Visualising the Invisible: Active Sites in Antibacterial Nanomaterials

Fluorescence lifetime microscopy has great potential to systematically enhance the effectivenes of antibacterial nanomaterials

20-Dec-2024 - Interest in antibacterial nanomaterials has surged due to the growing threat of antibiotic-resistant microbes. A particularly promising strategy involves the use of nanomaterials that generate reactive oxygen species upon exposure to light, effectively combating microorganisms. However, a key ...

New general manager at Oxford Instruments WITec in Ulm

18-Dec-2024 - The next era has begun at Oxford Instruments WITec, where Dr. Benjamin Tordoff is leading the Raman imaging microscopy pioneers after taking over from the company's founders. Dr. Benjamin Tordoff joined Oxford Instruments WITec this summer, though the company and its exceptional technology that ...

A stronghold in the fight against viruses - new bacterial immune system decoded

International research team describes for the first time the structure and function of the Zorya system

16-Dec-2024 - Bacteria are constantly infected by viruses, so-called phages, which use the bacteria as host cells. However, in the course of evolution, bacteria have developed various strategies to protect themselves from these attacks. Many of these bacterial immunity systems have been known for a long time. ...

10,000 times faster than traditional methods

New computational framework discovers experimental designs in microscopy

12-Dec-2024 - For human researchers, it takes many years of work to discover new super-resolution microscopy techniques. The number of possible optical configurations of a microscope — for example, where to place mirrors or lenses — is enormous. Researchers at the Max Planck Institute for the Science of Light ...

Unique X-ray microscope paves the way to more powerful batteries

New insights into the morphological and chemical changes in battery materials

21-Nov-2024 - New cathode materials are being developed to further increase the capacity of lithium batteries. Multilayer lithium-rich transition metal oxides (LRTMOs) offer particularly high energy density. However, their capacity decreases with each charging cycle due to structural and chemical changes. ...

Next step in light microscopy image improvement

New deep learning architecture enables higher efficiency compared to widely used methods

21-Nov-2024 - It is the computational processing of images that reveals the finest details of a sample placed under all kinds of different light microscopes. Even though this processing has come a long way, there is still room for increasing for example image contrast and resolution. Based on a unique deep ...

Surprise at the grain boundary

For the first time, an international research team has been able to observe how solute elements introduce new grain boundary phases using state-of-the-art microscopy and simulation techniques

31-Oct-2024 - Using state-of-the-art microscopy and simulation techniques, an international research team systematically observed how iron atoms alter the structure of grain boundaries in titanium. They were in for a surprise: “Iron atoms not only segregate to the interface, but they form entirely unexpected ...

Ovulation filmed from start to finish for the first time

New findings for fertility research

25-Oct-2024 - Approximately 400 times in a woman's life, a mature egg makes the “leap.” It is released into the fallopian tube, ready for fertilization by the sperm. Researchers led by Melina Schuh, Christopher Thomas, and Tabea Lilian Marx from the Max Planck Institute (MPI) for Multidisciplinary Sciences ...

Researchers can measure distances in molecules optically

MINFLUX microscopy allows the determination of distances within biomolecules using an optical microscope

15-Oct-2024 - A team led by physicists Steffen Sahl and Stefan Hell at the Max Planck Institute for Multidisciplinary Sciences in Göttingen and the Max Planck Institute for Medical Research in Heidelberg has succeeded in measuring distances within biomolecules using a light microscope, down to one nanometer ...

Cost-effective modular system for optical imaging from the 3D printer

Like building with Lego bricks

14-Oct-2024 - Making modern microscopy and spectroscopy methods accessible to as many users as possible - Prof. Thorben Cordes and his doctoral student Gabriel G. Moya Muñoz have dedicated themselves to this goal. Cordes joined the Faculty of Chemistry and Chemical Biology (CCB) at TU Dortmund University as ...
