ABSTRACT: It has been shown by the heat treatment experiments (1350–1500 °C) that the compound Ho2Si2O7 exists in four modifications, a triclinic low temperature phase (type B), a monoclinic modification (type C), a high temperature monoclinic (type D) and a high temperature orthorhombic modification (type E). The X-ray diffraction studies have been used to identify these phases. The lattice constants along with the space groups are reported. Optically clear small single crystals of C- and D-type Ho2Si2O7 have also been prepared by the flux method.Journal of Materials Science Letters 03/2009; 471(s 1–2):432–434.

ABSTRACT: Recently, extensive attention has been paid to the preparation and characterization of copper selenide nanoparticles, owing to their composition’s complexity and wide application in solar cells, as an optical filter and as a superionic material . Various methods have been applied to prepare these important nanocrystals, such as solvothermal method [2, 3], γ -irradiation route , microwave-assisted heating method , sonochemical method [6‐8] and photochemical method . However, only a few studies on the phase control of nanocrystalline copper selenide have been reported. For example, the effect of solvent and surfactant has been investigated in the formation of different phases of nanocrystalline copper selenide by Xie and coworkers  using a sonochemical approach. Therefore, to further study the phase control of nanocrystalline copper selenide with simple process will be interesting. In this letter, we report a complex-assisted photochemical route for the control synthesis of different phases of copper selenide nanocrystals. Compared with changing solvent or surfactant to control the phase of copper selenide, our control synthesis of different phases of copper selenide nanocrystals is by means of complexing agent. Furthermore, in this route, Se 2− source for copper selenide is provided by photochemical method. The formation of copper selenide nanocrystals with different phases in this complex-assisted photochemical route is also discussed. Cu(NO3)2·3H2O, disodium ethylene diamine tetracetate (EDTA-2Na), trisodium citrate (Cit-3Na), triethanolamine (TEA), Na2SO3 and Se powders were of analytical grade, purchased from Shanghai Chemical Reagent Company and used without further purification. Sodium selenosulfate (Na2SeSO3, 0.2 mol/L) was prepared by refluxing the mixture of a 100 mL aqueous solution of sodium sulfite (Na2SO3, 0.6 mol/L) and 0.02 mol Se powders for about 5 h. 0.2 g Cu(NO3)2·3H2 Ow as dissolved into 26 mL deionized water in three 50 mL stoppered quartz conical flasks, respectively. To them, complexing agents (EDTA-2Na, Cit-3Na and TEA) were added with the molar ratio of complexing agent: Cu 2+ ions = 1:1 to form complex solutions. Afte r1h stirring, 0.2 mol/L Na2SeSO3 were respectively added to the complexing solutions to give a final volume of 30 mL and the mixture solutions were purged with nitrogen for 15 min.Journal of Materials Science Letters 12/2003; 22(24):1801-1803.

ABSTRACT: A dynamic fatigue study was performed on a Titanium Silicate glass to assess its susceptibility to delayed failure and to compare the results with those of a previous study. Fracture mechanics techniques were used to analyze the results for the purpose of making lifetime predictions. The material strength and lifetime was seen to increase due to the removal of residual stress through grinding and polishing. Influence on time-to-failure is addressed for the case with and without residual stress present. Titanium silicate glass otherwise known as ultra-low expansion (ULE)* glass is a candidate for use in applications requiring low thermal expansion characteristics such as telescope mirrors. The Hubble Space Telescope s primary mirror was manufactured from ULE glass. ULE contains 7.5% titanium dioxide which in combination with silica results in a homogenous glass with a linear expansion coefficient near zero. delayed failure . This previous study was based on a 230/270 grit surface. The grinding and polishing process reduces the surface flaw size and subsurface damage, and relieves residual stress by removing the material with successively smaller grinding media. This results in an increase in strength of the optic during the grinding and polishing sequence. Thus, a second study was undertaken using samples with a surface finish typically achieved for mirror elements, to observe the effects of surface finishing on the time-to-failure predictions. An allowable stress can be calculated for this material based upon modulus of rupture data; however, this does not take into account the problem of delayed failure, most likely due to stress corrosion, which can significantly shorten lifetime. Fortunately, a theory based on fracture mechanics has been developed enabling lifetime predictions to be made for brittle materials susceptible to delayed failure. Knowledge of the factors governing the rate of subcritical flaw growth in a given environment enables the development of relations between lifetime, applied stress and failure probability for the material under study. Dynamic fatigue is one method of obtaining the necessary information to develop these relationships. In this study, the dynamic fatigue method was used to construct a time-to-failure diagram for polished ULE glass.Journal of Materials Science Letters 11/2003; 22(23):1723-1725.

ABSTRACT: It is known that conventional medical metals such as stainless steel, titanium and its alloy, cobalt-chromium alloy still dominate the orthopaedic markets due to their high strength and toughness, easy storage, and good processibility. Nevertheless, delayed unions (or nonunions), bone atrophy, refracturing after the removal of fracture devices [1, 2], and hypersensitivity , all which are associated with metallic devices and implants encourage researchers to develop alternative materials. Polymer composite materials show great potential in this field. Continuous and chopped fiber-reinforced nonabsorbable polymer composites were applied for fixation of human fractures as early as the 1970s . However, either delamination or relatively low mechanical performance makes them unsuitable for orthopaedic implants. Three-dimensionally (3D) braided fiber-reinforced composites may be the most promising materials for osteosynthesis devices because of their high impact damage tolerance, good fatigue property, superior fracture toughness, potentially cost-efficient manufacturing, reduced material wastage, and so on. In our previous study , unidirectional carbon fiberreinforced monomer casting (MC) nylon (denoted as CL/MC) composites were successfully prepared via an RTM-aided vacuum solution impregnation plus in situ anionic polymerization. In this study, the same technique was employed to prepare three-dimensional carbon fiber reinforced-MC nylon (C3D/MC) composites. The mechanical properties and water resistance of the C3D/MC composites were assessed and compared with those of the CL/MC composites. The reinforcement used in the present study is a highstrength PAN-based carbon fiber (T300) with the following specified properties: tensile strength, 3530 MPa; elastic modulus, 230 GPa; density, 1760 kg m −3 ; diameter, 6‐8 µm. Caprolactam, sodium hydroxide (analytical grade), and toluene diisocynate were used as the monomer, catalyst, and activator, respectively. The preforms, 3D four-directional fabrics, were prepared by the Nanjing Fibreglass R&D Institute, Nanjing, China. The preparation procedure of the C3D/MC composite specimens was similar to that described in reference  except that a higher pressure was applied for 3D fabrics.
