This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This Thesis presents the synthesis of a new family of liquid crystal (LC)-capped gold nanoparticles (AuNPs) for a rationalized miscibility and assembly in liquid crystal matrices.A new protocol based on the thiol-for-dimethylaminopyridine (DMAP) ligand exchange reaction was developed to prepare 4-5 nm AuNPs with mono and binary capping layers made of alkanethiol (CH3(CH2)mSH; m = 5, 11) and liquid crystal ligand 4'-(n-mercaptoalkoxy)biphenyl-4-carbonitriles (CBO(CH2)nSH; n = 8, 12, 16). AuNPs with a 1 : 1 CH3(CH2)5SH/CBO(CH2)12SH ratio were found to have an unprecedented miscibility in isotropic 4-n-pentyl-4'-cyanobiphenyl (5CB) and 4-n-octyl-4'-cyanobiphenyl (8CB) liquid crystals exceeding 25 wt% Au. While low NP concentrations are normally used to avoid aggregation, concentrated dispersions of these AuNPs form new structures at the LC phase transitions through coupling of the interparticle attractive forces with the LC elastic interactions. Upon cooling to TN-I...

Book excerpt: This book brings together the many concepts and discoveries in liquid crystal colloids contributed over the last twenty years and scattered across numerous articles and book chapters. It provides both a historical overview of the development of the field and a clear perspective on the future applications in photonics. The book covers all phenomena observed in liquid crystal colloids with an emphasis on experimental tools and applications of topology in condensed matter, as well as practical micro-photonics applications. It includes a number of spectacular manifestations of new topological phenomena not found or difficult to observe in other systems. Starting from the early works on nematic colloids, it explains the basics of topological defects in ordered media, charge and winding, and the elastic forces between colloidal particles in nematics. Following a detailed description of experimental methods, such as optical tweezing and particle tracking, the book eases the reader into the theoretical part, which deals with elastic deformation of nematic liquid crystals due to inclusions and surface alignment. This is discussed in the context of basic mean field Landau-de Gennes Q-tensor theory, with a brief explanation of the free-energy minimization numerical methods. There then follows an excursion into the topology of complex nematic colloidal structures, colloidal entanglement, knotting and linking. Nematic droplets, shells, handlebodies and chiral topological structures are addressed in separate chapters. The book concludes with an extensive chapter on the photonic properties of nematic dispersions, presenting the concept of integrated soft matter photonics and discussing the concepts of nematic and chiral nematic microlasers, surface-sensitive photonic devices and smectic microfibers. The text is complemented by a large bibliography, explanatory sketches and beautiful micrographs.

This book was released on 2011-09-02 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discovery of the spatial structure of the double-stranded DNA molecule is one of the greatest achievements of science. It would not be an exaggeration to say that the DNA double helix is a distinguished symbol of modern biology. Divided into three parts, DNA Liquid-Crystalline Dispersions and Nanoconstructions covers the information presently available on the condensation of various forms of DNA and describes practical applications of the peculiar properties of the liquid-crystalline particles. Part 1 describes the main methods used for condensation of linear high- and low-molecular mass DNA, including their complexes with polycations and circular DNA Part 2 compares the state and reactivity of double-stranded nucleic acid molecules fixed spatially in the liquid-crystalline as well as the same molecules under intracellular conditions Part 3 explains how the discovery of the fundamental principles underlying the formation of nucleic acid liquid-crystalline dispersion particles opens a gate for the operational use of these principles in the area of nanotechnology and biosensorics With detailed coverage of DNA liquid crystals, this book provides an understanding of the information presently available on the condensation of various forms of DNA. Double-stranded nucleic acids, spatially organized in a liquid-crystalline structure, represent an important polyfunctional tool for molecular biology and nanobiotechnology. The possibility of programmed and controlled variations in the properties of these molecules and in the characteristics of their liquid-crystalline dispersions, provides wide options for the formation of biologically active three-dimensional structures with unique, widely applicable properties.

This book was released on 2016-10-10 with total page 944 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'The overall book content is excellently coordinated to form a synchronised story, interesting to a broad scientific audience … The book summarises the present knowledge in the field, introduces fundamental concepts to the beginners, describes key measuring methods and presents several different typical demonstrative systems, some of them exhibiting an extraordinary rich spectrum of structures and superstructures. I am sure that with time the book will become an attractor to a broad audience (physicists, chemists, material scientists, engineers, etc.), ranging from students, beginners in the field to experienced researchers. To summarise, this is the book that I have been missing on my bookshelf.'Liquid Crystals TodayWhile liquid crystals are today widely known for their successful application in flat panel displays (LCDs), academic liquid crystal research is more and more targeting situations where these anisotropic fluids are put to completely different use, in varying contexts. A particularly strong focus is on colloidal liquid crystals, where particles, bubbles or drops are dispersed in a liquid crystal phase. The liquid crystal can act as a host phase, with the inclusions constituting foreign guests that disturb the local order in interesting ways, often resulting in large-scale positional arrangement and/or uniform alignment of the guests. But it may also be formed by solid particles themselves, if these are of nanoscale dimensions and of disc- or rod-shape, and if they are suspended in an isotropic liquid host at sufficient concentration.This book aims to cover both the modern research tracks, gathering pioneering researchers of the different subfields to give a concise overview of the basis as well as the prospects of their respective specialties. The scope spans from curiosity-driven fundamental scientific research to applied sciences. Over the course of the next decade, the former is likely to generate new tracks of the latter type, considering the exploratory and productive phase of this young research field.
