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: A nonlocal strain gradient model is developed for the buckling analysis of functionally graded Euler-Bernoulli beam subjected to thermo-mechanical loads. The governing equations incorporate the effects of nonlocal and strain gradient parameters. Thermal properties over the cross section are graded using the power law. The proposed model compares well with the existing literature in the limiting sense of no nonlocal and gradient effects.

Summary: This paper proposes two new nonlinear nonlocal Euler-Bernoulli theories to model the mechanical properties of nanobeams and investigates the static bending and forced vibrations of single-walled carbon nanotubes. The results show that both material nonlinearity and nonlocal effects have significant impacts on the mechanical properties of single-walled carbon nanotubes.

Summary: Although the individual effects of small-scale effect and thermal stress on nanobeams have been studied, their combined effects and the temperature dependence of elastic parameters have not been thoroughly investigated. In this paper, a new nonlocal nonlinear Euler-Bernoulli theory is proposed to model the mechanical properties of nanobeams, considering both small-scale effect and thermal stress, as well as the temperature dependence of Young's modulus. The study demonstrates that thermal stress and temperature dependence have a significant influence on the mechanical properties of slender nanobeams, compared to the small-scale effect induced by the nonlocal effect. Neglecting the temperature effect may lead to qualitative errors in the analysis of slender nanobeams.

Summary: The viscoelastic buckling and nonlinear post-buckling behavior of nano-scaled beams were analyzed using the nonlocal integral elasticity theory. The study developed a finite element method and considered buckling related terms and viscoelastic effects. The results were compared with literature and the effects of nonlocal parameter, viscoelastic parameter, axial compressive load, and boundary conditions on the buckling and post-buckling behavior were investigated.

Summary: This paper presents a nonlinear formulation for beam-type structures using stress-driven nonlocal theory within different boundary conditions. The study investigates the bending response of beams under various conditions and compares the linear and nonlinear results using a numerical method. The influences of factors such as volume fraction/distribution pattern of graphene platelets, nonlocality, elastic foundation, and geometrical parameters are examined.

Summary: This paper investigates the free vibrational behavior of two crossed graphene nanoribbons (GNRs) in an elastic medium using nonlocal continuum-based models and van der Waals (vdW) forces. Numerical studies show that considering non-uniform vdW forces and the intersection angle significantly affect the vibration of the system.

Summary: This study presents an efficient solution method based on the Stokes' transformation to investigate the effects of deformable boundary conditions and axial point load on the transverse vibration of a nanobeam. The eigenvalue problem obtained by using Fourier sine series and Stokes' transform can be used to analyze the frequencies of nanobeam applications subjected to vibration and axial force at both rigid and non-rigid boundaries. This analytical method can be applicable to various nanotechnology structures and machines.

Summary: In this paper, a novel nonlocal anisotropic elastic shell model is developed to investigate the nonlinear vibrations of double-walled carbon nanotubes. The linear and nonlinear vibration analyses are performed to obtain the approximate natural frequencies and modal shapes, as well as the hardening nonlinear behavior. Molecular dynamics simulations are used to calibrate the model parameters.

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: The global SARS-CoV-2 pandemic has driven a surge in demand for rapid and efficient viral infection diagnostic tests, leading to a shortage in diagnostic test consumables. A new method using carbon nanotubes and ssDNA sequences has been developed to achieve high-yield extraction of viral nucleic acids, with a 100% extraction yield of target SARS-CoV-2 RNA. This method allows direct extraction of nucleic acids from human saliva, bypassing the need for further biofluid purification and commercial extraction kits.
