(Springer International Publishing Ag, 2020)Carbon nanotube is one of the important topics of interest in the nanotechnology science. Many scientists have been interested in surface-modified nanotubes for decades. In this study, multi-walled carbon nanotubes (MWCNTs) ... -
New results on discontinuity at fixed point
(Springer Basel AG, 2020)We obtain a Meir-Keeler type fixed-point theorem which gives a new solution to the Rhoades' problem on the existence of contractive mappings that admit discontinuity at the fixed point. Meir-Keeler type solutions of the ... -
Evaluation of Azadirachtin on Arthrospira plantensis Gomont growth parameters and antioxidant enzymes
(EDP Sciences S A, 2020)To understand the effects of contamination of insecticides onphototrophs, and to determine the responses of these organisms against these chemicals are extremely important in understanding how the ecosystem is affected. ... -
Investigation of seasonal and cooking effects on the bioaccessibility of elements in most consumed fish in Turkey
(Central Fisheries Research Inst, 2020)An in-vitro gastrointestinal extraction method has been performed to determine the bioaccessibility of As, Co, Cu, Fe, Mn, Ni, Se and Ti in the most consumed fish (anchovy, bream, sardines, horse mackerel, seabass and ... -
Cost-effective voltammetric determination of boron in dried fruits and nuts using modified electrodes
(Elsevier Sci Ltd, 2020)Cost effective, simple and accurate two voltammetric methods for determination of boron in hazelnut, peanut, almond, raisin, prune and date samples were described. Metal nanoparticles-carbon nanotube modified glassy carbon ... -
Synthesis, characterization, and their some chemical and biological properties of PVA/PAA/nPS hydrogel nanocomposites: Hydrogel and wound dressing
(Sage Publications, 2020)The nanocomposite hydrogels were prepared by dispersing of the nanopomegranate seed particles into poly(vinyl alcohol)/poly(acrylic acid) blend matrix in an aqueous medium by the solvent casting method. These hydrogels ... -
