This textbook introduces thermodynamics with a modern approach,
starting from four fundamental physical facts (the atomic nature of
matter, the indistinguishability of atoms and molecules of the same
species, the uncertainty principle, and the existence of
equilibrium states) and analyzing the behavior of complex systems
with the tools of information theory, in particular with Shannon's
measure of information (or SMI), which can be defined on any
probability distribution. SMI is defined and its properties and
time evolution are illustrated, and it is shown that the entropy is
a particular type of SMI, i.e. the SMI related to the phase-space
distribution for a macroscopic system at equilibrium. The
connection to SMI allows the reader to understand what entropy is
and why isolated systems follow the Second Law of Thermodynamics.
The Second Llaw is also formulated for other systems, not thermally
isolated and even open with respect to the transfer of particles.
All the fundamental aspects of thermodynamics are derived and
illustrated with several examples in the first part of the book.
The second part addresses important applications of thermodynamics,
covering phase transitions, mixtures and solutions (including the
Kirkwood-Buff approach and solvation thermodynamics), chemical
equilibrium, and the outstanding properties of water.This textbook
is unique in two aspects. First, thermodynamics is introduced with
a novel approach, based on information theory applied to
macroscopic systems at equilibrium. It is shown that entropy is a
particular case of Shannon's measure of information (SMI), and the
properties and time evolution of the SMI are used to explain the
Second Law of Thermodynamics. This represents a real breakthrough,
as classical thermodynamics cannot explain entropy, nor clarify why
systems should obey the Second Law. Second, this textbook offers
the reader the possibility to get in touch with important and
advanced applications of thermodynamics, to address the topics
discussed in the second part of the book. Although they may go
beyond the content of a typical introductory course on
thermodynamics, some of them can be important in the curriculum
chosen by the student. At the same time, they are of appealing
interest to more advanced scholars.
In these lectures we summarize certain results on models in
statistical physics and quantum field theory and especially
emphasize the deep relation ship between these subjects. From a
physical point of view, we study phase transitions of realistic
systems; from a more mathematical point of view, we describe field
theoretical models defined on a euclidean space-time lattice, for
which the lattice constant serves as a cutoff. The connection
between these two approaches is obtained by identifying partition
functions for spin models with discretized functional integrals.
After an introduction to critical phenomena, we present methods
which prove the existence or nonexistence of phase transitions for
the Ising and Heisenberg models in various dimensions. As an
example of a solvable system we discuss the two-dimensional Ising
model. Topological excitations determine sectors of field
theoretical models. In order to illustrate this, we first discuss
soliton solutions of completely integrable classical models.
Afterwards we dis cuss sectors for the external field problem and
for the Schwinger model. Then we put gauge models on a lattice,
give a survey of some rigorous results and discuss the phase
structure of some lattice gauge models. Since great interest has
recently been shown in string models, we give a short introduction
to both the classical mechanics of strings and the bosonic and
fermionic models. The formulation of the continuum limit for
lattice systems leads to a discussion of the renormalization group,
which we apply to various models."
Thermodynamics is fundamental to university and college curricula
in chemistry, physics, engineering and many life sciences around
the world. It is also notoriously difficult for students to
understand, learn and apply. What makes this book different, and
special, is the clarity of the text. The writing style is fluid,
natural and lucid, and everything is explained in a logical and
transparent manner. Thermodynamics is a deep, and important, branch
of science, and this book does not make it "easy". But it does make
it intelligible. This book introduces a new, 'Fourth Law' of
Thermodynamics' based on the notion of Gibbs free energy, which
underpins almost every application of thermodynamics and which the
authors claim is worthy of recognition as a 'law'. The last four
chapters bring thermodynamics into the twenty-first century,
dealing with bioenergetics (how living systems capture and use free
energy), macromolecule assembly (how proteins fold), and
macromolecular aggregation (how, for example, virus capsids
assemble). This is of great current relevance to students of
biochemistry, biochemical engineering and pharmacy, and is covered
in very few other texts on thermodynamics. The book also contains
many novel and effective examples, such as the explanation of why
friction is irreversible, the proof of the depression of the
freezing point, and the explanation of the biochemical standard
state.
The marvellous complexity of the Universe emerges from several deep
laws and a handful of fundamental constants that fix its shape,
scale, and destiny. There is a deep structure to the world which at
the same time is simple, elegant, and beautiful. Where did these
laws and these constants come from? And why are the laws so
fruitful when written in the language of mathematics? Peter Atkins
considers the minimum effort needed to equip the Universe with its
laws and its constants. He explores the origin of the conservation
of energy, of electromagnetism, of classical and quantum mechanics,
and of thermodynamics, showing how all these laws spring from deep
symmetries. The revolutionary result is a short but immensely rich
weaving together of the fundamental ideas of physics. With his
characteristic wit, erudition, and economy, Atkins sketches out how
the laws of Nature can spring from very little. Or arguably from
nothing at all.

This book discusses the merging of nanoscale electronics and
electrochemistry and how this can potentially modernize the way
electronic devices are currently engineered or constructed. It
introduces the electrochemical capacitance as a fundamental missing
concept that solves the puzzle between molecular electronics and
electrochemistry at the nanoscale. The electrochemical capacitance,
as a fundamental principle, is deduced from first principles
quantum mechanics. The text also confirmed that faradaic and
non-faradaic processes are only different physical approximations
of the same sort of energetic phenomenon.The book comprises three
chapters. Chapter one introduces the concepts of chemical
capacitance, relaxation resistance, and the quantum
resistive-capacitive circuit and demonstrates how these elements
are translated to the electrochemistry context. In chapter two, the
chemical capacitance, the fundamental concept and missing part of
the puzzle that unity electronics and electrochemistry, is deduced
from first principles of quantum mechanics. In chapter three, the
concepts are practically used in different contexts that include
molecular diagnostics, molecular conductance and super-capacitive
phenomena is explained using the introduced basic principles.
Nicolae Vlad Burnete beschreibt ein neues Verbrennungsverfahren im
Dieselmotor, wobei eine Diesel-Voreinspritzung zu den
erforderlichen Selbstzundungsbedingungen einer
Ethanol-Haupteinspritzung fuhrt. Seine Ergebnisse zeigen, dass die
Schadstoffemissionen aufgrund einer geringeren Maximaltemperatur
erheblich verringert werden koennen, wahrend der Motorwirkungsgrad
aufgrund einer erhoehten Effizienz der Verbrennung gleichzeitig
erhoeht wird. Dieses essential ist ein geeigneter Beitrag fur eine
grundsatzliche Umstrukturierung der Fahrzeugantriebe, weil nicht
hauptsachlich die katalytische Nachbehandlung, sondern
grundsatzlich die Prozesse im Brennraum das hoechste Potenzial
dafur bieten.
This textbook covers the fundamentals of physical chemistry,
explaining the concepts in an accessible way and guiding the
readers in a step-by-step manner. The contents are broadly divided
into two sections: the classical physico-chemical topics
(thermodynamics, kinetics, electrochemistry, transport, and
catalysis), and the fabric of matter and its interactions with
radiation. Particular care has been taken in the presentation of
the algebraic parts of physico-chemical concepts, so that the
readers can easily follow the explanations and re-work relevant
discussion and derivations with pen and paper. The book is
accompanied by a rich mathematical appendix. Each chapter includes
a selection of (numerical) exercises and problems, so that students
can practice and apply the learned topics. An appendix with
solutions allows for controlling the learning success. Carefully
prepared illustrative color images make this book a great support
for teaching physical chemistry to undergraduate students.This
textbook mainly addresses undergraduate students in life sciences,
biochemistry or engineering, offering them a comprehensive and
comprehensible introduction for their studies of physical
chemistry. It will also appeal to undergraduate chemistry students
as an accessible introduction for their physical chemistry studies.
Based on the author's own work and results obtained by renowned
cosmologists, this short book provides a concise introduction to
the relatively new research field of cosmological thermodynamics.
Starting with a brief overview of basic cosmology and
thermodynamics, the text gives an interesting account of the
application of horizon thermodynamics to the homogeneous and
isotropic Friedmann-Lemaitre-Robertson-Walker (FLRW) model, the
inhomogeneous (Lemaitre-Tolman-Bondi) LTB model, and the
gravitationally induced adiabatic particle creation scenario which
is considered to be a viable alternative to the concordance
Lambda-CDM model of the Universe. Both seasoned and new researchers
in this field will appreciate the lucid presentation and the rich
bibliography.
This book offers a survey of the historic development of selected
areas of chemistry and chemical physics, discussing in detail the
European, American and Russian approaches to the development of
chemistry. Other key topics include the kinetics and non-linear
thermodynamics of chemical reactions and mathematical modeling,
which have found new applications in the theory of dynamical
systems. The first observations of the periodicity of chemical
reactions were lost in the mist of time. In the second half of the
19th century, the phenomenon of chemical periodicity was studied in
relation to electrochemistry, solutions and colloids. Discovered in
the late 19th century, Liesegang rings are still enigmatic and
remain attractive for researchers. However, the discovery of the
Belousov-Zhabotinsky reaction marked the successful culmination of
the efforts to find a true chemical oscillatory reaction. The book
investigates chemical phenomena that were neglected in the past,
but have been rediscovered, placing them into a new conceptual
framework. For example, it notes that William Bray, who discovered
the first oscillatory homogeneous reaction in 1921, was influenced
by the first bio-mathematicians who predicted chemical oscillations
in homogeneous systems.
This book provides deep insight into the physical quantity known as
chemical activity. The author probes deep into classical
thermodynamics in Part I, and then into statistical thermodynamics
in Part II, to provide the necessary background. The treatment has
been streamlined by placing some background material in appendices.
Chemical Activity is of interest not only to those in chemical
thermodynamics, but also to chemical engineers working with mass
transfer and its applications - for example, separation methods.
The first comprehensive graduate-level introduction to stochastic
thermodynamics Stochastic thermodynamics is a well-defined subfield
of statistical physics that aims to interpret thermodynamic
concepts for systems ranging in size from a few to hundreds of
nanometers, the behavior of which is inherently random due to
thermal fluctuations. This growing field therefore describes the
nonequilibrium dynamics of small systems, such as artificial
nanodevices and biological molecular machines, which are of
increasing scientific and technological relevance. This textbook
provides an up-to-date pedagogical introduction to stochastic
thermodynamics, guiding readers from basic concepts in statistical
physics, probability theory, and thermodynamics to the most recent
developments in the field. Gradually building up to more advanced
material, the authors consistently prioritize simplicity and
clarity over exhaustiveness and focus on the development of
readers' physical insight over mathematical formalism. This
approach allows the reader to grow as the book proceeds, helping
interested young scientists to enter the field with less effort and
to contribute to its ongoing vibrant development. Chapters provide
exercises to complement and reinforce learning. Appropriate for
graduate students in physics and biophysics, as well as
researchers, Stochastic Thermodynamics serves as an excellent
initiation to this rapidly evolving field. Emphasizes a pedagogical
approach to the subject Highlights connections with the
thermodynamics of information Pays special attention to molecular
biophysics applications Privileges physical intuition over

The Heat Equation is one of the three classical linear partial
differential equations of second order that form the basis of any
elementary introduction to the area of PDEs, and only recently has
it come to be fairly well understood. In this monograph, aimed at
research students and academics in mathematics and engineering, as
well as engineering specialists, Professor Vazquez provides a
systematic and comprehensive presentation of the mathematical
theory of the nonlinear heat equation usually called the Porous
Medium Equation (PME). This equation appears in a number of
physical applications, such as to describe processes involving
fluid flow, heat transfer or diffusion. Other applications have
been proposed in mathematical biology, lubrication, boundary layer
theory, and other fields. Each chapter contains a detailed
introduction and is supplied with a section of notes, providing
comments, historical notes or recommended reading, and exercises
for the reader.
