This thesis examines electrode materials such as mesoporous carbons, manganese oxides, iron oxides and their nanohybrids with graphene. It also explores several of the key scientific issues that act as the governing principles for future development of supercapacitors, which are a promising class of high-efficiency energy storage devices for tackling a key aspect of the energy crisis. However, critical technical issues, such as the low energy density and reliability, need to be addressed before they can be extended to a wide range of applications with much improved performance. Currently available material candidates for the electrodes all have their disadvantages, such as a low specific capacitance or poor conductivity for transition metal oxide/hydroxide-based materials. This thesis addresses these important issues, and develops a high-performance, flexible asymmetric supercapacitor with manganese oxides/reduced graphene oxide as the positive electrode and iron oxide/reduced graphene oxide as the anode, which delivers a high energy density of 0.056 Wh cm-3.

Davydov was held in Kiev, Ukraine, on 8-12 June, 2008, at the Bogolyubov Institute for Theoretical Physics of the National Academy of Sciences of Ukraine. Theobjective ofthisNATOARWistounveilandformulatetheprincipalfeatures that govern myriads of the molecular self-organization processes in micro-, nano-, and macro-dimensions from the following key representatives such as liquid - ter and aqueous solutions, and molecular liquids, nanodots, nanoparticles including gold, solitons, biomolecules such as DNA and proteins, biopolymers and bios- sors, catalysis, molecular modeling, molecular devices, and thin ?lms, and to offer another, more advanced directions in computational, experimental, and technolo- cal areas of nano- and bioscience towards engineering novel and powerful molecular self-organized assemblies with tailored properties. Nanoscience is indeed one of the most important research and development fr- tiers in modern science. Simplistically, nanoscience is the science of small particles of materials of a size of nanometre. Molecular nanoscience and nanotechnology have brought to us the unprecedented experimental control of the structure of matter with novel extraordinary properties that open new horizons and new opportunities, and new ways to make things, particularly in our everyday life, to heal our bodies, and to care of the environment. Unfortunately, they have also brought unwelcome advances in weaponry and opened yet more ways to foul up the world on an en- mous scale.

This book discusses emerging nanotechnology-based tools that have the potential to dramatically impact cancer research, diagnostics, and treatment. Cancer is a complex, devastating, and debilitating disease and, although much progress has been made, novel, more effective diagnostic and treatment options are still needed, especially for advanced cancers. The ultimate goal is to detect cancer early and non-invasively and to provide efficacious and targeted precision treatments that cause fewer harmful side effects. This book explains how nanotechnology can exploit the size-, shape-, and composition-dependent properties of nanomaterials to provide novel tools for precision cancer medicine. It will be of interest to researchers and professionals working in the fields of chemistry, biology, materials science and engineering, and medicine who want to learn more about this fascinating and fast-paced area of research.
Metallic nanoparticles display fascinating properties that are
quite different from those of individual atoms, surfaces or bulk
rmaterials. They are a focus of interest for fundamental science
and, because of their huge potential in nanotechnology, they are
the subject of intense research effort in a range of disciplines.
Applications, or potential applications, are diverse and
interdisciplinary. They include, for example, use in biochemistry,
in catalysis and as chemical and biological sensors, as systems for
nanoelectronics and nanostructured magnetism (e.g. data storage
devices), where the drive for further miniaturization provides
tremendous technological challenges and, in medicine, there is
interest in their potential as agents for drug delivery.
"Neutron Applications in Materials for Energy "collects results and conclusions of recent neutron-based investigations of materials that are important in the development of sustainable energy. Chapters are authored by leading scientists with hands-on experience in the field, providing overviews, recent highlights, and case-studies to illustrate the applicability of one or more neutron-based techniques of analysis. The theme follows energy production, storage, and use, but each chapter, or section, can also be read independently, with basic theory and instrumentation for neutron scattering being outlined in the introductory chapter. Whilst neutron scattering is extensively used to understand properties of condensed matter, neutron techniques are exceptionally-well suited to studying how the transport and binding of energy and charge-carrying molecules and ions are related to their dynamics and the material s crystal structure. These studies extend to "in situ" and "in operando" in some cases. The species of interest in leading energy-technologies include H2, H+, and Li+ which have particularly favourable neutron-scattering properties that render these techniques of analysis ideal for such studies and consequently, neutron-based analysis is common-place for hydrogen storage, fuel-cell, catalysis, and battery materials. Similar research into the functionality of solar cell, nuclear, and CO2 capture/storage materials rely on other unique aspects of neutron scattering and again show how structure and dynamics provide an understanding of the material stability and the binding and mobility of species of interest within these materials. Scientists and students looking for methods to help them understand the atomic-level mechanisms and behaviour underpinning the performance characteristics of energy materials will find "Neutron Applications in Materials for Energy "a valuable resource, whilst the wider audience of sustainable energy scientists, and newcomers to neutron scattering should find this a useful reference. "

This second volume in the Handai Nanophotonics book series covers
the area of Nanoplasmonics, a recent hot topic in the field of
nanophotonics, impacting a diverse range of research disciplines
from information technology and nanotechnology to the bio- and
medical sciences. The interaction between photons and metal
nanostructures leads to interesting and extraordinary scientific
phenomena and produces new functions for nano materials and
devices. Newly discovered physical phenomena include local mode of
surface plasmon polariton excited in nanoparticles, hot spots on
nano-rods and nano-cones, long range mode of surface plasmons
excited on thin metal films, and dispersion relationship bandgaps
of surface plasmons in periodic metal structures. These have been
applied to, for example, single molecule detection and
nano-imaging/spectroscopy, photon accumulation for lasing
applications, optical nano-waveguides and nano-circuits.
The volumes VIII, IX and X examine the physical and technical foundation for recent progress in applied scanning probe techniques. This is the first book to summarize the state-of-the-art of this technique. The field is progressing so fast that there is a need for a set of volumes every 12 to 18 months to capture latest developments. These volumes constitute a timely comprehensive overview of SPM applications.

This thesis outlines the first synthesis of a new complex branched polymer architecture that aims to combine the benefits of dendrimers with the simplicity of conventional polymerisation. There is no other available literature on these remarkable materials, dubbed hyperbranched polydendrons, due to their novelty. The new materials were shown to have very high molecular weights (>1,000,000 g/mol), exceptional self-assembly and encapsulation behaviour and unparalleled functionalisation capabilities, and were studied pharmacologically to determine their potential as oral nanomedicine candidates. The detailed investigation of the chemical variables involved in synthesising hyperbranched polydendrons has shown that their self-assembly and pharmacological behaviour can be turned on and off and fine-tuned by altering the composition of the materials. The permeation of the self-assembled particles through model gut epithelium suggests the potential for oral dosing of drug loaded nanomedicines that result in circulating nanoparticles - a research goal that is currently being pursued by several groups around the globe.
Nanofiltration processes are finding wide applications in several
'wet' industries, such as water/wastewater treatment, water re-use,
textile industry, diary industry, food industry and the pulp and
paper industries. Despite this, no definitive book exists which
covers the principles of the techniques and their potential and
actual applications.
Nanotechnology is the science of designing and building machines at the molecular and atomic levels.Dr. Hall - a leading researcher on the frontiers of nanotechnology who has designed for NASA - describes nanotechnology in a very accessible way, so that anyone can understand what it's about, what it could do, and what it can't do. He puts it into historical context, explaining how previous technological developments have affected us, how nanotechnology fits into the historical trends for technologies ranging from motors to medicine, and how the continuation of these trends, with nanotechnology as a strong determining factor, will have a profound impact on the future. Together with its sister science of biotechnology, nanotechnology has the potential to alter the very human race, change who we are. Can this possibly be good? Should it be encouraged or opposed? No one knows for sure, but the basis for informed thought can be found in these exciting, stimulating pages, which will open the doors of the future to you. |
