Electron hole pair mediated vibrational excitation in CO scattering from Au(111): incidence energy and surface temperature dependence.
We investigated the translational incidence energy (Ei) and surface temperature (Ts) dependence of CO vibrational excitation upon scattering from a clean Au(111) surface. We report absolute v = 0 → 1 excitation probabilities ...
Search for supersymmetry with jets, missing transverse momentum and at least one hadronically decaying τ lepton in proton–proton collisions at √ s = 7 TeV with the ATLAS detector
A search for production of supersymmetric particles in final states containing jets, missing transverse momentum, and at least one hadronically decaying τ lepton is presented. The data were recorded by the ATLAS experiment ...
The Computational Complexity of Delay Management
Delay management for public transport consists of deciding whether vehicles should wait for delayed transferring passengers, with the objective of minimizing the overall passenger discomfort. This paper classifies the ...
Salt stress induces the formation of a novel type of ‘pressure wood’ in two Populus species
Salinity causes osmotic stress and limits biomass production of plants. The goal of this study was to investigate mechanisms underlying hydraulic adaptation to salinity. • Anatomical, ecophysiological and transcriptional ...
Metallic Iron for Water Treatment: A Critical Review
Water treatment with metallic iron (Fe0) is still based on the premise that Fe0 is a reducing agent. An alternative concept stipulates that contaminants are removed by adsorption, co-precipitation and size-exclusion in a ...
Testing the suitability of metallic iron for environmental remediation: Discoloration of methylene blue in column studies
A new method to correlate intrinsic reactivity and treatability efficiency of metallic iron (Fe0) was evaluated. A 2.0 mg L-1 methylene blue (MB) solution was used in gravity fed column experiments. The intrinsic reactivity ...
Aqueous contaminant removal by metallic iron: Is the paradigm shifting?
Chemical reduction has long dominated the thinking about the mechanism of aqueous contaminant removal in the presence of metallic iron (e.g. Fe0/H2O systems). However, a large body of experimental evidence indicates that ...
Designing laboratory metallic iron columns for better result comparability
Despite the amount of data available on investigating the process of aqueous contaminant removal by metallic iron (Fe0), there is still a significant amount of uncertainty surrounding the design of Fe0 beds for laboratory ...
Investigating the Release of Co-precipitated Uranium from Iron Oxides
The removal of uranium (VI) in zerovalent iron permeable reactive barriers and wetlands can be explained by its association with iron oxides. The long term stability of this immobilized U is yet to be addressed. The ...
Metallic iron for water treatment: Healing a research community
Despite two decades of intensive research on using metallic iron (Fe0) for environmental remediation and water treatment, basic concerns about their efficiency still prevail. This communication presents the basic idea of ...
