Assessing the Effect of Large Igneous Provinces on Global Oceanic Redox Conditions Using Non‐traditional Metal Isotopes (Molybdenum, Uranium, Thallium)

open access: yesGeophysical Monograph Series, Page 305-323., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Design of Aerosol Coating Reactors: Precursor Injection [PDF]

open access: yesIndustrial & Engineering Chemistry Research, 2011
Particles are coated with thin shells to facilitate their processing and incorporation into liquid or solid matrixes without altering core particle properties (coloristic, magnetic, etc.). Here, computational fluid and particle dynamics are combined to investigate the geometry of an aerosol reactor for continuous coating of freshly-made titanium ...

Profiling structured beams using injected aerosols [PDF]

open access: yesSPIE Proceedings, 2012
Profiling structured beams produced by X-ray free-electron lasers (FELs) is crucial to both maximizing signal intensity for weakly scattering targets and interpreting their scattering patterns. Earlier ablative imprint studies describe how to infer the X-ray beam profile from the damage that an attenuated beam inflicts on a substrate.

Changing transport processes in the stratosphere by radiative heating of sulfate aerosols [PDF]

open access: yesAtmospheric Chemistry and Physics, 2017
The injection of sulfur dioxide (SO2) into the stratosphere to form an artificial stratospheric aerosol layer is discussed as an option for solar radiation management.

Smoke injection heights from agricultural burning in Eastern Europe as seen by CALIPSO [PDF]

open access: yesAtmospheric Chemistry and Physics, 2010
High frequency of agricultural fires is observed every year during the summer months over SW Russia and Eastern Europe. This study investigates the initial injection height of aerosol generated by the fires over these regions during the biomass burning ...

The effects of timing and rate of marine cloud brightening aerosol injection on albedo changes during the diurnal cycle of marine stratocumulus clouds [PDF]

open access: yesAtmospheric Chemistry and Physics, 2013
The marine-cloud brightening geoengineering technique has been suggested as a possible means of counteracting the positive radiative forcing associated with anthropogenic atmospheric CO<sub>2</sub> increases.

Dynamical Perturbation of the Stratosphere by a Pyrocumulonimbus Injection of Carbonaceous Aerosols

open access: yesAtmospheric Chemistry and Physics, 2022
Abstract. The Pacific Northwest pyrocumulonimbus Event (PNE) took place in British Columbia during the nighttime hours between the 12th and 13th of August 2017. Several pyroconvective clouds erupted in this occasion, and released in the upper troposphere/lower stratosphere unprecedented amounts of carbonaceous aerosols (300 ktn). Only a few years later,

A Subpolar-focused Stratospheric Aerosol Injection Deployment Scenario

open access: yesEnvironmental Research Communications, 2022
Abstract Stratospheric aerosol injection (SAI) is a prospective climate intervention technology that would seek to abate climate change by deflecting back into space a small fraction of the incoming solar radiation. While most consideration given to SAI assumes a global intervention, this paper considers an alternative scenario whereby SAI ...

The sensitivity of CO and aerosol transport to the temporal and vertical distribution of North American boreal fire emissions [PDF]

open access: yesAtmospheric Chemistry and Physics, 2009
Forest fires in Alaska and western Canada represent important sources of aerosols and trace gases in North America. Among the largest uncertainties when modeling forest fire effects are the timing and injection height of biomass burning emissions.

Numerical simulation on aerosol pool scrubbing [PDF]

open access: yesE3S Web of Conferences, 2020
In the event of severe accident for nuclear power plant (NPP), radioactive aerosols may be released into spent fuel pool (SFP) through filtered-containment-venting-system (FCVS), which are entrained by mixing gas from containment, in order to prevent the
