  • Important Structures of AB2 Compounds
    Important Structures of AB2 compounds AB2 compounds have many different structures but many of them belong to one of the following 5 types. Fluorite (CaF2) The fluorite structure is very unique in so far as the close-packed ions are the cations and not the anions. In normal cases, the anion is the larger ion but in the case of CaF2, Ca is larger than F hence the structure is based on a cubic close-packing of the Ca2+ ions. There are 8 tetrahedral - holes in the unit cell of CaF2 and they are all occupied by F ions. One can notice that the only difference between fluorite and sphalerite (ZnS) is that in sphalerite only 4 of the tetrahedral holes are filled. Every fluorine anion is surrounded tetrahedrally by 4 calcium cations and every calcium cation is surrounded cubically by 8 flourine ions. In other words in the fluorite structure a (8,4)-coordination is observed. Antifluorite The antifluorite structure gets its name from the fluorite structure because it’s just the opposite i.e. the cations occupy the tetrahedral holes as compared to the anions in the fluorite structure. In this structure a cubic close-packing of the anions is observed. For example in K2O the cubic close-packing is made by oxide and the potassium occupy all 8 tetrahedral holes. The oxygen anions are surrounded by 8 potassium cations in a cubic way and the potassium cations are surrounded tetrahedrally by 4 oxygen ((4,8)-coordination). Cadmium Chloride (CdCl2) - In CdCl2 we have a cubic close-packed array of Cl ions.

  • Properties of Cds Chemically Deposited Thin Films on the Effect of Ammonia Concentration
    IOSR Journal of Applied Physics (IOSR-JAP) e-ISSN: 2278-4861. Volume 4, Issue 4 (Sep. - Oct. 2013), PP 01-07 www.iosrjournals.org Properties of CdS Chemically Deposited thin films on the Effect of Ammonia Concentration Munikrishna Reddy Y and Nagendra Vara Prasad M Department of Physics, S S B N Degree & PG College, Anantapuram – 515001, A.P Abstract : The effect of ammonia concentration on electrical properties, optical properties and structural properties of chemical bath deposited (CBD) Cadmium sulphide (CdS) thin films has been revealed. The films were prepared by using cadmium acetate as cadmium ion (Cd2+) source, thiourea as sulphur ion (S2-) source and ammonia as the complexing agent. Ammonia concentration was changed from 0.1 M – 3.0 M. Ammonia concentration at 2.0 M uniform, dense and continuously coated films were obtained. Not only typical cadmium- pure but also unusual sulphur deficiency phenomena were observed for CBD CdS thin films. In the present investigation, the carrier concentration varied form 1.831X106cm-3 to 1.026X106cm-3 when ammonia concentration is changed from 0.5M to 2.5 M. The direct band gap energy at 0.5M is 1.92eV while at 2.5M is 2.65eV. The surface morphology of as deposited thin films is almost smooth and no grains were observed clearly at low molar concentration and predominant grains at the concentration of ammonia is 2.0M. By estimated Cd:S ratio value is found to be 1.04 by using EDAX. The thin film deposited at 2.0M concentration shows the highest degree crystallinity.

  • Formation of Single Phased Mixed Crystals from Aqueous Solutions - an Overview
    An archive of organic and inorganic chemical sciences DOI: 10.32474/AOICS.2020.04.000187 ISSN: 2637-4609 Review Article Formation of Single Phased Mixed Crystals from Aqueous Solutions - an Overview CK Mahadevan* Department of Physics, Bharathidasan University, India *Corresponding author: CK Mahadevan, Department of Physics, Bharathidasan University, India, E-mail: Received: February 03, 2020 Published: February 13, 2020 Abstract Single phased mixed crystals are normally formed from two or more isomorphous end member crystals with some conditions. However, in some circumstances, it is possible that such mixed crystals can be formed/prepared/grown from aqueous solutions even when the end member crystals are not isomorphous with each other. An overview of various studies made in this direction is presented in this article focusing the results reported by the present author’s research group. Keywords: Aqueous solutions; Crystal growth from solution; Mixed crystals; Quasi mixed crystals; Solid solutions Introduction Single crystals are solids with regular (three dimensionally available where various crystals ranging in size from small to large periodic) arrangement of the constituent atoms, ions or molecules technology. Also, it is known that there are several factories crystals are grown. However, further research in the preparation and characterization of crystalline materials and growth of large preparation/growth of single crystals means careful arrangement into some fixed and rigid pattern known as a lattice. So, formation/ size crystals is very much necessary for our social requirements. of atoms, ions or molecules in a particular three-dimensional order. The most important question now is: How to tune or stimulate the There are four major categories of crystal growth methods, viz.

  • Attachment 3-1 Guidance for Developing Ecological Soil
    Attachment 3-1 Guidance for Developing Ecological Soil Screening Levels (Eco-SSLs) Eco-SSL Standard Operating Procedure (SOP # 1): Plant and Soil Invertebrate Literature Search and Acquisition OSWER Directive 92857-55 November 2003 This page intentionally left blank OVERVIEW Currently, there is a lack of clear guidance in setting terrestrial effect thresholds when conducting risk assessments. Without an EPA-approved, peer-reviewed, ecologically-based terrestrial effect database, the process to develop thresholds is problematic both to EPA, other federal agencies, states, and concerned private parties. Identification of published toxicity studies on invertebrates, microbial processes and plants is a key step in the derivation of benchmarks. The purpose of the Task Group 4, Standard Operating Procedure Number 1: Literature Search and Acquisition (referred to as TG4-SOP#1) is to document procedures used to identify and acquire potentially relevant toxicology literature for use in setting ecological soil screening levels. The literature search strategy is designed to locate worldwide terrestrial toxicity literature that includes the effects of chemicals of concern on terrestrial soil-dwelling invertebrates and plants. The literature acquisition process is designed to ensure timely acquisition of relevant publications. LITERATURE IDENTIFICATION Potentially relevant literature for developing ecological soil screening levels (Eco-SSLs) is identified by examining hard copies of relevant journals, bibliographies and guidance publications and through the use of a comprehensive computerized literature search strategy. These procedures are designed to locate worldwide terrestrial toxicology literature that includes the effects of specific toxic substances with an emphasis on exposure via soil. Paper-based Literature Identification The paper-based literature identification process includes the scanning of relevant review article bibliographies and key journals held in the U.S.

The nuclear hexadecapole interaction of iodine-127 in cadmium iodide measured using zero-field two dimensional nuclear magnetic resonance Ming-Yuan Liao and Gerard S. Harbison Department of Chemistry, University of Nebraska at Lincoln, Lincoln, Nebraska 68588-0304 (Received 25 June 1993; accepted.18October 1993) Two dimensional nuclear quadrupole correlation spectroscopy has been used to measure simultaneously the two nuclear spin transition frequenciesfor the iodine resonanceof cadmium iodide at zero magnetic field. Becauseof the layer structure and resultant polymorphism in this substance, conventional zero-field NMR spectra are inhomogeneously broadened by several hundred kHz. However, the 2D spectra obtained by our method are subject only to homogeneous linewidth, which for this compound is of the order of 5 kHz.
