Ordered Hydrogen Bond Network Regulates Synergistic H and OH Spillover to Promote Alkaline Hydrogen Evolution

open access: yesAdvanced Energy Materials, EarlyView.
Ru─Ni nanoclusters are anchored on WC via a rapid microwave quasi‐solid‐state method to build an ordered flexible interfacial hydrogen bond network. This structure boosts water dissociation and enables barrier‐free H/OH transport via the Grotthuss mechanism, forming dual H‐to‐Ru and OH‐to‐Ni spillover pathways to overcome the key challenges of alkaline

An Investigation into the dynamics of the ocean current system off southern Greenland [PDF]

open access: yes, 2008
The ocean current system off Southern Greenland is a key component of the Earth’sclimate system due to its role in the regulation of the global thermohalinecirculation.

Contrasting responses to nutrient enrichment of prokaryotic communities collected from deep sea sites in the Southern Ocean [PDF]

open access: yes, 2013
Deep water samples (ca. 4,200 m) were taken from two hydrologically-similar sites around the Crozet islands with highly contrasting surface water productivities. Site M5 was characteristic of high productivity waters (high chlorophyll) whilst site M6 was

Understanding Egg Price Volatility and Policy Implications in the U.S. With Machine Learning

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Eggs are an inexpensive and sustainable source of proteins, but volatility in the U.S. egg prices has intensified in recent years, raising concerns over food affordability and market stability. This study examines the drivers of U.S. egg price dynamics over 2004–2025 using a two‐stage framework that combines LASSO‐based variable selection with

Changes in shelf waters due to air-sea fluxes and their influence on the Arctic Ocean circulation as simulated in the OCCAM global ocean model [PDF]

open access: yes, 2005
In this study we look at the ocean circulation of the Arctic Ocean in the high-resolution OCCAM global ocean model. The Arctic Ocean consists of deep basins surrounded by a large area of continental shelves, where cooling and ice formation play an ...

Proceedings of the Integrated Ocean Drilling Program 345: Hess Deep Plutonic Crust [PDF]

open access: yes, 2014
<p>Integrated Ocean Drilling Program (IODP) Hess Deep Expedition 345 was designed to sample lower crustal primitive gabbroic rock that formed at the fast-spreading East Pacific Rise (EPR) in order to test competing models of magmatic accretion and ...

Increasing model resolution improves but overestimates global mid-depth circulation simulation

open access: yesScientific Reports
Increasing the spatial resolution in climate models has significantly improved the simulation of global upper-layer ocean circulation. However, the ability of high-resolution models to accurately reproduce mid-depth circulation, in terms of strength and ...

Import Wheat Tenders and the Effects of the Russian Invasion

open access: yesAgribusiness, EarlyView.
ABSTRACT Risk and volatility for many commodities escalated sharply following the Russian invasion of Ukraine, creating numerous uncertainties for trading firms and importers. The purpose of this study is to analyze the bidding behavior in Egyptian wheat import tenders in the pre‐ and post‐invasion periods.

Cameras and carcasses: historical and current methods for using artificial food falls to study deep-water animals [PDF]

open access: yes, 2007
Deep-ocean animals remain poorly understood compared to their shallow-water relatives, mainly because of the great cost and difficulty involved in obtaining reliable ecological data.

Ferritin Iron Mineralisation: Route of Fe3+ Transfer From the Ferroxidase Centre to the Inner Cavity of Human H‐Chain Ferritin

open access: yesAngewandte Chemie, EarlyView.
Proposed mechanism for Fe3+ transport from the FoC (sites 1 and 2) of human H‐chain ferritin following oxidation of the di‐Fe2+ form. Glu61, aided by the flexibility of its sidechain, plays a key role in coordinating Fe3+ at three sites (3, 4 and 5) that mark out the transit route.
