Abstract With the increasingly high requirements on appearance of electronic equipment and environmental protection, conventional chromate chemical conversion coatings aluminum alloys gradually showed some shortcomings, such as color difference in harm to human health environment process. In this paper, three kinds environment-friendly colorless (LANTH-613, ALTRCHR-250, YMT-631) were prepared b...
As public concern mounts over exposures to ionizing radiation stemming from environmental releases of radionuclides following nuclear accidents, there is a growing need to develop reliable techniques that reconstruct exposures and doses to individuals. Especially in situations where conventional dosimeters were not in place at the time of facing to radiation exposure. In order to provide guidan...

in this work, a tracer study on pore initiation in anodic alumina in oxalic acid was performed. effects of some experimental parameters such as applied electrical potential, electrolyte composition and heat pretreatment were evaluated. electrochemical and morphological experiments were performed using potentiostatic anodizing and scanning electron microscopy (sem) techniques, respectively. effe...
Waste electrical and electronic equipment is one of the major world-wide waste streams triggering the emergence of environmental strategies. Environmental regulations, closed-loop supply chain (CLSC) activities and design-for-environment (DfE) practices are environmental friendly strategies being implemented by governments and industry. In this paper, we apply a System Dynamics model to a CLSC ...
Two regulations, The Control of Wastage of Electrical and Electronic Equipment, and Directives Restricting the Use of Hazardous Substances, adopted by the European Union in 2002 and 2003 respectively, control the sale of electrical and electronic equipment in all 25 nation members and these regulations are going to influence other countries in the world. Giving increasing global awareness of th...
