Evolution of Pigments in Artificially Aged Polyethylene Plastics: A Raman Study
Journal of Raman Spectroscopy, EarlyView.The evolution of specific pigments included in plastics exposed to UVA is studied using Raman spectroscopy. This approach is applicable to both organic and inorganic pigments and is facilitated by resonance mechanisms. ABSTRACT The degradation mechanisms of polymers under UV exposure and the evolution of additives are a major concern due to their ...

Grappling with a sea change: Tensions in expert imaginaries of marine carbon dioxide removal
Global Environmental ChangeWhile research on marine carbon dioxide removal (mCDR) expands apace, significant unknowns persist regarding the risks and benefits of individual mCDR options. This paper analyses the assumptions and expectations that animate expert understandings of mCDR, with a focus on issues that are central to the responsible governance of this emerging field of ...

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 ...

Contribution of ultrafine particles to alkalinity in a limestone‐treated waterbody
Limnology and Oceanography: Methods, EarlyView.Abstract While it is well recognized that suspended particles can bias titration‐based total alkalinity (TA), whether addition of minerals for alkalinity enhancement introduces systematic TA artifacts remains poorly quantified. To address this gap, we quantified the contribution of ultrafine particles (< 0.2 μm) to TA titration introduced by limestone (

Quantifying coastal ocean anthropogenic carbon changes and their uncertainties
Limnology and Oceanography: Methods, EarlyView.Abstract Despite recent progress in quantifying anthropogenic carbon (Canth) in global oceans, coastal regions remain understudied due to methodological and observational challenges. Here, we develop and generalize a Regional rEgression–based Coastal Anthropogenic carbon estimation algorithm (RECA) designed specifically for coastal environments ...

Interfacially Engineered Alginate/Hydroxyapatite Biocomposites With High Strength and Toughness
Polymer Composites, EarlyView.Pre‐crosslinking alginate with Ca2+ prior to hydroxyapatite (HAP) formation reduces residual Ca2+ bridging and promotes stronger carboxylate‐hydroxyapatite interfacial interactions, yielding composites with markedly higher strength, stiffness, and toughness than those prepared by the opposite sequence.
