Superior through‐plane thermal conductivity in carbon fibers/spherical graphene/epoxy laminated composites for low‐altitude aircrafts

InfoMat, EarlyView.
To address the low through‐plane thermal conductivity (λ⊥) of carbon fiber/epoxy composites, which poses thermal management challenges in the expanding low‐altitude economy, we incorporated spherical thermally reduced graphene (s‐TRG) as a bridging filler. This architectural design achieved a λ⊥ of 2.73 W m–1 K–1 at 10 wt% loading.

Carbon Stock and Environmental Variations of Typical Plantations in Mufu Mountain in Hubei Province, China

Land Degradation &Development, EarlyView.
ABSTRACT Forest ecosystems play a critical role in the global carbon cycle. As a significant terrestrial carbon sink, plantations exhibit carbon stock patterns that are shaped by tree species composition, stand structure, and environmental conditions. Here, we investigated typical plantation types in the Mufu Mountain, Hubei Province.

Data‐Based Detection of Antagonistic Agents in a Robot Swarm Solving a Dynamic Coverage Task

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Robot swarms can be deployed as moving surveillance systems, for instance, as mobile anti‐poaching systems for monitoring wildlife and detecting poaching activities. Since poachers have an interest in evading detection, robots are at risk of being hijacked and manipulated to behave antagonistically, for example, to prevent the correct ...

An interdisciplinary review of the interplay of conflict, socio‐economic factors, and land cover and vegetation dynamics in Colombia

PLANTS, PEOPLE, PLANET, EarlyView.
Colombia's forests play a crucial role in preserving biodiversity and mitigating climate change, but they are currently facing severe degradation, particularly after the 2016 Peace Agreement. Our literature review highlights a growing research interest in this topic and demonstrates how interdisciplinary approaches combining diverse methods can enhance
