Habitat enhancing marine structures: Creating habitat in urban waters [PDF]

open access: yes, 2010
Although maritime regions support a large portion of the world’s human population, their value as habitat for other species is overlooked. Urban structures that are built in the marine environment are not designed or managed for the habitat they ...

High‐Entropy Metal Phosphide for Efficient Hydrogen Conversion Reactions

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this study, high‐entropy metal phosphide nanoparticles were synthesized via a cation‐binding phosphate–resin heating treatment strategy. Mn incorporation in Co0.62Fe0.20Ni0.14Cu0.23Mn0.38P effectively optimized the electronic structure, accelerated electron transfer among metal sites, lowered the free energy of hydrogen adsorption/desorption, and ...

Rapidly rotating neutron star progenitors

open access: yes, 2016
Rotating proto-neutron stars can be important sources of gravitational waves to be searched for by present-day and future interferometric detectors. It was demonstrated by Imshennik that in extreme cases the rapid rotation of a collapsing stellar core ...

RuO2‐Based High‐Entropy Oxide and Its Asymmetric Catalysis on Polysulfide Conversion in Lithium–Sulfur Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
RuO2‐based high‐entropy metal oxide shows an asymmetric catalysis on polysulfide conversion with an inferior kinetics enhancement of polysulfide generation, but a superior promotion of Li2S deposition, which greatly favors the inhibition of shuttle effect and the improvement of battery performance. High‐entropy oxides with five or more metal components

Helicopter EMS Transport Outcomes Literature: Annotated Review of Articles Published 2007–2011

open access: yesEmergency Medicine International, 2012
Helicopter EMS (HEMS) and its possible association with outcomes improvement continues to be a subject of discussion. As is the case with other scientific discourse, debate over HEMS usefulness should be framed around an evidence-based assessment of the ...
