Emission of Climate-Relevant Gases in Organic and Conventional Cropping Systems [PDF]
, 2008 In 81 commercial farms in Germany, emissions of the greenhouse gases CO2, CH4 and N2O from crop production have been computed by model-based analyses. The considered influence factors comprise farm structure, mass and energy inputs as well as cultivation

Advanced Materials, EarlyView.A systematic study of a series of porous organic cages with perfluorinated alkyl side‐chains of different lengths is presented. The structure‐property relationship of the various cages on gas sorption of highly potent greenhouse gases, such as perfluorocarbons (PFCs), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3) is investigated.

Artificial Greenhouse Gases as Exoplanet Technosignatures
The Astrophysical JournalAtmospheric pollutants such as chlorofluorocarbons and NO _2 have been proposed as potential remotely detectable atmospheric technosignature gases. Here we investigate the potential for artificial greenhouse gases including CF _4 , C _2 F _6 , C _3 F _8 ,

Atmospheric Pollution and Consumption Patterns in Spain: An Input-Output Approach [PDF]
This paper analyses the relationship between Spanish household consumption patterns and atmospheric pollutant emissions in 2000. Applying an input-output approach we estimate the relative responsibility of different types of households in the emissions ...

Development of Heat Engines Powered by Twisted and Coiled Polymer Fiber Actuators
Advanced Materials Technologies, EarlyView.Continuously rotating engines driven by thermally responsive actuating materials can turn waste heat into useful energy. For the first time heat engines operated by twisted and coiled polymer fiber actuators are demonstrated with engine design guided by two simple analytical models.

Advanced Photonics Research, EarlyView.This study investigates high‐efficiency double perovskite active layer (DPAL) structures using MAPbI3 and MASnI3 to surpass the Shockley‐Queisser limit in single‐junction perovskite solar cells. SCAPS‐1D simulations show that the V2O5‐assisted DPAL device achieves 34.14% power conversion efficiency with improved JSC, VOC, and FF.
