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.

Journal of Applied Mechanics, 1967
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.

Janus-Core and Shell Microfibers
Langmuir, 2013Janus microcylinders composed of different polymers were prepared through coaxial co-jetting with dual-core flows, followed by cross-linking, microsectioning, and shell removal. Uniquely shaped building blocks can be fabricated by photo-patterning of one hemisphere of the microcylinders.

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 ...

Reef Knot Microfiber Resonators
Asia Optical Fiber Communication and Optoelectronic Exposition and Conference, 2008We propose a new way to realize a microresonator by making a reef knot with two microfibers. We demonstrate an all-silica reef knot resonator and discuss the first steps towards hybrid silica-chalcogenide resonators.

Neonatal ophthalmoplegia with microfibers
Neurology, 1977An infant born with marked hypotonia showed prompt regression of skeletal muscle weakness, but by 7 weeks of age had total external ophthalmoplegia. Biopsy of the gluteus muscle at 14 days showed marked variation in fiber size with a large proportion of very small fibers (less than 3 mu).

Observation of a nonlinear microfiber resonator
Optics Letters, 2008Measurements of the intensity transfer function of a silica microfiber resonator are shown to follow a wide variety of hysteresis cycles, depending on the cavity detuning and the scanning frequency of the range of input powers. We attribute these observations to a nonlinear phase shift of thermal origin and provide a simple model that reproduces well ...

Highly birefringent silica microfiber
Optics Letters, 2010A highly birefringent silica microfiber was successfully developed by adiabatically tapering a low-birefringence flat fiber at a low temperature. Owing to the high fiber cross-sectional ellipticity and the large refractive index contrast between silica and the surrounding air (deltan=0.45) the flat microfiber provides an extremely high group ...
