Summary: The study confirms that mercury toxicity may be underestimated when the molar ratio of selenium to mercury is relatively high, as mercury binds extensively to selenoproteins, reducing the storage of bioavailable selenium for detoxifying MeHg. Additionally, the research shows that Hg(Sec)4 could severely deplete the bioavailable selenium in muscle tissue, potentially causing harm from mercury toxicity in terrestrial animals.

Summary: This study aimed to investigate the impact of different types of vegetable oils on the flavor profile of fried green onion oil. Using sensory analysis, gas chromatography-mass spectrometry (GC-MS), and electronic nose, the volatile flavor components of seven different kinds of fried green onion oils were identified and analyzed. The results showed that sensory analysis and electronic nose were effective in detecting the odor differences of the oils. A total of 103 volatile flavor components were identified, with key aromas including aldehydes and sulfur-containing compounds. Fatty acid compositions did not significantly change before and after frying, but the relative content differed. Unsaturated fatty acids had a significant influence on the flavor of frying oil.

Summary: In this study, the complete mitochondrial genome of Allium fistulosum was determined, which contained 44 genes including 26 protein-coding genes, 14 tRNA genes, and 4 rRNA genes. Phylogenetic analysis revealed a close relationship between A. fistulosum and Allium cepa. The high-quality mitochondrial genomic sequences of A. fistulosum presented in this study will serve as a valuable resource for various genetic, functional, evolutionary, and comparative genomic studies.

Summary: In this study, a genome-wide approach was used to identify 31 members of the KCS gene family in Allium fistulosum and classify them into 9 groups. These genes were unevenly distributed throughout the genome, and 7 of them had no introns. Analysis revealed that these genes were associated with hormone- or stress-responsive elements. Heatmap analysis showed that these genes were primarily expressed in the stems and leaf sheaths. Eight of them were significantly upregulated in response to salt, low temperature, and high temperature stress, while four were downregulated in response to drought stress.

Summary: This study investigated the changes in volatile compounds in Welsh onions subjected to heat and antioxidant treatments during storage. The majority of sulfur-containing compounds showed significant differences between untreated and heated Welsh onions. Partial least square discriminant analysis was used to differentiate the heated Welsh onion samples with different antioxidants.

Summary: This study evaluated the effects of main drying temperature (constant temperature, variable temperature (VT)) on the drying characteristics and product quality of scallion in vacuum freeze-drying (VFD) technology. The results showed that the drying time of VT group was 48.38% shorter than that of -20 degrees C group, with brighter scallion samples, lower volume shrinkage and tissue structure damage, and higher bioactives content. Additionally, the VT-VFD scallion better retained its flavor after rehydration compared to the constant temperature-VFD scallion. Thus, VT drying can significantly improve the drying characteristics and product quality of VFD scallion.

Summary: The use of BH intermediates as derivatization reagents significantly improves the tolerance to interference from transition metal ions in the generation of SbH3 and BiH3, and shows high tolerance in a wide range of acidity. The method has been successfully applied to the determination of Sb and Bi in complex samples, providing further understanding of the chemical behavior of borohydrides.

Summary: This paper presents the spatio-temporal dynamics of a Grimm-type microsecond pulsed glow discharge (mu PGD) in argon at 6 mbar. The occurrence of a high current peak during the discharge ignition is analyzed and the importance of displacement current is emphasized. The development of electron excitation temperature for argon atoms and ions at various distances from the cathode is measured. The spatio-temporal evolution of selected spectral lines of argon and copper atoms and ions is analyzed during different phases of the discharge. The results suggest that the behavior of spectral line emissions differs between the pre-peak and afterglow periods, with different lines reaching maximum intensity during these phases. The appearance time and decay time of the afterpeak are shorter for ions than for atoms. These findings are explained in terms of three-body recombination processes and ion mobilities.

Summary: In this paper, the combination of Tesla coil discharge (TCD) and laser-induced breakdown spectroscopy (LIBS) was used to enhance the emission of Al atomic lines and AlO molecular bands. The optimized distance between the TCD tip and the sample surface was found to be 5 mm, and the optimal laser energy was 25.1 mJ. Furthermore, TCD-SELIBS showed lower limits of detection (LoDs) for Cr and Pb elements compared to surface enhanced LIBS (SELIBS). The combination of TCD and LIBS is a promising technology for high-sensitivity analysis of heavy metals in water, with the advantages of simplicity, low cost, ease of operation, industrialization, and commercialization.

Summary: Titanium is an important metal widely used in various industries. Ilmenite minerals are the main source of titanium metal and can be found in igneous and metamorphic rocks as well as different types of deposits. To accurately determine U-Pb ages of ilmenite, a new calibration method and appropriate reference materials are urgently needed. Laser ablation sector field inductively coupled plasma mass spectrometry has been used to minimize matrix effects and zircon 91500 has been identified as a suitable reference material for measuring the Pb/U ratio in ilmenite. The direct calibration method using zircon 91500 as an external standard has been found to be effective for in situ U-Pb dating of ilmenite samples under different ablation settings.
