~~304,75€~~ 243,80€ 20% IMEDIATO

DISPONIBILIDADE IMEDIATA

 Nanosensors refer to a miniature electronic sensing device that works on a "Nano-scale" region. A nanosensor is a device that can transfer information and data on the behaviour and characteristics of tiny particles to a higher degree of visibility. Nanosensors can be used to distinguish chemical or mechanical data, such as the presence of material species and nanoparticles, or to screen real limitations on the nanoscale, such as temperature. Nanosensors are categorised depending on their design and intended use. Based on their structure, nanosensors are classified into two types: optical nanosensors and electrochemical nanosensors. Depending on the application, the nanosensor can be purchased as a material nanosensor, biosensor, electrometer, or deployable nanosensor. Nanosensors can measure down to the level of a single particle. Nanosensors include an analyte, sensor, transducer, and indicator. Nanosensors work by continuously monitoring electrical changes in sensor materials. The analyte diffuses from the solution for the sensor''s outer layer and responds explicitly and competently, changing the physicochemical properties of the transducer surface, prompting an adjustment of the optical or electronic properties of the transducer''s outer layer, and this change is converted into an electrical sign that is recognized. Like new technology, intelligent healthcare systems are moving toward new approaches and models of healthcare-based nanosensors, smart phones, smart watches, and other gadgets. This book deeply discusses the deployment of nanomaterials and nanosensors to enhance the healthcare system with continuous and real-time monitoring of individuals to avoid huge life risks. Environmental pollution has become a serious global issue affecting public health, the economy, and society. Organic pollutants, heavy metals in the soil, pesticide intake from fruits and vegetables, and the influence of illnesses and their toxins are all considered serious environmental problems. This book focuses on current advancements in DNA-nanosensors for environmental monitoring that make tracking contaminants simpler. DNA nanosensors are used to detect harmful microbiological contaminants, toxins, and medications. Some contemporary DNA-nanosensor environmental monitoring applications are discussed.

DISPONIBILIDADE IMEDIATA

 Recent discoveries have given rise to a new class of electronics known as "spin electronics" or "spintronics," which uses the electron spin rather than its charge to create polarized currents. Spintronics is currently experiencing an extraordinary development with the manufacture of nanoscale devices based on ferromagnetic materials and semiconductors. Their applications are numerous, ranging from recording, electronics, and optoelectronics to quantum information. Spintronics is a new generation of electronics that has brought and continues to bring a lot of progress to information storage; this is due to the discovery of new materials with new functionalities and multiple applications. The discovery of giant magnetoresistance (GMR) in 1988 by Albert Fert and Peter Grunberg (receiver of the Nobel Prize in Physics in 2007) is considered a starting point of spintronics. GMR is based on the variation of the electric current in the presence of a magnetic field. The spintronics has made important contributions to the miniaturization desired for electronics; it uses nanometric components for processing and storing information. However, the limits of miniaturization on a nanometric scale are known, and it is imperative to develop new ways and new materials to exceed those limits. The most desired properties for these materials are high spin polarization, modular magnetic properties by an electric field and a long lifetime of the spin polarization. Among the new promising materials, we cite the following: Diluted magnetic semiconductors, which give new magnetic properties of conventional semiconductors, functional oxides (including the semi-metals and multiferroic metals) and organic semiconductors. The main theoretical challenge in this area is to understand how the macroscopic magnetic behavior observed results from interactions of a large number of degrees of microscopic freedom. In these systems the disorder is an essential parameter of magnetic phenomena, and due to random locations of impurity atoms it can lead to a total physical difference from the observed absence. There has been considerable recent advances in the design of these materials as diluted magnetic semiconductors (DMS, or diluted magnetic semiconductors), and a number of semiconductors were investigated as II-VI group and III-V group doped compounds, with transition metals substituting their original cations. There are several different theoretical approaches to study these magnetic materials. The ab-initio approach starts from the Schrodinger equation to simulate a given material. Such an approach is essential to determine the parameters and microscopic properties of such a system. In this book, the authors analyzed the electronic structure of magnetic semiconductors diluted in the case of ZnO, GaN, SnO2, TiO2, MgH2, EuO and EuN doped RENs (RE=GdN, DyN and HoN). The authors focused on magnetic, optical and exchange mechanisms which control the ferromagnetism in these systems. The purpose of this book is to propose some ideas to answer the most important question in material science for semiconductor spintronics, primarily considering how room-temperature ferromagnetism in DMS can be realized. Additionally, the correlation between first principle and experimental design to see how properties of yet-to-be-synthesized materials can be predicted is discussed.

Introduction Of Forensic Nanotechnology As Future Armour

~~258,38€~~ 206,70€ 20% IMEDIATO

DISPONIBILIDADE IMEDIATA

 Forensic Science is an interdisciplinary subject that uses principles and methodologies of various subjects including chemistry, biology, physics, geology, psychology, social science and engineering to help law enforcement agencies to enforce criminal laws and regulations to resolve civil and criminal cases. Body fluids, fingerprints, footprints, illicit drugs, explosives etc. are the evidences that can be found at the scene of crime in trace amount. These evidences are first analysed through screening and then confirmatory methods. During this process, the probability of sample loss is very high, especially when a sample amount is inadequate and therefore does not meet minimum requirement to analyse it. Generally, scientists discuss new-fangled nanotechnology research and its conversation turns to the commercial aspects or potential issues around health, safety, and the environment. In recent years, some of them have shown their interest to integrate nanotechnology with basic sciences and applied for forensic purposes, which are shifting the paradigm of forensic investigation process. Introduction of Forensic Nanotechnology as Future Armour is the first comprehensive book to consider both fundamental and applied aspects of forensic nanotechnology. This emerging field of forensic science investigates real-time crime scenes and terrorist activities, inquiries, detects the presence of explosive materials, biological indicators, document preservation, fingerprint enhancement and food adulteration using nanomaterial. Scientists and researchers are working on nanotechnology applications that may steer the power of forensic investigation, but the challenges to bring them from lab to the courtroom remain persistent. Moreover, some crucial concerns in forensic science such as analysis cost and time, methods’ effectiveness and wide availability and results’ accuracy and reliability are creating obstacles in forensic investigation and security. In this book we requested to enrich the scientific content as state-of-the-art in terms of application of nanotechnology in forensic science. In this way, all chapters will emphasise the emerging field of research to solve crime with the help of nanotechnology in various fields of forensic science like detecting explosives, biological indicators, document preservation, latent fingerprint and food adulteration. The integration of laboratory processes onto a nano platform is conceivably the most interesting advancement of nanotechnology highlighted in this book and some more issues like recent research developments, challenges and future opportunities are also addressed in this book. The book is written for a wide readership including researchers, undergraduate and graduate students from diverse backgrounds such as chemistry, materials science and nanotechnology engineering, physics, life sciences, forensic science, and biomedical engineering. It can be used not only as a textbook but also as a review and reference book. However, because many other nano technological applications for forensic analysis are yet to be studied, this book can be helpful to explore new opportunities. We hope that the chapters of this book will provide the reader with valuable insight as a revolutionary, protective tool in the fields of virtopsy, crime scene investigation, identification, forensic biology and toxicology. We also hope that after reading this book, researchers around the world will be motivated to enter into the field of forensic nanotechnology.

 This volume of a book "Applied Aspects of Nanophysics and Nano-engineering" is partially composed of short communications - proceedings of international symposium "Nanophysics and nano-engineering 2017" (venue: Mining university), and full-sized chapters, covering selected topics in depth. A variety of phenomena are described in this book. Smart nanostructured coatings, methods of synthesis based on both "top to bottom" (plasma deposition, remote methods) and "bottom to top" approaches are covered, as well as modeling approaches and analytical techniques. As before, ecological issues are highly addressed, such as materials for water purification and pollution prevention. Permanent interest in fullerenes as to one-dimensional carbon-based structures arises from their ability to be relatively easily modified by species of interest, for the purpose of bio-substrate delivery. Graphite exfoliation is utilized as a method to produce graphite nanoparticles and the modelling of fullers is reported. Issues of dielectric relaxation of solids have been a stunning topic for at least a few decades, and even now the interest in the dielectric relaxation approach seems to increase. This is because of the sensitivity of this non-destructive method to the conformational changes of flexible molecular moieties, brushes, and interchain segments. This avenue was focused on materials appliances of the method and technical development of the method and resolution, as well as the materials studied. Semiconductor technologies discussed in the book were related to developing solar concentrator systems (silicon technologies), heterojunction solar cells of eutectic gallium arsenide solid solutions for the development of alternative heterostructures based on the tunneling effect. "Exotic" semiconductors - diamonds with delta-doped layers known for their high temperature resistance - are studied via capacitance measurements. Directional crystallization was studied to produce rear-Earth compounds with anisotropic properties for the application of thermoelectric materials. Findings in sorption properties of clay minerals with singlet oxygen is underestimated as global in terms of environmental factors. Oil shale and oil shale ash Baltic basin studies are reported. Materials with magnetic properties synthesized by the sol-gel method are based on varrium-titanium ceramic and are studied via a variety of powerful experimental methods: SEM, XRD, SAXC, and SAPNS. Findings in the surface modification of zinc oxide films are modified by selenium. A special experimental setup is made possible using an ambient pressure approach without isolating the atmosphere to synthesize the hierarchically ordered surface structure. Interface properties related to water absorption on an aluminum surface are analyzed, and they are of interest for tribology applications of organopolymer compositions. Composite nanostructured materials for solar concentrator systems are discussed, as well as compounds for thermionic energy converters. It is believed that this book provides an unbiased sketch of progress in nanotechnology and related areas.

Surface-Enhanced Raman Spectroscopy: Methods, Analysis And Research

~~258,38€~~ 206,70€ 20% IMEDIATO

DISPONIBILIDADE IMEDIATA

 In the last decade, we have seen spurring growth in academic and industrial interest in Raman spectroscopy and its modifications, in particular, Surface-Enhanced Raman Spectroscopy (SERS). This is evident by the number of SERS publications in the last decade, from 580 in 2005 to almost 2000 in 2014. There are now companies worldwide that are dedicated to manufacturing SERS substrate, sensors, and other SERS-based products. The miniaturization of Raman instrumentation from bulky and expensive bench-top designs to inexpensive handheld spectrometers has allowed SERS to be employed as an in situ detection technique. Some examples of the industrial success of Raman and SERS are rapid raw material identification (RMID), Process Analytical Technology (PAT) and drug screening in pharma and biotech industries, continuous surveillance of food, water, and environmental safety, and the diagnosis and continuous monitoring of diseases like cancer, diabetes, etc. This progress in translating Raman and SERS techniques into commercial use and commercial products is possible because of the close collaboration between scientists and engineers. However, the weak signals of Raman spectroscopy is an inherent limitation of the spontaneous Raman spectroscopy technique. Therefore, several modifications have been made, including but not limited to, surface-enhanced Raman spectroscopy (SERS), spatially offset Raman spectroscopy (SORS), transmission Raman spectroscopy (TRS), coherent anti-Stoke’s Raman spectroscopy (CARS), and tip-enhanced Raman spectroscopy (TERS). Spontaneous Raman spectroscopy has become a one-of-a kind, portable, and affordable technology for in-situ detection and continuous monitoring in resource-limited-settings. The primary focus of this textbook is to try to cover the fundamentals in SERS methods of preparing substrates and sensors, and efficient spectral analysis approaches like chemometrics for diverse applications, listed in the paragraph above. However, with a goal to give a true picture to the audience when assessing the scope of spontaneous Raman and Surface-enhanced Raman for specific applications, we have briefly introduced industrially successful examples of other types of Raman spectroscopy techniques, such as SORS, TRS, and CARS.

DISPONIBILIDADE IMEDIATA

 The first-principle approach is designed for the interpretation of the experimental observations and prediction of properties for new nanomaterials. The understanding of physical phenomena requires a description at the atomic scale where size and geometric organization play important roles. The major challenge is to model systems as close as possible to those developed in the laboratory. The complexity both in terms of the geometric structure and chemical composition that comprise the modeling of such systems requires an entire panel of approaches ranging from semi-empirical methods to ab initio methods. At the atomic scale, the elementary bricks of the buildings are atoms. The cohesion and dynamics of these buildings are the result of interactions between these atoms. Two major classes of modeling techniques for these buildings can be distinguished: Electronic structure calculations and molecular simulation methods. Molecular simulation methods are limited in their application since they cannot be used to model properties that depend on the electronic structure. As part of the electronic structure calculations, the building is described by the notion of wave function. One of the fundamental tasks of quantum physics is to solve a differential equation according to the electronic, nuclear and spin coordinates via the Schrödinger equation. The resolution of this equation in analytical form is impossible, except in the case of hydrogenites. Different numerical resolution methods have been developed based on a series of simplifications and successive approximation techniques. Once solved, this equation gives the total energy of the system, the associated wave function, and the energies of the electronic states. These methods are applied at a temperature of zero and at a fixed pressure. There are several families of methods: Semi-empirical methods, Hartree-Fock (HF) methods and density functional (DFT) methods. From the dependence of the total energy on the volume of the mesh, we can deduce the equilibrium crystalline parameters, the modulus of rigidity or the enthalpy of formation. Finally and above all, they allow, through studies of electronic structure, to identify the phenomena that govern the substitutions. In other words, thanks to the fundamental laws of quantum physics, it is possible to compute macroscopic properties from microscopic information. The interface between the first-principle and experimental design could provide a way to answer a lot of problems and open questions on the physical properties of nanomaterials. The purpose of this book is to propose some ideas to answer the most important question in the design of nanomaterials (OD,1D and 2D) for nanotechnology application, namely, nanomaterials for spintronic application, nanomaterials for solar energy technologies application, magnetic refrigeration applications, switchable materials application and nanomedicine applications. Additionally, the author will discuss the correlation between the first-principle and experimental design to see how the properties of the yet-to-be-synthesized nanomaterials can be predicted. Based on experimental and on first-principle calculations design, the author will discuss structural, optical and magnetic properties of new nanomaterials. New physical properties will be discussed in nanomaterials recently observed, and this creates new opportunities for development and construction of a new nanomaterial for nanotechnology applications.

 Cellulose is the most important and naturally abundant organic biopolymer in the biosphere. It is the basic structural component of plant cell walls. Cellulose based materials have been utilized by our society as engineering materials for thousands of years and their use continues today as verified by the enormity of the worldwide industries. In recent decades, the conversion of renewable lignocellulosic biomass and natural biopolymers into chemicals, liquid fuels and feed supplements has gained considerable attention. In addition, the gradual depletion of petroleum resources, the lack of space for landfills, concerns over emissions during incineration, and environmental pollution caused due to accumulation of these non-destructible solid wastes has spurred efforts to develop high performance materials which are eco-friendly and sustainable. Keeping in mind the advantages of the bio-based materials from cellulose, this volume, edited by Tri-Dung (T.-D.) Ngo, includes cellulose from the micro- (cellulose fiber) to nanoscale (nanocellulose). This book focuses on the chemistry, production, properties and applications of the cellulose materials in various areas. From the view of sustainable development, the new materials associated with cellulose bio-renewable sources are enormously being addressed. In addition, nanotechnology is a rapidly evolving area of development, as science, engineering and technology have merged to bring nanoscale materials much closer to reality. The book also summarizes the recent developments made in the area of advanced bio-nanomaterials, chemical functionalization of celluloses from the micro- to nanoscale, and their processing and successful utilization for selected applications. A number of critical issues and suggestions for future work are discussed, underscoring the roles of researchers for the efficient development of advanced bio-nanomaterials through value addition to enhance their use.
