Solid phase diffusivity Ds is a key parameter in Lithium-Ion cell models because solid phase diffusion typically dominates the voltage transients. The Galvanostatic Intermittent Titration Technique (GITT) is easy to implement and universally accepted as the standard for diffusivity measurement, but the accuracy of GITT diffusivity measurement is unknown. This paper develops a Least Squares GITT...

This paper focuses on the galvanostatic magneto-electrodeposition of Ni-Co alloys in dimethyl sulphoxide (DMSO) in the presence and absence of a permanent parallel magnetic field (PPMF) to the cathode surface. It was found that the mass deposition was enhanced in the presence of PPMF (9 T) compared with the deposition without PPMF. The percentage enhancement potential ( %) was elevated ( 5% = 2...

A variation of an electrochemical time-of-flight (ETOF) technique is described and illustrated with the test cases involving electrochemically generated Ag and H ions in aqueous solutions of different viscosity and ionic strength. Similar to the earlier ETOF methods, the new ETOF technique also relies on photolithographically fabricated microelectrode devices. It uses a constant current (rather...

The kinetics of H(D) absorption into a b-phase PdHx (PdDx) electrode are discussed numerically, based on the Volmer–Tafel route of the hydrogen (deuterium) evolution reaction and thermodynamic and kinetic data of H(D) in the b-phase PdHx (PdDx). It is found that the asymptotic loading ratio of H(D) is determined only by the Tafel step under galvanostatic conditions. The kinetics of H(D) absorpt...

A sensitive and reliable potentiometric biosensor for determination of penicillin has been developed by exploiting the self-limiting growth of the non-conducting polymer, polytyramine. Optimum polytyramine-penicillinase (PTy-PNCnase) films for potentiometric detection of penicillin were accomplished with monomer solutions which contained 0.03 M tyramine, 37 U/mL penicillinase, 0.01 M KNO3, and ...

In this work, nanoflower-like MoS2 grown on the surface of multi-walled carbon nanotubes (MWCNTs)/polyaniline (PANI) nano-stem is synthesized via a facile in situ polymerization and hydrothermal method. Such a novel hierarchical structure commendably promotes the contact of PANI and electrolyte for faradaic energy storage. In the meanwhile, the double-layer capacitance of MoS2 is effectively us...

The electrooxidation of aqueous solutions containing 5mM of o-, m- and p-cresol at pH 4.0 has been investigated using a flow filter-press reactor with a boron-doped diamond (BDD) under galvanostatic electrolysis. All cresols are degraded at similar rate up to attaining overall mineralization. Comparable treatment of the m-cresol effluent on PbO(2) leads to partial electrochemical incineration. ...

TiO2-WO3 hybrid photocatalysts were prepared using wet-chemical technique, and their energy storage performance was characterized by electrochemical galvanostatic method. TiO2 powder was coupled with WO3 powder, which was used as electron pool and the reductive energy could be stored in. As a result, the prepared TiO2-WO3 had good energy storage ability while pure TiO2 showed no capacity and pu...

3-Methyl-1-phenyl-1,5-dihydro-pyrazolo[3,4-d]pyrimidine-4-thione was prepared and used as a key compound for the preparation of some S-acyclic nucleosides of pyrazolo[3,4d]pyrimidine-thiones. Furthermore, the corrosion inhibitions of the prepared compounds towards carbon steel corrosion by 1.0 M hydrochloric acid were evaluated by chemical and electrochemical methods. The effect of inhibitors c...

The effect of three compounds of non ionic surfactants, namely, ethoxylated fatty amines with different number of ethylene oxide unit on the corrosion of carbon steel (Type L52) in 1 M HCl has been studied using weight loss and galvanostatic polarization measurements. The percentage inhibition efficiency was found to increase with increasing concentration of inhibitor, number of ethylene oxide ...
