Isabell Grothaus about the CD Spectrometer:
"We exploit the method to monitor structural changes in proteins upon changes in their environment, introduction of mutations or alterations in post-translational modifications."
© Patrick Pollmeier, Universität Bremen
Marcos Toro about the AFM:
"Atomic force microscopy lets us visualize surfaces at the atomic level, providing detailed topographical maps that reveal nanoscale features essential for cutting-edge research."

Wolf-Achim Kahl about the Xradia 520 Versa:
"3D insights into mineral textures help me to understand how reactive processes in the ocean crust influence the geochemistry of the rocks and ocean, and even the development of microbial habitats."
© Patrick Pollmeier, Universität Bremen
Florian Krause about the Titan Spectra 300:
"We can uncover the precise structure of materials down to the range of picometers. This allows us to reveal details like electric fields inside nanostructures on the sub-atomic scale."
© Patrick Pollmeier, Universität Bremen
Ella Schmidt about the D8 Advance X-ray Diffractometer:
"We unravel past climate histories, investigate the absorption properties of porous materials, and explore the structural complexities of nanoparticles."
© Patrick Pollmeier, Universität Bremen
Jon-Olaf Krisponeit about the Low-energy Electron Microscope:
"I can visualize surfaces in real-time while growing structures or films on them. This allows me to study surface phenomena and thin films with great clarity."
© Patrick Pollmeier, Universität Bremen
Jens Falta about the coupled STM, XPS, and LEED System:
"We can probe the elemental composition, chemical states, and structure of surfaces. This offers insights critical for the development of advanced materials and coatings."
© Patrick Pollmeier, Universität Bremen
Mangir Murshed about the LabRam ARAMIS:
“Using the microfocus Raman spectroscopy, I analyze the fingerprints of molecules and crystals, revealing their chemical composition and structural details.”
© Patrick Pollmeier, Universität Bremen
Marcos Toro about the coupled Raman-VSI Spectrometer:
"Coupling two optical methods for the analysis of surfaces allows us to study the molecular composition and the topological features of a surface in one instrument."

We use X-rays to non-destructively inspect the three-dimensional distribution of matter inside the object of investigation.

澳门皇冠_皇冠足球比分-劲爆体育

We investigate our samples using high-energy electron beams to obtain images with resolution down to the atom scale.

澳门皇冠_皇冠足球比分-劲爆体育

We combine microscopic and spectroscopic techniques to monitor processes at materials surfaces.

澳门皇冠_皇冠足球比分-劲爆体育

vertical Scanning Imaging and superimposed Raman Shift

We perform in-situ and real-time chemical, electronic and optical characterization of materials under different conditions, e.g. to identify and map different phases.

澳门皇冠_皇冠足球比分-劲爆体育

We support structure investigations of materials from crystalline nanomaterials to macroscopic single crystals at ambient and non-ambient conditions.

澳门皇冠_皇冠足球比分-劲爆体育

We develop and apply computational methods from quantum mechanics to continuum theories to design and understand new materials and processes.
