Functionalized rGO-Pd nanocomposites as high-performance catalysts for hydrogen generation via water electrolysis
(Elsevier Ltd, 2022)
Designing an efficient electrocatalyst for hydrogen evolution reaction (HER) is an important research area among the energy-related topics. In our study, the surface of the glassy carbon electrode (GCE) has been modified ...
Synthesis and characterization of water soluble O-carboxymethyl chitosan Schiff bases and Cu(II) complexes
(Elsevier, 2015)
In this study, mono-imine was synthesized (3a and 4a) via a condensation reaction between 2,4-pentadion and aminobenzoic acid (meta or para) in alcohol (1:1). The second-imine (CS-3a and CS-4a) was obtained as a result of ...
Highly efficient Suzuki cross-coupling reaction of biomaterial supported catalyst derived from glyoxal and chitosan
(Elsevier Science Sa, 2016)
In this study a new chitosan based water soluble Schiff base was produced through carboxymethylation of chitosan and its Pd(II) complex were synthesized and characterized by FTIR, H-1 NMR, C-13 CP-MAS NMR, TG/DTG, SEM/EDAX, ...
Green heterogeneous Pd(II) catalyst produced from chitosan-cellulose micro beads for green synthesis of biaryls
(Elsevier Ltd., 2016)
In green catalyst systems, both the catalyst and the technique should be environmentally safe. In this study we designed a green palladium(II) catalyst for microwave-assisted Suzuki C C coupling reactions. The catalyst ...
Physicochemical comparison of chitin and chitosan obtained from larvae and adult Colorado potato beetle (Leptinotarsa decemlineata)
(Elsevier Science Bv, 2014)
Chitins and chitosans obtained from larva and adult Coloradopotato beetles (Leptinotarsa decemlineata) were physico-chemically characterized and differences between adults and larvae were identified. The dry weight chitin ...
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 ...
Carboxymethyl chitosan schiff base supported heterogeneous palladium(II) catalysts for suzuki cross-coupling reaction
(Elsevier Science Bv, 2015)
In this study, two new O-carboxymethyl chitosan Schiff bases supported Pd(II) catalyst were synthesized (OCMCS-3aPd and OCMCS-4aPd). The catalysts were characterized with FTIR, TG/DTG, SEM/EDAX, XRD, ICP-OES, UV vis, ...
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, ...
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 ...
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 +/- ...
