Summary: In this study, accurate measurements of thermal boundary resistance (R) of 2D material interfaces were conducted. It was found that, in addition to phonon transport, thermal resistance between nonequilibrium phonons in the 2D materials could also play a critical role. These findings provide important insights into heat dissipation in 2D material devices and highlight the significance of considering the influence of nonequilibrium phonons in device design.

Summary: The study shows that at graphene grain boundaries, backward scattering is more diffuse than forward scattering, supporting the hypothesis that separate specularity parameters are needed to describe transmitted and reflected phonons. This sheds new light on how surfaces and interfaces modify phonon transport within and between domains in nanostructured materials.

Summary: In this study, a theoretical model for phonon thermal boundary conductance across solid interfaces in the high temperature classical limit is derived using quasi-harmonic thermodynamics. The model takes into account the effects of phonon anharmonicity on energy density changes and shows good agreement with experimental and simulation results. This model has the potential to be applied in various applications to increase thermal conductance and mitigate temperature.

Summary: The Qingchengzi ore field is an important gold-polymetallic center of the North China Craton. The mechanical contrast between the schist and marble along lithological interfaces appears to be a major reason for stress localization under a compressional stress regime, concentrating mineralizing fluids along these interfaces. This has implications for understanding the structural controls of lithological interfaces on mineralization in other gold deposits of the region.

Summary: Amoebiasis is a parasitic infection caused by Entamoeba histolytica, transmitted through contact or ingestion of contaminated food or water. Traditional models assume homogeneous transmission, but heterogeneity is significant in disease dynamics. A fuzzy SEIR model is used to study equilibrium and reproductive number, and numerical simulation results show the effectiveness of the proposed NSFD method.

Summary: The present study aims to compare the differences between discontinuous models (DM) and continuous models (CM) in the analysis of seismicity in majestic masonry structures. The 'Santa Maria Annnuziata' church damaged after the Central Italy earthquake sequence in 2016 and 2017 is used as a case study. The effectiveness of the DM and CM models is assessed through nonlinear dynamic analysis of earthquake events and the models' response to a 7.8-magnitude earthquake in Turkey.

Summary: Safe social distance is crucial for preventing and treating droplet-transmitted viruses, but the currently used distance may not be suitable for all air environments. Calculating fluid dynamics is time-consuming, making it difficult to rapidly obtain the safe social distance. This study established a simple and effective numerical model and conducted simulations to investigate droplet motion in different air conditions. The results demonstrated the accuracy of the predicted data and provided recommendations for prevention and control based on common clinical cases.

Summary: Nano approaches can effectively enhance the thermoelectric figure of merit by introducing strong phonon scattering at heterogeneous interfaces, as demonstrated in Mg2Sn/Mg3Sb2 high-content nanocomposites in this study. This leads to a significantly reduced lattice thermal conductivity and ultimately achieving a high ZT value in the material. Various defects were also observed through microstructure characterization in both Mg3Sb2 phase and Mg2Sn phase.

Summary: Understanding the physical processes involved in interfacial heat transfer is crucial for interpreting thermometric measurements and optimizing heat dissipation in nanoelectronic devices based on TMD semiconductors. A phenomenological theory for modeling diffuse phonon transport at disordered interfaces was introduced in this study, with results suggesting that heat dissipation at the TMD-SiO2 interface is dominated by phonons scattered diffusely by the rough interface. Moreover, the electronic TBC contribution may also be significant even at low electron densities, potentially explaining variations in experimental TBC data.

Summary: Understanding the phonon-mediated heat dissipation between two-dimensional layered materials and hexagonal boron nitride substrates is crucial for the design and thermal management of nanoelectronic devices. A new elasticity-based theory is proposed to model this heat dissipation, providing insights into the effectiveness of h-BN compared to other common substrates. The study also compares the predictions of the stack model with more exact atomistic models, highlighting the role of flexural modes and anisotropic elastic properties in heat dissipation.
