Laser ablation in liquid is becoming an important technique for the generation of nanoparticles (NPs). Until now only pulsed lasers have been used; this is a pioneer work, using high-power, high-brightness continuous-wave (CW) fibre laser ablation in liquid, for the generation of NPs. A mechanism is proposed based on experimental observations, including high-speed imaging and emission spectroscopic analysis of the ablated plume. Three different target materials (Titanium, Nickel and Alpha-aluminium-oxide), submerged in either water or sodium dodecyl sulphate (SDS) solution at various concentrations were used. The characterisation of the generated metal-oxide NPs, in terms of size, size-distribution, shape, chemical composition and phase structure was carried out by UV-Vis photo-spectroscopy, transmission electron microscopy (TEM), high-resolution TEM with energy-dispersive X-rays spectroscopy and X-ray diffraction. This study paves a route towards a new application of CW fibre lasers. The book is useful to engineering students, professional engineers, researchers, academicians and scientists in materials, NPs characterisation, mechanical, laser processing and related disciplines.

Ferromagnetic shape-memory (FSM) compounds are actively studied materials due to their large shape changes in an external magnetic field. This makes it possible to realize novel actuators and sensors. For the fabrication of micromechanical components and even microscopic machines, the material should be in thin-film form, and pulsed laser deposition (PLD) is an effective technique to reach this goal. In this thesis, FSM Ni-Mn-Ga films with a thickness of a few hundred nanometers were deposited on different substrates and methods were developed to release the film from its substrate. For efficient ablation, the intensity distribution of the laser beam on the target should be smooth with steep edges. In this work, such a distribution was realized with the help of diffractive optics. Diffractive optics was also applied to directly produce almost propagation-invariant laser beams, so-called Bessel-Gauss beams in laser resonators. Furthermore, Bessel-like laser beams were created as a result of self-focusing in a certain liquid crystal. Such diffraction-free laser beams can be used in precise laser ablation and accurate patterning of small structures in thin films.

This book is the second volume in the series 'Contact Angle, Wettability and Adhesion. ' The premier volume was published in 2013. Even a cursory glance at the literature show that in recent years the interest in understanding and controlling wetting behavior has grown exponentially. Currently, there is tremendous research activity in rendering surfaces superhydrophobic, superhydrophilic, superoleophobic, superoleophilic, omniphobic and omniphilic because of their applications in many technologically important fields. Also the durability or robustness of materials with such super' characteristics is extremely significant, as well as the utilization of 'green' (biobased) materials to obtain such surfaces. This book containing 19 articles reflects more recent developments in certain areas covered in its predecessor volume as well as it includes some topics which were not covered before. Concomitantly, this book provides a medium to keep abreast of the latest research activity and developments in the arena of contact angle, wettability and adhesion. The topics discussed include: Understanding of wetting hysteresis; fabrication of superhydrophobic materials; plasma treatment to achieve superhydrophilic surfaces; highly liquid repellent textiles; modification of paper surfaces to control liquid wetting and adhesion; Cheerios effect and its control; engineering materials with superwettability; laser ablation to create micro/nano-patterned surfaces; liquid repellent amorphous carbon nanoparticle networks; mechanical durability of liquid repellent surfaces; wetting of solid walls and spontaneous capillary flow; relationship between roughness and oleophilicity; superhydrophobic and superoleophobic green materials; computational analysis of wetting on hydrophobic surfaces: application to self-cleaning mechanisms; bubble adhesion to superhydrophilic surfaces; surface free energy of superhydrophobic materials; and role of surface free energy in pharmaceutical tablet tensile strength.

Laser-Induced Breakdown Spectroscopy
175,90 CHF *
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.
