Abstract null null In this paper, a novel Free-size Optimization based Graded Lattice Generation (FOGLG) method, that generates the functionally graded lattice (FGL) structures using free-size optimization, is proposed. In addition, the reconstruction method suitable for the construction of 3D FGL structures using Additive Manufacturing (AM) is presented. The proposed method employs the thickness information of each shell element obtained from a free-size optimization algorithm to determine the ...

Abstract null null The phase constitution of the joint had a significant effect on the mechanical properties of the welded components. In this study, a thermo-metallurgical finite element model was developed for the hybrid laser arc welding process to predict the phase field and melt-pool dimensions of double-sided butt-welded chromium-molybdenum steel plates. The good agreement of the predicted phase fields and melt-pool dimensions with experimental results showed the potential of the numerical...

Abstract null null Powder bed defects usually inevitably appear in the process of powder spreading during laser powder bed fusion owing to the characteristics of the powder material and the performance of the spreading equipment. This may lead to instability with regard to subsequent processes and the quality of the final part. Defect detection based on the imaging process is an effective way to achieve non-contact, efficient, and accurate online monitoring, and it has received widespread attent...

Abstract null null Probiotics have recently received increasing attention in a range of biomedical applications, such as antimicrobial agents, tissue repair and regeneration, as well as disease treatment. However, the activity and viability of probiotics are significantly affected by complicated tissue/organ environment and thus the probiotics can not stay steady at the target location. Probiotic encapsulation is developed as a biotechnological tool to cope with the technological issues derived ...

Abstract null null At present, the shortage of potable water is still a critical issue. The emerging of solar-driven evaporation technique offers a promising way to solve freshwater scarcity. However, developing highly efficient evaporation system is still a challenge. Herein, this work developed two-dimensional heterostructure nanosheets as the photothermal agent. We used the WSe2 nanosheets to enhance the absorption of graphene and facilitate the heat localization due to its higher visible lig...

Abstract null null This paper presents an experimentally validated framework used to perform topology and orientation (morphology) optimization of lattice structures subject to stress constraints. The effective stiffnesses and yield stresses of a unit cell are obtained using numerical homogenization and validated experimentally. Due to the orthotropic behavior of the unit cell, the modified Hill’s yield criterion is used to describe the lattice strength. The effective orthotropic properties are ...

Abstract null null Traditional photothermal therapy (PTT) usually requires hyperthermia (greater than50 °C) to mediate effective tumor ablation, which could inevitably induce heating damage to the adjacent normal tissues. Therefore, to achieve effective tumor killing at relatively low temperature is crucial to improve the application of PTT. MoS2, as an attractive photothermal agents, have attracted much attention in biomedical applications. But the separation of exfoliation and functionalizatio...

Abstract null null Additive manufacturing of ceramics is transforming electromagnetics by providing density-varying lattices and stochastic foams within arbitrary envelopes. Periodic structures can now be fabricated with zirconia which offers the highest permittivity of any 3D printable material possible to be printed with nearly-full-density. By arranging a lattice with variation in the strut and node sizings as well as unit cell dimensions, the effective density of a structure can be spatially...

Abstract null null An entropy-stabilization strategy was applied to engineer a novel thermal insulating material by establishing a single-phase solid solution with the formula of (Y1/2Yb1/2)2(Ti1/3Zr1/3Hf1/3)2O7 (YYHEO). Structural analysis revealed that this material exceeded the typical substitutional solubility limit, even with a significant atomic size difference, where the conventional determination rule was defied. YYHEO exhibited a lower glass-like thermal conductivity due to its highly d...
