A new approach to the Assad-Kirk fixed point theorem
(Springer Basel Ag, 2016)
In the present paper, considering the Wardowski's technique, we give a new approach to the Assad-Kirk fixed point theorem on metrically convex metric spaces. We also provide a nontrivial example showing that our result is ...
Fixed point and homotopy results for multivalued maps satisfying an implicit relation
(Birkhauser Verlag Ag, 2011)
We present some common fixed point theorems for multivalued maps satisfying an implicit relation on complete metric spaces. Also a homotopy result is given for multivalued maps.
Synthesis and biological evaluation of novel urea, thiourea and squaramide diastereomers possessing sugar backbone
(ELSEVIER SCI LTD, 2020)
A series of novel chiral 14 urea, thiourea and squaramide stereoisomers possessing carbohydrate backbones as well as amide functional groups was synthesized and characterized by their, H-1 NMR, C-13 NMR, FT-IR, HRMS, optical ...
Thermoresponsive and biocompatible poly(vinyl alcohol)-graft-poly(N,N-diethylacrylamide) copolymer: Microwave-assisted synthesis, characterization, and swelling behavior
(Wiley, 2018)
Novel thermoresponsive poly(vinyl alcohol)-graft-poly(N,N-diethylacrylamide) (PVA-g-PDEAAm) copolymers were prepared by microwave-assisted graft copolymerization using a potassium persulfate/N,N,N,N-tetramethylethylenediamine ...
Synthesis and characterization of pH- and temperature-sensitive materials based on alginate and poly(N-isopropylacrylamide/acrylic acid) for drug delivery
(Springer, 2016)
The significant developments in the field of polymer have advanced the synthesis of polymer-based materials and have expanded their use in a wide variety of applications. Today, polymers can be designed to change their ...
Influence of ruthenium alkylidene complexes bearing tricyclohexylphosphine or 3-bromopyridine ligand on the properties of fluorine containing polymers
(Springer, 2013)
The catalytic performance of ruthenium alkylidene complexes bearing tricyclohexylphosphine or 3-bromopyridine ligand in the ring opening metathesis polymerization (ROMP) of fluorine containing monomers, exo-N-4-fluorophe ...
Covalent immobilization of lipase onto hydrophobic group incorporated poly(2-hydroxyethyl methacrylate) based hydrophilic membrane matrix
(Elsevier Sci Ltd, 2002)
In this study, a hydrophobic group containing monomer, 2-methacrylamidophenyalanine (MAPA) was prepared by using methacrylochloride and phenylalanine. Then, poly(2-hydroxyethyl methacrylate-co-methacrylamido-phenlyalanine) ...
Preconcentration and electroanalysis of silver at pt electrode modified with poly(2-aminothiazole)
(Maik Nauka/Interperiodica/Springer, 2013)
Conducting poly(2-aminothiazole) (PAT) films were electrodeposited on a platinum disc electrode surface by constant potential electrolysis of 2-aminothiazole (AT) for the stripping voltammetric determination of Ag(I). Ag(I) ...
Determination of Cu, Zn and Cd in water by FAAS after preconcentration by baker's yeast (Saccharomyces cerevisiae) immobilized on sepiolite
(Springer Verlag, 1999)
By using the adsorbent Saccharomyces cerevisine immobilized on sepiolite an adsorption-elution method was developed for the preconcentration of Cu, Zn, and Cd followed by flame atomic absorption spectrometry (FAAS). ...
