Researchers at Kanazawa University report in JACS Au how they have developed operando scanning ion conductance microscopy to allow simultaneous measurements of changes in the anode surface topography of a lithium ion battery during use, as well as the varying ion concentration with depth. Combining both types of information should help researchers evaluate the correlation between the two to design better batteries.

A research group from the Graduate School of Engineering at Osaka Metropolitan University has shown that 3C-SiC exhibits high thermal conductivity equivalent to the theoretical value, based on thermal conductivity evaluation and atomic-level analysis, for the first time. They demonstrated that a 3C-SiC film on silicon substrate had a high thermal conductivity and expect that fabricating large-diameter wafers can be achieved at a low cost. The discovery should lead to improved heat dissipation in everyday electronic devices.

A research team led by an associate professor at Tohoku University has developed a microscopic fiber equipped with actuators and biochemical sensors. The breakthrough could be used to develop smart catheters and lead to further advancement in robotics.

A research group, at the Osaka Metropolitan University Graduate School of Engineering, has succeeded in measuring spin transport in a thin film of αNPD molecules—a material well-known in organic light emitting diodes—at room temperature. They found that this thin molecular film has a spin diffusion length of approximately 62 nm, a length that could have practical applications in developing spintronics technology. In addition, while electricity has been used to control spin transport in the past, the thin molecular film used in this study is photoconductive, allowing spin transport control using visible light.

6th NanoLSI Symposium: International symposium on Nanoprobe Technology for Understanding Molecular Systems in Kanazawa, Japan

A research group at Osaka Metropolitan University has developed a drug delivery system that activates a strong cellular immune response to attack cancer cells, using one-tenth of the amount of antigen needed in the group’s previous work. By incorporating positively charged cationic lipids into liposomes and adding negatively charged pH-responsive polysaccharides to the surface, the research group increased the uptake efficiency of liposomes encapsulating cancer antigens by dendritic cells by approximately five times, which increased cytokine production by about 100 times. This increased M1-type macrophages, which activate cancer immunity, and decreased M2-type macrophages, which promote cancer growth.

Two new approaches could help scientists use existing sequencing technology to better-distinguish RNA changes that affect how their genetic code is read.

Rie Makiura, Associate Professor at the Graduate School of Engineering, Osaka Metropolitan University has published a review article on the facile synthesis of nanosheet materials with precise regular nanoscale pores. In 2010, Professor Makiura’s research group succeeded in fabricating the world's first MOF (metal-organic framework) nanosheets on the surface of water using a simple low-energy process. The procedure, which involved adding drops of suitably chosen molecular components to the water surface took advantage of the same phenomenon that causes the formation of oil films and led to the creation of nanosheets of exceptional integrity and stability. In the present review article, Professor Makiura describes the MOF nanosheets developed by her group so far and provides a detailed description of their characteristics and comparison with other MOF nanosheets reported around the world. In addition, she describes the formation mechanism of the MOF nanosheets on the water surface.

Dr. Nishikawa at Osaka Metropolitan University focused on the Kondo effect on minimal ferrimagnetism and attempted to elucidate it theoretically. As a result, they found that the Kondo effect occurred via multiple "quantum entangled states" depending on temperature and other factors. They also found that the Kondo effect suppressed electrical conductivity through minimal ferrimagnetism, when usually it is amplified in many other cases.
