Aging Resistance Evaluation of an Asphalt Mixture Modified with Zinc Oxide

Infrastructures
The phenomenon of the oxidation and aging of asphalt binders affects the strength and durability of asphalt mixtures in pavements. Several studies are trying to improve the resistance to this phenomenon by modifying the properties of the binders with ...

Auto-oscillation threshold, narrow spectral lines, and line jitter in spin-torque oscillators based on MgO magnetic tunnel junctions

, 2008
We demonstrate spin torque induced auto-oscillation in MgO-based magnetic tunnel junctions. At the generation threshold, we observe a strong line narrowing down to 6 MHz at 300K and a dramatic increase in oscillator power, yielding spectrally pure ...

Study on Antiaging Performance of Graphene Oxide–Modified Guss Asphalt

Advances in Materials Science and Engineering
The mixing temperature of the guss asphalt mixture is generally 220°C–240°C during production, and the mixture needs to be heated and stirred during transportation, which puts forward higher requirements for the antiaging ability of asphalt.

Aging behavior of Au-based ohmic contacts to GaAs [PDF]

Gold based alloys, commonly used as ohmic contacts for solar cells, are known to react readily with GaAs. It is shown that the contact interaction with the underlying GaAs can continue even at room temperature upon aging, altering both the electrical ...

Bonding Durability Evaluation of Polymer-Modified Emulsified Asphalt Microsurfacing

Advances in Materials Science and Engineering
At present, there are few research studies on the durability of microsurfacing. To further improve the service quality and durability of microsurfacing, five kinds of polymer-modified emulsified asphalt were used to prepare microsurfacing mixture.
