Methane exchange at the peatland forest floor – automatic chamber system exposes the dynamics of small fluxes [PDF]

open access: yesBiogeosciences, 2017
We measured methane (CH4) exchange rates with automatic chambers at the forest floor of a nutrient-rich drained peatland in 2011–2013. The fen, located in southern Finland, was drained for forestry in 1969 and the tree stand is now a mixture of Scots ...

Characterization of trace metals on soot aerosol particles with the SP-AMS: detection and quantification [PDF]

open access: yesAtmospheric Measurement Techniques, 2015
A method to detect and quantify mass concentrations of trace metals on soot particles by the Aerodyne soot-particle aerosol mass spectrometer (SP-AMS) was developed and evaluated in this study.

The ubiquitin ligase RNF115 is required for the clearance of damaged lysosomes

open access: yesFEBS Letters, EarlyView.
Upon lysosomal rupture, an E3 ubiquitin ligase RNF115 translocates from the cytosol to the damaged lysosomal membrane. Moreover, RNF115 depletion impairs the clearance of damaged lysosomes, identifying it as a key regulator of lysosomal quality control.

Measurement report: The effects of SECA regulations on the atmospheric SO2 concentrations in the Baltic Sea, based on long-term observations on the Finnish island, Utö [PDF]

open access: yesAtmospheric Chemistry and Physics
The designation of the Baltic Sea as a sulfur emission control area (SECA) in May 2006, with subsequent tightening of regulations in 2010 and 2015, has reduced the sulfuric emission from shipping traffic.

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

The applicability and challenges of black carbon sensors in monitoring networks [PDF]

open access: yesAerosol Research
Black carbon (BC) is a particulate pollutant emitted as a by-product of combustion. BC has an emerging role in air quality monitoring with the current recommendations by the World Health Organization to monitor BC to capture its temporal and spatial ...

Snow Samples Combined With Long-Range Transport Modeling to Reveal the Origin and Temporal Variability of Black Carbon in Seasonal Snow in Sodankylä (67°N)

open access: yesFrontiers in Earth Science, 2020
In the Arctic areas, the influence of global climate change is enhanced. Enabling a better understanding of the changes in the Arctic environment is of the utmost importance.

The Composition of the Atmosphere [PDF]

open access: yesNature, 1914
MR. A. PARKER (Jour. Chem. Soc., April, 1914) in a study of the inflammation of mixtures of methane with oxygen and nitrogen, has found that inflammation can be brought about more easily in mixtures containing nitrogen than in pure oxygen. In fact, the mixture which requires for ignition a minimum of methane contains only about 23 per cent.

Composition of Titan's Atmosphere [PDF]

open access: yes, 2021
As a result of the 13-year exploration of the Saturn system by the Cassini-Huygens mission (2004–17), there has been a revolution in our understanding of Titan, Saturn's largest satellite. Titan's atmosphere shows the most complex chemistry in the solar system.
