Gold nanoclusters for air purification applications

Mendoza E., Goldemar Solutions, US

Nowadays, public concern and the enforcement of environmental regulations by governments have made it necessary to develop versatile materials capable of efficiently eliminating a wide range of organic pollutants from both indoor and outdoor emissions. [...]

A Clean and Green Route for the production of methacrylic acid and methacrolein from biofuel

Lin M.M., Grinberg J., Eng W., EverNu Technology, LLC, US

The modern consumption of fossil fuels for chemical production contributes to global warming and other nature disasters in recent years. Approximately 10% of U.S. crude oil imports are used to feed its chemical industry. There [...]

3D printing: How emerging materials, applications, and business models will disrupt manufacturing and enhance future innovation

Vicari A.C., Lux Research, US

From personalized medicine to personal drones, 3D printing – the additive manufacturing of objects by depositing and patterning successive layers of material – has been touted as an enabling platform for many compelling applications. Among [...]

$/W Costs of Thermoelectric Waste-Heat Recovery for Stationary Applications

LeBlanc S., Yee S.K., Scullin M., George Washington University, US

Interest in thermoelectrics for waste-heat recovery has flourished in recent years, but questions about cost and scalability remain unanswered. Prior work investigated the materials, manufacturing, and system costs and thermal and electrical transport factors that [...]

STEP, Efficient solar syntheses: A comprehensive approach to decreasing the concentration of atmospheric carbon dioxide

Lau J., Licht S., Stuart J., Li F-F, Licht S., Meng F., George Washington University, US

The Solar Thermal Electrochemical Process (STEP) was introduced to provide a complete solution to lowering carbon dioxide in the atmosphere (1). STEP utilizes a synergy of thermal and electrochemical energy to drive endothermic processes at [...]

Applications of Enzymatic Saccharification Residues as a Fully Biobased Adhesive

Hafez I.H., Yang H., Tze W.T.Y., University of Minnesota, US

When woody biomass is enzymatically treated to release from its polysaccharide components fermentable sugars for bio-alcohols and other chemicals production, it typically leaves behind in the waste stream solid residues that are rich in lignin. [...]

Electrospun Nanocomposite Nerve Guidance Conduits for Peripheral Neural Regeneration

Zhu W., Zhang L., The George Washington University, US

A novel tissue engineered scaffold was fabricated by electrospinning and electrospraying techniques, which possesses highly aligned poly-ε-caprolactone (PCL) microfibrous framework and adjustable neurotropic factor embedded poly (D, L-lactide-co-glycolide) (PLGA) nanospheres. Scanning electron microscope revealed the [...]

Polymer Based Continuous Offset Printing

Mead J., Barry C., University of Massachusetts-Lowell, US

Polymeric materials have tremendous potential for nano and micro-structured products because of their fabrication ease and wide property range. The fabrication processes for polymers are cost-effective and rapid. This work presents novel manufacturing approaches for [...]

Advancements in Microelectronics-Grade Carbon Nanotube Materials for NRAM® Device Manufacture and Analysis of Carbon Nanotube Mass in End User Devices

Lamb J.E., Gibbons S., Trichur R., Jiang Y., Mangelson K., Kremer K., Janzen D., Brewer Science, Inc, US

Providing materials for use in semiconductor manufacturing is challenging due to the extreme quality levels required for low metal ion and defect levels. This challenge is much greater for suppliers of materials containing long, high-aspect-ratio [...]

High-rate Manufacturing of 3D Products with Micro and Nanostructured Surfaces

Barry C., Mead J., University of Massachusetts-Lowell, US

Injection molding permits the manufacturing of complex three-dimensional products with micro and nanostructured surfaces in less than 30 seconds. Successful high-rate manufacturing of these surfaces depends on understanding the changes required in material selection, tool [...]
