Nitrogen controls on plant carbon-use efficiency

, 2020
Nitrogen (N) is essential for plant growth and might progressively limit the fertilization effect of elevated atmospheric CO2 (eCO2), which affects predictions of future land carbon (C) uptake and storage. Within the present thesis, I develop a dynamic N acquisition model that allows plants to actively invest C into different symbiotic N acquisition ...

Corrosion and Process Analysis of a Preoxidized MgO Recyclate‐Based Cermet Anode in Laboratory‐Scale Na‐Cryolite Molten Salt Electrolysis of Aluminum at 1000°C

Advanced Engineering Materials, EarlyView.
EDX elemental map of the pre‐oxidized MgO–steel cermet anode cross section after electrolysis. The development of inert anodes for aluminum electrolysis remains challenging due to the high corrosivity of cryolite‐based melts at 950°C–1000°C. This study investigates the corrosion and process behavior of a carbon‐free MgO–steel cermet anode derived from ...

The Impact of Development on CO2 Emissions: A Case Study for Bangladesh until 2050 [PDF]

Bangladesh, a country with a population of 160 million, is currently contributing 0.14 percent to the world’s emission of carbon dioxide (CO2). However, mostly due to a growing population and economic growth (which both lead to an increase in energy ...

Microbial carbon use efficiency: accounting for population, community, and ecosystem-scale controls over the fate of metabolized organic matter [PDF]

, 2016
Microbial carbon use efficiency (CUE) is a critical regulator of soil organic matter dynamics and terrestrial carbon fluxes, with strong implications for soil biogeochemistry models.

Divergence in global plant carbon use efficiency across data-driven estimates, satellite product, and process-oriented models

Ecological Indicators
Plant carbon use efficiency (CUE)—the proportion of net to gross primary productivity (NPP/GPP)—is a critical indicator of terrestrial carbon cycling, yet its global patterns and trends remain uncertain due to challenges in directly measuring carbon flux.

Interaction of MgO Recyclate‐Based Cermet Anode With KF‐AlF3‐Al2O3 at 800°C During Laboratory Scale Aluminum Molten Salt Electrolysis

Advanced Engineering Materials, EarlyView.
A carbon‐free, as‐sintered MgO–steel cermet anode, fabricated via cold isostatic pressing using MgO–C refractory recyclate, was evaluated under laboratory‐scale K‐cryolite electrolysis at 800°C. Operation at this reduced temperature, combined with the electrolyte's limited electrical conductivity, led to an increase in cell voltage.

Toward Low‐Consumable Anodes: Process Simulation and Prospective Life Cycle Assessment of NiFe2O4‐NiO‐Ni‐Cu vs. Prebaked Anodes for Aluminum Production with use of Molten Salt Electrolysis

Advanced Engineering Materials, EarlyView.
Low‐consumable nickel ferrite‐based anodes for the Hall–Héroult process are compared with conventional prebaked carbon anodes using thermodynamic simulation and prospective life cycle assessment under contrasting future electricity system pathways from 2025 to 2050.

Agent-based control for decentralised demand side management in the smart grid

, 2011
Central to the vision of the smart grid is the deployment of smart meters that will allow autonomous software agents, representing the consumers, to optimise their use of devices and heating in the smart home while interacting with the grid.

The Carbon Budget of Land Conversion: Sugarcane Expansion and Implications for a Sustainable Bioenergy Landscape in Southeastern United States

GCB Bioenergy
The expansion of sugarcane onto land currently occupied by improved (IMP) and semi‐native (SN) pastures will reshape the U.S. bioenergy landscape. We combined biometric, ground‐based and eddy covariance methods to investigate the impact of sugarcane ...
