“…The synthesis of clathrates samples is usually carried out with different methods depending on their dimensions. The fabrication of microscopic samples is usually done by thermal decomposition or solid-state synthesis; the macro samples are produced with well-established routes such as the Czochralski method [89,122] or vertical Bridgman growth [89,123]. Currently, TE applications based on clathrates have not been developed yet, but the studies highlighted that the best performance is achieved in the medium and high temperature range [89,90,121].…”

Solid-state energy conversion has been established as one of the most promising solutions to address the issues related to conventional energy generation. Thermoelectric materials allow direct energy conversion without moving parts and being deprived of greenhouse gases emission, employing lightweight and quiet devices. Current applications, main thermoelectric material classes, and manufacturing methods are the topics of this work; the discussion revolves around the crucial need for highly performing materials in the mid-temperature range, and around the development of more scalable fabrication technologies. The different manufacturing methods for thermoelectric bulk materials and films are also discussed. Small-scale technologies are generating increasing interest in research; the high potential of aerosol jet printing is highlighted, stressing the many advantages of this technology. A promising approach to scale the production of miniaturized thermoelectric devices that combines high energy ball milling and aerosol jet printing is proposed in the conclusion.

“…3.1 Disclosing the effect of oxygen-sulfur exchange on the relevant properties of alkali-metal hexastannates and hexatitanates employing DFT computations Alkali hexatitanates A 2 Ti 6 O 13 , with A = Li + , Na + or K + , exhibit a tunnel structure facilitating the intercalation of alkali-ions. 3,4,[28][29][30][31][32] These compounds can accommodate about three alkali-ions per formula unit in the potential range of 0.9-1.5 V. 3,4,[28][29][30][31][32] Sulfurcontaining compounds have been shown to have better ionic conductors and deformability. 11,21,22 Taking advantage of both sulfur-containing compounds and A 2 Ti 6 O 13 tunneled structures, we explored relevant properties of A 2 B 6 X 13 with A = Li + , Na + or K + ; B = Ti 4+ or Sn 4+ and X = O 2À or S 2À compounds.…”

“…29,30 Various synthesis methods have been designed for doping and tuning the charge carrier concentration in the sample. [30][31][32][33] A majority of these experimental methods are rather expensive, especially for research groups from developing countries. Therefore, advanced atomistic simulations can help the experimentalists to select appropriate dopants to improve a particular property, alleviating negative effects.…”

The Czochralski (CZ) growth technique is widely applied in crystal growth, using both induction and resistance heaters. In this work, a novel model experiment platform with comprehensive in-situ measurement capability is introduced. Growth experiments with the model material tin applying both heating concepts are performed and analyzed, e.g., in terms of the maximum achievable crystal diameter. Strong asymmetries in the magnetic field of the induction heater are measured and temperature distribution on the resistance heater is found to be non-uniform. Furthermore, significant losses are observed in the power supplies of the resistance heater. The heating efficiency of both concepts is compared considering different insulation geometries. The obtained results show the capability of model experiments for design optimization and will provide valuable input for further validation of numerical simulations.
