Light weight is one significant pursuit for microwave absorption (MA) materials. Generally, constructing foams with porous structure and low density as the absorber efficient way to reduce content quality of MA materials since can effectively cause multiple reflections electromagnetic waves enhance performance. Herein, we report a new simple method fabricating ultralight Ti3C2Tx by hydrochloric...

Abstract Aluminum foam is a kind of new material with large number holes distributed in aluminum alloy. It has the characteristics lightweight, sound absorption, energy absorption and vibration reduction, other porous materials. good acoustic performance. However, its excellent ability only reflected middle high-frequency bands. Besides, low-frequency very poor frequency band narrow. Therefore,...

New systems are required for optical limiting against broadband laser pulses. We demonstrate that the association of non-linear scattering from single-wall carbon nanotubes (SWNT) and multiphoton absorption (MPA) from organic chromophores is a promising approach to extend performances of optical limiters over broad spectral and temporal ranges. Such composites display high linear transmission a...

Operating at the core of the highly-available ZooKeeper system is the ZooKeeper atomic broadcast (Zab) for imposing a total order on service requests that seek to modify the replicated system state. Zab is designed with the weakest assumptions possible under crash-recovery fault model; e.g., any number even all of servers can crash simultaneously and the system will continue or resume its servi...
