However, conventional approaches often face inherent limitations, such as susceptibility to electromagnetic interference, instability in humid or sweat-rich conditions, and restricted multifunctional integration. To overcome these challenges, we present a flexible sensor based on a multifunctional MXene/LIG composite structure. By combining surface-modified MXene with laser-induced graphene (LIG), we developed a robust conductive framework characterized by hierarchical porosity. Thanks to this innovative design, the sensor achieves exceptional multifunctional performance. It exhibits high electromagnetic shielding effectiveness of 31.5 dB through synergistic reflection and absorption, demonstrates strong hydrophobicity with a contact angle of 151.1°, and delivers enhanced thermal conductivity. These features enable accurate monitoring of operational movements in simulated cockpit environments while ensuring durable performance under complex aviation requirements. Moreover, this design strategy offers a novel pathway for advancing high-performance flexible sensors, opening new opportunities in wearable electronics, healthcare monitoring, and intelligent human-machine interaction systems.","PeriodicalId":10253,"journal":{"name":"Chinese Physics B","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147887035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among this class of materials, hexagonal MnTe stands out due to its high Néel temperature and giant spin splitting. However, a comprehensive understanding of its charge dynamics remains incomplete. Here, we employ infrared spectroscopy to investigate the charge dynamics of single crystalline MnTe. The low energy optical conductivity reveals a suppressed Drude response across all temperatures, consistent with the reported p-type doping as indicated by previous angle-resolved photoemission spectroscopy (ARPES) measurement. An indirect band gap of about 0.48 eV attributed to impurity-assisted transitions, and a direct gap of 1.60 eV are identified via the Tauc relation at 10 K. Moreover, we observe a subtle difference at around 1.44 eV in the optical conductivity between the antiferromagnetic and paramagnetic states, which might be linked to altermagnetism-related band splitting. Additionally, Fano line shape analysis of a phonon mode at around 135 cm −1 reveals appreciable coupling between the phonon and spin fluctuations near the Néel temperature. Our results provide key insights into the charge dynamics of MnTe, underscoring its rich physics beyond a conventional semiconductor.","PeriodicalId":10253,"journal":{"name":"Chinese Physics B","volume":"35 3","pages":"037801-037801"},"PeriodicalIF":0.0,"publicationDate":"2025-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147889973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A series of Yb 3+ , Ho 3+ :NBM single crystals doped with Li + , K + , and Ca 2+ ions were successfully grown using the Czochralski method. Their structural characteristics were analyzed through X-ray diffraction (XRD), transmission spectroscopy, and scanning electron microscopy (SEM), confirming a tetragonal crystal structure with space group I4 1 /a. Under 980 nm and 450 nm laser excitation, the crystals exhibited distinct UC emission profiles, with dominant red and green emissions, respectively. Tauc plot analysis indicated that Ca 2+ doping introduced donor levels within the crystal lattice, effectively narrowing the optical bandgap. Power-dependent luminescence studies revealed that both red and green UC emissions originated from two-photon excitation processes. Temperature-dependent photoluminescence measurements under both excitation wavelengths demonstrated that codoping with Li + , K + , and Ca 2+ significantly enhanced the thermal stability of the luminescent properties. Furthermore, variable-temperature fluorescence lifetime analyses showed that alkali and alkaline earth metal ion doping effectively mitigated the luminescence lifetimes. Overall, the incorporation of Li + , K + , and Ca 2+ ions was found to markedly improve both the UC luminescence intensity and thermal robustness of Yb 3+ , Ho 3+ :NBM single crystals, offering promising prospects for high-performance luminescent materials.","PeriodicalId":10253,"journal":{"name":"Chinese Physics B","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147884403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, MoS 2 and graphene — two widely studied 2D materials — were successfully assembled into vdW heterostructures via a convenient ultrasound-driven self-assembly approach. The morphology of the heterostructures was characterized by scanning electron microscopy (SEM), while their structural and compositional features were confirmed through x-ray diffraction (XRD), Raman spectroscopy, and x-ray photoelectron spectroscopy (XPS). Red-shifted Raman peaks and decreased binding energies in XPS spectra provided strong evidence of successful heterostructure formation. A three-stage assembly mechanism — comprising dispersion, assembly, and adjustment — is proposed, with acoustic cavitation playing a key role in driving the process.

In this study, a programmable electromagnetic valve is externally connected with the microfluidic chip featuring a conventional flow-focused structure. Different from the previous situation where only one droplet is generated by a single actuation of the electromagnetic valve, by precisely controlling the opening and closing of the valve, the continuous phase fluid exhibits periodic flow in the channel, and we realized the generation of a droplet group by a single actuation of the valve, and the number and volume of the droplets in each group can be regulated. Specifically, the number of large droplets in a droplet group is mainly determined by the opening time of the electromagnetic valve and the two-phase flow rate, and the number of small droplets is dominated by the valve closing time. The volume of individual droplets in a droplet group is largely dependent on the flow rate of the continuous phase. Our study extends the understanding of microfluidic droplet formation. It provides a feasible method for the efficient preparation of polydisperse droplets, which is important for microfluidic chip-based droplet control and has potential applications in industries related to microfluidic droplets.","PeriodicalId":10253,"journal":{"name":"Chinese Physics B","volume":"34 12","pages":"124702-124702"},"PeriodicalIF":0.0,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147917422","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}

However, enhancing both electrical conductivity and fracture toughness simultaneous is challenging. This study reports the synthesis of (Ti 0.2 W 0.2 Ta 0.2 Hf 0.2 Mo 0.2 )C-diamond composites with varying densities using high-pressure and high-temperature (HPHT) method. The carbides are uniformly dispersed in a titanium carbide matrix, forming conductive channels that reduce resistivity to 4.6 × 10 −7 Ω⋅m. These composite materials exhibit metallic conductivity with a superconducting transition at 8.5 K. Superconducting behavior may result from d–p orbital hybridization and electron–phonon coupling in transition metal carbides, such as TaC, Mo 2 C, and MoC. Optimizing intergranular bonding improves the fracture toughness without compromising hardness. The highest indentation toughness value is 10.1 ± 0.4 MPa⋅m 1/2 , a 130% increase compare to pure TiC. Enhanced toughness arises from transgranular and intergranular fracture modes, multiple crack bridging, and large-angle crack deflection, which dissipate fracture energy and inhibit crack propagation.
