Comparative field‐scale assessment of TLUD and Kon‐Tiki biochar systems: agronomic performance and net CO2e‐based techno‐economics

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 4, Page 1762-1780, July/August 2026.
Abstract Post‐harvest agricultural residues in Latin America are commonly underutilized, leading to greenhouse gas emissions and lost opportunities for bio‐based value creation. This study tests the hypothesis that decentralized, farmer‐scale pyrolysis technologies can deliver comparable agronomic benefits while exhibiting distinct techno‐economic and ...

Magnetic lipase B from Candida antarctica (CALB) biocatalyst for integrated valorization of tilapia by‐products and biodiesel biorefining

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 4, Page 1835-1860, July/August 2026.
Abstract The immobilization of lipase B from Candida antarctica (CALB) on an amino‐epoxy functionalized magnetic support (Fe3O4‐PEI‐DGEBA) resulted in a highly stable and efficient biocatalyst for biofuel production from tilapia oil. The synthesized support was characterized using scanning electron microscopy, transmission electron microscopy, X‐ray ...

Processamento de compósitos termoestruturais de carbono reforçado com fibras de carbono [PDF]

Journal of Aerospace Technology and Management, 2009
The present work describes the processes used to obtain thermostructural Carbon/Carbon composites. The processing of these materials begins with the definition of the architecture of the carbon fiber reinforcement, in the form of stacked plies or in the form of fabrics or multidirectional reinforcement. Incorporating fiber reinforcement into the carbon

Lichen bleaching as a response to long‐term experimental warming in the High Arctic

Functional Ecology, Volume 40, Issue 7, Page 2318-2331, July 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Lichens are an important component of Arctic ecosystems. Studies have indicated a decline in the abundance of Arctic lichens during recent decades, which is often attributed to competitive pressure from vascular plants.

Sequestro de carbono

DRd - Desenvolvimento Regional em debate, 2019
A Bacia Hidrográfica do Rio Canoinhas (BHRC) ocupa uma superfície de 1.663km², representando cerca de 16% da área do Planalto Norte Catarinense (PNC). Esta região era originalmente coberta por ecossistemas naturais com predomínio da Floresta Ombrófila Mista (FOM), uma das formações do bioma Mata Atlântica. A Mata de Araucárias apresenta elevados níveis
