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, [...]
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 [...]
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 [...]
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 [...]
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 [...]
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 [...]
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 [...]
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 [...]
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 [...]
