Collisionless shock acceleration of quasi-monoenergetic ions in ultra-relativistic regime [PDF]

, 2019
Collisionless shock acceleration of carbon ions (C$^{6+}$) is investigated in the ultra-relativistic regime of laser-plasma interaction by accounting for the radiation reaction force and the pair production in particle-in-cell simulations. Both radiation

Interaction between Molten Al‐Killed Mn–B Steel and Carbon‐Bonded MgO Refractories Based on Recyclates

Advanced Engineering Materials, EarlyView.
High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

The Time Value of Carbon and Carbon Storage: Clarifying the terms and the policy implications of the debate [PDF]

The question of whether there is any value to the temporary storage of carbon is fundamental to climate policy design across a number of arenas, including physical carbon discounting in greenhouse gas accounting, the relative value of temporary carbon ...

A Thermodynamic 3D Model for the Simulation of Diffusion‐Controlled Alloying Processes in Heterogeneous Material Structures

Advanced Engineering Materials, EarlyView.
A numerical model resulting from irreversible thermodynamics for describing transport processes is introduced, focusing on thermodynamic activity gradients as the actual driving force for diffusion. Implemented in CUDA C++ and using CalPhaD methods for determining the necessary activity data, the model accurately simulates interdiffusion in aluminum ...

Full carbon accounting: mission impossible? [PDF]

Quantifying mitigation efforts against a large background variability is a demanding task, in which scientific complexity and manageable, transparent accounting systems have difficulty to meet.

How can we measure Scotland’s footprint? (and, once we have, what do we do with it?) [PDF]

, 2008
Recent months have seen a great deal of interest and consultation in Scotland regarding environmental and carbon accounting in general, and the calculation and use of ecological and carbon footprints in particular.

Influence of Sample Preparation and Processing Procedures on the Thermal Diffusivity of MgO‐C Refractories

Advanced Engineering Materials, EarlyView.
The thermal diffusivity of MgO‐C refractories is highly sensitive to sample preparation and processing procedures. In this article, the effects of coking sequence, machining conditions, structural inhomogeneity, and graphite coating application on measurements using laser flash apparatus are systematically investigated.

Temporary carbon storage and discount rates [PDF]

Several approaches have been proposed for accounting for temporary carbon sequestration in land-use change and forestry projects that are implemented to offset permanent emissions of carbon dioxide from the energy sector.

Summer CO2 evasion from streams and rivers in the Kolyma River basin, north-east Siberia [PDF]

, 2013
Inland water systems are generally supersaturated in carbon dioxide (CO2) and are increasingly recognized as playing an important role in the global carbon cycle.
