Fiber angles

Polycyclic aromatic hydrocarbons (PAHs) are common and persistent environmental pollutants produced during the incomplete combustion of fuels. They are known for their carcinogenic and mutagenic properties. Thus, their removal from water bodies is highly crucial and has become a critical issue globally. As a solution, here an electrospun polycaprolactone (PCL) membrane with a mean fiber diameter of 2.74 ± 1.3 μm was produced by electrospinning. Water contact angle (WCA) analysis confirmed the hydrophobic nature of the PCL membrane with a WCA of 124°, which remained stable over time.

Superhydrophobic nanocomposite coatings for magnesium surfaces with remarkable corrosion resistance were fabricated by electrospinning in the presence of fluorosilane-functionalized silica (SiO2) nanoparticles. The effects of surface-modified silica (mod-SiO2) nanoparticles on the superhydrophobicity and corrosion resistance of polystyrene (PS)/mod-SiO2 fiber coatings were evaluated. The incorporation of the SiO2 nanoparticles endows PS fibers with rough surfaces exhibiting a water contact angle (WCA) of 165◦C.

This paper proposes an optimization procedure for maximization of the biaxial buckling load of laminated composite plates using the gradient-based interior-point optimization algorithm. The fiber orientation angle and the thickness of each lamina are considered as continuous design variables of the problem.

The displacement field is based on classical beam theory. Both plane stress and plane strain state are used to achieve constitutive equations. The governing equations are derived from Lagrange’s equations. Ritz method is applied to obtain the critical buckl. ing loads of thin-walled beams. Numerical results are compared to those in available literature and investigate the effects of fiber angle, length-to-height’s ratio, boundary condition on the critical buckling loads of thin-walled channel beams

In this study, the air-plasma generated by radio-frequency was used to treat bamboo fiber. The treatment parameters were studied to find the suitable condition. The testing on tensile strength, tensile modulus, module Weibull and elongation to break of the fiber, the measurement of contact angles and the SEM analysis showed that at the high frequency of 12 kHz, power 50 W and treatment time of 5 minutes, after air-plasma treatment the tensile strength and tensile modulus of bamboo fiber increased more than double (101.1% and 101.

The chemical modification of bamboo fiber using acetic anhydride has been investigated. Three characterisation technique, namely FTIR, SEM, and contact angle, were used to elucidate the effect of the chemical treatment on the fibers. Modified bamboo fiber has been used as reinforcement for polypropylene (PP) and maleic anhydride grafted polypropylene resins.

Physical and mechanical properties of several bamboo species have been studied extensively. Chapter 3 presents the fiber length distribution of Phyllostachys pubescens at different age, layer and location. Contact angle of different layers of the bottom portion of three year old bamboo were measured by dynamic contact angle measurement. Specific gravity and bending properties of bamboo at different ages, horizontal layers, and height locations were also determined. Also compressive strength at different ages and height locations were determined.

To install an inexpensive pinning device in a double hung window, drill a 3/ 16" hole from the inside window sash halfway through the outside sash at a slight downward angle. Then insert a nail or pin into the hole to secure the window. If the sash is wood, the pin can be made of such length as to set flush with the sash. A magnet kept nearby can then be used to remove the pin. The occupant must remember, however, that room windows are often used as a means of escape from burning buildings and at least one window in each room should be available for...

Generally the term photonic crystal refers to two dimensional (2-D) and three dimensional (3-D) structures. Using 2-D and 3-D photonic crystals it is possible to control the propagation of light at arbitrary angles of incidence and not only the light normally incident as is the case for conventional optical films. Further, using photonic crystals, it is possible to achieve optical functionality not possible using conventional optical materials. This book provides a complete overview about photonic crystals including properties, applications, approaches and methods for the study....

The effects of micronization methods, mechanical and jet millings, on the physico-chemical properties of mushroom (Lentinus edodes) powder were investigated in contrast to shear pulverization. The powders of dried mushroom cap and stipe were prepared to obtain six powders. Compared to shear pulverization, mechanical and jet millings effectively reduced particle size and brought about a narrow and uniform particle size distribution.

Abstract: Recent wide-scale deployment of APC connectors in the outside plant for FTTH initiatives has forced connector manufacturers to consider reliability issues of these connectors. Angled connectors exhibit two phenomena not found in non-angled connectors: First, the lower ferrule endface radius of angled connectors makes the connector more susceptible to permanent fiber withdrawal at elevated temperatures. Second, any rotation of the ferrule in angled connectors will increase the apex offset of the connector.

Fiber-to-the-premise architectures, by their very nature, require numerous fiber connections for distribution of services to multiple home and business locations. Much of the connectorization takes place downstream from the central office in the outside plant (OSP) portion of the network, traditionally a splice-only environment.

In order to achieve good reflectance performance through environmental and stress conditions seen in service, fiber-optic connectors must achieve and maintain physical contact between fiber cores. It is a given in the industry that ferrule endface geometry is critical to maintaining fiber core physical contact. The three critical attributes of endface geometry for physical contact (PC) connectors are radius of curvature, fiber protrusion/ recession, and apex offset. In angled physical contact (APC) connectors, the equivalent of apex offset is often referred to as dome offset....

The choice between angle-polished connectors (APCs) and ultra-polished connectors (UPCs) can make a significant impact on how a particular network will perform. There are several considerations to make, including the network design or purpose and the types of services that will be transported over the fiber. This paper will compare and contrast these two categories of connectors, highlighting their differences in terms of physical appearance, insertion loss and return loss characteristics, as well as their overall performance in particular applications....
