Nitrogen leaching from effluent irrigated pasture
, 2011 The surface waters of the Taupo region are of high quality and are sensitive to inputs of nitrogen. To reduce the amount of nitrogen discharged to surface water, the Taupo District Council (TDC) has employed a land treatment scheme (LTS), where treated ...

Comparison on the leaching kinetics of chalcocite and pyrite with or without bacteria
, 2010 The acid leaching, ferric leaching, and bioleaching of chalcocite and pyrite minerals were conducted in two sets of 3L stirred reactors The dissolution rates of copper and iron were correlated with leaching conditions In the acid leaching process, the ...

Toward Fast Proton Shuttling in Acidic Oxygen Evolution Reaction
Advanced Functional Materials, EarlyView.This review establishes proton transfer dynamics as a descriptor governing acidic OER activity, moving beyond the kinetic constraints derived from the proton coupled electron transfer. We discuss how deprotonation governs classical mechanisms, including adsorbate evolution mechanism (AEM), lattice oxygen mechanism (LOM) and oxide path mechanism (OPM ...

Conformal Metallosaccharide Hybrid Films for Protecting Wood Surfaces From Environmental Damage
Advanced Functional Materials, EarlyView.Ti‐ribose hybrid films fabricated by molecular layer deposition form a conformal and uniform coating on wood surfaces, which provides water repellence, dimensional stability, and resistance to acidic and alkaline environments, while preserving the natural appearance.

An Electrochemical Study of the Oxidative Dissolution of Synthetic Nickel-Iron Sulphide Minerals in Aqueous Media [PDF]
, 1988 Pentlandite (Fe4.5Ni4.5S8) and violarite (FeNi2S4) were synthesized by dry in vacuo techniques. The products were analysed by reflected light microscopy, powder X-ray diffraction and electron microprobe analysis.

Advanced Healthcare Materials, EarlyView.A long‐lived, five‐cell‐type human neurovascular (PENTA) model recreates vascular disorganization and incomplete repair after traumatic brain injury (TBI). By integrating endothelial, glial, neuronal, and immune components within a 3D scaffold, the platform enables time‐resolved analysis of neurovascular remodeling and provides a human‐relevant system ...

Leaching kinetics of szaibelyite ore in NaOH solution
, 2015 The leaching of szaibelyite ore in NaOH solution to prepare sodium metaborate dihydrate was investigated in a batch reactor. The effects of the reaction temperature, NaOH concentration and liquid to solid ratio on the leaching rate have been evaluated ...
