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.

Proteomic profiling of Elp1‐deficient trigeminal ganglia reveals disruption of neurotrophic and metabolic pathways in a familial dysautonomia mouse model

Developmental Dynamics, EarlyView.
Abstract Background Elp1, a subunit of the Elongator complex, is essential for tRNA modification and neuronal development. Mutations in ELP1 underlie familial dysautonomia (FD), a disorder marked by sensory and autonomic neuropathy. While loss of Elp1 disrupts trigeminal ganglion formation and survival, the downstream molecular consequences remain ...

Research Journal of Pharmacy and Technology, 2016
Laser Induced Breakdown Spectroscopy (LIBS) is an atomic emission spectroscopy technique for a rapid chemical analysis of different type of analytes like solids, liquids and gases. LIBS can often be referred to as its alternative name: laser-induced plasma spectroscopy (LIPS).

Laser induced breakdown spectroscopy on meteorites

Spectrochimica Acta Part B: Atomic Spectroscopy, 2007
The classification of meteorites when geological analysis is unfeasible is generally made by the spectral line emission ratio of some characteristic elements. Indeed when a meteorite impacts Earth's atmosphere, hot plasma is generated, as a consequence of the braking effect of air, with the consequent ablation of the falling body.

Laser-Induced Breakdown Spectroscopy

2015
Abstract Laser-induced breakdown spectroscopy (LIBS) represents a useful analytical tool for elemental analysis of solid or liquid materials. An intense pulsed laser can be employed, focused on the surface of the material, to ignite a spark and generate a plume of gaseous atoms and molecules in a distribution of excited states.
