Synthesis of fumaric acid by a new method of artificial photosynthesis, using sunlight

30-Jan-2023

In recent years, environmental problems caused by global warming have become more apparent due to greenhouse gases such as CO2. In natural photosynthesis, CO2 is not reduced directly, but is bound to organic compounds which are converted to glucose or starch. Mimicking this, artificial ...

Saved seconds add up to hours over multiple measurements

10-Jan-2023

How can the component elements of an unknown material, such as a meteorite, be determined? X-ray fluorescence analysis can be used to identify an abundance of elements, by irradiating samples with X-rays and analyzing the spectrum they emit and can detect many elements simultaneously. For this ...

Technology sequesters CO₂ emissions

31-Aug-2022

In plants, natural photosynthesis binds carbon dioxide (CO2­) to organic compounds, which can then be converted into glucose or starch. These useful molecules can be sequestered, storing the carbon in a solid form. Artificial photosynthesis mimics this process by reducing the greenhouse gas CO2– ...

A clever new method for observing metal-organic frameworks and guest molecule interactions, using real-time polarized infrared spectroscopy

18-May-2022

Most people don’t think about how molecules fit in the ultra-small spaces between other molecules, but that is what Professor Masahide Takahashi’s research team do every day at Osaka Metropolitan University. They study metal-organic frameworks (MOF), composed of modularly arranged metal ions and ...
