Analysis of the Fe 2p XPS for hematite 𝛂 Fe2O3: Consequences of covalent bonding and orbital splittings on multiplet splittings (open access)

Analysis of the Fe 2p XPS for hematite 𝛂 Fe2O3: Consequences of covalent bonding and orbital splittings on multiplet splittings

Article analyzes the origins of the complex Fe 2p X-Ray Photoelectron Spectra (XPS) of hematite (α-Fe₂O₃) and is related to the character of the bonding in this compound. This analysis provides a new and novel view of the reasons for XPS binding energies (BEs) and BE shifts, which deepens the current understanding and interpretation of the physical and chemical significance of the XPS. This article is part of the JCP Special Topic on Oxide Chemistry and Catalysis.

Prioritizing riparian corridors for ecosystem restoration in urbanizing watersheds (open access)

Prioritizing riparian corridors for ecosystem restoration in urbanizing watersheds

This article explores restoration, rather than protection, being the basis for developing a watershed level strategy for improving water quality in urbanizing watersheds.This study uses a geographical information system (GIS) approach that utilizes riparian characteristics extracted from 40-meter wide corridors centered on streams and rivers. The model was applied to 90 sub-watersheds in the watershed of an important drinking water reservoir in north central Texas, USA.

Sub-Antarctic Freshwater Invertebrate Thermal Tolerances: An Assessment of Critical Thermal Limits and Behavioral Responses (open access)

Sub-Antarctic Freshwater Invertebrate Thermal Tolerances: An Assessment of Critical Thermal Limits and Behavioral Responses

Describes study which assessed the upper (CTmax) and lower (CTmin) thermal limits of three freshwater macroinvertebrate taxa with restricted low elevation distribution (20 m a.s.l.) and three taxa restricted to upper elevations (480 and 700 m a.s.l.) in the Magellanic sub-Antarctic ecoregion of southern Chile, and argues that their low tolerance to temperature increase can make them useful as indicators of thermal alteration in their habitats.

West Nile Virus risk and susceptibility in central California modeling dataset

The dataset was developed to support research intended to develop a spatially explicit model that explores environmental data related to the risk of exposure to West Nile Virus (WNV), and the susceptibility to WNV disease based on demographic data of the potentially affected population. The model was developed and then tested on census tracts in an identified hot spot of WNV in central California. The dataset contains (1) U.S. Census Bureau 2010 demographic data for 1,133 census tracks in the hotspot, and (2) and average mosquito habitat risk data for each of those census tracks.
