This volume explores how ionic liquids are used in different areas of biotechnology. It also provides insights on the interaction of ionic liquids with biomolecules and biomaterials. Ionic liquids have become essential players in the fields of synthesis, catalysis, extraction and electrochemistry, and their unique properties have opened a wide range of applications in biotechnology. Readers will discover diverse examples of the application of ionic liquids as solvents for biomaterials extraction and pretreatment, in enzymatic and whole cell catalysed reaction, and as activation agents for biocatalysis. Particular attention is given to the biologically functionalized ionic liquids employed in medical and pharmaceutical applications. Although ionic liquids are considered "green solvents", the contributing authors will also explore their environmental impact when applied to biotechnology. Chemical, biological and medical scientists interested in ionic liquids and biotechnology will find this work instructive and informative.
In the ten years since the first edition appeared the "renaissance"
in Free Radical Polymerization has continued and gained momentum.
Computational Modelling of Nanoparticles highlights recent advances in the power and versatility of computational modelling, experimental techniques, and how new progress has opened the door to a more detailed and comprehensive understanding of the world of nanomaterials. Nanoparticles, having dimensions of 100 nanometers or less, are increasingly being used in applications in medicine, materials and manufacturing, and energy. Spanning the smallest sub-nanometer nanoclusters to nanocrystals with diameters of 10s of nanometers, this book provides a state-of-the-art overview on how computational modelling can provide, often otherwise unobtainable, insights into nanoparticulate structure and properties. This comprehensive, single resource is ideal for researchers who want to start/improve their nanoparticle modelling efforts, learn what can be (and what cannot) achieved with computational modelling, and understand more clearly the value and details of computational modelling efforts in their area of research.
Advances in Biomembranes and Lipid Self-Assembly, Volume 28, formerly titled Advances in Planar Lipid Bilayers and Liposomes, provides a global platform for the study of cell membranes, lipid model membranes, and lipid self-assemblies, from the micro- to the nanoscale. Planar lipid bilayers are widely studied due to their ubiquity in nature. This book presents research on their application in the formulation of biomimetic model membranes, and in the design of artificial dispersion of liposomes. Moreover, the book discusses how lipids self-assemble into a wide range of other structures, including micelles and the liquid crystalline hexagonal and cubic phases. Chapters in this volume present both original research and comprehensive reviews written by world leading experts and young researchers.
The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field. The chapters "Ionic Liquid-Liquid Chromatography: A New General Purpose Separation Methodology", "Proteins in Ionic Liquids: Current Status of Experiments and Simulations", "Lewis Acidic Ionic Liquids" and "Quantum Chemical Modeling of Hydrogen Bonding in Ionic Liquids" are available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.
This book presents the fundamentals and the state of the art of the photophysics of molecular oxygen. The author examines optical transitions between the lowest-lying electronic states in molecular oxygen and how these transitions respond to perturbation, either from an organic molecule or from the plasmon field of a metal nanoparticle. We live on a planet filled with light and oxygen. The interaction between these two components forms the basis of excited state chemistry spanning the fields of synthetic organic chemistry, materials chemistry, molecular biology, and photodynamic treatment of cancer. Still, the fundamental ways in which oxygen is affected by light is an active subject of research and is continually being developed and rationalized. In this book, readers will learn that singlet oxygen, the excited state of oxygen that exhibits unique chemical reactivity, can be selectively made via direct optical excitation of oxygen in a sensitizer-free system. Readers will also discover that this approach can perturb living cells differently depending on the singlet oxygen "dose".
This textbook provides an accessible introduction to physics for undergraduate students in the life sciences, including those majoring in all branches of biology, biochemistry, and psychology and students working on pre-professional programs such as pre-medical, pre-dental, and physical therapy. The text is geared for the algebra-based physics course, often named College Physics in the United States. The order of topics studied are such that most of the problems in the text can be solved with the methods of Statics or Dynamics. That is, they require a free body diagram, the application of Newton’s Laws, and any necessary kinematics. Constructing the text with a standardized problem-solving methodology, simplifies this aspect of the course and allows students to focus on the application of physics to the study of biological systems. Along the way, students apply these techniques to find the tension in a tendon, the sedimentation rate of red blood cells in haemoglobin, the torques and forces on a bacterium employing a flagellum to propel itself through a viscous fluid, and the terminal velocity of a protein moving in a Gel Electrophoresis device. This is part one of a two-volume set; volume 2 introduces students to the conserved-quantities and applies these problem-solving techniques to topics in Thermodynamics, Electrical Circuits, Optics, and Atomic and Nuclear Physics always with continued focus on biological applications.
This book studies the dynamics of fundamental collective excitations in quantum materials, focusing on the use of state-of-the-art ultrafast broadband optical spectroscopy. Collective behaviour in solids lies at the origin of several cooperative phenomena that can lead to profound transformations, instabilities and phase transitions. Revealing the dynamics of collective excitations is a topic of pivotal importance in contemporary condensed matter physics, as it provides information on the strength and spatial distribution of interactions and correlation. The experimental framework explored in this book relies on setting a material out-of-equilibrium by an ultrashort laser pulse and monitoring the photo-induced changes in its optical properties over a broad spectral region in the visible or deep-ultraviolet. Collective excitations (e.g. plasmons, excitons, phonons...) emerge either in the frequency domain as spectral features across the probed range, or in the time domain as coherent modes triggered by the pump pulse. Mapping the temporal evolution of these collective excitations provides access to the hierarchy of low-energy phenomena occurring in the solid during its path towards thermodynamic equilibrium. This methodology is used to investigate a number of strongly interacting and correlated materials with an increasing degree of internal complexity beyond conventional band theory.
This book considers the different concepts of hydrophile-lipophile
balance (HLB) of surfactants and solid particles and the main
physicochemical properties of surfactant and solid interfaces which
are used to definite the hydrophile-lipophile balance. The book
comprehensively analyses all interfacial and bulk properties of
surfactants used for the determination of HLB (such as interfacial
tension, distribution coefficient, adsorption, surface pressure,
surfactants solubility, structure characteristics, distribution
between heteropolar phases, micellar formation, chromatographic
characteristics, phase separation in emulsions, phase inversion
temperature, formation of three phase systems).
This book provides a modern and easy-to-understand introduction to the chemical equilibria in solutions. It focuses on aqueous solutions, but also addresses non-aqueous solutions, covering acid-base, complex, precipitation and redox equilibria. The theory behind these and the resulting knowledge for experimental work build the foundations of analytical chemistry. They are also of essential importance for all solution reactions in environmental chemistry, biochemistry and geochemistry as well as pharmaceutics and medicine. Each chapter and section highlights the main aspects, providing examples in separate boxes. Questions and answers are included to facilitate understanding, while the numerous literature references allow students to easily expand their studies.
THIS VOLUME, WHICH IS DESIGNED FOR STAND-ALONE USE IN TEACHING AND
RESEARCH, FOCUSES ON QUANTUM CHEMISTRY, AN AREA OF SCIENCE THAT

TUTORIALS AND REVIEWS COVER
This thesis investigates the combustion chemistry of cyclohexane, methylcyclohexane, and ethylcyclohexane on the basis of state-of-the-art synchrotron radiation photoionization mass spectrometry experiments, quantum chemistry calculations, and extensive kinetic modeling. It explores the initial decomposition mechanism and distribution of the intermediates, proposes a novel formation mechanism of aromatics, and develops a detailed kinetic model to predict the three cycloalkanes' combustion properties under a wide range of conditions. Accordingly, the thesis provides an essential basis for studying much more complex cycloalkanes in transport fuels and has applications in engine and fuel design, as well as emission control.
Advances in Biomembranes and Lipid Self-Assembly, Volume 27, formerly titled Advances in Planar Lipid Bilayers and Liposomes, provides a global platform for a broad community of experimental and theoretical researchers studying cell membranes, lipid model membranes, and lipid self-assemblies from the micro- to the nanoscale. The assortment of chapters in this volume represents both original research and comprehensive reviews written by world leading experts and young researchers, with topics of note in this release including TiO2 Nanomaterials as Electrochemical Biosensors for Cancer, the Reconstitution of Ion Channels in Planar Lipid Bilayers: New Approaches, and Shear-Induced Lamellar/Onion Transition in Surfactant Systems.
This thesis offers a unique guide to the development and application of ultrasensitive optical microscopy based on light scattering. Divided into eight chapters, it covers an impressive range of scientific fields, from basic optical physics to molecular biology and synthetic organic chemistry. Especially the detailed information provided on how to design, build and implement an interferometric scattering microscope, as well as the descriptions of all instrumentation, hardware interfacing and image processing necessary to achieve the highest levels of performance, will be of interest to researchers now entering the field.
This book offers a comprehensive overview of thermodynamics. It is divided into four parts, the first of which equips readers with a deeper understanding of the fundamental principles of thermodynamics of equilibrium states and of their evolution. The second part applies these principles to a series of generalized situations, presenting applications that are of interest both in their own right and in terms of demonstrating how thermodynamics, as a theory of principle, relates to different fields. In turn, the third part focuses on non-equilibrium configurations and the dynamics of natural processes. It discusses both discontinuous and continuous systems, highlighting the interference among non-equilibrium processes, and the nature of stationary states and of fluctuations in isolated systems. Lastly, part four introduces the relation between physics and information theory, which constitutes a new frontier in fundamental research. The book includes step-by-step exercises, with solutions, to help readers to gain a fuller understanding of the subjects, and also features a series of appendices providing useful mathematical formulae. Reflecting the content of modern university courses on thermodynamics, it is a valuable resource for students and young scientists in the fields of physics, chemistry, and engineering.
This thesis uses a systems-level approach to study the cellular metabolism, unveiling new mechanisms and responses that were impossible to reach with traditional reductionists procedures. The results reported here have a potential application in areas like metabolic engineering and disease treatment. They could also be used in determining the accuracy of the gene essentiality of new genome-scale reconstructions. Different methods and techniques, within the contexts of Systems Biology and the field known as Complex Networks Analysis have been applied in this work to show different features of the robustness of metabolic networks. The specific issues addressed here range from pure topological aspec ts of the networks themselves to the balance of biochemical fluxes.
This book provides state-of-the-art information on how studies in applied theoretical organic chemistry are conducted. It highlights the many approaches and tools available to those interested in using computational chemistry to predict and rationalize structures and reactivity of organic molecules. Chapters not only describe theoretical techniques in detail, but also describe recent applications and offer practical advice.Authored by many of the world leaders in the field of applied theoretical chemistry, this book is perfect for both practitioners of computational chemistry and synthetic and mechanistic organic chemists curious about applying computational techniques to their research.Related Link(s)

As the title suggests, we introduce a novel differential approach
to solution thermodynamics and use it for the study of aqueous
solutions. We evaluate the quantities of higher order derivative
than the normal thermodynamic functions. We allow these higher
derivative data speak for themselves without resorting to any model
system. We thus elucidate the molecular processes in solution,
(referred to in this book "mixing scheme"), to the depth equal to,
if not deeper, than that gained by spectroscopic and other methods.
We show that there are three composition regions in aqueous
solutions of non-electrolytes, each of which has a qualitatively
distinct mixing scheme. The boundary between the adjacent regions
is associated with an anomaly in the third derivatives of G. The
loci of the anomalies in the temperature-composition field form the
line sometimes referred as "Koga line." We then take advantage of
the anomaly of a third derivative quantity of 1-propanol in the
ternary aqueous solution, 1-propanol - sample species - H2O. We use
its induced change as a probe of the effect of a sample species on
H2O. In this way, we clarified what a hydrophobe, or a hydrophile,
and in turn, an amphiphile, does to H2O. We also apply the same
methodology to ions that have been ranked by the Hofmeister series.
We show that the kosmotropes (salting out, or stabilizing agents)
are either hydrophobes or hydration centres, and that chaotropes
(salting in, or destablizing agents) are hydrophiles.
There is currently significant interest in exploring and identifying new inorganic solar energy conversion systems based on Earth-abundant non-toxic materials for future sustainable energy applications and technologies. Developments in emergent inorganic absorbers are closely tied to the ability of researchers to correlate and predict device performance from structural and optical properties. The understanding of material structure and bonding and their effect on performance are key to developing guiding principles for design and screening of inorganic photovoltaic materials. Progress toward such understanding is facilitated by state-of-the-art tools for structural and electronic characterisation of semiconductor materials and interfaces, as well as device design and performance analysis. Further insight is provided by computer modelling and simulations. This volume brings together internationally leading scientists working in areas of material design and modelling, structural and electronic characterisation, and device design and performance analysis, to explore and exchange ideas on emerging inorganic thin-film photovoltaics based on Earth abundant non-toxic materials. In this volume, the topics covered include: Indium-free CIGS analogues Bulk and surface characterisation techniques of solar absorbers Novel chalcogenides, pnictides and defect-tolerant semiconductors Materials design and bonding |
