In the field of bionic soft robots and microrobots, artificial muscle materials have exhibited unique potential for cutting-edge applications. However, current mainstream thermal-responsive muscles based on semicrystalline polymers (SCPs), despite their excellent physical properties, suffer from limitation environmental stimuli in practice, while photodriven counterparts adopting liquid crystal elastomers (LCEs) lack ductility. Herein, a novel multifunctional programmable with patch-sewing...
Holmium:yttrium–aluminum-garnet (Ho:YAG) laser lithotripsy (LL) has been the treatment of choice for kidney stone disease over two decades, yet mechanisms action are not completely clear. Besides photothermal ablation, recent evidence suggested that cavitation bubble collapse is pivotal in dusting when Ho:YAG operates at low pulse energy (Ep) and high frequency (F). In this work, we perform a comprehensive series experiments model-based simulations to dissect complex physical processes LL....
Over the past seven years, full-field analyses of a wide range classical as well modern quasi-static fracture experiments on nominally elastic brittle materials -- ranging from hard ceramics to soft elastomers have repeatedly identified material strength surface one key properties that governs not only nucleation cracks, but also their propagation. Central these are results generated by Griffith phase-field theory with introduced in [21,23,20]. The first two objectives this paper is extend...
To enhance the photocatalytic efficiency of TiO2, different concentration Ce3+-doped TiO2 nanotubes were prepared using a sol-gel method combined with hydrothermal process. After being calcined at 450°C, morphology, composition, and crystal structures investigated by SEM, TEM, XRD, EDS. The samples' performance was characterized degrading methylene blue under illumination 250 W UV-light. result showed that both ends ringent consisted many layers. Their length could reach to hundred...
Since its introduction in the 1940s until present times, so-called Brazilian test has been embraced by practitioners worldwide as a method of choice to indirectly measure tensile strength concrete, rocks, and other materials with large compressive relative their strength. This is because ease that affords both preparation specimen (a circular disk) application loads (two platens compressing between them). Yet, this practical advantage be tempered fact observations from --- being an indirect...
We propose a new direction-dependent model for the unilateral constraint involved in phase field approach to fracture and also continuous damage mechanics models. The construction of this is informed by micromechanical modeling through homogenization theory, where representative volume element (RVE) has planar crack center. proposed made closely match response RVE, including frictionless self-contact condition. This allows identify with tension-compression split obtained from cracked...
