Special Issue “Fabrication and Characterization of Nanostructured Carbon Electrodes”

Nanomaterials, 2023
The nanostructured carbon materials are promising electrode materials and have been widely studied owing to their tailorable structures, which offer large active sites and reduce the path of transport for mass and charge and thus provide fast pathways ...

The Nordic Seas carbon budget: Sources, sinks, and uncertainties [PDF]

, 2011
A carbon budget for the Nordic Seas is derived by combining recent inorganic carbon data from the CARINA database with relevant volume transports. Values of organic carbon in the Nordic Seas' water masses, the amount of carbon input from river runoff ...

Health impacts of active transportation in Europe [PDF]

, 2016
Policies that stimulate active transportation (walking and bicycling) have been related to heath benefits. This study aims to assess the potential health risks and benefits of promoting active transportation for commuting populations (age groups 16-64 ...

Model-based analysis of solute transport and potential carbon mineralization in the active layer of a hillslope underlain by permafrost with seasonal variability and climate change [PDF]

The Cryosphere
Permafrost carbon, stored in frozen organic matter across vast Arctic and sub-Arctic regions, represents a substantial and increasingly vulnerable carbon reservoir.

Bomb-14C analysis of ecosystem respiration reveals that peatland vegetation facilitates release of old carbon [PDF]

, 2009
The largest terrestrial-to-atmosphere carbon flux is respired CO2. However, the partitioning of soil and plant sources, understanding of contributory mechanisms, and their response to climate change are uncertain.

The Importance of Mesozooplankton Diel Vertical Migration for Sustaining a Mesopelagic Food Web

Frontiers in Marine Science, 2019
We used extensive ecological and biogeochemical measurements obtained from quasi-Lagrangian experiments during two California Current Ecosystem Long-Term Ecosystem Research cruises to analyze carbon fluxes between the epipelagic and mesopelagic zones ...

Modeling the contribution of micronekton diel vertical migrations to carbon export in the mesopelagic zone [PDF]

Biogeosciences
Micronekton plays a significant but often overlooked role in carbon transport within the ocean. Using a one-dimensional trait-based model, we simulated the diel vertical migrations (DVMs) of micronekton and their carbon production through respiration ...

Preservation of organic carbon during active fluvial transport and particle abrasion [PDF]

Geology, 2019
Abstract Oxidation of particulate organic carbon (POC) during fluvial transit releases CO2 to the atmosphere and can influence global climate. Field data show large POC oxidation fluxes in lowland rivers; however, it is unclear if POC losses occur predominantly during in-river transport, where POC is in continual motion within an aerated

Monitoring of the carbon footprint of road freight transport activities

Monitoring of the carbon footprint of road freight transport activities, 2023
The article analyzes the process of monitoring the carbon footprint of road freight transport. The significance of the influence of road transport on climate warming is revealed. In order to select the most appropriate method for calculating pollution with greenhouse gases, the methodology for calculating pollution is analyzed.
