Aiming at the existing silicon carbide (SiC) wafer dicing methods with heat affected zone, microcracks, and other damages, laser of SiC using induced thermal-crack propagation (LITP) has been proposed in this paper to achieve low-damage wafer. Based on classical fracture theory, ABAQUS commercial software is used establish a static seam-type crack (SEAM) for simulation analysis. The tip stress distribution extension patterns [[EQUATION]] wafers along different angles are obtained. In...
Orbitally shaken cylindrical bioreactors [OrbShake (OSRs)] without an impeller or sparger are increasingly being used for the suspension cultivation of mammalian cells. Among small volume OSRs, 50‐mL tubes with a ventilated cap (OSR50), originally derived from standard laboratory centrifuge conical bottom, have found many applications including high‐throughput screening optimization cell conditions. To better understand fluid dynamics and gas transfer rates at liquid surface in OSR50, we...
Electrode wear during electrical discharge machining (EDM) is inevitable, and tool electrodes of different materials exhibit rates. Unlike a single-material electrode, for laminated electrode consisting various material foils (LE-VMF), the components suffer from significantly amounts also influence each other in EDM, however, form cause are not clear. Thus, LE-VMFs including symmetric asymmetric were prepared used EDM this paper. The their mutual process investigated through experiments....
Stereolithography-based additive manufacturing of ceramics has received tremendous attention in academic and industrial communities. In order to fabricate silicon carbide (SiC) components with complex shapes by stereolithography, a high SiC loaded ceramic slurry low viscosity excellent curing ability is required. However, it challenging meet these requirements. this work, the effects resin formulation, dispersant, particle size, solid content ball milling time on properties were...
This study investigated the efficacy of a novel correlation power input, energy dissipation rate and mixing time as potential route to identify orbitally shaken bioreactor (OSB) system. The Buckingham’s π-theorem was used designate transform dimensionless Newton numbers with five relevant input variables. These variables were empirically varied evaluate among numbers. number decreases increased shaking frequency filling volume. Previous work has focused on optimizing process by evaluating...
An ultrasonic plasticizing and pressing method (UPP) that fully utilizes vibration is proposed for fabricating thermoplastic polymer surface microstructures with high aspect ratios (ARs). The characteristics of UPP are elucidated based on the plasticization raw material, melt flow, stress template microstructure during forming process. Initially, micronscale single-stage micropillar arrays (the highest AR 4.1) were fabricated by using 304 stainless steel thin sheets pore (through-hole) as...
CFRP exhibits a low specific gravity, good rigidity, and high strength is widely used in the automobile, aerospace, biomedical fields. Against this background, demand for composite components prepared using polymers has increased. The service life of closely related to bonding between polymer. Here, polymethyl methacrylate (PMMA) as raw materials, were via injection molding. First, micro-grooves produced on surface hot-pressing technique. Subsequently, melted PMMA was filled these molding,...
