NOVEL TECHNIQUE OF ACOUSTIC DE HAAS-VAN ALPHEN EFFECT AND APPLICATION TO LaB6

Application of microwave detection of the Shubnikov-de Haas effect in two-dimensional systems

Microwave detection of the Shubnikov-de Haas (SdH) effect as a contact-free characterization technique for different types of two-dimensional semiconductor structures is explored in the low magnetic field region. The detection technique and the data analysis are described. The character and relevance of the single-particle relaxation time that can be detected by this technique are distinguished...

Application of the airflow control by electro-hydrodynamic actuator

The technique used to control the airflow is based on the electro-hydrodynamic actuator which is also called plasma actuator. This actuator ensures the airflow control thanks to the electric wind created by the electrical corona discharge. This ionic wind is developed at the profile surface tangential to the initial free airflow so that it has a significant effect on the boundary layer flow. Th...

Uniaxial stress method for delicate crystals: Application to Shubnikov-de Haas and superconductivity studies in organic conductors

Thermally assisted photoemission effect on CeB6 and LaB6 for application as photocathodes

The thermally assisted photoemission (TAPE) effect was investigated for the hexaboride thermionic cathodes (LaB6 and CeB6). It was found that the quantum efficiency of these cathodes can be increased by raising the cathode temperature along with the thermionic emission. In addition both materials can emit a measurable photoemission current by being irradiated with a laser having a photon energy...

Effect of topical Vancomycin on consolidation of sternum surgical fracture in open-heart surgery

Introduction: The physiological process of sternum surgical fracture consolidation in patients undergoing cardiac surgery could be prolonged by the invasion of gram-positive saprophytic bacteria which perpetuates the local inflammatory process despite the standardized aseptic and antiseptic measures in cardiac surgery. In this regard, the topical application of Vancomycin can e...
