Abstract: Ion irradiation is used to analyze and modify the structure of condensed matter. It can for instance be used to form and shape nanocrystals in solids as the understanding of the fundamental processes that take place in material under ion irradiation is important for all these applications of ion beams, and great interest from a basic science point of view. The mechanisms involved during ion irradiation-induced displacement of atoms in uniform bulk solids are fa...
This paper presents design analysis and implementation of a 0.5 KVA uninterruptible electronic power stabilizer (UPSz). Poor and instability of power supply delivery in Nigeria necessitated the need for a device that can stabilize voltage, protect equipment from damages and also provide power to the loads in the absences of electricity from the utility mains. This need motivated the d...
Various hand held devices have been invented and produced as far back as the 1st century B.C to smoothen fabrics. Over the years, irons have come in different shapes, sizes and principle of operation. Since the invention of electricity, electric irons have dominated the iron industry. In developing countries, Erratic and epileptic power supply owing to the inability of public power su...
The total energy of an element is the basic energy value from which other properties of the element can be calculated. Aluminum Arsenide (AlAs) and Indium Arsenide (InAs) are III – Arsenic binary semiconductors with indirect and direct energy band gap respectively. The total energy of each of them was calculated using the Projector Augmented Wave (PAW) method with the PBE-GGA for the exchange-correlation functional. The total energy were calculated and from the results gotten, the lattice c...
