Optical Fiber Probe for Viscosity Measurements

26th International Conference on Optical Fiber Sensors, 2018
An optical fiber probe was developed for viscosity measurements. The sensor acts as a two-wave interferometer, sensible to the position of the fluid inside the cavity. Viscosity is measured through the fluid evacuation velocity.

Design of viscosity-matched optical fibers

IEEE Photonics Technology Letters, 1992
An optical fiber with a homogeneously viscous cross section can be designed for an arbitrary index profile by utilizing two kinds of dopant which have different effects on host material viscosity. Examples of designs are shown for silica-based fibers when GeO/sub 2/ and F are used as the dopants. >

Non-newtonian viscosity of fiber suspensions

Mechanics of Composite Materials, 1991
It has been established that the introduction of fibers not only increases the viscosity of the matrix (a Newtonian liquid), but also leads to dependence of the viscosity on the shearing stress a viscosity anomaly [1-3]. At certain concentrations of monodisperse fibers and with certain viscosities of the matrix, a viscosity "superanomaly" has appeared,

Tuning hardness of swollen viscose fibers

Bioinspired, Biomimetic and Nanobiomaterials, 2014
Viscose fibers are man-made, regenerated cellulose fibers. They offer versatile uses ranging from hygiene articles to textiles and medical applications. The great advantage over natural pulp and cotton fibers are the possibilities to design the fibers’ cross-sections and modify the material by directly mixing additives to the viscose dope.

Fabrication of oxidized sodium carboxymethylcellulose from viscose fibers and their viscosity behaviors

Fibers and Polymers, 2013
The oxidized sodium carboxymethylcellulose (O-CMC) fibers have been successfully synthesized via the oxidation-etherification method. Subsequently, the O-CMC fibers are characterized by Fourier transform infrared (FT-IR), 13C nuclear magnetic resonance (13C-NMR) and X-ray diffraction (XRD).

Investigating the Biodegradation Potential of Viscose Fiber

2023
Fibres are considered biodegradable when they can be naturally decomposed, either in the presence of oxygen (aerobically) by microorganisms into carbon dioxide, water, mineral salts, and biomass, or in the absence of oxygen (anaerobically) into carbon dioxide, methane, mineral salts, and biomass.

Viscosity of fiber preloads affects food intake in adolescents

Nutrition, Metabolism and Cardiovascular Diseases, 2009
Dietary fiber that develops viscosity in the gastrointestinal tract is capable of addressing various aspects of food intake control. The aim of this study was to assess subsequent food intake and appetite in relation to the level of viscosity following three liquid preloads each containing 5 g of either a high (novel viscous polysaccharide; NVP ...

RESEARCH ON THE SPECIFIC VISCOSITY OF SEMI-CONCENTRATED FIBER SUSPENSIONS

Modern Physics Letters B, 2008
The viscosity properties of the semi-concentrated suspensions of fibers with small aspect ratio were investigated in transient shear flow using a concentric cylinder geometry. Experimental results were compared with predictions by utilizing the constructive model developed by Batchelor in conjunction with the hybrid closure proposed by Advani and ...

Viscosity-matched single-mode fibers

1999 IEEE LEOS Annual Meeting Conference Proceedings. LEOS'99. 12th Annual Meeting. IEEE Lasers and Electro-Optics Society 1999 Annual Meeting (Cat. No.99CH37009), 2003
We reviewed the viscosity characteristics and scattering characteristics of silica glasses. We also reviewed the viscosity-matching technique. This technique is very promising for realizing low-loss fiber where the difference between core and cladding viscosities is relatively large.

Preparation and Characterization of Activated Carbon/Viscose Fiber

Applied Mechanics and Materials, 2015
Viscose fibers (VF) are widely used because of its good bio-compatibility and the adsorbent performance. In this paper, adsorbent fibers were obtained via wet spinning method with the mixed solution of activated carbon dispersion and viscose. The characterization of activated carbon/viscose fibers (ACVF) were evaluated by infrared spectroscopy (IR ...
