Spin polarisation and non-isotropic effective mass in the conduction band of GdN.
J Phys Condens Matter
December 2024
GdN is a ferromagnetic semiconductor which has seen increasing interest in the preceding decades particularly in the areas of spin- and superconducting- based electronics. Here we report a detailed computational and optical spectroscopy study of the electronic structure of stoichiometric and nitrogen vacancy doped GdN. Based on our calculations we provide the effective mass tensor for undoped GdN, and some indicative values for electron doped GdN.

- This study reviewed opioid exposures in young children, specifically looking at data from America's Poison Centers® between 2016 and 2023, to assess the impact of fentanyl and medications for opioid use disorder.
- Out of 34,632 reports, most exposures (96.7%) were unintentional, with a median age of exposure being 2 years. While overall reported exposures decreased by 57.5%, there was a concerning 300% increase in deaths and major effects.
- The study emphasizes the importance of improving poisoning prevention strategies, as medications like buprenorphine and methadone showed a significant association with severe effects, alongside rising cases of fentanyl and heroin exposure.
Article Synopsis
- Thallium is a toxic metal, and this case details a young man who intentionally ingested elemental thallium purchased online, leading to dangerously high serum and urine thallium levels.
- The patient was treated with Prussian blue, a medication that binds to thallium, after having the ingested metal fragment removed via colonoscopy.
- Despite initial severe thallium levels that typically indicate fatal exposure, the patient showed no signs of toxicity after 23 days in the hospital, highlighting a need for more research on the effects of elemental thallium versus thallium salts.
This retrospective study analyzed 230 pediatric opioid exposures from a statewide poison control center over a 5-year period. Most exposures involved pharmaceutical opioids and children below 2-years-old. Narrative details were reviewed to identify uncommon sources of opioids involved in poisoning and highlight the need for tailored prevention strategies and guidance.
