|Diverse Applications of Nanotechnology in Biomedicine, Chemistry, and Engineering
Shivani Soni, Amandeep Salhotra, Mrutyunjay Suar.
As a paradigm for the future, micro-scale technology seeks to fuse revolutionary concepts in science and engineering and then translate it into reality. Nanotechnology is an interdisciplinary field that aims to connect what is seen with the naked eye and what is unseen on the molecular level.
Quantum and Optical Dynamics of Matter for Nanotechnology
Mihai V. Putz.
With the emergence of nanoscience and technology in the 21st century, research has shifted its focus on the quantum and optical dynamical properties of matter such as atoms, molecules, and solids which are properly characterized in their dynamic state.

Nanotechnology: Concepts, Methodologies, Tools, and Applications
Information Resources Management Association.
Over the past few decades, devices and technologies have been significantly miniaturized from one generation to the next, providing far more potential in a much smaller package. The smallest of these recently developed tools are miniscule enough to be invisible to the naked eye.
Interacting Quantum Systems
In this chapter, basic quantum tools such as time-evolution operators, transition rates and amplitudes, statistical and projector operators, and interaction and density matrix representations are employed to characterize the open and interacting quantum systems with the aid of Schrödinger, quantum...
The Dynamics of Molecular Photo-Dissociation
Such quantum spectroscopy tools as absorption cross sections, autocorrelation functions, Fourier transformations, and Born-Oppenheimer approximations are employed for the phenomenological and analytical characterization of the molecular evolution under light interaction. Events such as...
The Fundamentals of Quantum Optical Transitions
Elementary and advanced concepts of quantum optics and spectroscopy are formulated, exemplified, and applied, and they relate the quantum states of a substance under electromagnetic action: from black-body radiation, to a spectral line profile’s characterization by widths and intensities, to solving...
Light Amplification Analysis
The main geometrical and quantum relationships between light and a substance are derived by characterizing the laser’s light generation, threshold, resonances, stability, multimode locking and selection, polarization and stimulated Raman phase matching towards achieving the best energy gain...
The Basics of Non-Linear Optics
At a semi-classical level, the main analytical electromagnetic field theory tools were first used to describe the non-linear effects of light-light coupling as a basic cause of nonlinear optical phenomena and applications.
Molecular Light Control in Rare-Gases Matrices: The HCl Case
Various characteristics and mechanisms of HCl that has been entrapped in rare gas matrices (Ar, Kr, and Xe) are presented with regard to the spectroscopic characterization of exciplexes, cage exits, photo-dissociations, charge transfers, and the harpoonic mechanism. In addition, this chapter sheds...
Raman Saturate Absorption
Remarkable atomic population difference symmetry and coherence properties that are achieved without the custom laser-induced population inversion by the non-linear (Raman) saturated absorption spectroscopy are quantum mechanically explained and analytically modeled.
Spectral Atomic Selection and Pumping
Basic concepts of modern quantum optics as of Ramsey-Raman-Rabi spectroscopy through pulses rather than by using a broad single light excitation of two-level atomic/molecular system towards atomic pumping, selection, and interferometer are exposed in an analytical and phenomenological manner.
Gravitational Influence on Atomic Interference
Two-level atomic systems are studied under gravitation influence and then employed in sequential pulse towards modeling the Kasevich-Chu interferometer with matter waves.
General Relativity Evolution of the Photons in Dielectrics
Basic Einstein general relativity equations are linearized and coupled with Maxwell electromagnetic field equations to produce local gravitationally corrected Minkowsky space metrics; fundamental application on gravity action of an intense laser beam upon a weaker parallel one in dielectrics is...
General Concepts and Theories in X-Ray Diffraction
The various forms of the X-Ray Diffraction (XRD) theory in the crystal are considered as perfect or imperfect for the version “perfect on portions” (i.e. with slight deformations or with a constant deformation gradient), following historical developments and performances of the models.
Classical and Quantum Theories of Dynamic X-Ray Diffraction
The main results of the dynamical theories of X-ray diffraction in their standard form of coupling of Maxwell equations with the Bloch waves on the one hand and the interaction of radiation-crystal in terms of perspective of quantum field on the other are unitarily presented.
The Concept of X-Ray Standing Wave
The concept of “Standing Waves” (SW) that arise in the crystal dynamically “attacked” by the frequency fields X is analytically analyzed towards expressing, in almost all the cases, the total intensity of the fields on dispersion branches in the perfect crystal and for the embedded layer on the...
Experimental Implications of X-Ray Standing Waves
Basic concepts of dynamic X-ray diffraction are applied in distinguishing between the propagation along the atomic planes characterized by the linear absorption coefficient and the perpendicular propagation on the atomic planes. Propagation is responsible for the generation of the standing waves...
Absorption Coefficients of Inelastic Dynamic X-Ray Diffraction
The X-ray inelastic scattering phenomena during the time-dependent perturbations are described with the aid of dynamical dispersion equations coupled with charge current in the Maxwell equations towards the appearance of the Debye-Waller factor driving the absorption coefficient, either for inelastic...

A Networking Paradigm Inspired by Cell Communication Mechanisms
This chapter provides a brief review of molecular communication, a networking paradigm inspired by cell communication mechanisms. In molecular communication, information is encoded to and decoded from molecules, rather than electrons or electromagnetic waves. Molecular communication provides...

Bionanotechnology is multidisciplinary knowledge gained at the intersection of biology and nanotechnology. Certainly, biology operates in the nanoscale regime, using natural processes that occur in the nanoscale, by convention, under 100 nm in dimension. Therefore, bionanotechnology relates to those...
Nanoroots of Quantum Chemistry: Atomic Radii, Periodic Behavior, and Bondons
Mihai V. Putz.
This chapter identifies specific roots of chemistry and quantum chemistry and advances the idea that length and energy carry major roles at the nano-quantum level. A detailed exposition of this binom is unfolded under the specific radii-electronegativity or radii-chemical hardness that is then...
Parallel Quantum Chemistry at the Crossroads
Hubertus J. J. van Dam.
Quantum chemistry was a compute intensive field from the beginning. It was also an early adopter of parallel computing, and hence, has more than twenty years of experience with parallelism. However, recently parallel computing has seen dramatic changes, such as the rise of multi-core architectures...
