Summary: The study found that alpha-Sb2O3 nanoflakes exhibit unique bending properties, with a low Young's modulus and remarkable maximum tensile strain, which are attributed to the high-symmetry vdW bonding structure. The vdW nanomechanics have fundamental and technological relevance to nanoelectronics.

Summary: This work presents the mech2d package, a highly automated toolkit for calculating and analyzing the mechanical properties of 2D materials by considering their symmetry. It can fit the second-order elastic constants (SOECs) using both strain-energy and stress-strain approaches. The mech2d package can automatically submit and collect tasks from local or remote machines, making it suitable for high-throughput calculation.

Summary: We report a tunable 2D living self-assembly method for controlling the geometric shape variety and mechanical properties of uniform 2D platelets. The approach involves using n-alkyl alcohols to form a 2D network via hydrogen bonding, resulting in three effects: maintaining the same optical properties and thermal stability, generating alcohol-dependent 2D shape variety, and varying the mechanical properties through the interactions of different alcohol tail lengths.

Summary: This protocol outlines how to utilize atomic force microscopy for measuring the elastic modulus of soft 2D surfaces and cell-laden 3D hydrogels. It includes instructions for sample preparation, instrument calibration, data collection and analysis, and inferring differential matrix remodeling activity in hydrogels. The protocol is suitable for probing a variety of synthetic and naturally derived polymeric hydrogels and allows users to characterize the mechanical properties of multiple surfaces or hydrogels in a single day with introductory AFM training.

Summary: In this paper, in-situ nanoindentation is used to investigate the anisotropic mechanical properties of metallic lithium, which is the desired anode material for high energy density solid state batteries. It is found that the elastic modulus and creep properties of lithium show a significant range depending on sample preparation and testing method. The study also reveals the impact of strain-rate and temperature on battery cycle performance. The global equation for yield strength with strain-rate is established to explain the variations in property values reported in the literature. These findings provide important insights for optimizing the design of solid state batteries and reducing the required pressure.

Summary: Using tape casting-laminating-sintering technique, a three-dimensional porous-dense-porous trilayered Li-garnet framework was developed, allowing symmetric cycling of lithium metal under high current densities for extended periods of time (>500 hours at 3-10 mA/cm(2)). Both experiments (nanoindentation and bending) and simulations (finite element analysis [FEA]) were conducted to investigate the mechanical properties of the 3D framework to understand its ability to withstand high current densities and long-term cycling. The results showed that the dense layer effectively prevents lithium penetration and dendrite growth, the porous layer has high nanomechanical properties to withstand lithium penetration stress, and spherical pores in the porous layer can endure higher lithium penetration forces/stress compared to rectangular/regular pores based on FEA. The flexural strength of the entire structure was also characterized, demonstrating the high strength (30.8-42.1 MPa) of the 3D framework. A rule-of-mixtures model was developed to estimate the flexural strength of the trilayered framework based on its microstructures, and the correlation between mechanical properties and high-rate cycling was discussed.

Summary: This work studied the microstructural evolution and mechanical properties of Ni/Al nanolaminates with varying Ni mole ratio. It was found that the strength of the nanolaminates was enhanced after heat-treatment. A novel NiAl3/Ni2Al3 nanolaminate structure formed when the Ni mole ratio was 0.40, resulting in maximized strength. A homogeneous nanocrystalline NiAl phase formed when the Ni mole ratio was 0.53, leading to excellent ductility and intermediate strength.

Summary: The role of sintering on the microstructure and mechanical properties of ZnGa2O4 pellets was investigated in this study. It was found that the hardness and elastic modulus of the sintered pellets decrease with increased sintering duration. In addition, ZnGa2O4 ceramics show the reverse indentation size effect and have a high storage modulus and low damping factor.

Summary: A material discovery framework is developed to identify new 2D materials using a deep learning-based generative model. The framework utilizes a machine learning model trained on a previous 2D database to predict the mechanical properties of 2D candidates. The validity of the generated materials is verified using a classification model and their similarities to existing 2D materials. The framework successfully identifies 360 new structures and significantly reduces the mean absolute error in predicting mechanical properties.
