In‐situ asphaltene capture with iron oxide nanoparticles in steam‐assisted gravity drainage (SAGD) for improved recovery and partial upgrading of bitumen

The Canadian Journal of Chemical Engineering, EarlyView.
Key improvements obtained by incorporating nanoparticles into a lab‐scale SAGD process configuration. The bar plots show enhanced oil recovery, reduced viscosity, and increased asphaltene adsorption in nanoparticle‐assisted scenarios compared with conventional SAGD.

A Novel Neutral Polysaccharide From Bamboo Shoot Processing Liquid: Structural Characterization and In Vitro TLR4/NF‐κB Mediated Anti‐Inflammatory Activity

Food Bioengineering, EarlyView.
ABSTRACT Value‐added utilization of resources can be developed from by‐products of agricultural processing. In this study, a neutral polysaccharide (BSLP‐1, 19,799 Da) was obtained from bamboo shoot processing liquid. Structurally, BSLP‐1 has a backbone of →4)‐α‐D‐Glcp‐(1→ and →4,6)‐α‐D‐Glcp‐(1→, with side chains of →5)‐α‐L‐Araf‐(1→ and α‐D‐Glcp‐(1→6 ...

The cooling rate of neutron stars after thermonuclear shell flashes [PDF]

, 2013
Thermonuclear shell flashes on neutron stars are detected as bright X-ray bursts. Traditionally, their decay is modeled with an exponential function. However, this is not what theory predicts.
