题目：Nanomanufacturing of Polymers and Composites at the University of Massachusetts Lowell，聚合物与复合材料的纳米制备技术

摘要：The goal of research in Nanomanufacturing is understanding the fundamental science of not only how to manipulate structures or features at the nanoscale, but also how to do so in ways that can be scaled up to high rates, high volumes, and large areas, with the reliability needed for commercial products.  Many early manufacturing processes approaching the nanoscale were incremental advances in industrial microelectronics processes – e.g., the ability to push lithography and etching down to finer and finer resolutions.  A different approach is combining the methods used in the plastics industry – extrusion, fiber spinning, molding – with new ways of achieving control at the nanoscale.  Such integrated nano-micro-macro processes, utilizing mechanisms such as chemical, electrical, and rheological responses, enable a completely different range of structures that can be formed.  This presentation will give examples of several nanomanufacturing methods, as well as the results of some research on the fundamental mechanisms affecting repeatability, reliability, and functionality of the fabricated structure.

    In addition to being designated a state-funded Nanomanufacturing Center of Excellence, UMass Lowell is part of a unique equal partnership with Northeastern University and the University of New Hampshire in the National Science Foundation (NSF) sponsored Center for High Rate Nanomanufacturing (CHN).  Funded as part of the NNI, this Center is one of only four NSF Centers in the US that focuses on nanomanufacturing.

题目：Developing Responsible Nanomanufacturing: Challenges and Progress，开发可靠的纳米制造技术：挑战与进步

摘要：Nanotechnology, similar to other emerging technologies, came with the great promises of novel materials, products and breakthrough cures for disease.  New technologies, however, come with the unknown inherent risks of adverse health to humans and the environment.  Past history of technological development serves as a strong reminder that failures to address potential environmental and human health impact of new technologies may threaten their very existence. The fate of genetically modified organism (GMOs), the predecessor to nanotechnologies, where the concerned public rejected the technology, prompted an unprecedented proactive effort by multiple stake holders to develop nanotechnologies responsibly. The Center for high rate nanomanufacturing was among the first to incorporate health and safety aspects of nanotechnologies (exposures, toxicity, and hazard evaluation, as well as intervention research) into its core activities. While progress has been made, the road has been difficult and challenging. This talk will focus on our experiences with and challenges of studying the health and safety aspects of nanotechnologies and discuss alternative models for safe development of emerging technologies.

Dr. Bello completed a post-doctoral training in environmental epidemiology at the Harvard School of Public Health (HSPH) with Prof. Thomas Smith, during which time he specialized in biologically-relevant approaches of exposure assessment for epidemiology. Dr. Bello’s current research includes toxicity screening approaches for and exposure assessment of engineered nanomaterials, development and/or exploration of novel exposure metrics, skin exposure to chemicals, and disease prevention.

Dr. Bello holds a visiting scientist position at the Harvard School of Public Health and is actively collaborating with researchers at HSPS, MIT, and Yale University. He is an editorial board member of the Annals of Occupational Hygiene and has served as a scientific reviewer on several grant applications for the National Institute for Occupational Safety and Health (NIOSH), Department of Defense, and National Institute of Environmental Health Sciences (NIEHS), including the recent NIEHS center grant applications on nanotoxicology. Additionally, he has also served on editorial boards, advisory committees, and review panels for several journals and conferences. Dr. Bello has been an invited speaker, including as keynote speaker, at several conferences and workshops, such as the 2010 workshop on harmonization of exposure assessment efforts for engineered nanomaterials and the 2009 conference on occupational and environmental exposure of skin to chemicals. His teaching responsibilities include evaluation of workplace hazards, nanomaterials: exposures, health and safety, and human exposure assessment.  

Dr. Bello has over 10 years of interdisciplinary educational and research background, with training in analytical chemistry, exposure sciences, and biomarkers. His main thrust of research is exploring the links between real-world human exposures and disease. Examples of his recent work include: investigation of inflammatory cytokines (such as in nasal lavage and cells) as early effect biomarkers for engineered nanomaterials, role of skin in sensitization and asthma, links between physicochemical properties of engineered nanomaterials and biological oxidative damage in human serum, and exploration of novel, biologically-relevant exposure metrics for human epidemiology. Dr. Bello is an active member of the NSF-funded Center for High Rate Nanomanufacturing, and his research focuses on human exposure assessment to nanomaterials and toxicity screening. He believes that major developments and breakthroughs in the exposure sciences and public health research will come from exploration of the interdisciplinary space.

 

                                                          

 题目：Multifunctional Nanomaterials for Nanoelectronics Assembly and Nanosensor Integration,用于纳米电子组装和纳米传感器集成的多功能纳米材料

摘要：We have successfully synthesized various types of lead-free nano-solders in the form of spherical particles, nanorods, and high aspect ratio nanowires. The main focus of this presentation will be the assembly and joint formation of multisegmented nanowires using lead-free nano-solders. We have used electrodeposition method to synthesize multisegmented nanowires in nanoporous templates, in the diameter range of 15-200 nm and length up 20 µm. Nano-solders have been directly fabricated onto nanowires and are then used for soldering nanowires with functional joints. Self-assembly method, such as magnetic assembly or dielectrophoretic (DEP) assembly, has been developed to integrate nanowires into large-scale 2D or 3D network structures with conductive solder joints. These nanowires and nano-soldering techniques have great potential for the assembly and integration of functional nanoelectronics and nanosensors.
