来源：ACS PublicationsRare-earth-doped glasses have great potential in magneto-optical applications due to their high transparency and Verdet constant. However, their synthesis not only requires a high-temperature treatment over 1000 °C, but also involves the use of many expensive heavy rare-earth elements, which significantly increases the manufacturing cost. In this work, a desolvation method is used to synthesize a hybrid glass using a cost-effective Ce element. The use of ethanol as a solvent not only lowers the synthesis temperature down to 90 °C, but also avoids the hydrolysis of ...

来源：ACS PublicationsStrong demand for rubber, coupled with limited natural rubber supply, has accelerated the development of synthetic alternatives. Metal-catalyzed polymerization is a key route to highly stereoregular rubber materials. Among the developed catalysts, rare-earth metal catalytic systems have attracted attention because of their relatively low toxicity, high catalytic activity, and pronounced stereoselectivity. A series of quinolyl-based pincer rare-earth chlorides was synthesized through the reactions of quinolyl-based lithium of the ligands with RECl3. The products obtained from...

来源：ACS PublicationsIn this study, ZIF-8/HKUST-1 and ZIF-67/HKUST-1 composite materials were fabricated via a stepwise solvent-assisted synthesis route. The materials were characterized by Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and N2 physisorption (BET). The La3+ adsorption performance was systematically evaluated through batch experiments under varying pH, contact time, initial concentration, and temperature. The experimental data were fitted to kinetic, isotherm, and thermodynamic models to elucidate the underlying adsorp...

来源：ACS PublicationsBismuth-doped rare earth iron garnet (Bi:RIG) is a promising magneto-optical material for use in 1310 nm optical isolators. The top-seeded solution growth (TSSG) method has advantages for growing high-quality crystals. However, the Bi concentration in the bulk iron garnet crystal grown by this method is low, leading to a small specific Faraday rotation angle (θF). To increase θF in the Bi:RIG crystal in this paper, a large ion radius of Nd3+ would be introduced into the RIG garnet crystal to expand the unit cell and enhance the Bi3+ concentration. Thus, high-quality and heav...
