Summary: This research demonstrates the formation of 2D materials on 3D metal halide perovskites using low electron-fluence scanning transmission electron microscopy. It provides insights into the dynamics of the heterointerface and its implications for the stability of 2D-on-3D composites. The findings also have implications for the engineering and enhancement of stability in these systems.

Summary: Meniscus-confined electrodeposition (MCED) has attracted widespread attention due to its simple physical construction and low economic cost. The key to continuous and stable deposition in MCED lies in the matching of probe lifting rate and growth current. A novel electrodeposition physical model based on theta-pipette is proposed, along with a closed-loop control method to ensure stable fabrication of high-aspect ratio microstructures.

Summary: The resolution of conventional acoustic imaging methods in large-aspect-ratio cabins is limited by array parameters and reverberation. The non-synchronous measurements technique breaks through these limitations and can achieve high-resolution acoustic imaging.

Summary: Hydraulic fracturing is widely used in the oil industry to stimulate low permeability reservoirs. Modeling hydraulic fracturing requires considering the deformation of fracture walls, fluid flow inside the fracture, and fracture propagation through the porous medium. This study aims to extend the applicability of high aspect ratio interface elements to simulate three-dimensional induced hydraulic fractures. The proposed methodology involves a deformable porous media with fluid flow governed by Darcy's law and a tension continuum damage model for fracture formation. The results demonstrate that the 3D interface elements adequately replicate the main characteristics of hydraulic fracturing, such as fracture aperture, length, and injection pressure.

Summary: This study investigates a bimaterial strip made of Aluminum-Epoxy pair with a crack terminating at an arbitrary angle to the interface subjected to bending using photoelasticity technique. The shape of the photoelastic fringe patterns observed at the crack tip varies based on the crack inclination angle. The results show that the SIF values increase with the crack inclination angle.

Summary: The stress rupture anisotropy of a Ru-containing fourth generation single crystal superalloy was studied at different temperature and stress conditions. The ruptured microstructure and deformation mechanisms were investigated, and the determinants of anisotropic performance were examined. The results showed that the alloy exhibited strong anisotropy at intermediate temperature and high stress due to the dependence of deformation on Schmid factors. The addition of Ru reduced stacking faults energy and encouraged the formation of stacking faults, thereby reducing stress rupture anisotropy.

Summary: Understanding the relationship between post-caldera reactivation of caldera boundary faults and the cooling process of volcanoes is crucial for reconstructing the geomorphological history of calderas and assessing volcanic and seismic hazards. Research has found that the reactivation of caldera boundary faults during the cooling process is likely induced by regional stresses. Therefore, the reactivation of caldera boundary faults induced by regional stresses should be taken into consideration in reconstructions of the geomorphological evolution of calderas and associated hazard assessments.

Summary: We developed a novel solution for fabricating ultrahigh aspect ratio embedded metal meshes (EMMs) by microscale hybrid printing nano silver paste. With an improved printing nozzle and imprinting process, we achieved an EMM with the highest AR ever reported (20.1). The resulting flexible transparent electrode displayed remarkable photoelectric performance and excellent optoelectronic properties after rigorous mechanical and environmental stability tests.

Summary: Traditional interface models assume the interface is located at the middle of finite-thickness interphases, but this may not be applicable in graded or inhomogeneous interphases. New research extends the interface model to consider arbitrary interface positions and proves that interface position does not necessarily coincide with the mid-layer. The importance of interface position is demonstrated through a series of examples.

Summary: In this study, a rich-interface heterostructured In2O3/InP catalyst was designed for photocatalytic CO2-to-CH3COOH conversion and O2 generation under visible light. XANES analysis revealed the presence of O-In-P polarized sites at the interface, while FT-IR and Raman spectra identified key intermediates for acetate production. DFT calculations demonstrated that the rich O-In-P polarized sites promoted C-C coupling to form C2 products.

Summary: The crossflow response of a flexible riser subjected to vortex-induced vibration has been investigated using numerical simulation. The study found that the response mode depends on the aspect ratio, flexural rigidity, and shear flow profile, while the addition of helical wires can significantly reduce the VIV displacement response.

Summary: This paper addresses the limitations of atomic force microscopy (AFM) measurement by using a large-range AFM system consisting of a novel repairable high aspect ratio probe (HARP) and a nested-proportional-integral-derivative (nested-PID) AFM system. The HARP is fabricated using a reliable and cost-efficient bench-top process and is tested on polymer trenches for superior image fidelity. A nested-PID system is also developed and employed for 3D characterization of 50 μm-step samples.

Summary: This study investigates the driving force of Suzuki segregation in the Co-Ni binary system and predicts temperature- and composition-dependent stacking fault energies. Configurational and vibrational effects aid in stabilizing stacking faults, with segregation of Co to the innermost planes of the faults. The method developed here could be used to inform alloy design strategies and predict segregation in other interfacial problems.

Summary: Perovskite solar cells show great promise as an alternative to traditional photovoltaic technologies, with 2D/3D hybrid cells offering improved stability and efficiency. However, further research is needed on the degradation processes and charge dynamics at interfaces to enhance long-term performance. Analysis of the Au/HTM/perovskite interface degradation suggests it significantly impacts charge accumulation and impedance, leading to efficiency loss.
