The probes used are a homologous series of (Phe)3 P+ (CH2)n CH3 (n = 0—5) and tetraphenylphosphonium. The membrane used was an envelope vesicle of Halobacterium hatobium which upon illumination generated the interior-negative membrane potential. In the dark, where no membrane potential was...
1.A solid electric conductor through which an electric current enters or leaves an electrolytic cell or other medium. 2.A collector or emitter of electric charge or of electric-charge carriers, as in a semiconducting device. American Heritage® Dictionary of the English Language, Fifth Edition....
Table1. Inset: cyclic voltammograms of ferrocene in the given electrolytes. We addedx-axis breaks of 2.4 V to highlight bothELi(0 V) and the redox potentials of ferrocene in the two electrolytes. The shift ofELi(over 0.6 V), which influences the CEs of Li-metal anodes, strongly ...

In an electrochemical cell, the electrode whose potential remains constant when the current flows is known as the reference electrode, and it allows a proper investigation of the system by the analysis of the potential difference between this electrode and a second electrode. In order to best ...
Initial electrode potentials and the electrode conditioning process. As listed in Table 1, the MCVs of asymmetrical supercapacitors are generally larger than those of the symmetrical counterparts. These increases can be broadly attributed to the use of a different material for the negative electrode ...
Solar cell efficiency increased from 6.02 % (using pure vein graphite) to 7.95 %, representing 86 % of the efficiency attained with a Pt electrode (9.25 %). This notable 32 % efficiency enhancement is attributed to the highly porous nanostructure of the graphite/SnO2 composite, offering ...
