Stability Issues

<div> <div> <div> <p>Metal nanoparticles (NPs) are usually stabilized by a capping agent, a surfactant, or a support material, to maintain their integrity. However, these strategies can impact their intrinsic catalytic activity. Here, we demonstrate that the in-situ formation of copper NPs (Cu0NPs) upon the reduction of the earth-abundant Jacquesdietrichite mineral with ammonia borane (NH3BH3, AB) can provide an alternative solution for stability issues. During the formation of Cu0NPs, hydrogen gas is released from AB, and utilized for the reduction of nitroarenes to their corresponding anilines, at room temperature and under ambient pressure. After the nitroarene-to-aniline conversion is completed, regeneration of the mineral occurs upon the exposure of Cu0NPs to air. Thus, the hydrogenation reaction can be performed multiple times without the loss of the Cu0NPs’ activity. As a proof-of-concept, the hydrogenation of drug molecules “flutamide” and “nimesulide” was also performed and isolated their corresponding amino-compounds in high selectivity and yield. </p> </div> </div> </div>

Global warming is the driving force for developing new functional thermoelectric generators based on new materials which contain at least one of the elements Si, Se, or Sn. We describe four processing methods and their characterization by SEM and thermoelectric properties. The earth-abundant Mg2Si requires the method of cyclic hydrogen loading, which has two advantages: It suppresses the oxide formation, and promotes the driving force for formation of the intermetallic phase. While the clathrate BaCuSi and the Half-Heusler alloy (TiZr)NiSn, as most intermetallic alloys, can economically be produced by arc-melting, the Se-alloys CuTiSe and CuFeSe need to be processed by the powder-in-tube method and their Seebeck-voltage measurements up to +/- 0.04 mV/K and output power of 4 μW at ΔT= 400 K are reported here for the first time.
