Book Description :

Nanomaterials hold great promise for applications in thermal management and thermoelectric power generation. Defects in these are important as they are generally inevitably introduced during fabrication or intentionally engineered to control the properties of the nanomaterials. Here, we investigate how phonon-contributed thermal conductance in narrow graphene, boron nitride (BN), and silicene nanoribbons (NRs), responds to the presence of a vacancy defect and the corresponding geometric distortion, from first principles using the non-equilibrium Green's function method. Analyses are made of the geometries, phonon conductance coefficients, and local densities of states (LDOS) of pristine and defected nanoribbons. It is found that hydrogen absences produce similar reductions in thermal conductance in planar graphene and BN NRs with greater reductions in buckled silicene NRs. Vacancies of larger atoms affect all systems similarly, causing greater reductions than hydrogen absences. Emerging flexible and stiff scattering centers, depending on bond strengths, are shown to cause thermal conductance reduction by changing nearby LDOSs in defected structures relative to pristine ones. This knowledge suggests that inferences on unknown thermal properties of novel defected materials can be made based on understanding how thermal transport behaves in their analogues and how bond characteristics differ between systems under consideration. The thermal conductance contributed by phonons is often a limiting factor to the overall suitability of a material for use in thermoelectric power generation, wherein a voltage is generated in a material by a temperature gradient. The thermoelectric figure of merit (ZT) assesses this suitability, in part based on a ratio of electrical conductance to thermal conductance. These two properties can be decoupled in low-dimensional structures like NRs, with lower thermal conductances generally found in narrower materials. Here, ZT is analyzed in graphene, BN, and silicene nanoribbons of two different widths with engineered edges that are designed to increase the ratio of edge length to NR length. This could conceivably be synthesized by either top-down or bottom-up methods. Analyses are made of how width and material change the maximum ZT attainable by controlling the chemical potential of each system, how these maximum ZTs differ in each system as a result of p- or n- type change to chemical potential, how full-width half-maximum values of ZT peaks behave, and how the different factors of ZT affect its final value in these systems. A very high ZT of 6.26 is reported near the bandgap in the narrow chevron silicene NR at room temperature, and a room temperature ZT greater than 3 is also found in the narrow BN NR, suggesting that edge-engineered NRs offer high promise for thermoelectric applications and may be suitable for emissions-free electricity generation from waste heat sources.

Book Description :

Thermal Transport in Carbon-Based Nanomaterials describes the thermal properties of various carbon nanomaterials and then examines their applications in thermal management and renewable energy. Carbon nanomaterials include: one-dimensional (1D) structures, like nanotubes; two-dimensional (2D) crystal lattice with only one-atom-thick planar sheets, like graphenes; composites based on carbon nanotube or graphene, and diamond nanowires and thin films. In the past two decades, rapid developments in the synthesis and processing of carbon-based nanomaterials have created a great desire among scientists to gain a greater understanding of thermal transport in these materials. Thermal properties in nanomaterials differ significantly from those in bulk materials because the characteristic length scales associated with the heat carriers, phonons, are comparable to the characteristic length. Carbon nanomaterials with high thermal conductivity can be applied in heat dissipation. This looks set to make a significant impact on human life and, with numerous commercial developments emerging, will become a major academic topic over the coming years. This authoritative and comprehensive book will be of great use to both the existing scientific community in this field, as well as for those who wish to enter it. Includes coverage of the most important and commonly adopted computational and experimental methods to analyze thermal properties in carbon nanomaterials Contains information about the growth of carbon nanomaterials, their thermal properties, and strategies to control thermal properties and applications, allowing readers to assess how to use each material most efficiently Offers a comprehensive overview of the theoretical background behind thermal transport in carbon nanomaterials

Book Description :

Covid-19 outbreak has been the biggest health, social and economic emergency the world has ever faced since the Second World War. The pandemic has drastically changed, at least temporarily, the way society, businesses, and infrastructure systems operate. It has forced us to take a closer look at our woefully inadequate health infrastructure. It also led to the closure of educational institutions and turned formal learning into distance learning, posing a daunting challenge of demand for e-learning infrastructure. Social distancing policies (SDPs), encouraging people to stay home and limit gatherings, impacted wide range of services and industries. The telecommunications infrastructure, in particular, became a spotlight in view of its critical importance to keep businesses, governments, and societies connected and running in the period of economic and social disruption. The governments acknowledged a fact that “telecommunications, internet services, broadcasting, cable services, IT and IT-enabled services (ITeS)” are the essential services. Work from Home (WFH) seemed a positive experience, however with some adverse impact on the social, behavioural and physical factors. ICEIM 2022 is a humble contribution of SPM PDEU in terms of presenting a scholarly platform wherein abundance of ideas, answers, right questions, and complementing new learning’s are expected to emerge. The conference aims at discussing and deliberating various contemporary issues and challenge in the management of energy & infrastructure. The conference showcases seven tracks, five of which are Business & Technology, Finance, Human Resource, Marketing, and Project & Operations Management. Then in view of emerging scenario, two more tracks were added namely, Business Analytics and Data Science, Strategies & Entrepreneurship Management. We do expect to receive 80–90 research papers covering various tracks of the conference. We have so far got regular research papers, industry papers, Ph.D. research papers and students’ research articles. New research directions also constitute an agenda of a conference. This conference had three plenary sessions: a) Emerging Electrical Vehicle Ecosystem: Prospects and Impediments, b) Infrastructure Development in India: Policy Perspectives and Innovative Financing Initiatives, c) Energy Sector Management: Challenges and Strategies in Industry 4.0 era. All the plenary sessions of this conference have speakers mostly from the industry. We strongly believe that this International Conference will provide ample opportunities to all participants to disseminate new research ideas with industry professionals as well as the policy-makers. It is also believed that this International Conference will initiate new thought process towards the issues and challenges faced by the energy and infrastructure and will definitely add substantially to the existing domain of knowledge. We are pleased to present this proceeding of the International Conference to the academicians, researchers, industry practitioners and policy-makers who all have joined hands towards building the new knowledge development in the area of energy & infrastructure management.

Book Description :

Understanding non-equilibrium properties of classical and quantum many-particle systems is one of the goals of contemporary statistical mechanics. Besides its own interest for the theoretical foundations of irreversible thermodynamics(e.g. of the Fourier's law of heat conduction), this topic is also relevant to develop innovative ideas for nanoscale thermal management with possible future applications to nanotechnologies and effective energetic resources. The first part of the volume (Chapters 1-6) describes the basic models, the phenomenology and the various theoretical approaches to understand heat transport in low-dimensional lattices (1D e 2D). The methods described will include equilibrium and nonequilibrium molecular dynamics simulations, hydrodynamic and kinetic approaches and the solution of stochastic models. The second part (Chapters 7-10) deals with applications to nano and microscale heat transfer, as for instance phononic transport in carbon-based nanomaterials, including the prominent case of nanotubes and graphene. Possible future developments on heat flow control and thermoelectric energy conversion will be outlined. This volume aims at being the first step for graduate students and researchers entering the field as well as a reference for the community of scientists that, from different backgrounds (theoretical physics, mathematics, material sciences and engineering), has grown in the recent years around those themes.

Book Description :

With the development of the scanning tunneling microscope, nanoscience became an important discipline. Single atoms could be manipulated in a controlled manner, and it became possible to change matter at its 'ultimate' level; it is the level on which the properties of matter emerge. This possibility enables to construct and to produce devices, materials, etc. with very small sizes and completely new properties. That opens up new perspectives for technology and is in particular relevant in connection with nano-engineering.Nanosystems are unimaginably small and very fast. No doubt, this is an important characteristic. But there is another feature, possibly more relevant, in connection with nanoscience and nanotechnology. The essential point here is that we work at the 'ultimate level'. This is the smallest level at which the properties of our world emerge, at which functional matter can exist. In particular, at this level biological individuality comes into existence. This situation can be expressed in absolute terms: This is not only the strongest material ever made, this is the strongest material it will ever be possible to make (D Ratner and M Ratner, Nanotechnology and Homeland Security). This is a very general statement. All aspects of matter are concerned here. Through the variation of the composition various forms of matter emerge with different items.Nanosystems are usually small, but they offer nevertheless the possibility to vary the structure of atomic (molecular) ensembles, creating a diversity of new material-specific properties. A large variety of experimental possibilities come into play and flexible theoretical tools are needed at the basic level. This is reflected in the different disciplines: In nanoscience and nanotechnology we have various directions: Materials science, functional nanomaterials, nanoparticles, food chemistry, medicine with brain research, quantum and molecular computing, bioinformatics, magnetic nanostructures, nano-optics, nano-electronics, etc.The properties of matter, which are involved within these nanodisciplines, are ultimate in character, i.e., their characteristic properties come into existence at this level. The book is organized in this respect.
