Preparation of Cu-Sn-S Thin Films for Solar Cell Application
The most popular polycrystalline thin film solar cells such as CdTe and Cu(In, Ga)Se2 showed high photovoltaic conversion efficiencies of 22.1% and 22.6%, respectively. However, the aforementioned absorber layers contain scarce (In, Ga, Se, and Te) and highly toxic (Cd, Se, and Te) elements which limit their future prospects. Due to this, researchers developed a new and promising absorber material, Cu2ZnSnS4 (CZTS), but the deposition of single-phase CZTS thin films is difficult due to its complex structure. In addition, suppression and detection of secondary phases (Cu-S, Zn-S, Sn-S, and Cu-Sn-S) in CZTS thin films are critical challenges. To solve this problem, growth on an alternative absorber layer is needed for the preparation of solar cells. Keeping the above research areas in mind, we conducted considerable research on the preparation of Cu-Sn-S layers using a two-stage process, characterization and tuning the structural, optical, and electrical properties of the Cu2SnS3 layers. More importantly, XRD, Raman, EDAX, SIMS, SEM, AFM, UV-Vis-NIR spectrophotometer, and Hall Effect characterizations revealed the suitability of Monoclinic Cu2SnS3 for solar cell device application.
Generation IV International Forum (Gif)
Effective and practical solutions, for the repeated nuclear accidents and for the existing and expected inventories of highly active long-lived radioactive waste, are urgently needed to have a reliable, sustainable and safe nuclear source of energy. Generation IV International Forum (GIF) was established in 2001 to find promising solution for the problems encountered in nuclear power industry. Eight goals have been defined for Generation IV systems in four broad areas: sustainability, economics, safety and reliability, and proliferation resistance and physical protection. The GIF has selected six reactor technologies that are supposed to fulfil the requirement of the GIF goals for further research and development. Unfortunately, the choice of the six nuclear power technologies by Generation IV International Forum (GIF) took in consideration the benefits, experiences and interest of each country and the difficulties encountered in moving the developing applications technology outside of current Nuclear Power Plants (NPPs) more than considering the importance of meetings the requirements of the essential goals proposed by the GIF countries them self.
Astronomy & Astrophysics
The present text was probably at least 35 years in the making, preparation. The astronomy and astrophysics content and problems appearing were collected from a number of basic and advanced astronomy and astrophysics courses and technical workshops at the Harry Bayley Observatory in Barbados from 1977- 1989. Other content emerged from an extended series of articles written under the banner of 'Mathematics in Astronomy' for The Journal of the Barbados Astronomical Society over 1977 - 1990. The content is of varying difficulty and ranges from simple astronomy problems to do with sidereal time, stellar magnitudes and Kepler's planetary laws to spherical astronomy, including using matrices for coordinate transformations, and stellar evolution-structure, solar physics and galactic dynamics. It will be no surprise that some topics (and their related problems) will be fairly easy to master while others (e.g. Solar MHD, galactic structure, special relativity) will be much more difficult. Still, I hope more adventurous readers will at least attempt the problems in the latter chapters. An optics supplement is also included as well as a primer on differential equations, which are really the "skeleton key" to doing any advanced physics, astrophysics.
Saharan Winds
As the climate crisis ensues, a transition away from fossil fuels becomes urgent. However, some renewable energy developments are propagating injustices such as landgrabs, colonial dispossession, and environmentally destructive practices. Changing the way we imagine and understand wind will help us ensure a globally just wind energy future. Saharan Winds contributes to a fairer energy horizon by illuminating the role of imaginaries-how we understand energy sources such as wind and the meanings we attach to wind-in determining the wider politics, whether oppressive or just, associated with energy systems. This book turns to various cultures and communities across different time periods in Western Sahara to explore how wind imaginaries affect the development, management, and promotion of wind farms; the distribution of energy that wind farms produce; and, vitally, the type of politics mediated by all these elements combined. Highlighting the wind-fueled oppression of colonial energy systems, the book shows the potential offered by nomadic, Indigenous wind imaginaries for contributing to a fairer energy future.
Theoretical study of semiconductor materials
This book is a theoretical study that presents a little of the history of atomism, from the first idea of the atom in ancient Greece to Bohr's model, which is not the current model but has played an important role in understanding the microscopic world. Based on Bohr's model, we present semiconductor materials and their particularities, which, thanks to knowledge of energy levels, can be worked on to better serve certain purposes. Semiconductor materials are the basis of technological advances in society. Knowledge of the electronics of these materials, which has come about through the evolution of physics, has led to improvements in people's daily lives. By getting to know the physics behind the technologies, not just this physics, it is possible to answer the questions asked by the students and give meaning to the content, to show that physics has applications and meaning for humanity, to show that they use the physics taught in the classroom every day, whether using their mobile phones, television, taking a bath in a hot shower, using electrical and electronic equipment, to show that this equipment has evolved substantially thanks to the evolution of physics.

The birth of the universe from nothing
Where does our universe come from? Can the universe create itself? Why is there something instead of nothing? Does a universe born out of nothing exclude God?The birth of the universe has become, in recent decades, one of the central themes of scientific research. Physicists and philosophers have hypothesized the birth of the universe starting from the so-called "quantum vacuum". But it is not enough. In this volume we demonstrate how a universe can spontaneously create itself from nothing.
Alien Physics
A report on apparent subliminal communication by intelligent Aliens who wish to help us advance our theoretical understanding of nature and the universe. Seemingly unable to communicate with or guide us directly, they've studied all our doctrinal and alternative theories and pointed to those consistent with their own far more advanced understanding. The many inconsistencies and anomalies in our current physics are resolved, often needing fundamental review of long held beliefs. The guidance is heuristic not mathematical, has proved empirically fully consistent and is far easier to understand then much terrestrial Physics theory. The subjects explained include all major fundamental areas including what we categorize as Relativity & Quantum Mechanics (causally unified), Logic, Dark Matter & Energy, Gravity, Cyclic Galaxy Evolution and Cosmology.
Cryogenic Heat Management
Cryogenic engineering (cryogenics) is the production, preservation, and use or application of cold. This book presents a comprehensive introduction to designing systems to deal with heat - effective management of cold, exploring the directing (or redirecting), promoting, or inhibiting this flow of heat in a practical way. It provides a description of the necessary theory, design methodology, and advanced demonstrations (thermodynamics, heat transfer, thermal insulation, fluid mechanics) for many frequently occurring situations in low-temperature apparatus. This includes systems that are widely used such as superconducting magnets for magnetic resonance imaging (MRI), high-energy physics, fusion, tokamak and free electron laser systems, space launch and exploration, and energy and transportation use of liquid hydrogen, as well as potential future applications of cryo-life sciences and chemical industries. The book is written with the assumption that the reader has an undergraduate understanding of thermodynamics, heat transfer, and fluid mechanics, in addition to the mechanics of materials, material science, and physical chemistry. Cryogenic Heat Management: Technology and Applications for Science and Industry will be a valuable guide for those researching, teaching, or working with low-temperature or cryogenic systems, in addition to postgraduates studying the topic.Key features: Presents simplified but useful and practical equations that can be applied in estimating performance and design of energy-efficient systems in low-temperature systems or cryogenics Contains practical approaches and advanced design materials for insulation, shields/anchors, cryogen vessels/pipes, calorimeters, cryogenic heat switches, cryostats, current leads, and RF couplers Provides a comprehensive introduction to the necessary theory and models needed for solutions to common difficulties and illustrates the engineering examples with more than 300 figures
Ferromagnetic Resonance in Orientational Transition Conditions

One Hundred Phy Visual..(2nd Ed)
This volume is now more than a decade old, and much has transpired since then. The MATLAB tools have evolved from scripts, to Apps and at present to Live code. The Live package is preferred because it combines text and equations with MATLAB code all in a single site. The results of that code, formerly shown separately, also appear in line and in this way the user can vary the parameters of the specific problem and explore immediately how the solutions vary in response. For this reason, the Live scheme is used exclusively in this edition.The physics landscape has also evolved in the last decade. The Nobel prize in 2006 rewarded the discovery of small perturbation in temperature, at the parts per million level of the extreme isotropy of the Cosmic Microwave Background (CMB). The basic isotropy is now thought to indicate a period of rapid expansion of the Universe, called 'inflation'. With those discoveries, there has been more emphasis on astrophysics and cosmology, which contributes to advances in physics over the last decade. These changes have been reflected in the problems which are explored in this volume.
Elementary Particles and the Early Universe
This book is suitable for those taking courses on particle physics, general relativity, and cosmology.

Order, Disorder and Criticality: Advanced Problems of Phase Transitions and Complex Systems - Volume 8
This book is the eighth volume of review chapters on advanced problems of phase transitions and critical phenomena in complex systems. The aim of the book is to provide reviews in those aspects of criticality and related subjects that attract currently much attention due to essential new contributions. The current volume consists of five chapters. They discuss various aspects of studies in the field of critical phenomena as well as criticality of complex systems, where the new, emergent properties appear via collective behaviour of simple elements. Since all complex systems involve cooperative behaviour between many interconnected components, the field of phase transitions and critical phenomena provides a very natural conceptual and methodological framework for their study. As with the first seven volumes, this book is based on the review lectures that were given in Lviv (Ukraine) at the 'Ising lectures' -- a traditional annual workshop on complex systems, phase transitions and critical phenomena which aims to bring together experts in these fields with university students and those who are interested in the subject.
The First Adventures on Differential Geometry
This book serves as a friendly stepping stone for readers who wish to start learning differential geometry. It lays down the most essential foundations, ensuring that readers feel prepared to tackle more advanced concepts in the future. Differential geometry is often perceived or presented as a myriad of seemingly disjointed ideas to beginners. This book bridges those gaps by following the story of a character named Beng, along with his friends, as they journey to master differential geometry. Starting with the basics in Euclidean space, the book offers an accessible entry point into understanding geometry. It then progresses to curved surfaces and intrinsic geometry, culminating in a quintessential application of Ricci curvature. Readers will explore the Einstein equation and work through the Schwarzschild solution, ultimately calculating the event horizon for a non-rotating black hole.The exercises throughout the book are crafted to develop a deep understanding of the subject, with detailed solutions provided to guide readers through each step. Based on a series of lecture notes from a course designed for a broad audience, this book has been classroom-tested, proving its effectiveness as an introductory and illuminating textbook.

God's Signature in the Stars, Volume One
Are there credible reasons to believe many of the constellation and star names were given by inspiration of God? God's Signature in the Stars explores these ancient star names and their meanings to reveal the answer. The Bible states that God named the stars: "He who brings out the starry host one by one and calls forth each of them by name" (Isa 40:26). These starry hosts appear in the night sky as God's "character actors," performing their roles on his celestial stage. God is the creator, writer, and director of this heavenly drama and cosmic dance. "By day and by night," his "starry hosts" are flickering above the footlights in God's theater in the sky!
Cometary Impacts on Jovian Magnetosphere
From the stand point of basic physical phenomena, Jupiter is considered as the most interesting of the planets. On the basis of radio evidence, it has an immense radiation belt of relativistic electrons and a magnetic moment more than 105 times that of the Earth. The Jupiter's magnetosphere is highly unlike the Earth's in its fundamental workings. The difference challenges our thought and understanding of magnetospheric physics and the behavior of matter on a cosmic scale. The Earth's magnetosphere extracts essentially all of its energy and some significant fraction of its plasma from the solar wind while on the other hand Jupiter's magnetosphere is powered by the slowing of Jupiter's spin and in fact approximately all of its magnetospheric plasma originates from the internal sources; mainly from the satellite-Io and the Jovian ionosphere. Besides, Jupiter exhibits weak but genuine pulsar behavior. Jupiter functions unlike other magnetosphere and allows stretching our conceptions for developing better theories of the Earth's magnetosphere. It also links to distant astrophysical objects for gathering information about them in various forms of remote sensing.

Negative numbers do not exist. There are only positive lengths in different directions. Humans will simply turn a ruler into the opposite direction, if they pretent to measure a negative quantity. But all these quantities still are positive, of course. Negative numbers do not exist. But intelligent starfishes exist. Intelligent starfishes describe their mathematical world by using the three directions of their tentacle arms. And these three directions are equivalent and positive, of course. In this book intelligent starfishes describe the Special Relativity of Einstein. This description is based on their mathematics of three directions, which is the mathematics of a relativistic spacetime plane. These three directions are: the direction of time, the direction of space, and the direction of light, of course. Aeons ago, ages still will come and go, a young, shy, wise, and very, very far-sighted starfish scientist roamed through the bizarre Gog Magog underwater hills, climbed an underwater tree and invented the Dirac algebra of starfishes. By using this Dirac algebra of starfishes relativistic time dilation, length contraction, and Lorentz transformations are explained. And this mathematics is that simple and easy that readers will not have to struggle with the physics. They only have to struggle with the text, because ... sdrawkcab nettirw si tI.

Classical Mechanics and Electrodynamics (Second Edition)
The book gives a general introduction to classical theoretical physics, in the fields of mechanics, relativity and electromagnetism. It is analytical in approach and detailed in the derivations of physical consequences from the fundamental principles in each of the fields. This second edition has a new part, namely Classical Field Theory. Highlighting a close connection between this part and earlier parts of the book, where particles, rather than fields are the center of attention.As a general introduction to classical theoretical physics, the book is different from most textbooks at this level, which focus either on classical mechanics or classical electrodynamics but not both. The book will in particular be useful as a textbook for physics courses with such a broader approach to classical physics. For a wider group of students, the book may be of interest for self study. The new inclusion on classical field theory, will give students greater understanding on previous parts of the book, such as examining the Lagrangian formulation of Maxwell's equations with Noether's theorem. This is central in the use of Lagrangian on fields, as also discussed.The text is illustrated with many figures, most of these in color. There are many useful examples and exercises which complement the derivations in the text.

Optimality of The Evolution of The Universe, The Big Bang Model
The connection between matter located in the physical microcosm and in the Universe is noted. Galaxies are presented in the form of galaxy particles. The expansion and contraction of the Universe is modeled as a process of concentration of galaxy particles. The stable and unstable system of Lotka-Voltaire equations is used as models for the expansion and contraction of the sphere of the Universe. It is shown that the equation modeling the behavior of galaxy particles satisfies the Euler-Lagrange optimization equation. It is shown that an imaginary ball of the Universe passes through a narrow region of the pseudosphere-coil and thereby causes the Big Bang. Some differential geometry models used to simulate the Big Bang are presented. It is said that, in a generalized sense, this monograph completes the work of A.A. Friedman to its logical conclusion.
