Tech & Science This year is the International Year of the Periodic Table of Chemical Elements—and today (March 6), the modern version celebrates its 150th birthday. To find out more about the table and how new elements are added to it, Newsweek spoke to Molly Strausbaugh, assistant director at the Chemical Abstracts Service—a division of the American Chemical Society. Below is a transcript of our conversation, which has been lightly edited for length and clarity. How was the periodic table developed? What’s the significance of March 6? The modern periodic table was developed by [Russian chemist] Dmitri Mendeleev and March 6 is significant because that was the day in 1869 that it was presented to the Russian Chemical Society and released publicly. In developing it, what Mendeleev did was start arranging elements in order of atomic weight and then grouping them. If you look at the construction of a periodic table, it goes down in rows and columns. I … [Read more...] about Periodic Table 150th Birthday: How Are New Elements Discovered?
A periodic table
The Periodic Table is a thing of beauty, but it can also feel pretty mysterious, especially if the last time you studied it was back in grade school. Now is a great time to get reacquainted. The International Year of the Periodic Table celebration marks 2019 as the 150th anniversary of Dmitri Mendeleev's discovery of the Periodic System, a way of organizing elements. The United Nations calls it "one of the most significant achievements in science, capturing the essence not only of chemistry, but also of physics and biology."A world of hydrogen, fermium and darmstadtium await you online with some interactive, colorful and even poetic versions of the Periodic Table of the Elements.Element Collection offers up one of the most visually interesting takes on the table with a version that pairs images to each element. You may see a nugget of gold, a puddle of mercury or an image of Albert Einstein to go along with Einsteinium. The photos are striking. A pictorial Periodic Table from … [Read more...] about The Periodic Table comes alive with haiku and pretty pictures
caption The Table of Disruptive Technologies. source Imperial College London Academics at Imperial Tech Foresight have created a periodic table of mind-blowing tech. The table is designed to be a visual conversation starter about where the world is going. It features 100 innovations, ranging from the benign and everyday, to the mind-blowing and potentially terrifying. Academics at Imperial Tech Foresight (ITF), an offshoot of Imperial College London, have been working to bring to life nebulous and intangible technological advances in a way you’ve never seen before. They have created a table of disruptive tech, taking inspiration from the periodic table of chemical elements. It contains 100 innovations, ranging from the benign and everyday, to the mind-blowing and potentially terrifying. To give you an example, cryptocurrencies (identified as Cr) are now part of our modern life, while battlefield robots (Br) sounds like something straight out of … [Read more...] about Academics created a periodic table of mind-blowing tech, and it’s a handy guide to how the world will change forever
The approach was developed by Daniel Packwood of Kyoto University's Institute for Integrated Cell-Material Sciences (iCeMS) and Taro Hitosugi of the Tokyo Institute of Technology. It involves connecting the chemical properties of molecules with the nanostructures that form as a result of their interaction. A machine learning technique generates data that is then used to develop a diagram that categorizes different molecules according to the nano-sized shapes they form. This approach could help materials scientists identify the appropriate molecules to use in order to synthesize target nanomaterials. Fabricating nanomaterials using a bottom-up approach requires finding 'precursor molecules' that interact and align correctly with each other as they self-assemble. But it's been a major challenge knowing how precursor molecules will interact and what shapes they will form. Bottom-up fabrication of graphene nanoribbons is receiving much attention due to their potential use in electronics, … [Read more...] about A New ‘Periodic Table’ for Nanomaterials
Scientists from Moscow Institute of Physics and Technology and Skoltech have demonstrated the high-temperature superconductivity of actinium hydrides and discovered a general principle for calculating the superconductivity of hydrides based on the periodic table alone. The results of their study were published in The Journal of Physical Chemistry Letters. High-temperature superconductivity is a phenomenon of zero electrical resistance in certain materials at temperatures above -196°C (the temperature of liquid nitrogen) that physicists, chemists and materials scientists worldwide have been intensely researching for decades, as room-temperature superconductors open up vast prospects for the power industry, transport, and other technology-driven sectors. Currently, the record holder in high-temperature superconductivity is hydrogen sulfide (H3S), which functions as a superconductor at 1.5 million atmospheres and temperatures of down to -70 oC. Such pressure levels can only be … [Read more...] about Scientists Discover a Link Between Superconductivity and the Periodic Table
