Osaka Metropolitan University scientists elucidated the molecular structure of anionic Pt(0) complexes for the first time in collaboration with co-researchers at Paul Sabatier University - Toulouse III. The key to success is the stabilization of anionic Pt(0) complexes (which are usually unstable owing to their electron-donating nature) by the electron-accepting properties of boron compounds. The results of this research allow us to elucidate the properties and functions of highly active chemical species and provide new guidelines for their creation. The research is expected to lead to the development of innovative catalytic reactions mediated by these chemical species.
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.

Transport relies heavily on steel. But steel is heavy, and scientists are turning to alternatives to lessen the transportation industry’s carbon emissions. Magnesium alloys are one such alternative. But developing bonding technology that bonds magnesium alloys with structural steels has been severely limited because magnesium and iron are immiscible. Yet, a research group from Tohoku University has established a dealloying bonding technology that obtains a strong mechanical bond between iron and magnesium.

We typically think of robots as metal objects, filled with motors and circuits. But the field of molecular robotics is starting to change that. Like the formation of complex living organisms, molecular robots derive their form and functionality from assembled molecules stored in a single unit, i.e., a body. Yet manufacturing this body at the microscopic level is an engineering nightmare. Now, a Tohoku University team has created a simple workaround.

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. The phosphorylated yeast is expected to be utilized as a material for recovering useful metals and removing toxic metals, thereby contributing to the realization of a metal resource-circulating society.

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.
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.
