Thiolate Salt Mediated Dynamic Silyl Ether Exchanges for Polymer Network Design and Deconstruction

open access: yesMacromolecular Rapid Communications, EarlyView.
This work introduces thiolate salts as mediators for dynamic silyl ether exchange. This platform enables the synthesis of reprocessable covalent adaptable polymer networks (CANs) and allows for sterically controlled, and tunable deconstruction of silyl ether‐containing thermosets.

Weakly Convex Ridge Regularization for 3D Non‐Cartesian MRI Reconstruction

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose While highly accelerated non‐Cartesian acquisition protocols significantly reduce scan time, they often entail long reconstruction delays for 3D data. Deep learning–based reconstruction methods can alleviate this, but typically rely on complex, highly parametrized architectures.

Mechanical Recycling of Hybrid Polypropylene/Recycled Carbon Fiber/Hemp Composite Wall Panels: A Comparative Study of Compression and Injection Molding

open access: yesPolymer Composites, EarlyView.
Mechanical recycling pathways for hybrid PP/rCF/hemp composite wall panels via compression and injection molding. ABSTRACT Circular economy increasingly influences sectors such as automotive, packaging, and building‐construction. The rise of circular economy in these sectors is driven by the generation of large volumes of waste that end up in landfills,

Fabrication of amorphous lamellar freestanding poly(N‐dodecyl acrylamide) films and their mechanical properties

open access: yesPolymer International, EarlyView.
A freestanding film of completely uniaxially oriented amorphous lamellae was produced. The film exhibited enhanced tensile strength with increasing orientation of the lamella. Abstract An amorphous lamellar freestanding film composed of poly(N‐dodecyl acrylamide) (pDDA) was prepared by annealing a micrometer‐thick film under humid conditions (humid ...

Robust β‐myrcene block copolymer elastomeric vitrimers

open access: yesPolymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

Implementation and preliminary evaluation of a practical digital workflow for routine laser‐radiation field coincidence quality assurance on the CyberKnife M6

open access: yesPrecision Radiation Oncology, EarlyView.
An MLC QA tool–QASC–CKQA workflow achieved the lowest laser‐radiation field coincidence deviations on CyberKnife M6, supporting a simpler, more reproducible routine QA strategy. When QASC is unavailable, the film‐based MLC QA tool workflow provides a practical alternative.

Absorption and translocation of 14C‐propiconazole associated with two adjuvants in young coffee plants

open access: yesPest Management Science, EarlyView.
Experimental workflow evaluating 14C‐propiconazole absorption and translocation in Coffea arabica with two biodegradable adjuvants, quantified at six post‐application time points using radioscanner and liquid scintillation spectrometry. Abstract BACKGROUND This study evaluated the absorption, translocation and distribution of 14C‐propiconazole applied ...

Emerging organic X‐ray scintillators enabled by thermally activated delayed fluorescence

open access: yesResponsive Materials, EarlyView.
Thermally activated delayed fluorescence (TADF) X‐ray scintillators are emerging as promising organic radiation‐conversion materials whose absorption, excited‐state dynamics, condensed‐phase organization, and screen architecture jointly govern imaging performance.
