Monitoring of nitrogen leaching on a dairy farm during four drainage seasons [PDF]

open access: yes, 2006
peer-reviewedThe authors acknowledge funding from the Environmental Protection Agency and Teagasc under the 2000–2006 RTDI programme.The effect of four commonly used dairy farm management systems (treatments), on nitrogen leaching to 1 m was studied over

Mechanism of Vanadium Leaching during Surface Weathering of Basic Oxygen Furnace Steel Slag Blocks: A Microfocus X-ray Absorption Spectroscopy and Electron Microscopy Study [PDF]

open access: yes, 2017
© 2017 American Chemical Society. Basic oxygen furnace (BOF) steelmaking slag is enriched in potentially toxic V which may become mobilized in high pH leachate during weathering.

Comparing soil carbon loss through respiration and leaching under extreme precipitation events in arid and semiarid grasslands [PDF]

open access: yesBiogeosciences, 2018
Respiration and leaching are two main processes responsible for soil carbon loss. While the former has received considerable research attention, studies examining leaching processes are limited, especially in semiarid grasslands due to low ...

Oxygen and ROS Delivery for Infected Wound Healing and Future Prospects

open access: yesAdvanced Healthcare Materials, EarlyView.
Bacterial infection is a major driver of delayed wound healing and postsurgical readmissions; with rising antibiotic resistance, solid peroxide–releasing biomaterials offer sustained delivery of ROS/O2 for antimicrobial control and microenvironmental modulation.

Aeolianite and barrier dune construction spanning the last two glacial-interglacial cycles from the southern Cape coast, South Africa [PDF]

open access: yes, 2004
The southern Cape region of South Africa has extensive coastal aeolianites and barrier dunes. Whilst previously reported, limited knowledge of their age has precluded an understanding of their relationship with the climatic and sea-level fluctuations ...

Flexible Polypyrrole‐Based pH Sensors via Oxidative Chemical Vapor Deposition

open access: yesAdvanced Healthcare Materials, EarlyView.
Oxidative chemical vapor deposition (oCVD) of polypyrrole (PPy) thin films yields flexible, electrically conductive, and biocompatible pH sensors for monitoring on‐skin biological events. The highly sensitive, oCVD PPy skin‐conformal sensors enable real‐time, spatially resolved sensing of dynamic pH changes within physiologically relevant ranges (4–9 ...

The alkaline sodium sulphide leaching of enargite

open access: yes, 2011
Leaching of enargite samples containing approximately 12 % As, 0.5 % Sb and 38 % Cu was studied in alkaline sodium sulphide solutions. Samples were leached in the presence of sodium hydroxide and sodium sulphide, which is expected to hydrolyse and form sodium hydrosulphide.

Alkaline Leaching: A Facile Surface Activation Strategy to Improve the Reactivity of Air Electrodes for Solid Oxide Fuel Cells

open access: yesAdvanced Materials, EarlyView.
This study shows that alkaline leaching of PrBa0.8Ca0.2Co2O5+δ under anodic bias selectively removes Ba and Ca, forming a cobalt‐rich and amorphous layer. The modified surface significantly boosts ORR activity, offering a simple and effective strategy to improve electrochemical device performance.

Resource recovery and remediation of highly alkaline residues : a political-industrial ecology approach to building a circular economy [PDF]

open access: yes, 2017
Highly alkaline industrial residues (e.g., steel slag, bauxite processing residue (red mud) and ash from coal combustion) have been identified as stocks of potentially valuable metals.
