road constructions‚ IR thermography can be used to control the temperature of the single components. When flashes or a sine-modulated radiator heat an object‚ voids and debondings buried below the Phase display of a CFRP plate with defective bonding to concrete surface hinder the heat transfer. The resulting transient thermal contrast on the surface is made visible with pulse or lock-in thermography. Acoustic emission analysis Acoustic emission analysis uses sensors mounted on the

DEFINITIONS OF OXIDATION AND REDUCTION (REDOX) This page looks at the various definitions of oxidation and reduction (redox) in terms of the transfer of oxygen‚ hydrogen and electrons. It also explains the terms oxidising agent and reducing agent. Oxidation and reduction in terms of oxygen transfer Definitions • Oxidation is gain of oxygen. • Reduction is loss of oxygen. For example‚ in the extraction of iron from its ore: [pic] Because both reduction and oxidation are going on side-by-side

PUTTING IT TOGETHER: Classifying Chemical Reactions Purpose: To observe and differentiate between the four different types of chemical reactions. Variables: The independent variables are the sodium chloride‚ sodium carbonate‚ magnesium‚copper‚ copper (11) sulfate‚ silver nitrate‚ oxygen‚ lead(11) nitrate‚ sodium carbonate‚ copper (11) sulfate pentahydrate. The dependent variables are the chemical reactions that are being looked for. For example decomposition‚ synthesis‚ single displacement or double

Periodicity - repeating patterns within the periodic table & regular pattern in a property as you go from left to right across a period. Electrical conductivity - metallic elements good conductors Density - increases to a maximum in group 3‚ then falls. Ionisation enthalpy - Group 1-troughs - Group 0-peaks. Melting and boiling points - peaks group 4 - increases up to Group

Introduction Representing molecules as images allows us to impart a great deal of information concerning molecular structure. But these molecules can also be named‚ and there are occasions when this is more convenient than drawing a picture. In the early days of chemistry‚ the list of known compounds

universe. S1 contains atoms arranged in a regular array called a "lattice" (see Figure 1). Bonding electrons may be present. The nuclei of each atom act as weights and the bonding electrons as springs in an oscillator model. Non-bonding electrons may also be present‚ however in an ideal solid these electrons are not involved in carrying current. By extension‚ S1 contains no electronic conduction bands. The non-bonding electrons may be involved in Van der Waals (or contact) interactions between atoms. Given

Arene Molybdenum lab Introduction: Organometallic chemistry is the study of chemical compounds that contain carbon atoms bound to a metal atom. Organometallic compounds can contain main group elements‚ or more metallic elements such as zinc or carbon. These compounds tend to have carbon atoms bound to the metal center by σ-bonds. Alternatively‚ transition metals can be involved in the compound‚ which leads to a variety of interesting and diverse chemical characteristics. For example‚ a promising
