The polymer-ceramic composites are fabricated by varying the composition of the BFO as a filler material ranging 5, 10, 15, 20, 25, 30, and 40 wt% into the PVDF-HFP polymer matrix. We have investigated the effect of BFO loading on the structural, morphological, spectroscopic, and dielectric properties by different characterization techniques. X-ray diffraction analysis indicates the presence of non-polar α- and polar β- phases of PVDF-HFP in the composites. Scanning electron microscope studies revealed the spherulite morphology and homogenous dispersion of BFO particles. The addition of BFO filler in PVDF-HFP matrix at various percentages has been studied to improve the polar -phase of PVDF-HFP which may enhance ferroelectric properties. The dielectric studies at room temperature showed an increase in dielectric constant value from 9.5 (pure PVDF-HFP) to 21.08 (30% loaded BFO) at 100Hz. It is also evident from the Fourier Transform- Infrared (FT-IR) spectra, that a maximum of 75.24% of β-fraction is observed for 30% loaded BFO composition. The enhanced properties of the fabricated materials suggest that they may be useful for polymer-ceramic capacitor applications. The results are discussed in detail.","PeriodicalId":504734,"journal":{"name":"ECS Journal of Solid State Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140713759","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}

Also, when varying the concentration of NaOH, a similar film thickness was obtained through a cross-section of the FESEM images.

To attain desirable application performance of color converters in laser lighting, the excitation mode must be selected carefully. In this work, to understand the effect of the excitation mode on the performance of color converters, a detailed study was conducted on the heat dispersion, luminescence, and color quality of Al2O3-YAG:Ce phosphor ceramics in both transmissive and reflective modes. The relationship between ceramic porosity and scattering performance has also been analyzed by studying the beam expansion ratio. The results demonstrate that the phosphor ceramics in reflective mode exhibit superior heat dissipation capabilities and can withstand higher power laser excitation compared to the transmissive mode, while the light uniformity is relatively poorer due to the specular reflection. Therefore, in situations where a uniform light is not necessary, reflective color converters are more suitable for achieving superior luminance and luminous efficacy. Finally, a laser-driven white light device with a luminous flux of 1206 lm, a luminous efficacy of 241.2 lm/W, and a CCT of 5749 K has been realized using Al2O3-YAG:Ce phosphor ceramic in reflective mode, which can be applied for automotive headlights.","PeriodicalId":504734,"journal":{"name":"ECS Journal of Solid State Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140718099","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}

Furthermore, corrosion can pose serious safety risks that result in casualties which makes minimizing the effect of corrosion a great challenge. Traditional solutions like inhibitors, design modification, and paints are available to prevent corrosion but have many limitations, such as cost, durability, stability issues, and general inefficiency. In this context, a nanostructured superhydrophobic coating (SH) is gaining attention due to its corrosion prevention efficiency and other broad industrial applications. The nano air pockets exhibit a high contact angle due to their unique combination of elevated surface roughness, distinctive nanostructure, and reduced surface energy. This reduces the surface area of contact between the corrosive substance and water droplet and the metal surface, leading to improved efficiency in resisting corrosion.In this paper, the recent electrodeposition to develop corrosion-resistant SH coatings on copper substrates and compression with other metals with their physical, chemical, and thermal stabilities are discussed.","PeriodicalId":504734,"journal":{"name":"ECS Journal of Solid State Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140732069","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}
