  novel aluminum(iii)- and zirconium(iv)-tetraphenylporhyrin (tpp) derivatives are examined as fluoride selective ionophores for preparing polymer membrane-based ion-selective electrodes (ises).   the proof-of-concept of a new methodology for in-line hollow-fiber (hf)-assisted three-phase liquid-phase microextraction (lpme) allowing for handling of the feed and acceptor aqueous solutions and of minute volumes of the organic extracting phase in a programmable flow mode is reported in this paper. The flow analyzer fosters in-line anchoring of ionic-liquid-laden extracting solution (10 .). Analytica chimica acta volume 551, issues 12 , , pages 222-231 kinetic spectrophotometric methods for determination of trimetazidine dihydrochloride. A simple, disposable and inexpensive electrochemical dna biosensor based on a zirconia (zro2) modified thin film screen-printed electrode (zro2spe) has been developed. Short dna sequences (21 monomer units) from the escherichia coli pathogen, modified with a phosphate group at the 5 end, were attached to the surface of the electrode through the affinity of the phosphate group for zirconia. A new pvc membrane electrode for co 2 based on n,n-bis(salicylidene)-3,4-diaminotoluene, an excellent neutral carrier, has been fabricated using sodium tetraphenylborate (natpb) as an anionic excluder and dioctylphthalte (dop) as a solvent mediator. The electrode exhibits a linear potential response in the concentration range of 7. Thermochimica acta publishes original research contributions covering all aspects of thermoanalytical and calorimetric methods and their application to experimental chemistry, physics, biology and engineering. The journal aims to span the whole range from fundamental research to practical application. The journal focuses on the research that advances physical and analytical science of thermal. Over the last twenty years, fluoroquinolones have emerged as one of the most important classes of antibiotics 1. Gemifloxacin mesylate (gfx) (r,s)-7-(4z)-3-(aminomethyl)-4-(methoxyimino)-1-pyrrolidinyl-1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxo-1,8-naphthyridine-3-carboxylic acid mesylate is a fourth generation fluoroquinolone used for the treatment of pneumonia and bronchitis 2. Continued as biochimica et biophysica acta (bba) - general subjects explore journal content latest issue all issues. This study focused on the development of an ednn algorithm for improvement and enhancement of classification and regression performance. We report herein the development of a novel glucose chemiluminescence (cl) biosensor based on covalent immobilization of glucose oxidase (god) in glutaraldehyde-functionalized glass cell and direct coupling of chitosan-induced auag alloy nanoparticles on it, and how it may be useful for determination of glucose due to cl detection of enzymatically generated h2o2.
