Functional Supramolecular Nanoassemblies of Π-Conjugated Molecules by Penglei Chen,Bin Wu Pdf

Π-conjugated systems of delocalized aromatic electrons along their backbones, including conjugated small molecules, oligomers, polymers, and carbonaceous materials, etc., have received considerable attention from a wide variety of scientific and technical communities. Compared to inorganic materials, the advantages of those based on π-tectons lie in their broad diversity, flexibility, and tunability with regard to structure/geometry/morphology, processability, composition, functionality, electronic/band structure, etc. In terms of sophisticated molecular engineering, these features endow them not only with excellent self-assembly properties but also with unique optical, electrical, mechanical, photophysical, photochemical, and biochemical attributes. This renders them promising scaffolds for advanced functional materials (AFMs) in numerous areas of general interest such as electronics, optics, optoelectronics, photovoltaics, magnetic and piezoelectric devices, sensors, catalysts, biomedicines, and others. With regard to the design/synthesis of novel π-tectons, the launch of diverse assembly/fabrication protocols, theoretical calculations, etc., the past several decades have witnessed tremendous advancements along this direction. Thus far, a vast array of high-performance π-tectons-based AFMs have been initiated. To some extent, the cooperative principle of π-πstacking and other noncovalent interactions has been revealed, and the structure-property relationships have been disclosed. Despite the existing progress, this field still faces challenges, for example: (i) the need for scalable assembly/manufacture under ambient conditions—with low-cost, facile, environmentally-friendly protocols (ii) clearer correlations bridging the underlying intricate relationships of each successive step in assembly/manufacture (iii) corresponding theoretical calculations for guiding the rational design of π-tectons that elucidate the cooperative principle of π-π stacking and other noncovalent interactions, as well as the principle of structure-performance correlation (iv) stability and durability, among the most important concerns regarding their commercialization The advancements accumulated during the past decades have established a solid foundation for the further development of π-conjugated systems-based AFMs. We believe that with unrelenting efforts from both scientific and technical communities of various backgrounds, their practical applications will eventually be fulfilled. This Research Topic aims to address the above-mentioned challenges

Molecular Evolution and Protobiology by Koichiro Matsuno Pdf

In recent years, an ever-increasing amount of research has been conducted on the physico-chemical basis of the origin and evolution of life, or protobiology. Many questions are raised in this endeavor: What research methodology should be employed? What sort of dependable facts are available as a firm frame of reference upon which the physico-chemical origin of life or protolife could be examined? Is the origin due exclusively to chance events? If not, what is then responsible for the origin? What physical reality underlies the evolutionarily selective process leading to the origin? What role does variation assume and how is it generated in the course of evolution? Many research workers have pursued various avenues toward answering the stated questions. Among them, we believe Sidney W. Fox has been playing a very unique and pivotal role over the past quarter of a century, presiding over 240 man-years or more of labo ratory work. His laboratory syntheses of thermal proteins called proteinoids and proteinoid micro spheres have emphasized the prin ciple of the self-sequencing of amino acids as a key concept of protobiological synthesis. The significance of his contribution is seen in presenting the experimental evidence that the origin of life is largely due to nonrandom events. This discovery marks a new epoch in the conceptual development of studying the origin of life by focusing on the molecular processes that underlied the emergence and evolution of protobiological information.

Population Genetics, Molecular Evolution, and the Neutral Theory by Motoo Kimura Pdf

One of this century's leading evolutionary biologists, Motoo Kimura revolutionized the field with his random drift theory of molecular evolution—the neutral theory—and his groundbreaking theoretical work in population genetics. This volume collects 57 of Kimura's most important papers and covers forty years of his diverse and original contributions to our understanding of how genetic variation affects evolutionary change. Kimura's neutral theory, first presented in 1968, challenged the notion that natural selection was the sole directive force in evolution. Arguing that mutations and random drift account for variations at the level of DNA and amino acids, Kimura advanced a theory of evolutionary change that was strongly challenged at first and that eventually earned the respect and interest of evolutionary biologists throughout the world. This volume includes the seminal papers on the neutral theory, as well as many others that cover such topics as population structure, variable selection intensity, the genetics of quantitative characters, inbreeding systems, and reversibility of changes by random drift. Background essays by Naoyuki Takahata examine Kimura's work in relation to its effects and recent developments in each area.

Molecular Electronic Control Over Tunneling Charge Transfer Plasmons Modes by Shu Fen Tan Pdf

This thesis describes the controlled immobilization of molecules between two cuboidal metal nanoparticles by means of a self-assembly method to control the quantum plasmon resonances. It demonstrates that quantum-plasmonics is possible at length scales that are useful for real applications. Light can interact with certain metals and can be captured in the form of plasmons, which are collective, ultra-fast oscillations of electrons that can be manipulated at the nano-scale. Surface plasmons are considered as a promising phenomenon for potentially bridging the gap between fast-operating-speed optics and nano-scale electronics. Quantum tunneling has been predicted to occur across two closely separated plasmonic resonators at length scales (0.3 nm) that are not accessible using present-day nanofabrication techniques. Unlike top-down nanofabrication, the molecules between the closely-spaced metal nanoparticles could control the gap sizes down to sub-nanometer scales and act as the frequency controllers in the terahertz regime, providing a new control parameter in the fabrication of electrical circuits facilitated by quantum plasmon tunneling.

Molecular Beams in Physics and Chemistry by Bretislav Friedrich,Horst Schmidt-Böcking Pdf

This Open Access book gives a comprehensive account of both the history and current achievements of molecular beam research. In 1919, Otto Stern launched the revolutionary molecular beam technique. This technique made it possible to send atoms and molecules with well-defined momentum through vacuum and to measure with high accuracy the deflections they underwent when acted upon by transversal forces. These measurements revealed unforeseen quantum properties of nuclei, atoms, and molecules that became the basis for our current understanding of quantum matter. This volume shows that many key areas of modern physics and chemistry owe their beginnings to the seminal molecular beam work of Otto Stern and his school. Written by internationally recognized experts, the contributions in this volume will help experienced researchers and incoming graduate students alike to keep abreast of current developments in molecular beam research as well as to appreciate the history and evolution of this powerful method and the knowledge it reveals.

Membranes to Molecular Machines by Mathias Grote Pdf

Today's science tells us that our bodies are filled with molecular machinery that orchestrates all sorts of life processes. When we think, microscopic "channels" open and close in our brain cell membranes; when we run, tiny "motors" spin in our muscle cell membranes; and when we see, light operates "molecular switches" in our eyes and nerves. A molecular-mechanical vision of life has become commonplace in both the halls of philosophy and the offices of drug companies, where researchers are developing “proton pump inhibitors” or medicines similar to Prozac. Membranes to Molecular Machines explores just how late twentieth-century science came to think of our cells and bodies this way. This story is told through the lens of membrane research, an unwritten history at the crossroads of molecular biology, biochemistry, physiology, and the neurosciences, that directly feeds into today's synthetic biology as well as nano- and biotechnology. Mathias Grote shows how these sciences not only have made us think differently about life, they have, by reworking what membranes and proteins represent in laboratories, allowed us to manipulate life as "active matter" in new ways. Covering the science of biological membranes in the United States and Europe from the mid-1960s to the 1990s, this book connects that history to contemporary work with optogenetics, a method for stimulating individual neurons using light, and will enlighten and provoke anyone interested in the intersection of chemical research and the life sciences—from practitioner to historian to philosopher. The research described in the book and its central actor, Dieter Oesterhelt, were honored with the 2021 Albert Lasker Basic Medical Research Award for his contribution to the development of optogenetics.
