Book Description
Examining the physical and technical foundation for recent progress with this technique, Applied Scanning Probe Methods offers a timely and comprehensive overview of SPM applications, now that industrial applications span topographic and dynamical surface studies of thin-film semiconductors, polymers, paper, ceramics, and magnetic and biological materials. First it lays the theoretical background of static and dynamic force microscopies, including sensor technology and tip characterization, contributions detail applications such as macro- and nanotribology, polymer surfaces, and roughness investigations. The final part on industrial research addresses special applications of scanning force nanoprobes such as atomic manipulation and surface modification, as well as single electron devices based on SPM.

Book Description
Accurate measurement at the nano-scale – nanometrology – is a critical tool for advanced nanotechnology applications, where exact quantities and engineering precision are beyond the capabilities of traditional measuring techniques and instruments. Scanning Probe Microscopy (SPM) builds up a picture of a specimen by scanning with a physical probe; unrestrained by the wavelength of light or electrons, the resolution obtainable with this technique can resolve atoms. SPM instruments include the Atomic Force Microscope (AFM) and Scanning Tunneling Microscope (STM). Despite tremendous advances in Scanning Probe Microscopy (SPM) over the last twenty years, its potential as a quantitative measurement tool have not been fully realized, due to challenges such as the complexity of tip/sample interaction. In this book, Petr Klapetek uses the latest research to unlock SPM as a toolkit for nanometrology in fields as diverse as nanotechnology, surface physics, materials engineering, thin film optics, and life sciences. Klapetek's considerable experience of Quantitive Data Processing, using software tools, enables him to not only explain the microscopy techniques, but also to demystify the analysis and interpretation of the data collected. In addition to the essential principles and theory of SPM metrology, Klapetek provides readers with a number of worked examples to demonstrate typical ways of solving problems in SPM analysis. Source data for the examples as well as most of the described open source software tools are available on a companion website. - Unlocks the use of Scanning Probe Microscopy (SPM) for nanometrology applications in engineering, physics, life science and earth science settings - Provides practical guidance regarding areas of difficulty such as tip/sample interaction and calibration – making metrology applications achievable - Gives guidance on data collection and interpretation, including the use of software-based modeling (using applications that are mostly freely available)

Book Description
The sense of touch is fundamental during the interaction between humans and their environment; in virtual reality, objects are created by computer simulations and they can be experienced through haptic devices. In this context haptic textures are fundamental for a realistic haptic perception of virtual objects. This book formalizes the specific artefacts corrupting the rendering of virtual haptic textures and offers a set of simple conditions to guide haptic researchers towards artefact-free textures. The conditions identified are also extremely valuable when designing psychophysical experiments and when analyzing the significance of the data collected. The Synthesis of Three Dimensional Haptic Textures, Geometry, Control, and Psychophysics examines the problem of rendering virtual haptic textures with force feedback devices. The author provides an introduction to the topic of haptic textures that covers the basics of the physiology of the skin, the psychophysics of roughness perception, and the engineering challenges behind haptic textures rendering. The book continues with the presentation of a novel mathematical framework that characterizes haptic devices, texturing algorithms and their ability to generate realistic haptic textures. Finally, two psychophysical experiments link the perception of roughness with the parameters of the haptic rendering algorithms. This book formalizes the specific artefacts corrupting the rendering of virtual haptic textures and offers a set of simple conditions to guide haptic researchers towards artefact-free textures. The conditions identified are also extremely valuable when designing psychophysical experiments and when analyzing the significance of the data collected.

Book Description
Active touch can be described as the control of the position and movement of tactile sensing systems to facilitate information gain. In other words, it is finding out about the world by reaching out and exploring—sensing by ‘touching’ as opposed to ‘being touched’. In this Research Topic (with cross-posting in both Behavioural Neuroscience and Neurorobotics) we welcomed articles from junior researchers on any aspect of active touch. We were especially interested in articles on the behavioral, physiological and neuronal underpinnings of active touch in a range of species (including humans) for submission to Frontiers in Behavioural Neuroscience. We also welcomed articles describing robotic systems with biomimetic or bio-inspired tactile sensing systems for publication in Frontiers in Neurorobotics.

Book Description
The topic of wettabilty is extremely important from both fundamental and applied aspects. The applications of wettability range from self-cleaning windows to micro- and nanofluidics. This book represents the cumulative wisdom of a contingent of world-class (researchers engaged in the domain of wettability. In the last few years there has been tremendous interest in the "Lotus Leaf Effect" and in understanding its mechanism and how to replicate this effect for myriad applications. The topics of superhydrophobicity, omniphobicity and superhydrophilicity are of much contemporary interest and these are covered in depth in this book.

Book Description
When young, we didn’t have cellular devices but communicated through handwritten letter. We walked miles to school, in the sun and the rain. It’s mind-boggling to think how far we’ve come technologically. “Objects in mirror are closer than they appear.” That familiar warning applies to the windshield, not the rear view mirror when it comes to technology. And in case of exponential technologies, almost everything is closer than it appears. Today’s students will be graduating in and around 2030. Over 65% of the jobs of that time have not been invented yet. What knowledge, skills and dispositions will our learners need for a successful future? How will exponential changes in technology influence them? How can they shape the future instead of being shaped by it? There is an urgent need to be aware of exponential technologies which will usher in singularity, a point in time when artificial intelligence will equal and then surpass biological intelligence. An exploratory design of medical nanotechnology and robotics is creating mechanical artificial red blood cells, called respirocytes, which will deliver 236 times more oxygen to the tissues per unit volume. One can then do an Olympic sprint in fifteen minutes without taking a breath. Earth is awash with the sun’s rays carrying 10,000 times more energy than we need but we cannot harness it. In a foreseeable future, highly efficient, lightweight, nano-engineered solar panels will be able to store solar energy in distributed nanotechnology-based fuel cells. In the field of health, we are going to have tools to reprogram biology to block diseases and delay aging. We need our future scientists and engineers to be wholesome human beings with the ability to think critically and pay heed to the moral and ethical issues of future technologies. Notwithstanding these issues, all great technological breakthroughs are absolutely necessary to alleviate poverty, disease, suffering and create abundance.
