Here we apply time-lapse imaging in a scanning electron microscope to study bismuth precipitation and coarsening at room temperature on the polished surface of Sn-2.25-0.5Ag-6Bi ball grid array solder joints after thermal cycling. It is shown that (Bi) precipitates on the surface within 2 h after polishing and then coarsens by a combination of Ostwald ripening, coalescence ripening, and competition between two orientation relationships. Time-lapse imaging revealed that coalescence causes an increase in the local bismuth particle size and the formation of anomalously large (Bi) particles. The accumulation of bismuth on the polished surface increases far beyond the equilibrium volume fraction for this alloy. The bismuth particle size distributions are significantly wider than expected from Lifshitz-Slyozov-Wagner (LSW) theory, that assumes only Ostwald ripening, which is shown to be because coalescence creates anomalously large particles. This study shows the important role of bismuth precipitate coalescence within the coarsening mechanism in Sn-2.25-0.5Ag-6Bi solder joints.","PeriodicalId":626,"journal":{"name":"Journal of Electronic Materials","volume":"54 4","pages":"2657-2671"},"PeriodicalIF":2.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11903617/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143646868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This method overcomes several limitations of traditional complex non-ideal curve fitting, which often results in inaccurate peak detection and full width at half maximum (FWHM) extraction. These complex non-ideal rocking curves arise in cases where additional features are present, such as peak splitting and multiple peaks. The application of the method also avoids the need for curve fitting and time-consuming calculations, allowing the extraction of peak widths at various normalized height-intensities (FWxM) and revealing extra information about defects. By analysing the broadening and peak position of the rocking curves for different defects, RC-XRDI provides insights into the nature and distribution of these defects within the material. Applied to RC-XRDI of a 4H-SiC 10 μm-thick homo-epitaxial layer on a substrate, the CII method was used to detect shifts in peak position and generate maps of full width at 1%, 10%, and 50% of maximum intensity, offering a detailed view of defect-induced broadening. Our results demonstrate that the CII method provides improved accuracy and requires fewer computations compared to curve-fitting techniques, making it particularly useful where precise defect characterization is critical. Moreover, background intensity was detected pixel-by-pixel using cubic smoothing splines, and the CII method provided robust validation for the precision of this background detection.","PeriodicalId":626,"journal":{"name":"Journal of Electronic Materials","volume":"54 7","pages":"5075-5086"},"PeriodicalIF":2.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12145299/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144257061","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the potential for organic dye degradation to be used as a rapid and efficient screening tool to detect the magnetoelectric effect of MENPs, and how the results of such a test mirror the antiproliferative effect of said nanoparticles. Trypan blue was selected as an azo dye to test for dye degradation. Vials of the dye were treated with CoFe2O4@BaTiO3 core-shell MENPs of varying characteristics, both with and without concurrent 1-kHz 250-Oe magnetic stimulation. Dye degradation was measured using ultraviolet (UV)-vis spectroscopy. Dye degradation efficacy varied with varying nanoparticle synthesis parameters. As controls, nanoparticles of the same composition, but with an insignificant magnetoelectric effect, were used. SKOV-3 ovarian cancer cells were then treated with the same nanoparticles, and viability was measured with an adenosine triphosphate (ATP) assay. These measurements show a decrease in cell viability up to 60.3% of control (p = 0.0052), which mirrored the efficacy of dye degradation of up to 69.8% (p = 0.0037) in each of the particle variants, demonstrating the value of azo dye degradation as a simple screening test for MENPs, and showing the potential of MENPs used as wirelessly controlled nanodevices to allow targeted electric field-based treatments.","PeriodicalId":626,"journal":{"name":"Journal of Electronic Materials","volume":"54 7","pages":"5529-5538"},"PeriodicalIF":2.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12145325/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144257062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the construction of nanostructures by the in situ method is still challenging. In this work, nanorod-assembled SnWO4 was fabricated directly on interdigital electrodes by a one-step aerosol-assisted chemical vapor deposition method. The xylene gas sensor was developed, featuring low detection limits and fast response. Under the operating temperature of 350°C, the detection limit of the SnWO4 sensor for xylene reaches a minimal level of 10 ppb. Meanwhile, the sensor exhibits excellent performance in response time, providing a rapid response of 2 s to 100 ppm xylene. Apart from this, the sensor also exhibits good selectivity. Among various volatile organic compound gases of the same 100 ppm at 350°C, the sensor’s response to xylene (484%) is 3.6 times that of toluene and 5.3 times that of benzene. The excellent gas-sensing performance is primarily due to the unique structural properties of nanorod-assembled SnWO4.

In order to study the noise problem of filter capacitors, it is necessary to begin with an analysis of the vibration mechanism that causes the noise. The primary cause of capacitor vibration is the generation of an alternating electric field in the insulating medium by the application of an AC voltage to the plates. This electric field exerts a force on the conductor, resulting in irregular vibrations and the production of noise. Current research does not consider the influence of the residual charge of the dielectric film and the internal insulating material on its internal vibration. This article therefore first conducts a theoretical analysis of the internal force of the filter capacitor, and then uses COMSOL simulation software to establish the multilayer structure of the capacitor core. The stress calculation model for the dielectric and aluminum foil layers explores and summarizes the influence of uneven residual charges and internal insulating materials on the stress of the capacitor core when it is in the alternating current (AC) and direct current (DC) mixed excitation state, by setting different residual charge distributions. The findings indicate that the residual charge of the dielectric film within the filter capacitor and the internal insulating material exerts a significant influence on its force under the influence of the electric field.
