Self-cleaning ability and cooling effect of TiO2-containing mortars

Diamanti M.V., Paolini R., Zinzi M., Ormellese M., Fiori M., Pedeferri MP., Politecnico di Milano, IT

This work focuses on the characterization of a self-cleaning and photocatalytic system for building façades, aimed at improving urban surfaces and the surrounding air quality, and decreasing energy consumption. Mortars containing anatase TiO2 nanopowders were [...]

Development of Innovative Packaging Characterized by Active Thermal Insulation Properties

Garbagnoli P., Altomare L., Del Curto B., De Nardo L., Del Curto B., Cigada A., Politecnico di Milano, IT

An innovative composite material based on cellulose matrix has been developed. Active thermal insulation properties have been conferred to the material through the integration of Phase Change Materials (PCM) into the matrix. Processing techniques of [...]

Advanced Membrane Design for Improved Carbon Dioxide Capture

Nwogu N.C., Gobina G., Robert Gordon University,Aberdeen, UK

The new membrane is made of nano-structured materials by means of novel dip-coating techniques to function according to the intention. As a result, with this method, it is possible remove more CO2 and obtain a [...]

Ionic Liquids for CO2 capture

Stiemke F., Iliev B., Adamová G., Schubert T.J.S., Romanos G., Kroon M., IOLITEC Ionic Liquids Technologies Inc., US

Since it is known that IL have the tendency to retain CO2 both physically (physical sorption) as well as chemically (chemisorption)[1], they can be used for the direct capture of CO2 replacing the current process [...]

Polyol–clay matrices with improved hydrophilic character and affinity towards CO2 – Attempts to CO2 concentration at room temperature

Nousir S., Ghomari K., Roy R., Azzouz A., University of Quebec at Montreal, CA

Polyol-clay matrices were prepared by incorporating various polyalcohols ranging from ethylene-glycol to bulky polyol dendrimers. Through thermal programmed desorption (TPD) revealed a significant enhancement of both the hydrophilic character and affinity towards CO2. The amounts [...]

Amine-Containing Nanoporous Materials for CO2 Removal

Sayari A., University of Ottawa, CA

Amine-containing nanoporous materials gained tremendous popularity in recent years as adsorbents for CO2 removal. When properly designed, amine-functionalized materials exhibit high adsorption capacity, fast CO2 adsorption and desorption, and low-energy requirements for recycling compared to [...]

Advanced Materials and Process for CO2 Removal from Flue Gas

Sweeney J., Petruska M., Carruthers D., Hornbostel M., Krishnan G., ATMI Inc., US

ATMI and SRI have developed an entirely new approach to CO2 capture comprising an engineered carbon molecular sieve and an integrated adsorption fractionation process. The carbon has been engineered specifically for this application and acts [...]

Application of Magnetic Nanoparticles for Wastewater Treatment using Response Surface Methodology

Lakshmanan R., Okoli C., Boutonnet M., Järås S., Rajarao G.K., Royal Institute of Technology (KTH), SE

The removal of contaminants in wastewater treatment process is challenging due to complex substances, time and cost involved thus, advance technologies in the treatment process are necessary. The present study investigates the potential of magnetic [...]

Life Cycle Assessment for Assessing Carbon Footprints of Water Supply System in Taiwan

Hu A.H., Huang C-Y, Huang C-Y, Fan C-W., National Taipei University of Technology, TW

This study aims to calculate the carbon footprints of two water supply systems in Taiwan, one is a traditional water treatment plant (FYWTP) and another is a seawater desalination plant (KSDP) and each with different [...]

Sustainability Stations

Guadalupe Morales M., UNAM, MX

The Sustainability Stations is a project focused in solve Mexico City´s problem of lack of water and inundations. Both situations are related to the water extraction from the water table, being the principal source of [...]
