Res. Express 12 (2025) 116001Abstract:We report the optimization of the synthesis conditions for SmFeAsO0.80F0.20 (Sm1111) bulk superconductor using a cubic-anvil high-pressure (CA-HP) technique through both ex-situ and in-situ processes, under pressures up to 4 GPa and heating temperatures up to 1600 °C. A comprehensive characterization has been performed, including structural, microstructural, transport, and magnetic measurements. Our findings indicate that a modest growth pressure of approximately 0.5 GPa is sufficient for the formation of the Sm1111 phase via the ex-situ process. In contrast, the in situ process requires higher synthesis pressure (4 GPa) and temperature (1400 °C for 1 h) to achieve the Sm1111 phase with enhanced superconducting properties. Notably, the optimized in-situ process significantly reduces the reaction time needed for the formation of the Sm1111 phase compared to conventional synthesis process at ambient pressure (CSP), leading to an increase in the transition temperature by 3 K and improvements in the critical current density (Jc). Conversely, the optimized ex situ process maintains an onset transition temperature (Tc) of approximately 53 K, similar to that of CSP, while enhancing the Jc from ∼103 A-cm−2 to ∼104 A-cm−2 at 5 K. Despite these improvements, small amounts of impurity phases, as observed in CSP samples, persists in all Sm1111 samples prepared through either the in-situ or ex-situ CA-HP processes. These results suggest that the in-situ process under optimized conditions (1400 °C, 4 GPa for 1 h) can effectively improve the superconducting properties of Sm1111, resulting an increased Tc to 56 K. Furthermore, a comprehensive comparison with high gas pressure techniques, spark plasma sintering, and CSP methods suggests that the formation of small amounts of impurity phases in Sm1111 cannot be completely eliminated by various pressure techniques, even under the applied pressures up to 4 GPa. These results provide valuable insights for both fundamental studies and applied research, contributing to the further advancement of iron-based superconductors (FBS).Note: In the published article,Figure 1 is the block diagram.

Electrocatalytic properties and physicochemical identity of Cu-intercalated WO3 nanowires: application to electroreduction of nitrates in acid medium
No full textA hybrid catalytic system composed of copper(I)-oxide-derived copper-nanocenters immobilized within the network of tungsten oxide nanowires has exhibited electrocatalytic activity toward reduction of nitrates (NO3- and NO2-) in acid medium. The Cu-containing WO3 (Cu-WO3) catalytic system has been characterized using electrochemical, spectroscopic (Raman), microscopic (SEM), and X-ray (XPS) techniques. Evidence has been provided for insertion or intercalation of Cu active sites within the structure of hexagonal WO3 nanowires. In accordance with spectrophotometric measurements, it can be stated that the Cu-WO3 catalyst facilitates conversion of nitrates to ammonium ions, which have been identified as ammonia using indophenol method. Based on voltammetric diagnostic electroanalytical measurements with the additional Pt electrode and transfer to alkaline medium, formation of ammonia (but no hydrazine) has been confirmed. On the whole, the results are consistent with the view that the copper-intercalated catalytic centers, parallel to the reductive activity of the partially reduced non-stoichiometric tungsten oxides, induce conversion of nitrates and their reaction intermediates to ammonia type products. The Cu-WO3 have also been demonstrated to exhibit strong catalytic properties during reductions of other electrochemically inert reactants, such as oxygen and bromates.</p
