Abstract

Structure and property investigations of the Zintl phases Eu14AlAs11 and Eu14AlSb11: magnetism, electrical resistivity, Mössbauer spectroscopy and theoretical calculations.

Structural, Physical, Theoretical and Spectroscopic Investigations of Mixed‐Valent Eu2Ni8Si3 and Its Structural Anti‐Type Sr2Pt3Al8

“…Furthermore, a correlation of the electric field gradient (78 K: Δ E Q (Eu 2+ )=6.8(1) mm s −1 ; 6 K: (Δ E Q (Eu 3+ )=−0.7(3) mm s −1 ) and the line width is possible. Such a scenario usually arises near the magnetic ordering temperature and can be fitted using a distribution of magnetic hyperfine fields, as shown for the Eu‐containing Zintl ‐phases Eu 5 In 2 Pn 6 ( Pn =As, Sb) [70] and Eu 14 Al Pn 11 ( Pn =As, Sb) [71] …”

(Pseudo)binary Antimonides: Insights on Local Ordering and Effective Charge Configurations from 121Sb MAS NMR and Mössbauer Spectroscopies

“…Although the 121 Sb nucleus is not that widely used, ionic compounds of Sb III and Sb V especially have been studied. , Turning to intermetallic antimony compounds, the number of well-characterized phases is small. Early studies focused on the III–V semiconductors AlSb, GaSb, and InSb (sphalerite type); , some of the rare-earth (RE) monoantimonides; rare-earth–transition-metal–antimonides; − and a number of intermetallic, antimony-based battery materials. − The first systematization efforts were performed during studies of the latter materials’ class. , …”

The Ampoule Method: A Pathway towards Controllable Synthesis of Electrocatalysts for Water Electrolysis

“…The ampoule method can be conducted over a wide temperature range, including low (≤ 300 °C), [26,27] mild (300-900 °C) [28,29] and high temperatures (≥ 1000 °C). [30,31] Furnaces with heterogeneous or homogeneous temperature can be applied. For the former configuration, isothermal hot and cold regions are formed and separated by an adiabatic zone (Figure 3a left), or a linear temperature profile is established by tapered heating (Figure 3a right).…”

“…Afterwards, its open end is thermally melted and sealed. The ampoule method can be conducted over a wide temperature range, including low (≤300 °C), mild (300–900 °C), and high temperatures (≥1000 °C) . Furnaces with hetero‐ or homogeneous temperature can be applied.…”
