Abstract Powder based high speed sintering (HSS) improves the printing efficiency compared to SLS printing. The shortened layer time for HSS requires quick melting and solidification of powders, which is a big challenge for traditional printing powders materials, especially the viscous elastomers. Herein, a dynamic cross-linked polyurethane containing Diels-Alder bonds (PUDA) was synthesized at kilo scale and used for HSS. The incorporation of dynamic DA bonds into PU enables the dissociation of the polymer chain under IR light heating, and will lead to fast relaxation, diffusion and dis/re-entanglement, addressing the problem of incomplete sintering and weak… More >

Abstract Zn is a promising biomedical implant for its good biocompatibility, moderate mechanical strength, and suitable degradation rate. As a novel fabricating method, Additive Manufacturing (AM) could prepare biomedical Zn by raw powder deposition, melting, and molten pool solidification in a layer-by-layer pattern, which favors the customized shape and well-controlled geometry of the final product. Meanwhile, the rapid heating and solidification from AM often induces unique structural changes compared with traditional fabrication techniques, thus subsequently affecting the degradation behavior. Still, setting up the correlations among AM fabrication, structural changes and degradation behavior of Zn remains a… More >

Abstract One intriguing phenomenon in seismograms is seismic coda, once dismissed as noise. In 1969, seismologist Aki proposed that these coda waves reveal critical insights into small-scale inhomogeneities in the Earth's interior [1]. This scattering effect highlights geological complexity and offers valuable information for exploring targets like unconventional oil and gas reservoirs [2-5]. This paper examines elastic wave propagation and scattering in solid media. We validate the effectiveness of simulating wave field scattering by employing the discrete element method alongside energy radiative transfer theory. Then, we explore elastic wave scattering and scale inversion of non-homogeneous bodies More >

Abstract The capacity to maintain operational temperatures within safe thresholds is paramount for the longevity of thermal barrier coating systems (TBCs). Nonetheless, TBC spallation during service can lead to localized over temperature, which may result in catastrophic failure. In this study, we examine the phenomenon of over temperature in locally spalled TBCs through a combination of numerical simulations and experimental investigations. We perform numerical calculations to determine the temperature distributions in locally spalled TBCs with varying spallation depths and diameters, and we analyze the correlation between the maximum temperature within the spalled regions and the dimensions… More >

Abstract In this paper, a novel porous thermoelastic model is developed, building upon the existing framework of thermoelastic model. The objective of this study is to investigate the thermoelastic response behavior of porous materials. The Klein-Gordon (KG) operator is employed to describe the effect of spatio-temporal non-localization in the constitutive equation, and the memory-dependent derivative (MDD) is incorporated into the Moore-Gibson-Thompson (MGT) heat conduction equation. The model is applied to study the thermoelastic response of hollow porous cylinders under thermal shock, which accurately captures the complex micro-interaction characteristics and memory-dependent properties of the porous structure.

Abstract Please Creating mechanically robust tissue engineering scaffolds capable of delivering growth factors and stem cells in situ for hard tissue repair remains a significant challenge. Inspired by the spiral structure of ice cream, our group developed an advanced 3D printing technique known as cryogenic 3D printing to fabricate polyester-based scaffolds with embedded growth factors. This method utilizes water-in-oil (w/o) polyester emulsions containing growth factors as the printing ink, which is patterned onto a cryogenic substrate. The resulting scaffolds feature a hierarchically porous structure, allowing mesenchymal stem cells (MSCs) to easily attach and proliferate. Additionally, the… More >

Abstract In addressing the challenging problems of underwater communication, mechanical antenna (MA) provides a new direction for greatly reducing the size of low frequency communication equipment and breaking through the Chu-Harrington limit [1,2]. MA refers to the generation of low-frequency electromagnetic waves by mechanically driving materials with strong electric or magnetic fields. This direction has attracted many researchers from fields such as materials, mechanics, and mechanics to conduct research. Various forms of MA currently exist, but research on their modulation methods remains limited. The modulation methods of MA primarily include amplitude modulation, frequency modulation, and phase More >

Abstract Shape memory alloys (SMA), with their unique phase transformation capability, can deform under external force and recover their original shape through a martensite-to-austenite phase transformation triggered by heating [1]. Utilizing this characteristic, SMA wires can be pre-stretched and fixed, generating internal stress during shape recovery, which increases the natural frequency of SMA wire structures [2]. This property is of significant importance in structural dynamics design. Based on this, structures incorporating SMA wires and SMA-reinforced plate structures can be designed to dynamically adjust their natural frequencies and control structural dynamic responses. Furthermore, the vibration modes of More >

Abstract 1 Introduction
Joint and cardiovascular diseases, such as osteoarthritis (OA) and myocardial infarction (MI), pose significant clinical challenges due to their limited regenerative capacity. The key to mitigating tissue damage and preventing the progression of OA and MI is to repair or even regenerate the infarcted tissue. At present, cell-based therapy is the primary strategy for tissue repair. Delivered cells could either differentiate into functional cells or secrete paracrine signals to promote onsite cell function. Both mechanisms have demonstrated potential in cartilage and cardiac tissue repair, both preclinically and clinically. In addition to cell therapy,… More >

Abstract The mechanism of vertical extension in high-volume hydraulic fracturing is of significant importance for the volumetric transformation of low-permeability reservoirs in deep offshore sandstone formations. The complexity of fracture propagation behavior is influenced by the characteristics of discontinuous thin layers in the vertical plane. However, the mechanisms and influencing factors of fracture extension in the vertical direction during high-volume hydraulic fracturing remain unclear. This study integrates true triaxial hydraulic fracturing experiments with acoustic emission (AE) monitoring, employing a nonlinear finite element method to establish a multi-thin interlayer fracturing model based on seepage-stress-damage coupling.

Abstract Traditionally, it is relatively easy to process metal materials and polymers (plastics), while ceramic and inorganic semiconductor materials are hard to process, due to their intrinsic brittleness caused by directional covalent bonds or strong electrostatic interactions among ionic species. This brittleness can degrade semiconductor performance and lead to catastrophic failures, thereby limiting their application scenarios and service lifetime. Achieving room-temperature deformability in semiconductor materials without compromising their functionality has been a long-standing goal in materials science. Recently, room-temperature ductile semiconductors have emerged, with their deformability enhanced by factors such as size effects, fewer pre-existing micro-cracks,… More >
