Nano-Filament Field Emission Cathode Development Final Report CRADA No. TSB-0731-93

Tony Bernhardt、USDOE、Ted Fahlen2018-01-17OpenAlex

At the time the CRADA was established, Silicon Video Corporation, of Cupertino, CA was a one-year-old rapidly growing start-up company. SVC was developing flat panel displays (FPDs) to replace Cathode Ray Terminals (CRTs) for personal computers, work stations and televisions. They planned to base their products on low…

Estudo comparativo da resistência à corrosão e permeabilidade do hidrogênio de aços API grau X65 baixo manganês em solução B da norma NACE TM-0284.

Juan David Santos Martinez2018-01-17OpenAlex

\n Aços de alta resistência e baixa liga (ARBL) têm sido bastante utilizados na fabricação de tubulações para o transporte de petróleo e gás. Entretanto, o uso destes materiais em meios com elevadas concentrações de H2S, denominados sour, tem resultado em falhas frequentes, devido à suscetibilidade destes materiais ao…

Polyurethane/Multi-Wall Carbon Nanotubes Composites for Microwave Applications

Dassault Aviation, 92552 Saint-Cloud, France、Quentin Clément2018-01-17OpenAlex

Page 3 of 3The absorption efficiency of the functionalized CNT composites can then be compared to those of the basic CNT composites.The results are shown in Figure 4 and we see that the increase of the loss tangent enables to lower the reflectivity and so to enhance the absorption efficiency.As expected, the cobalt-co…

Finite element analysis of three-point bending of a T-beam structural biaxial highly oriented polymer material

Ching-Long Wei、Ho Chang、Yi-Chang Lee 等 6 位作者2018-01-17Polimery

Polymers with biaxial aligned molecular chains are also orthotropic materials, which are characterized by high tensile strength and low shear strength in the length direction. When orthotropic materials are used as structural shapes with poor shear strength, they are likely to undergo premature failure under shear str…
