Effect of Composition on the Optical and Electrical Properties of CuIn
Words • 2596
Pages • 10
Abstract Optical and electrical properties of chalcopyrite CuIn(SexS1-x)2 (0 ? x ? 1) amorphous thin films are investigated. The transmission has been measured as a function of the wavelength range from 200 to 2500 nm. The calculated optical energy band gap Eg and the Urbach tail (band tail width) Eu are found to decrease with increasing Se content. The refractive index, n, is calculated according to the Wemple- DiDomenico single oscillator model. The oscillator energy (E?), the dispersion energy (Ed),…...
Temmingh’s Compositional Process and Language
Words • 1058

Despite Temmingh's prolific output, the only comprehensive analysis that covers every aspect of his style is the chapter by Winfried Lindemann in the 1987 edited collection Composers in South Africa Today. Similarly, musicologist Veronica Franke provided a smaller-scale style analysis in her 2011 article. My discussion of Temmingh's compositional style and language builds on this existing literature but highlights his choral writing through musical examples. My discussion of Temmingh's style is organized into the following salient features: formal design, melody,…...

From the structural composition of purified nor-oleanane triterpenoids compounds, it is noticeably that inhibitory activities decline after the substitution of C-28 by sugar moieties. According to Liu et al, 2016, a free carboxylic group at C-28 is essential for XOD inhibition. The compounds brachyantheraoside B4 and L-rhamnopyranosyl-(1?2)- ? -L-arabinopyranosyl-30- norolean-12,20(29)-dien-28-oic acid) demonstrated the highest XOD inhibitory activities in comparison to (brachyantheraoside D1) since the hydroxyl group oxidation (brachyantheraoside B4), or exocyclic double bond (L-rhamnopyranosyl-(1?2)- ? -L-arabinopyranosyl-30- norolean-12,20(29)-dien-28-oic acid) at C-20…...

Finding thr Percentage Composition of Magnesium Oxide
Words • 1482
Pages • 6
Introduction According to Encyclopedia Britannica, the law of definite proportions is a “statement that every chemical compound contains fixed and constant proportions (by weight) of its constituent elements.” Using experimental data in this investigation, it will determine the percentage composition of magnesium oxide. Chemists believe that the energy released by the synthesis combustion reaction is sufficient to allow magnesium to also react with nitrogen in the air. This reaction produces magnesium nitride. What remains unclear is whether enough magnesium nitride…...

Planning Coursework Aim Our project is to find out what products are formed when copper carbonate decomposes. Copper has 2 oxides, Cu2O and CuO. We are told that one of the following two equations are correct: Equation 1 (Eqn1): 2 CuCO3 (s) --> Cu2O (s) + 2 CO2 (g) + 1/2 O2 (g) Equation 2 (Eqn2): CuCO3 (s) --> CuO (s) + CO2 (g) Calculations I have to find out which of the two are correct by experimentation. By looking…...

In this experiment, the rate of decomposition is calculated by measuring the volume of the product gas using water displacement. The reactant used is household bleach, which contains 5 to 6% of NaClO. The decomposition can be stated in this following equation: 2 ClO- (aq) --> 2 Cl- (aq) + O2 (g) To measure the rate of decomposition, a catalyst is needed to fasten the reaction. A suitable catalyst is Co2O3, which is produced from mixing Co(NO3)2 and bleach. The…...

Abstract: This lab was designed to observe the decomposition of hydrogen peroxide into it oxygen and water. The equation for this reaction is H202 H2O + +1/2O2 thus by measuring volume and pressure of O2 generated the amount of O2 generated can be calculated which in turn can be utilized to determine the concentration of water already in the H2O2 solution. The results determined that 3.02% of the solution is composed of H2O2. Introduction: This purpose of this experiment was…...

Abstract Our main purpose is to familiarise ourselves with a method to find the heat of decomposition of a compound (hydrogen peroxide). Firstly, we will be looking at information about calorimeter and what it meant by heat of decomposition. Also, we will try to understand why we have to subtract the heat absorbed by the calorimeter to find the heat of decomposition of hydrogen peroxide. Therefore, we found the heat capacity of calorimeter. After that, the enthalpy of decomposition of…...

Background DNA is an abbreviation for deoxyribonucleic acid, but it is usually known by its initials alone. DNA is found in practically all living organisms, and it is now known to carry genetic information from one cell to the next, and from one generation to the next. The units of inheritance, called genes, are actually sections of the DNA molecule. Nuclei of the cells of higher organisms contain thread-like bodies called chromosomes, which consist of DNA, wrapped around proteins. So…...

AIM: To carry out a lab experiment to decompose a carbonate using heat, also to carry out appropriate tests for the formation of products as a result of this decomposition. DISSCUSION: Carbonates are decomposed by heat into the corresponding oxides and carbon dioxide. The temperature of decomposition depends upon the activity of the metal; that is to say, the more active the metal, the more stable is the carbonate. Thus, the carbonates of sodium and potassium are stable at the…...
