Chemical material. Silicon

In my research paper, I want to talk about such an important element as silicon. I'm not going to focus on its biological importance for living organisms. More attention is allocated for its use in tech world, because it this element was a member of the technological revolution and made the world as we see it now.
SILICON is a chemical element of the subgroup (C, Si, Ge, Sn and Pb) of the periodic system of elements, nonmetal. The crystal structure of silicon is shown in Figure 1. Silicon was isolated in 1811 by Znan Gey-Lussac and L.Tenarom by Continue reading...

Abstract
The paper introduces a brief review on solar cells and different techniques that have been used to increase the efficiency. The discussion is then directed towards the current and cutting edge challenges on the issues related to fabrication and the increase in the solar cell efficiency. Primary focus is on the use of nanostructures in the context of solar cell fabrication and performance. The paper specifically informs on the use of techniques which focus on light absorption and trapping . One such technique which is reported in the paper is the fabrication of transparent Continue reading...

Abstract

The aim of this paper is to investigate an effect of aging time on mechanical properties and wear characteristics of Al12Si3Cu1Mg1.78Ni alloy. This alloy is used for aluminium piston parts. The solution treatment was carried out at 500oC for 5 hours followed by water quenching. Subsequent aging was carried out at 1800C with various solution treatments times for 1, 2, 4, 6, 8, 9, 10, 12, 16, 20 and 24 hours. As-cast microstructure of this alloy contains eutectic Si, Mg2Si, Al2Cu, Al3Ni and various other intermetallic phases. After solution treatment, the flake like and acicular eutectic silicon appears to Continue reading...

A Study on the effects of Squeeze Pressure on Microstructure, Mechanical Properties, and Wear Characteristics of Near-Eutectic Al-Si Piston Alloys with variable Cu contents.

Abstract:

This paper discusses the effects of squeeze pressure on the microstructure, wear characteristics and the mechanical properties of near eutectic Al-Si piston alloys with variable Copper (Cu) content. The paper starts with a description of Al-Si alloys and the features that make them desirable for use as piston alloys. The impact of alloying elements on the mechanical properties, microstructure and wear characteristics are also discussed where it is determined that adding alloying elements such as Continue reading...

Abstract

This report discusses and analyzes solar panels used to power outdoor lighting and makes a recommendation of the best type based on cost and efficiency. Research identified three different types of solar panels: monocrystalline silicon, polycrystalline silicon, and building integrated photovoltaics. The report presents factors that can affect the performance of solar panels such as solar altitude, solar radiation (irradiance), azimuth, and the condition of the solar panels. Based on research, Katsuno and Lotfithe elaborates on how to make a complete solar system and lists five parts that must be installed: solar panel, battery, charger controller, battery, convertor and Continue reading...

Seleris is undertaking a complex project termed as Silicon 6. Martha McCaskey is the project leader. She was promised that upon the completion of the project she would be promoted to group Manager. However, like any other project Silicon 6 has experienced some difficulties and challenges in the production of a new range of chips. After being advised that the organization needed to develop a new chip, McCaskey was entrusted with the role of obtaining the cost structure and completing the project in a timely manner. However, the chip to be used by the organization is relatively expensive, and Continue reading...

Energy is the basic need in the present times. Without energy, the sign of life would not be possible. Wheel of life cycle would be stopped if there is no energy. In modern times, life is being progressed day by day because of the resources and energy is one of them. Hence with the advancement in time, energy and its needs are also being increased.

Further in this paper, we will discuss about different solar cells and their working capability with efficiency.

Although there are different types of solar cells but here in our research paper we will discuss about two different cells and their comparison. One is the multicrystalline silicon solar cells (Basu et.al 2571) Continue reading...

Abstract:

In this research, the effects of pressure on the wear resistance characteristics, mechanical properties and the microstructures of Al-Si piston alloys that have variable Magnesium (Mg) content is studied. The paper begins with an explanation of the desirable properties of eutectic Al-Si alloys and why their chemical and mechanical properties are desirable in the fabrication of light weight machine components. The methods of strengthening the alloys further using alloying elements such as Ni, Cu and Mg, and applying heat treatment are also discussed. The paper also places major emphasis on the addition of Magnesium, and compares the traditional gravity Continue reading...

Communication: Past and Present

Communication: Past and Present
No matter the time, it appears that communication in all its forms is important to companies looking to hire new employees. Whether communicating verbally or through script, employers expect new hires to be able to communicate intelligently, professionally, and without the use of slang. Nonverbal forms of communication, such as eye contact and listening skills have also seemingly always been important to employers. The relevancy of these articles stands true through time because few things have changed; those attempting to get hired should take heed to what employers are looking for in terms of communication Continue reading...

Introduction

The medical field is characterized by various equipment and materials that are used to enhance the provision of medical services. Each of these materials is designed in a manner that meets a specific need or medical purpose. In restorative dentistry, dental impression materials have been used to fulfill various needs among patients (Anusavice & Phillips, 2012). Some scholars have argued that the use of such materials is a means to an end in that, they enhance the services provided to patients, hence facilitating recovery. Dental impression materials are basically used to perform activities that entail recording the shape of a Continue reading...
