Theoretical Investigation of Quantum Size Effect on the Electronic Structure and Photoelectric Properties for Graphdiyne Nanotubes.

In this paper, the electronic structure and photoelectric properties of graphdiyne nanotubes with armchair (A-GDYNT) and zigzag (Z-GDYNT) types have been studied. Calculations show that as n decreases, the divergence in gap values between (n)-A-GDYNT and (n)-Z-GDYNT increases. This is mainly attributed to the edge effect arising from their different boundaries.

A Center Drive Frequency Differential EIT Method for Monitoring of Tumor Ablation.

Monitoring and evaluating tumor ablation is a critical step in the treatment process.

Precision Molecular Engineering of Alternating Donor-Acceptor Cycloparaphenylenes: Multidimensional Optoelectronic Response and Chirality Modulation via Polarization-Driven Charge Transfer.

In this study, three alternating donor-acceptor (D-A) type [12]cycloparaphenylene ([12]CPP) derivatives ([12]CPP 1a, 2a, and 3a) were designed through precise molecular engineering, and their multidimensional photophysical responses and chiroptical properties were systematically investigated.

Parameter Identification and Transition Process Online Calibration Method of Pulsed Eddy Current Receiving Coil Based on Underdamped Dynamic Response Characteristics.

In order to solve the problem that the system parameters will be offset during the detection process of the pulsed eddy current receiving coil, this paper first analyzes the response signal of the receiving system and the deconvolution process of the response signal, and discusses the influence of various system parameters on the deconvolution accuracy. A method is proposed to change the system response characteristics and apply a step signal through the excitation coil to realize parameter identification through the response of the receiving coil system. The error of feature extraction under the change in each parameter is discussed, and the influence of increasing the matching resistance and switching the capacitor in parallel on the identification accuracy is analyzed and compared.

Multi-Modal Joint Pulsed Eddy Current Sensor Signal Denoising Method Integrating Inductive Disturbance Mechanism.

Pulsed eddy current (PEC) testing technology has been widely used in the field of non-destructive testing of metal grounding structures due to its wide-band excitation and response characteristics.

Dispersed Graphene Nanosheets Enhance Piezoelectricity of Poly (L-lactic acid) Nanofibrous Scaffold to Promote Bone Defect Repair.

The reconstruction of a localized electrical microenvironment at the defect site is considered an effective strategy to promote bone regeneration by mimicking the electrophysiological properties of natural bone tissue. Nano-piezoelectric materials have attracted significant attention in recent years due to their ability to generate electrical fields under external stress. However, this process can sometimes lead to negative consequences, such as inflammation at the lesion site.

ARM-Net: A Tri-Phase Integrated Network for Hyperspectral Image Compression.

Most current hyperspectral image compression methods rely on well-designed modules to capture image structural information and long-range dependencies. However, these modules tend to increase computational complexity exponentially with the number of bands, which limits their performance under constrained resources. To address these challenges, this paper proposes a novel triple-phase hybrid framework for hyperspectral image compression.

Self-driven piezotronic effect enhances the photocatalytic bactericidal activity of polyvinylidene fluoride/bismuth sulfide.

Exogenous carbon inputs alleviated salt-induced oxidative stress to cotton in salinized field by improving soil aggregate structure and microbial community.

High concentrations of salt ions in salinized soils not only destroy soil structure, but also inhibit crop growth. Straw and straw-derived biochar have great potential in improving soil structure, reducing soil salinity, improving soil environment, and alleviating salt stress. However, the effects and mechanisms of exogenous addition of different carbon sources on the aggregate structure and microbial community of soils with different salinization degrees in cotton fields as well as the antioxidant defense system of cotton are still unclear.

This approach minimizes the absorption of water-based softening agents by microcapillary channels of wood, enabling the controlled softening of the cell walls.

METTL3 improves the development of somatic cell nuclear transfer embryos through AURKB and H3S10ph in goats.

Developmental abnormalities are more common in somatic cell nuclear transfer (SCNT) embryos due to epigenetic barriers that occur during the maternal-to-zygotic transition (MZT). N6-methyladenosine (m6A) is an RNA epigenetic modification that plays a significant role in numerous biological processes. However, the relationship between m6A and SCNT embryonic development is largely unexplored.

Nanograting-Based Dynamic Structural Colors Using Heterogeneous Materials.

Dynamic structural colors can change in response to different environmental stimuli. This ability remains effective even when the size of the species responsible for the structural color is reduced to a few micrometers, providing a promising sensing mechanism for solving microenvironmental sensing problems in micro-robotics and microfluidics. However, the lack of dynamic structural colors that can encode rapidly, easily integrate, and accurately reflect changes in physical quantities hinders their use in microscale sensing applications.
