SACI News October 2016

                                    

The student unrest on SA campuses is not over yet. This has had an impact on the SACI Office which is situated on the Wits campus. To ensure the smooth running of SACI during this time Laila Smith will work from home. She has a laptop, a copy of Pastel and a cell phone number 061 282 3477 for SACI business. This is already in place - so members might not even have realised that any change in communication had occurred. The decision to make the above changes was made after Laila’s car was damaged on campus a few weeks ago.

In other news – many of the SACI events scheduled for November will be rescheduled for December or early in 2017.

Noble Prize in Chemistry 2016

Nobel Prize in Chemistry awarded to creators of the World’s tiniest machines (WEDNESDAY OCTOBER 5 2016)

The winners of the 2016 Nobel Chemistry Prize are Jean-Pierre Sauvage, J. Fraser Stoddart and Bernard L. Feringa

“Both the Chemistry and Physics Nobel Prizes this year share the distinction of being material and molecular studies that have revealed much about the nature of matter but both also hint at new technology with a wide range of implications.

Tuesday, 4th October 2016, saw the announcement of the Physics prize, with half going to David J. Thouless of the University of Washington, Seattle, WA, and the other half to F. Duncan M. Haldane Princeton University, NJ and J. Michael Kosterlitz Brown University, Providence, Rhode Island, USA. The prize recognizes their theoretical discoveries of topological phase transitions and topological phases of matter. All three scientists are British born.

The scientists unlocked the secrets of exotics phases of matter using mathematics to help us understand the behavior and properties of superconductors, superfluids, and thin magnetic films. More specifically, they used topology, the branch of mathematics that describes continuous transitions from one shape or structure to another, that are preserved, deformations such as stretching and bending as opposed to tearing or gluing. The mathematics applies equally to abstract entities such as spacetime and black holes as well as everyday objects such as teacups and doughnuts as well as materials at the molecular and atomic levels.

In the early 1970s, Kosterlitz and Thouless overturned the theory that superconductivity or superfluidity could not exist in thin layers. They showed that superconductivity could occur at low temperatures and also explained the mechanism, a phase transition, that leads to the loss of superconductivity as the temperature rises above a critical point. In the 1980s, Thouless also explained earlier experiments with very thin electrically conducting layers and showed that topology could explain this too. Meanwhile, Haldane discovered how topology could explain the magnetic properties of certain materials.

A day later, the Chemistry prize was announced and will be shared by Jean-Pierre Sauvage of the University of Strasbourg, France, British-born Sir J. Fraser Stoddart, of Northwestern University, Evanston, Illinois, USA, and Bernard L. Feringa of the University of Groningen, the Netherlands. The prize this year is in recognition of the design and synthesis of molecular machines. Such a terse phrase belies the true enormity of their efforts of many years wherein they are laying the foundations for devices that work on a scale much smaller than any manufactured system and in some sense on a par with the machinery of living cells.
Sauvage took his first step towards a molecular machine in 1983 when he linked two ring-shaped molecules to form a catenane. Stoddart's work then extended this concept in 1991 to the so-called rotaxanes, a ring on a string, molecular system. And, in 1999 Feringa built a molecular motor. Together these three developments operating in parallel could one day allow technologists to build devices from the successors to these molecules”.

  • UNDERSTANDING XRF SPECTROMETRY 16 - 27 January, 2017 at UCT
    Introduction
    The Department of Geological Sciences will host a summer course for industry, research, and academia on the theory and practice of XRF Spectrometry from 16 to 27 January 2017. Initiated by Emeritus Prof James Willis, and now organized hosted by UCT in association with PANalytical B.V., this course presents the principles and practice of XRFS analysis. The emphasis will be on the application of the technique to geological materials, but applications in the cement, metals, and other industries and in environmental analysis will also be discussed.

    Lectures will be given mostly by Dr B.A.R. Vrebos on both wavelength and energy dispersive XRF spectrometry. There will be practical exercises that will include an introduction to modern wavelength and energy dispersive XRF spectrometers, and a practical introduction to the various procedures necessary for successful major and trace element calibrations and data reduction for both techniques. Participants will carry out tutorial calculations on test data sets to familiarize themselves with the procedures involved. They will receive a comprehensive set of course materials, including “Understanding XRF Spectrometry” (a two-volume book by James Willis and Andrew Duncan published in 2008 by PANalytical B.V.) together with lecture handouts, notes, and other useful documentation. As always, the contents of the course and its presentation will be vendor neutral. It is NOT a course on the instrumentation or software of any particular vendor.

    Participants completing the course should be in a strong position to successfully carry out XRF analysis on any vendor’s machine. A certificate of attendance will be issued.

    Course Structure
    The course is divided into two distinct parts:

    The first week comprises an introduction to the fundamentals of XRFS, qualitative analysis, selection and setting of instrumental parameters, matrix effects and how to deal with them, counting statistics, sampling procedures, sample preparation, and an introduction to quantitative XRFS analysis;

    The second week covers in detail quantitative analysis for both major and trace elements, background and spectral overlap corrections, standardisation, absorption and enhancement problems and corrections, influence (alpha) coefficient corrections, commercial and manufacturer’s software for correcting for inter-element matrix effects, special sample preparation techniques, analysis of small samples and solutions, and different applications of XRFS.

    Each week can be attended separately, BUT persons attending the second week on quantitative analysis MUST have attended previously the introductory first week, although not necessarily in the same year. This is a very full, very intensive course containing an enormous amount of detail and building very rapidly on itself. For participants with little theoretical or practical knowledge of XRFS, it is strongly recommended that only the introductory week be attended in the first year. After gaining a year's experience in the laboratory and building on the knowledge gained from the first week, such participants will be in a much stronger position to extract the maximum advantage from the second week of the course. It is strongly recommended that in their second year, such participants should attend the full two-week course in order to reinforce their basic knowledge and thus gain the greatest benefit from the full course. All previous participants who have adopted this approach have found it to be extremely valuable and beneficial.
