Shear Properties of Carbon Fiber/Phenolic Resin Composites Heat Treated at High Temperatures

open access: yesJournal of Aerospace Technology and Management, 2016
Carbon fiber/phenolic resin composites have long been used as ablative materials in rocketry. Ablation is a complex multiscale problem where radiative and convective heating leads to the pyrolysis of phenolic resin matrix, resulting in the formation of a

Across the edge: Spatial segregation drives community structure in tri‐trophic multilayer networks at a forest–grassland edge

open access: yesJournal of Animal Ecology, Volume 94, Issue 11, Page 2205-2219, November 2025.
This study reveals how forest–grassland edges act as ecological barriers that shape tri‐trophic interaction networks. Using multilayer network theory, it uncovers how species influence and biodiversity patterns emerge across spatial layers, offering novel insights into edge‐driven community assembly and conservation in fire‐prone mosaics.

Mapping Resilient Landscapes to Climate Change in a Megadiverse Country

open access: yesGlobal Change Biology, Volume 31, Issue 10, October 2025.
Our mapping of terrestrial climate‐resilient sites for biodiversity across Brazil identifies sites with greater chances of providing suitable conditions for species to persist under regional climate change. Landscape resilience information has the potential to be used to effectively guide decision‐making and public policy on strategies for conservation,
