Partitioning of Ca to metastable precipitates in a Mg-rare earth alloy

Materials Research Letters, 2023
The potential effect of the element Ca on the precipitation behavior was investigated in an Mg-rare earth alloy. A combination of metastable β′′′ and β′ precipitates was observed for the peak aging condition at 200°C.

Optical spectroscopy study on CeTe$_3$: evidence for multiple charge-density-wave orders

, 2010
We performed optical spectroscopy measurement on single crystal of CeTe$_3$, a rare-earth element tri-telluride charge density wave (CDW) compound. The optical spectra are found to display very strong temperature dependence.

Lanthanum(III) triggers AtrbohD- and jasmonic acid-dependent systemic endocytosis in plants

Nature Communications, 2021
Rare earth elements are widely used in agriculture to promote plant growth. Here the authors show that aerial application of a rare earth element to the leaves triggers a graft-transmissible, RbohD- and jasmonic acid-dependent systemic signal that ...

Coupling of a locally implanted rare-earth ion ensemble to a superconducting micro-resonator

, 2014
We demonstrate the coupling of rare-earth ions locally implanted in a substrate (Gd$^{3+}$ in Al$_{2}$O$_{3}$) to a superconducting NbN lumped-element micro-resonator. The hybrid device is fabricated by a controlled ion implantation of rare-earth ions in
