Can rainbows monitor the environment?
Can rainbows monitor the environment?
New nanotechnology may make it easier to identify the chemical composition of impurities and their geometrical shape in samples of air, liquid and live tissue. Using conventional testing techniques, it can be challenging - sometimes impossible - to detect harmful contaminants such as nano-plastics, air pollutants and microbes in living organisms and natural materials.

RNA-drug interac­ti­ons
RNA-drug interac­ti­ons
How active compounds affect RNA and thus the expression of genes is of great interest for the development of potential therapeutics. Innsbruck chemists have now used a method they recently developed to study the binding of the aminoglycoside Neomycin B to a so-called mRNA riboswitch. In important cellular processes, ribonucleic acids (RNA) specifically recognize certain proteins or small organic molecules as binding partners.

New catalysts for solar hydrogen production
New catalysts for solar hydrogen production
Researchers at TU Wien are developing a layered photocatalyst that can be used to produce hydrogen very efficiently from water. Finding sustainable and clean fuels is crucial in today's global energy and climate crisis. One promising candidate that is increasingly gaining relevance is hydrogen. However, today's industrial hydrogen production still has a considerable CO2 footprint, especially considering processes like steam reforming or non-sustainable electrolysis.

Current thinking on batteries overturned by cathode oxidation research
Current thinking on batteries overturned by cathode oxidation research
Nickel-rich cathode materials are used in lithium-ion batteries, but their practical applications have been limited. Scientists have made a significant breakthrough in understanding and overcoming the challenges associated with Ni-rich cathode materials used in lithium-ion batteries. These materials have the potential to achieve both high voltages and capacities, but their practical applications have been hindered by structural instabilities and loss of oxygen.

High-performance digital system for the design of customized polymers
It is impossible to imagine everyday life without polymers. However, they represent only a small section of the huge number of polymers that could theoretically exist. Christopher Kuenneth at the University of Bayreuth, Germany, together with research partners in Atlanta, USA, has now developed a digital system that promises extraordinarily high economic, technological and ecological benefits: From around 100 million theoretically possible polymers, it can filter out at unprecedented speed precisely those materials that are most suitable for targeted applications.

Why our body runs like clockwork
Why our body runs like clockwork
The friction in our joints is extremely low - how is that physically possible at all? Measurements at TU Wien provide explanations and ideas for new treatment methods . Friction and wear as an eternal nuisance - this is as familiar in technology as it is in medicine. Whether it's a manual transmission or a knee joint, you always want moving parts to slide over each other with as little friction as possible, so that energy expenditure and wear are kept to a minimum.

The plant origins of active ingredients
The plant origins of active ingredients
Since the dawn of time, humans have used plants to heal themselves. But it wasn't until the 18th century that we began to understand that this healing power came from certain specific compounds: active ingredients. In a collective work for the general public entitled 'Plantes soignantes' (Healing plants), the contributions of two biology researchers from the University of Neuchâtel, Emmanuel Defossez and Sergio Rasmann, retrace the major stages in this quest, the potential of which remains largely unexplored .

Secrets of Egyptian painters revealed by chemistry
Secrets of Egyptian painters revealed by chemistry
Contrary to prior assumptions, ancient Egyptian painters did at times push the boundaries of convention. Artistic creations supposed to be copies of canonical images were in fact often adapted and reworked during their execution. This discovery was made using new, portable chemical imaging tools that leave the artworks intact.
