A two-phase flow model is developed to simulate the fiber motion in the nozzle of an air-jet spinning machine. The computational results coincide with the images captured by high-speed photography. Three parameters, the first nozzle pressure, the jet orifice angle, and fiber flexural rigidity, are discussed in terms o…
This study has focussed on three main areas. First, an evaluation of the physical attributes of cashmere tops available to commercial spinners; second, the influence of processing variables on the efficiency of producing cashmere tops from raw Australian cashmere; and third, the influence of design of cashmere ultrafi…
The N-terminal tau 2-19 peptide undergoes gelation, syneresis, and aggregation over a period of years. These changes may be approximated on a shorter time scale by agitation and partial dehydration. The anomalously enhanced (229 nm) ultraviolet resonance Raman (UVRR) imide II band reveals a common structural feature f…
This paper investigates means of exploitation of space charge measurement results in order to achieve information about chemical, physical and microstructural properties of dielectric materials. The derivation of quantities as mean volume density of space charge, threshold for DC space charge accumulation, apparent-tr…
Research on the use of biomaterials as vascular substitutes has been dominated in the past by studies focusing on the properties of the materials used. These need to be resistant to protein absorption and should allow cell colonization and integration of the biomaterial within recipient tissue. Despite promising persp…
A novel method was proposed to produce thermoplastic elastomers containing ground tyre rubber (GTR). The new proprietary technology is based on the fact that bitumen and related materials may contribute to the devulcanisation of GTR and act at the same time as plasticiser and compatibiliser in the blends. Blends conta…
Abstract The thermal behavior of polyamide 6/amorphous polyamide blends has been investigated as a function of blend composition and temperature. Crystal phase nature and stability are probed by a combination of thermal analysis, X‐ray diffraction and Fourier transform infrared spectroscopy. Ductility appears to be st…
Abstract Summary: A novel method was used to prepare poly(propylene)/montmorillonite/calcium carbonate nanocomposites by melt‐mixing, using pristine montmorillonite (MMT), hexadecyltrimethylammonium bromide (C16), calcium carbonate (CaCO 3 ) and a matrix in a twin‐screw extruder. Two different sizes of calcium carbona…
By analysing the physical mechanisms of heat and moisture transfer through textiles with PCM and carrying out the test of thermal regulating functional performance of PCM garment in climate chamber, the thermal regulating functional performance of PCM garments have been analysed and discussed in this paper. Both numer…
Abstract Twelve neutral stable complexes of ytterbium( III ) and erbium( III ) coordinated by anionic hydridotris(pyrazol‐1‐yl)borate and meso ‐tetraphenylporphyrinate, and its derivatives with different substituents in the para position of the phenyl groups, were prepared and characterized. Crystal structure analyses…
A cryogenic treatment (-306°F) was applied to C2 tungsten carbide (WC -6% Co) and compared with untreated carbide to determine if tool wear could be reduced during turning tests with medium density fiberboard (MDF). Both the tool force data and observation of the cutting edges indicate that tool wear was reduced. The…
Abstract The efficiency of heterogeneous nucleation of isotactic polypropylenes (iPP) with various isotacticity and MWD is estimated by an increase of the crystallization temperature ( T cr ). A bi‐component nucleating system, composed of a pimelic acid and a calcium stearate, was added to the polymeric matrix in the…
Abstract The potential of chitosan as a coagulant in commercial tofu preparation was investigated with six chitosans of different molecular weights using various treatments. The following optimum processing conditions for tofu preparation were proposed: chitosan with a molecular weight of 28 kDa; chitosan solution typ…
A room temperature solid-state structural transformation was observed in 3 nm ZnS nanoparticles in methanol following the addition of water (Zhang et al., Nature 424, 1025, 2003). Experimental wide angle x-ray scattering (WAXS), x-ray absorption near edge structure (XANES) and extended x-ray absorption fine structure…
Valve morphogenesis was followed in normal living cells, during treatment with anti-cytoskeletal drugs, and in cells fixed for electron and immunofluoresence microscopy. The long terminal spine-like extrusion is a tubular labiate process (LP). The new valves and LPs were initiated by mid-cleavage. After cytokinesis, t…
A crystalline form of hydrated calcium phosphate, brushite (CaHPO 4 ⋅2H 2 O), has been studied by means of total energy First Principles calculations based on the Density Functional Theory (DFT) approximation. The experimental crystal lattice parameters of this mineral have been reproduced with good agreement. The pow…
Abstract Summary: The influences of short chain branching (SBC) on the melt miscibility of low‐density polyethylene (LDPE) with linear high‐density polyethylene (HDPE) were investigated by rheological methods. Two LDPE resins with different branch contents were blended with the same linear HDPE. Dynamic and steady she…
The heat capacity at constant pressure ( C p ) of mullite (single crystalline and dense and powdered polycrystalline) was determined between −125° and 1400°C. Measurements were performed in three laboratories using two different disk‐type differential scanning calorimeters (DLR and Netzsch) and one cylinder‐type (Seta…
Abstract Electroless plating of copper via a tin‐free activation process was carried out effectively on two types of fluorinated polyimide (FPI) films modified by UV‐induced surface graft copolymerization with N‐containing monomers, such as 1‐vinylimidazole (VIDz) and 4‐vinyl pyridine (4VP). The graft copolymerization…
Abstract In the presence of Ln 3+ (Ln = La, Eu, Gd, Tb, Dy, Ho, Er, Tm or Lu), tris(2‐aminoethyl)amine condensed with three equivalents of 3‐(2′‐pyridyl)‐5‐ tert ‐butyl‐2‐hydroxybenzaldehyde in methanol to give the neutral Schiff‐base complex Ln III L (Ln = La 1 , Eu 2 , Gd 3 , Tb 4 , Dy 5 , Ho 6 , Er 7 , Tm 8 and Lu…
