Osaka Metropolitan University researchers have successfully synthesized fumarate (fumaric acid), a raw material for unsaturated polyester resin, by combining carbon dioxide (CO2) with pyruvate (derived from biomass), using two biocatalysts: malate dehydrogenase and fumarase. Fumarate is currently used to make biodegradable plastic like polybutylene succinate from petroleum. However, this research has enabled the synthesis of fumarate without petroleum, consuming only CO2 and biomass-derived pyruvate.

Osaka Metropolitan University researchers have clarified the first suitable computational conditions for Adiabatic State Preparation (ASP) executable on a quantum computer, a method that can improve the accuracy of calculating atomic and molecular wave functions. ASP is thought to be one of the leading methods for efficiently preparing correlated wave functions of molecules with complex electronic structures, but the specific conditions required for the calculations have not been thoroughly investigated so far. 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.

Nonthermal plasma (NTP) is used to activate CO2 molecules for hydrogenation into alternative fuels at low temperatures, also enabling the conversion of renewable electricity to chemical energy. Researchers from Tokyo Tech combined experimental and computational methods to investigate the hydrogenation pathway of NTP-promoted CO2 on the surface of Pd2Ga/SiO2 catalysts. The mechanistic insights from their study can help improve the efficiency of catalytic hydrogenation of CO2 and allows the engineers to design new concept catalysts.

Solar panels often get a bad rap for spoiling the appearance of homes and businesses. Yet, a research group has fabricated a highly transparent solar cell with a 2D atomic sheet. These near-invisible solar cells achieved an average visible transparency of 79%, meaning they can, in theory, be placed everywhere—building windows, the front panel of cars, and even human skin.

MOF nanosheet creation on the surface of water
28 Jun 2022
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.

Atomic force microscopy (AFM) allows to visualize the dynamics of single biomolecules during their functional activity. All observations are, however, restricted to regions accessible by a fairly big probing tip during scanning. Hence, AFM images only the biomolecular surface with limited spatial resolution, missing important information required for a detailed understanding of the observed phenomena.

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.
