A Sustainable Bio‐Based Epoxy Thermoset as a High‐Performance Alternative to BPA‐Based Resins

open access: yesAdvanced Science, EarlyView.
A rigid–flexible bio‐based epoxy network integrates soybean oil, lignin, and maleic anhydride to overcome the strength–toughness–sustainability trade‐off of conventional BPA epoxy. The thermoset delivers excellent performance as both a structural adhesive and a matrix for glass‐fabric composites, while enabling pH‐responsive degradation, environmental ...

The relationship between resilience and sustainable development of ecological-economic systems [PDF]

open access: yes
Resilience as a descriptive concept gives insight into the dynamic properties of a system. Sustainability as a normative concept captures basic ideas of inter- and intragenerational justice.

Experimenting with ecosystem interaction networks in search of threshold potentials in real-world marine ecosystems [PDF]

open access: yes, 2014
Thresholds profoundly affect our understanding and management of ecosystem dynamics, but we have yet to develop practical techniques to assess the risk that thresholds will be crossed.

Space‐Time Metasurface Antenna Enabled High‐Dimensional Electromagnetic Modulation for Intrinsic Physical Layer Security

open access: yesAdvanced Science, EarlyView.
The concept of high‐dimensional EM modulation using the STMA for physical layer secure communication is illustrated in figure. The STMA consists of a series of programmable unit cells, with 1‐bit reconfigurable phase states (0/π). The STMA is excited by a monochromatic continuous wave (CW) at frequency fc and controlled by a field‐programmable gate ...

Araucaria bidwillii genomics suggest Indigenous Peoples broadened translocation practices in response to settler colonialism

open access: yesPeople and Nature
Retracing past anthropogenic dispersal of culturally important taxa offers insights to the biogeographic history of species, as well as the history of the people who interacted with them.

Estimating the Resilience Value of Soil Biodiversity in Agriculture: A Stochastic Simulation Approach [PDF]

open access: yes
Characteristic of ecosystems is that different organisms can have similar functions and hence provide similar ecosystem services. Consequently functional diversity can maintain the rate of services despite environmental fluctuations.

The Plant‐to‐Plant Circular Strategy: Coupling Photodegradation and Phytoremediation With Plant‐Based Nanomaterials for Plastic Degradation

open access: yesAdvanced Science, EarlyView.
Plant‐based nanomaterials derived from alfalfa serve as dual‐function catalysts, coupling photodegradation and phytoremediation to degrade polyethylene under UV‐A light and in soil. The nanomaterials work synergistically with alfalfa and soil microbes, achieving efficient plastic breakdown without trophic transfer.

Examining resilience and vulnerability as concepts conditional upon human values: a review [PDF]

open access: yes
Whilst there has been progress in understanding the role that values play in determinations of vulnerability and resilience, I suggest some key points continue to be overlooked.

Spatial variation in functional group diversity in a sandflat benthic community: implications for ecosystem resilience [PDF]

open access: yes, 2013
The resilience of macrobenthic communities to environmental stress depends upon the vulnerability, adaptability and connectivity of species. Recent studies suggest that the function(s) species perform may be more influential in driving community response
