CO₂ recycling and efficient drug development – tackling two problems with one reaction
Work marks an especially large breakthrough, since CO₂ is used to carry out a traditionally difficult type of transformation with unprecedented efficiency
24-Feb-2022
Using electricity, a new method offers the possibility of recycling CO2 while also performing a notoriously difficult reaction, producing compounds potentially useful for drug development. Scientists at the Institute for Chemical Reaction Design and Discovery (ICReDD) in Hokkaido University have ...
A new tool to create chemical complexity from fatty acids
A new catalyst design enables unprecedented control over the modification of fatty acid derivatives that opens the door to creating useful substances in a green and efficient manner
25-Aug-2020
Hokkaido University WPI-ICReDD researchers developed a modular catalyst that can accurately modify fatty acid derivatives in a hitherto inaccessible position. This enables the efficient production of valuable compounds from a renewable bioresource, whereas before we had to either rely on ...
Boosting solid state chemical reactions
13-Feb-2019
Adding olefin enables efficient solvent-free cross-coupling reactions, leading to environmentally friendly syntheses of a wide range of organic materials. A cross coupling reaction is typically performed in an organic solvent and leads to the production of a large amount of solvent waste, which ...
Repeated interferon stimulation creates innate immune memory
29-Oct-2018
The innate immune system may be able to be trained to react to viral infections more efficiently by repeated exposure to anti-viral signaling molecules. Mammalian cells seem to be able to memorize anti-viral stimulation at the level of DNA-packaging molecules, enabling faster and greater ...
New record set for carbon-carbon single bond length
13-Mar-2018
A stable organic compound has been synthesized with a record length for the bond between its carbon atoms, exceeding the assumed limit. Hokkaido University researchers have synthesized an organic compound with a longer bond between carbon atoms than ever before - exceeding the assumed limit for ...
When gold turns invisible
Application in bioimaging and security inks possible
02-Jun-2017
A gold compound shifts from a visible fluorescence to emitting infrared when ground - a big shift with potential applications in bioimaging and security inks. Some materials luminesce, changing their color and intensity when under mechanical forces such as grinding or rubbing. These luminescent ...
The gene of autumn colors
26-Oct-2016
In plants, the pigment chlorophyll plays a central role in photosynthesis: the process of converting sunlight to energy. This process involves creating a flow of electrons by removing one from a molecule and transferring it to another. The first step happens when an electron is transferred from ...
Making electronics safer with perovskites
17-Mar-2016
Ceramic capacitors are used in a wide variety of electronics, ranging from computers and mobile phones to telecommunications transmitter stations and high voltage laser power supplies. Capacitors act, in a way, like batteries. They are "dielectric" - they act as an electronic insulator in which ...
