Initiation: A Critical Step for High Activity and Stability in Ni‐Based Methane Dry Reforming Catalysts Supported on θ‐Al2O3

Angewandte Chemie, EarlyView.
A well‐defined Ni/θ‐Al2O3 catalyst prepared by surface organometallic chemistry exhibits sharp temperature‐dependent behavior in dry reforming of methane. At 850°C, a dynamic induction process forms a transient carbide‐like NiCx phase that enables continuous carbon removal and coke resistance, whereas at 800°C incomplete carbon insertion leads to ...

Ocean Acidification and Human Health [PDF]

International Journal of Environmental Research and Public Health, 2020
The ocean provides resources key to human health and well-being, including food, oxygen, livelihoods, blue spaces, and medicines. The global threat to these resources posed by accelerating ocean acidification is becoming increasingly evident as the world’s oceans absorb carbon dioxide emissions.

Effects of ocean acidification on Antarctic marine organisms: A meta‐analysis

Ecology and Evolution, 2020
Southern Ocean waters are among the most vulnerable to ocean acidification. The projected increase in the CO2 level will cause changes in carbonate chemistry that are likely to be damaging to organisms inhabiting these waters.

Projected pH reductions by 2100 might put deep North Atlantic biodiversity at risk [PDF]

, 2014
This study aims to evaluate the potential for impacts of ocean acidification on North Atlantic deep-sea ecosystems in response to IPCC AR5 Representative Concentration Pathways (RCPs).

Skeletal trade-offs in coralline algae in response to ocean acidification [PDF]

, 2014
Ocean acidification is changing the marine environment, with potentially serious consequences for many organisms. Much of our understanding of ocean acidification effects comes from laboratory experiments, which demonstrate physiological responses over ...

Iron biogeochemistry across marine systems progress from the past decade [PDF]

, 2010
Based on an international workshop (Gothenburg, 14–16 May 2008), this review article aims to combine interdisciplinary knowledge from coastal and open ocean research on iron biogeochemistry. The major scientific findings of the past decade are structured

Projected climate change impact on oceanic acidification

Carbon Balance and Management, 2006
Background Anthropogenic CO2 uptake by the ocean decreases the pH of seawater, leading to an 'acidification' which may have potential detrimental consequences on marine organisms 1.

Ongoing transients in carbonate compensation [PDF]

, 2010
Uptake of anthropogenic CO2 is acidifying the oceans. Over the next 2000 years, this will modify the dissolution and preservation of sedimentary carbonate.

Coccolithophore biodiversity controls carbonate export in the Southern Ocean [PDF]

, 2020
Southern Ocean waters are projected to undergo profound changes in their physical and chemical properties in the coming decades. Coccolithophore blooms in the Southern Ocean are thought to account for a major fraction of the global marine calcium ...
