Dual Isotope Analysis Reveals Phylogenetic Patterns and Novel Insights Into Methoxy Group Synthesis of Structural Biomolecules in Leaf and Woody Plant Tissues

Plant, Cell &Environment, Volume 48, Issue 12, Page 8483-8501, December 2025.
ABSTRACT Stable carbon and hydrogen isotopes of wood methoxy groups (δ2Hmeth, δ13Cmeth), mainly sourced by structural biomolecules like lignin and pectin, provide important insights into climatic, hydrological and physiological conditions. This study systematically investigated species‐specific δ2Hmeth and δ13Cmeth variations in leaves and woody twigs ...

A Modular Microfluidic System to Generate Gradient Hydrogels with Simple‐to‐Complex Stiffness Profiles for Mechanobiology

Advanced Materials Technologies, Volume 10, Issue 22, November 19, 2025.
This work introduces a universal approach for fabricating stiffness gradient hydrogels with diverse stiffness ranges and gradient profiles. Gradient formation is achieved by precisely controlling the thermal landscape within a microfluidic system, which drives thermophoretic redistribution of precursor components in solution.

Substrate Effect on the Contribution of Ammonium and Urea to Marine Nitrification and Nitrous Oxide Production

Environmental Microbiology, Volume 27, Issue 10, October 2025.
The urea to ammonium concentration ratio is a good predictor of the relative importance of urea and ammonium to nitrite and N2O production in the ocean. In addition, the urea to ammonium ratio may be a key factor in shaping the genetic capability of marine ammonia‐oxidising archaea for urea utilisation.

NEW RESTORED DENARIUS OF TRAJAN FROM CARCABOSO, CÁCERES (CONVENTUS EMERITENSIS, LUSITANIA)

Journal of Ancient History and Archaeology, 2019
A recent and new Republican denarius restored by Trajan is studied and discussed. The issue is extremely rare as no image of it is known so far. It was found in Carcaboso, Cáceres (Conventus Emeritensis, Lusitania), very near of the road known as Vía de ...

Understanding the Dissolution Kinetics of a DINCH Plasticized PVC: Experimental Design and Applied Modeling

ChemSusChem, Volume 18, Issue 17, September 1, 2025.
Experimental design and applied modeling of the dissolution kinetics of poly(vinyl chloride) containing di‐isononyl‐1,2‐cyclohexaandicarboxylaat (DINCH) plasticizer, with varying temperature (T), plastic particle size (dp), and solvents. Polymer dissolution‐precipitation recycling is a promising pathway to increase plastic recycling rates.

The Roman Water Management of Arles as Read in Aqueduct Carbonate Archives

Geoarchaeology, Volume 40, Issue 4, July/August 2025.
ABSTRACT This article reconstructs the complex history of modifications made to the Roman aqueduct of Arelate (Arles), by studying carbonate incrustations in its channels. These deposits, precipitated by flowing water, have preserved an archive of the aqueduct's life‐cycle in their stratigraphy, fabric and stable isotope composition.

Fetal growth restriction adversely impacts trajectory of hippocampal neurodevelopment and function

Brain Pathology, Volume 35, Issue 4, July 2025.
Hippocampal neuron dendritogenesis occurs rapidly in late fetal gestation and forms the foundation for connectivity and long term function. Fetal growth restriction caused by placental insufficiency is associated with reduced dendritogenesis in hippocampal neurons, resulting in a significant decrease in the trajectory of neuro‐development.
