  • Evolution of industrial symbiosis in an eco-industrial park in China

    Yu, Fei   Han, Feng   Cui, Zhaojie  

    Industrial symbiosis and eco-industrial park have been developed for decades and have significant economic and environmental effects in China. To research the evolution of industrial symbiosis and eco-industrial park construction, and summary the drivers and characteristics of industrial symbiosis development in China, this study,uses the National Demonstration Eco-Industrial Park, namely, the Rizhao Economic and Technology Development Area (REDA), as a case study to introduce the industrial symbiosis development process and to research the evolution of industrial symbiosis and eco-industrial park construction, and summarizes the drivers and characteristics of industrial symbiosis development in China. Based on in-depth investigation of enterprises and the government in REDA, three stages (1991 2002, 2003-2006, 2007-2011) of industrial symbiosis development are identified, 31 inter-firms symbiosis performances involving cereal oil and food, machinery, pulp and paper, textile and garment, wine refining, and biochemical industries were formed since REDA was founded in 1991. Results show the environmental benefits of industrial symbiosis performances in 2011, and argue that economic benefits, mainly resulted from stricter environmental standards, tax preference, benefits from material substitution, and financial subsidies, is the critical driver for the stakeholders to participate in industrial symbiosis. The action of governments in industrial symbiosis development is to constituting strict environmental standards, resource comprehensive utilization schemes, financial support and circular economy and eco-industrial park planning guidance. This article provides some unique characteristics of industrial symbiosis growth in a developing country from enterprises and government aspects. (C) 2014 Elsevier Ltd. All rights reserved.

  • A synergistic effect of albumin and H2O2 accelerates corrosion of Ti6Al4V

    Yu, Fei   Addison, Owen   Davenport, Alison J.  

    Abstract The synergistic effect of albumin and H2O2 on corrosion of titanium alloy Ti6Al4V in physiological saline was investigated with long-term immersion tests and electrochemical methods. It was found that in the presence of both albumin and H2O2, the rate of metal release in immersion tests was far higher than in the presence of either species alone. Electrochemical polarisation curves and potentiostatic tests showed that H2O2 increased both the rates of the anodic and cathodic reactions, whilst albumin significantly decreased the rate of the cathodic reaction and slightly decreased the rate of the anodic reaction. The synergistic effect of albumin and H2O2 during immersion tests was attributed to the effect of adsorption of albumin in lowering the rate of the cathodic reaction and thus lowering the open circuit potential into the active region of titanium where complexation by H2O2 increased the corrosion rate. The corrosion attack was found to be greater in the β-phase of the alloy. The findings suggest that current standard tests in physiological or phosphate-buffered saline may underestimate the rate of corrosion in the peri-implant environment, in which albumin is the predominant protein, and reactive oxygen species such as H2O2 can occur as a result of inflammatory reactions in response to surgery, infection, or implant corrosion products. Statement of significance Corrosion of many biomedical implant materials occurs in the body leading to adverse biological responses. Several components of the environment into which a metal implant is placed including proteins and products of cellular physiology, been shown to modify corrosion resistance. Previously all studies on such components including the common protein albumin and the inflammatory product H2O2 have considered the effects of these species in isolation. For the first time we report a synergistic interaction between albumin and H2O2 significantly accelerating corrosion of Ti6Al4V at physiological pH and temperature. This is attributed to an increased rate of the anodic reaction caused by H2O2 complexation of Ti, suppression of cathodic reaction by albumin adsorption shifting OCP to the active region of Ti6Al4V.

  • A 2.7?GHz Low-Phase-Noise LC-QVCO Using the Gate-Modulated Coupling Technique

    Yu, Fei   Tang, Qiang   Wang, Weizheng   Wu, Honglin  

    In this paper, a 2.7 GHz LC-tank quadrature voltage-controlled oscillator (QVCO) is proposed for achieving low phase noise. The excellent phase noise performance is accomplished by the integration of the gate-modulated quadrature phase coupling technique into a complementary oscillator topology. Simulation results show a wide tuning range from 2.6 to 4.4 GHz, a phase noise of −125 dBc/Hz at an offset of 1 MHz, and a phase-noise figure-of-merit of −184.5 dBc/Hz, while consuming 5.48 mA for the core QVCO from a 1.5 V supply. The proposed QVCO was designed using a 0.18 μm CMOS process.
