This review critically examines the recent advancements in the development of BC-based sensors for the electrochemical determination of pharmaceuticals, pesticides, heavy metals, phenolic compounds, and microplastics. BC-based electrochemical sensors have emerged as a promising alternative due to their sustainability, cost-effectiveness, and excellent electrochemical properties. The unique physicochemical properties of BC, including its high surface area, porosity, and functional groups, contribute to its effectiveness as a sensor material. The review begins with an overview of the synthesis methods for BC, highlighting the activation strategies on its structural and electrochemical properties. Next, the functionalization of BC and its integration into electrochemical sensor platforms are explored. The performance of BC-based sensors is evaluated using electrochemical focusing on their sensitivity, selectivity, detection limits, and stability. Future directions for research are proposed, emphasizing the need for further optimization, miniaturization, and integration of BC-based sensors into portable and on-site analytical devices.","PeriodicalId":7802,"journal":{"name":"Analytical Sciences","volume":" ","pages":"715-735"},"PeriodicalIF":1.8,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143447691","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 CM-XRF, polycapillary lenses are placed in front of the X-ray tube and detector, and elemental information in the overlapping region of both focus points was obtained. Three-dimensional elemental distributions could be obtained by scanning a sample; the Ryugu sample was placed on an Al plate with one center, and the images of Fe, Ni, Cr, and Ca were obtained. The outlines of these elements were almost equivalent; however, as the energy of Ca Kα was low, its intensity in the elemental mapping was weak. Non-destructive TXRF measurements were performed to measure the trace elements in the Ryugu sample. We then performed quantitative analysis and determined the concentrations of trace elements such as Ga, Ge, and Se. The concentrations of these elements are higher than those in the CI chondrites. Therefore, we verified that the 3D elemental distributions and quantitative measurements in the Ryugu sample were performed without destruction.","PeriodicalId":7802,"journal":{"name":"Analytical Sciences","volume":" ","pages":"847-855"},"PeriodicalIF":1.8,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143960800","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}

Salbutamol is an inhalable drug which is used to treat symptoms of acute obstructive lungs disease and asthma. In this research, Raman spectroscopy technique has been utilized to determine the quality and quantity of solid dosage forms of salbutamol drug. Eight formulations of solid drug Salbutamol, combination of excipients and API, were prepared and analyzed. The Raman spectral features showed significant change in their intensities as directly related to variation in the concentration of formulation. Raman spectral results were further assessed by principal component analysis (PCA) and partial least squares regression analysis (PLSR) which are very potent chemometric tools for the quantitative and qualitative analyses of the pharmaceutical drugs. PCA was found to be useful in discriminating the acquired Raman spectra of various salbutamol drug formulations in solid forms of dosage. Furthermore, PLSR model developed for analyzing the quantitative relationship between different formulated solid dosages of salbutamol drug. The prediction of model and the prediction of an unknown drug formulation's concentration is performed by PLSR model. A value of 0.9079 mg was found to be for the root mean square error of cross-validation (RMSECV) and good fit regression R2 was found to be 0.998. Moreover, API concentration (w/w) of unknown formulation of the drug was found to be 8.90 mg (w/w) having actual concentration of 8 mg (w/w).","PeriodicalId":7802,"journal":{"name":"Analytical Sciences","volume":" ","pages":"705-713"},"PeriodicalIF":1.8,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143962294","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}

The significance of soil depth in SOC estimation underscores the importance of selecting appropriate sampling designs, soil depths, analytical methods, and baseline selection methods for accurate soil carbon stock estimation. Traditional methods such as wet digestion and dry combustion (DC) remain prevalent in routine laboratory analysis, with DC considered the standard reference method, surpassing wet digestion in accuracy and reliability. Recent advancements in spectroscopic techniques enable SOC measurement both in laboratory settings and in situ, even at greater depths. Aerial spectroscopy, which employs multispectral and hyperspectral sensors, unmanned aerial vehicles (UAVs), or satellites, facilitates surface SOC measurement. While the current precision levels of these techniques may be limited, forthcoming hyperspectral sensors with enhanced signal‒to‒noise ratios are expected to significantly increase the prediction accuracy. Furthermore, at the global level, satellite remote sensing techniques have considerable potential for SOC estimation. Regardless of whether traditional or novel approaches are utilized, the selection of SOC determination depends on available resources and research requirements, each of which plays a distinct role in soil carbon and climate research. This paper provides an overview of various scale-dependent techniques for measuring SOC in agricultural soil, along with its potential limitations.","PeriodicalId":7802,"journal":{"name":"Analytical Sciences","volume":" ","pages":"759-776"},"PeriodicalIF":1.8,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143603099","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}

We found that auto-generated radicals within a [Bmim][PF6]/[C16mim][PF6]/PBS reverse micelles (IL-RMs) and then the radicals were quantified in this study. For the radical confirmation, EPR spectroscopy with 5,5-dimethyl-1-pyrroline N-oxide (DMPO) free radical scavenger was carried out. A spectroscopic chemical probe of 1,1-diphenyl-2-picrylhydrazine (DPPHH) was employed to quantify the radicals in the IL-RM systems. The mechanism of the radical generation was also proposed. The DPPHH probe method is simple, rapid, and sensitive to quantify free radicals in the IL-RM systems. Finally, IL-RMs were successfully applied to degrade Rhodamine B (Rho-B) dye with low degradation cost, simple operation, short time consumption, and remarkable degradation effect. The results show a near 100% degradation rate for 10 μmol·L-1 Rho-B in the IL-RMs system with pH 7.4 PBS containing 1 mmol·L-1 chloroacetic acid as an aqueous phase.","PeriodicalId":7802,"journal":{"name":"Analytical Sciences","volume":" ","pages":"839-845"},"PeriodicalIF":1.8,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143668653","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}
