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.,

Bioacumulació de 210Po a nivell subcel·lular

, 2012
S’ha analitzat la concentració de 210Po en les fraccions subcel·lulars en òrgans digestius per diferents espècies de peixos. S’ha determinat que al voltant d'un 50% del 210Po es concentra en la fracció de citoplasma. La fracció de citoplasma es va separar en diferents especiacions químiques on es va determinar que la fracció de proteïna era la més ...

Activity Levels of Polonium-210 in Tobacco and Cigarette in Iran [PDF]

مجله علوم و فنون هسته‌ای, 2011
Polonium-210 (210Po) is a natural contaminant of tobacco and its products. Due to its volatility and inherent adsorption properties, 210Po is one of the major potential sources of human exposure through smoking.

Nuclear data uncertainty analysis for the Po-210 production in MYRRHA

EPJ Nuclear Sciences & Technologies, 2018
MYRRHA is a multi-purpose research reactor able to operate in sub-critical and critical modes and currently in the design phase at SCK•CEN. The choice of LBE was driven by its chemical stability, low melting temperature, high boiling point, low chemical ...

Bremsstrahlung radiation by a tunneling particle

, 1998
We study the bremsstrahlung radiation of a tunneling charged particle in a time-dependent picture. In particular, we treat the case of bremsstrahlung during alpha-decay, which has been suggested as a promissing tool to investigate the problem of ...

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 ...
