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 ...

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 ...

Resonance‐Enhanced Four‐Wave Mixing Imaging for Mapping Defect Regions in Vanadium‐Doped WS2 Monolayers

open access: yesSmall Methods, EarlyView.
Resonant four‐wave mixing (FWM) microscopy reveals a spatial modulation of the third‐order nonlinear optical response in vanadium‐doped WS2 monolayers. This robust nonlinear contrast technique tracks the preferential accumulation of vanadium dopants along the structural bisection lines of the synthesized flakes.

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 ...

Good days, bad days: Weather patterns driving bryophyte carbon‐exchange dynamics in tropical rainforest canopies

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The physiology of tropical mosses, liverworts and lichens may be challenged by the daily weather patterns in lowland rainforests. Since these poikilohydric organisms can only photosynthesize and respire when hydrated, unfavourable timing of light and water availability (

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 ...
