Emissions Control Catalysis
The important advances achieved over the past years in all technological directions (industry, energy, and health) contributing to human well-being are unfortunately, in many cases, accompanied by a threat to the environment, with photochemical smog, stratospheric ozone depletion, acid rain, global warming, and finally climate change being the most well-known major issues. These are the results of a variety of pollutants emitted through these human activities. The indications show that we are already at a tipping point that might lead to non-linear and sudden environmental change on a global scale. Aiming to tackle these adverse effects in an attempt to mitigate any damage that has already occurred and to ensure that we are heading toward a cleaner (green) and sustainable future, scientists around the world are developing tools and techniques to understand, monitor, protect, and improve the environment. Emissions control catalysis is continuously advancing, providing novel, multifunctional, and optimally promoted using a variety of methods, nano-structured catalytic materials, and strategies (e.g., energy chemicals recycling, cyclic economy) that enable us to effectively control emissions, either of mobile or stationary sources, improving the quality of air (outdoor and indoor) and water and the energy economy. Representative cases include the abatement and/or recycling of CO2, CO, NOx, N2O, NH3, CH4, higher hydrocarbons, volatile organic compounds (VOCs), particulate matter, and specific industrial emissions (e.g., SOx, H2S, dioxins aromatics, and biogas). The "Emissions Control Catalysis" Special Issue has succeeded in collecting 22 high-quality contributions, included in this MDPI open access book, covering recent research progress in a variety of fields relevant to the above topics and/or applications, mainly on: (i) NOx catalytic reduction from cars (i.e., TWC) and industry (SCR) emissions; (ii) CO, CH4, and other hydrocarbons removal, and (iii) CO2 capture/recirculation combining emissions control with added-value chemicals production.

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 CO2 emissions.Solar, wind, and hydroelectricity can drive water electrolysis and CO2 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.

How can catalysis be presented in a presentation?
Catalysis can be presented in a presentation by first explaining the concept of catalysis and its importance in various chemical reactions. This can be followed by examples of catalytic processes in industry and everyday life, such as the catalytic converters in cars or the use of enzymes in biological systems. Additionally, the different types of catalysts and their mechanisms can be discussed to provide a comprehensive understanding of catalysis. Visual aids such as diagrams, charts, and videos can also be used to illustrate the concepts and make the presentation more engaging.

Which kitchen appliances have a long lifespan, such as mixers, etc.?
Kitchen appliances that typically have a long lifespan include mixers, food processors, and high-quality blenders. These appliances are built to withstand frequent use and are often made with durable materials that can last for many years. Investing in well-known brands and models known for their longevity can also help ensure that these appliances have a longer lifespan. Regular maintenance and proper care, such as cleaning and storage, can also contribute to extending the lifespan of these kitchen appliances.

What is the difference between homogeneous and heterogeneous catalysis?
Homogeneous catalysis involves a catalyst that is in the same phase as the reactants, meaning they are all in the same state of matter (e.g. all in liquid phase). Heterogeneous catalysis, on the other hand, involves a catalyst that is in a different phase from the reactants, such as a solid catalyst in a liquid or gaseous reactant. Homogeneous catalysis typically allows for better control over the reaction conditions and selectivity, while heterogeneous catalysis often offers easier catalyst separation and recycling.

Which kitchen appliances also have a long lifespan, such as mixers, etc.?
Kitchen appliances such as mixers, blenders, and food processors are known for their long lifespan. These appliances are designed to withstand heavy use and are built with durable materials, making them reliable for many years. Additionally, high-quality brands and models of these appliances are often built to last, making them a worthwhile investment for any kitchen. Regular maintenance and proper care can also help extend the lifespan of these appliances.

Can someone explain the cycle of enzyme catalysis to me?
Enzyme catalysis involves a cycle of events that begins with the substrate binding to the active site of the enzyme. This binding induces a conformational change in the enzyme, bringing the active site into optimal position for catalysis. The enzyme then facilitates the conversion of the substrate into the product through the lowering of activation energy. Once the product is formed, it is released from the active site, allowing the enzyme to return to its original conformation and be available for another round of catalysis. This cycle of substrate binding, catalysis, and product release is repeated continuously as long as there are substrates available for the enzyme to act upon.
