The information about the Keynote Speakers of CHEMBIO2018 are as follows, which will be updated regularly.

Dr. Zhang Li, Professor
College of Environment and Energy Engineering, Beijing University of Technology, China

Biography: Dr. Zhang Li obtained her doctor degree in Kumamoto University, Japan in 2011. Since 2015, she had been an associate professor in Chinese Research Academy of Environmental Sciences. In 2017, she transferred to Beijing University of Technology and became a professor and a master supervisor. In recent 5 years, based on the National major scientific research plans such as "Major Science and Technology Program for Water Pollution Control and Treatment, National Key Technology Support Program, National Natural Science Funds Fund" and so on, composed of 3 research assistants and 10 graduate students, her research team focused on investigating high-rate nitrogen removal by Anaerobic ammonia oxidation (Anammox) process. They utilized combined techniques (spectroscopy, mass spectrometry, molecular biology and so on) to elucidate the distribution characteristics of microbial communities under different environmental conditions, and reveal their role in the process of nitrogen migration and transformation. She was awarded Second prize of Environmental Protection Technology Award (ranked eighth) in 2015; First prize of the excellent paper in academic annual meeting of Chinese Society For Environmental Sciences in 2015; "Outstanding young scholar" certificate issued by Japanese Society of Biology in 2012; Second prize of Environmental Protection Technology Award (ranked fifth) in 2018. She published nearly 50 research papers, among which nearly 40 papers belong to SCI. 8 item patent was authorized. And also 5 monographs were published. She also work as a peer reviewer of some journals, including Journal of Bioscience and Bioengineering, Bioresource Technology, Estuarine, Coastal and Shelf Science, Ecological Engineering, Science of the Total Environment and so on.

Topic: Using Combined Multiple Techniques to Characterize Refractory Organics during Anammox Process

Abstract: Refractory organics contained in the wastewater (such as coal chemical wastewater, landfill leachate) are toxic and difficult to be biodegraded. The need for an effective and efficient process to treat the wastewater is certainly warranted prior to discharge into natural resources. This study applied combined spectroscopy techniques to assess refractory DOM (rDOM) compositional characteristic and investigated its transformation mechanisms during the treatment of mature landfill leachate and coal chemical wastewater by anammox process. With respect to mature landfill leachate, a stable, high nitrogen removal rate of 5.95 kg N/m3/day and a rDOM conversion efficiency of 51% were achieved in anammox reactor (AR). Additionally, the initial rDOM removal was closely related to sludge adsorption, with the adsorption force mainly originating from electrostatic interaction and hydrophobicity. As the operating time increased, the removal mechanism of rDOM in the AR changed from adsorption to adsorption-biodegradation and finally stabilized. Furthermore, Anaerolineaceae, associated with the hydrophobic reaction, were the primary degraders for the rDOM and Candidatus Kuenenia dominated the nitrogen consumption. As far as to coal chemical wastewater, it showed anammox process was effective to degrade refractory organic substances, with the removal efficiency towards fulvic-like, UV-humic acid and Vis-humic acid components of 43.61%, 53.93% and 100%, respectively. Besides, EEM fluorescence spectroscopy was proved to be effective method for assessing dissolved organic nitrogen removal during the anammox treatment process towards mature coal chemical wastewater in this study. Furthermore, a remarkable accumulation (9.3–16.2%) of Ca.Kuenenia occurred in the anammox granules under long-term cultivation in mature coal chemical wastewater, which was functional for the high rate nitrogen removal.

Dr. Tahir Mehmood
The State Key Laboratory of Refractories and Metallurgy, Hubei Province Key Laboratory of Systems Science in Metallurgical Process, International Research Institute for Steel Technology, Wuhan University of Science and Technology, China

Biography: Dr. Tahir Mehmood is a post-doctoral researcher at the State Key Laboratory of Refractories and Metallurgy, Hubei Province Key Laboratory of Systems Science in Metallurgical Process, International Research Institute for Steel Technology, Wuhan University of Science and Technology, Wuhan, P. R. China. Prior to his current status, he was invited by chinese scholerships council (CSC) for Ph.D in materials Science at Huazhong Normal University, Wuhan. His research specialized in Synthesis, Characterizations and functional Properties of Transition Metal and alloy nanostructures and explores the different facile methods to prepare optical and magnetic nanostructures of transition metal oxides, ferrites and binary alloys with controlled size, shape, composition and investigation of structural, optical and magnetic properties by considering the nanoscale effect. He has published more than 20 papers in reputed peer-reviewd journals, and has been participated in several international events on nanoscience and nanotechnology (e.g, World Congress on Chemistry and Chemical Engineering (WCCCE2016) held at Jinan, China during Oct. 23-24, 2016 http://www.wccce.org/2016/keynotespeakers2, and International Conference on Applied Mechanics, Mechanical and Materials Engineering (AMMME2016) http://www.ammme2016.org/keynote.htm, which is to be held on December 18-19, 2016, Xiamen, China). He has completed several independent research project in past. Earlier, He has completed his master degree from Hazara University, Pakistan.

Topic: Synthesis of Single Metal and Metal Alloy Nanowires via Electrochemical Deposition

Abstract: To understand the growth mechanism of electrodeposited Fe, Ni, Ag and Co, we have studied the metal nanowire growth by SEM and Potentiostat by X-ray diffraction (XRD), transmission electron microscope (TEM) and scanning electron microscope (SEM). In an electrolyte the mass transfer of ions takes place by three principal mechanisms: a) Diffusion, b) Migration, and c) Convection. The formation of fcc crystals can be attributed to smaller critical clusters formed at a higher potential, lower deposition temperature and higher concentration of metal ions during electrochemical deposition process. The content of Fe inside nanowires increases with increasing potential, decreasing deposition temperature and increasing concentration of Fe ions. This can be verified by the polarization curves of depositing Fe, Ni, Ag and Co nanowires. Thermal agitation at low temperature is marginal for activating the surface diffusion and the growth is difficult. Using the electrons tunneling theory, we have argued that the current density of the metals depends on the workfunction and width of double layer. The current density increases with decreasing thelength of double layer.
