This thesis addresses the problem of improving the alignment of carbon nanotubes (CNTs) in transistor applications, taking a unique approach using iptycenes acting as molecular tweezers in combination with a liquid crystal solvent. As part of a project to test the effectiveness of a multi-step method, the so-called Alignment Relay Technique (ART), this work contributed evidence for the selectivity and stability of ART, as well as providing the first proof-of-concept that ART can be used to create CNT field-effect transistors (FETs). The thesis effectively explains and illustrates the chemical synthesis of the tweezers, the concept and actualization of the technique, the various factors observed to influence deposition and selectivity, along with material fabrication using both photolithography and electron beam lithography. This research advances knowledge of transistors and expands the applications of small organic molecules in the field of materials science. Particular highlights of this thesis include: an extensive review of ART, its advantages, and limitations; development of new material chemistry methods for the optimization of semiconducting CNT selectivity; and a comprehensive exploration of fabrication and characterization of CNTFETs for future applications.
This new text book by Urs Birchler and Monika Butler is an introduction to the study of how information affects economic relations. The authors provide a narrative treatment of the more formal concepts of Information Economics, using easy to understand and lively illustrations from film and literature and nutshell examples. The book first covers the economics of information in a 'man versus nature' context, explaining basic concepts like rational updating or the value of information. Then in a 'man versus man' setting, Birchler and Butler describe strategic issues in the use of information: the make-buy-or-copy decision, the working and failure of markets and the important role of outguessing each other in a macroeconomic context. It closes with a 'man versus himself' perspective, focusing on information management within the individual. This book also comes with a supporting website (www.alicebob.info), maintained by the authors.
Geofluids: Developments in Microthermometry, Spectroscopy, Thermodynamics, and Stable Isotopes is the definitive source on paleofluids and the migration of hydrocarbons in sedimentary basins—ideal for researchers in oil and gas exploration. There's been a rapid development of new non-destructive analytical methods and interdisciplinary research that makes it difficult to find a single source of content on the subject of geofluids. Geoscience researchers commonly use multiple tools to interpret geologic problems, particularly if the problems involve fluid-rock interaction. This book perfectly combines the techniques of fluid inclusion microthermometry, stable isotope analyses, and various types of spectroscopy, including Raman analysis, to contribute to a thorough approach to research. Through a practical and intuitive step-by-step approach, the authors explain sample preparation, measurements, and the interpretation and analysis of data related to thermodynamics and mineral-fluid equilibria. - Features working examples in each chapter with step-by-step explanations and calculations - Broad range of case studies aid the analytical and experimental data - Includes appendices with equations of state, stable isotope fractionation equations, and Raman identification tables that aid in identification of fluid inclusion minerals - Authored by a team of expert scientists who have more than 60 years of related experience in the field and classroom combined
El hombre fue un guerrero desde la cabeza hasta los pies con su alma tan pura. No todos los humanos son capaces de enfrentarse a muchas criaturas místicas que son malignas e inmortales para intentar combatirlas en una lucha sobre la magia y el poder. Había tantos misterios aún por descubrir y no sería fácil descubrir cada uno de esos misterios. Había demasiada incertidumbre en todo. Esta aventura albergaba mucho más que tan sólo criaturas místicas celtas sino que también alberga los sentimientos de la traición, del temor y de la amistad. Emociones fuertes vivirán los personajes de esta historia. Cosas asombrosas e inesperadas suceden en cual tan solo la magia que alberga en ello tiene el uso de la razón cual recae ante cosas jamás antes vistas. Desafíos prácticamente imposibles de superar y criaturas místicas malignas de una peligrosidad mucho superior a las anteriores. Cada vez se vuelve más difícil avanzar por esa temible travesía que el hombre y el Darrig Lejano intentan atravesar.
