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.

Researchers from Osaka University expanded the synthetic toolkit for preparing valuable chemical precursors from renewable feedstocks. They used microwave irradiation to dramatically improve the selectivity of the formose reaction, forming a simple six- and seven-carbon mixture that can be readily purified. These findings will help the chemicals industry minimize the use of fossil resources and improve the sustainability of manufacturing processes.

Osaka Metropolitan University scientists have succeeded in synthesizing fumaric acid, a raw material for plastics, from CO2 powered by solar energy—for the first time. Typically, fumaric acid is synthesized from petroleum as a raw material to make polybutylene succinate, a biodegradable plastic, but this research shows that it can be synthesized from CO2 and biomass-derived compounds using renewable energy.

Osaka Metropolitan University scientists have created a novel thermoresponsive polymer by adding divalent cations to polymers and water solvents. They also succeeded in controlling thermoresponsive properties by changing the type and mixing ratio of ionic species. This new polymer type is expected to be applied as an analytical reagent for ion-sensing devices and as a material for drug delivery systems.

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.

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.

Researchers at Kanazawa University report in Science Advances a new method for distinguishing between enantiomers, molecules that are mirror images of each other. The procedure, relevant for the pharmaceutical industry, involves the chemical reaction of target enantiomers with color indicator compounds consisting of one-handed helical polymers, leading to solutions showing different colors in specific solvents between the enantiomers.

When it comes to cancer, clarity is key. The ability to visualize cancerous tumors and metastatic tissue three dimensionally (3D) can help clinicians diagnose the precise type and stage of cancer, while also informing the best treatment methods. To obtain an even clearer tissue for imaging, a research team based in Japan has tested the effectiveness of specialized hydrogels. Acting as a 3D molecular network, these hydrogels can rapidly remove fats from tissues, which are a factor in tissue opacification, without losing their structure. The material is used in several biomedical devices, including contact lenses.
