An international team led by Osaka University used experimental measurements and theoretical modeling to better understand the shape formed by the protons and neutrons in the atomic nucleus of calcium-40. They found that destructive interference affects the mixture of elongated and spherical states. This research may help shed light on the reasons for the relative stability of atomic nuclei and how they are formed.

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. The findings suggest CSL-hosting chiral helimagnets as promising materials for future communication technologies.
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.

World’s first LED light from rice husks
11 Apr 2022
Milling rice to separate the grain from the husks, produces about 100 million tons of rice husk waste globally each year. Scientists searching for a scalable method to fabricate quantum dots have developed a way to recycle rice husks to create the first silicon quantum dot LED light. Their new method transforms agricultural waste into state-of-the-art light-emitting diodes in a low-cost, environmentally friendly way.
