A team of chemists at Southern University of Science and Technology, working with a colleague from Zhejiang University, both in China, has engineered a metal–ligand complex that incorporates a reactive pocket to pre-organize prochiral substrates. Their paper is published in the journal Science.
Carbon radicals are being used as an intermediate in a variety of synthetic transformations. Because they have just one electron, they tend to be highly reactive, allowing for speedy reactions with little energy release.
Unfortunately, when working with prochiral substrates, where three different groups are attached to a single radical center, the ability to control the reaction becomes untenable. Prior research has shown that the underlying cause of these difficulties lies with the differences inherent in the alkyl group, where non-stereoselective reactions tend to dominate.
Over the past decades, many countries worldwide have been trying to gradually transform their energy systems, with the aim of reducing carbon emissions and mitigating the adverse effects of climate change. Hydrogen and carbon dioxide (CO2) transport networks, infrastructures designed to transport hydrogen gas and captured CO2, could support the shift towards climate-neutral energy systems.
Researchers at Technical University Berlin carried out a study aimed at better understanding the extent to which hydrogen and CO2 transport networks could contribute to the future de-carbonization of the European energy system. Their paper, published in Nature Energy, suggests that both these types of networks could play a key role in establishing a sustainable and clean European energy system.
“In our view, we are envisioning a climate-friendly economy which relies as little as possible on fossil fuels and respects socio-economic considerations,” Fabian Hofmann, first author of the paper, told Tech Xplore.
Aluminum alloys are well-known for their low weight and corrosion resistance, making them ideal candidates for applications in a low-carbon economy—from lightweight automobiles to tanks for storing green hydrogen. However, their widespread application is limited by a key challenge: they suffer from embrittlement leading to cracking and failure when exposed to hydrogen. Until now, alloys resistant to hydrogen embrittlement were rather soft, limiting their application in hydrogen-related technologies that require high strength.
Now, researchers from the Max Planck Institute for Sustainable Materials (MPI-SusMat) in Germany, together with partners from China and Japan, have developed a new alloy design strategy that overcomes this dilemma. Their approach enables both exceptional strength and superior resistance to hydrogen embrittlement (HE), paving the way for safer and more efficient aluminum components in the hydrogen economy. They have published their results in the journal Nature.
To combat climate change and achieve a climate-neutral industry, carbon emissions must be drastically reduced. A key part of this transition is replacing carbon-based energy carriers with electricity, particularly in transport and industrial applications. However, this shift heavily depends on nickel, a critical material used in batteries and stainless steel.
