We report direct observations of anomalous magnetic-field and temperature dependences of the Shubnikov–de Haas oscillations in the organic superconductor b9-(BEDT-TTF)2SF5CH2CF2SO3. Unlike other BEDT-TTF based organic superconductors, a nonmetallic temperature dependence of the background magnetoresistance is clearly observed. It is speculated that the nonmetallic behavior may arise from a part...

Heteroatom-doped carbon materials have been one of the most remarkable families of materials with promising applications in fuel cells, supercapacitors, and batteries. Among them, conjugated polymer (CP)-derived heteroatom-doped carbon materials exhibit remarkable electrochemical performances because the heteroatoms can be preserved at a relatively high content and keep stable under harsh worki...

Abstract Materials such as biocompatible metals, ceramics, composites, and polymers are used in the fabrication of biomedical implants which human body especially for replacement hard tissues. However, they degrade with time since subjected to different mechanical conditions long-term exposure fluids corrosion. Therefore, curb these limitations, surface properties usually coated thin metallic n...

Magnesium and magnesium alloys have great application potential in the field of orthopaedics. Compared with traditional inorganic nonmetallic materials medical polymer materials, many advantages, such as better strength, toughness, fatigue resistance, easy processing. Its mechanical properties are suitable controllable. It can meet same elastic modulus, cell compatibility, biodegradability huma...

Recent events have led to dramatic changes to the methods employed in security screening. For example, following the failed shoe bombing, it is now common for shoes to be removed and X-rayed at airport checkpoints. There is therefore an increasing focus on new technologies that can be applied to security screening, either to simplify or speed up the checking process, or to provide additional fu...

STUDY DESIGN A variety of interbody implants were imaged by computed tomography and plain radiography within cadaveric spines to evaluate their basic imaging characteristics. OBJECTIVES Sources of interpretation error by both computed tomography and plain radiography of interbody implants were investigated. SUMMARY OF BACKGROUND DATA Lucencies have been reported around bone dowel implants i...

Currently, the goods sorting process in industry still uses a manual method. Therefore, it is necessary to propose an automatic method using control technology. In order realize above issue, automated proposed separate plastic materials and metallic prototype of process. our study, bottle metal detector was designed TCRT5000 infrared sensor Arduino Uno-based Proximity sensor. The functions dete...
