Within a decade, MAX phase borides have drawn interest in research owing to their enhanced thermal and mechanical properties. In this work, we present a comprehensive study of the stability and structural, electronic, mechanical, and optical properties of Y 2 AB (A = Ga, In) boride MAX phases. The density functional theory (DFT) is used to investigate and analyze the properties of these compounds. Chemical stability is predicted by calculating the formation energy, while mechanical stability is confirmed through the stiffness constant C ij . The electronic band structure confirms the material’s metallic nature and anisotropic behavior, while the density of states (DOS) reveals the covalent chemical bonding within the compounds. To understand the mechanical behavior of this compound, elastic moduli, bulk modulus, shear modulus, and Vickers hardness have been investigated. According to Poisson’s ratio and Pugh’s ratio, Y 2 AB (A = Ga, In) are predicted as a ductile material. In addition, optical properties such as reflectivity ( R ), refractive index ( n ), absorption coefficient ( α ), extinction coefficient ( k ), photoconductivity ( σ ), and loss function (LF) have been studied for possible applications of the compounds to optical systems. These findings indicate that Y 2 GaB and Y 2 InB have potential use in UV-protective coatings, sensors, photodetectors, medical sterilization systems, and optical coating applications.

Petroleum and natural gas still remain the single biggest resource for energy on earth. Even as alternative and renewable sources are developed, petroleum and natural gas continue to be, by far, the most used and, if engineered properly, the most cost-effective and efficient, source of energy on the planet. Drilling engineering is one of the most important links in the energy chain, being, after all, the science of getting the resources out of the ground for processing. Without drilling engineering, there would be no gasoline, jet fuel, and the myriad of other \"have to have\" products that people use all over the world every day. Following up on their previous books, also available from Wiley-Scrivener, the authors, two of the most well-respected, prolific, and progressive drilling engineers in the industry, offer this groundbreaking volume. They cover the basics tenets of drilling engineering, the most common problems that the drilling engineer faces day to day, and cutting-edge new technology and processes through their unique lens.

In this paper, based on recent research on BaTiO 3 (BT) nanoparticles, BT/P(VDF-HFP) nanocomposites, frequency-dependent dielectric properties of such a material system with high energy density have been investigated as functions of the volume fraction of the nanoparticles at room temperature by several theoretical models. For single domain and single crystals of BT, a Debye type of dissipation and soft mode theory have been adopted to obtain a more precise frequency-dependent dielectric spectrum of BT. For nanodielectric composites, among the others, Wiener Rule, Lichtenecker model, Maxwell–Wagner model, Yamada, and modified Kerner model were applied to evaluate the frequency-dependent dielectric spectrum of nanocomposites. A simple rule of mixture for the dielectric loss tangent was obtained using Lichtenecker logarithmic rule. The results from theoretical calculations are compared with the experimental data. For the dielectric constant, Lichtenecker model, Maxwell–Wagner model, and Yamada model show reasonable agreements with the experimental data up to 50 % volume fraction of the nanoparticles. At the higher volume fraction of the nanoparticles, the experimental data show a decreasing trend of the dielectric constant of the composites due to an increase in porosity of the system. In this case, a three-phase model (nanoparticles/pores/matrix) was developed to predict dielectric properties of the system at higher volume fraction of the nanoparticles (up to 80 %). The results showed reasonable agreements for a wide range of frequency. This theoretical study provides an essential information on dielectric properties of polymer-based BT nanocomposites with a wide frequency range instead of the trial-and-error strategy of experiments and can be used for designing high energy density dielectric materials in the future.

Petroleum and natural gas still remain the single biggest resource for energy on earth. Even as alternative and renewable sources are developed, petroleum and natural gas continue to be, by far, the most used and, if engineering properly, the most cost-effective and efficient, source of energy on the planet. Contrary to some beliefs, the industry can, in fact, be sustainable, from an environmental, economic, and resource perspective. Petroleum and natural gas are, after all, natural sources of energy and do not have to be treated as pariahs. This groundbreaking new text describes hydrocarbons in basement formations, how they can be characterized and engineered, and how they can be engineered properly, to best achieve sustainability. Covering the basic theories and the underlying scientific concepts, the authors then go on to explain the best practices and new technologies and processes for utilizing basement formations for the petroleum and natural gas industries.

First the frequency-dependent dielectric spectrum of a self-assembled pure BaTiO3 (BTO) nanocrystalline thin film with consideration of the packing density is studied using the Lichtenecker logarithmic rule and the modified Kerner model. Then the Wiener lower bound is modified to evaluate the overall effective dielectric properties for 2–2 type of layered nanocomposites within a large frequency range, and a simple rule of mixture is found to be suitable for predicting the dielectric permittivity of multi-layered composites. The calculated dielectric properties of the BTO/parylene nanocomposites agree reasonably well with the experimental data, whereas a little discrepancy in the dielectric loss tangent is shown in the frequency range beyond 105Hz.

This Second Edition of the original volume adds significant new innovations for revolutionizing the processes and methods used in petroleum reservoir simulations. With the advent of shale drilling, hydraulic fracturing, and underbalanced drilling has come a virtual renaissance of scientific methodologies in the oil and gas industry.This book clarifies the underlying mathematics and physics behind reservoir simulation and makes it easy to have a range of simulation results along with their respective probability. This makes the risk analysis based on knowledge rather than guess work. The book offers by far the strongest tool for engineers and managers to back up reservoir simulation predictions with real science. The book adds transparency and ease to the process of reservoir simulation in way never witnessed before. Finally, No other book provides readers complete access to the 3D, 3-phase reservoir simulation software that is available with this text.

Magnesium alloys have received a considerable research focus in transportation sector due to its lightness and environmental legislation to reduce green-house effects. In this work, a magnesium alloy containing aluminium, zinc and tin as major alloying addition was studied. After casting, the alloy was homogenised and hot-rolled at 400 °C. This temperature was sufficient to promote extensive dynamic recrystallization as evident from microstructure. Texture was obtained as pole figures. The pole figures clearly revealed basal texture which also ensures the rotating of the crystals along the rolling directions. Aging of the alloy was conducted up to 30 hr at 170 °C. Surprisingly, this T5 treatment showed increased mechanical properties with time. This behaviour was studied in scanning electron microscopy. It was found that spherical-shaped Mg2Sn particles were precipitated as both nano-size particles and micron-size particles. These particles were responsible to age-strengthening of the alloy. Since particle stimulated nucleation is size dependent phenomenon, only Mg17Al12 phase effectively participated in grain refining. Aging response was entirely due to the presence and coarsening of Mg2Sn particles.
