Airborne soil organic particles generated by precipitation [PDF]

Nature Geoscience, 2016
Airborne organic particles affect Earth’s climate. Imaging of particles after rain events and experimental irrigation shows that water drop impaction of soils generates solid organic particles, with impacts on clouds and radiation absorption.

Investigation of nucleation and crystal growth kinetics of nickel manganese oxalates [PDF]

, 2005
The nucleation and the crystal growth rates of mixed nickel manganese oxalates have been determined from the changes of the ionic concentration of the solution and the crystal size distribution during the precipitation process within a supersaturation ...

Indirect determination of the energy spectra of particles precipitated in the lower ionosphere associated with solar proton events [PDF]

Geofísica Internacional, 2000
Electron density profiles previously measured using the phase and amplitude of VLF radio signals during outstanding solar proton events (SPE), together with the associated energy spectra of protons and electrons simultaneously measured by satellite ...

Oxidation-assisted alkaline precipitation : the effect of H2O2 on the size of CuO and FeOOH nanoparticles [PDF]

, 2019
H2O2 was demonstrated to narrow the size distribution and decrease the size of CuO and hydrous FeOOH (2-line ferrihydrite) nanoparticles under conditions of high supersaturation.

A CRITICAL REVIEW OF MODELS USED IN NUMERICAL SIMULATION OF ELECTROSTATIC PRECIPITATORS

Informatyka, Automatyka, Pomiary w Gospodarce i Ochronie Środowiska, 2016
The electrostatic precipitators (ESP) have been drawing more and more attention due to their high efficiency and low costs. Numerical simulation is a powerful, economical and flexible tool to design ESP for industry applications.

Ion Inverted‐V Precipitation Adjoining Auroral Arc: Low‐Altitude Observations With High Time/Space Resolution by the Reimei Microsatellite

Geophysical Research Letters
Previous studies have verified that upward geomagnetic field‐aligned electric fields (FAEFs) produce inverted‐V signatures of precipitating electrons that generate discrete auroras in upward field‐aligned currents (FACs).

Quantifying wet scavenging processes in aircraft observations of nitric acid and cloud condensation nuclei [PDF]

, 2006
Wet scavenging is an important sink term for many atmospheric constituents. However, production of precipitation in clouds is poorly understood, and pollutant removal through wet scavenging is difficult to separate from removal through dry scavenging ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library

FEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Observations of three-dimensional ionospheric plasma properties in a space hurricane

Frontiers in Astronomy and Space Sciences
The space hurricane is a newly discovered large-scale three-dimensional magnetic vortex structure that spans the polar ionosphere and magnetosphere.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.
