The Zintl-Klemm Concept in the Amorphous State: A Case Study of Na-P Battery Anodes. [PDF]
Angew Chem Int Ed EnglThe long‐established Zintl–Klemm concept can be applied to amorphous materials just as well — as is shown here for disordered Na–P phases that are relevant for sodium‐ion battery anodes. Machine‐learning‐driven, quantum‐mechanically accurate simulations yiel insights into structure and bonding, and unlock the atomistic modeling of structural changes ...

Improved figure of merit (z) at low temperatures for superior thermoelectric cooling in Mg3(Bi,Sb)2
Nature Communications, 2023 The low-temperature thermoelectric performance of Bi-rich n-type Mg3(Bi,Sb)2 was limited by the electron transport scattering at grain boundaries, while removing grain boundaries and bulk crystal growth of Mg-based Zintl phases are challenging due to the

Ag<sub>12</sub>[Ge<sub>9</sub>(Hyp)<sub>2</sub>]<sub>6</sub> An Intermetalloid Cluster with Bis-Silylated Ge<sub>9</sub> Units. [PDF]
Angew Chem Int Ed EnglThe reaction of K2Ge9(Hyp)2 (Hyp = Si(SiMe3)3) with phosphine stabilized silver halides gives the new intermetalloid cluster Ag12[Ge9(Hyp)2]6 exhibiting a novel Ag12 core surrounded by six [Ge9(Hyp)2] units acting as ligands. Within the Ag12 core two different kinds of silver atoms are present underlining the intermetalloid character of the cluster ...
