A sustainable ecofriendly-synthesis of carbon foams from sugarcane, benefiting the waste to obtain activated carbons

open access: yesIndustrial Crops and Products
This study demonstrates, for the first time, that unprocessed sugarcane juice (SCJ) can be used directly as a sustainable precursor for the synthesis of carbon foams, yielding materials comparable to those obtained from commercial sucrose while avoiding ...

Advanced Packed-Bed Ca-Cu Looping Process for the CO2 Capture From Steel Mill Off-Gases

open access: yesFrontiers in Energy Research, 2020
A novel configuration of the Ca-Cu looping process based on dynamically operated packed-bed reactors is proposed to convert blast furnace gas (BFG) into H2/N2 and highly concentrated CO2, accompanied by a large amount of high-temperature heat ...

Improved Cerrado Wetland Mapping Through Seasonal Moisture Metrics, Terrain Information and Semantic Segmentation

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Brazil's Cerrado valley wetlands—swamp savanna and gallery forest—are highly important for the biome's water cycle and carbon storage and are susceptible to degradation from the impacts of land use expansion and the climate crisis. In support of their detailed monitoring and assessment, we developed and tested a transferable mapping approach that ...

Comprehensive framework for assessing and optimizing existing research networks

open access: yesConservation Biology, EarlyView.
Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

Direct Ink Writing of 3D‐Structured All‐Carbon Electrodes with High Electrical Conductivity for (Vanadium) Redox Flow Batteries

open access: yesAdvanced Science
Redox flow batteries are attractive systems for large‐scale energy storage due to their capability to uncouple energy and power but still need to make several improvements to reach full commercial scale.

Introduced dung beetles suppress methane emissions from cattle dung and alter the temporal dynamics of greenhouse gas flux Los escarabajos peloteros introducidos suprimen las emisiones de metano del estiércol de ganado y alteran la dinámica temporal del flujo de gases de efecto invernadero Besouros coprófagos introduzidos suprimem as emissões de metano do esterco bovino e alteram a dinâmica temporal do fluxo de gases de efeito estufa

open access: yesEcological Entomology, EarlyView.
Dung beetles suppressed cumulative methane flux from cattle dung by 85% and reduced total greenhouse gas emissions by 18%. Beetle activity accelerated initial CO2 release but did not alter total cumulative flux. N2O and NH3 fluxes were transient and not consistently driven by beetle presence.

Mercury Removal by Carbon Materials with Emphasis on the SO2–Porosity Relationship

open access: yesChemistryOpen
Mercury is a pollutant of great global concern. Although numerous studies have been carried out for its removal from energy production processes, there are still some gaps in this field that must be filled to improve the development of adsorbents ...
