Book Description
Innovative Development in Micromanufacturing Processes details cutting edge technologies in micromanufacturing processes, an industry which has undergone a technological transformation in the past decade. Enabling engineers to create high performance, low cost, and long-lasting products, this book is an essential companion to all those working in micro and nano engineering. As products continue to get smaller and smaller, the field of micromanufacturing has gained an international audience. This book looks at both approaches of micromanufacturing: top-down and bottom-up. The top-down approach includes subtractive micromanufacturing processes such as microturning, micromilling, microdrilling, laser beam micromachining, and magnetic abrasive finishing. The bottom-up approach involves additive manufacturing processes such as micro-forming, micro deep drawing, microforging, microextrusion, and microwelding. Additionally, microjoining and microhybrid manufacturing processes are discussed in detail. The book also aids engineers and students in solving common manufacturing issues such as choice of materials and testing. The book will be of interest to those working in micro and nano engineering and machining, as well as students in manufacturing engineering, materials science, and more.

Book Description
Digital manufacturing constitutes a real industrial revolution that is transforming the production processes from the early stages of research and development to mass production and marketing. The biggest difference in comparison with old fabrication methods is the possibility to perform changes in the pattern design just by using mouse clicks instead of modifying an already fabricated prototype, which results in faster, cheaper and more efficient fabrication processes. For example, new technologies enabling the production of printed electronic devices on flexible substrates and compatible with roll-to-roll processing methods would result in cheaper fabrication costs than the traditional batch processing of silicon wafers. Such fabrication methods comprise a series of processing steps which are applied to the substrates while they are moving on rolls in the fabrication line. Therefore, it is desired that the new technologies can work at high speeds allowing at the same time the production of miniaturized features. Lasers are a versatile tool that can meet the demands of flexibility, speed, resolution and compatibility with roll-to-roll processing of digital manufacturing. The main advantages of laser radiation rely in its unique properties: high directionality, coherence and monochromaticity. The combination of such properties allows generating high intensities that can be focused into extremely small volumes, which makes lasers an ideal tool for the processing of materials at the micro- and nano-scale, not only as a subtractive but also as an additive technique. Laser ablation is the best known subtractive technique and it consists in the irradiation of a material with a focused laser beam. In the case of working with transparent materials, surface ablation constitutes a serious challenge since it is necessary to develop new strategies that allow controlling the position where the energy is delivered to ensure that ablation really occurs in the surface without modifying the bulk material. On the other hand, lasers can also be used as additive tools. For example, laser-induced forward transfer (LIFT) allows the transfer of materials in both solid and liquid state with high spatial resolution. In spite of the extensive amount of research on LIFT, some challenges still remain. For instance, the understanding of the particular printing dynamics encountered during the high speed printing of liquids, or the problem of printing uniform, continuous and stable lines with high spatial resolution. The objective of this thesis is to propose and implement feasible solutions to some of the challenges that are associated with both the subtractive and additive laser based techniques presented above. On one side, we study the laser ablation of transparent polymers using femtosecond laser pulses with the aim of achieving spatial resolutions that overcome the diffraction limit, and at the same time solving the problem of the required precise focusing of the laser beam on the materials surface. On the other side, we study the LIFT transfer dynamics during the high speed printing of liquids, and we propose alternative printing strategies to solve the inherent quality defects usually encountered during the formation of printed lines. Finally, two different approaches that are a combination of both subtractive and additive techniques are presented; we implement LIFT for the fabrication of liquid microlenses used for the surface nanopatterning of materials, and on the other side, we create fluidic guides by laser ablation for the printing of high quality continuous lines.

Book Description
This is the first book providing overview of magnetism in curved geometries, highlighting numerous peculiarities emerging from geometrically curved magnetic objects such as curved wires, shells, as well as complex three-dimensional structures. Extending planar two-dimensional structures into the three-dimensional space has become a general trend in multiple disciplines across electronics, photonics, plasmonics and magnetics. This approach provides the means to modify conventional and even launch novel functionalities by tailoring the local curvature of an object. The book covers the theory of curvilinear micromagnetism as well as experimental studies of geometrically curved magnets including both fabrication and characterization. With its coverage of fundamental aspects, together with exploration of numerous applications across magnonics, bio-engineering, soft robotics and shapeable magnetoelectronics, this edited collection is ideal for all scientists in academia and industry seeking an overview and wishing to keep abreast of advances in the novel field of curvilinear micromagnetism. It provides easy but comprehensive access to the field for newcomers, and can be used for graduate-level courses on this subject.

Book Description
Femtosecond laser-direct writing (FS-LDW) can functionalize the surface of diverse device components, including cell culture plates and medical implants. Since FS-LDW is in essence a non-contact fabrication method, it allows the surface patterning and micro-/nano-machining of material with minimal mechanical/thermal deformation. Hence, micro-/nanofabrication and material processing by femtosecond laser has attracted intense interest. Ultrafast laser ablation using far-field optics in a tight focusing configuration offers substantial advantages for the direct, maskless and arbitrary patterning of various materials and curved surfaces, while maintaining high feature resolution. Patterned surfaces with nanoscale craters or ablated pattern on electrospinning fibrous scaffolds can control and direct the cell migration. Control of topographical features in the cellular microenvironment can be achieved by combining FS-LDW with new materials. Direct laser writing by multi-photon polymerization is a nonlinear optical technique that allows the fabrication of 3D structures with resolution beyond the diffraction limit (~100nm). Incorporation of self-assembled block-copolymer nanomaterials into such structure fabricated by two-photon polymerization and, produced mesoscale structures endowed with guided nanoscale patterns (~10nm). This new capability can be used in many applications, including advanced optical metamaterials as well as for efficient photovoltaic energy conversion. In contrast, using low numerical aperture objective lens, fast fibrous structure (high aspect ratio) fabrication is possible. Well-organized fibrous structure can be used for patient-/disease-specific drug testing platform. Femtosecond laser direct writing is promising technique that can induce surface (e.g., via ablation) or volumetric patterning in a serial fashion (multi-photon polymerization). We applied these techniques to design and control multi-functional platform fabrication. As a result, FS-LDW fabricated structures exhibit higher resolution fabrication, and efficient functionality (e.g., in controlling the migration on 2D and 3D structure / tuning of mechanical stiffness of structure / directed self-assembly of block copolymer / enhancement of fluidic mixing.
