Timing of Dike and Sill Emplacement in the Inner Aureole of the Alta Stock, Utah Determined by Zircon and Monazite Petrochronology

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 5, May 2025.
Abstract Detailed geochronology from two compositionally distinct generations of dikes and sills intruded into the Alta metamorphic aureole, north‐central Utah, complement previous geochronologic studies from the Alta stock, providing information on the timing of magmatism and the nature of emplacement.

REE fractionation during granite weathering and removal by waters and suspended loads: Sr and Nd isotopic evidence [PDF]

, 2001
Very few studies deal with REE (rare earth element) mobility within the system soil–soil solution–streamwater. In this article, we try to characterize the fractionation and the migration of the REE in a granite-derived soil system located in a small ...

Insights From Megacryst‐Included Zircon Dates on the Spatial Extent of Magma Mixing in the Tuolumne Intrusive Suite, California, USA

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 5, May 2025.
Abstract The spatial extent of mixing between separately emplaced batches of magma is a key component in understanding the incremental assembly of plutons. Potassium feldspar megacrysts (>3 cm length) in granodioritic rocks are hypothesized to record magma mixing and transport over hundred kyr timescales.

Effects of Phosphorus Deficiency on Leaf Surface Morphology: Absorption and Translocation of Foliar‐Applied Phosphorus in Four Barley Cultivars

Physiologia Plantarum, Volume 177, Issue 3, May/June 2025.
ABSTRACT Plant nutrient deficiencies can modify leaf surface properties and may affect the absorption of foliar fertilisers. This study examined how plant P‐deficiency modified the adaxial leaf surface morphology of four barley cultivars and whether these modifications could be linked to quantitative differences in foliar‐applied P absorption.

Generation of Site‐Specifically Labeled Affinity Reagents via Use of a Self‐Labeling Single Domain Antibody

Advanced Science, Volume 12, Issue 14, April 10, 2025.
Several methods have been used to label antibodies to facilitate visualization of cognate targets. Here, we leverage a new variety of conjugation chemistry, based on a crosslinking nanobody, to label target‐specific nanobody constructs with functionalities of choice.

Note on the reflectance of mirrors exposed to a strontium beam [PDF]

arXiv, 2018
The high chemical reactivity of strontium, which can opacify a viewport exposed to a strontium atomic source, is a concern for some atomic physics experiments where it is sometimes necessary to send a laser beam counter-propagating relative to the atomic beam.

Collinear laser spectroscopy of radioisotopes of zirconium [PDF]

, 2003
Isotope shifts and hyperfine structures have been measured for radioisotopes of ionic zirconium using on-line laser spectroscopy at the IGISOL facility in Jyväskylä, where the installation of an ion beam cooler/buncher has significantly improved the ...

Technetium ‐ The Unknown Center of the Periodic Table

European Journal of Inorganic Chemistry, Volume 28, Issue 9, March 21, 2025.
It took 78 years from Mendeleev's proposal of an existence of “eka‐manganese” (1869) until it was finally named as technetium in 1947. Another 78 years have passed since then. A good occasion to pinpoint what we know and what we still don't know of this element in the center of the periodic table.

Nuclear Criticality, Shielding, and Thermal Analyses of Separations Processes for the Transmutation Fuel Cycle

, 2004
The first step in any transmutation strategy is the separation of radionuclides in used nuclear fuel. The current separation strategy supporting the Advanced Fuel Cycle Initiative (AFCI) program is based on the use of a solvent extraction separation ...
