The physico-chemical characterization of thermal and mineral waters is a comprehensive process that integrates knowledge and practice from different scientific fields. When used in direct contact with human skin, whether for bathing or for use in topical products, a toxicological analysis of thermal and mineral waters must also be performed. This work is an example of a multidisciplinary approach to investigate the safety of concrete thermal and mineral water from the Pannonian Basin for use in cosmetics. A detailed physicochemical characterization was performed together with the subsequent safety assessment of the final cosmetic product, coupled with cheminformatics and bioinformatics tools used to predict physicochemical properties, pharmacokinetics, determination of descriptors to assess bioactive potential and evaluation of possible biological pathways and interactions. The results show that the tested thermal and mineral water is a promising resource for use in cosmetic products that can help maintain skin integrity and improve its condition. The toxicological evaluation showed that the tested water is acceptable as an ingredient in a face cream for adults, excluding pregnant and breastfeeding women.

In particular, a flexible three-dimensional (3D) porous electrode capable of resisting high humidity environments (fog) is expected to have a broader range of applications in smart wearable devices. Hence, a superhydrophobic and porous ODT/MWCNTs/MeS electrode has been proposed and investigated for its ability to respond stably under a specific applied voltage. The long alkyl chains of 1-octadecanethiol (ODT) are triggered by the applied voltage to induce chain stretching. The static contact angle of water on the 3D porous electrode is 158.7° at a supply voltage of 0 V, increasing to 162.1° when the voltage is 10 V. The numerous long alkyl chains on the MWCNT coating have been shown to be effective in trapping fog, which can accumulate on the superhydrophobic electrodes to form a liquid film. The <em>C</em>–<em>V</em> curve of the superhydrophobic electrodes remains almost unaffected at a supply voltage of 10 V, even under continuous fog spray. Moreover, the <em>i</em>–<em>t</em> curve demonstrates that the continuous fog has minimal impact on the sensitivity and stability of ODT/MWCNTs/MeS electrodes at 10 V. In conclusion, this superhydrophobic and porous electrode, as a smart wearable sensor, can be activated by a supply voltage to achieve a stable response in a humid environment.</p>","PeriodicalId":102,"journal":{"name":"RSC Advances","volume":" 22","pages":" 17435-17441"},"PeriodicalIF":3.9,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ra/d5ra03009a?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144140072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Steroids are widely abused due to their ability to promote protein synthesis, enhance muscle growth, and improve athletic performance, leading to significant unfair competition. Carbon isotope ratios (CIRs) are effective in distinguishing between endogenous and exogenous steroid sources, making steroids an ideal target for isotope ratio analysis in anti-doping analysis. High-precision isotope ratio measurements using Gas Chromatography-Isotope Ratio Mass Spectrometry (GC-IRMS) require high separation between the target steroid and adjacent compounds to avoid interference. However, steroid concentrations in biological matrices like urine and blood are often trace and accompanied by a large number of coexisting interferents, making purification challenging. These limitations have partially restricted the use of compound-specific isotope analysis in doping detection. This review highlights the latest advancements over the past decade in sample preparation, liquid-phase purification, and both gas-phase and liquid-phase isotope ratio mass spectrometry (IRMS) techniques.
