Graphene is an attractive alternative material for diverse applications in electronic devices, fuel cells, biomedical sensors, energy storage, and super-capacitors due to its exceptional thermal,electrical, optical and mechanical properties. This material can be synthesized by many effective methods such as chemical vapor deposition,and micromechanical exfoliation of graphite. This book investigates a novel and clean approach to grow graphene directly from bulk graphite by Pulsed Laser Ablation in Liquid. This technique is simple, and fast,a one-step procedure to fabricate pure and stable graphene nanoparticles by short ablation time. It results in controllable-size products, high mass production, high stability, less aggregation, and absence of chemical agents,a known disadvantages observed in other approaches for graphene production. Confirming the presence of graphene is carried out by several characterization techniques including Raman spectroscopy, UV-VISIBLE, AFM, SEM,and TEM. These techniques allow an insight into the morphological and structural properties of the produced graphene. The potential recipe for growing high quality graphene is intensively explained in this book.
This book is about the interaction of laser radiation with various surfaces at variable parameters of radiation. As a basic principle of classification we chose the energetic or intensity level of interaction of laser radiation with the surfaces. These two characteristics of laser radiation are the most important parameters defining entire spectrum of the processes occurring on the surfaces during interaction with electromagnetic waves.This is a first book containing a whole spectrum of the laser-surface interactions distinguished by the ranges of used laser intensity. It combines the surface response starting from extremely weak laser intensities (~1 W cm-2) up to the relativistic intensities (~1020 W cm-2 and higher). The book provides the basic information about lasers and acquaints the reader with both common applications of laser-surface interactions (laser-related printers, scanners, barcode readers, discs, material processing, military, holography, medicine, etc) and unusual uses of the processes on the surfaces under the action of lasers (art conservation, rangefinders and velocimeters, space and earth explorations, surface engineering and ablation, and others). The scientific applications of laser-surfaces interactions (surface optical nonlinearities, surface enhanced Raman spectroscopy, surface nanostructuring, nanoripples and clusters formation, X-ray lasers and harmonic generation from the surfaces) are discussed from the point of view of the close relations between the properties of surface and matter, which is a cornerstone of most of studies of materials.The novelty of the approach developed in Laser - Surface Interactions is related with the interconnection of scientific studies with numerous applications of the laser-surface interactions separated in different chapters by the ranges of laser intensities. We present most recent achievements in this field. The book provides valuable information for different ranges of reader's preparedness to the laser-related topics (from unprepared readers, to students, engineers and researchers, professionals and academics).
The pulsed laser ablation in liquid media (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). The technique requires the minimum amount of chemical species for synthesis compared to the conventional chemical process and provides greater flexibility in controlling the properties of NPs by suitable choice of laser parameters and liquid medium. This work discuss effect of various laser parameters, surrounding liquid and surfactants on synthesized metal oxide nanostructures. Different approaches to extend PLAL technique to multicomponent material fabrication has been discussed. These multicomponent nanocomposites exhibit modified optical properties, enhanced stability and functionalities.
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).
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.
