In physics and chemistry, plasma is a state of matter similar to gas in which a certain portion of the particles are ionized. After sufficient heating a gas dissociates its molecular bonds, rendering it into constituent atoms. However, further heating may also lead to ionization (a loss or gain of electrons) of the molecules or atoms of the gas, thus turning it into a plasma, containing charged particles: positive ions and negative electrons.[1] The presence of a non-negligible number of charge

Senior seminar November 19, 2009 Dynamics of glass forming liquids and polymer under hydrostatic pressure By: Riccardo Casalini Last seminar Dr Riccardo Casalini talked about glass formation under pressure. His research is focused on the concept of dielectric spectroscopy. Dielectric Spectroscopy, the measurement separates molecular process on the basis of response time, providing a unique relaxation frequency along with a signature variation with frequency. If an electric field is applied

ABSTARCT Determination of boiling point and melting point of the organic liquids, in practice determining the boiling point of ethyl and Isopropyl Alcohol and the melting point of benzoic acid and Urea. However, the boiling point of a liquid is the temperature at which the pressure of the vapor above a liquid equals the existing pressure. As we heat a liquid, the pressure of the vapor above the liquid slowly increases. When this pressure equals the pressure presented in the container, the

Energy can be converted from one form into another in three basic ways know as the action of force. The first one is gravitational forces which is when gravity accelerates a falling object, its converts its potential energy to kinetic energy. Likewise, when an object is lifted the gravitational field stores the energy exerted by the lifter as potential energy in the earth-object system. The second one is electric and magnetic force fields which is charged particles, upon which electrical fields exert

CHAPTER 3 Elements of solid state physics • Semiconductors, insulators and metals • Semiconductors • Insulators • Metals Prof. Dr. Beşire GÖNÜL Semiconductors, Insulators and Metals The electrical properties of metals and insulators are well known to all of us. Everyday experience has already taught us a lot about the electrical properties of metals and insulators. But the same cannot be said about “semiconductors”. What happens when we connect a battery to a piece of a silicon;

Aperture Theory And The Equivalence Theorem Adriaan J. Booysen, Member, IEEE Grintek Avitronics, P 0 Box 8492, Centurion, 0046 I. INTRODUCTION The equivalence theorem [I] provides an elegant method for analysing electromagnetic radiation and scattering from structnres. A specific class of problems is where a source is enclosed within a structure which forms a cavity with an aperture, as depicted in Figure 1. From a radiation point of view, the fields wilhi the cavity are not of any rcal interest

Solvation Models There are some methods which are established in order to observe the effect of solvation in a system. These models are distinguised as Polarizable Continuum Model or Implicit model, Explicit model and Hybrid Explicit Model. These three models subdivide and they will be discussed further. While using these models, the one which fits to the system should be chosen carefully since reducing the cost and time is very significant. When the time gets longer, more payment is done and also

Figure 1 shows level of specific gravity for compound A in individuals who were tested by the Environmental Protection Agency. Standard deviation of compound’s values were used to create error bars. Figure 2 shows the value of specific gravity of compound B for the individuals who were tested by the Environmental Protection Agency after reports came that people got sick due to compounds in new cleaning agent entered nearby water supply. Standard deviation of compound’s values were used to

PepsiCo’s Five Forces Analysis PepsiCo’s world-wide success is related to its business capabilities, especially in overcoming the challenges and problem shown in this Porter Five Forces analysis. Michael Porter developed the Five Forces analysis model to determine the most significant external factors that influence Company. For PepsiCo to maintain its market rank as the second largest food-and-beverage company in the world, it must show the potential problems identified in this model. PepsiCo
