National Office of Measures, Budapest, Hungaiy A new method for the absolute determination of electrolytic Conductivity based on direct current and potcntiomctrlc measurements is described. The unique design of the cell uses a removable center section whose length and crosS'Seciional area arc accurately known. Two pairs of matched Ag, AgCI electrodes are used in a four terminal mode of resistan...

In the search for greener treatment technologies, this work studies the coupling of a wind turbine energy supply with an electrolytic cell (CWTEC device) for the remediation of wastewater polluted with pesticide 2,4-dichlorophenoxyacetic acid (2,4-D). The discontinuous and unforeseeable supply of energy is the main challenge inspiring this new proposal, which aims at reducing the environmental ...

Electrolytic and metallized polypropylene film (MPPF) capacitors are among the most popular capacitors used in electronic equipments. The choice of capacitors is of major importance because one of the most frequent causes of the equipment breakdowns results from the failure of capacitors, and will therefore determine the overall lifetime of the system. Electrolytic capacitors present higher cap...

During the past decay many experimental configurations to improve yield of hydrogen by electrolysis. These attempts include tests different materials for electrodes. This study proposes use γ-radiation waste sources nuclear reactors. The related configuration can be reduced boxes filled with water exposed ionizing radiation and capacitors as electrodes well-known in other technical disciplines....

oxidation on Ti6Al4V S Leal Marin1, H Carreño Garcia2, P Escobar Rivero2, H Estupiñan Duran1. 1 Tribology and surfaces group, Universidad Nacional de Colombia sede Medellín, Colombia 2 Research Center on Tropical Diseases, Universidad Industrial de Santander, Bucaramanga, Colombia. Statement of Purpose: Coatings over Ti6Al4V are extensively studied to improve the compatibility and mechanical pr...

The problems of blending electrolyzer and multi-constraint optimization of electrolytic aluminum scheduling in the electrolytic aluminum production process were addressed. Based on a mathematical model analysis, a novel hybrid optimization algorithm is proposed for optimization of blending together the molten aluminum in different electrolytic cells. An affinity degree function was designed to ...

This work presents techno-economic modelling of four thermochemical technologies that could produce nearly 20,500 tonnes hydrogen per year from biomass for public bus transport. These included fluidised bed (FB) steam gasification, fast pyrolysis-FB pyrolysis-steam reforming, and reforming biogas anaerobic digestion (AD). Each plant was modelled on ASPEN plus with without carbon capture storage...
