We have demonstrated a simple and convenient chemical solution deposition method to synthesize Gd doped BiFeO₃ nanoparticles. Bi_1 − xGd_xFeO₃ (BGFO) nanoparticles are synthesized by modified Pechini method. Rietveld refinement of X-ray diffraction data confirmed a rhombohedral R3c crystal structure for all compositions. SEM analysis revealed highly crystalline nanoparticles with a decreasing average particle size from 346 nm to 180 nm as Gd concentration increased. Optical studies showed that Gd substitution reduced the band gap from 2.0 eV to 1.87 eV, attributed to lattice distortion and defect-induced sub-bands. There is secondary band gap is also observed around 1.42 eV. Photoluminescence (PL) studies indicated blue emission around 460 nm and orange emissions at 603 nm with PL intensity decreasing upon Gd doping. Commission Internationale de l’Eclairage (CIE) chromatic coordinates and color-correlated temperature were also determined for the prepared nanophosphor. Photovoltaic behavior is obtained in spin coated Bi_0.98Gd_0.02FeO₃ thin films. The incorporation of hole transport layer (P3HT) and electron transport layers (ZnO) significantly improved device performance, increasing J_sc from 0.70 mA/cm² to 3.18 mA/cm², V_oc from 0.17 V to 0.504 V and 94% increase in device efficiency. The findings showed that the optimized nanoparticles and thin films could generate a lot of interest for application in blue-orange LED and as semiconducting photoactive layer materials in solar cells.</p></div>","PeriodicalId":473,"journal":{"name":"Applied Physics A","volume":"131 6","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144135452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the rare gas mass spectrometer (RGMS) represents the current state-of-the-art for krypton detection in the field, we are developing a fully automated system (Auto-RGMS) to overcome the limitations of its manual operation. Auto-RGMS incorporates a robust control system for rapid measurements and minimized systematic uncertainties. A primary goal is to reach detection limits in the low parts-per-quadrillion (ppq) range for natural krypton by improving the chromatography stage to enhance the separation of krypton from xenon. Investigations into various adsorbent materials identified two candidates. HayeSep Q offers a 12-fold improvement in chromatographic resolution for xenon/krypton separation compared to the previously used adsorbent. Alternatively, HayeSep D provides a more limited improvement in resolution while allowing a higher measurement frequency because of its moderate retention-induced contamination after each measurement. By automating krypton assays and achieving ppq sensitivity, Auto-RGMS will be an indispensable tool for next-generation detectors, maximizing their scientific potential.</p></div>","PeriodicalId":788,"journal":{"name":"The European Physical Journal C","volume":"85 5","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1140/epjc/s10052-025-14262-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144140250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is a conspiracy responsible for a relative simplicity of the Macdonald polynomials and of the Noumi–Shirashi functions, and it is further continued to all integer DIM rays. Still, factorization is only partial, moreover, there are different branches and abrupt jumps between them. We explain this feature of Cramer’s rule in an example of a matrix that defines BAF and exhibits a non-analytical dependence on parameters.

For the first time, we report transport coefficients for Si⁺(²P) across a wide range of reduced fields (10–1000 Td) and temperatures (100–500 K), achieving uncertainties of &lt; 3% (low T) and &lt; 5% (high T).

Conventional techniques for optimizing nanoparticle structures are significantly expensive in computation and have some restrictions when exploring a broad range of design possibilities. To overcome these challenges, we used a policy-based RL model that learns how to arrange atoms on a canvas to minimize the potential energy of the nanocluster, like an actor–critic model. The agent works under a reward function based on the molecule’s energy, systematically positioning atoms on a canvas until it reaches convergence. The performance and evaluation of our RL model are assessed by local optimization techniques, specifically the BFGS optimization algorithm and simulated annealing. We conclude that the RL method is effective for identifying the configuration of Au₁₃ nanoparticles and achieving a stable and low-energy icosahedral structure.
