We present a theoretical description of the kinetics of electrochemical charge transfer at single-walled carbon nanotube (SWNT) electrodes, explicitly taking into account the SWNT electronic band structure. SWNTs have a distinct and low density of electronic states (DOS), as expressed by a small value of the quantum capacitance. We show that this greatly affects the alignment and occupation of ...

n-Glucose-6-phosphate dehydrogenase (Zwischenferment) was discovered by Warburg and Christian in 1931 (1, 2). An active preparation was obtained then from horse erythrocytes and in 1932 from the Lebedev juice made from brewers’ yeast (3). Because of its extreme specificity, this enzyme has become an important analytical tool. Various preparations of it have been described, the first being those...

Measurements of the reorganization energies (λ) and the maximum values of the electron transfer rate constants (kapp , obtained for -η g 2λ) of two redox probes at monolayer-coated electrodes are used as diagnostic parameters of the location of a probe at the monolayer/solution interface. Kinetics of the electroreduction of IrCl6 and FcCH2N(CH3)3 at hexadecanethiolate-coated Hg drop electrodes ...

14 The development and status of what is commonly called the Gerischer mechanism of silicon etching in 15 fluoride solutions is reviewed. The two most widely used and studied wet etchants of silicon are F 16 and OH . Their mechanisms of atom removal share many things in common; in particular, chemical pas17 sivation by a hydrogen-terminated surface plays an important role in both. Crucially, ho...

Two genes from Clostridium acetobutylicum DSM 792 were identified which are predicted to encode new members of the ECF subfamily of eubacterial RNA polymerase sigma factors. The sigX gene has the potential to encode a 184-amino acid protein with a molecular mass of 21,870 Da and with the highest overall similarity to Fecl of Escherichia coli (27 % identical residues). The second gene, which is ...

The reduction of the electrochemical window (EW) electrolytes plays a significant role in assessing their compatibility with anode lithium-ion batteries. However, accurate calculation EW is still challenging due to missing solvation effects, condensation kinetic factors, and passivation on anodes. theoretical prediction intrinsic apparent confirmed by comprehensive experimental analysis ethylen...

Electrodialysis is an innovative technique to reclaim phosphates from municipal wastewater. However, chemical reactions accompany the transport of these ions through ion-exchange membranes. The present study investigates dependence phenomena on initial pH and concentration phosphate-containing solution using a heterogeneous anion-exchange membrane. Linear sweep voltammetry, electrochemical impe...
