Recycling process planning for the End-of-Life management of waste from electrical and electronic equipment

The ever-increasing amount of waste from electrical and electronic equipment (WEEE) has become a common problem due to the significant environmental and health impacts associated with inappropriate End-of-Life (EoL) management. The current ad hoc applications of WEEE recycling are often based on limited knowledge and cannot cope with the complex range of materials and products in such waste. A knowledge-based approach has been utilised to investigate the realisation of a recycling process planner which aims to determine the most suitable EoL options for WEEE. A number of case studies have been used to show that a 20-30% improvement on economical and environmental performance could be achieved through adoption of such a systematic approach to recycling process planning.

A new approach of online waste removal process for laminated object manufacturing (LOM)

A new online de-cubing laminated object manufacturing process which employs self-adhesive sheet with shielding paper is proposed in this paper. The main idea of this new process is to perform bond-then-cut at the same position, avoiding the accumulated error resulted from reposition, and to de-cube the inner waste material in process by peeling off the shielding paper. By doing so, about 30–80% waste material according to various geometric shapes can be removed during the machining process. The new process not only shortens the time for laser cutting and de-cubing, but also enables the production of hollow and shell-shaped parts. Hence, the proposed process promotes both the performance efficiency of laminated process and the manufacturing ability regardless the geometry of the parts.

Effect of carbonation process on the passivating products of zinc in Ca(OH)2 saturated solution

The effect of carbonation process on the passivating layer of zinc in Ca(OH)₂ saturated solution was studied. The investigation was performed by means of corrosion potential, corrosion current density, and impedance measurements. To analyze the changes in the passivating layer, X‐ray diffraction, Raman spectroscopy and scanning electron microscopy (SEM) were utilized. The results obtained indicate that the layer of calcium hydroxyzincate (Ca[Zn(OH)₃]₂ · 2H₂O) (CHZ), which determines the passivity state of zinc both in Ca(OH)₂ saturated solution and in concrete, is destroyed by the carbonation process, in agreement with previous results obtained for galvanized steel embedded in concrete. X‐ray diffractometry and Raman spectroscopy showed that CHZ reaction with CO₂ leads to the formation of Zn₅(CO₃)₂(OH)₆ (hydrozincite) and CaCO₃ (calcite). SEM observation confirms the deep transformation in the passivating layer caused by carbonation. Corrosion potential and corrosion current density measurements show that zinc maintains its passive state also after carbonation. However, impedance measurements indicate that hydrozincite has lower passivating properties than calcium hydroxyzincate in the carbonated solution.     

Effects of atomic relaxation and the electronic structure of niobium (100) and (110) surfaces

A comparative analysis of the atomic relaxation and electronic structure of niobium (100) and (110) surfaces has been carried out using the VASP-PAW method. The relaxation-induced changes in interlayer spacings of surface layers demonstrate an oscillating behavior but they substantially differ for the two analyzed surfaces; namely for the (110) surface with the closest atomic packing two outermost surface layers are contracted by 4.3% and the relaxation becomes noticeable for three outer layers, while for the more “open” (100) surface these quantities equal 13.1 and six layers, respectively. An analysis of the layer-by-layer distribution of the densities of states, spatial distribution of the charge density, and densities of states at the Fermi level indicates that the most considerable changes near Fermi level take place for (100) surface.
