(Press-News.org) It is a result of his ERC Consolidator Grant-funded project POPCRYSTAL, with which Paolo Falcaro from the Institute of Physical and Theoretical Chemistry at TU Graz has now acquired an ERC Proof of Concept Grant (PoC). The new project called FRESCO, which is being funded to the tune of 150,000 euros over a period of 18 months, aims to increase food safety and reduce food waste. This is made possible by a microporous crystalline composite developed as part of the POPCRYSTAL project, which detects toxic chemical compounds that are produced when protein-rich foods such as fish, meat or cheese spoil.
Composite ink recognises toxic compounds
A class of microporous crystals, also known as metal-organic frameworks (MOFs), are considered to have great potential in the field of materials science, as they have a very large surface area despite their small size. Depending on the arrangement of their pores, they can have a wide variety of properties. Paolo Falcaro succeeded in controlling the pore orientation in the POPCRYSTAL project. Building on this work, and through collaborations established within the framework of the TU Graz Lead Project 'Porous Materials at Work for Sustainability,' lithographic methods for the development of MOF-based applications were explored, resulting in preliminary findings published in Advanced Materials. These promising results will now be researched in FRESCO to further develop a sensitive ink that helps to detect food spoilage.
The basis for this is a MOF developed during POPCRYSTAL that can be applied to the inside of food packaging in the form of a non-toxic composite ink. The composite ink changes colour depending on the concentration of toxic compounds in the packaged food. This makes it possible to determine whether the food is still edible or not. During the new ERC project, Paolo Falcaro and his team, together with other researchers from TU Graz, want to improve the composition of the MOF ink, test its effectiveness and find suitable partners from the packaging industry to bring the development into application. This is also the intention behind the Proof of Concept Grant: to build on an ERC grant that has already been acquired and to evaluate the research results for marketable innovation potential.
Paolo Falcaro says: “Improving food safety and reducing food waste are global challenges. FRESCO is therefore also in line with the United Nations Sustainable Development Goals (SDGs), which aim, among other things, to increase food safety and achieve a more sustainable use of food through a more responsible consumption of products. If packaging can continuously monitor the freshness of food with our MOF, this should prevent the premature disposal of food that is still edible as well as the consumption of spoilt food.”
Materials science as a field of scientific strength at TU Graz
As a proven field of scientific strength at TU Graz, research in the field of materials science is both intensive and successful. Several ERC grants have already been acquired here and a total of seven Christian Doppler Laboratories are dedicated to topics such as nanoprobes, geopolymer construction materials from mineral waste or mass transport through paper. In addition, a Lead Project is underway that deals with porous materials.
“TU Graz congratulates Paolo Falcaro and his team on this ERC Proof of Concept Grant,” says Andrea Höglinger, TU Graz Vice Rector for Research. “Our researchers in the field of materials science, particularly in the area of porous materials, are constantly achieving results that attract international attention. The ERC grant for the FRESCO project is further proof of this outstanding research work.”

Offline versus online promotional media: Which drives better consumer engagement and behavioral responses?
2025-01-23
Marketers today increasingly rely on online platforms like mobile apps, social media, and direct email to deliver promotional content, drawn by their cost-effectiveness and extensive reach. However, despite these advantages, traditional offline promotion, such as printed coupons, might still outperform their digital counterparts in driving consumer behavior.
Offline media are reported to enhance consumers’ ability to recall promotional content and improve their perception of the advertised products. Yet, a direct comparison of how offline and online promotional media affect consumer behavior has remained largely unexplored.

Empowering numerical weather predictions with drones as meteorological tools
2025-01-23
Climate change is making extreme weather events worse, empowering meteorological phenomena such as storms, hurricanes, heatwaves, and droughts. Against this backdrop, numerical weather predictions (NWPs), which use complex mathematical models that simulate atmospheric conditions, have become critical to protect people and businesses from these events and other weather-borne disasters.
Unsurprisingly, NWP models need a massive amount of daily data to make accurate predictions. While some of this data comes from satellite images and ground-based stations, a fine atmospheric vertical structure ...
From root to shoot: How silicon powers plant resilience
2025-01-23
Silicon (Si) is one of the most abundant elements on Earth, found in large quantities in soil. While Si is not essential for land plants, many plants, such as rice and grasses, have used Si to develop powerful defense mechanisms against various environmental stresses. Si accumulates in plant leaves and aerial organs as amorphous silica (SiO2), which offers protection against pathogens, herbivores, and environmental challenges like drought. Understanding the processes through which plants manage this beneficial element could enhance crop resilience and productivity, especially in the face of climate change.

Curiosity- driven experiment helps unravel antibiotic-resistance mystery
2025-01-23
An international collaboration has achieved an important breakthrough in understanding the genetic mechanisms that allow bacteria to build resistance to drugs.
Bacteria have multiple defence mechanisms they can use to build resistance to antibiotics, one of the major problems facing public health globally.
One of these mechanisms involves plasmids, small DNA molecules in bacterial cells, which have their own independent genome and carry antibiotic resistance.
If we can work out the roles plasmids play inside bacteria, then we can use the information to develop a new generation of therapeutics that can target drug resistant infections.

Adults diagnosed with ADHD may have reduced life expectancies
2025-01-23
Adults who have been diagnosed with attention deficit hyperactivity disorder (ADHD) may be living shorter lives than they should, finds a world-first study led by UCL researchers.
The research, published in The British Journal of Psychiatry, analysed anonymised primary care data from 30,029 adults across the UK with diagnosed ADHD.
They then compared this group with 300,390 participants without ADHD, who were matched by age, sex, and primary care practice.
The researchers found an apparent reduction in life expectancy for men with diagnosed ADHD of between 4.5 and 9 years, and between 6.5 and 11 years for women.
