The primary goals included a background into the history of nuclear accident dosimetry, consolidating current dosimetry techniques within the NNSA/DOE complex, fostering collaboration among subject matter experts, and exploring novel technologies for potential implementation. The technical focus centered on investigating new and novel technologies, instrumentation methods, and analysis methods to develop recommendations for a potential nuclear accident dosimeter (NAD) to be universally deployed through the DOE complex. A multilaboratory and multinational Usergroup was established, conducting periodic meetings to facilitate knowledge exchange. The UNAD team has participated in two international nuclear accident dosimetry intercomparison exercises and one characterization exercise, where the existing LLNL NAD and a prototype alanine electron paramagnetic dosimeter NAD were deployed. Ongoing improvements are being made to the prototype NAD based on results from the exercises, laboratory studies, and collaboration with other laboratories. A machine learning algorithm to optimize the geometry and conversion factors of the current LLNL NAD is being implemented, and the resulting design will be tested in the next exercise.

It has several health benefits. However, its impacts may vary based on the concentration or dose. Hence, the purpose of the present study was to investigate the concentration-dependent impacts of naringenin on an <i>in vivo</i> model, <i>Drosophila melanogaster</i>. For this study, first-instar larvae were exposed to graded concentrations of naringenin until their third-instar or adult stage. Treated larvae were dissected to expose the visceral organs such as the brain, fat body, and gut to examine cytotoxicity. Moreover, ROS production and lipid droplet deposition were analyzed in the alimentary tract. The impact of graded concentrations of naringenin on life cycle parameters and longevity was further investigated. Results showed a biphasic impact of naringenin, where naringenin at lower concentrations (300–500 μM) exhibited its antioxidant effects by scavenging the ROS and improving the longevity of flies. Nonetheless, higher concentrations of naringenin caused excess ROS accumulation and lipid deposition in tissues of the digestive tract of treated individuals. Higher concentrations of naringenin (700 and 800 μM) were also responsible for the marked reduction in longevity and alteration in developmental duration of <i>D. melanogaster</i>. All of these results equivocally suggest that naringenin at low concentrations has health-promoting effects. However, the health benefits of this phenolic compound can be reversed at higher concentrations in <i>D. melanogaster</i>, triggering potential health concerns for humans. Therefore, it is recommended that the dose or concentration of naringenin should be standardized for its safe use.</p>","PeriodicalId":73648,"journal":{"name":"Journal of chemical health & safety","volume":"32 2","pages":"194–203 194–203"},"PeriodicalIF":0.0,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143675862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The four types discussed encompass 14500, 18650, 21700, and 26650 ones. Characteristic data from the calorimeter include onset temperature, critical temperature, maximum temperature, maximum self-heat rate, enthalpy change, and quantity of noncondensable gases. By integrating thermal hazard data, a box-plot was established and hazard ranking was clearly evaluated as 21700 &gt; 18650 non-LiFePO₄ (LFP) ≫ 26650 LFP &gt; 14500 non-LFP &gt; 18650 LFP &gt; 14500 LFP. Among all types of cylindrical lithium-ion batteries, the 21700 exhibits the worst consequence, which is attributed to the adoption of high energy density LiNi_0.8Co_0.15Al_0.05O₂ (NCA) and LiNi_<i>x</i>Mn_<i>y</i>Co_<i>z</i>O₂ (NMC) cathode materials. It was found that the critical temperature <i>T</i>_cr and maximum temperature broadly scattered; besides, most of the maximum self-heat rate (d<i>T</i>/d<i>t</i>) and pressure data were absent in literature. Definitions of onset temperature, critical temperature, trigger temperature, and possible heat sources to stimulate the severe thermal runaway were collected and found to be unimaginably divergent. A thermal analysis database was established to classify critical temperatures into high <i>T</i>_cr (above 180 °C), low <i>T</i>_cr (130–180 °C), and no <i>T</i>_cr. The low <i>T</i>_cr inducement is speculated to be caused by gas shock or electron breakdown after the separator melted, while the intrinsic characteristics of <i>T</i>_cr require further investigation. Thermal runaway features of cylindrical LIBs can be concisely classified as lowest <i>T</i>_onset of 88.0 °C (21700 NMC) vs highest <i>T</i>_onset of 220.0 °C (18650 LFP), highest (d<i>T</i>/d<i>t</i>)_max of 64536.0 °C min^–1 (21700 NCA) vs lowest (d<i>T</i>/d<i>t</i>)_max of 3.0 °C min^–1 (18650 LFP), highest <i>T</i>_max of 1257.9 °C (21700 NCA) vs lowest <i>T</i>_max of 243.2 °C (18650 LFP), highest Δ<i>n</i> of 314.0 mmol (18650 NCA) vs lowest Δ<i>n</i> of 23.3 mmol (14500 LFP), lowest <i>T</i>_cr of 145.5 °C (21700 NCA) vs (no <i>T</i>_cr) (14500 and 18650 LFP), and highest Δ<i>H</i> of 70.5 kJ (21700 NCA) vs lowest Δ<i>H</i> of 0.8 kJ (14500 LFP). In this work, the present research is reviewed in detail and future perspectives are proposed. This review on the critical characteristics of cylindrical batteries under thermal failure and thermal abuse provides a reference for solving intrinsic safety issues for lithium-ion batteries of the next generation.</p>","PeriodicalId":73648,"journal":{"name":"Journal of chemical health & safety","volume":"32 2","pages":"133–156 133–156"},"PeriodicalIF":0.0,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143675882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
