Strain‐Modulated Engineering of High‐Entropy Vanadium‐Based Chalcogenide for Sustainable Water Oxidation

open access: yesSmall, EarlyView.
High‐entropy metal chalcogenides (HEMC) incorporating five equimolar transition metals and sulfur were synthesized via an efficient solvothermal method. The resulting HEMC exhibits a single‐phase pyrite (Pa‐3) crystal structure, which was thoroughly characterized using advanced structural analysis techniques. As an anode material, the HEMC demonstrates

Suppression Characteristics and Mechanism of MCA@ADP‐MMT Composite Powder on Aluminum Powder Explosion

open access: yesSafety Science and Technology, EarlyView.
MCA@ADP‐MMT can effectively slow down the combustion of Al powder and suppress the occurrence of explosion through the synergistic effect of multiple suppression mechanisms including dilution, quenching, and barrier. ABSTRACT The advancement of precision machining technology has heightened safety concerns regarding aluminum (Al) powder explosions in Al

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

The Principle of “Ultima Ratio” And/Or the Principle of Proportionality

open access: yesOñati Socio-Legal Series, 2013
The ultima ratio principle is a highly topical subject. The author describes the common grounds and different perspectives of “ultima ratio” on the one hand and/or the principle of proportionality in German criminal and public law on the ...

Climate‐induced shifts in long‐term tropical tree reproductive phenology: Insights from species dependent on and independent of biotic pollination

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The dependence on biotic pollination may constrain plant phenological responses because flowering time ultimately defines reproductive success. We proposed a local‐scale study combining long‐term phenology and experimental data to evaluate how a key functional trait—the

The Principle of “Ultima Ratio” And/Or the Principle of Proportionality

open access: yesOñati Socio-Legal Series, 2012
The ultima ratio principle is a highly topical subject. The author describes the common grounds and different perspectives of “ultima ratio” on the one hand and/or the principle of proportionality in German criminal and public law on the other hand.

When and why to give shorebirds a head start

open access: yesConservation Biology, EarlyView.
Abstract Headstarting is a translocation technique involving the hatching or rearing of wild eggs or young in captivity and the release of those individuals back to the wild at or before independence. It has been trialed as a conservation intervention for shorebirds over recent decades to improve the population trend of target populations by increasing

DERECHO PENAL COMO ULTIMA RATIO. HACIA UNA POLÍTICA CRIMINAL RACIONAL

open access: yesIus et Praxis, 2008
Aun cuando nadie duda que el principio de ultima ratio constituye un límite esencial al poder punitivo del Estado, las dificultades se presentan cuando deben fijarse criterios que brinden un contenido material, sobre todo considerando el basamento ...
