Mechanical and Impact Properties of Untreated Jute Fabric Reinforced Polyester Laminates Compared With Different Ε-Glass Fibre Reinforced Laminates
Article Mechanical and Impact Properties of Untreated Jute Fabric Reinforced Polyester Laminates Compared With Different Ε-Glass Fibre Reinforced Laminates was published on December 1, 2000 in the journal Science and Engineering of Composite Materials (volume 9, issue 4).

Material’s Volumetric-Flow Rate (MVR) as a Unification Parameter in Asphalt Rheology and Quality Control / Quality Assurance Tool for High Temperature Performance Grading
Rheological data of unmodified and polymer-modified asphalts are conventionally obtained from dynamic mechanical characterization and expressed in terms of sets of curves showing the variation of viscoelastic properties with frequency. Using the conventional melt flow indexer, the material’s volumetric-flow rate MVR (…
Recycling of the Granite Quarries and Municipal Incinerator Wastes for the Processing of New Materials as Porcelainized Stoneware
In the 1980s started in the ceramic sector the material conception of porcelainized stoneware, a product with versatile and modern characteristics similar to those of the natural stone, depicting improved properties to the marble and granite. Porcelanized stoneware is a compact ceramic material, very hard and homogene…
Transient Measurements in Rate Controlled Rheometers: A New Method of Standardization
Rheological measurements in response to transient shear rate exhibit coupling effects between mechanical characteristics of rheometer and unsteady (thixotropic and viscoelastic) properties of fluid. This coupling is observed if the characteristic times of the latter lie in the range of those associated to mechanical p…

Evaluation of the penetration of restoration materials in stone. A new method
We have used the measurements of the water-stone contact angle on the surface of sections of biocalcarenite samples to evaluate the penetration of organic and silico-organic restoration products in this rock. The method has been found to be effective and precise, allowing us to distinguish the depth of the zone with w…

Strong Mechanoluminescence from UV-Irradiated Spinels of ZnGa2O4:Mn and MgGa2O4:Mn
The mechanoluminescence (ML) from spinels of MgAl 2 O 4 :Mn (MAO:Mn), MgGa 2 O 4 :Mn (MGO:Mn) and ZnGa 2 O 4 :Mn (ZGO:Mn) has been investigated. It was found that the MGO:Mn and ZGO:Mn gave a strong ML response and a long-lasting phosphorescence (LLP). On the contrary, MAO:Mn exhibited very weak ML and no LLP. The hig…
Thermoelectric Properties of Bi2.3-xPbxSr2.6Co2Oy Single Crystals
A set of single crystals of the layered cobaltite Bi 2.3- x Pb x Sr 2.6 Co 2 O y (0 ≤ x ≤0.44) were prepared by a flux technique. The resistivity ρ and the thermopower S along the in-plane direction were measured, and the thermoelectric properties were compared with those of other oxides. The Pb substitution causes a…
First-principles study of ferroelectric and antiferrodistortive instabilities in tetragonalSrTiO3
We carry out first-principles density-functional calculations of the antiferrodistortive (AFD) and ferroelectric (FE) soft-mode instabilities in tetragonal ${\mathrm{SrTiO}}_{3},$ with the structural degrees of freedom treated in a classical, zero-temperature framework. In particular, we use frozen-phonon calculations…
Towards better integrators for dissipative particle dynamics simulations
Coarse-grained models that preserve hydrodynamics provide a natural approach to study collective properties of soft-matter systems. Here, we demonstrate that commonly used integration schemes in dissipative particle dynamics give rise to pronounced artifacts in physical quantities such as the compressibility and the d…
A Novel Iron-Based Catalyst for the Biphasic Oxidation of Benzene to Phenol with Hydrogen Peroxide
Improved selectivity and decreased formation of overoxygenated byproducts were achieved by using a MeCN/H2O biphasic system for the iron-catalyzed oxidation of benzene to phenol with H2O2. Under optimized reaction conditions with 5-carboxy-2-methylpyrazine-N-oxide as the ligand for iron [Eq. (1)] a benzene conversion…
Formation of Mixed Fibrils Demonstrates the Generic Nature and Potential Utility of Amyloid Nanostructures
The aggregation of proteins and peptides in the form of stable and highly ordered amyloid fibrils is most commonly associated with pathological conditions such as Alzheimer's disease and the transmissible spongiform encephalopathies. The involvement of only a handful of proteins in amyloid formation in vivo has common…
Modelling sublimation and atomic layer epitaxy in the presence of competing surface reconstructions
We present a solid-on-solid model of a binary AB compound, where atoms of type A in the topmost layer interact via anisotropic interactions different from those inside the bulk. Depending on temperature and particle flux, this model displays surface reconstructions similar to those of (001) surfaces of II-VI semicondu…
