Direct Electrochemistry of Porcine Purple Acid Phosphatase (Uteroferrin) [PDF]

open access: yesBiochemistry, 2004
Cyclic voltammetry of the non-heme diiron enzyme porcine purple acid phosphatase (uteroferrin, Uf) has been reported for the first time. Totally reversible one-electron oxidation responses (FeIII-FeII --> FeII-FeIII) are seen both in the absence and in the presence of weak competitive inhibitors phosphate and arsenate, and dissociation constants of ...

Review on Multi-Scale Models of Solid-Electrolyte Interphase Formation [PDF]

open access: yes, 2018
Electrolyte reduction products form the solid-electrolyte interphase (SEI) on negative electrodes of lithium-ion batteries. Even though this process practically stabilizes the electrode-electrolyte interface, it results in continued capacity-fade ...

Immobilization of Cytochrome c on Multi-Walled Carbon Nanotube-Poly(Vinysulfonic Acid) Composite Film and Its Application for Amperometric Determination of H2O2

open access: yesInternational Journal of Electrochemical Science, 2011
We report the immobilization of Cytochrome c (Cyt c) on multi-walled carbon notube-poly(vinyl sulfonic acid) (MWCNT-PVS) composite film modified glassy carbon electrode (GCE) and its application as H2O2 sensor. The MWCNT-PVS film is a good matrix for the

Voltammetric determination of the critical micellar concentration of surfactants by using a boron doped diamond anode [PDF]

open access: yes, 2010
The electrochemistry of three surfactants has been studied by voltammetry at boron doped diamond (BDD) electrode in sodium sulphate solutions. The electrochemical behaviour of these surfactants is characterized by an oxidation signal (peak or wave ...
