Hydrogen as a fuel can be used to tackle various energy challenges. It provides a number of ways to decarbonize various sectors like transport, chemical, steel industry, etc. This paper aims to assess the potential of hydrogen to serve as an economically viable fuel alternative to fossil fuels. Hydrogen’s physical properties play an important role to assess its potential and its advantages and disadvantages as fuel in hydrogen combustion and fuel cell propulsion systems. It has become global agenda to find a sustainable fuel as the greenhouse gas emission are increasing which in turn enhance environmental concern and the whole world is in search of environmentally friendly energy option. Hydrogen is similar to electricity which can be considered a versatile energy carrier that can be produced from various primary energy sources includin..... ReadMore -

Today, mainly oil, coal, and natural gas are used for energy in many countries. It is possible that these resources will be limited and will run out in the future. These resources, fossil fuels, are not renewable. Renewable energy is commonly described as energy sources that can be provided mostly above ground and continuously renewed without any production process. In recent years, the development and use of renewable energy sources have become essential. Choosing the materials used in this energy from nanomaterials would be beneficial. Therefore, in this study, nanomaterials with three different structures, such as body-centred cubic (bcc), face-centred cubic (fcc), and hexagonal closed-pack (hcp), were selected. Thermal conductivity and thermal expansion calculations have been made for these materials. Analyses..... ReadMore -

Nanotechnology is the projected ability to construct items at nanoscale from the bottom up, using techniques and tools being developed today to make complete, high-performance products. Nanotechnology for wireless communication will add on high quality, low cost, high sensitivity, reliability, robustness, high accuracy and computer function- ability. Though it has initial high research, development and manufacturing costs yet that can be compensated by low bulk manufacturing costs. Portable energy storage using super capacitor-battery hybrids based on new materials including carbon nano-horns and porous electrodes, fuel cell technologies, energy harvesting, and more efficient solar cells will help increase life of energy sources and transportability and reduce size and equipment weight Electronics and computing advances reach.....

The earth’s surface acts as a huge solar collector, absorbing radiation from the sun. In the UK, the ground maintains a constant temperature of 11-13o C several meters below the surface all the year around [1]. Among many other alternative energy resources and new potential technologies, the ground source heat pumps (GSHPs) are receiving increasing interest because of their potential to reduce primary energy consumption and thus reduce emissions of greenhouse gases [2]. Direct expansion GSHPs are well suited to space heating and cooling and can produce significant reduction in carbon emissions. In the vast majority of systems, space cooling has not been normally considered, and this leaves ground-source heat pumps with some economic constraints, as they are not fully utilized throughout the year. The tools that are currently available f..... ReadMore -

Water and water-related resources are in the first place among the natural resources of Georgia. The country is one of the first in the world in terms of hydropower potential (rivers, lakes, reservoirs, glaciers, groundwater, swamps). According to historical sources, the first supporter of the use of electric lights in Tbilisi was a wellknown public (Figure 1). Niko Nikoladze. Electricity generation in Georgia began in 1887, when thermal engines were installed in the city of Tbilisi to illuminate the Georgian Drama Theater. The works were carried out by the Swedish company “Blanche”. The initiator and inspirer of this work was the Georgian writer and public (Figure 2). Ilia Chavchavadze. The great shortage of electricity in Georgia, the growing demand for electricity allowed Georgian scientists and engineers, together with foreign spe..... ReadMore -

A novel reliable electrochemical sensing method was suggested for direct and sensitive determination of Nalbuphine (NB) analgesic drug. The effect of copper ions (Cu+2) as sensor towards NB determination was evaluated using cyclic voltammetry method and conductometry. They have been utilized to predict the possible electrochemical sensitivity and complexation reaction between Nalbuphine Hydrochloride (NB) and divalent copper (II) metal ions. Cyclic voltammetry study of CuSO4 .5H2 O in absence and presence of (NB) was performed using different concentration from Cus and NP·HCl at different scan rates. Redox mechanism of the system was determined from the resulted data. Moreover, thermodynamic parameters show valuable information about chelate metal ions. The resulted data obtained from cyclic voltammetry measurements was supported by cond..... ReadMore -

Faced with the growing energy shortages environmental pollution ecological deterioration; the development of clean and efficient new energy is the only way to solve the above problems. Hydrogen has become the most promising secondary energy of 21st century for its excellent advantages such as high combustion efficiency broad source no polluting product and reproducible ability. It has important strategic significance for solving the problems of environmental pollution and energy shortage puzzling all over the world. There is a certain degree of risk for compressed hydrogen storage in practical applications. Therefore, safe and reliable high-pressure storage of hydrogen is needed to be studied. In the currently developed hydrogen filling system, hydrogen is compressed through a compressor and stored in the tank as high pressure. In the fil..... ReadMore
