Low Temperature Activation of CO Removal by O3-Assisted Catalysis

21.11.2014 | Sungkwon Jo; Kwan-Tae Kim; Dae Hoon Lee; Young-Hoon Song; Jae-Ok Lee; Taewoo Lee; Hyun-Sik Han, Environmental Science & Technology, 2014

Catalytic CO oxidation was activated at low temperature by injecting O3 as an additive. It was empirically confirmed that CO removal rate was dramatically enhanced by supplying a small amount of O3, and the reaction temperature was almost half that required for CO oxidation when using a catalyst ...

Full-Scale Validation of a Model of Algal Productivity

20.11.2014 | Quentin Béchet; Andy Shilton; Benoit Guieysse, Environmental Science & Technology, 2014

While modeling algal productivity outdoors is crucial to assess the economic and environmental performance of full-scale cultivation, most of the models hitherto developed for this purpose have not been validated under fully relevant conditions, especially with regard to temperature variations. ...

Sustainability, Vol. 6, Pages 8297-8309: A Dual Function Energy Store

20.11.2014 | Tolmie, Ron ; Rosen, Marc A., Sustainability, 2014

Heat can be collected from local energy sources and concentrated into a relatively small volume, and at a useful working temperature, by using a heat pump as the concentrator. That heat can be stored and utilized at a later date for applications like space heating. The process is doing two things ...

High-Yield Harvest of Nanofibers/Mesoporous Carbon Composite by Pyrolysis of Waste Biomass and Its Application for High Durability Electrochemical Energy Storage

17.11.2014 | Wu-Jun Liu; Ke Tian; Yan-Rong He; Hong Jiang; Han-Qing Yu, Environmental Science & Technology, 2014

Disposal and recycling of the large scale biomass waste is of great concern. Themochemically converting the waste biomass to functional carbon nanomaterials and bio-oil is an environmentally friendly apporach by reducing greenhouse gas emissions and air pollution caused by open burning. In this ...

IJERPH, Vol. 11, Pages 11627-11644: Association of Weekly Suicide Rates with Temperature Anomalies in Two Different Climate Types

13.11.2014 | Dixon, P. Grady; Sinyor, Mark ; Schaffer, Ayal ; Levitt, Anthony ; Haney, Christa R.; Ellis, Kelsey N.; Sheridan, Sc ..., International Journal of Environmental Research and Public Health, 2014

Annual suicide deaths outnumber the total deaths from homicide and war combined. Suicide is a complex behavioral endpoint, and a simple cause-and-effect model seems highly unlikely, but relationships with weather could yield important insight into the biopsychosocial mechanisms involved in ...

Number and Size Distribution of Airborne Nanoparticles during Summertime in Kuwait: First Observations from the Middle East

13.11.2014 | Abdullah N. Al-Dabbous; Prashant Kumar, Environmental Science & Technology, 2014

We made fast response measurements of size-resolved particle number concentrations (PNCs) and distributions (PNDs) in the 5–1000 nm range close to a busy roadside, continuously for 31 days, in Kuwait. The aims were to understand their dispersion characteristics during summertime and dust events, ...

IJERPH, Vol. 11, Pages 11616-11626: Influence of Daily Individual Meteorological Parameters on the Incidence of Acute Coronary Syndrome

12.11.2014 | Ravljen, Mirjam ; Bilban, Marjan ; Kajfež-Bogataj, Lučka ; Hovelja, Tomaž ; Vavpotič, Damjan, International Journal of Environmental Research and Public Health, 2014

Background: A nationwide study was conducted to explore the short term association between daily individual meteorological parameters and the incidence of acute coronary syndrome (ACS) treated with coronary emergency catheter interventions in the Republic of Slovenia, a south-central European ...

IJERPH, Vol. 11, Pages 11481-11504: Modeling Spatial and Temporal Variability of Residential Air Exchange Rates for the Near-Road Exposures and Effects of Urban Air Pollutants Study (NEXUS)

07.11.2014 | Breen, Michael S.; Burke, Janet M.; Batterman, Stuart A.; Vette, Alan F.; Godwin, Christopher ; Croghan, Carry W.; S ..., International Journal of Environmental Research and Public Health, 2014

Air pollution health studies often use outdoor concentrations as exposure surrogates. Failure to account for variability of residential infiltration of outdoor pollutants can induce exposure errors and lead to bias and incorrect confidence intervals in health effect estimates. The residential air ...

IJERPH, Vol. 11, Pages 11421-11437: Multivariate Optimization for Extraction of Pyrethroids in Milk and Validation for GC-ECD and CG-MS/MS Analysis

05.11.2014 | Meneghini, Leonardo Zanchetti; Rübensam, Gabriel ; Bica, Vinicius Claudino; Ceccon, Amanda ; Barreto, Fabiano ; Ferr ..., International Journal of Environmental Research and Public Health, 2014

A simple and inexpensive method based on solvent extraction followed by low temperature clean-up was applied for determination of seven pyrethroids residues in bovine raw milk using gas chromatography coupled to tandem mass spectrometry (GC-MS/MS) and gas chromatography with electron-capture ...

Biofouling and Microbial Communities in Membrane Distillation and Reverse Osmosis

31.10.2014 | Katherine R. Zodrow; Edo Bar-Zeev; Michael J. Giannetto; Menachem Elimelech, Environmental Science & Technology, 2014

Membrane distillation (MD) is an emerging desalination technology that uses low-grade heat to drive water vapor across a microporous hydrophobic membrane. Currently, little is known about the biofilms that grow on MD membranes. In this study, we use estuarine water collected from Long Island ...
