Intercomparison of carbon‐13 and carbon‐14 tracer approaches for estimating marine calcification and net primary production

Limnology and Oceanography: Methods, EarlyView.
Abstract Accurate measurements of phytoplankton net primary production (NPP) and calcification are essential for quantifying marine carbon cycling, yet in situ calcification rates remain poorly constrained. We compared 13C‐ and 14C‐based tracer methods for NPP in laboratory cultures of the diatom Chaetoceros tenuissimus and the coccolithophore ...

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

Polymer 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,

Robust β‐myrcene block copolymer elastomeric vitrimers

Polymer 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 ...
