We investigate the plasmonic analog of electromagnetically induced transparency (EIT) using two adjacent graphene-based Fabry-Perot (F-P) resonators side coupling to a nanoribbon waveguide. By the coupling mode theory in time and F-P resonant model, the destructive interference from the coupling of the two F-P resonators results in the EIT-like optical response. The induced peak and width of the transparency window can be dynamically manipulated by varying the coupling distance of the two resonators, and the transparent window is easily shifted by tuning the resonator length or the chemical potential of the graphene nanoribbon. In order to verify the characteristics of slow light, the group index profile is analyzed at different coupling distances. The proposed graphene-based EIT-like system could open up new opportunities for potential applications in plasmonic slow light and optical information buffering devices.

This study investigated the formation of characteristic aroma compounds in braised pork during electromagnetic cooking, focusing on the effect of added seasonings on lipid oxidation and the Maillard reaction. The accelerated lipid oxidation led to a rapid increase in the levels of most characteristic aldehydes, 1-octen-3-ol, and 2-pentylfuran during the temperature-rising stage (S0-S2) and the simmering stage (S3-S4) in braised pork. However, the addition of seasonings inhibited polyunsaturated fatty acid oxidation, reducing the levels of these lipid-derived aroma compounds during the sauce thickening stage (S5).

Shade stress alters soybean growth through transcriptomic changes and adaptive responses that optimize light capture and utilization, regulated by a phytohormonal network. This study examined the physiological, morphological, and molecular responses of Guru (shade-tolerant) and Heinong 53 (shade-sensitive) soybean cultivars under 0% (control), 30%, and 70% shade. Results revealed morphological responses where Heinong 53 exhibited greater plant height (52.

Hybrid artificial layer based on inorganic/polymer composite endows superior toughness and mechanical strength, which can achieve high stability of lithium metal anode. However, the large particle size and uneven distribution of inorganic fillers hinder the uniform flow of lithium ions across the membrane, making it difficult to achieve smooth lithium metal deposition/stripping. In this work, a chemical lithiation-induced defluorination strategy is proposed to engineer poly(vinylidene difluoride) (PVDF)-based artificial layers, enabling in situ incorporation of highly dispersed LiF nanofiller within the polymer matrix and precise control over the LiF content.

Recent advances in two-dimensional (2D) magnetic materials have promoted significant progress in low-dimensional magnetism and its technological applications. Among them, atomically thin chromium trihalides (CrX with X = Cl, Br, and I) are among the most studied 2D magnets due to their unique magnetic properties. In this work, we employ density functional theory calculations to investigate the mechanical and electronic properties of CrX monolayers in the presence of in-plane uniaxial strain.

Background: In catheter-based radiofrequency ablation (RFA), energy is delivered to heterogeneous thin-walled tissues to induce therapeutic heating. Variations in electrical and mechanical properties of tissue contents have a great effect on outcomes.
Purpose: The objective of this study is to develop models that replicate tissue heterogeneity and visualize ablation zones for effective evaluation and optimization.
