A novel addition-type liquid silicone rubber (AL-SR) adhesive has been prepared by incorporation of organic montmorillonite (OMMT). Physico-mechanical properties, such as adhesion, tensile strength and thermal stability, were investigated and compared to aerosilica (also known as pyrogenic silica) filled systems. Resu…
In the heat-transfer analysis of a solidification process, the effective specific heat method is conceptually simple to apply while dealing with the latent heat problem. The implementation of computer program is very easy for this method. However, in a time step, if a nodal temperature enters, leaves or jumps over the…
A review is given of the strategies used to dope inorganic solids and the consequences for properties such as ionic and electronic conductivity. Doping mechanisms involve either substitution of foreign ions onto lattice sites, creation of vacancies on either cation or anion sites, or population of normally empty inter…
The energy storage potentials of many different carbon nanotube (CNT) materials are investigated electrochemically. The electrochemical response of all the investigated materials is rather featureless during charging and discharging and does not show any phase transitions or clear redox responses. The maximum discharg…
Mixed Ionic–Electronic YSZ/Ni Composite for SOFC Anodes with High Electrical Conductivity, Fonseca, Fabio C., de Florio, Daniel Z., Esposito, Vincenzo, Traversa, Enrico, Muccillo, Eliana N.S., Muccillo, Reginaldo
The sintering behavior of 7.8 mol% Yttria-stabilized cubic stabilized zirconia (Y-CSZ) powders was investigated, with emphasis on the effect of Al2O3 addition at the initial sintering stage. The shrinkage of powder compact was measured under constant rates of heating (CRH). The powder compact with 0.25 mass% Al2O3 enh…
Wormhole-like mesostructured alkali-free borosilicate glasses (MBSGs) with different compositions have been synthesized by a combination of surfactant templating, sol–gel methods and evaporation-induced self-assembly (EISA) processes.
The process of severe plastic deformation (SPD) was applied to Al alloys in order to demonstrate that it is possible to control the morphology and distribution of second phase particles using SPD. Equal-channel angular pressing (ECAP) is used for the SPD process and transmission electron microscopy is used for the mic…
The main contribution of this paper is to show the realizability of epoxy-based nanocomposites as industrial insulating materials. The nano- and micro-filler mixture was invented to boost the nanocomposite in industrial insulating materials. Nano- and micro-filler mixture composites were newly made by dispersing a few…
The commonly used die-cast magnesium alloy AZ91D in chip form bearing different environmental corrosive conditions was compacted, and then extruded in order to assess the feasibility of recycling in solid-state. This recycled material showed no inferior mechanical properties than its un-chipped counterpart. It was als…
Increasing resistivity of copper with scaling and rising demands on current density requirements are driving the need to identify new wiring solutions for deep nanometer scale VLSI technologies. Metallic carbon nanotubes (CNTs) are promising candidates that can potentially address the challenges faced by copper and th…
This work is centered on the study of the corrosion inhibition of copper in 1 M HNO3 by N-phenyl oxalic dihydrazide (PODH) and oxalic N-phenylhydrazide N-phenylthiosemicarbazide (OPHPT) synthesized in our laboratory. The inhibition efficiency obtained by chemical (weight loss) and electrochemical (potentiodynamic pol…
Amide derivatives of L-alanine and ε-caprolactam were readily obtained on diamine-functionalized oxidized single-walled and pristine multi-walled carbon nanotubes through a one-step direct amidation reaction, which employs thermal activation at 160–200 °C instead of chemical activation, avoids the use of organic solve…
The stress that acts on the core by installing a stator in a frame influences the performance of a motor. To reflect this influence in the equipment design, the stress dependence of the magnetic property was examined for non-oriented electrical steels, which are the core materials. This time, the stress dependence of…
The dependence of the nearest neighbor magnetic interaction, JAB, as a function of geometry for [Mn(porphyrin)][TCNE] materials has been evaluated by the results of CASSCF, CASPT2 and B3LYP calculations. The B3LYP results were validated for seven representative [Mn(porphyrin)][TCNE] molecule-based magnets and were fou…
Mechanically robust, hollow carbon nanotube composite spheres that are permeable to large chemical species were prepared by a layer-by-layer assembly and templating technique.
Extraordinary high degrees of polar order can be achieved by a rational design that involves the polar stacking of parallel beloamphiphile monolayers (PBAM). This strategy is exemplified by the acetophenone azines MCA (4-methoxy-4'-chloroacetophenone azine) and DCA (4-decoxy-4'-chloroacetophenone azine). The beloamphi…
Comparative studies of the pulsed laser ablation of graphite in 20mTorr of N2 using both 15ns and 450fs pulses at a wavelength of 248nm are reported. Emissions from the resulting ablation plumes, and from collisions with ablated material and the background N2 gas molecules, have been investigated by wavelength-, space…
It is well known that Si and Mn, the basic alloying elements for steel materials, are susceptible to oxidation and form oxides on the steel surface easily, which has a great influence upon the surface performance of steel sheets such as phosphatability. In recent years, on the other hand, the cold rolled steel sheets…
Abstract: Heterogeneous ruthenium catalysts supported on silica from rice husk ash (RHA-Ru) was prepared by precipitation using an aqueous solution of metal salt in 3.0 M HNO 3 . The effect of calcination at high temperature upon the surface and bulk structure of the catalyst precursor has been investigated. X-ray dif…
