Upon exceeding a critical laser intensity, hard X-ray radiation is generated as a side effect. Even if the emitted X-ray dose per laser pulse is low, for currently available high-repetition-rate laser systems the accumulated X-ray dose becomes significant and radiation safety must be considered.

However, there is little evidence of dust-derived P-containing minerals in soils. Here we studied P forms along a well-described climatic gradient on Hawaii, which is also a dust deposition gradient. Soil mineralogy and soil P forms from six sites along the climatic gradient were analyzed with bulk (X-ray diffraction and P K-edge X-ray absorption near edge structure) and microscale (X-ray fluorescence, P K-edge X-ray absorption near edge structure, and Raman) analysis methods. In the wettest soils, apatite grains ranging from 5 to 30 μm in size were co-located at the micro-scale with quartz, a known continental dust indicator suggesting recent atmospheric deposition. In addition to colocation with quartz, further evidence of dust-derived P included backward trajectory modeling indicating that dust particles could be brought to Hawaii from the major global dust-loading areas in central Asia and northern Africa. Although it is not certain whether the individual observed apatite grains were derived from long-distance transport of dust, or from local dust sources such as volcanic ash or windblown fertilizer, these observations offer direct evidence that P-containing minerals have reached surface layers of highly-weathered grassland soils through atmospheric deposition.

In order to make optimal use of hydrogen as an energy carrier, the infrastructure for hydrogen storage and transport in particular, must meet high technical safety standards. The indispensable basis for such safety assessments are the material properties, which must be evaluated under operating conditions that are as real as possible. The conventional method for the assessment of the material properties in gaseous hydrogen is conducted by testing materials in high-pressure hydrogen gas in a pressure vessel (autoclave). It is an established method that allows to perform common standardized tests such as tensile, fatigue and crack growth tests under varying hydrogen conditions. However, this method is complex and entails high costs due to extensive safety regulations. The hollow specimen technique is a more efficient test method, which can be used to assess the mechanical properties of materials under high-pressure hydrogen gas. The procedure is conducted by enclosing high-pressure gas into a hole along the axis of the tensile test specimen. Recently, this method has been successfully performed at pressures up to 1000 bar and over a wide range of temperatures. Due to the low hydrogen volume needed, this method requires minimal safety regulation; therefore, the costs are reduced when compared to the conventional autoclave technique. This method is now in a standardization process, which has been initiated by Japan as a new working package in ISO (TC 164/SC 1/WG 9). The following contribution presents preliminary results obtained testing common grades of metastable austenitic stainless steel. For this purpose, the mechanical properties and fracture surface of solid and tubular specimens were assessed and compared using slow strain rate tensile (SSRT) test as part of the preliminary work at the Fraunhofer IWM. In a similar way, pipeline steels evaluated under hydrogen atmospheres using the geometry adapted by BAM will be presented. Within the framework of the TransHyDE flagship project, more results with the goal of supporting the standardization of the hollow specimen technique are expected to be obtained.

Ein Vergleich mit experimentellen Untersuchungen zeigt, dass die Berechnungen von Modellen, die z.B. für Erdgas geeignete sind, für sehr leichte Gase größere Abweichungen ergeben können. Es sind daher Modifikationen für das Integralmodell von Schatzmann und das empirische Modell von Chen/Rodi entwickelt und mit experimentellen Untersuchungen verglichen worden. Bei einer verzögerten Zündung der Wasserstoff-Gaswolke sind bei experimentellen Untersuchungen relevante Explosionsüberdrücke gemessen worden, die bei einer Gefährdungsbeurteilung berücksichtigt werden sollten.

Especially in the field of pharmaceuticals, fluorinated organic molecules are becoming more and more popular and at present amount up to 25% of market share, with an upward trend. Highly fluorinated organic substances are also used in technical applications (e.g., coatings, fire-extinguishing agents, textiles). However, next to beneficial aspects of per- and polyfluorinated compounds (PFAS) these substances belong to the class of “emerging contaminants” in particular due to their high persistence and ubiquitous presence in the environment. Due to the large variety of fluorinated substances and increasing production volumes, it is most likely that numerous and up to date unknown fluorine-species are present in the (aquatic) environment. Sum parameter analytical methods to assess the degree of contamination of surface waters with organically bound fluorine are highly needed. Within this presentation the development of a high resolution-continuum source-graphite furnace molecular absorption spectrometry (HR-CS-GFMAS) method for PFAS analysis is presented. Fluorine detection is enabled upon the addition of a molecule forming agent – Ga turned out being the most sensitive one. Furthermore, the injection as well as temperature program was optimized, and appropriate solid phase extraction (SPE) phases were identified for PFAS extraction. Our developed HR-CS-GFMAS method turned out as a versatile tool in PFAS analysis in a broad variety of matrices – some recent applications will be highlighted as well.

In particular metals play important roles in all areas of our daily life - from building materials to high tech products. However, due to the increasing consumption of metals and corresponding waste production, an elevated release of metals from buildings and consumer goods into the environment takes place. Furthermore, metals in direct contact with the environment undergo corrosion processes which leads also to a release of metals into the (aquatic) environment. Besides this immediate metal release, the lifespan of products/buildings are substantially reduced – hence unnecessary economic costs arise. Thus, research in this regard is needed within the force field of metal/material  environment. However, to evaluate the environmental impact of materials as well as developing “safe” materials, new analytical methods are highly needed. One promising powerful tool in this regard is single cell-ICP-ToF-MS for multi-elemental analysis on a single cell/organism level. Within this presentation the concept, strength as well as challenge of single cell-ICP-MS are briefly introduced. Afterwards, two application examples are presented: (i) assessing the environmental impact of metals and (ii) the impact of the environment on metal-based materials and the derivation of potential environmental-friendly material protection strategies. These applications highlight the strength of new analytical approaches to explore the durability and safety of newly developed materials. Thus, analytical chemistry is one corner stone to transformation of modern society into circular economy (CEco). (i) Diatoms are located at the bottom of the food chain. Thus, toxicological relevant metals taken up by diatoms can possibly accumulate within the food web and cause harmful effects. Diatoms are a common test system in ecotoxicology. To investigate potential metal uptake and harmful effects on a single cell level, we developed an on-line single cell-ICP-ToF-MS approach for multi-elemental diatom analysis. Our approach is a new potential tool in ecotoxicological testing for metal-based materials. (ii) Next to classical corrosion processes, microorganisms are responsible for so called microbially influenced corrosion (MIC). MIC is a highly unpredictable process relying on the interaction pathways between cells and the metal surface. To shed light on MIC processes and derivate potential metal protection strategies, we applied single cell-ICP-ToF-MS for MIC research on a single bacteria/archaea level. It turned out that microorganism are taking up particular metals from alloys - thus, single bacteria-ICP-ToF-MS will enable the development of environmental friendly corrosion protection strategies.

Different milling parameters are known to affect the mechanisms and rates of product formation: milling frequency, milling time, filling degree of the milling jar, ball diameter and vessel size, degree of milling ball filling, and material of jars. The increasing interest in mechanochemistry is contrasted by a limited mechanistic understanding of mechanochemical reactivity and selectivity. Control over ball milling transformations is needed before the transformative potential of mechanochemical processing can be realized. Different analytical methods and their combinations have been developed for the time-resolved in situ monitoring of mechanochemical transformations, including powder X-ray diffraction, X-ray absorption spectroscopy, NMR, Raman spectroscopy, and thermography. Here we will discuss our recent results investigating the formation of polymorphic cocrystals thereby elucidating the influence of milling parameters (solvent, temperature, time) and reaction sequences on the formation mechanism and kinetics. For the mechanochemical chlorination reaction of hydantoin normalizing the kinetic profiles to the volume of the milling ball showed clearly that milling reaction kinetics are conserved. Here physical kinetics dominate reaction rates in a ball-milling transformation. Attempting to interpret such kinetics in purely chemical terms risk misinterpreting the results. Our results indicate that time-resolved in situ investigations of milling reactions offer a new approach to tune and optimize mechanochemical processes.

The manufacturing defects and high RS are inherent of AM techniques and affect structural integrity of the components. Using XCT the defects size and shape distribution as well as geometrical deviations can be characterized, allowing the further optimization of the manufacturing process. Diffraction-based RS analysis methods using neutron and synchrotron X-rays at large scale facilities offer the possibility to non-destructively spatially resolve both surface and bulk RS in complex components and track their changes following applied thermal or mechanical loads.

N2 - Current decontamination strategies of PFAS-burdened soils mainly consist of adsorption methods using adsorbents for fixation of PFAS in the ground. A second option is the utilization of a “pump and treat” process, cycling polluted soils through a washing plant leading to the concentration of the pollutants in the fine fraction. Only a subsequent, high-energy consuming pyrolysis process guarantees the total destruction of all fluorinated organic contaminants. These approaches are cost-intensive and not intended for the direct decomposition of all PFAS contaminants. Hence, there is a great demand for innovative developments and chemical treatment technologies, dealing with new strategies of tackling the PFAS problem. Thus, we investigated mechanochemical treatment of PFAS contaminated soils with various additives in a ball mill and analyzed the PFAS defluorination with gas chromatography mass spectrometry (GC-MS) and liquid chromatography tandem mass spectrometry (LC-MS/MS), respectively, as well as the fluoride mineralization by ion chromatography (IC) and fluorine K-edge X-ray absorption near-edge structure (XANES) spectroscopy.

Additionally, they are also an integral part of medical applications especially in ophthalmology and to some extent in dentistry. The availability of highly repetitive powerful laser sources and advanced laser beam control systems have favored these developments. However, the laser processing may be accompanied by the generation of unwanted X-rays. Small doses per laser pulse can accumulate to significant dose levels at high laser pulse repetition rates. Moreover, burst mode processing increases the X-ray dose rates compared to single pulse use and results in X-ray photon energies up to 40 keV for tungsten targets. For laser treatment of human teeth, clearly noticeable X-ray skin dose rates can be found. The paper summarizes the current state of the art in the field of undesired generation of X-ray radiation during ultrashort pulse laser processing in air.

What makes them attractive for other fields of application is their short time-to-result and high sensitivity. Microplate-based assays such as ELISA have been adopted early in environmental and food analysis. Yet, to make immunoassays even faster, more sensitive, robust, and, most desirable, portable, advanced materials, sometimes developed for other purposes, can be profitably used to achieve these goals. Materials can be novel labels, e.g., chemical or particle labels, such as fluorophores or nanoparticles. Carrier particles, such as magnetic or polymer beads, make it possible to adopt the assays to meso- or microfluidic set-ups and encoding them opens the path to multiplex analysis.

As a result of continuous and prolific use, mainly in aviation firefighting foams, thousands of industrial and military installations have been found to contain contaminated soil, groundwater and surface water. Furthermore, current decontamination strategies of PFAS-burdened soils mainly consist of adsorption methods using adsorbents for fixation of PFAS in the ground.

Dies steht im Gegensatz zu den immer komplexer werdenden Verbundwerkstoffen und Strukturen in der Mineralbaustoffindustrie. Die manuelle Sortierung birgt viele Risiken und Gefahren für das ausführende Personal und basiert lediglich auf offensichtlichen, visuell erkennbaren Unterschieden zur Trennung. Eine automatisierte, sensorgestützte Sortierung dieser Baustoffe könnte diese Praxis ergänzen oder ersetzen, um die Verarbeitungsgeschwindigkeit, die Recyclingquoten, die Sortierqualität und die gesundheitlichen Bedingungen zu verbessern. Ein gemeinsames Projekt von Partnern aus Industrie und Forschungseinrichtungen nähert sich dieser Aufgabe, indem es die Kombination von Laser-induzierter Breakdown-Spektroskopie (LIBS) und VIS/NIR-Spektroskopie untersucht und testet. Durch die gemeinsame Verarbeitung der Informationen soll die Sortierqualität verschiedener Materialien wie Beton, Hauptmauerwerksbaustoffe, organische Bestandteile usw. deutlich verbessert werden. Darüber hinaus könnten Verunreinigungen wie SO3-haltige Baustoffe (Gips, Porenbeton usw.) erkannt und getrennt werden. Wir stellen aktuelle Fortschritte und Ergebnisse der Entwicklung eines Prüfstands vor, der LIBS mit NIR-Spektroskopie und visueller Bildgebung kombiniert. In Zukunft wird dieser Laborprototyp als vollautomatischer Messaufbau dienen, um eine Echtzeitklassifizierung von Bau- und Abbruchabfällen auf einem Förderband zu ermöglichen.

For instance, the manufacturing defects and high RS are inherent of additively manufacturing techniques and affect structural integrity of the components. Using XCT the defects size and shape distribution as well as geometrical deviations can be characterized, allowing the further optimization of the manufacturing process. Diffraction-based RS analysis methods using neutron and synchrotron X-rays at large scale facilities offer the possibility to non-destructively spatially resolve both surface and bulk RS in complex components and track their changes following applied thermal or mechanical loads.

The circularity is still low so that enhanced use of secondary building material is required to close loops. Three different secondary building materials are discussed based on exemplary research results: construction and demolition waste (C&D waste), soil-like material and incineration bottom ash (IBA). Focus was laid on the environmental compatibility of the materials examined mainly by standardized leaching tests. C&D waste was investigated after a wet treatment using a jigging machine, soil-like material and IBA were characterized with respect to their material composition. The environmental compatibility in particular was studied using standard leaching tests (batch tests and column tests). It was concluded that soil-like material can mostly be utilized even when the precautionary limit values set are exceeded by a factor of less than 2. For C&D waste the fine fraction below 2 mm and the content of brick material is problematic. IBA fulfills quality level HMVA-2 following German regulation. Higher quality levels of utilization might be achievable with better treatment technologies.

The possible areas of application for thermography in this context are just as diverse. Thermography is used in laser applications when permanent monitoring and control of thermal development is necessary. Among others, this is the case in additive manufacturing, laser-based measuring devices and non-destructive testing. Furthermore, thermography is ideally suited as a testing method when it comes to ensuring the quality of the laser itself. In this talk it is outlined, how lasers can be used as a heat source in active thermographic testing. Furthermore, two special variants (spatial & temporal structured heating) are described, for which lasers are highly suitable.

Neben klassischen Holz- und Pflanzenkohlen werden verstärkt so genannte Biokohlen produziert. Dieser Begriff findet Verwendung für mit Hilfe verschiedener Verfahren karbonisierte pflanzliche, tierische oder mikrobielle Ausgangsstoffe. Diese Kohlen werden zum Teil über weite Strecken zum Bestimmungsort transportiert (Überseetransporte) oder vor Verwendung für längere Zeit gelagert. Häufig zeigen diese Kohlen ein kritisches Selbstentzündungsverhalten, wobei Einstufungstests (UN N.4 Test) versagen können. Ein negatives Testergebnis des UN N.4 Tests führte dabei in der Vergangenheit zur Nichteinstufung als selbsterhitzungsfähiger Stoff; in der Praxis entzündeten sich aber bereits vergleichsweise kleine Schüttungen (einige m³), z. B. beim Seetransport in Containern. Ergebnisse eines Projektes zur systematischen Untersuchung verschiedener Pflanzenkohlen werden vorgestellt.
