Iron-substituted AB5-type MH electrode

Anisotropy of Ruthenium-substituted Yttrium-iron-garnet

Electrode reactions of iron oxide-hydroxide colloids.

Small-sized FeO(OH) colloids stabilised by sugars, commercially available for the clinical treatment of iron deficiency, show two waves during cathodic polarographic sweeps, or two current maxima with stationary electrodes, in neutral to slightly alkaline aqueous medium. Similar signals are observed with Fe(III) in alkaline media, pH > 12, containing citrate in excess. Voltammetric and polarogr...

and fungi, are vital to the function of all ecosystems. This is largely because they exist in enormous numbers (there are roughly 5 × 10 bacteria alone worldwide) and so have immense cumulative mass and activity. They are also probably more diverse than any other organisms, so it is easy to see why the structure of microbial communities, that is, the different kinds of organisms and their abund...

microscopic, eukaryotic phytoplankton known as diatoms. These photosynthetic workhorses are found in waters worldwide, wherever there is sufficient light and nutrients. Their name is derived from the Greek diatomos, meaning ‘cut in half ’, a reference to their distinctive two-part cell walls made of silica (Fig. 1). Each year, diatom photosynthesis in the sea generates about as much organic car...

Process analysis of electroless copper plating for AB5- type hydrogen storage alloy using support vector regression

Surface modification is an effective method to improve the electrochemical property of hydrogen storage alloy. In order to investigate the influence of process factors of electroless copper (Cu) plating for AB5-type hydrogen storage alloy on Cu coating mass, a novel modeling approach, support vector regression (SVR) combined with particle swarm optimization (PSO), was proposed to construct a ma...
