Physico-Chemical Behaviour of Beneficiated Indian Graphite
Graphite commonly called as plumbago is a soft, black crystalline form of naturally occurring carbon. Natural graphite is often found with carbonates and other carbon compounds and could be the result of their decomposition under conditions of high pressure and high temperature. Perfect crystals of graphite are very rare indeed and the imperfections and grain boundaries present in the materials are important in determining the properties of material. Impurities and absorbed gases also play an important role. Carbon materials are basically porous, having pores and cracks, sizes varying from angstrom units to several millimetre. The cracks often run along the lamellae of the carbon plane. India has a rich deposit of graphite. The total reserves of graphite in India is about 48 lakh tonnes. Properties of graphite varies from source to source depending on the mineral content, degree of graphitisation, crystal size, nature of crack and pores, specific surface areas, etc. Bulk of the graphite consumption is from the refractory Industry and major graphite suppliers in India are located in three states of India, i.e. Orissa, Jharkhand and Tamilnadu. Refractory industry uses graphite in purer form as higher ash percentage and lower degree of graphitisation deteriorates the refractory property. In presence of oxidising atmosphere, graphite oxidises very fast and deteriorates the brick property. Better the oxidation resistance of graphite better is the usefulness. The findings is expected to give an insight into the physico-chemical characteristics of Indian graphite which will ultimately lead to their best possible industrial and technological application.

Kinetics of Oxidation of Beneficiated Indian Graphite
Graphite is naturally found in association with various minerals and impurities, typically exhibiting a low percentage of fixed carbon. To enhance its purity, the material undergoes a sequence of crushing, grinding, and beneficiation processes. With repeated beneficiation, the fixed carbon content increases significantly, leading to the production of high-purity graphite. In India, the primary sources of graphite include Palamau in Jharkhand, Bolangir in Odisha, and Shivaganga in Tamil Nadu.Following physico-chemical evaluation of these graphite samples, their oxidation behavior was analyzed using Differential Thermal Analysis (DTA) and Thermogravimetric Analysis (TGA). The experiments were conducted under controlled atmospheres to investigate the reaction kinetics and determine the activation energy under specific conditions. Three oxidation temperatures were selected based on the oxidation peaks observed in the DTA/TGA curves.Kinetic modeling revealed that up to certain temperatures, the oxidation rate was primarily governed by the chemical reaction between carbon and oxidizing gas at the interface. At higher temperatures, a shift from chemical control to diffusion through a decarburized pore zone was observed. The oxidation process corresponded to models such as the phase boundary-controlled reaction, contracting disc, and two-dimensional diffusion.The formation of a decarburized zone alters the activation energy, reflecting a transition in mechanism. Additionally, particle size variations influence activation energy values, showing multiple slopes across temperature ranges.

Chemical Thermodynamics
Thermodynamics can never be made easy, but with the right approach and a consistent use of scientific terms it can be made less opaque, and it can give a person, who is prepared to try, an insight into how science explains why things happen the way they do. The approach adopted in this book will give readers a better understanding of how science works together with its limitations. Unfortunately, thermodynamics, or at least some parts of it, is a subject which (apart from quantum mechanics) probably causes most confusion and bewilderment amongst scientists. The majority of students do not understand or "get" thermodynamics, and it is considered a "hard" or difficult subject. There are multiple reasons for this. There is of course mathematics, and many thermodynamic texts appear to be lists upon lists of differential equations. Another reason is that thermodynamics is, as often as not, poorly taught by teachers/lecturers who themselves do not understand, or appreciate, or have any interest in the subject (often all three). This results not only in a lack of scientific rigorousness in the teaching of the subject with the resulting confusion, and sometimes teachers, lecturers and authors just get it plain wrong (this occurs surprisingly often). However, it need not be like this and although mathematics (including calculus) is required, it can be kept to a relatively elementary level in order to obtain an understanding of this most important of subjects. No one can pretend that the subject is easy, but it can be made more accessible by a rigorous definition of terms and concepts and ensuring that a consistency of use of these definitions is maintained.Highlighting the benefits of thermodynamics in practical science, the text gives an intuitive grasp of the major concepts of thermodynamics such as energy and entropy. Provides a new pedagogic approach to understanding and teaching chemical thermodynamics. Starting with a set of basic simple assumptions about what constitutes topics such as an ideal gas, theories are developed in a clear, concise and accessible manner that will either answer or at the very least give an insight into a surprising range of scientific phenomena including energy, heat, temperature, properties of gases, time and quantum theory. Assumes that the reader has essentially no knowledge of the subject. Mathematics (including calculus) is kept to a relatively elementary level in order to obtain an understanding of this most important of subjects. Provides the reader with a better understanding of how science works together with its limitations.

Thermochemical Conversion Processes for Solid Fuels and Renewable Energies
The increasing share of renewable energy sources is drawing attention to a critical challenge. The availability of wind turbines and photovoltaic solar cells is limited and difficult to predict. They usually provide a fluctuating feed-in to the grid, so energy reserves, e.g., conventional thermal power plants or energy storage systems, are necessary to establish a balance between electricity supply and demand. Various solutions can be adopted to maintain the security of supply and improve the flexibility of the future power system, such as improving the efficiency of technical processes in areas such as thermal power plants, cement and metallurgy industries, the use of advanced thermochemical conversion technologies such as gasification, the expansion of high-voltage transmission infrastructure, the promoting of renewable energy sources, the employment of large-scale energy storage systems, and the use of highly flexible power generation units with carbon capture and utilisation, such as combined-cycle power plants. Given this background, this Special Issue contains fundamental scientific studies on the latest research progress in the development and optimisation of gasification processes, renewable energy source "solar energy", synthesis of new hybrid nanocomposites and nanofluids, carbon capture, and energy storage systems.
