Award for research on molecular spintronics

The materials scientist Dr. Wolfgang Wernsdorfer has received the 2012 Gutenberg Lecture Award worth €10,000. The award is given annually by the Graduate School Materials Science in Mainz (MAINZ) for special achievements in materials science.

This year, the Graduate School has chosen to honor Dr. Wolfgang Wernsdorfer, a physicist working in the field of molecular spintronics. "Dr. Wolfgang Wernsdorfer is one of the pioneers in the fields of single-molecule magnets and nanoparticle magnetism. He is taking highly innovative and promising pathways that will lead to the development of the microelectronics of the future," says Professor Dr. Mathias Kläui, who together with Professor Dr. Claudia Felser heads the MAINZ Graduate School at Johannes Gutenberg University Mainz (JGU).

The field of molecular spintronics involves the investigation of methods that can be used to manipulate the spin and charge in molecular structures on the nanoscale. Wernsdorfer's research group at the Institut Néel of CNRS Grenoble was among the first to discover and develop the molecular structures in which a quantum spin state can be measured and subsequently controlled.

Molecules were once generally considered to be non-magnetic, but Wernsdorfer and others have shown that this is not the case. Molecules can actually carry a significant magnetic moment and also exhibit a stable orientation similar to conventional magnets. These have come to be called 'single-molecule magnets,' and a single molecule made from only a few atoms can be seen as the smallest possible unit in which data can be stored in a structure. And this makes them particularly interesting not just in terms of potential applications: They not only have the classical properties of magnets, but have also been shown to exhibit quantum characteristics that are important when it comes to taking on new challenges, such as developing molecular data storage and quantum computers.

In addition to conducting measurements, Wernsdorfer's group in Grenoble also creates and develops new techniques, such as the nano-SQUID, which is sensitive enough to detect signals generated by only a few molecules. The research activities are undertaken in close interdisciplinary cooperation with synthetic chemists, solid-state physicists, and electrical engineers.

"From a scientific perspective, the work done by Wolfgang Wernsdorfer is extraordinarily relevant to MAINZ, since many of the related fields are being investigated at our facilities in Mainz and Kaiserslautern," explains Kläui. "Molecular spintronics represents the ideal combination of hard and soft materials and thus builds bridges between the various fields of research at the MAINZ Graduate School." Wernsdorfer has over 450 publications to his credit and has been awarded an ERC Advanced Grant, the Wohlfarth Lecture Prize, and the Agilent Europhysics Prize for his innovative work.

The Gutenberg Lecture Award represents a step towards closer cooperation. Wernsdorfer has already published with chemists and physicists from Johannes Gutenberg University Mainz, and this collaboration is to be stepped up in the future, particularly with regard to interdisciplinary projects that involve combination of organic materials and functional carbon allotropes with correlated spin systems. These hybrid structures made from soft and hard condensed materials exhibit innovative functions that in the long run could prove to be useful for memory, logic, and sensor systems.

Funding for the MAINZ Graduate School of Excellence was initially approved in the 2007 German Excellence Initiative. Recently, MAINZ proved successful with its renewal proposal in the second phase of the Excellence Initiative and was thus awarded funding for the next five years. This federal funding provides great recognition of the work undertaken by materials scientists in Mainz and of the support for young researchers at JGU. MAINZ combines work groups from Johannes Gutenberg University Mainz, the University of Kaiserslautern, and the Max Planck Institute for Polymer Research. The MAINZ Graduate School provides excellent education in the field of materials science to top-notch German and international doctoral candidates working in the natural sciences.

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
