While particle-size optimization is often considered critical for enhancing solar scattering, the role of microsphere diameter once a coating operates in the multiple-scattering regime remains unclear. Here, we characterize the radiative cooling performance of disordered, multiply scattering photonic glass coatings with diameters ranging from 2 to 8 μm, deposited on a highly reflective substrate. Despite measurable differences in microscopic scattering properties, both the spectral radiative response and the net cooling performance are robust to variations in particle diameter within the investigated range. Outdoor thermal measurements reveal nearly identical steady-state temperature reductions across the full size range. These results identify this robustness as a property of the complete coating–substrate architecture: in the solar range, multiple scattering and the reflective substrate act together to maintain high reflectance, while in the mid-infrared range, the response is dominated by the intrinsic Si–O absorption of the silica layer. This robustness enables microsphere size to be selected based on surface chemistry or processing constraints without compromising cooling performance.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"81 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149210864","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}

Maximum value of thermoelectric figure of merit (z{{T}_{{max }}} = 1.34) at 735 K was achieved for the unalloyed sample. It was established that doping (3d)-metals leads to a decrease (zT) due to a decrease in electrical conductivity and an increase in thermal conductivity. Experimental data show that with decreasing charge number (3d)-ion, an increase in the magnetic moment at the substitution position is observed. However, for the entire series of compositions, no significant increase in magneto-thermoEMF was detected. The calculations carried out within the framework of the density functional theory qualitatively reproduce the experimental data and confirm that the contribution of spin entropy, magnon drag and other spin-caloritron mechanisms to the thermoelectric properties in tetrahedrites with substitutions 3d-metals is insignificant.","PeriodicalId":604,"journal":{"name":"JETP Letters","volume":"124 5","pages":"373 - 379"},"PeriodicalIF":1.1,"publicationDate":"2026-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149214597","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}

To derive the relationship between the cross sections, a model of interaction with an additional non-nucleon channel is used, in which the relationship between the corresponding amplitudes is determined by the energy dependence of the non-nucleon component of the (NN)-system wavefunction. It is shown that the obtained cross section ratio is practically independent of the interaction model at excitation energies of the nucleon pair from 0 to 40–50 MeV. As an example, the ratios of total and differential cross sections of the reaction (pp to pn{{pi }^{ + }}) to the corresponding cross sections of (pp to d{{pi }^{ + }}) are considered.

Fluorescent diarylethene (DAE) photoswitches, with exceptional reversibility, thermal stability, fatigue resistance, and tunable photochromism, enable this approach by reversible switching between fluorescent “on” and dark “off” states, allowing neighboring molecules within the diffraction limit to be distinguished. Fluorescent DAE derivatives have recently garnered increasing attention as fluorescent labels for SRI applications, offering decisive advantages over conventional photoswitches. Despite considerable progress, a systematic review specifically addressing the application of DAEs in SRI remains absent. Herein, we present a comprehensive survey of fluorescent DAE photoswitches for SRI, centering on molecular design strategies and recent advances. We categorize these systems into four classes based on their activation modes and driving mechanisms: “turn‐on” fluorescent DAEs, “turn‐off” fluorescent DAEs, polymeric fluorescent DAEs, and visible‐light‐driven DAEs. For each category, we highlight representative structures, key design rationales, and imaging performance benchmarks. We conclude by identifying current challenges and outlining future perspectives, aiming to guide the rational development of next‐generation fluorescent DAE photoswitches for advanced super‐resolution bioimaging.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"10 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149208492","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}

Its chemical stability, strong piezoelectric properties, and biocompatibility have turned GaN into a crucial candidate for next‐generation microelectromechanical systems (MEMS), including sensors, resonators, and energy harvesters operating in harsh environments. However, GaN's transition from planar devices to 3D MEMS structures is limited by its hardness, brittleness, and chemical inertness. Conventional fabrication methods induce heat‐affected zones, lattice damage, and micro‐cracks, significantly reducing device yield and performance. This review presents a comprehensive analysis of ultrafast laser micro/nano processing as a transformative, non‐contact manufacturing paradigm to overcome these limitations. We first elucidate the fundamental mechanisms of laser–material interactions, distinguishing between picosecond (ps) and femtosecond (fs) regimes, with attention to non‐linear absorption, ionization dynamics, and non‐thermal ablation enabling submicron resolution with minimal collateral damage. We investigate laser methodologies including maskless direct writing, laser lift‐off (LLO), and laser‐induced periodic surface structures (LIPSS), highlighting their integration into high‐performance GaN MEMS devices for enhanced sensitivity. We explore hybrid integration with complementary metal‐oxide‐semiconductor (CMOS) technology and artificial intelligence (AI)‐driven optimization to address throughput challenges, offering pathways toward wafer‐scale manufacturing of next‐generation GaN MEMS.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"34 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149208463","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}

Here, we propose and experimentally demonstrate a cross‐scale integrated photonic convolver (CSIPC) that enables cross‐scale feature extraction through a single training process. Implemented on a hierarchically coupled finite‐impulse‐response (FIR) photonic chip, the CSIPC exploits the propagation of conjugate‐symmetric interference‐weight relations through the coupling network, together with the spatiotemporal interleaving induced by serial‐to‐parallel conversion. A single set of trained chip weights can be mapped at different output ports into a family of equivalent convolution kernels with distinct effective tap numbers and temporal intervals. By selecting the output port and tuning the input symbol rate, 2 × 4, 2 × 2, and 2 × 1 two‐dimensional convolution kernels can be realized on the same chip. We experimentally validate multifunctional cross‐scale image feature extraction and achieve a maximum single‐mode equivalent computing throughput of 0.276 TOPS. These results provide a route toward cross‐scale photonic convolution using a single device and a single training process, while improving functional integration density and enabling the reuse of trained weights and hardware resources.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"30 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149208462","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}
