In 2008 he celebrated his doctoral degree at the private university in Bremen, today he is a professor at the National Institute of Technology Karnataka in India: Sib Sankar Mal. This June and July, he will be back at Constructor University as part of his Humboldt Fellowship membership, conducting research together with his former PhD supervisor, Professor Ulrich Kortz.
Yemen, Pakistan, Germany – Hazim Saleem, a student at Constructor University in Bremen, had to adjust to new living conditions many times. However, there is one thing that remains constant: his love for chemistry. Now, Hazim has received the prestigious scholarship of the August Wilhelm von Hofmann Foundation of the German Chemical Society. He was also accepted for the Summer Undergraduate Research Program at New York University within the same week.
Seventeen years after first purchasing a single-crystal x-ray diffractometer, Constructor University in Bremen has recently upgraded to the latest technology. Chemistry Professor Dr. Ulrich Kortz successfully secured funding from the German Research Foundation (DFG) for the second time.
Together with two French colleagues, Professor Ulrich Kortz and Professor Werner Nau from Jacobs University Bremen form the CHAOPOM Consortium. Their bi-national research project “Chaotropic Polyoxometalates: From Fundamentals to Applications” is now being funded by the German Research Foundation (DFG) and its French counterpart, the Agence Nationale de la Recherche (ANR), with almost one million euros for the next three years.
Scientists at Jacobs University Bremen led by Ulrich Kortz, Professor of Chemistry, have achieved a breakthrough in the field of precious metal-oxo chemistry. For the first time, researchers have synthesized cationic, meaning positively charged, metal-oxo clusters based on palladium. They report on the synthesis and properties of these compounds in the renowned journal Angewandte Chemie, which classifies the article as a Hot Paper and thus as a particularly important contribution. The research project involved the working groups of four professors at Jacobs University.
They are as circular as a wheel and enclose a space with a diameter of about two nanometers. Researchers at Jacobs University Bremen led by Professor of Chemistry Ulrich Kortz want to use such a cavity of a molecule based on molybdenum and oxygen to be able to transport medically active substances into the body in a targeted manner. The three-year basic research project is funded by the German Research Foundation (DFG) with approximately 230,000 euros.
As a Christian, Sahar Khandan was not allowed to do her doctorate in Iran. Mahmoud El Cheikh Mahmoud grew up as a stateless Palestinian in Lebanon. Both are outstanding young scientists, both share a passion for chemistry. And both have now received a doctoral scholarship from the German Academic Exchange Service (DAAD) that will enable them to conduct their research at Jacobs University Bremen. “This is a wonderful achievement, they both deserve it for their passion and perseverance,” said chemistry professor Ulrich Kortz, to whose research group they both belong.
Precious metals such as platinum, palladium, gold, rhodium or iridium can be found in a variety of everyday products, for example in catalytic converters of cars, in mobile phones and laptops as well as in solar cells. They are particularly interesting for chemists because of their low reactivity with other elements. A team of researchers, led by Professor Ulrich Kortz at Jacobs University Bremen, now wants to develop a new class of materials containing precious metals and investigate their possible applications. “These materials will be very exciting not only for catalysis, but also for quantum computers and data storage,” says Prof. Kortz. The project is funded by the German Research Foundation with around 200,000 euros.

To make it to the final was his goal. “I’m really happy that it worked out,” says Jan Felix Schuster. The 19-year-old qualified for the national finals of the youth competition ‘Jugend forscht’ in Chemnitz from 16 to 19 May. He is the state champion of Bremen in the field of chemistry, and participating is more important than winning for him. “Getting to know the other projects and making new contacts is what I enjoy most about ‘Jugend forscht‘”.
Medicine? Yes! Engineering? Yes! But chemistry? Better not. “When people in Zimbabwe say that they want to study chemistry, most people ask: ‘What will you do with it?’ “, tells Lisa Tichagwa. “They normally suggest other subjects.” The 21-year-old nevertheless decided to study chemistry at Jacobs University Bremen. Now she has been awarded the August Wilhelm von Hofmann scholarship of the German Chemical Society (GDCh) for her outstanding academic achievements – and she feels satisfied with her choice. “The scholarship shows me that I made the right decision.”

It is stable and recyclable: a team of scientists from Jacobs University led by Ulrich Kortz, Professor of Chemistry, has developed a new class of materials in close cooperation with researchers from the Carl von Ossietzky University of Oldenburg and the Technical University of Munich. The compound based on the precious metal palladium paves the way for the full use of the entire class of discrete polyoxopalladates (POPs) as building blocks for 3D framework materials (MOFs). The project was funded by the German Research Foundation (DFG). The name of the new class of materials: POP-MOF, JUB-1.
The palladium(II)-containing 40-tungsto-4-arsenate(III) [Pd2Na2KAs4W40O140(H2O)]21– was synthesized by reaction of PdSO4 with the cryptate heteropolyanion [As4W40O140]28– in potassium acetate buffer. The title compound was characterized by single-crystal XRD, IR, TGA, and elemental analysis.
