Laser powder bed fusion (LPBF) is one of the most commonly used metal additive manufacturing technologies due to its advantages in fabricating complex structures. The LPBF process utilizes laser scanning melt and consolidate powders, which tool paths are often referred as scan pattern. However, traditional patterns could cause large distortion residual stresses induced during fabrication process. Although recently some studies have attempted develop optimization methods instead using...
The aim of this study was to design a hemi-pelvic prosthesis for patient affected by pelvic sarcoma. To investigate the biomechanical functionality pelvis reconstructed with designed custom-made prosthesis, patient-specific finite element model whole primary ligaments inclusive constructed based on computed tomography images patient. Then, analysis performed calculate and compare stress distribution between normal implanted models when undergoing three different static conditions-both-leg...
We study theoretically magnetohydrodynamic (MHD) motion of a binary electrolyte in concentric annulus subjected to uniform, axial magnetic field. The annulus’ cylindrical surfaces serve as electrodes. When potential difference is imposed across the electrodes, radial electric current flows solution and interacts with field induce Lorentz body force that drives azimuthal fluid flow. infinitely long, purely flow (analogous classical Dean flow) possible. determine velocity profile, ion...
The development of coiled tubing operation technology has continuously improved with the higher requirements on-line detection technology. current field weak magnetic system calculates gradient signal for improving locating precision. Quantitative identification defect shape, based on and leakage flux systems, is a key issue to evaluate whether can continue be used. 2-D finite-element models different typical shapes were established, changes magnetic-field intensity are calculated. influence...
Coiled tubing technology is widely used in drilling and repairing operations, the quality of bias weld directly determines fatigue life coiled tubing. The microstructures consistency between base metal that whether resistance reaches level metal. In this paper, multi-frequency eddy current testing technique to detect reactance zone material within steel strip, which can be determine microstructure area area, turn improve welding heat treatment process. work, CT100 CT90 materials with for...
Direct metal deposition (DMD) process has been regarded as a promising additive manufacturing technology. But this is hard to fabricate structures with overhang features in support-free manner because the machine equipped 3-axis platform could only 2.5 dimensions instead of 3 dimensions. Therefore, multi-axis DMD developed complicated without support combined motion platform. Decomposition operation input 3D model generate several sub-volumes and following regrouping are two key procedures...
The biosensor based on surface acoustic wave is of great significance for the application biological clinical detection, but sensitivity and specificity still need to be improved. In this article, structure interdigital transducer designed by studying theoretical model biosensor. Then amplitude–frequency response device studied. Later, simulation established, performance numerically calculated. Meanwhile, relationship between applied excitation signal resonant frequency considered,...
We evaluated the immunogenicity and protective ability of a chimpanzee replication-deficient adenovirus vectored COVID-19 vaccine (BV-AdCoV-1) expressing stabilized pre-fusion SARS-CoV-2 spike glycoprotein in golden Syrian hamsters. Intranasal administration BV-AdCoV-1 elicited strong humoral cellular immunity animals. Furthermore, vaccination prevented weight loss, reduced infectious virus titers lungs as well lung pathology provided protection against live challenge. In addition, there was...
摘要: 为了提高聚醚醚酮(Poly-ether-ether-ketone,PEEK)熔融沉积成形(Fused deposition modeling,FDM)强度,利用正交试验方法研究了FDM打印工艺参数与力学性能之间关系。对喷嘴温度、打印速度和填充角度等影响因素下PEEK样件的力学性能进行对比分析,研究现有条件下最优打印参数,提高成形质量。结果表明各个工艺参数对试验结果的影响程度不相同,影响最为明显的是喷嘴温度,其次是填充方式,打印速度对试验结果的影响较小。最佳工艺参数组合为:喷嘴温度420℃,打印速度10mm·s-1,填充方式0°。改善工艺参数后可提高PEEK成形件的强度,制造出的个性化假体的力学性能能够满足临床使用的要求。一例PEEK假体已经成功应用于临床,为其在临床上的广泛应用奠定基础。
Inflammatory reaction and neovascularization are crucial physiological processes that occur during postoperative wound healing. However, excessive inflammatory response uncontrolled angiogenesis lead to scar formation, which severely limits the success rate of glaucoma filtration surgery. Peptide hydrogels were well-established possess good biocompatibility, inherent biodegradability, extracellular matrix analog property, high drug loading efficiency. Herein, we examined potential...
The continuous directed energy deposition (DED) method has been utilized to process various kinds of slender structures with different materials due its uninterrupted characteristics. characteristics the specimen fabricated by this DED may not be same as that in conventional temperature histories. In study, NiTi shape memory alloy on phase constituent and microstructure are investigated. Results indicate higher laser power shows more Ti2Ni precipitation, increased defects (e.g., voids,...
Abstract Nickel-Titanium (NiTi) shape memory alloys (SMAs) are a class of promising materials for bio-implant, transportation, and aerospace applications. These interesting applications SMA as result their ability to exhibit effect (SME) super-elasticity (SE). SMAs, especially NiTi which has been proven have good mechanical properties, however limited by operational fatigue reported in the literature. In this paper, near equiatomic was hybridized with zirconium (Zr), molybdenum (Mo) copper...
