来源：ACS PublicationsDry reforming of methane (DRM) offers a promising strategy that concomitantly converts two greenhouse gases (CH4 and CO2) into valuable syngas (H2 and CO). Ni is a commonly used active metal component in DRM catalysts, while catalyst deactivation stemming from carbon accumulation and sintering remains a great challenge. Ensuring the availability of adequate active oxygen species to promote CHx (x = 0∼3) oxidation and inhibit particle aggregation is generally critical to prevent catalyst deactivation. Our study applied a simple coprecipitation method to synthesize Ni/CexMgO c...

来源：ACS PublicationsOptical quantum memories enable long-distance quantum information distribution, which is critical for establishing the global quantum Internet. Rare-earth qubits are promising candidates due to their spin-optical interfaces with excellent spin coherence and optical properties. When doped into inorganic solids, they display relatively long excited-state lifetimes and, in turn, low storage efficiencies, which are difficult to optimize via material design. Metal–organic frameworks (MOFs) allow fine-tuning of spin coherence and excited-state lifetimes through rational design of ...

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...
