Article Correlation Between Fragility and Microstructure in Organic-Inorganic Nanocomposites was published on June 1, 1996 in the journal Science and Engineering of Composite Materials (volume 5, issue 2).
This article describes the historical background of Cem-FIL. Alkali Resistant Glass Fibre, as well as the composite characteristics of the element they generate: GRC. The most important advantages and properties of this type of Composite Material are also detailed.
Abstract Palygorskite and associated clay minerals have been studied in a Pleistocene calcrete complex from the Negev desert (Sde Boqer, Israel). This complex is divided into five main parts: the chalky and marly bedrock overlain by its weathered product, a brecciated calcrete hardpan; the laminar crust; loess pockets…
We performed inelastic neutron scattering measurements on nanophase Fe powders prepared by high-energy ball milling. Neutron energy loss spectra were measured for two states of the material: (1) as milled, when the material had a characteristic nanocrystallite size of 12 nm; and (2) annealed, when the material had a c…
Porcelainized stoneware is an extremely hard and homogeneous unglazed ceramic material obtained by fastfiring of kaolinitic ceramic bodies containing a large amount of fluxes. The obtained tiles, available in a large variety of colours, shape size and surface finish, are characterized by very low porosity (<0,3wt% exp…
Glass fibers in the shape of wool were obtained at laboratory scale from three samples of basaltic rocks from the Tenerife Island. The rockwool is widely used as thermal and acoustical insulation. The ability of these rocks to be fiberized was studied by means of the viscosity curves and can be quite improved by addin…
Explains the fused deposition process and examines the rationale behind the cooling process model. Outlines the complexity of the problems and characteristics of fused deposition. Presents a general formulation for road cooling followed by results and their implications. Concludes with proposed directions for future w…
A portable mechanical tester is described which is both lightweight and cheap to produce. The machine is simple and convenient to operate and requires only a minimum of personnel training. It can be used to measure the fundamental mechanical properties of pliant solids, particularly toughness (in the sense of `work of…
A statistical mechanical integral equation theory is developed to describe the average structure of a polar liquid around a complex molecular solute of irregular shape. The integral equation is formulated in three-dimensional Cartesian coordinates from the hypernetted chain (HNC) equation for a solute at infinite dilu…
The butanolic fraction (BT-II) derived from the aqueous crude extract was prepared from aerial parts of Baccharis trimera and assessed in anti-inflammatory, analgesia, and ulcerogenesis models. Intraperitoneal pretreatment with lyophilized BT-II, at doses ranging from 40 to 100 mg/kg, markedly inhibited carrageenan- a…
Several experiments were conducted in ASDEX Upgrade to prove the suitability of tungsten as a divertor target material under the conditions of a high density and low temperature divertor. The observed fluxes from a tungsten tile into the plasma are low, in keeping with the extremely low sputtering yields. In addition,…
SUMMARY A unified thermodynamic constitutive model for Shape Memory Alloy (SMA) materials, based on the thermodynamic framework proposed by Boyd and Lagoudas,1is presented in this paper. The specific selections for the form of Gibbs free energy associated with the martensitic volume fraction are identified for several…
