Most of the basic research on the electrical behavior of CNTs has been carried out on individual or bundle nanotubes. More recently random or oriented CNT networks (CNTN) are emerging as new material for electronic application. We present the fabrication of thick and dense CNTNs, in the form of freestanding films, and the study of their electric resistance as a function of the temperature, from...
Inclusion-initiated fracture in high-strength spring steel is studied for axial and torsion very high cycle fatigue (VHCF) loading at load ratios of R = −1, 0.1 0.35. Ultrasonic S-N tests are performed with SWOSC-V featuring intentionally increased numbers sizes non-metallic inclusions. The limit considered the threshold mode I cracks starting internal influence inclusion size Vickers hardness ...
This study demonstrates the possibility of depositing metals onto low-metal content particles via impact electrochemistry, a technique used to measure transient current signals (electrochemical impacts) produced from collision between moving under Brownian motion and potentiostated interface (Rees, 2014; Markham et al., 2020; Zhang Zhou, 2020). The deposition copper surface fly-ash cenospheres ...
This paper presents aspects regarding the construction of couplings with bolts using non-metallic elements, e.g. rubber, having different hardness, the elements involved in torque transmission, in this case elastic elements, having also different dimensions or forms, in the way to have a good elasticity and capacity of vibration absorbtion. In paper there are also presented: the construction of...
Identification and characterization play an essential role in the study of non-metallic inclusions (NMIs) monitoring steel casting process product quality. This uses Raman spectroscopy, a versatile, relatively fast, non-destructive technique for characterizing oxide sulfide-based inclusion phases samples. The relative peak intensities positions were used to qualitatively estimate Al2O3, CA, C12...
