来源：ACS PublicationsCe-based polar materials are promising NLO candidates due to their unique electronic configuration of [Xe] 4f15d16s2 and diverse coordination modes. Ce4+ compounds are highly desired candidates for advanced nonlinear optical materials, yet the development of trivalent cerium-based NLO materials exhibiting a high second-harmonic-generation (SHG) response (above 3.0 × KDP) remains a great challenge. Herein, a new cerium iodate, Ce2(IO3)6(H2O), crystallized in the polar space group Pn (No. 7), was discovered by introducing rare-earth cations into iodates with a hydrotherma...

来源：ACS PublicationsPerovskite oxides display correlated electrical, magnetic, and thermal properties that can be further tuned in the thin-film limit, making them contenders for next-generation electronics. Measuring thermal transport in thin films is challenging, because traditional techniques are dominated by the substrate. Here, frequency-domain thermoreflectance (FDTR) of an epitaxial NdNiO3 thin film reveals a sharp change in out-of-plane thermal conductivity across the metal–insulator transition. Complementary frequency-domain photoreflectance (FDPR) reveals a large change in ambipolar d...

来源：ACS PublicationsDiatomic catalysts (DACs) hold inherent superiority in atomic economy and synergistic catalysis for complex multi-intermediate reactions. However, several fundamental challenges persist, including typically low diatomic loading (2 wt %), ambiguous diatomic site identification, and most critically, the lack of universal design principles for rational synthesis. Herein, we present a general synthetic strategy guided by the hard–soft acid–base (HSAB) principle, successfully yielding 14 rare-earth (RE)-based DACs with record-high metal loadings (12.8–30.7 wt %, 3.2–5.4 at. %) an...
