Hodgkin’s lymphoma, a type of lymph node cancer, requires chemotherapy and radiation therapy that can be very stressful for patients. A research group in Vienna is working on a method to predict the course of the disease with the help of artificial intelligence algorithms. This would facilitate a ...
Different cell states determine progression of the disease
05-Jan-2023
The development of brain metastases is a frequent occurrence in melanoma that is associated with a poor prognosis for the affected patients. The effectiveness of existing therapies varies greatly. The reasons for this variability, however, remain largely unknown. An international research team ...
Researchers cultivate "missing link" microorganism
29-Dec-2022
How did the complex organisms on Earth arise? This is one of the big open questions in biology. A collaboration between the working groups of Christa Schleper at the University of Vienna and Martin Pilhofer at ETH Zurich has come a step closer to the answer. The researchers succeeded in ...
Scientists were able to observe and document the growth of hexagonal boron nitride for the first time
28-Oct-2022
Atomically thin 2D materials for applications in microelectronics or nanotechnology are grown by breaking down gas on a hot metal surface. Due to the high temperatures and rapid transformation of the gas, it is extremely difficult to observe this process. Researchers from TU Graz have now joined ...
Adaptive imaging technique for materials science and structural biology
03-Oct-2022
A new technique that combines electron microscopy and laser technology enables programmable, arbitrary shaping of electron beams. It can potentially be used for optimizing electron optics and for adaptive electron microscopy, maximizing sensitivity while minimizing beam-induced damage. This ...
Information is obtained that none of the methods alone could reveal
30-Sep-2022
One has to look very closely to exactly understand what processes take place on the surfaces of catalysts. Solid catalysts are often finely structured materials made of tiny crystals. There are various microscopies to monitor chemical processes on such surfaces – they use, for example, ...
Andrea Hochegger, an analytical chemist at TU Graz, investigates whether foodstuffs can be tainted with harmful substances from packaging or during production
27-Sep-2022
Andrea Hochegger’s current research focus is the question of contamination with mineral oil hydrocarbons. “We break up complex mixtures into MOSH and MOAH fractions,” Andrea explains. These are groups of chemical compounds found in mineral oil. MOSH stands for mineral oil saturated hydrocarbons ...
A fingertip-sized chip replaces bulky laboratory equipment: The possible applications are extremely diverse
01-Sep-2022
An infrared sensor has been developed at TU Wien (Vienna) that analyses the content of liquids within the fraction of a second. In analytical chemistry, it is often necessary to accurately monitor the concentration change of certain substances in liquids on a time scale of seconds. Especially in ...
Femtosecond journey through graphene
23-Aug-2022
When ions penetrate a material, highly complex processes take place - so fast that they could hardly be analyzed until now. But sophisticated measurements have now made it possible. How do different materials react to the impact of ions? This is a question that plays an important role in many ...
Atomistically accurate description of proteins at native concentrations can help to better understand the process of cell proliferation to tumour growth
15-Aug-2022
Researchers determine the structure and dynamics of proteins using NMR (Nuclear Magnetic Resonance) spectroscopy. Until now, however, much higher concentrations were necessary for in-vitro measurements of the biomolecules in solution than found in our body's cells. An NMR method enhanced by a ...
