Revolutionary nanovalve enables active control of single-molecule flows
01 May 2023
A joint research group at Osaka Metropolitan University has succeeded in regulating the flow of single molecules in solution by opening and closing the nanovalve mounted on the nanofluidic device by applying external pressure. The research group fabricated a device with a ribbon-like, thin, soft glass sheet on the top, and at the bottom a hard glass substrate having nanochannels and nanovalve seats. By applying external pressure to the soft glass sheet to open and close the valve, they succeeded in directly manipulating and controlling the flow of individual molecules in solution. They also observed an effect of fluorescence signal amplification when single fluorescent molecules are confined in the tiny nanospace inside the valve. The effect can be ascribed to the nanoconfinement, which suppresses the random motion of the molecules.

The Nobel prize winning physicist Niels Bohr once said, “An expert is a (person) that has made all the mistakes that can be made in a narrow field.” This idea that to master a skill we must learn from our mistakes and avoid making them in future has long been recognized; however, the brain mechanisms and pathways that control this ability have been poorly understood. We revealed a specific brain pathway that allows us to identify and learn from our mistakes to guide better decision-making in future. Our work is an important step towards understanding how the brain controls our daily choices and behavior. The identification of these cells as ‘mistake signalers’ may also help to guide new treatments for mental health conditions associated with impaired decision-making ability.

Overview of rare earth recovery using P-yeast
13 Apr 2023
A research group at Osaka Metropolitan University has succeeded in selectively recovering trace rare earth elements in synthetic seawater and environmental water, such as hot spring water, using baker’s yeast with a phosphate group added.

Osaka Metropolitan University scientists have developed a theory to experimentally determine differences in nuclear structure. Using this method to assess carbon and oxygen nuclei revealed that they contain more components in their cluster structure than in their shell structure. This enables visualization of nuclear structures without large-scale numerical calculations, which are expected to be applied to heavier nuclei in the future. This suggests that the method could be used to solve the ultimate question in nuclear physics: where did the elements we see around us come from?”

Osaka Metropolitan University scientists analyzed each element of the neutrino mass matrix belonging to leptons and showed theoretically that the intergenerational mixing of lepton flavors is large. Furthermore, by using the mathematics of random matrix theory, the research team was able to prove, as much as is possible at this stage, why the calculation of the squared difference of the neutrino masses are in close agreement with the experimental results in the case of the seesaw model with the random Dirac and Majorana matrices. The results of this research are expected to contribute to the further development of particle theory research, which largely remains a mystery.

Osaka Metropolitan University scientists have developed a process using artificial photosynthesis to successfully convert more than 60% of waste acetone into 3-hydroxybutyrate, a material used to manufacture biodegradable plastic. The results were obtained using low-concentration CO2, equivalent to exhaust gas, and powered by light equivalent to sunlight for 24 hours. The researchers expect that this innovative way of producing biodegradable plastic could not only reduce CO2 emissions but also provide a way of reusing laboratory and industrial waste acetone.

A group including Osaka Metropolitan University researchers discovered that the rhodopsin—a protein in the eye that detects light—of whale sharks has changed to efficiently detect blue light, which penetrates deep-sea water easily. The amino acid substitutions–one of which is counterintuitively associated with congenital stationary night blindness in humans—aid in detecting the low levels of light in the deep-sea. Although these changes make the whale shark rhodopsin less thermally stable the deep-sea temperature, allows their rhodopsin to keep working. This suggests that the unique adaptation evolved to function in the low-light low-temperature environment where whale sharks live.
Artificial metalloenzyme created with improved stereoselectivity
28 Mar 2023
A research group at Osaka Metropolitan University has succeeded in simply creating an artificial metalloenzyme with the common metal-binding motif 2-his-1-carboxylate, which is found in natural non-heme metalloenzymes. They created a library of 12 different proteins and screened the library and found that the H52A/H58E variant had the best stereoselectivity. It is expected that this research can be expanded to produce a variety of biocatalysts that work under mild conditions.
Rethinking near-infrared absorbing dye
24 Mar 2023
An Osaka Metropolitan University joint research group has discovered that near-infrared absorbing dyes, which had previously been considered to have closed-shell electronic structures, have an intermediate electronic structure, between closed- and open-shell structures. They also found that as the wavelength of near-infrared light that can be absorbed becomes longer the contribution of open-shell forms increases within the dye. These newly discovered characteristics are expected to be utilized to develop new near-infrared absorbing dyes that can absorb longer wavelength near-infrared light.

The FRCs were critical to the abdominal immune system as they regulated CXCL12 levels, a molecule necessary for lymphocyte recruitment from blood circulation. These insights can help develop novel treatments for intra-abdominal infections.

Researchers from SANKEN (The Institute of Scientific and Industrial Research), at Osaka University in collaboration with researchers from Imperial College London (UK) have improved the Faradaic efficiency of the nitrogen reduction reaction into ammonia by straightforward optimization of chemical process parameters.

These findings will also aid optimization of other analogous reactions, and thus help the chemicals industry optimize the sustainability of one of the most carbon-intensive reactions globally.
