Paderborn University

Michael Tiemann was appointed to the University of Paderborn in 2009 as W2 professor of Inorganic Chemistry. Since 2014 he is a chair holder (W3 professor). He declined a call for a chair at the Clausthal University of Technology (2014). Since 2011, he has also been a visiting professor at the Sino-German Technical Faculty (CDTF) of the Qingdao University of Science and Technology (QUST) in Qingdao (China); on the Paderborn side he coordinates the joint Bachelor's program "Chemistry" with the CDTF.

01.10.2002 - 30.09.2009

University of Giessen

From 2002 to 2009 Michael Tiemann was group leader at the Institute for Inorganic and Analytical Chemistry of the Justus Liebig University Giessen. In 2008, he received his habilitation and took over the Interim Chair of Inorganic Solid State Chemistry.

01.10.2001 - 30.09.2002

Abo Akademi

From 2001 to 2002, Michael Tiemann worked as a postdoctoral research assistant at the Institute of Physical Chemistry of the Åbo Akademi in Turku (Finland).

01.10.1997 - 30.09.2001

University of Hamburg

After studying chemistry (diploma), Michael Tiemann was a scientific coworker at the Institute of Inorganic and Applied Chemistry at the University of Hamburg from 1997 to 2001. He finished his PhD (Dr. rer. nat.) in 2001 at the chair of Prof. Armin Reller in the group of Dr. Michael Fröba (summa cum laude).

Examination of the evolution of iron oxide nanoparticles in flame spray pyrolysis by tailored in situ particle sampling techniques

In this report, a flame spray pyrolysis setup has been examined with various in situ extraction methods of particle samples along the flame axis. First, two precursor formulations leading to the formation of iron oxide nanoparticles were used in a standardized SpraySyn burner system, and the final particle outcome was characterized by a broad range of established powder characterization techniques (TEM/HRTEM, SAXS, XRD, BET). The characterization of the powder products evidenced that mostly homogeneous gas-to-particle conversion takes place when applying an acidic precursor solution, whereas the absence of the acid leads to a dominant droplet-to-particle pathway. Our study indicates that a droplet-to-particle-pathway could be present even when processing the acidic formulation. However, even if a secondary pathway might take place in this case as well, it is not dominant and nearly negligible. Subsequently, the in situ particle structure evolution was investigated for the dominant gas-to-particle pathway, and particles were extracted along the flame axis for online SMPS and offline TEM/HRTEM analysis. Due to the highly reactive conditions within the flame (high temperatures, turbulent flow field, high particle number concentrations), the extraction of representative samples from spray flames is challenging. In order to handle the reactive conditions, two extraction techniques were tailored in this report. To extract an aerosol sample within the flame for SMPS measurement, a Hole in a Tube probe was adjusted. Thus, the mobility particle diameter as well as the corresponding distribution widths were obtained at different heights above the burner along the flame axis. For TEM/HRTEM image analysis, particle samples were collected thermophoretically by means of a tailored shutter system. Since all sampling grids were protected until reaching the flame axis and due to the low sampling time, momentary captures of local particle structures could be extracted precisely. The particle morphologies have clearly shown an evolution from spherical and paired particles in the flame center to fractal and compact agglomerates at later synthesis stages.

Straightforward Immobilization of Phosphonic Acids and Phosphoric Acid Esters on Mesoporous Silica and Their Application in an Asymmetric Aldol Reaction

<jats:p>The combined benefits of moisture-stable phosphonic acids and mesoporous silica materials (SBA-15 and MCM-41) as large-surface-area solid supports offer new opportunities for several applications, such as catalysis or drug delivery. We present a comprehensive study of a straightforward synthesis method via direct immobilization of several phosphonic acids and phosphoric acid esters on various mesoporous silicas in a Dean–Stark apparatus with toluene as the solvent. Due to the utilization of azeotropic distillation, there was no need to dry phosphonic acids, phosphoric acid esters, solvents, or silicas prior to synthesis. In addition to modeling phosphonic acids, immobilization of the important biomolecule adenosine monophosphate (AMP) on the porous supports was also investigated. Due to the high surface area of the mesoporous silicas, a possible catalytic application based on immobilization of an organocatalyst for an asymmetric aldol reaction is discussed.</jats:p>

Hydrogels as Porogens for Nanoporous Inorganic Materials

C. Weinberger, D. Kuckling, M. Tiemann, Gels (2018), 83

<jats:p>Organic polymer-hydrogels are known to be capable of directing the nucleation and growth of inorganic materials, such as silica, metal oxides, apatite or metal chalcogenides. This approach can be exploited in the synthesis of materials that exhibit defined nanoporosity. When the organic polymer-based hydrogel is incorporated in the inorganic product, a composite is formed from which the organic component may be selectively removed, yielding nanopores in the inorganic product. Such porogenic impact resembles the concept of using soft or hard templates for porous materials. This micro-review provides a survey of select examples from the literature.</jats:p>
