Modeling of 2008 Kasatochi volcanic sulfate direct radiative forcing: assimilation of OMI SO₂ plume height data and comparison with MODIS and CALIOP observations [PDF]

Atmospheric Chemistry and Physics, 2013
Volcanic SO2 column amount and injection height retrieved from the Ozone Monitoring Instrument (OMI) with the Extended Iterative Spectral Fitting (EISF) technique are used to initialize a global chemistry transport model (GEOS-Chem) to simulate the ...

Evidence for volcanic forcing of Holocene cold events

Nature Communications
Abstract During the Holocene, the climatic stability of the northern hemisphere was intermittently disrupted by centennial-scale cooling events, whose origins remain unclear. Explosive volcanism is a plausible trigger, yet its potential to drive longer-term (centennial-to-millennial) perturbations remains underexplored.

Designing Vanadium‐Based Oxide Electrocatalysts for Water Splitting: Experimental and Mechanistic Insights with Machine Learning

Advanced Functional Materials, EarlyView.
This review establishes structure‐property‐mechanism relationships across six modification strategies for V‐based oxide water‐splitting electrocatalysts: lattice engineering, heteroatom doping, interface engineering, carbon‐based hybridization, morphology engineering, and surface reconstruction and pre‐catalyst design, where dissolution is reframed as ...

Peatlands, volcanoes and climate: Ecological and palaeoecological studies in Alaska and Scotland [PDF]

, 2005
PhDThis thesis investigates direct and indirect volcanic impacts on peatlands using palaeoecological and ecological techniques. The primary approach used is palaeoecological studies across tephra layers. A multi-proxy methodology was adopted including

A timescale analysis of the Northern Hemisphere temperature response to volcanic and solar forcing [PDF]

Climate of the Past, 2005
The Northern Hemisphere temperature response to volcanic and solar forcing in the time interval 1000–1850 AD is studied using first a set of simulations with an intermediate-complexity climate model, driven by reconstructed forcings.

Statistical framework for evaluation of climate model simulations by use of climate proxy data from the last millennium – Part 3: Practical considerations, relaxed assumptions, and using tree-ring data to address the amplitude of solar forcing [PDF]

Climate of the Past, 2015
A statistical framework for evaluation of climate model simulations by comparison with climate observations from instrumental and proxy data (part 1 in this series) is improved by the relaxation of two assumptions.

A Magneto‐Mechanically Activated Nerve Guidance Conduit Promotes Peripheral Nerve Regeneration via TIMP1‐Mediated Membrane Tension Transfer

Advanced Functional Materials, EarlyView.
This study presents a magneto‐mechanical strategy that incorporates FP@MSCs into an aligned PCL/GelMA nerve guidance conduit. Magnetic stimulation increases membrane tension in FP@MSCs, triggering cytoskeletal remodeling, Schwann cell‐like differentiation, and TIMP1 secretion. TIMP1 activates ITGB1/CD63–FAK signaling in NE‐4C cells, increasing membrane

Influence of future air pollution mitigation strategies on total aerosol radiative forcing [PDF]

, 2008
We apply different aerosol and aerosol precursor emission scenarios reflecting possible future control strategies for air pollution in the ECHAM5-HAM model, and simulate the resulting effect on the Earth's radiation budget.
