Osaka Metropolitan University scientists developed a simple, rapid method for identifying food poisoning-inducing bacteria based on color differences in the scattered light of composite structures consisting of gold, silver, and copper nanoparticles and polymer particles.

This new research has clarified the computational conditions needed to use ASP, a major development for making quantum chemical calculations on a quantum computer practical for chemical or materials research.

A research group of Professor Makoto Tsubota and Specially Appointed Assistant Professor Satoshi Yui, both from the Graduate School of Science and the Nambu Yoichiro Institute of Theoretical and Experimental Physics, Osaka Metropolitan University, in cooperation with their colleagues from Florida State University and Keio University, revealed that there are laws of vortex diffusion in superfluid helium-4 (He II) at extremely low temperatures, near absolute zero (−273°C). In this study, by conducting a systematic numerical study and comparing the results with experimental observations, the research group found that quantum vortices cause "superdiffusion" over short periods of time and "normal diffusion" over longer periods of time, similar to the movement of pollen in still water.

Structural features of SiO2 glass under pressure.
27 Jun 2022
Understanding the structural origin of the anomalous properties of SiO2 liquid and glass is of great interest in a wide range of scientific fields. The fraction of the S state with tetrahedral symmetry structure is considered to be the controlling parameter of the anomalous properties of SiO2 liquid in theoretical studies. However, it has not been well identified in experiments. In this work, we find experimental evidence of tetrahedral symmetry breaking in SiO2 glass under pressure.

Osaka Metropolitan University scientists detected, for the first time, collective resonance at remarkably high and broad frequency bands. In a magnetic superstructure called a chiral spin soliton lattice (CSL), they found that resonance could occur at such frequencies with small changes in magnetic field strength.

Balances depict pentacene’s photostability
17 Jun 2022
A research group led by Professor Yoshio Teki of the Osaka Metropolitan University Graduate School of Engineering has succeeded in developing a new pentacene derivative that is more than 100 times more photostable than TIPS-pentacene, a photostable pentacene derivative. Additionally, the team has further clarified the ultrafast excited state dynamics in this system. In the pentacene moiety of this system, we were able to demonstrate that the transition from the excited singlet state to the excited triplet state occurs ultrafast in the time region of a 10-13 seconds. In purely organic materials without heavy atoms such as rare metals, such intersystem crossing usually occurs on time scales longer than 10-9 seconds. The empirical results of this study are expected to be applied as a method for stabilizing and developing light-unstable materials in the future.

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.

Researchers from the Osaka Metropolitan University Graduate School of Engineering have successfully developed a new technique allowing them to observe gas molecules packing into metal-organic frameworks (MOF) using infrared spectroscopy. Their innovation was to measure polarized light absorption of guest molecules in a MOF film to deduce molecule alignment using this common piece of lab equipment. This method is the first to show guest alignment and does so in real-time, while using an accessible and easily adoptable experimental setup. A short video (4 min) recreating their spectrometer modifications can be found in the Reference section.

Tile patterns in which the same shape is laid out without gaps are found in the compound eyes of insects. Hexagonal tile patterns are common while shrimp eyes have a square pattern. We investigated tile pattern formation using Drosophila and revealed that the compound eye tile pattern is controlled by a geometrical division mechanism, Voronoi tessellation, in addition to physical constraints determined by the combination of the regular distribution and growth of the individual eyes.
