Single-layer cluster ionic-chain networks with tetragonal pores

Nature Communications
Two-dimensional (2D) materials with intrinsic pores have attracted attention for catalytic and electronic applications. However, a significant gap exists between all-inorganic 2D networks with inorganic connectors and those with organic connectors due to

Origin of Low-Lying Enhanced E1 Strength in Rare-Earth Nuclei

, 2015
The experimental $E1$ strength distribution below 4 MeV in rare-earth nuclei suggests a local breaking of isospin symmetry. In addition to the octupole states, additional $1^-$ states with enhanced E1 strength have been observed in rare-earth nuclei by ...

Anisotropic Wear Resistance of Heat-Treated Selective Laser-Melted 316L Stainless Steel

Lubricants
Anisotropic microstructures and wear resistance are caused by large thermal gradients during selective laser melting (SLM). Investigating the wear resistance in different planes of SLM specimens is crucial.

Theory of long range interactions for Rydberg states attached to hyperfine split cores

, 2017
The theory is developed for one and two atom interactions when the atom has a Rydberg electron attached to a hyperfine split core state. This situation is relevant for some of the rare earth and alkaline earth atoms that have been proposed for ...

The Effect of $f$-$d$ Magnetic Coupling in Multiferroic $R$MnO$_3$ Crystals

, 2010
We have established detailed magnetoelectric phase diagrams of (Eu$_{0.595}$Y$_{0.405}$)$_{1-x}$Tb$_x$MnO$_3$ ($0 \le x \le 1$) and (Eu,Y)$_{1-x}$Gd$_x$MnO$_3$ ($0 \le x \le 0.69$), whose average ionic radii of $R$-site ($R$: rare earth) cations are ...
