Understanding the thermal budget of perpendicular materials is crucial for the potential application perpendicular magnetic tunnel junctions. In this paper, we study the effects of high-temperature rapid thermal annealing on the structural and magnetic properties of ultra-thin Co/Pd multilayers deposited at room temperature. It is shown that perpendicular magnetic anisotropy of ultra-thin Co/Pd...
1. INTRODUCTION Bridged polysilsesquioxanes(PSSQ) are a family of hybrid organic inorganic materials prepared by sol-gel technology of monomers that contain a variable organic bridging group and two or more trifunctional silyl groups【1-5】. Silsesquioxanes possess high thermal stability and superior mechanical properties and electrical properties. In this study, three types of bridged PSSQ were ...
We review the heuristic arguments suggesting that any thermal quantum field theory, which can be interpreted as a quantum statistical mechanics of (interacting) relativistic particles, obeys certain restrictions on its number of local degrees of freedom. As in the vacuum representation, these restrictions can be expressed by a ‘nuclearity condition’. If a model satisfies this nuclearity conditi...
Solid alkaline fuel cell is employed by polymer anion exchange membrane (AEM) that is permeable to hydroxide ion. A number of polymers have been proposed for AEM which include polysulfone (PSF), poly (phenylene oxide) (PPO), and poly (ether ether ketone) (PEEK). The purpose of this paper was to conduct a critical review on the development of PEEK polymer as AEM, particu...
Polypropylene is extensively used for varied applications due to its low cost, low density, high thermal stability and resistance to corrosion. Enhanced mechanical properties of Polypropylene can be achieved by mixing it with clays to form nanocomposites which increases its utility. Polypropylene Nano composites are formed by mixing polypropylene with calcium carbonate nano particles. This resu...

Negative thermal expansion (NTE) materials have become a rapidly growing area of research over the past two decades. The initial discovery of materials displaying NTE over a large temperature range, combined with elucidation of the mechanism behind this unusual property, was followed by predictions that these materials will find use in various applications through controlled thermal expansion c...
Synthesis and Characterization of Poly(azomethine ester)s with a Pendent Dimethoxy Benzylidene Group
Recently, soluble poly(azomethine ester)s with good thermal stability and liquid crystalline properties are much sought after in opto-electronic field. One such attempt was to synthesize poly(azomethine ester)s with a pendent group. In this study, the newly synthesized diacid monomer benzalaniline 3’-4’dimethoxy terepthalic acid was condensed with two diol monomers to get the polymers with pend...
The thermal insulation properties of barrier coatings (TBCs) can be significantly improved with increasing the coating thickness. However, due to weak bonding high-thickness TBCs, low reliability and short lifetime greatly limits their application under some severe operating conditions. In this study, a novel high-efficiency synchronous dual powder feeding method is used deposit series gradient...
