Chalcogenide microfiber-assisted silica microfiber for ultrasound detection
Optics Letters, 2020An ultra-compact ultrasound sensor with a chalcogenide (ChG) microfiber and a silica microfiber is fabricated. It can detect the ultrasound wave generated by a piezoelectric transducer peaked at 3.7 MHz. The sensor shows the broadband ultrasound frequency response with a high signal-to-noise ratio (SNR), owing to the high refractive index and small ...

Heterotypic microfibers have been recognized as promising building blocks for the multifunctionality demanded in various fields, such as environmental and biomedical engineering. We present a novel microfluidics-based technique to generate bio-inspired microfibers with hourglass-shaped knots (named hourglass-shaped microfibers) via the integration of a

Effects of synthetic and natural microfibers on Daphnia magna–Are they dependent on microfiber type?
Aquatic Toxicology, 2021Microfibers, which are sourced from textiles and some products from the fishery industry, are the biggest contributors to microplastic pollution in aquatic ecosystems. In addition to these synthetic microfibers, naturally derived microfibers can also be found in aquatic environments.

Magnetospinning of Nano‐ and Microfibers
Advanced Materials, 2015Magnetospinning is a new method for spinning of continuous micro- and nano-fibers using a permanent revolving magnet. The method utilizes magnetic forces and the hydrodynamic features of stretched threads to produce highly loaded, fine magnetic nanofibers.

Control of the length of microfibers
Lab on a Chip, 2012Uniform polymeric microfibers of prescribed lengths were synthesized in microfluidic devices using two different approaches--valve actuation and pulses of ultraviolet (UV) light. The more versatile valve approach was employed to demonstrate control of the length of the microfiber as a function of the frequency of valve actuation.

Effect of Microfiber Length on Microfiber Motion in Human Nasal Airways
Volume 2: Multiphase Flow (MFTC); Computational Fluid Dynamics (CFDTC); Micro and Nano Fluid Dynamics (MNFDTC), 2022Abstract Respiratory inhalation of elongated mineral particles has been a significant concern for humans due to the adverse health consequences. In recent years, the increased usage of carbon nanofiber and carbon nanotubes in high-performance engineered materials has raised renewed concerns.

Optical microfibers and microfiber resonators
2009 11th International Conference on Transparent Optical Networks, 2009Microfiber waveguide, microfiber loop resonator, and microfiber coil resonator are the basic elements of microfiber photonics. The interest in photonic devices fabricated of microfibers is caused by their small transmission losses and potential ability of micro-assemblage in 3D.

Most composites are fabricated at elevated temperatures and cooled to room temperature. The difference in coefficients of thermal expansion of the fiber and matrix may cause buckling of the slender-shaped microfibers. This would greatly reduce the initial strength of the composites.

Optical data storage in microfibers
Optics Letters, 1998Tests of optical data storage in arrays of microfibers confirm its applicability and potential for higher storage densities than those achievable with conventional holographic data storage. Arrays of single-mode microfibers, spaced 0.78 microm apart and 60 microm long, were generated in a photopolymer film with four laser beams and simultaneously ...
