4D Printable Formulations of Mixed Low and High Molecular Weight Liquid Crystalline Units: A Versatile Route to Functional Soft Actuators

open access: yesMacromolecular Rapid Communications, Volume 47, Issue 9, 5 May 2026.
This work presents a practical approach for formulating 4D printable inks that incorporates substantial fractions of low molecular weight mesogens. By blending low molecular weight diacrylate or monoacrylate constituents with a high molecular weight main‐chain macromer, the resulting mixture proves suitable for direct ink writing, enabling mechanical ...

Exploring Pathways to the Persistence of Community Engagement in Co‐Management Across Social‐Ecological Conditions

open access: yesConservation Letters, Volume 19, Issue 3, May/June 2026.
ABSTRACT Evaluating sustained community engagement in co‐management is critical for designing durable governance with conservation potential, yet such persistence remains rarely assessed. We analyze 750 co‐management initiatives established under Chile's Territorial Use Rights for Fishing policy (1998–2021), examining persistence across conditions ...

Suppressing Metal–Molecule Charge Transfer With a Phosphorus Interlayer

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 8, 21 April 2026.
Phosphorus forms stable reconstructions with remarkable properties on various metal substrates. Here, using a spectroscopic approach, its role as an effective buffer layer on Cu(110) is demonstrated, preventing charge transfer to adsorbed Zn‐tetraphenylporphyrins (ZnTPP).

Unveiling nuclear localization signals in human arginine deiminase proteins

open access: yesProtein Science, Volume 35, Issue 4, April 2026.
Abstract Arginine iminohydrolases are a family of enzymes involved in the conversion of arginine to citrulline. There are five isoforms in humans (PADI1, 2, 3, 4, and 6). Some of them are observed experimentally in the cytoplasm and in the nucleus of the cell; for moving to the latter location, they must pass through the cell nuclear membrane by using ...

Multi‐Occupancy in CO2 Clathrate Hydrates: A Quantum Chemistry Study From Finite‐Size Cages to Crystals

open access: yesSmall Structures, Volume 7, Issue 4, April 2026.
How many CO2 molecules can a single clathrate‐like cage truly confine? This quantum‐chemistry study reveals multi‐occupancy and lattice‐driven stabilization effects. From isolated cages to full crystals, it uncovers how dispersion forces govern storage capacity, exposing sII hydrates as standout candidates for high‐density CO2 capture.
