Sustainable Chemistry students print their way to new and powerful supercapacitors
3D CAD files included in scientific publication Students at the University of Amsterdam’s Research Priority Area Sustainable Chemistry have tripled the specific capacitance of nitrogen-doped carbons: new materials with potential applications in fast energy storage (e.g. for regenerative breaking or fast charging of cellphones). Their experiments required new pieces of equipment which were designed and produced in the lab using 3D printing.

Amsterdam chemists synthesize molecular pretzels
Towards synthetic lasso peptides
Chemists at the University of Amsterdam’s Van ‘t Hoff Institute for Molecular Sciences have discovered a new class of molecules. This week they report in Nature Communications on their synthesis method leading to ‘quasi[1]catenanes’: pretzel-like molecules consisting of two molecular rings ‘oppositely’ coupled at a central carbon atom. The discovery is an important step towards synthesis of lasso peptides; new molecules with a potential use as medicines.

Enzymatic dissolution of lignin in water
Researchers of the University of Amsterdam’s Research Priority Area Sustainable Chemistry have developed a new approach to dissolving lignin in water. They used a simple and effective enzymatic process under ambient conditions, paving the way towards industrial application of this abundant natural resource of aromatics. The results, published online in ‘ChemSusChem’ , were recently featured in ‘Chemical & Engineering News (C&EN)’.

New cobalt catalyst for highly selective synthesis of cyclic amines
Very Important Paper in ‘Chemistry, a European Journal’
Researchers of the University of Amsterdam’s Van ‘t Hoff Institute for Molecular Sciences (HIMS) have developed a cobalt-based catalyst for the direct synthesis of various N-heterocycles from aliphatic azides by means of intramolecular ring-closing C−H bond amination. Their result has just been published online by ‘Chemistry, a European Journal’, as a Very Important Paper.

Record breaking reactivity of new iron catalyst for synthesis of cyclic amines
Publication in Journal of the American Chemical Society
Chemists at the University of Amsterdam’s Van ‘t Hoff Institute for Molecular Sciences (HIMS) have developed a very efficient way to selectively produce amines, which are prevalent as a functional group in both bulk and fine chemicals. Using a catalyst based on the earth-abundant element iron, they established a record breaking reactivity in preparing cyclic amines via an atom-efficient C-H amination protocol, inserting a nitrogen atom into an unactivated C-H bond.

Smart materials design leads to new dual-mode humidity sensing
Dr Stefania Tanase Grecea and co-researchers at the University of Amsterdam’s Research Priority Area Sustainable Chemistry have demonstrated the first dual-mode humidity sensing material. Based on a lanthanide-based metal organic framework it can sense water both optically and electrically. The research was recently published in the journal Chemical Communications.

Amsterdam aquatolide synthesis enables Science publication on NMR
Aquatolide produced in the Hiemstra lab serves as testing compound for new robust NMR analysis
A sample of the natural compound aquatolide, synthesized in the Synthetic Organic Chemistry laboratory of professor Henk Hiemstra at the Van ‘t Hoff Institute for Molecular Sciences, played a pivotal role in American NMR research published in this week’s issue of Science.
