European Journal of Soil Science, Volume 77, Issue 3, May–June 2026.ABSTRACT The dynamics of soil organic matter (SOM) and humic acids (HA) in a permanent and seasonal wetland located in southeastern Brazil (hydromorphic soils and gramineous vegetation) were assessed through thermogravimetry, evolved gas analysis, and analytical pyrolysis. The n‐alkane series in all samples spanned from C13 to C35, regardless of season,

Untangling nutrient co‐regulation of ombrotrophic peatland development
Boreas, Volume 55, Issue 2, Page 384-404, April 2026.Multi‐method (FTIR, FT‐NIR and TGA) approaches characterizing the organic peat constituents at Holcroft Moss reveal a record of switches that reflect broadly hydroclimate variability governing the decomposition patterns. There are periods, however, where hydroclimate does not fully explain the variability observed and instead changes appear linked to ...

Preparation of High‐Pressure Laminate With Bio‐Based Fructose‐HMF‐Amine Impregnation Resin
Journal of Applied Polymer Science, Volume 143, Issue 11, March 15, 2026.This study demonstrates the use of a resin made from renewable carbohydrates, free from phenol and formaldehyde, for impregnating recycled kraft paper to produce high‐pressure laminates. The resulting bio‐based laminate samples match the mechanical performance of conventional phenol‐formaldehyde‐based samples, highlighting their potential to replace ...

Bioinorganic Chemistry and Applications, 2005 Batch and column experiments were performed to determine the Cu(II) binding capacity of silica-immobilized humin biomass. For column studies, 500 bed volumes of a 0.1 mM Cu(II) solution were passed through humin packed columns at the flow rates of 1, 1.5,
