Positive temperature coefficient of resistivity (PTCR) hollow fibers that exhibit self-regulating heating characteristics have potential applications in temperature-swing adsorption systems (TSA), such as CO2 recovery and drying compressed air. La-doped BaTiO3 displaying a PTCR effect were produced by phase inverting casting solution consisting N-methly-2-Pyrrolidone, polymethyl methacrylate, p...

Metal–ceramic composite beads containing different amounts of tantalum and alumina, particularly 100 vol% 60–40 tantalum/alumina, are produced by the alginate gelation process. Sodium is used as gelling agent in metal–ceramic suspension, while a calcium chloride solution prepared to trigger consolidation As previous study, nozzles order obtain three sizes. The largest result be hollow, hence re...

This study addresses a ubiquitous challenge in powder metallurgy: sintering distortion. Sintering distortion can have various causes. On one hand, external factors such as friction with the support during or temperature gradients furnace, and, on other internal anisotropic shrinkage due to directional layer build-up residual stresses production, cause deformation by relieving mechanical stress....

This study used a three-dimensional (3D) printing process to develop the Ag/AgCl/TiO2 coupled photocatalyst with specific surface area of 748 mm2/g. We examined catalytic capability this in degrading methyl blue (MB) dye and sterilizing Escherichia coli as well durability reliability its continuous use. A TiO2 module was constructed through fused filament fabrication (FFF), adopted 3D composed ...

It is predicted theoretically that a 1D diatomic chain of 3D chiral cells can support topological bandgap allows for translating small time-harmonic axial movement at one end the into resonantly enhanced large rotation an edge state other end. This topologically protected such arbitrary mass mirror does not shift eigenfrequency out bandgap. Herein, this complex laser-beam-scanner microstructure...

Mica is a group of clay minerals that are frequently used to fabricate electrical and thermal insulators as adsorbents for the treatment cationic pollutants. However, conventional subtractive manufacturing has drawback poor three-dimensional (3D) shape control, which limits its application. In this study, we propose digital light processing (DLP)-based additive (AM) one most effective ways addr...

Owing to its remarkable properties, multiwalled carbon nanotubes (MWCNTs) are attracting the interest for realization of sensors. The potential MWCNTs high temperature sensing applications was investigated by integration within reinforced aluminium oxide ceramic composite. up 2 wt% were mixed with aluminum composite using solution mixing method ensure good homogeneilty powders. Specimens realiz...
