Polymer-guided grafting of single W atoms onto titanate nanotubes increases SERS activity in semiconductors.

Metal single atoms have been demonstrated to induce surface-enhanced Raman scattering (SERS) due to their effectiveness in the modification of electronic structure. However, precisely modulating the relative positions of metal single atoms on sub-nanolattices remains a formidable challenge, which makes SERS studies of metal single atoms dependent on localized environments still lacking. Herein, we rely on polyethylene glycol (PEG) as a soft template to achieve the modulation of the relative positions of W atoms on titanate nanotubes (W-TNTs) and probe the local-environment-dependent SERS induced by metal single atoms based on this technique.

Promoting Mn Spin-State Transitions from t to e through Ni Doping in Antiperovskite CuNMn for Highly Efficient Ammonia Synthesis.

The electrochemical nitrogen reduction reaction (e-NRR) offers a sustainable approach to ammonia synthesis under ambient conditions, with the potential to replace the energy-intensive Haber-Bosch process. Despite significant progress in this promising field, the low NH yield rate and limited Faradaic efficiency (FE) remain formidable challenges. Here, we introduce antiperovskite CuNiNMn, where partial substitution of Cu by Ni in CuNMn is developed as an effective and robust e-NRR electrocatalyst.

Dynamic behavior of resistivity irreversibility induced by thermal cycling in perovskite charge ordering manganites.

The mechanism behind resistivity irreversibility triggered by thermal cycling in perovskite charge-ordering manganites has yet to be unraveled, largely due to the absence of a coherent explanation. The application of a low-temperature electron-paramagnetic-resonance (EPR) spectroscopy technique is essential to distinguish between ferromagnetic and antiferromagnetic distributions. Here, we experimentally show that the fraction of the ferromagnetic phase in NdCaMnO induced by slight Cr-substitution diminishes with the increase of thermal cycling frequency, as observed EPR.
