Application of Gas‐Phase Electrophoresis (nES GEMMA Instrumentation) in Molecular Weight Determination

Journal of Mass Spectrometry, Volume 60, Issue 11, November 2025.
ABSTRACT Gas‐phase electrophoresis by means of a nano‐Electrospray Gas‐phase Electrophoretic Mobility Molecular Analyzer (nES GEMMA, also known as e.g., nES DMA, MacroIMS, or LiquiScan ES) separates singly charged, aerosolized (bio‐)nanoparticles at ambient pressure in the gas phase according to the particle electrophoretic mobility (EM) diameter, i.e.,

Contrasting Effects of Road Dust and Atmospheric Dust on Carbon Accumulation in Eastern Canadian Ombrotrophic Peatlands

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 8, August 2025.
Abstract Limited research has been conducted on the role of atmospheric dust as a nutrient source for peatlands, and none has studied the effects of localized and intense road dust on peatland carbon (C) accumulation. To compare the effects of dust deposition from these two sources on peatlands, we examined three ombrotrophic peatlands adjacent to ...

Hydroclimate variability in the eastern Kimberley, Australia, since the last deglaciation

Journal of Quaternary Science, Volume 40, Issue 5, Page 893-912, July 2025.
ABSTRACT The climate of the Kimberley region in tropical northwest Australia is dominated by the Indo‐Australian summer monsoon (IASM). Understanding of the palaeoclimate since the Last Glacial Maximum in this region, which is well placed to record IASM variations, is currently based on few records.

Particle Export Fluxes in the Southern Ocean: Importance of Nonheterotrophic Processes in POC Flux Attenuation

Journal of Geophysical Research: Oceans, Volume 130, Issue 7, July 2025.
Abstract The ocean contributes to regulating atmospheric CO2 levels via the biological carbon pump (BCP). One critical aspect of the BCP is the depth at which sinking particulate organic carbon (POC) remineralizes in the mesopelagic zone (200–1,000 m). In the Southern Ocean, the circulation is such that the products generated from POC remineralization ...

Preparation of Standard Plane Source of 210Po

Journal of Isotopes, 2021
A method of spontaneous deposition of 210Po on a silver disc was used to prepare the standard plane source in a 210Pb solution. The prepared source was measured by an alpha spectrometer.

Nitrogen Processes Within Tropical Mangroves in Australia

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 4, April 2025.
Abstract Coastal wetlands have long been identified as ecosystems that can ameliorate N inputs into the ocean. The processes associated with N uptake, transformation, and losses are relatively well understood for temperate wetlands; however, information on tropical wetlands is scarce.
