fungi. It has a wide range of uses in fields such as cosmetics, pharmacy, medicine, bioengineering, agriculture, ...
New chitin, chitosan, and O-carboxymethyl chitosan sources from resting eggs of Daphnia longispina (Crustacea); with physicochemical characterization, and antimicrobial and antioxidant activities
(Korean Soc Biotechnology & Bioengineering, 2014)
The paper describes the isolation and characterization of chitin and chitosan from Daphnia longispina resting eggs harvested from a reservoir. Resting eggs are fertilized eggs that are encased in chitinous shells called ...
An environmental catalyst derived from biological waste materials for green synthesis of biaryls via Suzuki coupling reactions
(Elsevier Science Bv, 2016)
Synthesis of bio-macromolecular supported catalysts has gained much recent attention due to their greener nature. Among the biopolymers, chitosan is widely used as a support material due to its high affinity for metal ions. ...
Microwave assisted synthesis of biarlys by C-C coupling reactions with a new chitosan supported Pd(II) catalyst
(ELSEVIER SCIENCE BV, 2016)
In this study a new type chitosan-based support has been produced for Pd(II) catalyst and its catalytic performance in Suzuki C-C reactions has been studied under microwave irradiation without using any solvent. The chemical ...
Sustainable chitosan/starch composite material for stabilization of palladium nanoparticles: Synthesis, characterization and investigation of catalytic behaviour of Pd@chitosan/starch nanocomposite in Suzuki–Miyaura reaction
(Wiley, 2018)
We fabricated a green chitosan/starch composite as support material for stabilization of palladium nanoparticles for the first time. The chemical structure of the sustainable palladium nanocomposite was investigated using ...
Highly active and robust palladium nanoparticles immobilized on biodegradable microcapsules containing chitosan-guar gum composite for synthesis of biaryl compounds
(Selçuk Üniversitesi, 2020)
In this study, highly stable biodegradable microcapsules, which are composed of chitosanguar gum composite (CS-GG), were prepared as catalyst support. Then, palladium nanoparticles were
successfully decorated on the ...
