Industrial Symbiosis Using Green Chemistry
The twin problems of resource depletion and growing amounts of waste can be solved through the valorization of waste into chemical, fuel and material products. While future “closed-loop” manufacturing should reduce waste through in-house use [...]
Polymer Matrix Nanocomposites via Forest Derived Nanomaterials
Trees are a likely source of bioderived nanomaterials for polymer matrix composites (PMCs). All trees and plants utilize a nanoscale fiber as a building block in their reinforcing phase. The presence of nanofiber in cell [...]
Improving the End-of-Life for Electronic Materials via Sustainable Recycling Methods
The production of electronic equipment such as computers, cell phones, TVs, etc. is one of the fastest growing global manufacturing activities. Unfortunately this results in substantial quantities of waste electric and electronic equipment (WEEE). In [...]
Nano-enabled Green Technologies for Electronics and Energy Applications
Green electronics is largely driven by performance limitations of scaled Si-based CMOS due to the exceptionally high power dissipation arising in such devices at nanoscale dimensions. Novel architectures for computation are currently in consideration, which [...]
Screening Level Cradle to Grave Life Cycle Assessment of a Conceptual Carbon Nanotube Field Emission Display Device
The case study focuses on performing a screening level Life Cycle Assessment (LCA) of a hypothetical 15-inch CNT-FED device. The life cycle inventory (LCI) for the manufacture of the CNT-FED is based on values from [...]
The Effect of Lamination on Printed Silver Tracks for Plastic Circuits
To combat the global e-waste crisis, there is an urgent need to develop a technology where environmental pollution from electronics, their manufacturing and product end of life is minimized through recycling and re-use. Circuits in [...]
Self-assemblies of magnetic nanoparticles (MNPs) and peroxidase enzymes: mesoporous structures and nanoscale magnetic field effects (nano-MFEs) for enhanced activity BioNanoCatalysts (BNCs)
BNCs are self-assembled complexes of magnetic nanoparticles and free-radical producing enzymes, including peroxidases and other oxido-reductases that were shown to have higher activities than their free-enzyme counterparts (up to 30 folds). The BNCs biochemical properties [...]
Novel Green Polymer Composites: Major Enhancements in the Crystallization Kinetics of Poly(lactic acid) and Mechanical Properties of Polypropylene Created via Solid-State Shear Pulverization
Hybrids of polylactide (PLA) or polypropylene (PP) with microcrystalline cellulose (MCC) were created using a continuous, industrially scalable, and environmentally benign process called solid-state shear pulverization (SSSP). The PLA composite was subsequently melt-processed (MP) with [...]
Computational Studies on Mechanisms for the Organocatalytic Depolymerization of Poly(ethylene) Terephthalate
Jones G.O., Horn H.W., Wei D.S., Fukushima K., Lecuyer J.M., Coady D.J., Hedrick J.L., Rice J.E., IBM, US
Poly(ethylene) terephthalate (PET) is a widely used thermoplastic commonly found in packaging products and that constitutes a large percentage of total plastic refuse. We have examined the depolymerization of PET with alcohols and amines, a [...]
Ageing of elastomeric composites with natural antioxidants
The natural antioxidants which were added to ethylene-octene elastomer (polyolefin elastomer-Engage). Vulcanizates were then subjected to numerous ageing: weathering (climat of Floryda), UV (0,7 W/m2), thermo-oxidation ageing (1000C/10days) and thermal-shock (-600C/+1000C) as a function of [...]
Reducing Material Waste in Biodiesel Production through Multi-Energy Optimized Processing
Multi-Energy Optimized Processing is a patented green chemical processing technique which substitutes focused energy for hazardous chemicals to achieve efficient fuel conversions. Applied to bio diesel production, this technology reduces material waste in the form [...]
Metal-doped Photocatalysts to Reduce Carbon Dioxide in Ethanolamine Solution for Methane Production
Photocatalytic reduction of carbon dioxide (CO2) to form valuable energy source of methane in the ethanolamine (MEA) solution is investigated in this study. The TiO2 photocatalysts were prepared by doping with nano-sized metals (Fe, Zn, [...]
