The Doomsday Vault (Everwhen School of Time Travel (and Other Odd Sciences))
by Thomas WheelerFrom the screenwriter of Academy Award–nominated Puss in Boots and Puss in Boots: The Last Wish comes an inventive middle grade adventure about an interdimensional school for time travelers perfect for fans of the Spy School and Mr. Lemoncello&’s Library series.When Bertie Wells accidentally creates a black hole in his bedroom in the year 1878, the last thing he expects is for a grown-up to step out. Darla Marconi comes with an offer: Bertie is invited to attend the EverWhen School of Time Travel and Other Odd Sciences. Not exactly thrilled at the idea, but not exactly having anything better to do, Bertie agrees. And that was only the first weird thing to happen to him that day. Thankfully, he's not alone—144 years in the future, math whiz Zoe Fuentes just accepted the same invitation, and 550 years in the past, Amelia da Vinci (yes, that da Vinci) has also decided to attend. Transported to 2024 for their first semester of school, these three must team up and work together in order to survive the year, including weathering a time paradox, solving the case of a disappearing dean, and uncovering the truth behind a shady intergalactic secret society. At least time is on their side!

Doping in Conjugated Polymers (Polymer Science and Plastics Engineering)
by Pradip KarAn A-to-Z of doping including its definition, its importance, methods of measurement, advantages and disadvantages, properties and characteristics—and role in conjugated polymers The versatility of polymer materials is expanding because of the introduction of electro-active behavior into the characteristics of some of them. The most exciting development in this area is related to the discovery of intrinsically conductive polymers or conjugated polymers, which include such examples as polyacetylene, polyaniline, polypyrrole, and polythiophene as well as their derivatives. "Synmet" or "synthetic metal" conjugated polymers, with their metallic characteristics, including conductivity, are of special interest to researchers. An area of limitless potential and application, conjugated polymers have sparked enormous interest, beginning in 2000 when the Nobel Prize for the discovery and development of electrically conducting conjugated polymers was awarded to three scientists: Alan J. Heeger, Alan G. MacDiarmid, and Hideki Shirakawa. Conjugated polymers have a combination of properties—both metallic (conductivity) and polymeric; doping gives the conjugated polymer's semiconducting a wide range of conductivity, from insulating to low conducting. The doping process is a tested effective method for producing conducting polymers as semiconducting material, providing a substitute for inorganic semiconductors. Doping in Conjugated Polymers is the first book dedicated to the subject and offers a comprehensive A-to-Z overview. It details doping interaction, dopant types, doping techniques, and the influence of the dopant on applications. It explains how the performance of doped conjugated polymers is greatly influenced by the nature of the dopants and their level of distribution within the polymer, and shows how the electrochemical, mechanical, and optical properties of the doped conjugated polymers can be tailored by controlling the size and mobility of the dopants counter ions. The book also examines doping at the nanoscale, in particular, with carbon nanotubes. Readership The book will interest a broad range of researchers including chemists, electrochemists, biochemists, experimental and theoretical physicists, electronic and electrical engineers, polymer and materials scientists. It can also be used in both graduate and upper-level undergraduate courses on conjugated polymers and polymer technology.
Doping of Carbon Nanotubes
by Sergey Bulyarskiy Alexandr SaurovThis book addresses the control of electronic properties of carbon nanotubes. It presents thermodynamic calculations of the formation of impurities and defects in the interaction of nanotubes with hydrogen, oxygen, nitrogen and boron, based on theoretical models of the formation of defects in carbon nanotubes. It is shown that doping and adsorption lead to changes in the electronic structure of the tubes as well as to the appearance of impurity states in the HOMO-LUMO gap. The book presents examples of specific calculations for doping of carbon nanotubes with oxygen, hydrogen, nitrogen and boron, together with numerous experimental results and a comparison with the author's thermodynamic calculations. Possible directions of the technological processes of optimization are pointed out, as well as the perspectives of p-n-transition creation with the help of carbon nanotube arrays. The results presented were derived from the physics of the processes and a theoretical model of the technological processes. Though a wealth of empirical information on doping nanotubes has been accumulated in the scientific literature, what is lacking is a theoretical model for their analysis. As such, the book develops a thermodynamic model of the self-organization of structural elements in multicomponent systems - including carbon nanotubes, clusters and precipitates in condensed matter - and subsequently adapts it to the doping of carbon nanotubes. This approach allows readers to gain a far deeper understanding of the processes of doping carbon nanotubes.

The Dortmund Lumbar Load Atlas: A Contribution to Objectifying Lumbar Load and Load-Bearing Capacity for an Ergonomic Work Design of Manual Materials Handling
by Matthias JägerThis handbook supports the identification of inappropriate work design in manual materials handling and thus the prevention of overloading the body and of the development of health disorders. The approach at hand, The Dortmund Lumbar Load Atlas, is focussed exclusively on biomechanical aspects of loading, overload criteria and signs of overloading in the form of verifiable low-back diseases due its strikingly frequently affectedness. Manual materials handling is understood to be the holding, lifting or lowering, pulling or pushing as well as carrying of load objects and thus the application of forces mostly with one or both hands on the item handled. Due to the biomechanical similarity, special handling tasks are also addressed, such as shoveling bulk material, transporting goods via wheelbarrow and moving people manually in the care sector. The book aims to promote interest in biomechanical approaches and provides information to all persons involved in the design, evaluation and redesign of manual materials handling, e.g. ergonomists, occupational physicians, orthopaedists, employers or researchers, lecturers and students. This handbook enables analysis of manual materials handlings regarding potential lumbar overload and contains the following:a comprehensive collection of data on lumbar load in typical manual materials handling activities—a load register on interbranch activities,synopses of previously analysed biomechanically challenging occupational activities—a load register on branch-specific activities,explanations of the methodological approach to predicting moments and forces as well as their components in relation to the lumbar spine via biomechanical modelling andcriteria for the evaluation of load data with regard to potential lumbar overloading during single operations, working shifts and the entire occupational life. The new recommendations on maximum daily exposure for lifelong work for both men and women are bridging the former gap of biomechanically justified action frequency limits and now offer the possibility of a completely biomechanical path for risk assessment of manual materials handling. The book provides hence a serious contribution to the objectification of lumbar load and load-bearing capacity aiming at an ergonomic work design of manual materials handling for short- as well as long-term exposures.

Dot-Com Design: The Rise of a Usable, Social, Commercial Web (Critical Cultural Communication #15)
by Megan Sapnar AnkersonFrom dial-up to wi-fi, an engaging cultural history of the commercial web industryIn the 1990s, the World Wide Web helped transform the Internet from the domain of computer scientists to a playground for mass audiences. As URLs leapt off computer screens and onto cereal boxes, billboards, and film trailers, the web changed the way many Americans experienced media, socialized, and interacted with brands. Businesses rushed online to set up corporate “home pages” and as a result, a new cultural industry was born: web design. For today’s internet users who are more familiar sharing social media posts than collecting hotlists of cool sites, the early web may seem primitive, clunky, and graphically inferior. After the dot-com bubble burst in 2000, this pre-crash era was dubbed “Web 1.0,” a retronym meant to distinguish the early web from the social, user-centered, and participatory values that were embodied in the internet industry’s resurgence as “Web 2.0” in the 21st century. Tracking shifts in the rules of “good web design,” Ankerson reimagines speculation and design as a series of contests and collaborations to conceive the boundaries of a new digitally networked future. What was it like to go online and “surf the Web” in the 1990s? How and why did the look and feel of the web change over time? How do new design paradigms like user-experience design (UX) gain traction? Bringing together media studies, internet studies, and design theory, Dot-com Design traces the shifts in, and struggles over, the web’s production, aesthetics, and design to provide a comprehensive look at the evolution of the web industry and into the vast internet we browse today.

Double-Gyroid-Structured Functional Materials: Synthesis and Applications
by Maik Rudolf SchererThe development of new high-tech applications and devices has created a seemingly insatiable demand for novel functional materials with enhanced and tailored properties. Such materials can be achieved by three-dimensional structuring on the nanoscale, giving rise to a significant enhancement of particular functional characteristics which stems from the ability to access both surface/interface and bulk properties. The highly ordered, bicontinuous double-gyroid morphology is a fascinating and particularly suitable 3D nanostructure for this purpose due to its highly accessible surface area, connectivity, narrow pore diameter distribution and superb structural stability. The presented study encompasses a wide range of modern nanotechnology techniques in a highly versatile bottom-up nanopatterning strategy that splits the fabrication process into two successive steps: the preparation of mesoporous double-gyroid templates utilizing diblock copolymer self-assembly, and their replication with a functional material employing electrochemical deposition and atomic layer deposition. The double-gyroid structured materials discussed include metals, metal oxides, and conjugated polymers, which are applied and characterized in high-performance devices, such as electrochromic displays, supercapacitors, chemical sensors and photovoltaics. This publication addresses a wide range of readers, from researchers and specialists who are professionally active in the field, to more general readers interested in chemistry, nanoscience and physics.
