Carbon Nanotube Fibers Decorated with MnO2 for Wire-Shaped Supercapacitor
Fibers made from CNTs (CNT fibers) have the potential to form high-strength, lightweight materials with superior electrical conductivity. CNT fibers have attracted great attention in relation to various applications, in particular as conductive electrodes in energy applications, such as capacitors, lithium-ion batteries, and solar cells. Among thes...
Lattice implants that generate homeostatic and remodeling strains in bone
Bone remodeling is mediated by several factors including strain. An increase in strain between 1% and 10% compared to homeostasis can trigger bone formation. We aim to create an orthopedic implant using clinically established imaging and manufacturing methods that induces this strain control in human bone. Titanium scaffolds were manufactured with ...
Application of 3D bioprinting in the prevention and the therapy for human diseases
Rapid development of vaccines and therapeutics is necessary to tackle the emergence of new pathogens and infectious diseases. To speed up the drug discovery process, the conventional development pipeline can be retooled by introducing advanced in vitro models as alternatives to conventional infectious disease models and by employing advanced techno...
Suppression of adiabatic shear band formation by martensitic transformation of retained austenite during split Hopkinson...
In this study, a high-strength bainitic steel was fabricated and austempered at 350 ?C for 15 min, 90 min, and 24 h to control the volume fraction of retained austenite (RA) while keeping an appropriate hardness level. Their dynamic compressive properties were investigated in relation to the ASB formation and cracking by the SHPB. The specimen aust...
Alloy design against the solidification cracking in fusion additive manufacturing: An application to FeCrAl alloy
This study developed a design methodology against liquid-state cracking by combining the Scheil–Gulliver solidification simulations and Machine Learning analysis to design alloys for Fusion Additive Manufacturing. Applying this design approach resulted in a Fe–20Cr–7Al–4Mo–3Ni. The alloy was successfully printed with relative densities of over 99%....
Chiral lattices filled composite tubes under uniaxial and lateral quasi-static load: experimental studies
The research investigates the energy absorption characteristics of chiral auxetic lattices filled cylindrical composite tubes subjected to a uniaxial and lateral quasi-static load. The lattice structures were manufactured using a 3D printing technique. Carbon fiber composite tubes without filler material were initially subjected to uniaxial and lat...
Parametric optimization for improving the machining process of Cu/Mo-SiCP composites produced by powder metallurgy
The features of composite materials such as production flexibility, lightness, and excellent strength put them in the class of materials that attract attention in various critical areas, i.e., aerospace, defense, automotive, and shipbuilding. However, the machining of composite materials displays challenges due to the difficulty in obtaining struct...
Enhanced negative thermal expansion of boron-doped Fe43Mn28Ga28.97B0.03 alloy
...
Enhanced negative thermal expansion (NTE) properties are achieved by introducing a little amount of boron in the Fe43Mn28Ga28.97B0.03 alloy. As a result, this alloy shows a giant NTE coefficient of alpha(1) = -79.7 x 10(-6) K-1 in a wide temperature range from 277 K to 136 K. Compared to the NTE characteristics in Fe43Mn28Ga29, the NTE operation te...
