The effects of electrolyte composition and current density on electrochemical dissolution behavior were experimentally investigated. ECP parameters were optimized through a comprehensive evaluation of surface roughness, material removal rate (MRR), and thickness reduction. The results indicate that the formation of a supersaturated salt film in the NaCl-EG electrolyte can suppress the uneven dissolution of carbides and matrix, but its improvement on roughness is limited. Compared with the NaCl-EG electrolyte, the NaCl-aqueous electrolyte achieves comparable surface roughness while increasing the MRR by at least 336.21 %. Furthermore, to address the challenge of polishing internal cavity surfaces of LPBF parts, a conformal tool electrode design strategy is proposed. Through this approach, partially melted particles on the inner surface of curved channels were successfully removed, reducing the surface roughness Sa from 7.16 to 11.91 μm to 1.63–1.95 μm.

The structure of prepared OVCS was characterized using FTIR. Thermogravimetric analysis suggested that the synthesized OVCS compound exhibited good thermal stability at the temperature below 200 °C. Weigh loss results indicated that OVCS compound acted as an effective corrosion inhibitor and the maximum inhibitory efficiency was up to 93.99 % at the concentration of 1000 mg/L.

The adsorption of OVCS compound onto mild steel follows Langmuir adsorption isotherm.

While chromatography coupled with mass spectrometry (MS) remains the gold standard in world anti-doping agency (WADA) accredited laboratories, its logistical and economic constraints limit the scope and frequency of testing, creating a significant detection gap. This gap highlights an urgent need for analytical platforms that are rapid, cost-effective, and adaptable for high-throughput screening and on-site testing. This review critically examines capillary electrophoresis coupled with electrochemical detection (CE-EC) as a powerful and versatile platform poised to fill this specific need. This review posits that CE-EC's primary role is not to replace the confirmatory power of MS, but to act as a vital complementary technology. This review provides a comprehensive analysis of technological advances that have enhanced CE-EC performance, including nanomaterial-modified electrodes and molecularly imprinted polymers for superior sensitivity, miniaturization into lab-on-a-chip formats for high-throughput analysis, and advanced detection modalities such as pulsed amperometric detection and capacitively coupled contactless conductivity detection. Concurrently, this review addresses the core challenges that have hindered its adoption, including the debate over sensitivity relative to MS, matrix effects in biological samples, and the need for robust, validated methods. By presenting evidence from recent literature, this review delineates the specific contexts in which CE-EC is a viable platform. Finally, this review explores future directions, focusing on portable, on-site CE-EC devices that could revolutionize anti-doping strategies by shifting the paradigm from centralized detection to widespread, real-time deterrence.</div></div>","PeriodicalId":13872,"journal":{"name":"International Journal of Electrochemical Science","volume":"20 12","pages":"Article 101229"},"PeriodicalIF":2.4,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145525957","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}
