A multichannel mixed-conducting hollow fiber (MMCHF) membrane, 0.5 wt % Nb2O5-doped SrCo0.8 Fe0.2O3-d (SCFNb), has been successfully prepared by phase inversion and sintering technique. The crystalline structure, morphology, sintering behavior, breaking load, and oxygen permeability of the MMCHF membrane were studied systematically. The MMCHF membrane with porous-dense asymmetrical microstructu...

Flexible electronic devices offer the capability to integrate and adapt with human body. These devices are mountable on surfaces with various shapes, which allow us to attach them to clothes or directly onto the body. This paper suggests a facile fabrication strategy via electrospinning to develop a stretchable, and sensitive poly (vinylidene fluoride) nanofibrous strain sensor for human motion...

To understand the effect of fundamental thermal noise in hollow-core optical fibers, authors propose an adapted model and compare it to careful measurements. They find that use evacuated hollow cores could allow for order-of-magnitude improvement phase sensitivity with respect standard fiber, enabling better precision interferometric applications such as fiber gyroscopes laser frequency stabili...

There has been very little work done in the past to extend the wavelength range of fiber image bundles to the IR range. This is due, in part, to the lack of IR transmissive fibers with optical and mechanical properties analogous to the oxide glass fibers currently employed in the visible fiber bundles. Our research is aimed at developing high-resolution hollow-core coherent IR fiber bundles for...

The current paper presents the development and characterization of polyvinylidene fluoride (PVDF)-Zn2GeO4 (ZGO) fine fiber mats. ZGO nanorods (NRs) were synthesized using a hydrothermal method incorporated in PVDF solution to produce mats prepared by varying concentration NRs (1.25–10 wt %) Forcespinning® method. developed showed long, continuous, homogeneous fibers, with average diameters from...

Chlorination-induced changes in the physicochemical characteristics of effluent organic matter (EfOM) and their role fouling hollow fiber polyvinylidene fluoride (PVDF) microfiltration membranes during wastewater reclamation was mechanistically investigated. Pre-chlorination strongly influenced pressure rise constant flux forward filtration as well hydraulically irreversible by backwashing with...

In this review paper some recent advances on optical fiber sensors are reported. In particular, fiber Bragg grating (FBG), long period gratings (LPGs), evanescent field and hollow core optical fiber sensors are mentioned. Examples of recent optical fiber sensors for the measurement of strain, temperature, displacement, air flow, pressure, liquid-level, magnetic field, and the determination of m...
