Experimental Study on Deicing Performance of Carbon Fiber Reinforced Conductive Concrete

Zuquan TANG , Zhuoqiu LI , Jueshi QIAN , Kejin WANG

材料科学技术（英文）

Carbon fiber reinforced concrete (CFRC) is a kind of good electrothermal material. When connected to an external power supply, stable and uniform heat suitable for deicing application is generated in the CFRC slab. Electric heating and deicing experiments of carbon fiber reinforced concrete slab wer...

Molecular dynamics studies on vacancy-interstitial annihilation in silicon

Acta Physica Sinica

Molecular dynamics (MD) simulation is performed to study the vacancy-interstitial annihilation in crystalline silicon. We choose the Stillinger-Weber potential, which is commonly used for silicon, to describe the interaction between atoms. The system is relaxed under 300K and 1400K respectively. We ...

ELECTRONIC-PROPERTIES OF ONE-DIMENSIONAL QUASI-LATTICES

Zeitschrift Fur Physik B-Condensed Matter

we study the on-site model of a new class of one-dimensional quasiperiodic lattices, for which the substitution rules are B --> BA, and A --> BAB. By means of the renormalization-group approach, a interesting multifractal spectral behavior has been found, which has been confirmed by numerical ...
