In the current study, a novel electrochemical sensor has been constructed using Co-doped MgNi2O3 nanoparticles as electrode material for the simultaneous detection of riboflavin (RF), serotonin (SE), and pyridoxine (PY). At optimal conditions, the Co-MgNi2O3 nanoparticles–modified glassy carbon electrode exhibited three well-defined anodic peaks corresponding to the oxidation of RF, SE, and PY in phosphate buffer saline (pH 7.0). The fabricated electrode Co-MgNi2O3/GCE yielded enhanced peak currents over wide linear ranges of 1–900 μM, 0.1–70 μM, and 1–120 μM for RF, SE, and PY with the corresponding limits of detection (S/N = 3) for the analytes as 1.92, 0.70, and 1.04 μΜ, respectively. Real sample analysis of constructed sensors has been carried out successfully in human blood serum, urine, and pharmaceutical samples. The recoveries varied from 93.33 to 112% in spiked real samples, with relative standard deviations less than 8%. In the case of real samples, the recovery values vary from 95.0 to 103.33% with relative standard deviations less than 3.63%. The proposed relatively new electrode material Co-MgNi2O3 has been synthesized by chemical method which offers the potential for fabricating low-cost electrochemical sensors for biomedical applications.<h3>Graphical Abstract</h3>\u0000 <div><figure><div><div><picture><source><img></source></picture></div></div></figure></div>\u0000 </div>","PeriodicalId":599,"journal":{"name":"Ionics","volume":"29 11","pages":"4851 - 4862"},"PeriodicalIF":2.8,"publicationDate":"2023-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71909907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this regard, we carried out a theoretical study to investigate the 2D multiphase molybdenum disulphide (1T/2H MoS2) anode material using density functional theory (DFT) and ab initio molecular dynamics (AIMD) simulations. Our observations confirmed the efficacy of this material as an anode.

Notably, the anode material exhibits an ultralow energy barrier of 0.04 eV, surpassing that of extensively studied 2D materials. By employing a wide range of Mg2+ concentration during the charging process, we achieved a high specific capacity of 4496.77 mAh g−1 ions, coupled with an average operating voltage of 0.04 V.

Firstly, different ratios of xNa2MnPO4F-(1-x)Na3V2(PO4)2F3 materials were synthesized and discussed to obtain 0.6Na2MnPO4F-0.4Na3V2(PO4)2F3 material as optimal ratio.
