Although they are currently playing crucial roles in applications such as mobile communication, space-to-ground communication, and the Internet of Thing, there are significantly stringent and challenging requirements demanded for their rapid and successful applications. Compared with conventionally adopted low-temperature co-fired ceramics, integrated passive device filters, and dielectric filters, acoustic wave filters have been regarded as the competitive choice, mainly attributed to their wide bandwidth, small size, and low insertion loss. This paper reviews the advances and outlines future perspectives of high frequency acoustic wave devices for RF communication, focusing on several critical issues including bandwidth, roll-off, frequency, power-handling, insertion loss, out-of-band rejection, tunability, and size/package. It is focused mainly on the extreme performance breakthroughs of RF acoustic wave filter, e.g., how to achieve acoustic devices with operating frequency above 8 GHz, bandwidth around 1 GHz, and quality factor exceeding 2000. Various principles, strategies, and technologies for achieving the superior performance of super-high frequency RF filters are discussed, e.g., applying advanced materials such as scandium-doped AlN or single crystals of AlN and LiNbO3, creating new topology structures such as hybrid filters, and generating new types of vibration modes of acoustic waves.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"94 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145209784","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}

EVs demonstrate the capacity to target specific cells within organs, even requiring blood–tissue transition. The protein corona significantly influences EV availability and cargo delivery, with biomolecules residing both within and conjugated to the EV membrane. Furthermore, embedding EVs within biomaterials such as hydrogels, scaffolds, and nanofibers can enhance their stability, targeting specificity, and therapeutic potential. By addressing cargo loading and cell/tissue-specific targeting, EVs offer a novel therapeutic strategy for various diseases, including cancer, autoimmune disorders, and neurodegenerative diseases. Furthermore, EVs show promise as vaccination tools, delivering messenger RNA and proteins of various pathogens.

LGO's high-dielectric constant modulates PVDF-HFP crystallization into disordered amorphous domains, reducing interfacial resistance and enhancing exchange current density. Simultaneously, LGO promotes LiTFSI dissociation via dipole interactions while anchoring SN molecules, suppressing migration and side reactions. The optimized electrolyte achieves an ionic conductivity of 1.24 × 10−3 S·cm−1, a transference number of 0.67, an activation energy of 0.13 eV, and a critical current density of 0.8 mA·cm−2 at 45 °C.

Intuitively, Weyl fermions with opposite chirality, under the stimulus of parallel E and B, will have different chemical potentials that give rise to an extra current, whose role is like a chiral battery in solids. However, up until now, the experimental evidence for the chiral magnetic effect is the negative longitudinal magnetoresistance, rather than a chiral electric source. Here, different from previous reports, we observed a giant chiral magnetic effect evidenced by “negative” resistance and corresponding voltage–current curves located in the second-fourth quadrant in the type-II Weyl semimetal WP2+δ. These phenomena occur under the following conditions: the misalignment angle between B and E is smaller than 20°, the temperature is below 40 K, the externally applied electrical current is less than 50 mA, and the magnetic field is larger than 3 T. Phenomenologically, based on the macroscopic Chern–Simons–Maxwell equation, this giant chiral magnetic effect observed in WP2+δ is attributed to the chirality of Weyl fermions possessing a two-order longer coherent time than the Drude transport relaxation time. Our findings provide evidence of the giant chiral-magnetic/chiral-battery effect in Weyl semimetals.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"22 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145133845","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}

While Ga2O3 exhibits promising material characteristics for applications in harsh environments, its commercial viability remains under debate, particularly when compared to materials such as aluminum nitride (AlN) and diamond, which possess superior intrinsic properties. This perspective addresses the critical challenges that currently impede the widespread commercialization of Ga2O3-based devices. These challenges include a relatively immature technology base, the difficulty in achieving stable p-type conductivity, inherently low thermal conductivity, the presence of crystallographic defects (nano- and micro-voids), and elevated fabrication costs, all of which negatively impact device reliability and scalability. Mitigation strategies, such as heterojunction implementation, the development of thermal management solutions such as wafer bonding, and defect passivation approaches, are also under investigation. The near-term feasibility of commercially viable Ga2O3-based power electronic devices is a central focus of this discussion. The current status is that Ga2O3 development is far advanced relative to either diamond or especially AlN power electronics but is hampered by lack of a broad base of substrate vendors and a compelling vision for device implementations that provide sufficient improvement over SiC power devices. There are strong geographic differences in device focus, with China prioritizing implementation in grid applications while the United States/Europe appear to consider Ga2O3 devices more for defense and aerospace applications.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"17 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145133773","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}

Traditional approaches to catalyst development for H2 production, such as electrochemical catalysis (EC), photoelectrochemical catalysis (PEC), and photocatalysis (PC), have predominantly relied on empirical, trial-and-error methods. While significant progress has been made, these methods are time-consuming, costly, and limited by the complexity of multicomponent catalysts and reaction systems. In recent years, artificial intelligence (AI) and machine learning (ML) have emerged as transformative tools for accelerating catalyst discovery and optimization. AI-driven approaches enable high-throughput screening of materials, prediction of catalyst performance, and real-time reaction mechanisms, offering a more efficient alternative to conventional experimentation. This review examines the current state of catalyst development for green H2 production, highlighting the role of AI in optimizing hydrogen evolution and oxygen evolution reactions (HER/OER).

Such explorations are pursued in the framework of femtosecond optical excitation with THz probes wherein either negative or positive photoconductivity manifests in metallic and insulating states, respectively. Co-existence of both states is highly desired but rarely observed. Here, a strategy is devised exploiting crystalline transport anisotropy and hetero-epitaxy in a multi-band nickelate to demonstrate switching of the positive to the negative sign of photoconductivity on a sub-picosecond timescale. This combines with a profound anisotropy of THz photoconductivity in unconventional (111) epitaxial films having preferential arrangement of oxygen vacancies along selective crystal axes—a framework that reversibly modulates the anisotropy of negative THz photoconductivity using oxygen content as a control parameter, and corroborated by theoretical calculations. Thus, ultrafast switching between negative, positive, and zero photoconductive states in timescales of a few picoseconds at room temperature, as demonstrated in this study, holds a remarkable prospect for creating multiple channels of information processing. A proof-of-concept experiment to utilize these photo-controlled states is proposed for a three-state THz communication system, which would transmit a larger volume of information vis-a-vis that of a binary communication system.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"190 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145116368","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}

Using three nonlinear optical cationic chromophores with different interionic assembly types, each combined with three molecular anions featuring different substituents (non-polar methyl or polar chloro and bromo groups), we investigated nine ionic crystals, including four reported here for the first time. The crystal members within each isomorphic crystal family show nearly identical crystal structures (i.e., isomorphic crystal structures), all of them achieving top-level macroscopic second-order optical nonlinearity and efficient ultrabroad THz wave generation capabilities. Remarkably, their physical (and terahertz) properties within each isomorphic crystal family differ dramatically according to a certain order of the introduced anions, and this ordering trend persists across all three isomorphic crystal families. These results provide a crucial advancement in the design and prediction of macroscopic properties in ionic organic THz and nonlinear optical crystals, marking an important step toward rational crystal design exhibiting enhanced physical properties.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"82 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145116369","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}
