Introduction To Heterogeneous Catalysis
Catalysis is a multidisciplinary subject. This book introduces the chemical, materials, and engineering principles of catalysis so that both MSc and PhD students with a basic but not extensive knowledge of chemistry and physics and those with a basic understanding of chemical engineering can learn more about catalysis.Examples are taken from catalytic reactions and catalysts used in the energy, petroleum, and base-chemicals industry.The second edition differs from the first edition in the way basic topics are integrated with catalytic applications.The authors introduce two new chapters: 'Cleaning of Fuels by Hydrotreating' and 'Electrocatalysis'.Hydrotreating is a very important industrial process and offers the opportunity to discuss metal sulfide catalysts.Electrocatalysis gains more and more attention because it can be used to minimize the anthropogenic COâ‚‚ emissions.Solar, wind, and hydroelectricity can drive water electrolysis and COâ‚‚ electroreduction and, therefore, excess renewable electricity can be stored in chemicals.Introduction to Heterogeneous Catalysis (Second Edition) is intended for a one-semester course for master and PhD students who want to learn more about the principles of catalysis.This must-read textbook will enable students to read catalysis literature without much difficulty and presents not only the basic concepts of catalysis but integrates the chemical, materials, and engineering aspects of catalysis with industry examples.

Ultra-Dense Heterogeneous Networks
Driven by the ever-increasing amount of mobile data, cellular networks evolve from small cell network to ultra-dense heterogeneous networks, to provide high system capacity and spectrum efficiency.By bringing base stations (BSs) to the approximate spatial scale and number magnitude, ultra-dense heterogeneous networks would definitely bring unprecedented paradigm changes to the network design.Firstly, along with densification of small cells, inter-cell interference becomes severe and may deteriorate performance of mobile users.Assigning network resources including bandwidth and time slots, while avoiding interference, desires serious consideration.Secondly, the coverage area of BSs becomes small and irregular, resulting in much frequent and complicated handovers when mobile users move around.How to ensure continuous communication and implement effective mobility management, and inter-cell resource allocation and cooperation, remains a challenging issue.Thirdly, such dynamic change in spatial dimension enables us to re-investigate available and ongoing communications and networking techniques, such as massive MIMO, CoMP, millimeter waves (mmWaves), carrier aggregation, full duplex radio, and D2D communications. To address the aforementioned challenging research issues, this book will investigate the service and QoE provisioning in ultra-dense heterogeneous networks.In particular, firstly we introduce ultra-dense heterogeneous networks by careful definition regarding spatial deployment, generic characteristics, and requirements of ultra-dense heterogeneous networks in order to ensure QoE of mobile users.Secondly, we depict the resource management among small cells in close proximity, mobility management for mobile users (address the super-frequent handovers), and interference management (dealing with the interference due to frequency-reuse in the vicinity).Thirdly, we study the enabling factors, and the integration of ultra-dense heterogeneous networks with enabling technologies, such as massive-MIMO, cloud-RAN, mmWaves, D2D, IoT.Finally, we conclude the book and indicate future directions and challenges.

What are heterogeneous and homogeneous mixtures in chemistry?
In chemistry, a heterogeneous mixture is a combination of two or more substances that are visibly distinguishable from each other. This means that the components of a heterogeneous mixture do not blend uniformly and can be easily separated. On the other hand, a homogeneous mixture is a combination of substances that are evenly distributed throughout the mixture, resulting in a uniform composition. This makes it difficult to distinguish the individual components of a homogeneous mixture.

What are homogeneous and heterogeneous mixtures in chemistry?
Homogeneous mixtures are uniform in composition, meaning that the components are evenly distributed throughout the mixture. Examples of homogeneous mixtures include saltwater and air. Heterogeneous mixtures, on the other hand, are not uniform in composition and contain visibly different substances. Examples of heterogeneous mixtures include a salad with different vegetables and a mixture of oil and water.

Is mayonnaise heterogeneous?
Yes, mayonnaise is considered heterogeneous because it is a mixture of different substances that do not fully blend together. It is made up of oil, eggs, vinegar, and other ingredients that do not fully dissolve or mix uniformly, resulting in a non-uniform appearance and texture. This makes mayonnaise an example of a heterogeneous mixture.

What is heterogeneous development?
Heterogeneous development refers to the uneven progress or growth that occurs within a particular region or country. It means that different areas or groups within the same region experience varying levels of development, resulting in disparities in terms of income, infrastructure, education, and other socio-economic indicators. This can be due to factors such as unequal distribution of resources, historical legacies, government policies, or global economic trends. Addressing heterogeneous development often requires targeted interventions and policies to reduce disparities and promote more inclusive growth.

Why is milk heterogeneous?
Milk is heterogeneous because it is a mixture of different substances that do not fully blend together. It contains water, proteins, fats, lactose, vitamins, and minerals, all of which have different properties and do not form a uniform solution. When left to stand, milk will separate into layers, with the cream rising to the top and the denser liquid settling at the bottom, further demonstrating its heterogeneity.

What is the difference between heterogeneous and homogeneous in chemistry?
In chemistry, heterogeneous mixtures are made up of different substances that are physically distinct and can be easily separated, such as a mixture of oil and water. On the other hand, homogeneous mixtures are uniform throughout and have the same composition and properties in all parts, like salt dissolved in water. Essentially, heterogeneous mixtures have visible boundaries between the different components, while homogeneous mixtures appear the same throughout.
-
Is steel homogeneous or heterogeneous?
Steel is considered to be a homogeneous material. This is because steel is a solid solution of iron and carbon atoms, where the atoms are uniformly distributed throughout the material. This uniform distribution gives steel consistent properties and characteristics throughout its structure, making it a homogeneous material.
