Summary: The thickness of metallic glass thin films influences their fracture strength and failure mechanisms, with un-notched films transitioning from shear banding to homogeneous deformation as thickness decreases. In contrast, notched films consistently exhibit shear banding regardless of thickness, with a strengthening effect observed near the shear band thickness.

Summary: This work focused on the indentation analysis of nanocolumnar thin films and revealed the importance of microstructure in determining mechanical properties. The study found that a unique analytical thin-film nanoindentation model did not exist and developed a numerical finite element model to understand the contributions of different physical phenomena. By incorporating two length scales and considering densification and buckling of nanocolumnar units, a parametrical representation was developed to accurately predict the elastic modulus variation with depth during indentation tests, leading to a better agreement with experimentally determined values.

Summary: Understanding the mechanical properties of metallic nanoparticles is crucial for their applications. Atomic-scale and continuous calculations are used to analyze gold nanoparticles and reveal that the elastic properties are influenced by their shape rather than size. A descriptor is introduced to distinguish different nanoparticle shapes. The same dependence on shape is observed for copper and platinum nanoparticles, highlighting the universality of the findings.

Summary: This study examines the sensitivity of fragmentation of two spherical solid bodies in a three-dimensional environment to strain rate, using dimensional analysis and numerical simulations. The complete self-similarity of the problem with respect to the effective strain rate parameter is verified through simulations. The critical velocities of fragmentation at high-velocity loading exceed those at low-velocity loading in finite systems but become the same in infinitely large systems, with the critical velocities depending quadratically on system size.

Summary: A novel class of nanostructured Zr50Cu50 metallic glass films with superior and tunable mechanical properties has been produced by pulsed laser deposition. These films exhibit a unique nano-architecture characterized by dense self-assembled nano-laminated atomic arrangement alternating Cu-rich and Zr/O-rich nanolayers with different local chemical enrichment and amorphous or amorphous-crystalline composite nanostructure. These films show outstanding mechanical properties, including large hardness and elastic modulus, and excellent strength/ductility balance, which can be tuned by modifying the film architecture.

Summary: Investigation of titanium thin films deposited on different substrates using e-beam evaporation revealed that thin films on SiNx and NaCl substrates were nanocrystalline, while films on sapphire substrate transformed from nanocrystalline to single crystalline at higher deposition temperatures. Orientations of (0002) were predominantly observed in the single crystalline films grown on sapphire substrate, minimizing surface energy. Results were supported by resistivity measurements showing an increase in resistivity for single crystalline and nanocrystalline films.

However, the relationship between atomic structure and mechanical properties has not yet been fully understood. This study investigates the mechanical properties and thermal stability of amorphous Zr100-xCux TFMGs with different nanostructures, and finds that composition and nanostructure play a significant role in determining hardness, plastic behavior, and fracture resistance.

Summary: The photo-induced enhanced Raman spectroscopy (PIERS) effect occurs when plasmonic nanoparticles on a semiconductor are illuminated by UV light before Raman measurement. The PIERS effect typically lasts for about an hour, with the proposed mechanism being the creation of oxygen vacancies in the semiconductor to facilitate charge transfer. However, this hypothesis has not been experimentally confirmed. In this study, gold nanoparticles co-deposited with porous TiO2 as a PIERS substrate exhibit the highest measured intensity and significantly longer duration (at least 8 days). Cathodoluminescence measurements reveal two distinct mechanisms for co-deposited and drop-casted gold nanoparticles, with the oxygen vacancies hypothesis leaning towards confirmation for the latter, while the narrowing of the depletion zone explains the prolonged PIERS effect.

Summary: Metallic glass films are potential coatings in the nuclear field, but their response to irradiation needs further research. Zr70Ni30 metallic glass films were irradiated by 0.71MeV/u(129)Xe(23+) ions, and changes in structure, morphology, and mechanical properties were studied. The irradiation increased surface smoothening and corrosion resistance. AFM data showed that the surface morphology evolution was due to a transition between viscous flow and evaporation-condensation mechanism. The amorphous structure remained unaffected after irradiation. Nanoindentation revealed softening initially, followed by a slight increase in hardness and Young's modulus. At a critical dose of 0.008 dpa, the hardness increased. The inelastic thermal spike model predicted a track with a radius of 7 nm.

Summary: This paper investigates the evolution of optical and electronic properties of Ta-doped TiO2 films with varying thickness and doping concentration, showing a high degree of tunability. The electrical properties of Ta:TiO2 films deteriorate partially when the thickness is below 20 nm, but conductive ultra-thin films can still be obtained. The optical response changes with Ta addition, leading to a blue-shift in the UV absorption band and an increase in absorption in the IR range due to free carriers.

Summary: This work investigates the formation of adjoining twin pairs (ATPs) at grain boundaries (GBs) in hexagonal close-packed (hcp) metals, focusing on the co-nucleation (CN) of pairs of deformation twins. A continuum defect mechanics model is proposed to study the energetic feasibility of CN of ATPs resulting from GB dislocation dissociation. The model reveals that CN is preferred over the nucleation of a single twin variant for low misorientation angle GBs. Further analysis considering GB character and twin system alignment suggests that CN events could be responsible for ATP formation even at low m' values.

Summary: This study investigates the behavior of electric-field induced antiferroelectric to ferroelectric (AFE-FE) phase transition and reveals the evolution of atomic displacement ordering as the cause for the transition behavior changing from sharp to diffuse. The novel semi-ordered configuration results from the competing interaction between long-range displacement modulation and compositional inhomogeneity, which leads to a diffuse AFE-FE transition while maintaining the switching field.

Summary: In this work, a physics-constrained neural network is used to predict grain-level responses in FCC material by incorporating crystal plasticity theory. The key feature, shear strain rate of slip system, is identified based on crystal plasticity and incorporated into the loss function as physical constitutive equations. The introduction of physics constraints accelerates the convergence of the neural network model and improves prediction accuracy, especially for small-scale datasets. Transfer learning is performed to capture complex in-plane deformation of crystals with any initial orientations, including cyclic loading and arbitrary non-monotonic loading.

Summary: This study attempts to address the gap in cooling rates between thin film deposition and bulk metallic glass (BMG) casting by correlating the glass-forming range (GFR) determined from combinatorial materials chips (CMCs) with the glass-forming ability (GFA) of BMG. The results show that the full-width at half maximum (FWHM) of the first sharp diffraction peak (FSDP) is a good indicator of BMG GFA, and strong positive correlations between FWHM and the critical casting diameter (Dmax) are observed in various BMG systems. Furthermore, the Pearson correlation coefficients suggest possible similarities in the GFA natures of certain BMG pairs.
