Remote sensing of water quality in the Rotorua lakes [PDF]

open access: yes, 2007
The aim of this study was to determine empirical models between Landsat imagery and lake water quality variables (chlorophy11(ch1) a and Secchi depth) to enable water quality variables to be synoptically quantified. These models were then applied to past

Extrinsic and Intrinsic Charge Transfer at Interfaces of Membrane‐Based Oxide Heterostructures

open access: yesAdvanced Electronic Materials, EarlyView.
Freestanding oxides have emerged as a new opportunity to tailor oxides outside of the typical epitaxial constraints. We present the fabrication of TiO2‐terminated SrTiO3 membranes via direct growth control. We demonstrate competing ionic and electronic charge transfer in LaAlO3/SrTiO3 bilayers using near ambient pressure XPS.

Disproportionate Environmental Risks: A Descriptive Analysis of Chemical Facilities and Accidents in the United States

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Using nationwide data on the US Environmental Protection Agency's Risk Management Plan (RMP) program, we examine the proportions of underserved populations living near facilities that use extremely hazardous chemicals, both before and after accidents involving fires, explosions, and/or toxic vapors occur.

Is Precision Agriculture Technology Adoption Persistently Overestimated?

open access: yesAgribusiness, EarlyView.
ABSTRACT Precision agriculture is sometimes assumed to diffuse steadily over time, and industry planning frequently extrapolates early adoption trends forward. This study evaluates the accuracy of such expectations by comparing agricultural input dealers' forecasts of future service offerings with the actual levels of offerings that dealerships ...

Supramolecular Enforcement of Planar Tetracoordinate Halides

open access: yesAngewandte Chemie, EarlyView.
A calix[4]pyrrolato‐indium scaffold preorganizes Li4 pockets that trap Cl−, Br−, and I− in strongly flattened to square‐planar tetracoordinate environments. Computations reveal low planarization energies for the heavier halides, while crystallography shows that their geometry is readily modulated by subtle supramolecular and packing effects ...
