The comprehensive reduction of clinically relevant antibiotic resistances from treated wastewater is the topic of the publication in NATURE Scientific Research, published by the Department of Microbiology/Molecular Biology under the direction of Prof. Thomas Schwartz. Oxidative and membrane based methods are compared in combination and subsequent microbiological risks are described.
An article on this topic was published in the FAZ of 3.4.2019, which also refers to the investigations of Prof. Dr. Thomas Schwartz, Department of Microbiology/Molecular Biology at the IFG. As part of a BMBF project, various municipal sewage treatments plants are being investigated for the presence of antibiotic-resistant bacteria and their distribution in the environment is being shown. By means of extended treatment processes it is possible to interrupt these distribution pathways. This is also demanded by the WHO and the UN Assembly.
An ideal material for photon harvesting must allow control of the exciton diffusion length and directionality. This is necessary in order to guide excitons to a reaction center, where their energy can drive a desired process. To reach this goal both of the following are required; short- and long-range structural order in the material and a detailed understanding of the excitonic transport. Here we present a strategy to realize crystalline chromophore assemblies with bespoke architecture.

New findings on the structure of catalysts and photocatalysts enable targeted further development of catalysts and photocatalysts - Three publications in the journal Angewandte Chemie
Researchers of Karlsruhe Institute of Technology (KIT) have made major progress in the production of two-dimensional polymer-based materials. To produce cloths from monomolecular threads, the scientists used SURMOFs, i.e. surface-mounted metal-organic frameworks, developed by KIT.
In the summer of 2016 a new project of the Institute of Functional Interfaces (IFG) of KIT and the Helmholtz Association of German Research Centers piqued the interest of Elmar Himmel, the mayor of the town of Malsch. The project "Prevention in construction" aims at prolonging the service life of infrastructure as bridges, streets, and buildings.
Researchers of Karlsruhe Institute of Technology (KIT) and Universität Hannover developed novel membranes, whose selectivity can be switched dynamically with the help of light. For this purpose, azobenzene molecules were integrated into membranes made of metal-organic frameworks (MOFs). Depending on the irradiation wavelength, these azobenzene units in the MOFs adopt a stretched or angular form. In this way, it is possible to dynamically adjust the permeability of the membrane and the separation factor of gases or liquids. The results are reported in Nature Communications. (DOI:10.1038/ncomms13872)
Medical implants often carry surface substrates that release active substances or to which biomolecules or cells can adhere better. However, degradable gas-phase coatings for degradable implants, such as surgical suture materials or scaffolds for tissue culturing, have been lacking so far. In the journal Angewandte Chemie, researchers of Karlsruhe Institute of Technology (under the aegis of Prof. Dr. Lahann) now present a polymer coating that is degraded in the body together with its carrier.
