Production, Biodegradation,and Recalcitrance of OrganicCarbon from Cultivated Saccharina latissima in Norway

Abstract Particulate (POC) and dissolved (DOC) organic carbon released during macroalgae cultivation has been shown to lead to carbon burial and export to the open ocean and deep sea. The recalcitrant portion of the DOC (RDOC) is a critical contributor to carbon sequestration and...

Time-resolved imaging of antiferromagnetic skyrmion interactions

Abstract Quantifying particle interactions is central to understanding and controlling collective dynamics in particle-based devices such as those comprising skyrmion ensembles. Here we directly visualize, in real time, the nanosecond current-driven dynamics of an antiferromagnet...

7 Tesla MRI with Quantitative Susceptibility Mapping: qualitative grading and quantitative focal measurements of the substantia nigra as a potential biomarker for Parkinson’s disease

PURPOSE: Parkinson's disease (PD) is characterized by dopaminergic neuronal loss in the substantia nigra (SN). Imaging biomarkers sensitive to nigral pathology are limited. This study evaluated susceptibility changes in the SN using quantitative susceptibility mapping (QSM) and s...

Fabrication and performance evaluation of TiO2 nanoparticle modified cellulose/PBS biocomposites

Abstract In this study, jute fiber cellulose (JFC) was extracted from raw jute fibers using an alkaline (NaOH + H 2 O 2 ) chemical treatment. Titanium dioxide (TiO 2 ) nanoparticle-dispersed cellulosic biocomposite films (JFC-TiO 2 ) were subsequently fabricated and coated with b...

Tuning electron back-donation to switch reaction pathway in CO2 hydrogenation

CO2 hydrogenation over earth-abundant Ni catalysts is attractive for CO-based fuel synthesis, but Ni intrinsically favors methanation. Here we show that ordered Ni3Sn2 intermetallics tune Ni–CO electron back-donation and switch CO2 hydrogenation from CH4 formation to the reverse...

Extinction Prediction and Emission Analysis of a Bluff-Body Stabilized Ammonia-Hydrogen-Nitrogen Premixed Flame With Conjugate Heat Transfer

Abstract Ammonia/hydrogen blends represent a promising carbon-free fuel for gas turbine combustors. To minimize the NOx emission, premixed ammonia/hydrogen/nitrogen flames under ultra lean equivalence ratios are investigated. This paper simulates the extinction process of a bluff...

Effects of maternal and paternal smoking on offspring cardiometabolic risk factors in adulthood: a multi-method intergenerational Mendelian randomization study

Abstract Background Parental smoking has been linked to several adverse offspring cardiometabolic outcomes; however, evidence is conflicting regarding the causal and long-term nature of these associations. Methods We investigated the effects of maternal and paternal smoking, capt...
