On the local front, I have been busy in Canterbury with events to encourage students to study chemistry and science. Last week saw more than 60 secondary school students invading the labs at CPIT to compete in our annual Year 12 chemistry competition. I get a great buzz out of watching the student teams work NZIC President together using wet chemistry to identify unknown organic compounds, as well as extracting key information from journal articles. And this weekend saw the Canterbury Career Expo where hundreds of local teenagers came to find out the various career and training options around New Zealand. I always look forward to talking to students who want to know what career options there are that can fulfil their interest in chemistry. I just hope I don’t bewil- der them too much once I have finished listing the many career and tertiary options available to them! I find it quite frustrating sometimes that many students only see chem- istry as a stepping stone to health sciences or engineering, I’d also like to thank Shimadzu for agreeing to sponsor and are not aware of the wider opportunities for study in- our Industrial and Applied Chemistry prize for the next volving chemistry.

Whether it is contributing to NZIC President challenges involving high value nutrition, aging well, pri- mary sector production, or our southern oceans, chemists will have roles to play in these areas. Furthermore, the addition of a 13th challenge focusing on science and soci- ety will focus on the promotion of science literacy within schools and across the wider community. The benefits of improving science literacy in New Zealand cannot be un- derestimated. This challenge will also provide opportuni- ties in the area of educational research, something I know will interest our members who are already active in this area. 62 Chemistry in New Zealand July 2013 New Zealand Institute of Chemistry NZIC News supporting chemical sciences July News AUCKLAND Congratulations to Dr Cosmin Laslau Part A 2013; 83(2), 227-34). who was one of the five PhD students The first Chemistry Pub Quiz of the from The University of Auckland Many visitors gave excellent talks NZIC Auckland Branch was held at awarded the prestigious Vice-Chan- over the past few months.

  • Glossary Glossary
    Glossary Glossary Albedo A measure of an object’s reflectivity. A pure white reflecting surface has an albedo of 1.0 (100%). A pitch-black, nonreflecting surface has an albedo of 0.0. The Moon is a fairly dark object with a combined albedo of 0.07 (reflecting 7% of the sunlight that falls upon it). The albedo range of the lunar maria is between 0.05 and 0.08. The brighter highlands have an albedo range from 0.09 to 0.15. Anorthosite Rocks rich in the mineral feldspar, making up much of the Moon’s bright highland regions. Aperture The diameter of a telescope’s objective lens or primary mirror. Apogee The point in the Moon’s orbit where it is furthest from the Earth. At apogee, the Moon can reach a maximum distance of 406,700 km from the Earth. Apollo The manned lunar program of the United States. Between July 1969 and December 1972, six Apollo missions landed on the Moon, allowing a total of 12 astronauts to explore its surface. Asteroid A minor planet. A large solid body of rock in orbit around the Sun. Banded crater A crater that displays dusky linear tracts on its inner walls and/or floor. 250 Basalt A dark, fine-grained volcanic rock, low in silicon, with a low viscosity. Basaltic material fills many of the Moon’s major basins, especially on the near side. Glossary Basin A very large circular impact structure (usually comprising multiple concentric rings) that usually displays some degree of flooding with lava. The largest and most conspicuous lava- flooded basins on the Moon are found on the near side, and most are filled to their outer edges with mare basalts.

The drivers for central government are very different to those for local government. These institutions will come under increasing strain from the pace of change, our limited financial and natural resources, and increasing global unrest and nationalism. We believe that the next few years should be about creating and supporting trust between individuals, communities, and organisations.

James Boerio i ABSTRACT Plasma processes, including plasma etching and plasma polymerization, were investigated for the pretreatment of aluminum prior to structural adhesive bonding. Since native oxides of aluminum are unstable in the presence of moisture at elevated temperature, surface engineering processes must usually be applied to aluminum prior to adhesive bonding to produce oxides that are stable. Plasma processes are attractive for surface engineering since they take place in the gas phase and do not produce effluents that are difficult to dispose off. Reactive species that are generated in plasmas have relatively short lifetimes and form inert products.

  • 2010 Academy Annual Report
    This document has been created from historical website content. 2010 Academy Annual Report The 2010 Academy Annual Report details the accomplishments of the Academy of the Royal Society of New Zealand throughout the year. Chair’s foreword In January 2010 the final act of “embracing the Humanities” within the Royal Society took place with the signing of an MOU between Te Whainga Aronui The Council for the Humanities and Te Apārangi the Royal Society of New Zealand. President Dr Garth Carnaby described this as landmark decision for both organisations. “For the first time there will be an organisation in New Zealand that promotes excellence in research and scholarship across all the disciplines and areas of knowledge.” The CV’s of the existing fellows of the Council for the Humanities were reviewed by the Academy Executive and these people were admitted to the Fellowship by a special resolution at the Fellow’s AGM. The Academy has continued to provide “information pieces” and forward- looking contributions on present and emerging debates that were introduced in 2009. In 2010, 2 information statements were prepared. Sea Level Rise: Emerging Issues recounted the significant changes in the scientific understanding of this issue since the 2007 Assessment Report by the IPCC. The Darfield Earthquake: The Value of Long-term Research was produced to document the research conducted in New Zealand over many years on how to construct and strengthen buildings to improve performance during large earthquakes. The application of this science and engineering undoubtedly played a big role in limiting the damage and injury caused by the 2010 Christchurch earthquake.

  • Item Specifications High School Osas Science Test
    ITEM SPECIFICATIONS HIGH SCHOOL OSAS SCIENCE TEST 2014 Oregon Science Standards (NGSS) Introduction This document presents item specifications for use with the Next Generation Science Standards (NGSS). These standards are based on the Framework for K-12 Science Education. The present document is not intended to replace the standards, but rather to present guidelines for the development of items and item clusters used to measure those standards. The remainder of this section provides a very brief introduction to the standards and the framework, an overview of the design and intent of the item clusters, and a description of specifications that follow. The bulk of the document is composed of specifications, organized by grade and standard. Background on the framework and standards The Framework for K-12 Science Education is organized around three core dimensions of scientific understanding. The standards are derived from these same dimensions: Disciplinary Core Ideas The fundamental ideas that are necessary for understanding a given science discipline. The core ideas all have broad importance within or across science or engineering disciplines, provide a key tool for understanding or investigating complex ideas and solving problems, relate to societal or personal concerns, and can be taught over multiple grade levels at progressive levels of depth and complexity. Science and Engineering Practices The practices are what students do to make sense of phenomena. They are both a set of skills and a set of knowledge to be internalized. The SEPs (Science and Engineering Practices) reflect the major practices that scientists and engineers use to investigate the world and design and build systems.

  • News Release
    NEWS RELEASE Date: August 15, 2016 From: The Kosciuszko Foundation, Pittsburgh Chapter Contact: Mary Lou Ellena [email protected] 412.855.8330 -- FOR IMMEDIATE RELEASE -- CMU Professor Selected to Receive “Outstanding Polonian” Award Pittsburgh, PA -- The Pittsburgh Chapter of the Kosciuszko Foundation will present its annual Outstanding Polonian Award to Carnegie-Mellon Professor Krzysztof Matyjaszewski, PhD at a luncheon to be held Saturday, September 17, 2016. As a Distinguished Professor in the Department of Chemistry within CMU’s Mellon College of Science, Dr. Matyjaszewski is an internationally recognized polymer chemist who is renowned for his vision, educational leadership and research innovation. His discovery of Atom Radical Transfer Polymerization (ATRP) led to significant innovations in the field of polymer chemistry and revolutionized how macromolecules are made. Macromolecules are necessary for life and include carbohydrates, lipids, nucleic acids, and proteins. Dr. Matyjaszewski has received considerable international recognition for his contributions to science. In 2004 he received the annual prize of the Foundation of Polish Science, often referred to as the "Polish Nobel Prize.” In 2005 he became a foreign member of the Polish Academy of Science and in 2007 received an honorary degree from Lodz Polytechnic (Poland). IN recognition of his accomplishments the Polish Chemical Society awarded him the Marie Sklodowska-Curie Medal in 2012. He has received honorary degrees from the University of Ghent (Belgium), the Russian Academy of Sciences, the University of Athens (Greece), the Polytechnic Institute of Toulouse (France), the Pusan National University (South Korea) and the Université Pierre et Marie Curie, Sorbonne (France). Most recently Professor Matyjaszewski joined a research team at CMU under a $3 million grant to provide the US Military with drones, gliders and other delivery vehicles that can “vanish” once they safely deliver supplies or intelligence to troops.
