Small Science, Volume 5, Issue 10, October 2025.Cell‐guided self‐assembly of thiophene based molecules inside living cells produces photostable, biocompatible nanofibers exhibiting J‐like excitonic coupling and stimulated emission. Integrated spectroscopic and quantum‐chemical analyses reveal unique photophysical behavior and low phototoxicity, positioning these supramolecular structures as ...

Physical properties of MTA, BioAggregate and Biodentine in simulated conditions: A micro-CT analysis
Dental Materials Journal, 2020 The aim of this study was to evaluate the physical properties of calcium-silicate based cements as retrograde filling in different pH and blood conditions using micro-CT. Eighty-four teeth were obturated and after root-end resection, 3 mm-deep root-end cavity was ultrasonically prepared. The samples were divided into four test groups (n=21).

Quantitative assessment of microbial necromass contribution to soil organic matter
Global Change Biology, Volume 25, Issue 11, Page 3578-3590, November 2019., 2019 We reprocessed existing amino sugar data, published between 1996 and 2018 from global agricultural, grassland, and forest ecosystems in temperate zones, by scaling them up to microbial necromass carbon. On average, microbial necromass abundance increased in the order agricultural < grassland < forest, while its contribution to soil organic carbon (SOC)

Pore‐Scale Coupling of Flow, Biofilm Growth, and Nutrient Transport: A Microcontinuum Approach
Water Resources Research, Volume 60, Issue 11, November 2024.Abstract Biofilms are microbial communities that influence the chemical and physical properties of porous media. Understanding their formation is essential for different topics, such as water management, bioremediation, and oil recovery. In this work, we present a pore‐scale model for biofilm dynamics that is fully coupled with fluid flow and transport

International microbiology : the official journal of the Spanish Society for Microbiology, 2007 Protists, mainly ciliates, play several essential roles in biological wastewater treatment, such as the transfer of matter and energy, bacterial predation, and the removal of organic material. Moreover, during the treatment process, the formation of bioaggregates-flocs and biofilms-is essential to obtaining high-quality effluents. In the present study,
