The 55Fe half-life measured with a pressurised proportional counter

Applied Radiation and Isotopes, 2019
The half-life of 55Fe has been measured accurately by following the decay curve of three sources with a large pressurised proportional counter. An argon(90%)-methane(10%) mixture was used as counter gas, at atmospheric pressure (∼1 × 105 Pa) and at enhanced pressures of 5 × 105 Pa and 8 × 105 Pa (for 1 source), respectively. The first measurements were

Tightly coupled carbon, nitrogen, and iron utilization by bacteria in the lower photic zone of the North Pacific Subtropical Gyre

Limnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract The metabolism of heterotrophic bacteria acts as a key control on the turnover of organic matter in the ocean. However, much remains unknown about how nutrient availability, particularly iron concentration, impacts bacterial growth. In the dimly lit waters of the lower photic and upper mesopelagic zones, the attenuation of sinking particulate ...

Regulation of iron-siderophore uptake in a diazotrophic cyanobacterium Anabaena anabaena 7120

The Indian Journal of Agricultural Sciences, 2014
The regulation of 55Fe-siderophore uptake of was studied in a diazotrophic cyanobacterium Anabaena 7120. The uptake up to 20 min was found to be biphasic, a rapid first and steady second phase.
