Improving the optical-radiative properties of TiO2 containing coatings – a side effect of air purification

Paolini R., Sleiman M., Pedeferri M.P., Diamanti M.V., Politecnico di Milano, IT

A manifold positive contribution to climate change mitigation and in the improvement of air quality of built environments can be provided by the use of titanium dioxide (TiO2), also – but not exclusively – as [...]

Kinetic and thermodynamic investigation of CO2 adsorption-desorption on polyethyleneimine – mesoporous silica

Khader M.M., Al-Marri M.J., Kuti Y.O., Giannelis E.P., Qatar University, QA

This study combines measurements of the kinetics and thermodynamics of carbon dioxide adsorption-desorption on polyethylene mesoporous silica (PEI/MPS) in the temperature range from 45 to 85℃. The study was performed on two CO2 solid sorbents: [...]

Process Development and Pilot Demonstration of Cabon Capture Coupled Co-Production of Calcium Carbonate and Ammonium Sulfate

Zhu J., Xia S., Li J., Gong Y., Zhou J., Sichuan University, CN

Summary Carbon capture and storage (CCS) was affirmed to be a major component of a cost-effective portfolio of emission reduction strategies, by 2030 and beyond. However, there are still no full-scale applications on a commercial [...]

Multiscale Modeling and Experimental Study of CO2 Absorption into Ionic Liquid Reverse Micelle

Shi W., Hong L., Kusuma V.A., Hopkinson D.P., National Energy Technology Laboratory, US

Highly viscous solvents for gas absorption will lead to large pumping power requirement and large absorption/desorption tower, resulting in high capital cost. Ionic liquids (ILs) represent such examples even though ILs have been extensively studied [...]

Ruthenium Nanoparticles Media with in Ionic Liquid in Carbon Dioxide Valorisation to Methane

Bogel-Łukasik E., LAQV/Universidade Nova de Lisboa, PT

Carbon dioxide (CO2) is a very stable molecule and hydrogen reduction of CO2 to produce CO, the reverse water-gas shift reaction, only becomes thermodynamically favourable at temperatures higher than 1110K. CO2 emissions resulting from the [...]

An integral approach for water treatment and the use of water-energy interdependency network

Lin Y., Zhou Z., Pan S-Y, Snyder S., Argonne National Laboratory, US

Freshwater stress and scarcity is one of the most challenging emerging issues due to climate change, rapid population growth, urbanization, and improved standards of living. Desalination of seawater or impaired water, such as brackish water [...]

Controlled Release Polymers for Remediation of Contaminated Groundwater

Carpenter A., Gause C., Luster-Teasley S., AxNano, US

The EPA estimates that one out of every four Americans lives within three miles of a hazardous waste site. Over 450,000 brownfield sites are awaiting remediation with 1,280 sites on the National Priorities List (NPL). [...]

Adsorption of paracetamol onto carbon nanomaterials and degradation by ultrasonic and gamma radiation

Hernández-Martínez A., Valdés-Callado M., González-Labrada Katia, Rapado-Paneque M., Chávez-Ardanza A., Arias M., Serp P., Bacsa R.R., Jáuregui-Haza U.J., University of Artemisa, CU

The processes integration does the treatment of wastewater polluted with pharmaceuticals a more efficient process. The adsorption of pollutants on different material, like carbon based or silica is one of the technologies more studied for [...]

GO-based filtration membrane for removal of Endocrine Disrupting Compounds (EDCs) from water

Paneri A., Moghaddam S., University of Florida, US

We live in a world where synthetic chemicals have become a part of our day-to-day life. As a result, some of these pollutants enter our water streams and food chain and interfere with the normal [...]
