The pulsed laser ablation in liquids (PLAL) is a rapidly emerging technique in material science for fabricating metal and metal-oxide nanoparticles. The advantage of this method over the conventional chemical methods is the lower cost, high purity and absence of defects in the formed nanoparticles (NPs). Systems of poly (n-vinylcarbazole) doped with silver nanoparticles (AgNPs) that ablated by nanosecond laser at different laser parameters such as, time of irradiation, source power and photon energy (wavelength) were prepared and studied. Structural, optical, morphological and thermal properties have been investigated using X-Ray Diffraction (XRD), Fourier Transform Infrared (FT-IR), Ultra Violet - Visible Spectra (UV-Vis), Photoluminescence (PL), Scanning Electron Microscope (SEM), Transmission Electron microscope (TEM) and Thermogravimetric Analysis (TGA).

Synthesis of One Dimensional Carbon Nanostructures

Since the discovery of carbon nanotubes by Sumio Iijima, an intensive research on carbon materials has been carried out. Carbon nanotubes and carbon nanofibers have drawn much attention due to their electronic and mechanical properties. However, because of low production capacity and high production costs at present, their applications cannot be extended until large-scale production is realized. Among the many synthetic methods, chemical vapor deposition method has advantages of high yield, high selectivity and low cost over traditional physical ones such as laser ablation and arc-discharge. High yield synthesis of one dimensional carbon nanostructures is essential for applications. In this book, an economical and environmental friendly route for the scalable production of CNTs and CNFs on easy soluble support has been discussed. The use of synthesized carbon nanotubes as catalyst support for oxidation of alcohols by Schiff base complexes and also as hydrogen storage materials is discussed in detail.

AV nodal reentrant tachycardia

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. AV nodal reentrant tachycardia (AVNRT), or atrioventricular nodal reentrant tachycardia, is a type of tachycardia (fast rhythm) of the heart. It is a type of supraventricular tachycardia (SVT), meaning that it originates from a location within the heart above the bundle of His. AV nodal reentrant tachycardia is the most common regular supraventricular tachycardia. It is more common in women than men (approximately 75% of cases occurring in females). The main symptom is palpitations. Treatment may be with specific physical maneuvers, medication, or rarely DC cardioversion. Frequent attacks may require radiofrequency ablation, in which the abnormally conducting tissue in the heart is destroyed. AVNRT occurs when a reentry circuit forms within or just next to the atrioventricular node. The circuit usually involves two anatomical pathways: the fast pathway and the slow pathway, which are both in the right atrium. The slow pathway (which is usually targeted for ablation) is located inferiorly and slightly posterior to the AV node, often following the anterior margin of the coronary sinus.

This dissertation, through a systematic investigation of the behavior of the gas-phase dynamics ofnanoparticles generated by laser ablation of solid target materials in background gasesand a study of the physical processes involved in gas-phase nanoparticle processing, explores the combination of laser and aerosol processes as a novel approach to make thinfilm materials with a level of microscopic organization similar to that found in nature.The integrated laser-aerosol method is very flexible and can be used in thesynthesis of a variety of materials. In this study it is applied to the deposition ofnanocomposite thin films comprising tetrahedral amorphous carbon (ta-C) withembedded metal nanoparticles. The controlled incorporation of metal nanoparticlesenables the modulation of the electrical conductivity of ta-C over four orders ofmagnitude without significantly or adversely affecting its mechanical properties.

After decades of development, laser ablation has become an important technique for a large number of applications such as thin film deposition, nanoparticle synthesis, micromachining, chemical analysis, etc. Experimental and theoretical studies have been conducted to understand the physical mechanisms of the laser ablation processes and their dependence on the laser wavelength, pulse duration, ambient gas and target material. The present work describes and investigates the relative importance of the physical mechanisms influencing the characteristics of aluminum laser-induced plasmas. The general scope of this research encompasses a thorough study of the interplay between the plasma plume dynamics and the ambient gas in which they expand. This is achieved by imaging and analyzing the temporal and spatial evolution the plume in terms of spectral intensity, electron density and excitation temperature within various environments, extending from vacuum to atmospheric pressure (760 Torr), in an inert gas like argon and heluim, as well as in a chemically active gas like nitrogen.

ggf. zzgl. Versand

This book is a comprehensive source of the fundamentals, process parameters, instrumental components and applications of laser-induced breakdown spectroscopy (LIBS). The effect of multiple pulses on material ablation, plasma dynamics and plasma emission is presented. A heuristic plasma modeling allows to simulate complex experimental plasma spectra. These methods and findings form the basis for a variety of applications to perform quantitative multi-element analysis with LIBS. These application potentials of LIBS have really boosted in the last years ranging from bulk analysis of metallic alloys and non-conducting materials, via spatially resolved analysis and depth profiling covering measuring objects in all physical states: gaseous, liquid and solid. Dedicated chapters present LIBS investigations for these tasks with special emphasis on the methodical and instrumental concepts as well as the optimization strategies for a quantitative analysis. Requirements, concepts, design and characteristic features of LIBS instruments are described covering laboratory systems, inspections systems for in-line process control, mobile systems and remote systems. State-of-the-art industrial applications of LIBS systems are presented demonstrating the benefits of inline process control for improved process guiding and quality assurance purposes.
