Photocatalytic Performance of Ag modified and doped TiO2 nanoparticles

Cho C-P, Chang L.-H., National Chi-Nan University, TW

In this work, TBOT was used as the titanium source for preparation of TiO2 nanoparticles, followed by calcination at 500°C for 2 hours to achieve fine TiO2 nanoparticles powder (S1). The obtained S1 powder was [...]

Electrospinning of decorated nanofibers with active cerium oxide nanoparticles

Shehata N., Hassounah I., Meehan K., Camelio J., Virginia Tech, US

Cerium oxide nanoparticles (ceria NPs) attract a great research and commercial interests due to its observable capability to capture radicals and dissolved oxygen molecules. Keeping ceria NPs in active form; containing Ce+3 ions with O-vacancies, [...]

Recovery of phosphate from surface waters using a calcium silicate composite material for potential application in environmental remediation

Cairns M.J., Krauss C., Johnston J.H., Victoria University of Wellington, NZ

In many locations, contamination of surface waters by phosphate due to agricultural run-off is becoming a major environmental concern. Currently, there are no effective means for its removal, due to the low phosphate concentration (< [...]

Life cycle considerations for engineered nanomaterials: A case study for nano-enabled coatings on drywall

Sayes C.M., Rothrock G.D., Norton C.A., West C.S., RTI International, US

Engineered nanomaterials are being incorporated into elements of the building industry. Advantages such as increased resistance to ultraviolet damage, wear and fouling of construction materials are relevant to coatings. Particles engineered at the nanometer size [...]

Using Proton Exchange Membranes (PEMs) to Revolutionize Refrigeration

Bahar B., Xergy Inc, US

Xergy utilizes proprietary technology to create the most efficient and greenest compressor system for refrigeration applications. Kuel-Cell(TM) technology has it’s roots in fuel cell technology and biomimicry and utilizes the greenest possible refrigerant, water. With [...]

High Efficiency Nanofiber Reflectors for Lighting Applications

Lynn Davis J., RTI International, US

Nanofibers are an advanced optical media that can deliver extremely high reflectance values over large areas. The materials are made in high volumes in a roll-to-roll process using known spinning technologies. Nanofiber reflectors are particularly [...]

Technology Prioritization: Transforming the U.S. Building Stock to Embrace Energy Efficiency

Abdelaziz O., Abramson A., Phelan P., U.S. Department of Energy, US

The U.S. Buildings sector is responsible for about 40% of the national energy expenditures. This is mainly due to wasteful use of resources and practices lacking energy efficiency consideration. This paper discusses the role of [...]

Life Cycle Assessment of a Nano TiO2 Coating Self-Cleaning Float Glass

Pini M., University of Modena and Reggio Emilia, IT

Ecodesign of nanoTiO2 self-cleaning float glasses with the LCA (life Cycle Assessment) methodology.

Minimize Thermal Edge Losses with Stainless Steel Envelopes for Vacuum Insulation Panels (VIPs)

Feinerman A.D., Gupta P., Foster C., Yarbrough D.W., Kosny J., Thermal Conservation Technologies, US

Traditional Vacuum Insulation Panels (VIPs) have either a polymer/aluminum film or metallized polymer film exterior. In either case the VIPs are too fragile to be directly attached to a building’s envelope without a superstructure. The [...]

Evaluation of PCM-cardboard composite materials in dynamic thermal conditions

Musitelli M., Garbagnoli P., Diamanti M.V., Del Curto B., Pedeferri M., Politecnico di Milano, IT

In recent years, the use of smart materials to resolve environmental problems in building applications has been increasingly widespread. In particular, Phase Change Materials (PCMs) are used to improve thermal performance of air conditioning system [...]
