来源：ACS PublicationsGermanate-based compounds are emerging as highly appealing candidates for nonlinear optical (NLO) applications due to their favorable electronic configurations, robust structural frameworks, and wide optical transparency. However, germanate NLO crystals with a short ultraviolet (UV) cutoff edge and high second-harmonic generation (SHG) response are urgently demanded. Here, a new noncentrosymmetric rare-earth germanate, K3YGe3O9 (KYGO), was successfully prepared via the spontaneous crystallization technique. KYGO crystallizes in the triclinic P1 space group and features a thr...

来源：ACS PublicationsRare-earth iron garnet (RE3Fe5O12) films are promising insulating ferrimagnets. They can show low magnetic damping, perpendicular magnetic anisotropy, and ultrafast spin dynamics, which makes them ideal for spin transport applications. In this work, we investigate the interaction between the magnetic sublattices in Er3Fe5O12 thin films grown by pulsed laser deposition on a Gd3Ga5O12 substrate. Structural and magnetic characterization reveals high-quality single-crystal growth, with a compensation temperature close to the reported bulk value (∼80 K). Magnetic phase diagrams b...

来源：ACS PublicationsPure cobalt ferrite (CoFe2O4) and yttrium-doped cobalt ferrite (CoY0.2Fe1.8O4) nanofilms were fabricated using nanoparticles synthesized via a self-combustion route and assembled through the Langmuir–Blodgett (LB) technique. These nanostructured films were employed as anodes to investigate the effects of Y3+ incorporation in the structure and the application of an external magnetic field on the oxygen evolution reaction (OER). Transmission electron microscopy and X-ray diffraction confirmed a reduction in particle and crystallite size upon Y doping, while X-ray photoelectron...

来源：ACS PublicationsThe development of 3D hydrophobic porous adsorbents for oil/water separation that are inexpensive, easy to fabricate, highly efficient, and physically and chemically durable continues to be a major research focus and a critical issue to be addressed. In this study, a facile and universal wettability transition strategy of amphiphilic melamine sponge (MS) was developed via simple dip-coating MS in rare earth ion solutions, taking Ce ion as a representative example. The formation of abundant coordination bonds between Ce ions and nitrogen atoms on a MS skeleton effectively dec...
