Efficiency of Sequential Extraction Schemes in Partitioning Toxic Elements in Acid Sulfate Soils With a Thionic Horizon

open access: yesEuropean Journal of Soil Science, Volume 76, Issue 2, March–April 2025.
ABSTRACT The use of sequential extraction methods is a common practice for analysing the availability of potentially toxic elements in soils and sediments. However, the simultaneous presence of oxidisable and reducible minerals in acid sulfate soils with a thionic horizon raises questions about the accuracy of these methods.

Ownership, institutions, and the agency of M&A completion

open access: yesGlobal Strategy Journal, Volume 15, Issue 1, Page 153-183, February 2025.
Abstract Research Summary In this paper, we study how variations in debt and equity ownership and the institutions that govern interactions between different types of principals and agents affect the completion likelihood of acquisitions. Using a sample of 55,722 acquisitions, our study finds that risk‐averse debtholders reduce the completion ...

Template‐Free ZSM‐5 Synthesis Using Bio‐Sourced Waste Materials

open access: yesEuropean Journal of Inorganic Chemistry, Volume 27, Issue 34, December 2, 2024.
Hydrochars from lignocellulosic waste were added to ZSM‐5 OSDA‐free synthesis. These bio‐sourced materials mediated the ZSM‐5 crystals aggregation during their synthesis. Thus, morphology and acidity changed due to the presence of hydrochars. Brønsted and Lewis acid sites were specially increased.

Geography and ecology shape the phylogenetic composition of Amazonian tree communities

open access: yesJournal of Biogeography, Volume 51, Issue 7, Page 1163-1184, July 2024.
Abstract Aim Amazonia hosts more tree species from numerous evolutionary lineages, both young and ancient, than any other biogeographic region. Previous studies have shown that tree lineages colonized multiple edaphic environments and dispersed widely across Amazonia, leading to a hypothesis, which we test, that lineages should not be strongly ...

Comparison of forages’ digestion levels for different in vitro digestion techniques in horses

open access: yesVeterinary Medicine and Science, Volume 10, Issue 2, March 2024.
The in vitro total enzymatic + fermentative digestion technique for horse forages revealed higher values than the in vitro fermentative digestion techniques. In general, the higher the non‐structural carbohydrate and crude protein contents in the forage, the higher the results of the in vitro TDT compared to the other techniques.
