Design Lab for our Future Co–existence

TFC×TEL Collaboration Program: Designing a Digital and Sustainable Society

Information

Elements in the universe are still a mystery, such as where and how various elements have been created in the 13.8 billion years since the Big Bang, and how we use these elements to sustain life activities. The mysterious of synthesis might be interested. These lectures will be focused on the discovery of nihonium, the first Japanese element to be added to the periodic table of elements and the current research on the discovery of the new elements.

Abstract

Lecture 1:
We are made of stardust

Toshimi Suda
(Tohoku University)

Right after the Big Bang 13.8 billion years ago, there were no chemical elements in the Universe. But now, you can find a wide range of elements on Earth, and some of them (12 essential elements and 15 essential trace elements) are very important to sustain our life. In this lecture, we will discuss how these elements came to be in our universe – when, where, and how these elements, which are closely related to us, were synthesized.

Lecture 2:
The evolving periodic table of the elements

Hiromitsu Haba
(RIKEN Nishina Center for Accelerator–Based Science)

Since ancient times, humans have been searching for new elements, revealing their unknown properties, and enriching people's lives. In this lecture, the evolving periodic table and nuclear chart, as well as the creation of artificial elements will be explained, while unraveling the history of element discoveries. Nihonium was not the first attempt to search for new elements in our country. Nipponium discovered by Masataka Ogawa and element 93, which was missed by Yoshio Nishina and others, will also be explained.

Lecture 3:
Discovery of nihonium and toward the discovery of further new elements

Kouji Morimoto
(RIKEN Nishina Center for Accelerator–Based Science)

Currently, there are 118 elements discovered and recognized. Among these, elements from hydrogen (element 1) to uranium (element 92) exist in nature, while elements 93 and above have been discovered through artificial synthesis. In this lecture, I will discuss the synthesis and confirmation of nihonium (element 113), discovered in Japan, and explain ongoing research efforts aimed at discovering more new elements.
