Based on the plenary and invited lectures presented at the
International Symposium on Micelles, Microemulsions, and
Monolayers, this title reviews the progress achieved over the years
and describes different directions for research on micellar,
microemulsion, and monolayer systems and their technological
potential.
This thesis investigates the effect of the magnetic field on
propagating surface plasmon polaritons (SPPs), or surface plasmons
for short. Above all, it focuses on using the magnetic field as an
external agent to modify the properties of the SPPs, and therefore
achieving active devices. Surface plasmons are evanescent waves
that arise at metal-dielectric interfaces. They can be strongly
confined (beyond the light diffraction limit), and provide a strong
enhancement of the electromagnetic field at the interface. These
waves have led to the development of plasmonic circuitry, which is
a key candidate as an alternative to electronic circuitry and
traditional optical telecommunication devices, since it is faster
than the former and less bulky than the latter. Adopting both a
theoretical and an experimental point of view, the book analyzes
the magnetic modulation in SPPs by means of an interferometer
engraved in a multilayer combining Au and Co. In this
interferometer, which acts like a modulator, the SPP magnetic
modulation is studied in detail, as are the parameters that have a
relevant impact on it, simple ways to enhance it, its spectral
dependence, and the highly promising possibility of using this
system for biosensing. The thesis ultimately arrives at the
conclusion that this method can provide values of modulations
similar to other active methods used in plasmonics.
This volume provides the latest developments in the field of
surface science and technology based on diazonium coupling agents
as well as their precursors (e.g. aromatic amines). It presents new
concepts of surface chemistry of diazonium salts and discusses
their novel and challenging applications. The latest advances on
surface modification with diazonium salts are discussed and various
promising alternative surface modifiers such as iodonium salts are
examined. This book demonstrates the universality of diazonium
salts in the surface treatment of classical and emergent materials
and it will be a great tool for researcher and graduates working in
this field.
Corrosion is a high-cost and potentially hazardous issue in
numerous industries. The potential use of diverse carbon
nanoallotropes in corrosion protection, prevention and control is a
subject of rising attention. This book covers the current
advancements of carbon nanoallotropes in metal corrosion
management, including the usage of nanostructure materials to
produce high-performance corrosion inhibitors and
corrosion-resistant coatings.
At the beginning of the twentieth century, engineers and
technologists would have recognized the importance of adhesion in
two main aspects: First, in the display of friction between
surfaces - at the time a topic of growing importance to engineers;
the second in crafts requiring the joining of materials -
principally wood-to form engineering structures. While physical
scientists would have admitted the adhesive properties of glues,
gels, and certain pastes, they regarded them as materials of
uncertain formulation, too impure to be amenable to precise
experiment. Biological scientists were aware also of adhesive
phenomena, but the science was supported by documentation rather
than understanding. By the end of the century, adhesion and
adhesives were playing a crucial and deliberate role in the
formulation of materials, in the design and manufacture of
engineering structures without weakening rivets or pins, and in the
use of thin sections and intricate shapes. Miniaturization down to
the micro- and now to the nano-level of mechanical, electrical,
electronic, and optical devices relied heavily on the understanding
and the technology of adhesion. For most of the century, physical
scientists were aware that the states of matter, whether gas,
liquid, or solid, were determined by the competition between
thermal energy and int- molecular binding forces. Then the solid
state had to be differentiated into crystals, amorphous glasses,
metals, etc. , so the importance of the molecular attractions in
determining stiffness and strength became clearer.
The purpose of this book is to stimulate thinking among corrosion
scientists and engineers to examine corrosion mechanisms and corro
sion control from another perspective. While the presence of corro
sion films in electrochemical corrosion has been recognized for
over a century, the contribution of these films to all facets of
corrosion has not been explored to a significant degree. Rather the
role of films in certain mechanisms (i.e., stress corrosion
cracking) has been empha sized, yet almost ignored for other
corrosion mechanisms. This is viewed by the author as solely
attributable to the lack of investigation into, and an
understanding of, the contribution of films to these mech anisms or
forms of attack. The lack of emphasis and study of corrosion films
and their contribution to all forms of corrosion attack are
probably the result of current university instruction that utilizes
two popular corrosion texts (Uhlig and Fontana and Greene) for
teaching. These texts provide an excellent understanding at the
undergraduate level of corrosion funda mentals; however, the major
implicit premise in these texts is that bulk properties of an alloy
or metal control the corrosion resistance in a particular
environment. For many applications and for a simple under standing
of corrosion mechanics, this approach is sufficient. Yet, research
on corrosion films indicate these films often have an entirely
different composition than the bulk metal (ratio of alloying
elements)."
This volume discusses the role of ZIF-8 composites in water
decontamination as an adsorbent and photocatalyst. Metal-organic
frameworks (MOFs) are advanced porous materials and are promising
adsorbents with facile modifications, high specific surface area,
controllable porosity, and tailored surface properties. Water
pollution is a major concern and has endangered human health.
Recently, researchers have designed MOFs for use in remediation.

This book takes an interface science approach to describe and
understand the behavior of the dispersions we call emulsions,
microemulsions and foams. The one thing all these dispersions have
in common is the presence of surface-active species (surfactants)
adsorbed at the interfaces between the two fluid phases that make
up the emulsions, microemulsions or foams. The interfacial layers
formed by the surfactants control most of the properties of the
dispersions. The book describes the properties of interfacial
layers, thin films and bulk fluids used in the elaboration of the
various dispersions and it explains how such properties relate to
the dispersion properties of these soft matter systems: structure,
rheology and stability. These dispersion properties are far from
being fully understood, in particular foam and emulsion stability.
In discussing the state of the art of the current knowledge, the
author draws interesting parallels between emulsions,
microemulsions and foams that enlighten the interpretation of
previous observations and point to a deeper understanding of the
behavior of these materials in the future.
Handbook of Modern Coating Technologies: Fabrication Methods and
Functional Properties reviews different fabrication methods and
functional properties of modern coating technologies. The topics in
this volume consist of nanocoatings by sol-gel processes for
functionalization of polymer surfaces and textiles and mechanical
fabrication methods of nanostructured surfaces such surface
mechanical attrition treatment, polymer nanofabrications and its
plasma processing, chemical vapor deposition of oxide materials at
atmospheric pressure, conventional chemical vapor deposition
process at atmospheric pressure, feasibility of atmospheric
pressure, chemical vapor deposition process, Langmuir-Blodgett
technique, flame pyrolysis, confined-plume chemical deposition,
electrophoretic deposition, in vitro and in vivo particle coating
for oral targeting and drug delivery, novel coatings to improve the
performance of multilayer biopolymeric films for food packaging,
corrosion protection by nanostructured coatings, tribological
behavior of electroless coatings, effect of peening-based processes
on tribological and mechanical behavior of bioimplant materials,
improved efficiency of ceramic cutting tools in machining hardened
steel with nanostructured multilayered coatings, incorporation of
elastomeric secondary phase into epoxy matrix influences mechanical
properties of epoxy coatings, enhancement of biocompatibility by
coatings, porous hydroxyapatite-based coatings, and bionic
colloidal crystal coatings.
Monomolecular assemblies on substrates, now termed
Langmuir-Blodgett (LB) films, have been studied for over half a
century. Their development can be viewed in three stages. Following
the pioneering work of Irving Langmuir and Katharine Blodgett in
the late 1930s there was a brief flurry of activity just before and
just after the Second World War. Many years later Hans Kuhn
published his stimulating work on energy transfer. This German
contribution to the field, made in the mid-1960s, can be regarded
as laying the foundation for studies of artificial systems of
cooperat ing molecules on solid substrates. However, the resurgence
of activity in academic and industrial laboratories, which has
resulted in four large international con ferences, would not have
occurred but for British and French groups highlighting the
possible applications of LB films in thefield of electronics. Many
academic and industrial establishments involved in high technology
are now active in or maintaining a watching brief on the field.
Nevertheless this impor tant area of solid state science is still
perhaps largely unfamiliar to many involved in materials or
electronic device research. The richness of the variety of organic
molecular materials suitable for LB film deposition offers enormous
scope for those interested in their basic properties or their
practical applications. LB films are now an integral part of the
field of molecular electronics. It seems inevitable that they will
play some role in replacing inorganic materials in certain areas of
application."
Fundamentals of Adsorption is the proceedings of the fifth
International Conference on the Fundamentals of Adsorption, which
was held on May 13-18, 1995 at the Asilomar Conference Center,
Pacific Grove, California. This conference was organized completely
under the auspices of the International Adsorption Society. It was
attended by 196 participants from 24 countries. Members of the
Scientific Advisory Board, together with the Conference Committee,
selected papers for presentation from a large number of proposals
involving an especially high level of international participation.
The fundamental aspects of adsorption is a subject which has grown
rapidly in recent years, drawing researchers from many disciplines
including materials science, chemistry, physics, biochemistry and
biotechnology, and chemical, civil, mechanical and environmental
engineering. Fundamentals of Adsorption serves as an excellent
reference and may be used as a primary text for a graduate level
course on adsorption research or as a secondary text for a course
on any of the disciplines mentioned above.
This book aims at identifying novel advanced materials of extreme
wetting properties (MEWP) for practical, industrial applications.
The state-of-the art superhdyrophobic, superhdyrophilic,
superoleophobic, superoleophilic, and superomniphobic materials,
that are MEWP, with respect to their technological and emerging
industrial applications are discussed in this book. MEWP offer new
perspectives providing numerous potential applications. Hence,
these advanced MEWP have the potential to lead to a new generation
of products and devices with unique properties and functionalities.
Despite the large scientific progress on MEWP there are still some
obstacles which have to be solved to make these materials available
for real life applications. Recent advances on the production
strategies, including methods and materials, of MEWP has shown that
the durability and sustainability obstacles can be addressed thus
offering the possibility for industrial exploitation. MEWP with
wettabilities ranging from superhydrophobicity to
superhydrophilicity provide promising avenues for several and
important applications, which sometimes are crucial for the
humankind. This book also discusses a large variety of other
potential applications of MEWP, thus providing new ideas to
scientists and engineers for further exploitation of these novel
materials. Moreover, the whole spectrum of the recent technological
developments, current research progress, future outlook, and the
modern trends in the applications of MEWP are discussed in a
consistent approach.
This book presents the optimal auxiliary functions method and
applies it to various engineering problems and in particular in
boundary layer problems. The cornerstone of the presented procedure
is the concept of "optimal auxiliary functions" which are needed to
obtain accurate results in an efficient way. Unlike other known
analytic approaches, this procedure provides us with a simple but
rigorous way to control and adjust the convergence of the solutions
of nonlinear dynamical systems. The optimal auxiliary functions are
depending on some convergence-control parameters whose optimal
values are rigorously determined from mathematical point of view.
The capital strength of our procedure is its fast convergence,
since after only one iteration, we obtain very accurate analytical
solutions which are very easy to be verified. Moreover, no
simplifying hypothesis or assumptions are made. The book contains a
large amount of practical models from various fields of engineering
such as classical and fluid mechanics, thermodynamics, nonlinear
oscillations, electrical machines, and many more. The book is a
continuation of our previous books "Nonlinear Dynamical Systems in
Engineering. Some Approximate Approaches", Springer-2011 and "The
Optimal Homotopy Asymptotic Method. Engineering Applications",
Springer-2015.
This book offers a comprehensive treatment of the molecular design,
characterization, and physical chemistry of soft interfaces. At the
same time, the book aims to encourage the fabrication of functional
materials including biomaterials. During the past few decades there
has been steady growth in soft-interface science, and that growth
has been especially rapid in the twenty-first century. The field is
interdisciplinary because it involves chemistry, polymer science,
materials science, physical chemistry, and biology. Based on the
increasing interdisciplinary nature of undergraduate and graduate
programs, the primary goal of this present work is to serve as a
comprehensive resource for senior-level undergraduates and for
graduate students, particularly in polymer chemistry, materials
science, bioconjugate chemistry, bioengineering, and biomaterials.
Additionally, with the growing interest in the fabrication of
functional soft materials, this book provides essential fundamental
information for researchers not only in academia but also in
industry.
Introduction to Adsorption: Basics, Analysis, and Applications
presents adsorption basics that are relevant and essential to its
application, including data analysis, interpretation and design
calculations. The book deliberately keeps background information to
a minimum, instead comprehensively covering adsorption of liquid
solutions, the difference between equilibrium individual solute
uptake and surface excess, a general discussion of adsorbate uptake
mechanisms and uptake rate expression, uptake steps, performance
models and their generalizations, application of performance
models, and design methods based on the constant behavior
assumption and unused bed length concept.
This book presents contributions on a wide range of computational
research applied to fields ranging from molecular systems to bulk
structures. This volume highlights current trends in modern
computational chemistry and discusses the development of
theoretical methodologies, state-of-the-art computational
algorithms and their practical applications. This volume is part of
a continuous effort by the editors to document recent advances by
prominent researchers in the area of computational chemistry. Most
of the chapters are contributed by invited speakers and
participants to International annual conference "Current Trends in
Computational Chemistry", organized by Jerzy Leszczynski, one of
the editors of the current volume. This conference series has
become an exciting platform for eminent theoretical and
computational chemists to discuss their recent findings and is
regularly honored by the presence of Nobel laureates. Topics
covered in the book include reactive force-field methodologies,
coarse-grained modeling, DNA damage radiosensitizers, modeling and
simulation of surfaces and interfaces, non-covalent interactions,
and many others. The book is intended for theoretical and
computational chemists, physical chemists, material scientists and
those who are eager to apply computational chemistry methods to
problems of chemical and physical importance. It is a valuable
resource for undergraduate, graduate and PhD students as well as
for established researchers.
Tailored Thin Coatings for Corrosion Inhibition Using a Molecular
Approach discusses the fundamentals and applications of various
thin coatings for the inhibition of fouling and corrosion from a
molecular perspective. It provides the reader with a fundamental
understanding of why certain coatings perform better than others in
a given environment. Surface analytical and electrochemical
techniques in understanding the coating performance are emphasized
throughout the book, providing readers with a useful reference on
how to pursue a systematic corrosion inhibitor R&D program that
involves the testing of coating performance using various,
currently available, state-of-the-art laboratory techniques.
Wherever relevant, environmental considerations of the discussed
coatings' technologies are highlighted and discussed, with current
and upcoming regulatory trends put forth by different governmental
organizations.
This book presents recent material science-based and mechanical
analysis-based advances in joining processes. It includes all
related processes, e.g. friction stir welding, joining by plastic
deformation, laser welding, clinch joining, and adhesive bonding,
as well as hybrid joints. It gathers selected full-length papers
from the 1st Conference on Advanced Joining Processes.
This book presents the select proceedings of the International
Conference on Functional Material, Manufacturing and Performances
(ICFMMP) 2019. The book covers broad aspects of several topics
involved in the metrology and measurement of engineering surfaces
and their implementation in automotive, bio-manufacturing,
chemicals, electronics, energy, construction materials, and other
engineering applications. The contents focus on cutting-edge
instruments, methods and standards in the field of metrology and
mechanical properties of advanced materials. Given the scope of the
topics, this book can be useful for students, researchers and
professionals interested in the measurement of surfaces, and the
applications thereof.
This book introduces the fascinating world of self-assembly in
mesoporous ordered silica films. Beginning from a single droplet,
it guides the reader, in a step-by-step learning process, how to
obtain and control ordered porous mesophases in thin films by
varying only the precursor chemistry and the process. It explains,
in great detail, how order control is achieved through chemical
design and post-deposition processing, the latter of which is a
unique property in materials science. The book places a special
focus on silica, whose particularly complex chemistry enables order
control over a range of different length scales. This book is
suitable for students and researchers in the fields of sol-gel or
colloidal chemistry and interested in the topics of self-assembly
and mesoporous phases.
THE CURRENT STATE OF THE ART of waterborne polymers, paints,
coatings, inks and printing processes is presented in this volume.
This is the third volume in the series on waterborne coating and
printing technology. It documents several invited papers and the
proceedings of the International Symposium on Surface Phenomena and
Latexes in Waterborne Coatings and printing Technology sponsored by
the Fine Particle Society (FPS). The FPS meeting was held in Las
Vegas, Nevada, July 13-17, 1992. The volume deals with various
basic and applied aspects of research on waterborne coating
printing technology. Major topics discussed involve waterborne
polymers and polymer blends, pigment grinding, millbases, paint
formulation, and characterization of coating films. This edition
includes sixteen selected papers related to recent developments in
waterborne technology. These papers are divided in three broad
categories: (1) Waterborne Polymers and pigment Dispersions, (2)
Latex Film, Wetting Phenomena and Printing Gloss, (3) Surfactants
and Polymers in Aqueous Coating printing Systems. This volume
includes discussions of various waterborne polymers in coating
printing systems. The editors hope that this volume will serve its
intended objective of reflecting the current understanding of
formulation and process problems related to waterborne coatings,
paints and inks. In addition, it will be a valuable reference
source for both novices as well as experts in the field of
waterborne technology. It will also help the readers to understand
underlying surface phenomena and will enhance the reader's
potential for solving critical formulation, evaluation and process
problems.
This thesis considers molecular orientation in thin films and
introduces an optical model describing this orientation as applied
to organic light-emitting diodes (OLEDs). It also describes the
electronic structure of intermolecular charge transfer excitons
correlated to molecular orientation in solids. It has long been
known that molecular orientation influences the electrical and
optical properties of molecular films. One notable example is in
liquid crystals where rigid rod or disk shaped molecules are
commonly used. Understanding the origin of the molecular
orientation and its control by surface treatment and electric field
resulted in the development of liquid crystal displays. The same
thing has happened in organic electronics, and considerable effort
has been devoted to understanding and controlling molecular
orientation in solid films to improve charge carrier mobility and
light absorption, ultimately to improve the performance of organic
solar cells and thin film transistors. In contrast, less attention
has been paid to molecular orientation and its influence on the
characteristics of OLEDs, probably because of the use of amorphous
films rather than micro-crystalline films, and it is only in recent
years that some molecular films are known to have preferred
orientation. This thesis addresses this topic, focusing on OLEDs,
describing the origin and control of the orientation of
phosphorescent Ir complexes possessing spherical shape rather than
rod or disk shape, the simulation of the optical characteristics of
OLEDs influenced by preferred molecular orientation, and finally
the orientation of intermolecular charge transfer excitons and its
correlation to electronic structures in thin films.
