Sorption - From Fundamentals to Applications
G.Z. Kyzas (Ed.)
pp. 1-151, Year: 2022
ISBN 978-1-80355-970-4, InTech - open science, Rijeka, Croatia
Sorption: From Fundamentals to Applications describes many points in sorption technique. Sorption is a physical and chemical process by which one substance becomes attached to another. Specific cases of sorption are treated as: (i) Absorption – “the incorporation of a substance in one state into another of a different state” (e.g., liquids being absorbed by a solid or gases being absorbed by a liquid); (ii) Adsorption – the physical adherence or bonding of ions and molecules onto the surface of another phase (e.g., reagents adsorbed to a solid catalyst surface); (iii) Ion exchange – an exchange of ions between two electrolytes or between an electrolyte solution and a complex. At the beginning of the 21st century, separation processes presented a comprehensive application of the major operations performed by various industries, such as chemical, food, environmental, and biotechnology. Sorption, one of the preferred separation processes because of its effectiveness at different interfaces, has caught the attention of many scientists.

Composite Nanoadsorbents
G.Z. Kyzas, A.C. Mitropoulos (Eds.)
pp. 1-386, Year: 2019
ISBN 978-0-12-814132-8, Elsevier, Oxford, UK
One of the most recent trends in environmental technology is the research turn to adsorbent materials. It is general accepted that one of the most promising techniques for wastewaters treatment is adsorption. There is a novel concept nowadays, which promotes the use of nanomaterials with the lowest possible cost. The most important aspect of nanomaterial is their special properties associated with nanoscale geometries. The most fundamental characteristic of nanomaterial is the high surface area to volume ratio, which results in a number of unusual physical and chemical properties, but another unique property of nanomaterial and recently most studied is the quantum size effect that leads to their discrete electronic band structure like those of molecules. The present Book “Composite Nanoadsorbents” includes recent progress of selected nanomaterials combining two major classes of recent science: (i) adsorption and (ii) nanotechnology. Two categories of pollutants are majorly discussed are: (i) dyes and (ii) heavy metals.

Granularity in Materials Science
G.Z. Kyzas, A.C. Mitropoulos (Eds.)
pp. 1-84, Year: 2018
ISBN 978-1-78984-308-8, InTech - open science, Rijeka, Croatia
The present Book “Granularity in Materials Science” describes many points in granularity of materials. Granular materials are very simple: they are large conglomerations of discrete macroscopic particles. If they are non-cohesive, then the forces between them are essentially only repulsive so that the shape of the material is determined by external boundaries and gravity. Yet despite this seeming simplicity, granular materials behave differently from any of the other standard and familiar forms of matter: solids, liquids or gases, and should therefore be considered an additional state of matter in its own right. We will see that at the root of this unique status are three important aspects: the existence of static friction, the fact that temperature is effectively zero and, for moving grains, the inelastic nature of their collisions. No one can seriously doubt that granular materials, of which sand is but one example, are ubiquitous in our daily lives. They play an important role in many of our industries, such as mining, agriculture, civil engineering and pharmaceutical manufacturing.

Novel nanomaterials: Synthesis and applications
G.Z. Kyzas, A.C. Mitropoulos (Eds.)
pp. 1-357, Year: 2018
ISBN 978-1-78923-089-5, InTech - open science, Rijeka, Croatia
The present Book “Novel nanomaterials: Synthesis and Applications” describes many points in materials of nanotechnology. Nanomaterials is one of the hottest fields in nanotechnology that studies fabrication, characterization, and analysis of materials with morphological features on the nanoscale in at least one dimension. Recent progress in synthesis and fundamental understanding of properties of nanomaterial has led to significant advancement of nanomaterial-based gas/chemical/biological sensors. The most important aspect of nanomaterial is their special properties associated with nanoscale geometries. The most fundamental characteristic of nanomaterial is the high surface area to volume ratio, which results in a number of unusual physical and chemical properties such as high molecular adsorption, large surface tension force, enhanced chemical and biological activities, and extreme mechanical strength, but another unique property of nanomaterial and recently most studied is the quantum size effect that leads to their discrete electronic band structure like those of molecules.

Kinetic Theory
G.Z. Kyzas, A.C. Mitropoulos (Eds.)
pp. 1-138, Year: 2017
ISBN 978-953-51-3801-3, InTech - open science, Rijeka, Croatia
The present Book “Kinetic theories” describes many theories in kinetics. The world is governed by motions. The term kinetics is partially originated from the Greek word “kinisis” which means motion. How important is motion in our life is easily understood. The kinetic theory describes a gas as a large number of submicroscopic particles (atoms or molecules), all of which are in constant rapid motion that has randomness arising from their many collisions with each other and with the walls of the container. Kinetic theory explains macroscopic properties of gases, such as pressure, temperature, viscosity, thermal conductivity, and volume, by considering their molecular composition and motion. The theory posits that gas pressure is due to the impacts, on the walls of a container, of molecules or atoms moving at different velocities. Kinetic theory defines temperature in its own way, in contrast with the thermodynamic definition. All above clearly indicate that the “world” of kinetics has various sections. Therefore, the target of this Book is wide.

Graphene materials – Advanced applications
G.Z. Kyzas, A.C. Mitropoulos (Eds.)
pp. 1-238, Year: 2017
ISBN 978-953-51-3142-7, InTech - open science, Rijeka, Croatia
Graphene is a one-atom-thick layer of carbon atoms arranged in a hexagonal lattice. It is the building-block of Graphite (which is used, among others things, in pencil tips), but graphene is a remarkable substance on its own - with a multitude of astonishing properties which repeatedly earn it the title “wonder material”. Graphene is the thinnest material known to man at one atom thick, and also incredibly strong - about 200 times stronger than steel. On top of that, graphene is an excellent conductor of heat and electricity and has interesting light absorption abilities. It is truly a material that could change the world, with unlimited potential for integration in almost any industry. Graphene is an extremely diverse material, and can be combined with other elements (including gases and metals) to produce different materials with various superior properties. Researchers all over the world continue to constantly investigate and patent graphene to learn its various properties and possible applications, which include: touch-screens, transistors, computer chips, batteries, energy generation, supercapacitors.

Green adsorbents

pp. 1-122, Year: 2015
ISBN 978-1-68108-137-3, Bentham Science Publishers, UAE
One of the most recent trends in environmental technology is the research turn to green chemistry. It is general accepted that one of the most promising techniques for wastewaters treatment is adsorption. In this basis, numerous adsorbent materials have been synthesized up to now. However, there is a novel concept nowadays, which promotes the use of materials with the lowest possible cost. The economic crisis of the 2000s led researchers to turn their interest in adsorbent materials with lower cost. Attempts were already realized to use some low-cost adsorbent materials in order to firstly treat synthetic aqueous solutions and then real industrial samples. In this Book, the main scope is to describe these environmental-friendly materials namely “green adsorbents”, as I firstly introduce this term. it is meant the adsorption process using low-cost materials originated from: (i) agricultural sources and by-products (fruits, vegetables, foods); (ii) agricultural residues and wastes; (iii) low-cost sources from which most complex adsorbents will be produced (i.e., activated carbons after pyrolysis of agricultural sources).
