“…Na reciclagem, a etapa da coleta, segundo Silva et al (2003) e Coelho, Castro e Junior (2011), é tida como o alicerce do processo e consiste na separação dos materiais em sua origem ou captação com posterior envio para etapas posteriores. No estágio de separação, o material pode ser identificado pela simbologia contida no produto acabado ou pela utilização de testes de caracterização, tais como por densidade (PONGSTABODEE; Kunachitpimol; Danribgkerd, 2008), flotação (SHENT; PUGH; FORSSBERG, 1999), características triboelétricas (DODBIBA et al, 2005). Por exemplo, a simbologia designada pela norma NBR 13.230 (ABNT, 2008), da Associação Brasileira de Normas Técnicas (ABNT), representa o PET com setas na forma de triângulo e o número "1" no seu interior.…”

“…The charge interactions within the Debye length were accounted for from the diode surface (acrylonitrile-butadiene-styrene, ABS) and the glass substrate, whereas the plasma-treated PDMS channel walls are free of charge. 45 Even though negative surface charges on the glass substrate and the diode ABS surfaces are known to be weakly conducting, 29,46,47 positive charges in the electrolyte (KCl, NaCl, or culture medium) will be attracted to the negatively charged surface, resulting in negative charges moving toward the positive tip of the diode, i.e., the direction of EOS flow.…”

An electro-osmosis (EOS) diode pumping platform capable of culturing cells in fluidic cellular micro-environments particularly at low volume flow rates has been developed. Diode pumps have been shown to be a viable alternative to mechanically driven pumps. Typically electrokinetic micro-pumps were limited to lowconcentration solutions ( 10 mM). In our approach, surface mount diodes were embedded along the sidewalls of a microchannel to rectify externally applied alternating current into pulsed direct current power across the diodes in order to generate EOS flows. This approach has for the first time generated flows at ultra-low flow rates (from 2.0 nl/s to 12.3 nl/s) in aqueous solutions with concentrations greater than 100 mM. The range of flow was generated by changing the electric field strength applied to the diodes from 0.5 Vpp/cm to 10 Vpp/cm. Embedding an additional diode on the upper surface of the enclosed microchannel increased flow rates further. We characterized the diode pump-driven fluidics in terms of intensities and frequencies of electric inputs, pH values of solutions, and solution types. As part of this study, we found that the growth of A549 human lung cancer cells was positively affected in the microfluidic diode pumping system. Though the chemical reaction compromised the fluidic control overtime, the system could be maintained fully functional over a long time if the solution was changed every hour. In conclusion, the advantage of miniature size and ability to accurately control fluids at ultra-low volume flow rates can make this diode pumping system attractive to lab-on-a-chip applications and biomedical engineering in vitro studies.
