Sources of uncertainties in modelling black carbon at the global scale [PDF]

, 2010
Our understanding of the global black carbon (BC) cycle is essentially qualitative due to uncertainties in our knowledge of its properties. This work investigates two source of uncertainties in modelling black carbon: those due to the use of different ...

Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

Advanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

Fishing impacts on the marine inorganic carbon cycle [PDF]

Journal of Applied Ecology, 2009
Summary1. Teleost fish excrete precipitated carbonate and make significant contributions to the marine inorganic carbon cycle at regional and global scales. As total carbonate production is linked to fish size and abundance, fishing is predicted to affect carbonate production by modifying fish abundance and size‐structure.2.

Polarizable Vanadium Dipoles Promote Water Dissociation on Vanadium‐Based Metal Organic Framework

Advanced Functional Materials, EarlyView.
The polarization of unpaired V 3d electrons weakens the H─O bond to improve water dissociation by the dual Vδ+:O─H and Pλ−:H─O coupling hydrogen bonds formation and relaxation. P@V‐MOF electrocatalyst shows low overpotentials (94 mV in acid, 178 mV in neutral, and 77 mV in alkaline solutions) with excellent stability for effective overall water ...

Substantial stores of sedimentary carbon held in mid-latitude fjords [PDF]

Biogeosciences, 2016
Quantifying marine sedimentary carbon stocks is key to improving our understanding of long-term storage of carbon in the coastal ocean and to further constraining the global carbon cycle.

Climate change and ocean acidification impacts on lower trophic levels and the export of organic carbon to the deep ocean [PDF]

, 2013
Most future projections forecast significant and ongoing climate change during the 21st century, but with the severity of impacts dependent on efforts to restrain or reorganise human activity to limit carbon dioxide (CO2) emissions.

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

Advanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Divergent leaf senescence changes in meadows, steppes, and cultivated vegetation on the Qinghai–Tibetan Plateau

Global Ecology and Conservation
Temporal changes in autumn leaf senescence dates and their drivers across meadows, steppes, and cultivated vegetation on the Qinghai–Tibetan Plateau (QTP) remain poorly understood.

Planktonic foraminifera organic carbon isotopes as archives of upper ocean carbon cycling

Nature Communications, 2022
Our understanding of ancient organic carbon cycling in marine environments is limited. Here the authors developed a method to reconstruct upper ocean organic carbon chemistry in the geological past, which when applied, can help to create a better ...
