"As 3D printers gain increasing resolution, sodium ion batteries could eventually outperform lithium ion ones"
New, easily fabricated, high performance carbon microlattice electrodes could soon be used to make cheaper batteries powered by readily available sodium ions. The approach was published by Tohoku University researchers and colleagues in the journal Small. Lithium ion batteries are used in a wide ...
High-voltage environmentally friendly organic lithium-ion batteries
A joint research team from Tohoku University and the University of California, Los Angeles (UCLA) has made a significant advancement towards high-voltage metal-free lithium-ion batteries that use a small organic molecule, croconic acid. The breakthrough moves us closer to realizing metal-free, ...
Electron lens formed by light
Electron microscopy enables researchers to visualize tiny objects such as viruses, the fine structures of semiconductor devices, and even atoms arranged on a material surface. Focusing down the electron beam to the size of an atom is vital for achieving such high spatial resolution. However, when ...
“We could utilize two industrial waste products - ones that have historically been difficult to dispose of - and applied them to produce green hydrogen”
Sea pineapples, an edible ascidian, are a delicacy in Japan. The Tohoku region is famed for its sea pineapple production - known as hoya in Japanese. Now, a research group has established a new use for the scores of sea pineapple shells that get discarded every year. Led by professor Hiroshi ...
“Because water plays such an important role in chemistry and biology, and even in understanding our universe, we expect our findings to have a wide-ranging impact”
It plays a fundamental role in human existence and is a major component of our universe, yet there are still things we don’t understand about water. To address the knowledge gaps, a collaborative team of Institute of Industrial Science, The University of Tokyo, Kyoto University, and Tohoku ...
Novel monitoring and analysis method
Two-dimensional materials are incredibly thin. Typically only an atom thick, 2D materials exhibit highly desirable properties for advanced technologies, such as flexibility, superconductivity and more. Made from carefully transitioning individual components from gas or vapor to crystalline ...
Magnesium rechargeable batteries (MRBs), where high-capacity Mg metal is used as the anode material, are promising candidates for next-generation batteries due to their energy density, safety, and cost. However, the lack of high-performance cathode materials impedes their development. Like their ...
New method for creating metal-organic framework thin films
A research team has developed a new method for creating metal-organic framework (MOF) thin films that can be applied to sensors and electric devices. Like sponges, porous materials contain pores. The pore size affects the property of the material. For example, small pores create more absorbent ...
Toward the realization of next-generation flexible optoelectronic devices
In Japan Science and Technology Agency's Strategic Basic Research Programs, Associate Professor Toshiaki Kato and Professor Toshiro Kaneko of the Department of Electronic Engineering, Graduate School of Engineering, Tohoku University succeeded in clarifying a new synthesis mechanism regarding ...
A technique to generate large amounts of giant vesicle (liposome) dispersion has been developed. The technique involves adsorbing a lipid into a silicone porous material resembling a "marshmallow-like gel" and then squeezing it out like a sponge by impregnating a buffer solution. This work was ...
