High-Temperature Transport Properties of the Zintl Phases Yb_(11)GaSb_9 and Yb_(11)InSb_9 [PDF]
, 2010 Two rare-earth Zintl phases, Yb_(11)GaSb_9 and Yb_(11)InSb_9, were synthesized in high-temperature self-fluxes of molten Ga and In, respectively. Structures were characterized by both single-crystal X-ray diffraction and powder X-ray diffraction and are ...

A new superconducting open-framework allotrope of silicon at ambient pressure
, 2017 Diamond Si is a semiconductor with an indirect band gap that is the basis of modern semiconductor technology. Although many metastable forms of Si were observed using diamond anvil cells for compression and chemical precursors for synthesis, no metallic ...

K8In10Hg: a Zintl phase with isolated In10Hg clusters [PDF]
Journal of Alloys and Compounds, 1993 Abstract The title compound results from the substitution of one mercury atom for indium in the known metallic K 8 In 11 [8K + + In 11 7− + e − ]. It contains the same isolated eleven-atom clusters as before, pentacapped trigonal prisms compressed along the three-fold axis, but with mercury disordered over the trigonal prismatic sites ( P6 ...

The Zintl-Klemm concept applied to cations in oxides. I. The structures of ternary aluminates [PDF]
, 2003 The structures of 94 ternary aluminates are reinterpreted on the basis of the Zintl-Klemm concept and Pearson's generalized octet rule. In aluminates of highly electropositive metals such as alkali, alkaline-earth and rare-earth metals, the Al atoms form

Isoelectronic Alloying in Zintl Phases Mediated the Avoided Crossing and Phonon Softening
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A small amount of Hf doping endows Zr3Ni3Sb4‐Zintl with an unusually low thermal conductivity far exceeding that of similar systems. Two unique phonon mechanisms—avoided crossing and phonon softening—significantly suppress the lattice thermal conductivity. The average thermoelectric figure of merit is improved by 21%.

Mechanistic Insights of Support Dynamics During Reactive Metal‐Support Interaction
Small Methods, EarlyView.This study uses in situ environmental scanning transmission electron microscopy to investigate the reduction of PdO nanoparticles on ZnO and the formation of intermetallic ZnPd. Hydrogen spillover activates the ZnO support, inducing encapsulation and Zn reduction.
