Researchers from the Department of Atomically Resolved Dynamics of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg, the University of Potsdam (both in Germany) and the University of Toronto (Canada) have pieced together a detailed time-lapse movie revealing all the major steps during the catalytic cycle of an enzyme. Surprisingly, the communication between the protein units is accomplished via a water-network akin to a string telephone. This communication is aligned with a ‘breathing’ motion, that is the expansion and contraction of the protein.

Scientists at Münster University investigate cells using dual-beam laser mass spectrometry:Cells are the basic building blocks of life. The chemical composition of cells can be determined by mass spectrometry. Scientists at the University of Münster present a method which has improved the spatial resolution of “MALDI” mass spectrometry by around one-thousandth of a millimetre. The results have been published in "Nature Methods".

Within the scope of the project PoSiBat (funding reference 100275833), Fraunhofer FEP scientists were able to develop a non-toxic and efficient manufacturing process for porous silicon layers. The results of the recently completed project will be presented at the Thin Film Technology for Energy Systems workshop at V 2019 and at the Fraunhofer FEP booth No. 22 (October 8 –10, 2019, in Dresden, Germany). Lithium-ion batteries are well established due to their good properties. They have a higher energy density than other batteries. Therefore, they are used in cameras, watches, mobile devices and especially for electric vehicles. However, from a technical point of view they still offer a high potential for improving and optimizing of battery cells.

The recording of images of the human brain and its therapy in neurodegenerative diseases is still a major challenge in current medical research. The so-called blood-brain barrier, a kind of filter system of the body between the blood system and the central nervous system, constrains the supply of drugs or contrast media that would allow therapy and image acquisition. Scientists at the Max Planck Institute for Polymer Research (MPI-P) have now produced tiny diamonds, so-called "nanodiamonds", which could serve as a platform for both the therapy and diagnosis of brain diseases.

Publication in Scientific Reports
Carbon nanoparticles are a promising tool for biomedical applications, for example for targeted transportation of biologically active compounds into cells. A team of researchers from the Physics, Medicine and Chemistry departments at Heinrich Heine University Düsseldorf (HHU) has now examined whether these particles are potentially dangerous for the organism and how cells cope with them once they have been incorporated. The findings of the interdisciplinary study have just been published in the journal Scientific Reports.

IST Austria scientists determine the first structure of a cell’s rotary engine using state-of-art microscopy. Cells rely on protein complexes known as ATP synthases or ATPases for their energy needs – adenosine triphosphate (ATP) molecules power most of the processes sustaining life. Structural biologist Professor Leonid Sazanov and his research group from the Institute of Science and Technology Austria (IST Austria) in Klosterneuburg, Austria have now determined the first atomic structure of the representative of the V/A-ATPase family, filling in the gap in the evolutionary tree of these essential molecular machines. These results obtained using the latest cryo-electron microscopy methods revealed a turbine or water mill similar structure of the enzyme and have now been published in the journal Science.

Programmable structural dynamics successful for first time in self-organizing fiber structures.
Cells assemble dynamically: their components are continuously exchanging and being replaced. This enables the structures to adapt easily to different situations, and by rearranging the components to respond to stimuli faster, to renew or to form just on demand. The microtubules, a scaffold structure made of protein fibers that can be found in the cytoplasm of the cells of algae, plants, fungi, animals and humans, are one such dynamic mesh. Because of their self-organizing structure, these fibers constantly form and degrade at the same time, thereby actively supporting the cell in complex tasks such as cell division or locomotion. The fibers require energy to form and maintain such dynamic states.

They look like interlocking egg cups, but a hen's egg is 100,000 times as thick as one of the miniature cups: Scientists at the Center for Nanointegration (CENIDE) at the University of Duisburg-Essen (UDE) have made polymers to form themselves into tiny cups on their own. They could, for example, be used to remove oil residues from water. The scientists have published their results in the journal "Angewandte Chemie".

Chemists at the Technical University of Munich (TUM) have developed an efficient water splitting catalyst as part of a collaborative international research effort. The catalyst comprises a double-helix semiconductor structure encased in carbon nitride. It is perfect for producing hydrogen economically and sustainably. An international team led by TUM chemist Tom Nilges and engineer Karthik Shankar from the University of Alberta have now found a stable yet flexible semiconductor structure that splits water much more efficiently than was previously possible.

The use of potassium bromide in the production of graphene on a copper surface can lead to better results. When potassium bromide molecules arrange themselves between graphene and copper, it results in electronic decoupling. This alters the electrical properties of the graphene produced, bringing them closer to pure graphene, as reported by physicists from the universities of Basel, Modena and Munich in the journal ACS Nano.

Radioactive antibodies that target cancer cells are used for medical diagnostics with PET imaging or for targeted radioimmunotherapy. Researchers from the University of Zurich have created a new method for radiolabelling antibodies using UV light. In less than 15 minutes, the proteins are ready-to-use for cancer imaging or therapy. Radioactive antibodies are used in nuclear medicine as imaging agents for positron emission tomography (PET) – an imaging technique that improves cancer diagnosis and monitoring of chemotherapy. Radioactive drugs can also be designed to kill tumors by delivering a radioactive payload specifically to the cancer cells. This treatment is called targeted radioimmunotherapy.

The human eye is particularly sensitive to green, but less sensitive to blue and red. Chemists led by Hubert Huppertz at the University of Innsbruck have now developed a new red phosphor whose light is well perceived by the eye. This increases the light yield of white LEDs by around one sixth, which can significantly improve the energy efficiency of lighting systems.

Human cells have a sophisticated regulatory system at their disposal: labeling proteins with the small molecule ubiquitin. In a first, a team from the Technical University of Munich (TUM) has succeeded in marking proteins with ubiquitin in a targeted manner, in test tubes as well as in living cells. The procedure opens the door to exploring the inner workings of this vital regulatory system.

Scientists at the University of Bremen have now developed a three-dimensional protein structure in the laboratory that could help to heal wounds in the future. It is conceivable that one day this network could be produced as a kind of “biological bandage” from the blood of the person who will use it. The development is now patent pending.

Visitors will have the opportunity to experience the bioeconomy’s latest product innovations and research findings at Hannover Messe. Other types of events, such as the International Bioeconomy Conference, promote the establishment of international partnerships and drive economic change towards a bioeconomy.
Nineteen research projects currently being funded by the Federal Ministry of Education and Research (BMBF) and the Federal Ministry of Food and Agriculture (BMEL) will be presented at the joint stand “Showcasing the Bioeconomy” at Hannover Messe 2019. We are co-exhibitors with our cluster partners.
