Curcuma longa debranched starch assisted synthesis of cerium oxide nanoparticles and its antioxidant, anticancer, antimicrobial, and anti-biofilm activities 来源:X-MOLNowadays, there is a growing emphasis on eco-friendly methods for synthesizing metal nanoparticles (NPs), that avoid chemical processes and the production of harmful substances. In this study, we present a novel green approach for preparing cerium oxide nanodots (CeO2NPs) using Curcuma longa debranched starch as a reducing and capping agent via the sol-gel method. The prepared CeO2NPs were characterized using various techniques, in...

Trivalent rare-earth ions (RE3+) exhibit sharp 4f–4f transitions that are highly sensitive to dipole–dipole interactions (DDIs), yet the intrinsic short-range of DDIs restricts their application in long-distance quantum coupling. Here, we demonstrate a plasmonic nanocavity pair that simultaneously couples to upconversion nanoparticles (UCNPs) and quantum dots (QDs), enabling enhanced emission and inter-emitter interaction. The combined effects of Purcell enhancement and surface plasmon polariton (SPP) propagation extend the DDI-mediated energy transfer over a record distance exceeding 7.5 μm, ...

来源:ACS PublicationsTo better understand the interactions of rare earth elements (REE) with anaerobic microorganisms, we explored the proteome response of a Clostridium strain to europium (Eu) and its adjacent lanthanide, samarium (Sm), comparing them with the well-studied metals iron, calcium, and zinc. Our findings showed that Eu and Sm induced a number of proteomic changes consistent with Fe, Ca, and Zn, but Eu enhanced expression for ATP synthase and electron transfer flavoproteins, while Sm increased expression of proteins associated with butyric acid metabolism. In contrast, Fe reduced AT...

来源:ACS PublicationsThe development of high-performance deep-ultraviolet (deep-UV) second-order nonlinear optical (NLO) crystals that simultaneously combine noncentrosymmetric crystal structure, broad transparency, strong second-harmonic generation (SHG) activity, and high thermal and chemical stability remains a formidable challenge due to intrinsic trade-offs among these properties. Herein, we present a multicomponent structural design strategy that enables the rational synthesis of a new KBe2BO3F2 (KBBF)-like rubidium lanthanum sulfate, RbLa(SO4)2. In this crystal, the highly polarizable [La...
