The voluntary and involuntary communication within the body occurs through the nervous system. The building blocks of the nervous system are electrically excitable neurons and neuroglia. They require large amount of ATP in a very short period of time to be able to reestablish resting membrane conditions after transmitting signals as electric current; entropy generation accompanies this process. Generally, a single neuron cannot provide the sufficient energy to achieve this and will need the support of neuroglia. This chapter includes theories of signal transmission along the neurons parallel with the basic thermodynamic knowledge to . . . describe energy supply and consumption. © 2018 Elsevier Inc.

Carbon capture and sequestration (CCS) emerges as a viable option for reducing atmospheric CO2 concentrations required for the mitigation of global warming and a sustainable energy future. The first step of CCS, which is the separation of CO2 from flue gas, is still very expensive limiting its use for industrial scale operations; so there is an extensive research going on, for the development of feasible capture materials. This chapter aims to provide a basic understanding about the current status and future directions of this search, providing an extensive literature review about the subject in addition to an illustrative example t . . .hat comparatively analyses materials for a better understanding of the factors affecting the adsorption capacity. © 2018 Elsevier Inc.

The major energy source in the world is solar energy. Only a small fraction of this energy is absorbed by plants to produce starch, for example, a glucose polymer, via photosynthesis. Glucose molecules are employed to produce adenosine triphosphate (ATP) in energy metabolism, which may be utilized to synthesize new plant cells. Herbivore animals survive on plants; carnivores prey on the herbivores. Both plant and animal cells store the chemical energy in their structures in the form of high-energy molecules. The raw material of fossil fuels is fossilized biological structures, for example, plant and animal cells. A similar conversio . . .n may be achieved by direct conversion, by skipping the fossil formation step, in biodiesel factories. The fossil fuel-rich areas of the world once housed rich ecosystems, before their inhabitants were fossilized. The age of the organisms and their resulting fossil fuels is typically millions of years. In biological structures, growth and reproduction and muscle work performance are achieved with ATP expenditure. In all of these processes substantial amounts of entropy are generated. Hormonal control of this energy uptake and utilization regulates functioning of anabolism and catabolism; the brain provides the balance between them. Imposing energy (calorie) restriction on the body may cause substantial changes in numerous body functions. © 2018 Elsevier Inc. All rights reserved
