This document provides guidelines for selecting suitable tabbing configurations for composite material test specimens. Additionally, a practical methodology is detailed for preparing and applying tabs to composite test specimens. This document is based on research performed within the Mechanical Engineering Department…
Isomerically pure samples of α1-P2W17O61M were prepared, in which M represents CaII and mainly the first-row transition metal cations: MnII, FeIII, CoII, NiII, CuII, ZnII. The formula is α1-P2W17O62M for VV and MoVI. The compounds were characterised by elemental analysis, IR, UV/Vis and 31P NMR spectroscopy. The stabi…
The formation of pentagonal defects and bamboo-like structures in carbon nanotube (NT) growth is viewed within the framework of the surface diffusion (SD) growth model. NT open edge stability is considered as a competition between: (i) hexagon formation which depends on the rate at which C units are fed by SD to the e…
This article surveys the physiological impact of waterproof textiles on the wearers of protective clothing. Wearer trials with test subjects in a climatic chamber involve ambient temperatures of +20. 0, and -20°C. The physiological function of breathable materials in comparison to a water vapor impermeable constructio…
A new series of liquid crystalline main chain copolyesters were prepared, having ferrocene in the mesogenic segment and a methyl phosphate group along with a methylene spacer. The even numbered methylene groups were varied from two to ten. Liquid crystalline behaviour was investigated on a hot stage optical polarized…
The electrochemical dissolution behaviour of armco-iron and of the steels C15, C45, C60 and 100Cr6 in concentrated sodium chloride media has been investigated. Anodic metal dissolution experiments have been carried out using the flow channel cell (parallel plate reactor), the rotating cylinder electrode (RCE) and the…
Chemical vapour deposition (CVD) diamond is known for its excellent chemical, mechanical and thermal properties, as well as low or negative electron affinity. These unique characteristics make CVD diamond a good material as an electron emitter. In this study, electron field emission has been measured from nano-, submi…
Abstract Volcanic tuff from the Cabo de Gata region in Almería, southeastern Spain, was altered under hydrothermal conditions at different temperatures (60 to 180°C), reaction times (60 to 360 days), and reacting solutions (deionized water and NaCl and KCl solutions with Na/K ratios from 0.01 to 100, and a total salt…
Li has been theoretically predicted to be a shallow donor in diamond in interstitial sites. Many experimental works have investigated the possibility to incorporate Li into diamond to obtain n-type electrical conductivity related to Li doping. The results of these researches are somewhere inconsistent. In this work, t…
E25 has been applied in our studies in order to find optimal culture conditions for effective bacterial cellulose (BC) production. The strain displays significantly higher stability in BC production under stationary culture conditions. In contrast, intensive agitation and aeration appear to drastically reduce cellulos…
XPS (X-ray Photoelectron Spectroscopy) or ESCA (Electron Spectroscopy for Chemical Analysis) as a surface analytical technique has been developed over years and has been used successfully in characterization of a variety of thin films. Information such as composition, chemical states, depth profile, imaging and thickn…
This paper reports an experimental investigation of the effect of repeated laundering on the comfort-related and low stress mechanical properties of polo shirt fabrics with and without wrinkle-free treatments. Comparisons are made of untreated fabrics, fabrics treated with a hydrophobic wrinkle-free treatment, and fab…
Investigation of the impact behaviour of Hadfield steel has been carried out in a broad range of strain rates from 10 −3 to 9 × 10 3 s −1 by means of a servo-hydraulic machine and a compressive split Hopkinson bar. The effects of strain rate on the impact properties, substructure evolution and fracture resistance have…
The stress corrosion cracking (SCC) behavior of cold-worked and sensitized Type 304 (UNS S30400) stainless steels has been evaluated using the slow strain rate test. Tests were carried out in an aqueous solution of 1 N sulfuric acid (H2SO4) + 0.5 M sodium chloride (NaCl) at 30°C under various potentiostatic conditions…
Conventional methods that are used to overcome multidrug resistance (MDR) often involve the coadministration of chemosensitizers and anticancer drugs. However, coadministration of many chemosensitizers with anticancer drugs, such as doxorubicin (Dox) has resulted in the exacerbation of anticancer drug toxicity. Here,…
Solid solutions of Sr 9+ x Ni 1.5 - x (PO 4 ) 7 that are structurally related to β-Ca 3 (PO 4 ) 2 are formed in the compositional range of 0.14 ≤ x ≤ 0.39. We investigated static disorder in Sr 9.3 Ni 1.2 (PO 4 ) 7 ( x = 0.3, space group: R 3̄ m ) by X-ray and neutron powder diffraction. The electron-density distribut…
Abstract A novel cage complex [Cu6Cl(MeO)2(pz)9] (1) was synthesized via a chloride ion template reaction and structurally characterized. In 1, two trinuclear units, {Cu3(MeO)(pz)3}2+, are linked by three pyrazolate ligands, six copper(II) ions form a trigonal prism, and a chloride ion is located at the center of the…
In order to study the wearing comfort of pressure for tight‐fit clothing, the sensation of wearing pressure and the other related sensations have been assessed for knit garments, which have different sizes and fabrics which have different extensibilities, by developing a wearing experimental procedure. Using factor an…
Abstract Poly(ethylene‐ co ‐vinyl acetate) (EVA) powders containing 10 and 20 wt % of vinyl acetate (VAc) units was saponified in ethanol/KOH solution in a heterogeneous manner. Intermolecular interaction between vinyl alcohol(VOH) units in the produced poly(ethylene‐ co ‐vinyl alcohol) (EVOH) promoted the crystalliza…
Abstract A flexible computational model for the initiation of crevice corrosion has been developed. Based upon a mechanistic theory, empiricisms do not limit the scope of this work. The model is formulated in a previous paper and this sequel publication showcases the performance of the algorithm. Designed for widespre…
