New lanthanide coordination polymers (Ln-CPs) from 2-hydroxyterephthalate: Excited-state intramolecular proton transfer (ESIPT) and sensing capabilities来源：X-MOLEleven new coordination polymers (Ln-CPs), Ln2(htp)3(DMF)4∙x(DMF), where Ln = La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er and htp = 2-hydroxyterephthalate were synthesized, structurally characterized and their photoluminescence properties studied. Time-dependent density-functional theory (TD-DFT) calculations were used to explain key differences and similarities in excitation and emission spectra of Ln2(htp)3(DMF)4∙x(DMF) (Ln = La (x = 2...

来源：ACS PublicationsUnderstanding the influence of processing routes on grain boundary structure and crystallographic texture is essential for optimizing the magnetic performance of nanocrystalline Nd–Fe–B magnets. In this study, a five-parameter crystallographic analysis was employed to systematically investigate the influence of spark plasma sintering and hot deformation sintering on the grain boundary plane distribution and crystallographic texture of nanocrystalline Nd–Fe–B magnets. Its reveals that the hot deformation process confers marked advantages in promoting strong c-axis texture and...

来源：ACS PublicationsThe rare-earth intermetallic compound NdCuSb2 possesses an antiferromagnetic (AFM) order below TN = 3.78 K, with magnetic moments aligned along the b axis. Here, we systematically investigate the pressure evolution of the structural and electronic properties of a NdCuSb2 single crystal up to 53.4 GPa. With initial increasing pressure, TN decreases rapidly and eventually vanishes above PC = 3.5 GPa, indicating the complete suppression of the pristine AFM state. Upon further compression to 6.0 GPa, a new anomaly, T*, around 4 K is observed and shows a monotonous increment with...

来源：ACS PublicationsThe healing of infected wounds is often hampered by a dynamically evolving pathological microenvironment. Conventional static therapeutic approaches lack the adaptability to address these changes. Herein, a pH/reactive oxygen species (ROS) dual-responsive cerium single-atom nanozyme spray was developed, intelligently adapting to the dynamic microenvironment of infected wounds. In the initial infection, it responds to an acidic microenvironment and exerts potent antibacterial activity by exhibiting cascade glucose oxidase (GOD)- and peroxidase (POD)-like activities to generat...
