Evaluation of Particle Size and Particle Shape Distributions in Al-Al3Ni FGMs Fabricated by a Centrifugal in-situ Method
Preparation and characterization of FeAg granular alloys
Fe10Ag90 granular alloys have been fabricated, using a sol-gel method, for a range of nitric acid concentrations in the start solution. The samples have been characterized by X-ray diffraction and magnetization measurements. The average Fe particle sizes derived from X-ray diffraction are in the range 24-29 nm, indica…
Synthesis and preliminary characterization of octakis (chloropropyldimethylsiloxy) octasilsesquioxane
Octakis (hydridodimethylsiloxy) octasilsesquioxane was hydrosilated with allyl chloride using Spiers catalyst (H2PtCl6). This reaction was monitored using FT-IR spectroscopy. The synthesized product was characterized by 13C, 29Si NMR (MAS), SEM, FT-IR, Thermogravimetric techniques. The three propyl groups alpha, beta,…
Los Angeles Test and Polished Stone Value of ophite in Cantabria: a petrophysical interpretation
Crushed aggregate obtained from certain ophite outcrops in Cantabria was tested with the Los Angeles and polished stone value (PSV) procedures. Linear regression analysis was used to identify the pétrographie parameters that account for aggregate performance in these two tests. The most abundant and common minerals in…

''Geopolymers": same basic chemistry, different microstructures
The present paper describes the effect of certain working variables on the microstructural evolution of oven-dried, alkali-activated fly ash. The results show that the main reaction product in the activation process (in all the systems studied) is an amorphous aluminosilicate gel with a three-dimensional structure. No…
Thin copolymer-cased light-emitting display made with fluorine-foped tin oxide substrates
Seven-segment displays are used to show numerical quantities in electronic equipment, being present in most of the low-end electronics. In this work we describe a novel organic light emitting display made with poly(1,10 decanedioxy 2 methoxy - 1,2 phenylene - 1,2 ethenylene - 3,6 dimethoxy - 1,4 phenylene - 1,2 etheny…
HPMA and HEMA copolymer bead interactions with eukaryotic cells
Two different hydrophilic acrylate beads were prepared via aqueous suspension polymerization. Beads produced of a hydroxypropyl methacrylate (HPMA) and ethyleneglycol methacrylate (EDMA) copolymer were obtained using a polyvinyl alcohol suspending medium. Copolymers of 2hydroxyethyl methacrylate (HEMA), methyl methacr…
Microstructure and mechanical properties of WC-Co reinforced with NbC
Cemented carbides such as tungsten carbide-cobalt WC-Co composites have been widely used as cutting tool materials. Several reports have shown the influence of different factors such as grain size, type and amount of binder phase and the addition of hard particles on the properties of WC-Co. The purpose of this work w…
The use of a vickers indenter in depth sensing indentation for measuring elastic modulus and vickers hardness
Depth sensing indentation is a powerful experimental technique for determining mechanical properties of materials. In this work a computational routine was developed based on Oliver-Pharr method for measuring a more precise values of elastic modulus using a Fischerscope H100 depth sensing indentation apparatus, with a…

Effect of the deposition conditions of platinum electrodes on their performance as resistive heating elements
The performance of different platinum electrodes used as resistive heating elements was studied. Pt films having different thickness were deposited by RF magnetron sputtering at room temperature followed by post-deposition annealing at 700 ºC or made in-situ at 700 ºC. The Pt films were deposited over oxidized silicon…
