Phosphorus sorption, accumulation and leaching [PDF]

open access: yes, 2003
Arable land is a major diffuse source of P loads to surface waters. The main processes for P losses from agricultural fields are erosion, surface runoff and subsurface leaching.

Separation and Extraction of Rhenium from Waste Acid via Selective Precipitation and Atmospheric Pressure Leaching

open access: yesSeparations
This study presents a combined process of sulfide precipitation followed by hydrogen peroxide leaching for rhenium recovery from copper smelting waste acid under ambient temperature and pressure. The process first removed copper through selective sulfide

Evaluation of the impact of various agricultural practices on nitrate leaching under the root zone of potato and sugar beet using the STICS soil–crop model [PDF]

open access: yes, 2008
The quaternary aquifer of Vitoria-Gasteiz (Basque Country, Northern Spain) is characterised by a shallow water table mainly fed by drainage water, and thus constitutes a vulnerable zone in regards to nitrate pollution. Field studies were performed with a

CO2‐to‐CO Conversion in a Gas‐Fed, Zero‐Gap, PEM Electrolyzer Enabled by Polycations and Nitrogen‐Doped Carbon‐Supported Cobalt Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
A gas‐fed, zero‐gap, PEM CO2 electrolyzer is realized by incorporating PDDA+ ions onto the carbonaceous Co/N‐C electrocatalyst, with gaseous H2 and CO2 fed into the anode and cathode, respectively. Operating without an aqueous electrolyte, the system sustains a peak FECO of 65.1% at 100 mA cm−2. ABSTRACT Electrochemical carbon dioxide reduction (ECO2R)

Contribution of Dissolved Organic Carbon Leaching to the Annual Carbon Budget of a Dairy Farm [PDF]

open access: yes, 2013
Soils are the largest terrestrial store of carbon (C) and changes in this store of C can impact on soil quality and atmospheric CO2 concentrations.

Selective Leaching of Steelmaking Slag for Indirect CO2 Mineral Sequestration

open access: yes, 2010
Indirect CO2 mineral sequestration, which could make CO2 fixate into precipitated calcium carbonate (PCC) of value-added products, is an important technology that is used to reduce greenhouse gas emissions economically.
