This analysis involves the systematic development of interatomic pair potentials and the derivation of computational phase diagrams in the feature space of corresponding potential profiles. We focus on the following key components of interaction model: the reach distance of atomic interactions and perturbative long-range interactions reminiscent of Friedel oscillations which often lead to long-range interaction decay in crystalline materials. The computational experiments reveal that the perturbative interactions reflecting atomic local structures in CP polytypes, essentially diversify the polytypism in the phase diagrams. Using the pure La system with the 4H ground state, we also provide detailed procedures for creating practical pair potentials that approximately reproduce the energetics and physical properties deduced through the first-principles calculations.\u0000 Graphical abstract","PeriodicalId":19015,"journal":{"name":"MRS Advances","volume":"8 37","pages":""},"PeriodicalIF":0.8,"publicationDate":"2024-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139381334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The amount of Cs sorption was slightly lower for Mg-containing C–S–H than for C–S–H, because Mg leads to a decrease in sorption sites by facilitating the polymerization of silicate chains. However, the apparent sorption distribution coefficient Kd of Cs on C–S–H with a Ca/Si molar ratio of 0.8 and Mg contents up to 20% was estimated to be 3.4–6.1 mL/g. Furthermore, the amount of Cs sorption was not decreased by the presence of Ba. The apparent Kd obtained in this study was about 10 times higher than that conventionally estimated for host rocks in the plutonic repository, indicating that C–S–H retains the effect of Cs immobilization even when it contains Mg.\u0000 Graphical abstract","PeriodicalId":19015,"journal":{"name":"MRS Advances","volume":"1 6","pages":""},"PeriodicalIF":0.8,"publicationDate":"2024-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139381188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using smartphones as handheld visual colorimetric analysis devices and sample managers with novel flexible materials raises challenges not present when using rigid materials and better-controlled settings. For instance, accurately finding where analytes are is crucial to a correct analysis. This work has used deformed 96-wells plates as a model of devices that may be used in the field in combination with smartphone applications as colorimetric devices. An algorithm based on the application of the Hough transform followed by an interpolation is developed and tested with plate images that have been deformed in a controlled fashion. The procedure accurately detects the wells in all images of the test sets.

The functional groups of the crystal were identified using the FTIR and FT-Raman spectra. UV–Vis optical studies show UV cutoff wavelength at 221.6 nm, and the bandgap of the grown crystal was estimated at 4.87 eV using the Taucs’ plot. Photoluminescence spectra exhibited violet and red emissions. A high dielectric constant was received at a low frequency. The TG/DTA curve shows that the grown crystal was stable up to 125.59 °C. The Kurtz-Perry powder technique was applied to confirm the Second Harmonic Generation’s nature. By using the agar diffusion method, the antibacterial property of the grown 4B2MBN crystal was determined.
