Meet Rong Shang

Meet Rong Shang

  Dr. Rong Shang is a chemist. In her words, ‘We are always making new stuff.’ She and her colleagues build molecules combining organic atoms, like carbon and hydrogen, with metals, like gold and platinum. Originally from China, Dr. Shang studied and worked in three different countries before coming to Japan. Now she is Assistant Professor at Hiroshima University. She previously talked with us about her work in the lab. Here, she tells us about her path to becoming a scientist, how research is like a soccer game, and the importance of thinking beyond oneself.   What got you interested in science in the first place? Growing up in China,… Read more

A magnet that can be strong or weak

A magnet that can be strong or weak

Humidity and pressure control new magnetic crystals Researchers at Hiroshima University, CNRS, and Université de Strasbourg synthesized crystals with magnetic properties that can change continuously and reversibly, a world first. The study was highlighted as a cover article of the journal “Inorganic Chemistry,” a publication of the American Chemical Society in March 2016. Recently, the scientific community has had immense interest in new types of magnets with the potential to create the next generation of energy efficient devices through innovations using materials science techniques. Common magnets, like those holding reminders on home refrigerators or turning car motors, are made of metal and metal oxides.  Newer magnets can be made with… Read more

Lasers melt rocks to reveal development of super-Earths and how giant impacts make magma

Lasers melt rocks to reveal development of super-Earths and how giant impacts make magma

Advanced laser shock technique puts magmas under highest-ever pressures New experiments provide insight into how Earth-type planets form when giant asteroids or planetesimals collide and how the interiors of such planets develop. Researchers at Hiroshima University, Osaka University, Ehime University, University of Tokyo, and the Chiba Institute of Technology collaborated to publish their research in the August 3, 2016 issue of Science Advances. “Our results provide a better understanding how impact-generated magmas evolve and allow us to model Earth-type planets’ inner structures. Collisions at these extreme temperatures and pressures created our own Earth and may have also formed the mantles of other Super Earth planets, for example CoRoT-7b and Kepler-10b,”… Read more

Power up when the temperature is down

Power up when the temperature is down

Transporting power sources in the coldest places may be easier with a new re-chargeable, non-metallic battery from Japan. This “eco battery” could provide portable sources of power in environments like refrigerated factories or extreme winter environments. Chemists from Hiroshima University developed a new synthesis method for organic radical batteries that are re-chargeable and continue to function at below-freezing temperatures.  The specific model prototyped by the Hiroshima University team has greater voltage than previously reported styles from other research groups around the world.  The method used to create this battery is an improvement on a report from the same Hiroshima University laboratory earlier in 2016. Most electrical devices use a lithium-ion… Read more
