来源：ACS PublicationsHybrid organic–inorganic heterostructures offer a promising design toward low-cost light-emitting devices by combining the high luminescence efficiency of organic semiconductors with the stability and charge transport capability of metal oxides. In this work, TiO2 thin films doped with trivalent lanthanide ions (Er3+ and Yb3+, 2 and 4 at % concentrated) were prepared by the sol–gel dip-coating method and coupled to a quinoline-based donor–π–acceptor small molecule, 4-(6-(diethylamino)-4-phenylquinolin-2-yl) benzoic acid. X-ray diffraction confirmed preservation of the anatas...

来源：ACS PublicationsComplex, multicomponent liquids with hierarchical structure and phase transitions are encountered in many natural and industrial processes, including in chemical separations. One notable example is aggregation and organic phase splitting in liquid–liquid extraction (LLE) of metal ions. While these two phenomena that have long been closely associated, a mechanistic link between mesoscale structure and the capacity-limiting organic phase splitting remains elusive due to complexity of these systems. Here, we combine small-angle X-ray scattering (SAXS), X-ray photon correlation ...

来源：ACS PublicationsDeveloping high-performance mid-infrared nonlinear optical (NLO) crystals is crucial for modern laser technology. Here, three novel salt-inclusion Eu-based chalcogenides (SICs) were successfully synthesized via a guest-framework modulation strategy: [KEu4Cl][Ge3S10] (1), [Eu4Cl2][Ge3S9] (2), and [Eu7Cl2][Ge6Se18] (3). They exhibit diverse structures, where the [Ge2Se6]4– dimer violates Pauling’s third rule. 1–3 exhibit SHG responses of 0.3–0.9 × AGS and suitable bandgaps of 1.88–2.15 eV. Notably, 3 is the first Ge-containing SIC to demonstrate phase-matching behavior. T...

来源：ACS PublicationsRare-earth elements are strategic materials essential for renewable energy, electronics, and electric mobility. The growing demand emphasizes the need for a sustainable and efficient supply, considering environmental and economic aspects. Among their main applications are neodymium–iron–boron (Nd–Fe–B) permanent magnets, whose production chain presents significant environmental impacts─from mining to final manufacturing. This study assesses the life cycle of Nd–Fe–B magnets in the Brazilian context, following ISO 14040 and ISO 14044 standards. System modeling was performed i...
