Green chemistry is a systematic scientific and engineering approach that seeks to reduce the use of hazardous chemicals and the generation of toxic wastes by changing how society designs, manufactures, and uses chemicals in processes and products. Rather than managing wastes after end-of-product life, green chemistry shifts our focus to designing chemicals, processes, and goods that have less or no...
The structure of university-industry collaboration networks for developing lead-free solders is analyzed with the quantitative methods of social network analysis, based on data on the participants in research and development projects. Initiatives to regulate the use of lead in the United States influenced the formation of university-industry collaboration network for the development and adoption of...
This work uses hybrid life cycle assessment methods to determine the overall energy use of a commercial LED lamp. Life cycle inventory (LCI) data is built up using industry data for a GaN-based white LED lamp designed to replace conventional incandescent bulbs. Appropriate data are also taken from generic processes in the semiconductor manufacturing sector. By considering the entire life cycle of...
