Internal Friction (IF) spectra and anelastic modulus parameters were obtained in a vibrating reed apparatus between the temperatures of 100 K and 500°K (–173 °C and 227 °C) at a resonant mode frequency of 10<sup>3</sup> Hz. The thermal treatments resulted in distinct microstructural evolution, ranging from the low-defect, high-crystallinity state of the annealed samples to a highly defective structure characterized by nanograins and deformation twins in the quenched material. Crucially, the normalizing/quenched sample exhibited the highest amplitude IF peaks (e.g., 350°K). These prominent peaks are attributed to energy dissipation at high-energy grain boundaries and complex dislocation-point defect interactions. Microstructural findings were obtained using transmission electron microscopy (TEM), which identified the presence of dislocations and nanograins. Hasiguti and Bordoni peaks were identified in the IF spectra. The findings establish a methodology for engineers to tailor the dynamic damping capacity and stiffness of CP-Ti for applications requiring stable performance under dynamic loads and cryogenic environments.</div></div>","PeriodicalId":21042,"journal":{"name":"Results in Physics","volume":"82 ","pages":"Article 108600"},"PeriodicalIF":4.6,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147423833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is observed that the equilateral triangular nanoparticle arrangement provides multiple intense resonance channels with giant near-field enhancement at the three hot spots, fulfilling the single-molecule detection criteria, which makes it superior with respect to noble metal counterparts. The operating mechanism of the device is discussed based on the spherical multipoles, quantitatively illustrated by the normal electric field on the nanoparticle surface. The generated resonances can be reconfigured by applying different chemical potentials to the graphene shells. Furthermore, thanks to the wideband resonance excitation in the graphene material, the design can be extended to devices with other geometrical dimensions, suggesting the applicability of the sensor for a wide range of analyte detection. Importantly, the resonance generation is susceptible to geometrical symmetry, such that by opening the equilateral triangle vertex, the number of observed resonances increases. The multi-channel performance of the device can be employed for the precise detection of the mixture of the analytes with more certainty since the multiple frequencies and hot-spots increase respectively the chance of experiment double-checking and the molecule binding to the hot spot.</div></div>","PeriodicalId":21042,"journal":{"name":"Results in Physics","volume":"82 ","pages":"Article 108611"},"PeriodicalIF":4.6,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147422324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Within the various types of beams that can be produced with these devices, linearly polarized structured polarization beams offer unique properties that are advantageous for applications in fields such as microscopy, photoalignment, optical trapping, and communications. Generating purely linearly polarized structured beams is very challenging and requires a good characterization of the PA-LCoS. In this study, we apply Stokes polarimetric techniques twice: first to characterize the 2D retardance, and second to verify the fidelity of the generated structured light. We validate our approach by evaluating and compensating for spatial inhomogeneities for uniform wavefronts. Then, a wide variety of linearly polarized structured light beams are generated and metrologically evaluated to learn the uncertainty expected as a function of the complexity of the design. This approach not only enhances the stability and uniformity of the output beams but also broadens the potential for PA-LCoS SLMs in advanced optical applications.</div></div>","PeriodicalId":21042,"journal":{"name":"Results in Physics","volume":"82 ","pages":"Article 108604"},"PeriodicalIF":4.6,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147423834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
