Transition‐Metal Azo Schiff Base Complexes: Nonlinear Optics Across Solutions, Thin Films and Nanocomposites

open access: yesAdvanced Optical Materials, Volume 13, Issue 30, October 24, 2025.
The excitation of a transition‐metal azo Schiff‐base complex with a 1064 nm laser induces a series of nonlinear optical effects. These effects include the second harmonic generation at 532 nm and third harmonic generation at 355 nm. This process demonstrates the potential of the complex for high‐order nonlinear optical applications. Abstract This paper

Applying sterols and bile acids as biomarkers for identifying human versus wild animals' faecal traces in cave sediments at archaeological sites

open access: yesArchaeometry, Volume 67, Issue 4, Page 1022-1039, August 2025.
Abstract Faecal biomarkers are used to trace and identify the source of faecal matter at various types of archaeological sites. Until now, the focus has been centred on humans and domesticated animals. However, in caves, it's wild animals that play a role in the deposition of organic matter.

The first isotopic evidence of Early Iron Age lead ore exploitation in the Silesian‐Krakow upland, Poland: a provenance study of Lusatian culture lead ornaments

open access: yesArchaeometry, Volume 67, Issue 3, Page 552-569, June 2025.
Abstract The Bronze and Early Iron Ages witnessed a significant increase in trade relations driven by the search for valuable metals. This paper presents new insights into the use of galena from the Silesia and Krakow Upland region in southern Poland, known as the ‘Olkusz ore deposits’, within the context of metal ores in prehistoric Europe.

Phosphoric Acid Versus Biogenic Mineralization of Hydroxyapatite and Carbonate Apatite in Relation to Infection‐Induced Urinary Stones: Physical, Chemical and Microbiological Aspects

open access: yesChemPlusChem, Volume 90, Issue 5, May 2025.
Phosphoric acid is used in various products like food, sweets, beers, and soft drinks. Higher phosphoric acid concentration in urine accelerates the formation of carbonate apatite and hydroxyapatite, which are key components of infection urinary stones, a negative effect. However, the amount of these solid phases is smaller, which is beneficial.
