a highly selective electrode for bromide ion based on aza pyrilium derivative as an excellentionophore is described.the sensor exhibits a good linear response with a slope of ( 60±1 ) mv per decadeover the concentration range of ( 1×10-3 – 9×10-6 m ) , and a detection limit of ( 3×10-6 m ) of bromideions .the electrode response is independent of ph in the range of(4.0 –9.5).selectivity coeffici...

in this research, a pvc membrane electrode for manganese (ii) ions based on n-(2-picolinamidoethyl)picolinamide as neutral carrier was prepared. the electrode exhibits a nemstian responseover mn(ii) concentration range of (1.0 x10-5 t01.0 x 10-1m) with a slope of 29.3±0.5 mv perdecade of concentration with a working ph range of 4.0-9.0. it has a fast response time (

Herein, fast Fourier transformation square-wave voltammetry (FFT-SWV) as a novel electrochemical determination technique was used to investigate the electrochemical behavior and determination of Riboflavin at the surface of a nanocomposite modified carbon paste electrode. The carbon paste electrode was modified by nanocomposite containing Samarium oxide (Sm2O3)/reduced gra...

The common techniques to improve hydrogel's mechanical properties include increasing crosslinking density and forming crosslinked double-network hydrogel, which may cause some hydrogels lose their smart functionalities. Inspired by entanglement-induced strengthening, a simple approach introducing hydroxypropyl cellulose (HPC) fibers entangled with different hydrogel matrix systems are reported....
