Most frictional materials used in railways are made of composite material, and their macroscopic material properties largely affected by microscopic structure. It is useful to clarify the relationship between structure numerical simulation for effective improvement or development materials. In this study, we developed an image-based model using X-ray computed tomography a metalized carbon panto...

There is a growing interest in modulating the temperature under the illumination of light. As a heat source, metal nanoparticles (NPs) have played an important role to pave the way for a new branch of plasmonics, i.e., thermo-plasmonics. While thermo-plasmonics have been well established in photo-thermal therapy, it has received comparatively less attention in materials science and chemistry. H...

An optical fiber corrosion sensor (OFCS) based on iron-carbon (Fe-C) film was researched. OFCS was formed by electroplating a Fe-C film on fiber Bragg grating (FBG)metalized with silver film bymagnetron sputtering. There was a more than 430-pm change of FBG wavelength when Fe-C film was seriously corroded. Compared to electrochemical method, the optical fiber sensor shows dominance in long-last...

Abstract: In this paper, a novel integrated high precision vacuum microelectronic accelerometer is put forward based on the theory of field emission, the accelerometer consists of sensitive structure and interface ASIC. The sensitive structure has a mass of a cathode cone tips array, a folded beam, an emitter electrode and a feedback electrode. The sensor is fabricated on a double side polished...

Over the past 10 years, it has become possible to use the ISFET device as a cellular probe. The advantages of the ISFET, as opposed to conventional microelectrodes are (i) the possibility of measuring metabolic activity (via small pH changes in the culture media); (ii) the local amplification of the signal yielding less interference and noise and (iii) the possibility to multiplex transistor ar...

The intermetallic FeSi exhibits an unusual temperature dependence in its electronic and magnetic degrees of freedom, epitomized by the cross-over from a low-temperature nonmagnetic semiconductor to a high-temperature paramagnetic metal with a Curie-Weiss-like susceptibility. Many proposals for this unconventional behavior have been advanced, yet a consensus remains elusive. Using realistic many...
