The autoxidation of polyether-polyurethane open cell soft foam: An analytical aging method to reproducibly determine VOC emissions caused by thermo-oxidative degradation (2024)
Sandten, Christian ; Kreyenschmidt, Martin ; Albach, Rolf
We present a new method for investigating the oxidation and emission behavior of air-permeable materials. Employing this method, a differentiated statement can be made about the extent to which critical volatile organic compounds (VOCs) such as formaldehyde, acetaldehyde, and acrolein are contained in the material as impurities or formed by thermo-oxidative degradation of the polymer matrix in the use phase. The parameters affecting methods of VOC analysis are reviewed and considered for the developed method. The molecular mechanisms of VOC formation are discussed. Toxicological implications of the reaction kinetics are put into context with international guidelines and threshold levels. This new method enables manufacturers of cellular materials not only to determine the oxidative stability of their products but also to optimize them specifically for higher durability. Environmental Implication: Cellular materials are ubiquitous in the technosphere. They play a crucial role in various microenvironments such as automotive interiors, building insulation, and cushioning. These materials are susceptible to oxidative breakdown, leading to the release of formaldehyde, acetaldehyde, and acrolein. The ecotoxicological profiles of these compounds necessitate monitoring and regulation. The absence of reproducible and reliable analytical methods restricts research and development aimed at risk assessment and mitigation. This work significantly enhances the toolbox for optimizing the oxidative stability of any open-cell cellular material and evaluating these materials in terms of their temperature-dependent oxidation and emission behavior.
The Thermo-Oxidative Degradation of Polyurethane Open-Cell Soft Foam Investigated Through Gas Chromatography and Mass Spectrometry of Volatile Organic Compounds (2024)
Sandten, Christian ; Kreyenschmidt, Martin ; Albach, Rolf ; Fittschen, Ursula
Polyurethane (PUR) soft foams release malodorous and potentially toxic compounds when exposed to oxidative conditions. Current chamber test methods cannot distinguish between pre-existing volatiles and those formed during oxidation, nor can they assess the formation rates of oxidation products. We subjected PUR soft foam to oxidative treatment in a continuous air flow at 120 ◦C. Emissions were convectively transferred from the foam to an exhaust port and analyzed using a thermodesorption–gas chromatography–mass spectrometry (TD-GC-MS) system, with external calibration employed for the quantification of selected analytes. The study identified hydroperoxide formation and degradation as key mechanisms in the breakdown of the polyether soft segments. This process predominantly produces volatiles, such as carboxylic acids, formates, acetates, alpha-hydroxy-ketones, (unsaturated) aldehydes, substituted dioxolanes and dioxanes, glycols, and allyl ethers. Volatiles associated with the degradation of the hard segments include aniline, benzoxazole, 2-methylbenzoxazole, and benzaldehyde. This experimental setup enables reproducible qualitative and quantitative analysis of volatiles formed during the oxidative degradation of PUR soft foams, providing new insights into the segment-dependent chemical pathways of the polymer’s molecular breakdown.
VOC EMISSIONS FROM PARTICLE FILTERING HALF MASKS – METHODS, RISKS AND NEED FOR FURTHER ACTION (2021)
Kerkeling, Saskia ; Sandten, Christian ; Schupp, Thomas ; Kreyenschmidt, Martin
Investigations into volatile organic compound (VOC) emissions from polymer fleeces used in particle filtering half masks were conducted and evaluated against the German hygienic guide value for total volatile organic com- pounds and the “Lowest Concentration of Interest” for construction products. All masks showed emission of Xy- lene. In 94 % of samples, up to 24 additional aromatic compounds were found. 17 % of samples showed terpenes, 53 % emitted aldehydes, 77 % exhibited caprolactam and 98 % released siloxanes. All masks exceeded the TVOC hygienic guidance value level 5 of 10 mg/m³. Emission levels were investigated for masks immediately after their packages were opened and for masks that were “vented” for two weeks. Further, the emissions were repeatedly measured to investigate the decrease of emissions. An exponential decline was observed and a fitting function was calculated. The influence of the two commonly gas chromatograph (GC) hyphenated detectors, mass spectrometer (MS) and flame ionization detector (FID) on the VOC quantification, as well as the influence of temperature on the emission of VOCs were investigated. A statistical analysis of emission value differences for Notified Bodies was conducted and CE 2163 and 2020-1XG proved to be outliers.

Revisiting the nutritional advantages of plant-based food matrices: a systematic review on the influence of spontaneous fermentation (2025)
Atuna, Richard A. ; Akabanda, Fortune ; Andrade Laborde, Juan E. ; Makurat, Jan ; Bordewick-Dell, Ursula ; Lamping, Matthias ; Ritter, Guido
This systematic review critically examines existing literature on the effects of spontaneous fermentation on the nutritional and antinutritional properties of the aforementioned food staples, focusing on the changes in nutrients, digestibility, and antinutrients. The literature search flow was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRiSMA-2020) approach. Only peer-reviewed journal articles published in English between 2002 and 2024 were sourced from Scopus, Web of Science, and PubMed. A total of 67 articles were considered eligible after the title, abstract, full text, and quality assessment. It was evident from the various studies consulted in this review that traditional fermentation, though being an ancient food processing practice, remains an important approach for increasing the level of nutrients, reducing antinutritional factors, and enhancing the nutrient digestibility of cereals, legumes, roots, tuber, and plantain. This has made fermented foods an important part of diet and nutrition in many cultures around the world, especially in the global south, with limited access to sophisticated food processing techniques and infrastructure. Overall, the findings suggest that incorporating spontaneous fermentation into the preparation of cereals, legumes, roots, and tuber crops can be a valuable strategy for enhancing the nutritional value and health-promoting properties of these dietary staples.

Einsatz von Big Data und Künstlicher Intelligenz zur Stärkung der Supply-Chain-Resillienz (2025)
Buchholz, Wolfgang
Das Konzept der Supply-Chain-Resilienz (SCR) hat seit der Covid-19-Pandemie erheblich an Bedeutung gewonnen, da Unternehmen verstärkt mit unvorhersehbaren Störungen in ihren Lieferketten konfrontiert sind. Trotz des zunehmenden Interesses an SCR bleibt das Potenzial digitaler Technologien, insbesondere im Bereich der Big Data Analysis (BDA) und Artificial Intelligence (AI), für die Stärkung der Resilienz noch weitgehend unerforscht. Diese Studie analysiert daher den Einfluss von BDA und AI auf präventive und reaktive Maßnahmen zur Förderung der SCR. Ein konzeptionelles Modell wird entwickelt, um präventive und reaktive Maßnahmen zu kategorisieren, bevor die Nutzung von BDA und SCR näher untersucht wird. Die Ergebnisse deuten darauf hin, dass digitale Technologien grundsätzlich die SCR unterstützen können; BDA und AI werden als vielversprechende Technologien identifiziert. Es wird jedoch festgestellt, dass der Einfluss dieser Technologien je nach proaktivem oder reaktivem Ansatz etwas variiert. Während digitale Technologien im proaktiven Ansatz einheitlich als unterstützend wahrgenommen werden, sind die Einschätzungen zum reaktiven Ansatz vielfältiger.

Simulating the overload of medical processes due to system failures during a cyberattack (2025)
Willing, Markus ; Ebbers, Simon ; Dresen, Christian ; Czolbe, Marc ; Saatjohann, Christoph ; Schinzel, Sebastian
Today’s medical IT is more and more connected and network or IT system outages may impact the quality of patient treatment. IT outages from cyberattacks are particularly worrisome if attackers focus on those medical IT devices that are critical for medical processes. However, medical processes are primarily documented for the hospital employees and not for analyzing the criticality of any given human or medical IT resource. This paper presents a generic model for realistic, patient-focused simulation of medical processes. The model allows the simulation of cyber incidents, focusing on device outages or overload situations like mass casualty incidents. Furthermore, we present a proof-of-concept tool that implements the described model, enabling end-users to simulate their processes. The tool offers the ability to run with low detailed data for overview purposes and highly detailed data for fine-grained simulation results. We perform different scenario simulations for a sample hospital, including the acute phase of a ransomware attack, negative performance impacts due to the implementation of cybersecurity measures, and emergency plans for mass casualty incidents. In each scenario, the respective simulation resulted in a quantitative statement of how these scenarios affect overall process performance and show possible key factors supporting decision-making. We use real-world data from a German trauma room to optimize and evaluate the process simulation.
