Spanning the Periodic Table: Select examples of stable isotope target fabrication at Oak Ridge National Laboratory [PDF]

EPJ Web of Conferences, 2023
This paper reviews select examples of recent targets produced by the group, including 171Yb wires, 62Ni pellets, and 25Mg foils. The targets discussed will cover the processes and equipment used for stable isotope manufacturing at ORNL and give a broader

Spherical powders: Control over the size and morphology of powders for additive manufacturing and enriched stable isotope nuclear targets [PDF]

EPJ Web of Conferences, 2023
Metal powders are a fundamental starting point for fabricating many types of nuclear targets. Elemental powder properties can differ drastically between batches, even when using the same method.

Development of low-loss minimal exposure technique for thallium foil fabrication [PDF]

EPJ Web of Conferences, 2023
Despite its availability as a solid bead or ingot, non-isotopic thallium metal is no longer commercially produced as a foil because of its high toxicity.

Chemical and isotopic characterization of the thermal fluids emerging along the North–Northeastern Greece

Scientific Reports, 2021
Hydrochemical and isotopic characteristics of fluids from major geothermal fields of middle/low temperature in N/NE Greece are examined [basins: Strymon River (SR), Nestos River Delta (ND), Xanthi–Komotini (XK), Loutros–Feres–Soufli (LFS) and Rhodope ...

Sulphur isotope stratigraphy of drill cuttings and stratigraphic correlation of Permian-Triassic evaporites

Frontiers in Earth Science, 2023
The stratigraphy of the European late Permian-Triassic commonly lacks chronostratigraphic constraint due to the scarcity of diagnostic fossils for biostratigraphy.

Accurate Quantification of β-Lactoglobulin in Bovine Milk by HPLC-IDMS [PDF]

Zhipu Xuebao, 2023
Milk is one of the most common and widespread allergenic foods. Milk allergy is an adverse immunological reaction to milk proteins of different mammalian species. β-Lactoglobulin (β-LG) is one of the main allergenic proteins of cow's milk.

Direct O₂ control on the partitioning between denitrification and dissimilatory nitrate reduction to ammonium in lake sediments [PDF]

Biogeosciences, 2019
Lacustrine sediments are important sites of fixed-nitrogen (N) elimination through the reduction of nitrate to N2 by denitrifying bacteria, and they are thus critical for the mitigation of anthropogenic loading of fixed N in lakes.

Phytoplankton Fuel Fish Food Webs in a Low-Turbidity Temperate Coastal Embayment: A Stable Isotope Approach

Frontiers in Marine Science, 2021
Trophic contributions of diverse OM sources to estuarine and coastal food webs differ substantially across systems around the world, particularly for nekton (fish, cephalopods, and crustaceans), which utilize basal resources from multiple sources over ...
