Applications extend to molecular isolation, diagnostic assays, and targeted drug delivery. Torques observed on superparamagnetic microbeads during cell experiments indicate spatial variations in the microbead properties. A high degree of internal magnetic structure complexity is revealed by nanoscale 3D imaging of superparamagnetic microbeads via soft X-ray laminography. Microbeads are found to have an uneven distribution of magnetic magnetite nanoparticles. The effects of this on the hydrodynamic behavior of the microbeads are analyzed by semi-numerical simulations using the laminography data. The calculated magnitudes of magnetic torque are consistent with the data from microbead transport experiments, involving fibroblast cells. By this, a structural basis for magnetic torques observed in experiments with superparamagnetic microbeads has been identified. Soft X-ray laminography is proven to be a powerful technique for revealing structural details important to lab-on-a-chip technologies. The findings indicate that magnetic microbeads deviate considerably from the theoretical model of uniform spheres.

Orbit-torque (OT) devices, such as OT-magnetic random-access memory and the orbital terahertz emitters, are being widely investigated for their low-power consumption and high stability in practical applications. However, the OT efficiency of these devices still requires further enhancement. In this review, we provide a concise introduction to the fundamental concepts in orbitronics, including the orbital Hall effect, orbital Rashba-Edelstein effect, and orbital-to-spin conversion coefficient. Furthermore, recent advances are highlighted for enhancing OT efficiency. These approaches can be broadly categorized into two intrinsic strategies: one focused on directly increasing orbital currents and torques, and the other aimed at improving the orbital-to-spin conversion coefficient. Additionally, we discuss current challenges and future directions in orbitronics. This review, along with the works discussed herein, aims to explore the potential applications of orbitronics in memory devices, logic computing, and terahertz emitters.","PeriodicalId":100035,"journal":{"name":"Advanced Physics Research","volume":"5 6","pages":""},"PeriodicalIF":2.8,"publicationDate":"2026-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/apxr.202500222","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148221948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite a comprehensive investigation effort invested by scientists and engineers, as of today, there is no useful device on sale made of VO2. The main cause is cracks induced by the large strain-stress developed upon cycling through IMT of clamped samples. Another weakness is the high sensitivity of VO2 to foreign cations and deviations from oxygen stoichiometry, which may induce multiple coexisting phases. To become useful in device technology, the phase diagram of doped VO2 should be adjusted to provide a wide range of temperatures below IMT in which the material is single-phase and not under strain or stress induced by the substrate and contacts.

The integration of freestanding transition metal oxide (TMO) membranes with two-dimensional van der Waals (2DvdW) materials presents a unique opportunity to explore novel interfacial phenomena, driven by their diverse crystal symmetries, bonding characteristics, and electronic correlations. These interactions can lead to the emergence of moiré periodicities, which fundamentally alter the physical properties of the hybrid systems. The interplay of differing symmetries and structural distortions in TMOs and ultrathin 2DvdW materials complicates the prediction of their collective behavior. The twisting of cubic and hexagonal lattices creates complex moiré patterns, while variations in energy scales and correlation strengths further enhance this complexity. Understanding the evolution of moiré periodicity in relation to symmetry and distortion is crucial but remains a significant experimental and theoretical challenge. This perspective explores the integration of 2D van der Waals layers with twisted transition metal oxide (TMO) membranes. We discuss key challenges for both material classes, emphasizing how symmetry, lattice distortions, and electronic correlations govern their structural and electronic behavior. We also examine limitations of current theoretical approaches and argue for the need to develop better multiscale computational methods to model and design these hybrid systems.","PeriodicalId":100035,"journal":{"name":"Advanced Physics Research","volume":"5 6","pages":""},"PeriodicalIF":2.8,"publicationDate":"2026-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/apxr.202500219","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148221748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the rational design of carbon dots (CDs) with well-defined multichannel emissive behavior remains challenging due to their complex structures and elusive luminescence mechanisms. In this work, photochromic CDs simultaneously exhibiting excitation-dependent room temperature phosphorescence (ED-RTP) were successfully prepared via a one-step microwave-assisted synthesis using 1,4,5,8-naphthalenetetracarboxylic acid and poly-L-lysine as precursors. The resulting N-CDs display pronounced and reversible photochromic behavior under 365 nm UV irradiation, along with long-lived green and orange–red afterglow emissions upon switching off excitation at 295 and 365 nm, respectively. These unique dual-mode luminescence features are mainly attributed to the in situ generation of naphthalimide radical species, along with emissive centers associated with both the carbon core state and the surface state. Benefiting from this dual-mode luminescence behavior, which integrates photochromism and ED-RTP, the N-CDs show great potential for high-level security applications, including multi-state anti-counterfeiting and multidimensional information encryption. Overall, this work offers a feasible strategy for constructing multifunctional phosphorescent CD-based materials and broadens the scope of intelligent light-responsive systems for advanced security identification and artificial-intelligence-related applications.","PeriodicalId":100035,"journal":{"name":"Advanced Physics Research","volume":"5 6","pages":""},"PeriodicalIF":2.8,"publicationDate":"2026-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/apxr.202500226","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148221794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While entanglement degradation in homogeneous systems is well-documented, the behavior of disparate-dimensional interfaces remains a critical challenge for the interoperability of future quantum networks. Using the negativity as a measure of entanglement, we analytically and numerically investigate how the spectral properties of the reservoir influence the system´s coherence. Our results reveal that the cut-off frequency ωc acts as a fundamental control parameter: at low frequencies, it triggers non-Markovian effects that effectively shield the system from entanglement sudden death, whereas high frequencies accelerate the transition to a purely dissipative regime. Furthermore, we demonstrate that strategic optimization of the coupling strength J and the entanglement parameter r can significantly enhance the robustness of hybrid correlations. The findings provide new methodological insights and practical guidelines for reservoir engineering, offering a framework to preserve quantum resources in high-dimensional hybrid architectures.","PeriodicalId":100035,"journal":{"name":"Advanced Physics Research","volume":"5 6","pages":""},"PeriodicalIF":2.8,"publicationDate":"2026-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/apxr.202500182","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148221947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
