Degradable Donor‐Acceptor Polymeric Mixed Ionic‐Electronic Conductors for Transient Electronics

open access: yesAdvanced Materials Technologies, EarlyView.
Here, we report degradable donor–acceptor (D–A) polymeric mixed ionic‐electronic conductors for transient electronics. We take a systematic side chain engineering approach to elucidate how molecular‐level modifications of donor–acceptor (D–A) polymer structures can satisfy demands that are often conflicting: degradability, charge carrier transport, and

Visible‐Light Photoprogrammable Transistors Enabled by an All‐Organic Triplet‐Sensitized Diarylethene Channel Layer

open access: yesAdvanced Optical Materials, EarlyView.
All‐organic channel‐layer OFETs are shown to enable visible‐light photoprogramming via triplet‐sensitized diarylethene switching. Preferential localization of the photoswitch and organic sensitizer in intercrystalline amorphous domains preserves polymer crystalline packing while ensuring short‐range Dexter‐type triplet–triplet energy transfer and solid‐

Bird community patterns in sub–Mediterranean pastures: the effects of shrub cover and grazing intensity

open access: yesAnimal Biodiversity and Conservation, 2011
Shrubs are widely considered a threat to grassland biodiversity. We investigated the effects of shrub cover and grazing intensity on bird communities in sub–Mediterranean pastures in Bulgaria.

Echinoderm‐Inspired Autonomy for Soft‐Legged Robots

open access: yesAdvanced Robotics Research, EarlyView.
Inspired by echinoderms, a modular soft robot achieves autonomous phototaxis without a central controller or explicit communication. Each limb independently adapts its actuation timing through local sensing and short‐term memory. Coordination emerges purely from physical interactions, demonstrating resilience to changes in morphology, environment, and ...

Fertilization and oversowing on natural grassland: effects on pasture characteristics and yearling steers performance

open access: yesRevista Brasileira de Zootecnia, 2011
The objective of this study was to evaluate the vegetal and animal production of a natural pasture on a Mollisol soil in the region of Campanha, in RS. The experimental design consisted of complete randomized blocks with three replicates, which enables ...

Agriculture production versus biodiversity protection: what role for north-south unconditional transfers? [PDF]

open access: yes
In developing countries, biodiversity is often threatened by the development of agricultural production because natural habitats are destroyed by the conversion of forests, wetlands or natural pastures into arable land.

Gait Analysis of Pak Biawak: A Necrobot Lizard Built using the Skeleton of an Asian Water Monitor (Varanus Salvator)

open access: yesAdvanced Robotics Research, EarlyView.
Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.

From Lab to Landscape: Environmental Biohybrid Robotics for Ecological Futures

open access: yesAdvanced Robotics Research, EarlyView.
This Perspective explores environmental biohybrid robotics, integrating living tissues, microorganisms, and insects for operation in real‐world ecosystems. It traces the leap from laboratory experiments to forests, wetlands, and urban environments and discusses key challenges, development pathways, and opportunities for ecological monitoring and ...

Ticks on pastures and on two breeds of cattle in the Eastern Cape province, South Africa

open access: yesOnderstepoort Journal of Veterinary Research, 2011
Many studies on the population dynamics of questing ticks on pastures and of parasitic ticks on cattle have been conducted. Few, however, have attempted to link the two in a single study.
