In this study, we establish a novel approach based on the concept of <i>General Energy Behavior (GEB)</i> to reinterpret and unify fundamental thermodynamic principles. Here, while defining, supplementing and integrating all established materials regarding <i>Energy Structure Theory (EST)</i>, we introduce and formally define two universal laws of energy behavior: the <i>Preference Law</i>, which describes the system’s tendency to retain energy in non-dynamic forms, and the <i>Exchange Law</i>, which governs the interaction between independent and dependent components of non-dynamic energies. These GEB laws aim to unify aspects of the first and second laws of thermodynamics and offer a structured perspective for analyzing energy exchange processes in physical systems. We derive the corresponding mathematical formulations and validate them using a generalized application of Borchers’ remarks on the second law of thermodynamics. The results suggest that GEB laws may offer a useful theoretical basis for future efforts toward unifying physical principles.</p></div>","PeriodicalId":597,"journal":{"name":"International Journal of Theoretical Physics","volume":"64 10","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145256707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Herein, a hierarchical ceramic encapsulation strategy combining mesoporous silica (SiO2) confinement and zirconia (ZrO2) ceramic coating to achieve ultra‐stable CsPbBr3 NCs is proposed. The mesoporous SiO2 framework acts as a nanoreactor for spatially confined NCs growth, while atomic‐layer‐deposited ZrO2 seals residual micropores and forms a dense, impermeable shell via high‐temperature annealing (300–600 °C). Optimized composites (400 °C‐annealed) retain a high photoluminescence quantum yield (PLQY >85%) and demonstrate record stability: maintain 100% of their photoluminescence value after 720 h under “double‐85” (85 °C, 85% RH) conditions and >65% of initial PL intensity under high‐power laser excitation (200 mW mm−2, 450 nm) for 108 h. When integrated into laser‐driven white‐light devices, the device achieves an ultra‐wide color gamut (98% Rec. 2020, and 131% NTSC), surpassing state‐of‐the‐art perovskite‐based systems. This dual‐phase hierarchical ceramic encapsulation strategy not only overcome the stability bottleneck of perovskites but also unlocks their potential in high‐energy photonic technologies.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"50 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145254993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Semiconductor lasers have addressed these issues in the visible and infrared parts of the electromagnetic spectrum; but in the ultraviolet, they are just starting to see the light of day. Edge‐emitting semiconductor lasers are the only ones demonstrated under electrical injection in the deep‐ultraviolet (<280 nm) and they inherently suffer from poor beam qualities, multiple modes, and catastrophic optical damage to the mirror. The first deep‐UV photonic crystal surface‐emitting lasers are demonstrated here. The devices show single‐mode emission around 279 nm with less than 1 beam divergence. They require a specific design to overcome optical scattering and the low refractive index that otherwise prohibits a 2D standing optical field. The optically pumped deep‐ultraviolet photonic crystal surface‐emitting lasers offer drastically improved beam quality and provide an important step toward low‐divergent, watt‐class, electrically‐driven UV PCSELs.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"114 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145254994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

However, double white dwarfs (DWDs) have long been recognized as promising sources of gravitational waves, and upcoming detectors such as LISA will be able to observe these systems in abundance. Double white dwarfs are expected to be the dominant gravitational wave (GW) sources in parts of the LISA frequency range, making it crucial to understand their formation for future detections. The Milky Way contains many white dwarfs (WDs) in both the field and star clusters, promising a rich population of DWDs for LISA. However, the large number of sources may make it difficult to resolve individual binaries, and DWDs in the field and clusters often have similar properties, complicating the identification of their origins from GW signals alone. In this work, we focus on eccentric and tight DWDs, which cannot form in the field, but require dynamical interactions in dense clusters to increase their eccentricity after circularization through mass transfer phases and common-envelope evolution during binary evolution. These binaries may also form in three- and four-body dynamical interactions, whereby a DWD binary may directly form with high eccentricity and low separation. Our results show that we should expect eccentric and tight DWDs in clusters that can provide a meaningful GW signal; however, the number is low, with an upper limit of 10-15 in the MW. These can be used to independently obtain the distances of their host clusters.","PeriodicalId":8571,"journal":{"name":"Astronomy & Astrophysics","volume":"102 1","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145277453","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}
