Mechanochromism of Glassy Polymers Enabled by a Loop‐Forming Supramolecular Mechanophore

open access: yesAdvanced Functional Materials, EarlyView.
The supramolecular mechanophore LOOP is covalently introduced into glassy polymers, capable of reporting force‐induced pre‐failure damage and local fracture events in polymer glasses. Under different mechanical deformation modes, including grinding, tensile stretching, and scratching, LOOP probes irreversible events in polymer glasses through a ...

Metal–Organic Frameworks for Gaseous Pollutant Management: From Capture to Neutralization and Reutilization

open access: yesAdvanced Functional Materials, EarlyView.
This review maps how MOFs can manage hazardous gases by combining adsorption, neutralization, and reutilization, enabling sustainable air‐pollution control. Covering chemical warfare agent simulants, SO2, NOx, NH3, H2S, and volatile organic compounds, it highlights structure‐guided strategies that boost selectivity, water tolerance, and cycling ...

Velocity sections of the upper mantle under the oceans

open access: yesГеофизический журнал, 2016
We constructed the models of the distribution of longitudinal seismic waves velocities for the upper mantle oceanic regions: mid-ocean ridges (MOR), basins, trenches, island arcs and coastal ridges, back-arc troughs (BAT).

Fostering ocean empathy through future scenarios

open access: yesPeople and Nature, 2021
Empathy for nature is considered a prerequisite for sustainable interactions with the biosphere. Yet to date, empirical research on how to stimulate empathy remains scarce. Here, we investigate whether future scenarios can promote greater empathy for the

Building on Rio+20: What This Means for Fisheries Management [PDF]

open access: yes, 2012
Almost every member State of the United Nations attended the June 2012 United Nations Conference on Sustainable Development (Rio+20), and agreed by consensus to the outcome document, "The Future We Want." That outcome document was then endorsed by ...

Metachromatic Butterfly Bile Pigments for Multi‐Level Optical Security Films

open access: yesAdvanced Functional Materials, EarlyView.
Bio‐derived optical security materials are manufactured by embedding butterfly‐based pigments in polymer films. Tunable color and fluorescence responses arise from concentration‐controlled metachromasy, enabling spatially encoded patterns with distinct visible, UV‐active, and spectral signatures.

Assessment of the NASA carbon monitoring system wet carbon stakeholder community: data needs, gaps, and opportunities

open access: yesEnvironmental Research Letters, 2023
Wet carbon (WC) ecosystems are a critical part of the carbon cycle, yet they are underrepresented in many policy and science communities due to the relative under-investment in stakeholder and boundary organizations.
