Water lily (Eichhornia crassipes) generation of electricity through photosynthesis

Generate electricity through the photosynthesis of the water lily; releasing electrons at their roots, to be collected by the anode (copper wire) and cathode (metallic foil) conductors, to transport them through copper conductors and be able to use them, in light energy, in a 3-volt led. Plastic containers on average have a higher voltage, compared to metal containers, on average they reached 0.747 volts, R6 was the one with the highest voltage production and the lowest 0.518 volts on average was R4. The voltage produced by metal containers, which did not reach the maximum values of plastic containers, the highest average is R7, with a voltage of 0.576 volts and the lowest of all averages is 0.216 volts R10, On 09/17/2019 at 4:45 PM, the highest average voltage of 7.11 volts was recorded.

Structural Analysis of the Selected Products From the Suspension Furnace Produced in the Internal Recycling

There are presents the internal recycling in anode furnace, in addition to mainly blister copper and converter copper. During the process there arise the two types of semi-finished products intended for further pyro metallurgical processing: anode copper and anode slag. The stream of liquid blister copper enters into the anode furnace treatment, in which the losses are recovered, e.g. copper, resulting from oxidation and reduction of sulfides, oxides and the oxidation of metallic compounds of lead, zinc and iron. In the liquid phase there are still gaseous states, which gives the inverse relationship relating to the solid phase, wherein the gases found an outlet in waste gas or steam. The results of chemical analysis apparently differ from each other, because crystallite placement, the matrix structure and the presence of other phases and earth elements are not compared, which can be regained in the process of electrorefining. One should not interpret negatively smaller proportion of copper in the alloy, since during the later part of the production more elements can be obtained, for example from sludge, such as platinum group metals and lanthanides. According to the research the quality of blister copper, to a large extent, present in the alloy phase to many other elements, which can be recovered.

Lithium-Ion Battery Anode Based on Thinning Si Microchannel Plate Coated with Copper Current Collector

In this paper, chemical etched Si microchannel plates (Si-MCPs) is fabricated to use as lithium-ion battery anode. Copper formed by chemical deposition was served as current collector. The chemical etched Si-MCP with copper current collector exhibited a better cycle performance in the galvanostatic charge-discharge measurements. The reaction mechanism was also investigated based on cyclic voltammetry test.

Electrochemical Migration Characteristics of Ag-Plated Cu Powders in Conductive Thick Film

Silver electrochemical migration results in the degradation of surface insulation resistance, and has been attributed to the dendritic bridge between adjacent conductors. In this paper, the electrochemical migration behavior of both Ag-plated Cu powder and pure silver powder in conductive thick film (CTF) are investigated. By Electrochemical migration test (water drop+ DC bias method), and the SEM and XRD examinations, it was found that the silver electrochemical migration in CTF was minimized when the Ag-plated Cu powder substitute silver powder in CTF. This is ascribed to the galvanic coupling effect that plays an important role in the migration inhibition. As sacrifice anode copper restrains the cathodic silver from dissolving in solution so as to decreases the probability of dendritic growth.

The effect of bi presence as impurities in anodic copper on kinetics and mechanism of anodic dissolution and cathodic deposition of copper

The influence of Bi, as foreign metal atoms in anode copper, on kinetics and mechanism of anodic dissolution and cathodic deposition of copper in acidic sulfate solution was investigated using the galvanostatic single-pulse method. Results indicate that presence of Bi atoms in anode copper increases the exchange current density, as determined from the Tafel analysis of the electrode reaction, which is attributed to the increase of the crystal lattice parameter determined from XRD analysis of the electrode material.

The effect of antimony presence in anodic copper on kinetics and mechanism of anodic dissolution and cathodic deposition of copper

The influence of the presence of Sb atoms, as foreign metal atoms in anode copper, on kinetics, and, on the mechanism of anodic dissolution and cathodic deposition of copper in acidic sulfate solution has been investigated. The galvanostatic single-pulse method has been used. Results indicate that presence of Sb atoms in anode copper increase the exchange current density as determined from the Tafel analysis of the electrode reaction. It is attributed to the increase of the crystal lattice parameter determined from XRD analysis of the electrode material.
