Summary: Free vibrations of orthotropic micro/nanoplates with nonclassical shape are investigated using the nonlocal elasticity theory. The Ritz method and R-function theory are used for constructing the system of coordinate functions. Linear frequencies are obtained for rectangular plates with two cutouts on opposite sides, considering different types of boundary conditions. The study also discusses the small-scale effects for various sizes of cutouts.

Summary: This study investigates the possible coupled elastic waves in a thermoelastic semiconduction micro-beam, considering the coupling effects of the carrier field, temperature field, and elastic displacement field. By incorporating nonlocal strain gradient elasticity, non-Fourier heat conduction, and fraction derivative into the model, a more flexible and enriched model with multiple physical fields coupled is obtained. The study reveals the existence of five possible coupled elastic waves, with comparisons made on the dispersion and attenuation characteristics and their coupling modes. Analysis on the influences of nonlocal parameter, strain gradient parameter, thermal relaxation time, and fraction order parameters are discussed based on numerical results.

Summary: In this paper, a theoretical investigation on the radial vibration of an isotropic elastic nanosphere is conducted. The frequency equation is obtained based on a nonlocal elastic constitutive law, and the validity and accuracy of the theoretical approach are verified through comparisons with literature and numerical examples. The results show that the vibration behavior of the nanosphere is greatly influenced by its size and nonlocal and strain gradient parameters, particularly when the nanosphere radius is smaller than a critical radius. The obtained frequency equation is therefore useful for interpreting experimental measurements of vibrational characteristics of nanospheres.

Summary: The propagation of plane thermoelastic waves in a homogeneous isotropic nonlocal thermoelastic solid is investigated using the Lord-Shulman model of generalized thermoelasticity and the Eringen's model of nonlocal elasticity. It is found that the waves are dispersive and attenuating in nature due to the presence of nonlocality in the medium. Both longitudinal waves and shear-type wave are influenced by the nonlocality, but the shear-type wave is independent of the thermal effect.

Summary: Eringen's fully nonlocal elasticity model leads to ill-posed boundary-value problems and boundary effects, but an enhanced model with a regularizing non-homogeneous local phase provides well-posed boundary-value problems without paradoxes. The enhanced model applied to beam bending is equivalent to a sixth order differential equation with variable coefficients and predicts softening size effects consistently. The influence of the length scale parameter on the beam's response is highlighted, showing a wave pattern in the response function delta(lambda) as the parameter increases.

Summary: This paper investigates size-dependent vibration of single-crystalline nanoplates with cubic anisotropy using the generalized differential quadrature method. The results show that size scale parameters have different effects on vibration depending on material orientation and boundary conditions. In particular, the natural frequency of FCC materials decreases as the nanoplate rotates from [100] to [110] axis.

Summary: This study demonstrates how both cross-sectional nonlocal interactions and axial nonlocality affect the tensile behaviors of nanobars. When the length-to-height ratio is small, nonlocal interactions become significant, while in slender bars, the main nonlocal effect stems from the nonlocal cross-sectional effect. Overcoming the ill-posed problem of pure nonlocal integral elasticity can be achieved by employing both pure nonlocal integral elasticity and surface elasticity.

Summary: In this study, we theoretically investigate the pump-probe response and the four-wave mixing spectrum in a hybrid system composed of a semiconductor quantum dot and a spherical metal nanoparticle. Using a density matrix methodology, we calculate the absorption/gain, dispersion, and four-wave mixing spectra, and analyze their spectral characteristics. We also apply the metastate theory and the dressed-state picture to predict the positions of the spectral resonances.

By analyzing quantum entanglement measures such as entanglement negativity and entropy, the effect of non-Hermitian imaginary hopping on the system is explored. It is found that in the large... limit, the non-Hermiticity reverses the behavior of the ground state energy and low-lying excitations.

Summary: This paper investigates the adsorption and sensing properties of transition metal-doped WSSe gas-sensitive devices towards H2, CO, and CO2 gases related to thermal runaway in Li-ion batteries using density functional theory. The results show that Ti, Mn, and Mo dopants preferentially bind to the S-surface of the WSSe monolayer, and all three monolayers exhibit significantly improved sensing characteristics, with chemisorption towards CO. Band structure analysis suggests that the Ti-WSSe monolayer has the potential to be used as a resistive CO detection sensor. Recovery time calculations indicate the reuse capabilities of the gas-sensitive devices. Mn-WSSe monolayer shows potential for H2 detection, while Mo-WSSe monolayer is more suitable for CO2 detection. This work lays the foundation for potential gas-sensitive applications of WSSe monolayer in thermal runaway scenarios, advancing research in gas sensing domains.

Summary: This paper investigates the effects of electric and magnetic fields on the Goos-Hanchen (GH) shift in a semi-Dirac system. The results show that the magnitude and direction of the GH shift depend on various factors such as incidence angle, electric barrier height and width, and magnetic field. It is observed that there is a saltus step in GH shifts at the critical magnetic field, which decreases with increased potential barrier thickness. Additionally, the GH shift can be significantly enhanced by applying an electric field in the III region. These findings are important for the development of semi-Dirac based electronic devices.

The effects of intralead Coulomb interaction, interdot tunneling, and electron-phonon interactions on differential conductance are investigated. The results show the appearance of destructive interference, Fano interference, and negative differential conductance in strong dot-lead tunneling regions, while a characteristic pattern of positive and negative differential conductances appears in the weak dot-lead tunneling regime.

Summary: Using full electron-phonon interactions and the Boltzmann transport equation, this study investigates the phonon scattering channel and electrical properties of graphene under anharmonic phonon renormalization (APRN). The results show that the APRN reduces the phonon frequency and three-phonon phase space with increasing temperature, affecting the acoustic branch more than the optical branch. The thermal conductivity of graphene decreases after considering three- and four-phonon scattering, and the primary scattering channels are identified. Furthermore, the APRN increases the strength of electron-phonon coupling and leads to an increase in n-type electric resistance at room temperature.
