A new salicylate-selective electrode based on the complex N,N'-1,4-butylene bis(3-methyl salicylidene iminato) copper(II) as the membrane carrier was developed. The electrode exhibits a good Nernstian slope of 59.1 ${\pm}$ 1.0 mV/decade and a linear range of $1.0\;{\times}\;10^{-6}$-1.0 M for salicylate. The limit of detection was $5.0\;{\times}\;10^{-7}$ M. It has a fast response time 10 s and can be used for more than three months. The selective coefficients were determined by the fixed interference method (FIM) and could be used in the pH range 4.5-10.5. It was employed as an indicator electrode for direct determination of salicylate in pharmaceutical samples.
Application of Nanofibers Based on Natural Materials as Catalyst in Organic Reactions

Up to the present, nanofibers have been prepared from an assortment of materials, such as naturalpolymers, carbon-based nanomaterials, semiconducting nanomaterials, and composite nanomaterials. Producing composite nanofibers from biological template materials (e.g. peptides, proteins, polymers,carbohydrate, virus, bacteral cellulose etc.) as novel nanostructures and biological materials has attractedresearchers due to their potential applications in tissue engineering, drug delivery, regenerativemedicine, biosensing, sensors, andfilter air pollutants, and also because of their unique properties suchas the high surface area and porosity and good biocompatibility. In this sense, there has been a great focuson the catalytic activity of nanofibers due to the unique properties i.e. high catalytic efficiency, stabilizingmetal nanoparticles, preventing aggregation of the nanoparticles and high specific surface area. Thus, inthis review, we focus on two topics: (1) the preparation methods of nanofibers, nanorods and whiskers(2) the investigations of various nanofibers, nanorods and whiskers catalytic materials in theelectrocatalyst, photocatalyst, organo catalyst, thermal catalysis and morphology as well as relatedcatalytic mechanisms are summarized and discussed.
