U-Pb zircon in situ dating with LA-MC-ICP-MS using a mixed detector configuration

Anais da Academia Brasileira de Ciências, 2012
The LA-MC-ICP-MS method applied to U-Pb in situ dating is still rapidly evolving due to improvements in both lasers and ICP-MS. To test the validity and reproducibility of the method, 5 different zircon samples, including the standard Temora-2, ranging ...

Precise Analysis of Gallium Isotopic Composition by MC-ICP-MS

, 2016
Though an isotope approach could be beneficial for better understanding the biogeochemical cycle of gallium (Ga), an analogue of the monoisotopic element aluminum (Al), the geochemistry of Ga isotopes has not been widely elaborated.

Single-Stage Extraction Technique for Ce Stable Isotopes and Measurement by MC-ICP-MS

, 2021
The separation of Ce from other rare earth elements has not been well established because of their similar geochemical properties. In this study, we report a single-stage extraction technique to purify Ce from natural samples with Eichrom DGA resin. This

Biofilm‐Binding Phages Enhance Biofilm Eradication by Synergistic Photothermal and Photodynamic Therapy

Advanced Science, EarlyView.
Engineered phage‐based trifunctional nanofibers are developed for synergistic biofilm eradication. Biofilm‐binding phages, armed with AuNPs and TCPP, serve as both warheads and scaffolds, endowing the phototherapy agents with biofilm‐anchoring ability. Upon light irradiation, AuNPs induce photothermal therapy, while TCPP generates 1O2 for photodynamic ...

Provenance of Zhou Dynasty bronze vessels unearthed from Zongyang County, Anhui Province, China: determined by lead isotopes and trace elements

Heritage Science, 2021
Thirteen Zhou Dynasty bronze vessels and two slags from Zongyang County along the north bank of the Yangtze River in Anhui were analyzed by LA-MC-ICP-MS and EDXRF. The results of lead isotope analysis showed that there were two kinds of lead materials in

Harmonizing Rigidity and Flexibility: Embedding COF Quantum Dots Into Extracellular Matrix Gel as Carbon Monoxide Depot for Acoustically Triggered Time‐Programmable Anti‐Infective Therapy

Advanced Science, EarlyView.
A rigid‑flexible integrated CO depot is engineered by embedding rigid COFQDs into a flexible ECM gel network. The rigid framework enables high‑capacity CO storage and sonodynamic bacterial killing, while the flexible ECM gel controls sustained CO release, collectively eradicating multidrug‑resistant infection and promoting scarless healing.
