April 19, 2024 | Bastian Oberhausen graduated
Polymer-based self-healing nanocomposites are a promising class of materials which are able to contribute to saving resources and thus to a more sustainable future. In his thesis, Bastian Oberhausen examined the integration of superparamagnetic iron oxide nanoparticles as cross-links in polymers. The resulting nanocomposites show a self-healing behavior after damage under the influence of an alternating magnetic field. Today will be the thesis defense of his dissertation.

April 8, 2024 | How are dielectric membranes influenced by chemical processing?
Dielectric elastomer transformers (DETs), i.e. highly extensible dielectric membranes between two flexible electrodes enable the development of sensors, actuators and generator systems. The performance of DETs substantially depends on the material properties of the dielectric and the electrodes, as well as of the production process. Producing electrodes via silkscreen printing requires considerable amounts of solvents to regulate the viscosity of the printing material, which might impact the properties of the DETs. This effect has hardly been researched as of yet. In a joint project, the working groups of Prof. Gianlucca Rizzello, Prof. Paul Motzki and Prof. Stefan Seelecke examined the influence of different solvents on a DET. Results show a significant influence of the used solvent on the electrical resistance of the electrodes, but does not change the disruptive strength of the pure dielectric. These new findings provide systematic guidelines for the selection of solvents in the production process of DET-electrodes. The study has been published today in the journal Advanced Engineering Materials (see: https://onlinelibrary.wiley.com/doi/10.1002/adem.202301736).

28.04.2023 | Organic groups have a major influence on the formation of silsesquioxanes with special properties
In a publication accepted today in the Journal of Sol-Gel Science and Technology, Svenja Pohl shows in a systematic comparative study that the organic residue on the silicon atoms of silsesquioxane polymers has a significant influence on the degree of condensation of the polymers. This is also decisive for the softening range of the polymers. The study contributes to the understanding of how the properties in so-called "melting gels", which exhibit thermoplastic behavior in a certain temperature range, can be influenced by the chemical composition (see https://link.springer.com/article/10.1007/s10971-023-06126-6).

March 8, 2023 | Inorganic-organic hybrid materials show exceptional electrochemical properties
So-called luminescent solar concentrators make it possible to capture diffuse sunlight in order to use it to generate electricity. Solar radiation is captured by colored plastic panels, and at the edges, microsolar cells convert the resulting light into electricity. In cooperation with the research group of Prof. Andrea Pucci at the University of Pisa, a material developed at the UdS was used for the first time for flexible solar concentrators. The corresponding article was published in Polymer Chemistry (see: https://pubs.rsc.org/en/content/articlelanding/2023/py/d2py01428a). For further information, see this press release: https://www.uni-saarland.de/aktuell/chemiker-solarzellen-farbig-26511.html and this TV report:https://www.sr-mediathek.de/index.php?seite=7&id=127114&startvid=10.

Feb 10, 2023 | Mechanochemistry allows a fast and energy-efficient production of black metal oxides
Metal oxides are usually colourless solids. When we are able to reduce the metal ions successfully, so-called black metal ions will result. These often have extraordinary electronic and catalytic properties. In a study of Anna Michaely in co-operation with a team of other authors, they succeeded to produce black titanium oxide (TiO₂) and black niobium oxide (Nb₂O₅) after just 10 min. by a simple chemical conversion in a ball mill. These black metal oxides showed the expected changes in their electronic properties and for the titanium dioxide, a significantly higher activity in its photocatalytic properties could be proven. The study was published in Chemistry – A European Journal (https://chemistry-europe.onlinelibrary.wiley.com/doi/abs/10.1002/chem.202300223)

They noticed significant differences between the preparations which can have an impact on the biological uptake of silicon. The study was published in Solids (https://www.mdpi.com/2673-6497/4/1/1)

Dec 21, 2022 | Inorganic-organic hybrid materials show extraordinary electrochemical properties
In a co-operation with the working group of Prof. Volker Presser of INM (Leibniz-Institut für Neue Materialien), inorganic-organic hybrid materials were produced containing both redox active inorganic and referring organic components. In co-operation with other scientists, Mana Abdirahman Mohamed and Stefanie Arnold were able to continuously synthesize these materials in a wet-chemical process and to characterize them electrochemically. The materials received represent a new category of electrode materials for lithium-ion-batteries. They can be synthesized in a so-called Microjet-Reactor by an efficient scalable precipitation reaction at room temperature, using cost-effective reactants. The study was published in ChemSusChem (https://chemistry-europe.onlinelibrary.wiley.com/doi/10.1002/cssc.202202213).

May 26, 2022 | PhD position in the field of Polysiloxane-based inorganic-organic hybrid materials

May 19, 2022 | New thermally stable one-component crosslinking silicones with high refractive index
Silicones with a high refractive index play an important role in many optical applications. In a recently published paper, we were able to show that polycyclic aromatic systems can significantly increase the refractive index as substituents on the silicon atoms in the silicones. Max Briesenick used a synthesis strategy optimized in our group, which allows the silicones to be crosslinked purely thermally without a catalyst. The crosslinked resins exhibited refractive indices above 1.6, very high optical transparency, and thermal stabilities up to 470 °C, and may thus be of interest for high-temperature optical applications. The study was published in Macromolecules (https://pubs.acs.org/doi/full/10.1021/acs.macromol.2c00265).

September 21, 2021 | Stable Organosilanoles – the slightly different homologs of the alcohols
Organosilanoles, the silicium homologs of the alcohols, typically are non-isolable molecules and show a high tendency to condensate to oligomeric or polymeric structures.  Only under very specific steric and electronic conditions in the silicon atom, they are known as stable, isolable molecules. Jan-Falk Kannengießer synthesized a number of acrylic-substituted representatives of this compound class by hydrolysis of the alkoxy or chlorine compounds. In the solid state, the products received show strong hydrogen bonds with different structural motifs. The study was published in Chemistry - A European Journal (https://chemistry-europe.onlinelibrary.wiley.com/doi/abs/10.1002/chem.202102729)

August 14, 2021 | Fluorescent SiO2-Particles – connection makes the difference
Fluorescent nanoparticles are important analysis instruments, especially for biological applications. A mainly used compound class in this field are SiO2-nanoparticles with embedded fluorescent pigments. Such particles are easily accessible and often used. In a recent study, Nadja Klippel showed together with Prof. Gregor Jung, that the connection of the pigments to the particle nucleus is important for their stability. Here, different connection mechanisms of fluorescent xanthene pigments with 30-40nm-sized silica-nanoparticles were examined and compared. Systematic leaching studies over a period of up to 4 days showed, that the covalent connection of the pigments ist essential for the fluorescence stability, as pigments solely connected by physical interaction tend to leach out of porous silica-networks. Coating the silica particles with hydrophobic or hydrophilic protective layers led to a better retention of solely physisorbed pigments and provides the opportunity to adjust the particles to the polarity of the medium. The study was published in the Journal of Sol-Gel Science and Technology (https://link.springer.com/article/10.1007%2Fs10971-021-05578-y).

August 12, 2021 | Polysiloxanes with high refraction index
Polycyclic aromatic hydrocarbones as substituents in polysiloxanes, known as silicones, can increase the refraction index to values up to 1.63. Conventional commercially available polysiloxanes only have refraction indices under 1.5. Dennis Meier synthesized the polymers from phenanthrenyl-substituted monomers by polycondensation reactions with other dialkoxysilanes.  The resulting polymers were thermally cross-linked and thus, polysiloxane resins with high refraction index, high optical transparence and high thermal stability of up to 420°C could be obtained. Such materials are mainly used for optical applications. In addition to the publication in the Journal of Polymer Science ( onlinelibrary.wiley.com/doi/full/10.1002/pol.20210316), the materials were also patented.

August 5, 2021 | Self-healing of nanocomposites by induction heating
Self-healing materials provide an important opportunity to increase the longevity of objects. They are therefore able to contribute to saving resources in the use of raw materials and thus to a more sustainable material development. In a recent study, Bastian Oberhausen showed that embedding superparamagnetic nanoparticles into a polymer matrix allows to induce self-healing by induction heating.  The particle surface was modified with positively charged organic groups and the polymer matrix contained the referring anionic charges. After cutting the sample apart, the parts could be merged again by induction heating and the sample showed its original properties. The study was published in the Journal Nanoscale Advances (https://pubs.rsc.org/en/content/articlelanding/2021/na/d1na00417d).

April 13, 2021 | New hybrid material shows thermoplastic behaviour
Our study on polysilsesquioxane material compounded by using a simple polymerisation method was published today. Under specific conditions, we were able to produce a material showing thermoplastic behaviour. This is known for the usual organic polymers but not for silicone-like structures. While the material can be fused at 110 °C, it is solid at room temperature. There are some other properties of these systems that may be of interest for technological use: they are highly transparent and low-level permeable for gas molecules like oxygen or water vapour. They could be replacing the conventional silicones in optical applications and save resources in the process, as they do not need a platinum catalyst for cross-linking. In a study in the journal Macromolecules we were able to correlate the properties of this material with its structure. (https://pubs.acs.org/doi/abs/10.1021/acs.macromol.1c00310)

February 16, 2021 | Moulding super-hydrophobic surfaces of the carob tree
For billions of years, flora and fauna were creating surface structures that allow survival under special environmental conditions. Many of these microscopic surface structures are beneficial for technological use, e.g. for adhesion or light reflection. However, moulding these structures is difficult because of their microscopic refinement and their surface chemistry. In an international research project with research groups from Portugal and Sweden, we were able to mould finest structures by special polymer combinations and to transfer them to a new form. The polymer properties like adhesion and mechanical properties had to be balanced accurately. The article has been published in the Langmuir journal. (https://pubs.acs.org/doi/10.1021/acs.langmuir.0c02806).

A publication by Siyang He published today shows that fluorescent dyes can be attached to surfaces of iron oxide nanoparticles and that it is possible to release the dyes from the surface by temperature-dependent switching. At temperatures above 130°C, the bond between the dye and the surface is cleaved and the dye can diffuse into the environment. On cooling, the bond to the surface is formed again. This process can be carried out many times. Attaching the dye to magnetic nanoparticles opens up the possibility of magnetically separating the particles after dye separation. This allows the particles to be used as transport vehicles for various substances. The study was published in the open access journal Molecules (https://www.mdpi.com/1420-3049/26/4/877/htm).

December 21, 2020 | Guido Kickelbick Editor in Charge for new Paper Solid

12.12.2020 | Distribution of nanoparticles in nanocomposites depending on chemical surface functionalisation
In cooperation with two partners from Austria at Vienna University and the TU Wien, we were able to systematically prove a significant influence of the interaction between the surface of nanoparticles and the polymer matrix on the homogeneous distribution of the particles in the matrix. Here, chemical interactions and the morphology of the particles are playing a significant role. The study has been published in the Open Acces Paper Surfaces (https://www.mdpi.com/2571-9637/3/4/44).

July 12, 2020 | Preparation of aluminides from nanoparticles
Can ruthenium and nickel aluminides be prepared from nanoparticles and what is the advantage compared to other synthesis methods? Thomas Klein shows in two articles published in co-operation with the Mücklich working group how intelligent chemical synthesis allows the preparation of the desired aluminides by so-called self-sustaining reactions. Aluminides are intermetallic compounds with special mechanical and thermal properties. The materials were produced by using a new synthesis concept. A notable aspect is the considerable reduction of the ignition temperature for the self-sustaining reactions by a maximum use of the nanometer scale.  The studies have been published in two articles in Intermetallics. Titles: „Al and Ru nanoparticles as precursors for Ru–Al intermetallics“ https://doi.org/10.1016/j.intermet.2020.106851and „Al and Ni nanoparticles as precursors for Ni aluminides“ https://doi.org/10.1016/j.intermet.2020.106839

New patent in cooperation with BASF
In cooperation with BASF, we were able to patent a new material which enables the stable embedding of organic fluorescent pigments -used as e.g. conversion pigments in LEDs- into a polysiloxane matrix. This allows the production of rare earth-reduced or - free LEDs. For the patents, please see the following patent numbers: WO2019137975A2;WO2019137975A3;TW201938695A

January 18, 2019: New material for the encapsulation of LEDs
Together with industrial partners (Osram, BASF), our working group developed a new encapsulation material allowing to produce less expensive long-life LEDs without rare earths. Two patents have been filed on this subject. 
The new material is based on a special, freely configurable silicone for different requirements. The most important parameters are fulfilled: the material is thermally resistant, highly transparent and easy to process. Besides, the material is saving resources: in conventional material, platinum is used as a catalyst for the interlacing of liquid precursors, whereas the new material can completely do without.

July 1, 2011: Saarland University participates in a BMWi project about nuclear waste disposal research
The search for a repository to store high-level radioactive waste for a very long time of over 100,000 years is one of the most urgent tasks facing scientists and politicians today. In the framework of joint projects analytical methods like sorption/desorption or migration experiments for radionuclides and other toxic metals as well as specially developed analytical tools as for example 2D-NMR or CE-ICP-MS hyphenation are utilised to study the mobility of radioactive heavy metals in a potential host rock material (e.g. clay or salt). The findings of this research are very important in the context of a long time risk assessment of a future disposal site for high level radioactive waste. The Federal Ministry of Economics and Technology (BMWi) financially supports the research project at Saarland University for three more years with 583,000 euro. Since August 2006, over 1.27 million euros of third-party funds could be acquired by PD Dr. Ralf Kautenburger, Prof. Dr. H.P. Beck und Prof. Dr. G. Kickelbick, scientists belonging to the Chemistry Department.

July 1, 2011: DFG grants project of chemists and engineers about self healing nanocomposites
The research groups of Prof. Wenz, Prof. Stommel and Prof Kickelbick investigate in a joint project within the framework of the DFG priority program "Design and Generic Principles of Self-healing Materials" (DFG SPP 1568) the possibilities to use nanocomposites on the basis of cellulose and inorganic nanoparticles as self-healing materials. This means that, e.g. scratches in the polymeric material can be stopped and healed by thermoreversible crosslinking.

July 1, 2011: New X-ray powder diffractometer granted
A new high-capacity powder diffractometer was granted.
