In this way, a 19 hazardous waste from the tertiary aluminium industry was studied for its use as a raw 20 material in the synthesis of an added value product, boehmite. This waste is classified as 21 a hazardous residue, principally because in the presence of water or humidity, it releases 22 toxic gases such as hydrogen, ammonia, methane and hydrogen sulphide. The low 23 temperature hydrothermal method developed permits the recovery of 90% of the 24 aluminium content in the residue in the form of a high purity (96%) AlOOH (boehmite). 25 The method of synthesis consists of an initial HCl digestion followed by a gel 26 precipitation. In the first stage a 10% HCl solution is used to yield a 12.63 g.l-1 Al3+ 27 solution.

  • Thermal Transport in Thorium Dioxide Nuclear Engineering and Technology
    Nuclear Engineering and Technology 50 (2018) 731e737 Contents lists available at ScienceDirect Nuclear Engineering and Technology journal homepage: www.elsevier.com/locate/net Original Article Thermal transport in thorium dioxide Jungkyu Park*, Eduardo B. Farfan, Christian Enriquez Kennesaw State University, Department of Mechanical Engineering, Kennesaw, GA 30144, USA article info abstract Article history: In this research paper, the thermal transport in thorium dioxide is investigated by using nonequilibrium Received 28 September 2017 molecular dynamics. The thermal conductivity of bulk thorium dioxide was measured to be 20.8 W/m-K, Received in revised form confirming reported values, and the phonon mean free path was estimated to be between 7 and 8.5 nm 20 December 2017 at 300 K. It was observed that the thermal conductivity of thorium dioxide shows a strong dependency Accepted 12 February 2018 on temperature; the highest thermal conductivity was estimated to be 77.3 W/m-K at 100 K, and the Available online 1 March 2018 lowest thermal conductivity was estimated to be 4.3 W/m-K at 1200 K. In addition, by simulating thorium dioxide structures with different lengths at different temperatures, it was identified that short Keywords: Molecular Dynamics Simulation wavelength phonons dominate thermal transport in thorium dioxide at high temperatures, resulting in Nuclear Fuel decreased intrinsic phonon mean free paths and minimal effect of boundary scattering while long Thermal Transport wavelength phonons dominate the thermal transport in thorium dioxide at low temperatures.

  • Chemistry Workbook
    Bridging the gap 2020 Ripon Grammar School 1 2 Introduction Advanced level Chemistry is a demanding and exciting course. In order to be prepared for your start in September a number of areas from GCSE chemistry are needed to be ‘known’ thoroughly. To help you make the transition as smoothly as possible we have put together this series of exercises. When you start in September you will be expected to have completed the exercises within this booklet and know the material within. It is by no means ALL you need to know but the very foundations of the exciting journey you are about to start. If you have difficulties or confusions there are a number of suggested online resources you could try. There will be opportunities to discuss concerns with staff at the beginning of the year but you should have made significant headway independently. This booklet contains some notes to act as a reminder. If you struggle with a particular area you should investigate the suggested support resources including your GCSE notes. There are exercises for you to complete, the answers are at the end. Contents Periodic Table 2 Topics Writing formulae 4 Equations 7 Moles 10 Atomic Structure 15 Identifying Bonding and Structure types 19 Answers to exercises 20 3 Writing formulae Objectives: • Know the common ions • Be able to construct formulae for common ionic substances • Know the formulae of some common covalent substances Common Ions (you need to know these): Putting together an ionic formula: The charges must balance.

Three different approaches have been used; Telefax: i. deposition of antimony selenide, Sb2Se3, on pre-sputtered copper films, 018 – 471 30 00 ii. deposition of antimony and selenium in two steps on pre-sputtered copper films and Hemsida: iii. deposition of selenium on pre-sputtered stacked films of copper and antimony. The http://www.teknat.uu.se/student films were analyzed using optical imaging, SEM, EDS, XRD, and UV-Vis spectroscopy. It was found that the Cu-Sb-Se system is complicated, containing numerous phases with low crystallographic symmetry compared with chalcopyrite materials.
