“…It is often used in conjunction with other microscopic testing methods to determine the mineral composition of the sample. By combining EDS and SEM analysis methods, compared to traditional techniques such as XRD, testing objectives can be achieved at a lower cost and low mineral composition can be observed more easily [80].…”

Leaching in cement-based materials and dissolution in rocks are important problems in civil engineering. In the past century, concrete damage caused by leaching have occurred worldwide. And, rock dissolution is usually the main cause of karst rock erosions. This paper provides a review of the causes, influencing factors, and effects on engineering properties of dissolution of rocks and leaching of cement-based materials. The applied experimental methods for leaching and dissolution have been sorted out and discussed. In situ field experiments can be used to study dissolution under natural conditions, while the laboratory experiments can effectively shorten the experiment time length (by changing pH, temperature, pressure or other factors that affect the leaching or dissolution) to quickly investigate the mechanism of dissolution and leaching. Micro tests including XRD, SEM, EDS, and other testing methods can obtain the changes in material properties and microstructures under leaching and dissolution. In addition, with the advances in technologies and updated instruments, more and more new testing methods are being used. The factors affecting the leaching and dissolution include environmental factors, materials, and solvent parameters. The mechanisms and deterioration processes of leaching and dissolution varies according to the types of material and the compositions.

“…The chemical composition of the fundamental ash components (Na, P, S, K, Mn, Fe, Mg, Ca, Cr, Co, Cu, Ni, Zn, and Pb) may be easily identi ed using an analytical scanning electron microscope and the EDS-method (Gins et al 2018). A novel approach to qualitative mineral identi cation and quantitative measurement was devised using scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) (Liu et al 2021). EDX analytical technique can be used for elements such as calcium and potassium analysis in food samples such as fruits, vegetables and spices (Md Noh et al 2020).…”

For decades, indigenous people of rural regions have been consuming wild edible plants as food and medicines. Wild edible plants are neglected and underutilized food plants whose utilization is only restricted to a specific location. It is also referred as Future Smart Foods. Nutritional analysis can provide valuable insights into the potentiality of native wild edible plants as sustainable and nutritious food source. This study aims to analysis the proximate and elemental composition, and antioxidant activity of underutilized and neglected plants in Tripura. In our findings, relatively high carbohydrate, protein and fats content was observed in Oroxylum indicum (13.34±0.29), Trachyspermum roxburghianum (10.43±0.19) and Flacourtia indica (4.25±0.28) respectively. The highest Total energy was recorded in Flacourtia indica (107.97 Kcal). The highest moisture and ash content was observed in Alpinia nigra (94.95%) and Trachyspermum roxburghianum (42.16%) respectively. The quantitative concentration (Wt %) of six micronutrients (Mg, P, K, Ca, Fe and Cl) reveals that the highest was observed in potassium (K) i.e. 34.15% (34.15 mg/gm) in S. pennata. The free radical scavenging activity of the ethanolic extracts showed that L. leucocephala possessed high antioxidant activity (IC50 =125.4±1.78). The nutritional values may be helpful for these underutilized crops to encourage future conservation plans and assess the level of dietary supplement dependency of the local communities. Therefore by promoting the cultivation and consumption of underutilized crops, we can support local communities and accomplish sustainable development in food security.

“…For example, in the case of a rock, the distribution of an element at the sample surface might be related to the presence of a certain mineral. 6 The process of finding these relevant spectral ranges is typically performed in one of two ways. The most common is to use prior information on the sample composition and search for emission lines of elements we suspect to be present.…”

Laser-induced breakdown spectroscopy (LIBS) imaging has now a well-established position in the subject of spectral imaging, leveraging multi-element detection capabilities and fast acquisition rates to support applications both at academic and technological levels. In current applications, the standard processing pipeline to explore LIBS imaging data sets revolves around identifying an element that is suspected to exist within the sample and generating maps based on its characteristic emission lines. Such an approach requires some previous expert knowledge both on the technique and on the sample side, which hinders a wider and more transparent accessibility of the LIBS imaging technique by non-specialists. To address this issue, techniques based on visual analysis or peak finding algorithms are applied on the average or maximum spectrum, and may be employed for automatically identifying relevant spectral regions. Yet, maps containing relevant information may often be discarded due to low signal-to-noise ratios or interference with other elements. In this context, this work presents an agnostic processing pipeline based on a spatial information ratio metric that is computed in the Fourier space for each wavelength and that allows for the identification of relevant spectral ranges in LIBS. The results suggest a more robust and streamlined approach to feature extraction in LIBS imaging compared with traditional inspection of the spectra, which can introduce novel opportunities not only for spectral data analysis but also in the field of data compression.
