Summary: In this study, a strategy utilizing oxygen vacancy concentration modulation was used to successfully grow semiconducting single-walled carbon nanotubes (s-SWCNTs) with narrow diameters. The Fe0.01Mg0.99O/CeO2(3) catalyst was employed to provide oxygen vacancies, allowing for selective etching of chemically active carbon nanotube caps during the growth process. The optimized conditions resulted in high purity s-SWCNTs with uniform diameters.

Summary: This study aims to establish a novel approach to better understand and predict the behavior of materials with multi-scale lamellar microstructures. High-resolution reconstruction and collaborative characterization methods are used to accurately represent the microstructure. The mechanical properties of pearlite are investigated using crystal plasticity simulation and in-situ scanning electron microscopy tensile testing. The results validate the reliability of the novel strategy.

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: Due to their laminated structure, MAX phases and MAX-phase-like compounds possess excellent damage tolerance capability, thermal/electrical conductivity, and other functional properties, showing promising prospects for structural-functional applications. In this study, a new MAX-phase-like ternary carbide, V8P6C, with layered characteristics was discovered. It has a layered structure formed by repeated stacking of V6C-octahedrons and VP6-distorted-octahedrons, exhibiting thermal expansion anisotropy and high compressibility anisotropy. The unique structure and properties of V8P6C were revealed through experiments and calculations, and its good damage tolerance capability was predicted.

Summary: Depositing a Ni-1at. % P film can facilitate the formation of multiple quintuple twin junctions, resulting in a five-fold twin structure and a pentagonal pyramid surface topology. The ability to control material structures offers opportunities for creating novel surface topologies, which can be used as arrays of field emitters or textured surfaces.

Summary: This study proposes a combined large-scale first principles approach with machine learning and materials informatics to quickly explore the chemistry-composition space of advanced high strength steels (AHSS). The distribution of aluminum and manganese atoms in iron is systematically explored using first principles calculations to investigate low stacking fault energy configurations. The use of an automated machine learning tool, DeepHyper, speeds up the computational process. The study provides insights into the distribution of aluminum and manganese atoms in systems containing stacking faults and their effects on the equilibrium distribution.

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: The advent of the intelligent era has brought convenience to our lives but also brought threats from electromagnetic radiation. It is urgent to develop new electromagnetic wave absorption materials with lightweight, strong absorption, tunable absorption frequency, and wideband absorption. In this study, a novel electromagnetic wave absorber was obtained by constructing La0.8CoO3-rGO nanocomposite. The hybridization ratio of La0.8CoO3 and rGO was found to affect the microwave absorption properties. The La0.8CoO3-rGO nanocomposite showed excellent absorption performance and potential for high-efficiency microwave absorbers.
