AI Article Synopsis
- A new surface ionization ion-source has been developed for the JAEA-ISOL setup, designed to measure the first ionization potential of lawrencium (Lr, Z = 103).
- This updated ion-source improves upon the previous model, which effectively ionized lanthanides, by adding an additional filament for better operational control.
- The report highlights the successful ionization and mass separation of the isotope 27-s (256)Lr, produced through a specific nuclear reaction involving californium and boron.
Article Abstract
We have developed a surface ionization ion-source as part of the JAEA-ISOL (Isotope Separator On-Line) setup, which is coupled to a He/CdI2 gas-jet transport system to determine the first ionization potential of the heaviest actinide lawrencium (Lr, Z = 103). The new ion-source is an improved version of the previous source that provided good ionization efficiencies for lanthanides. An additional filament was newly installed to give better control over its operation. We report, here, on the development of the new gas-jet coupled surface ion-source and on the first successful ionization and mass separation of 27-s (256)Lr produced in the (249)Cf + (11)B reaction.

Introduction: Successful retrieval of from porcine clinical specimens has been rarely described, and data has only been obtained from a few swine-producing countries. Therefore, the aim of this study was the isolation of recovered from a specimen originating from a commercial pig farm located in Poland.
Material And Methods: Seven dead 12-week-old pigs weighing 24-26 kg with joint swelling of the hind legs were selected on a modern farrow-to-nursery farm in Poland in October 2023.

Tea is one of the most consumed beverages in the world and presents a great aromatic diversity depending on the origin of the production and the transformation process. Volatile organic compounds (VOCs) greatly contribute to the sensory perception of tea and are excellent markers for traceability and quality. In this work, we analyzed the volatile organic compounds (VOCs) emitted by twenty-six perfectly traced samples of tea with two analytical techniques and two data treatment strategies.

This review follows the PRISMA guidelines to provide a systematic review of 115 peer reviewed articles that used non-targeted analysis (NTA) methods to detect per- and polyfluoroalkylated substances (PFAS). This literature highlights the significant positive impact of NTA in understanding PFAS in the environment. Within the literature a geographical bias exists, with most NTA studies (∼60 %) conducted in the United States and China.

Despite the success in COVID-19 mRNA vaccines, direct local delivery of mRNA into the lung by inhalation would greatly reinforce the treatment of pulmonary pathogens and diseases. Herein, we developed lipid nanoparticles (LNPs) from degradable ionizable glycerolipids for potent pulmonary mRNA delivery via nebulization.

Article Synopsis
- Bloodstream infections need quick bacterial identification for effective treatment, with traditional methods being slow.
- The study compared direct identification using MALDI-TOF MS with the post-culture method, finding that while direct identification had a lower success rate (64.8%), it provided results in under an hour.
- Despite its limitations, the direct method could significantly enhance diagnosis speed, making it a potentially valuable tool in conjunction with established methods.
