Liganded silver and gold quantum clusters. Towards a new class of nonlinear optical nanomaterials (SpringerBriefs in Materials)

by Rodolphe Antoine Vlasta Bonačić-Koutecký

Metallic quantum clusters belonging to intermediate size regime between two and few hundred of atoms, represent unique building blocks of new materials. Nonlinear optical (NLO) characteristics of liganded silver and gold quantum clusters reveal remarkable features which can be tuned by size, structure and composition. The two-photon absorption cross sections of liganded noble metal quantum clusters are several orders of magnitude larger than that of commercially-available dyes. Therefore, the fundamental photophysical understanding of those two-photon processes in liganded clusters with few metal atoms deserve special attention, in particularly in context of finding the mechanisms responsible for these properties. A broad range of state-of-the-art experimental methods to determine nonlinear optical properties (i.e. two-photon absorption, two-photon excited fluorescence and second harmonic generation) of quantum clusters are presented. The experimental setup and underlying physical concepts are described. Furthermore, the theoretical models and corresponding approaches are used allowing to explain the experimental observations and simultaneously offering the possibility to deduce the key factors necessary to design new classes of nanoclusters with large NLO properties. Additionally, selected studied cases of liganded silver and gold quantum clusters with focus on their NLO properties will be presented as promising candidates for applications in imaging techniques such as fluorescence microscopy or Second-Harmonic Generation microscopy.

Light Driven Micromachines

by Kenji Uchino George K. Knopf

In Light Driven Micromachines, the fundamental principles and unique characteristics of light driven material structures, simple mechanisms and integrated machines are explored. Very small light driven systems provide a number of interesting features and unique design opportunities because streams of photons deliver energy into the system and provide the control signal used to regulate the response of the micron sized device. Through innovative material design and clever component fabrication, these optically powered tiny machines can be created to perform mechanical work when exposed to varying light intensity, wavelength, phase, and/or polarization. The book begins with the scientific background necessary to understand the nature of light and how light can initiate physical movement by inducing material deformation or altering the surrounding environment to impose micro-forces on the actuating mechanisms. The impact of physical size on the performance of light driven mechanisms and machines is discussed, and the nature of light–material interactions is reviewed. These interactions enable very small objects and mechanical components to be trapped and manipulated by a focused light beam, or produce local temperature gradients that force certain materials to undergo shape transformation. Advanced phase transition gels, polymers, carbon-based films and piezoelectric ceramics that exhibit direct light-to-mechanical energy conversion are examined from the perspective of designing optically driven actuators and mechanical systems. The ability of light to create photothermal effects that drive microfluidic processes and initiate the phase transformation of temperature sensitive shape memory materials are also explored in the book. This compendium seeks to inspire the next generation of scientists and engineers by presenting the fundamental principles of this emerging interdisciplinary technology and exploring how the properties of light can be exploited for microfluidic, microrobotic, biomedical and space applications.

Light It Up: The Marine Eye for Battle in the War for Iraq

by John Pettegrew

Examines the U.S. Marines’ visual culture of combat in the Iraq War.American military power in the War on Terror has increasingly depended on the capacity to see the enemy. The act of seeing—enhanced by electronic and digital technologies—has separated shooter from target, eliminating risk of bodily harm to the remote warrior, while YouTube videos eroticize pulling the trigger and video games blur the line between simulated play and fighting.Light It Up examines the visual culture of the early twenty-first century military. Focusing on the Marine Corps, which played a critical part in the invasion and occupation of Iraq, John Pettegrew argues that U.S. military force in the Iraq War was projected through an "optics of combat." Powerful military technology developed in the Iraq and Afghanistan wars has placed war in a new posthuman era.Pettegrew’s interviews with marines, as well as his analysis of first-person shooter videogames and combat footage, lead to startling insights into the militarization of popular digital culture. An essential study for readers interested in modern warfare, policy makers, and historians of technology, war, and visual and military culture.

Light Pollution in Metropolises: Analysis, Impacts and Solutions

by Emlyn Etienne Goronczy

Light pollution (light smog, light pollution or light emissions) is a fundamental problem in metropolises with effects on flora, fauna and people. Accordingly, the first section of the book discusses the basics of light pollution and its effects on various organisms. The characteristics of light smog in the cities of Hanover, Warsaw, Boston, New York City and Toronto are then analysed and compared. But how can the problem be tackled? Existing measures for the prevention of light pollution are discussed and further novel approaches are shown by comparing the metropolises. The book is aimed primarily at practitioners in this field and helps to identify sources of emissions and identify suitable reduction measures. This book is a translation of the original German edition „Lichtverschmutzung in Metropolen“ by Emlyn Etienne Goronczy, published by Springer Fachmedien Wiesbaden GmbH in 2018. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors.

Light Propagation in Linear Optical Media

by Shekhar Guha Glen D. Gillen Katharina Gillen

Light Propagation in Linear Optical Media describes light propagation in linear media by expanding on diffraction theories beyond what is available in classic optics books. In one volume, this book combines the treatment of light propagation through various media, interfaces, and apertures using scalar and vector diffraction theories. After covering the fundamentals of light and physical optics, the authors discuss light traveling within an anisotropic crystal and present mathematical models for light propagation across planar boundaries between different media. They describe the propagation of Gaussian beams and discuss various diffraction models for the propagation of light. They also explore methods for spatially confining (trapping) cold atoms within localized light-intensity patterns. This book can be used as a technical reference by professional scientists and engineers interested in light propagation and as a supplemental text for upper-level undergraduate or graduate courses in optics.

Light Science: Physics and the Visual Arts (Undergraduate Texts In Contemporary Physics Ser.)

by Thomas D. Rossing Christopher J. Chiaverina

Intended for students in the visual arts and for others with an interest in art, but with no prior knowledge of physics, this book presents the science behind what and how we see. The approach emphasises phenomena rather than mathematical theories and the joy of discovery rather than the drudgery of derivations. The text includes numerous problems, and suggestions for simple experiments, and also considers such questions as why the sky is blue, how mirrors and prisms affect the colour of light, how compact disks work, and what visual illusions can tell us about the nature of perception. It goes on to discuss such topics as the optics of the eye and camera, the different sources of light, photography and holography, colour in printing and painting, as well as computer imaging and processing.
