Summary: Epoxy molding compounds, consisting of a polymer-based matrix, inorganic filler particles, and various additives, are widely used in the semiconductor industry for encapsulation. This study explores the use of a Tandem LA-ICP-MS/LIBS approach to comprehensively characterize epoxy molding compounds and construct a classification model capable of distinguishing different types. The analysis of 29 samples from 4 suppliers using exploratory data analysis and a Random Decision Forest-based classifier demonstrates the potential of this method.

Summary: A total of 170 whisky samples from 11 countries were analyzed for their elemental profiles. Copper was found to be an element that distinguished single malt and blended types of whisky, with higher concentrations in single malt Scotch whisky. Samples from the same brands but different bottles showed common elemental profiles. Additionally, the content of copper and manganese increased with longer aging time of Scotch whisky.

Summary: In this study, we analyzed the elemental profile of 46 edible seaweed samples purchased in the United States. The results showed that the distribution of elements was closely related to the taxonomy of the seaweed species. The levels of certain elements varied significantly within the same species, possibly due to geographic origin or food processing conditions. Higher accumulation of toxic elements Cd and Pb was observed in wakame, hijiki, and nori. Additionally, there were multiple pairs of highly correlated elements in seaweed, as well as triple and quintuple correlations of certain elements.

Summary: This study investigated the chemical and cytotoxic properties of a commercial coffee made from less used date palm fruits. The roasted seeds were found to be a source of potassium and calcium, and the methanol extract showed the highest antioxidant activity and total polyphenol content. The coffee was decaffeinated and contained phenolic compounds and vitamins. The organic extracts showed lower cytotoxicity against cell lines.

Summary: The study found that red wines contain higher levels of certain elements compared to other wine types (white and rose), while white wines have higher levels of other elements and rose wines have higher concentrations of iron and uranium. The study also revealed that in some samples, the maximum levels of certain metals slightly exceeded OIV standards, but overall the wines contained lower levels of heavy metals, suggesting they are safe for consumption. Additionally, wines from Poland, USA, and Australia showed distinctive elemental fingerprints, with different characteristic metals for identification of country of origin.

Summary: The carbonatites in the southern margin of the North China Craton are characterized by abundant quartz and are closely associated with Mo-(REE) deposits. The fluid inclusions in the quartz of the carbonatites show high homogenization temperatures and low salinities, containing concentrations of La, Ce, Pr, Nd, Sr, and Ba. These findings suggest a genetic relationship between the Mo-(REE) deposits and the quartz-rich carbonatites.

Summary: The current study assessed the effects of a natural plant-based dietary supplement containing lemon verbena extract on stress management and sleep quality. The results showed that participants taking the supplement experienced a significant reduction in perceived stress and cortisol levels after 8 weeks. Furthermore, the supplement users reported lower stress levels even during the washout period, indicating a lasting effect. Their sleep quality also improved, with a stronger effect observed in women, as evidenced by sleep tracking data. Therefore, lemon verbena extract purified in phenylpropanoids appears to be a natural solution for improving stress and sleep quality.

Summary: Single particle inductively coupled plasma mass spectrometry (spICP-MS) has been used to determine metallic nanoparticles (NPs) in air. Different extraction strategies and extracting solvents were investigated, and a method for extracting metallic NPs from filters in 4 minutes was developed. The study also found that microquartz fiber filters had better NPs capturing performance. This method has been successfully applied to detect NPs in environmental monitoring stations.

Summary: The number of studies on nanomaterial characterization in organic matrices using spICP-MS is increasing, but limited knowledge exists about the non-spectral interferences caused by this matrix. This study aims to investigate non-spectral interferences on nanoparticle characterization (number concentration and size distribution) by organic materials with spICP-MS. The results show that 10% w/w ethanol causes positive matrix effects on the number concentration, while the size distribution can be affected positively or negatively depending on the plasma conditions, instrument characteristics, and nanoparticle composition. Internal standardization can help mitigate these organic non-spectral interferences.

Summary: This study aimed to assess the Cd(II) bioremediation potential of Hfx. mediterranei R4. It was found that the cell doubling time of Hfx. mediterranei increased three times in the presence of Cd(II) in the culture medium. Moreover, the microorganism was able to accumulate Cd, with the highest accumulation observed at a concentration of 0.4 mM. Additionally, the presence of Cd(II) affected the levels of other elements in the biomass, increasing the levels of K and Mn while reducing the levels of Mg and Zn.

Summary: The objective of this study is to evaluate different competitive aptamer assays for the detection of beta-conglutin in flour samples using inductively coupled plasma mass spectrometry (ICP-MS). Two competitive aptamer assay schemes were developed, one using thiolated aptamers on gold nanoparticles and the other using biotinylated aptamers linked to streptavidin-AuNPs. The influence of ICP-MS detection mode on assay performance was explored. The optimized condition achieved a LOD of 2 pM, significantly improving the LOD compared to previous studies.

Summary: This study explores the chelating capabilities of 1-butyl-2-diphenylphosphino-3-methylimidazolium hexa-fluorophosphate (BDPPIMPF6) as a task-specific ionic liquid (TSIL) for metal extraction/preconcentration procedures. BDPPIMPF6 specifically forms chelating complexes with several elements of Group 10 (Pd and Pt) and Group 11 (Ag and Cu) of the Periodic Table. It has been exploited for developing a novel methodology for the simultaneous determination of Ag, Cu, Pd, and Pt with high enrichment factors and low limits of detection.

Summary: According to reports, volcanoes release several tonnes of mercury and other heavy metals every year through eruptions, fumaroles, or diffuse soil degassing. This study aims to evaluate the accumulation of these metals in the central nervous system and the presence of heavy metal detoxification mechanisms in wild mice chronically exposed to an active volcanic environment. The results show a higher load of metals and increased immunoreactivity for metallothionein 2A in the exposed mice, indicating a possible neuroprotection process.

Summary: Characterization of nanomaterials (NMs) using single particle inductively coupled plasma mass spectrometry (spICP-MS) relies on assessing transport efficiency. This study evaluated the role of aerosol transport on NMs characterization and found that transport efficiencies of the solvent, ionic Pt, and PtNPs differed significantly. These findings are important for spICP-MS metrology as some strategies assume similar transport of different species into the plasma, leading to inaccurate NMs characterization depending on operating conditions.
