This process is based on anodic dissolution of the workpiece through an oxidation reaction. For many years, cyanide-based electrolytes were used to electropolish precious metals like gold and its alloys. The need for safer working conditions encouraged the replacement of cyanide by other complexing agents, mainly thiourea. However, the latter is also harmful. Therefore, the aim of this work is to electropolish pure gold and 18k jewelry gold alloys (yellow, rose, red and gray) in a cyanide-free electrolyte, to evaluate the electrochemical behavior and the influence of different parameters. For this purpose, a previously reported solution based on hydrochloric acid and glycerol was used. In the first part of the study, the influence of chloride concentration on pure gold EP was determined by electrochemical techniques and surface properties analysis. The effects of adding ethanol to electrolyte composition and of variating rotation speed were also evaluated. The best results were obtained for a HCl 50% vol. - Glycerol 25 % vol. - Ethanol 25 % vol. electrolyte at a rotation speed of 1000 rpm. In the second part of the study, this solution was used to electropolish 18 K gold alloys. Silver-containing alloys were not uniformly polished due to the formation of an AgCl film on the surface that partially masks the substrates.</p></div>","PeriodicalId":34303,"journal":{"name":"Applied Surface Science Advances","volume":null,"pages":null},"PeriodicalIF":6.2,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666523924000321/pdfft?md5=3507812dce2beae275c063fdb135d02f&pid=1-s2.0-S2666523924000321-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140619903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, prompt action is needed to develop innovative therapeutic interventions, as conventional treatments exhibit severe adverse effects and have limited efficacy. This study aims to develop an innovative therapeutic intervention for breast cancer using biosynthesized nanoceria. Nanoceria has gained significant importance in the medicinal field due to its biocompatibility, dual capabilities as both antioxidant and prooxidant, and specific cytotoxicity towards cancer cells. Herein, nanoceria was biosynthesized using <em>Echinochloa frumentaceae</em> grain extract (EFNC) due to its eco-friendly and cost-efficient nature, and it was systematically investigated using standard characterization techniques. Furthermore, their anticancer efficacy against MCF-7 breast cancer cell lines was studied using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) cell viability assay, and the occurrence of apoptosis was determined using acridine orange/ethidium bromide (AO/EtBr) staining. Significantly, EFNC exhibited superior anticancer efficacy even at lower concentrations (10 µg/mL), and the IC₅₀ value was found at 47.32 µg/mL. In addition, the observed bright green and orange-red fluorescence, along with fragmented/condensed chromatin features in AO/EtBr staining clearly indicated that the EFNC caused cell death through the apoptotic route. One potential factor contributing to the observed anticancer effectiveness of EFNC could be its prooxidant properties within cancer cells. These properties ultimately enhanced oxidative stress, induced the accumulation of reactive oxygen species (ROS), and led to apoptosis. Hence, the <em>in vitro</em> analysis substantiated the significant anticancer efficacy of EFNC, suggesting its potential utility as a promising therapeutic agent in anticancer treatment. These findings pave the way for further exploration and development of EFNC as a valuable candidate for addressing cancer-related challenges.</p></div>","PeriodicalId":34303,"journal":{"name":"Applied Surface Science Advances","volume":null,"pages":null},"PeriodicalIF":6.2,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S266652392400031X/pdfft?md5=52b50156ecad198618a075425d6cec4e&pid=1-s2.0-S266652392400031X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140558455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An optimum pH value of 7 was determined for both individual and multi-component adsorption. The optimal dosage of granulated Fe-PC was determined to be 1.5 g/L for Tz and 3 g/L for Tc, resulting in constant removal rates of 80 % for Tc and 90 % for Tz. Tizanidine showed a higher affinity for powdered or granulated Fe-PC compared to tetracycline, due to its smaller molecular size and increased amine functional groups. Consequently, Tz showed improved kinetic rates (initial pseudo-second order sorption rates of 170.79 and 25.62 mg/g.h for Tz and Tc, respectively) and equilibrium capacities (maximum monolayer adsorption capacity of granulated Fe-PC at room temperature over Tc and Tz, 54.89 mg/g and 66.40 mg/g). Granulation affected the kinetic rate for both adsorbates, albeit with a more pronounced effect for Tc. The adsorption of Tz was less sensitive to temperature changes, indicating a lower enthalpy change of adsorption (14.24 and 77.91 kJ/mol for Tz and Tc, respectively). HCl for Tc and NaCl for Tz were identified as optimal desorption eluents, confirming the involvement of cation exchange in Tz adsorption. Surface functional group analysis confirmed the proposed complexation mechanisms. Tz consistently showed a higher affinity for granular Fe-PC than Tc, especially at lower adsorbent dosages.
