Abstract:
Aluminum alloys were reinforced with AlN particles using a novel chemical in situ technique. Thermodynamic analyses were made to identify the conditions for the in situ formation of the AlN in Al alloys. Experiments were conducted in the temperature range of 1173-1473 K by injecting ammonia gas. The composites with AlN quantity varying from 5 to 51 wt % were produced. Effect of process variables such as gas injection time, flow rate of ammonia gas and temperature of the alloy melt on the formation of AlN was studied. Increase in either injection time or flow rate of the ammonia gas increased t

AbstractUsing samples from a prehistoric quarry site in the Mojave Desert, we tested and compared the two principal methods of rock-varnish cation-ratio dating, analysis of rock-varnish scrapings (R. I. Dorn, 1983, Quaternary Research 20, 49-73 and 1989, Physical Geography 13, 559-596) and analysis of rock varnish in situ (C. D. Harrington and J. W. Whitney, 1987, Geology 15, 967-970). Because we found no consistent relationship between the varnish cation ratio (K + Ca)/Ti, and the relative age of the varnish, neither method could be used to "cation-ratio date" the underlying chert artifacts.

This work describes experimental results concerning the chemical composition of the alloy patina and inlays from the medieval copper alloy door of the cathedral of Troia (southern Italy), dating back to 1127 CE. The analyses were conducted in situ with no sampling or sample preparation required, using a portable energy-dispersive X-ray fluorescence (ED-XRF) instrument. The compositional results show that the two door leaves were made using a binary alloy of copper and lead, while the nails, lion protomes, and handles have a different chemical composition.

In situ (intra-oral) caries models are used for two purposes. First, they provide information about oral physiological processes. Such information helps to detail our knowledge of the oral ecosystem and to verify conclusions from in vitro experiments. Second, in situ models are utilized to test preventive agents in the phase between laboratory testing and clinical trials. Most investigations involving enamel inserts have been aimed at testing new dentifrices. The experimental designs of such studies usually do not allow one to draw conclusions on physico-chemical processes, e.g., because of si

To improve this situation, the development of new techniques allowing for structure observation during sample preparation is necessary. This is a critical step towards mitigating the influence of stochastic factors, thereby increasing the reliability and predictability of the outcomes. For real-time structural analysis

Abstract:
The focus in the present study was to establish whether there is a reasonable correlation between the Charpy Vee Notch (CVN) toughness and the non-destructive Potential Difference (PD) measurements of ferritic-pearlitic steels having a range of CVN toughness values. Complete material characterization was carried out for six steels procured for this program. The characterization included chemical analysis, microstructural information, tensile properties and CVN transition curves. In addition, most of the data including the CVN transition curves were available for five suitable pipe line steels

Abstract:
The purpose of this project was to establish a practical metallographic protocol to distinguish between high pH SCC and near-neutral pH SCC in the ditch. The protocol addresses how to distinguish the crack propagation modes. In addition, the protocol addresses procedures for preparation of sample location areas for analysis through the use of mechanical, electrical, and chemical means considering the quality of results, ease of use, portability, and reliability.

Abstract:
Within the BMBF funded second phase of the DAM project „Ausschluss mobiler grund-berührender Fischerei (MGF) in marinen Schutzgebieten der Ostsee – Phase II (MGF-Ostsee-II)“ an experimental field study has been conducted to determine the effects of bottom trawling on the benthic ecosystem of the German coastal Baltic Sea. An area characterized with low fishing activity was selected in the Mecklenburger Bight ca. 5 km north of the town Kühlungsborn based on geo-acoustic and sedimentological criteria. In a part of this area referred to as High Impact area, high intensity trawling was simulated b

ALKOR cruise AL583 took place as part of the EMFF (European Maritime and Fisheries Fund)‐funded projects BASTA (Boost Applied munition detection through Smart data detection in and AI workflows; https://www.basta‐munition.eu) and ExPloTect (Ex‐situ, near‐real‐time detection compound detection in seawater) (also EMFF‐funded). It was the continuation of the munition monitoring started within the BMBF‐funded project UDEMM (Environmental Monitoring for the Delaboration of Munition in the Sea; https://udemm.geomar.de/) and is already part of the new project CONMAR (https://conmar‐ munition.eu/) as
