Fiber-based coalescers are widely used to accumulate droplets from aerosols and emulsions, where the accumulated droplets are typically removed by gravity or shear. This Letter reports self-propelled removal of drops from a hydrophobic fiber, where the surface energy released upon drop coalescence overcomes the drop-fiber adhesion, producing spontaneous departure that would not occur on a flat ...

Connecting method of optical fibers by V-shaped groove is used in various fields. And in this met,hod, i t is important to estimate distortion of a fiber, because a distortion of the optical fiber influences a connection characteristics. We developed measurement technique of a n optical fiber distortion using Light Intersection Method and optimized incidence angle of the laser beam on a Sample ...

We propose and theoretically study a new hollow-core fiber-based curvature sensing approach with the capability of detecting both radius angle. The method relies on tubular-lattice fiber that encompasses, in its microstructure, tubes three different thicknesses. By adequately choosing placement within cross-section, by exploring spectral shifts transmitted spectrum due to curvature-induced mode...

We develop a numerical approach based on our recent analytical model of fiber structure in the left ventricle of the human heart. A special curvilinear coordinate system is proposed to analytically include realistic ventricular shape and myofiber directions. With this anatomical model, electrophysiological simulations can be performed on a rectangular coordinate grid. We apply our method to stu...

In this investigation an elastic stress analysis is carried out a woven steel fiber reinforced thermoplastic cantilever beam loaded uniformly at the upper surface. The composite beam material consists of low density polyethylene as a thermoplastic (LDFE, f.2.12) and woven steel fibers. Granules of the polyethylene are put into the moulds and they are heated up to 160°C by using electrical resis...

in this study, the influence of the salts as an additive on the performance of the membrane was investigated and an extensive work was performed to optimize pvdf hollow fiber membranes through a response surface methodology (rsm). the prepared membranes were characterized by sem, contact angle and lep measurement. then, the rsm was used for the optimization of surface pore size, porosity and hy...

Hydrophilic polyethersulfone (PES) hollow fiber membranes were prepared via non-solvent induced phase separation (NIPS) by addition of polymeric additives as a membrane modifying agent. The effect of the addition of hydrophilic surfactant Pluronic F127, Polyivinylpyrrolidone (PVP), and Tetronic 1307 on the performance of the final PES hollow-fiber membrane was investigated. The morphology of fa...

The purpose of this article is to investigate the influences of carbon fibers on the fracture mechanism of carbon fibers both in macroscopic view and microscopic view by using single-point flying cutting method. Cutting tools with three different materials were used in this research, namely, PCD (polycrystalline diamond) tool, CVD (chemical vapor deposition) diamond thin film coated carbide too...
