Book excerpt: Endohedral fullerenes represent a novel family of carbon nanostructures, which are characterized by a robust fullerene cage with atoms, ions, or clusters trapped in its interior. Since the first separation of the endohedral metallofullerene La@C 82 in 1991, a large variety of endohedral structures have been isolated and their endohedral nature has been proved by experimental studies. Within the past two decades, the world of endohedral fullerenes was significantly enlarged by the clusterfullerenes and the new carbon cages including non-IPR (IPR=isolated pentagon rule) structures. Resulting from the charge transfer from the encaged species to the fullerene cage, endohedral fullerenes hold a lot of fascinating properties inaccessible by the empty fullerenes, and consequently promise potential applications in biomedicine, molecular electronics and photonics etc. The book provides a comprehensive overview of endohedral fullerenes focused on the new advances in the past decade, including its fundamentals (structures), synthesis, isolation, characterization, properties, functionalization as well as the applications, thus representing the most updated and broad review of this exciting field.

Available in PDF, EPUB and Kindle. Book excerpt: Nanocarbon chemistry and physics is a fast-developing, broad research area – the Nobel prizes in 1996 and 2010 awarded to two key discoveries in the field, and several other nanocarbon achievements of comparable importance. Owing to this rapid growth, the nanocarbon landscape fundamentally changes every few years, creating a need to survey the field on a regular basis to update the books that have become incomplete or even obsolete. As such, this book focuses on fullerenes and metallofullerenes and also on the related areas of nanotubes and graphenes. All the covered research topics provide important fundamental knowledge for the natural sciences, but also for applications in molecular electronics, superconductivity, catalysis, photovoltaics and medical diagnostics. The current nanocarbon research activities have particularly high application potential in the conversion of solar energy, future molecular memories, non-conventional materials for optoelectronics, and new treatments for civilization diseases. Offering a truly up-to-date critical survey of nanocarbon science, its concepts and highlights, it follows the concept of a handbook: it addresses key topics systematically, from historical background, methodological aspects, current important issues, and application potential, all supplied with extensive referencing. With individual chapters written by leading experts with extensive research experience, it is a comprehensive reference resource for graduate students and active researchers alike.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantum information processing (QIP), which inherently utilizes quantum mechanical phenomena to perform information processing, may outperform its classical counterpart at certain tasks. As one of the physical implementations of QIP, the electron-spin based architecture has recently attracted great interests. Endohedral fullerenes with unpaired electrons, such as N@C60, are promising candidates to embody the qubits because of their long spin decoherence time. This thesis addresses several fundamental aspects of the strategy of engineering the N@C60 molecules for applications in QIP. Chemical functionalization of N@C60 is investigated and several different derivatives of N@C60 are synthesized. These N@C60 derivatives exhibit different stability when they are exposed to ambient light in a degassed solution. The cyclopropane derivative of N@C60 shows comparable stability to pristine N@C60, whereas the pyrrolidine derivatives demonstrate much lower stability. To elucidate the effect of the functional groups on the stability, an escape mechanism of the encapsulated nitrogen atom is proposed based on DFT calculations. The escape of nitrogen is facilitated by a 6-membered ring formed in the decomposition of the pyrrolidine derivatives of N@C60. In contrast, the 4-membered ring formed in the cyclopropane derivative of N@C60 prohibits such an escape through the addends. Two N@C6o-porphyrin dyads are synthesized. The dyad with free base porphyrin exhibits typical zero-field splitting (ZFS) features due to functionalization in the solid-state electron spin resonance (ESR) spectrum. However, the nitrogen ESR signal in the second dyad of N@C60 and copper porphyrin is completely suppressed at a wide range of sample concentrations. The dipolar coupling between the copper spin and the nitrogen spins is calculated to be 27.0 MHz. To prove the presence of the encapsulated nitrogen atom in the second dyad, demetallation of the copper porphyrin moiety is carried out. The recovery of approximately 82% of the signal intensity confirms that the dipolar coupling suppresses the ESR signal ofN@C6o. To prepare ordered structure ofN@C6o, the nematic matrix MBBA is employed to align the pyrrolidine derivatives of N@C60. Orientations of these derivatives are investigated through simulation of their ESR spectra. The derivatives with a -CH3 or phenyl group derived straightforward from the N-substituent of the pyrrolidine ring are preferentially oriented based on their powder-like ESR spectra in the MBBA matrix. An angle of about 45° is also found between the directors of fullerene derivatives and MBBA. In contrast, the derivatives with a -CH2 group inserted between the phenyl group and the pyrrolidine ring are nearly randomly distributed in MBBA. These results illustrate the applicability of liquid crystal as a matrix to align N@C60 derivatives for QIP applications.

Download or read book Encyclopedia of Astrobiology written by Muriel Gargaud and published by Springer Nature. This book was released on 2023-07-27 with total page 3376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Now in its third edition the Encyclopedia of Astrobiology serves as the key to a common understanding in the extremely interdisciplinary community of astrobiologists. Each new or experienced researcher and graduate student in adjacent fields of astrobiology will appreciate this reference work in the quest to understand the big picture. The carefully selected group of active researchers contributing to this work are aiming to give a comprehensive international perspective on and to accelerate the interdisciplinary advance of astrobiology. The interdisciplinary field of astrobiology constitutes a joint arena where provocative discoveries are coalescing concerning, e.g. the prevalence of exoplanets, the diversity and hardiness of life, and its chances for emergence. Biologists, astrophysicists, (bio)-chemists, geoscientists and space scientists share this exciting mission of revealing the origin and commonality of life in the Universe. With its overview articles and its definitions the Encyclopedia of Astrobiology not only provides a common language and understanding for the members of the different disciplines but also serves for educating a new generation of young astrobiologists who are no longer separated by the jargon of individual scientific disciplines. This new edition offers ~170 new entries. More than half of the existing entries were updated, expanded or supplemented with figures supporting the understanding of the text. Especially in the fields of astrochemistry and terrestrial extremophiles but also in exoplanets and space sciences in general there is a huge body of new results that have been taken into account in this new edition. Because the entries in the Encyclopedia are in alphabetical order without regard for scientific field, this edition includes a section “Astrobiology by Discipline” which lists the entries by scientific field and subfield. This should be particularly helpful to those enquiring about astrobiology, as it illustrates the broad and detailed nature of the field.

This book was released on 2013-03-09 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preface by Sir Harold W. Kroto, FRS Although the discovery of C60 is now almost 15 years old and the extraction occurred 60 nearly ten years ago it is amazing that the range of spin-off research still seems to expand without limits. The birth of the Fullerenes has spawned fascinating research programmes in almost every area of chemistry and physics and this monograph explores a particularly interesting and important area - the behaviour of these pure carbon cages in the presence of high-energy radiation. The C molecules must also be in the space 60 between the stars (albeit in quantities too small to detect at this time) as the conditions in the atmospheres of some carbon stars appear to be almost identical to the plasmas generated in the Kratschmer-Huffman system for making C60. The conditions in space 60 are very varied as it is pervaded by a plethora of high-energy particles (photons, cosmic rays, etc.) and the chapters in this book discuss, among other things, the response of C60 and various derivatives to probing by a range of high-energy particles. Various fullerenes and fullerene salts have been examined by positron annihilation techniques, revealing details of their electronic and structural properties as well as phase transition behaviour. Muons have been implanted to enable mSR techniques to probe with high sensitivity the endohedral electronic structures of fullerenes including those in superconducting systems. Mossbauer spectroscopy can give valuable information about the interactions in certain types of organometallic complexes and in particular it can reveal the degree of charge transfer in endohedral species. Nuclear irradiation/radiochemical analytical techniques have been applied resulting in information ranging widely from the stability of the fullerene cage containing endohedral metal atoms in various oxidation states to pharmaceutical studies of the distribution of fullerenes in the internal organs of animals. Time resolved pulsed radio lysis provides information at high sensitivity enabling micromolar concentrations to be probed e.g. C60 in water in which it is almost insoluble! Redox and rate constant measurements have given useful information on photolytically generated radical ion pairs involving a variety of fullerenes. Interesting accounts of observations involving the production of rare gas endohedral species by nuclear recoil have revealed information about the recoil mechanism. From the first moment of its discovery the unique cage structure of C60 initiated thoughts about the interesting possibility of encapsulation of atoms and molecules. One possibility that immediately suggested itself was the isolation of chemically toxic radionuclides by encapsulation in the (supposedly chemically innocuous) cage for pharmaceutical purposes. The possibility of creating cages carrying a radioactive atom inside the cage and moieties outside with molecular recognition capabilities is a most exciting prospect and discussion is included of some important first steps aimed at achieving this fascinating breakthrough. Another problem dealt with in this monograph is the effect of elemental impurities which has, as our studies progress, become more and more a matter of concern and interest. Impurities can have important effects on the observed physical and chemical behaviour of fullerenes, especially when very sensitive probe techniques are applied. This valuable book reviews some detailed studies of fundamental properties of fullerenes, which are leading to a deeper understanding of their behaviour in the presence of high energy radiation. The information obtained already and that which will be garnered in future studies of the kind described here is an absolutely necessary prerequisite for success in applications.
