“Hungarian Mine Green”, a Semi‐Natural Copper Pigment From Banská Bystrica Region (Slovakia) ‐ Analytical Evidence and Laboratory Replication

open access: yesChemPlusChem, Accepted Article.
A comprehensive approach was taken to investigate the “Hungarian mine green” pigment, including a historical overview, analysis of the pigment on artworks, and its laboratory replication. It is known that in the past the pigment was collected in wooden reservoirs in which copper (Cu) compounds precipitated from drainage water during copper mining at ...

Epitaxy and Topotaxy in the Aragonite‐Calcite Polymorphism

open access: yesCrystal Research and Technology, EarlyView.
At first distinguish epitaxy from topotaxy, which rule the main mechanisms of calcite‐aragonite transitions. Then, attempt to move from qualitative to quantitative descriptions of these transitions. Hence, it will deal with 2D (epitaxy) and 3D (topotaxy) conversions in the polymorphic system, in order to gain insight on their differences.

Synthetic Lignin Oligomers: Analytical Techniques, Challenges, and Opportunities

open access: yesChemSusChem, EarlyView.
The review begins by discussing lignin and its structural complexity, followed by challenges in elucidating depolymerization products and the analytical techniques used. It then focuses on the chemical structure of synthetic lignin oligomers, their synthesis mechanisms, and their significance in current science. Finally, scientific gaps are identified,
