Queen conch aquaculture remains a conservation symbol and is not yet a fisheries solution

open access: yesOryx
Conservation aquaculture, defined as cultivating aquatic organisms to manage or replenish natural populations, has been advocated as a strategy to enhance fisheries production and help restore declining populations.

Mechanically Robust and Depolymerizable Polyesters With Near‐Complete Monomer Recovery for Circular Additive Manufacturing

open access: yesAdvanced Materials, EarlyView.
A sustainable δ‐lactone‐based polymer platform enables multimodal additive manufacturing through DLP, DIW, and FFF, combining tunable crystallinity, photocurable networks, mechanical robustness, and functional response. The printed materials can be mechanically reprocessed and chemically depolymerized into recoverable monomers, demonstrating a closed ...

Contrasting genomic consequences of anthropogenic reintroduction and natural recolonization in high‐arctic wild reindeer

open access: yesEvolutionary Applications, 2023
Anthropogenic reintroduction can supplement natural recolonization in reestablishing a species' distribution and abundance. However, both reintroductions and recolonizations can give rise to founder effects that reduce genetic diversity and increase ...

Rapid Room‐Temperature Ethanol Sensing in Bi2MoO6/rGO Heterostructures: Weak Adsorption‐Driven Charge Modulation

open access: yesAdvanced Materials Technologies, EarlyView.
This work establishes Bi2MoO6/rGO heterostructures as a mechanism‐guided platform for high‐performance room‐temperature ethanol gas detection by showing that modest adsorption, in conjunction with dynamic interfacial band modulation, enables rapid charge‐transfer.

Immediate Organic Room‐Temperature Phosphorescence in Programmable Luminescent Tags Enabled by Oxygen‐Free Fabrication

open access: yesAdvanced Materials Technologies, EarlyView.
Programmable luminescent tags based on organic room‐temperature phosphorescence are shown to be governed by oxygen incorporation during fabrication. Oxygen‐free processing enables immediate phosphorescence activation, controlled thermal preconditioning, and tunable activation doses.
