Positional 13C enrichment analysis of aspartate determines PEPC activity in vivo

open access: yesNew Phytologist, Volume 248, Issue 1, Page 401-414, October 2025.
Summary Photoautotrophic organisms fix inorganic carbon (Ci) by RIBULOSE‐1,5‐BISPHOSPHATE CARBOXYLASE/OXYGENASE (RUBISCO) and PHOSPHOENOLPYRUVATE CARBOXYLASE (PEPC). Monitoring Ci assimilation rates in vivo is a major challenge in analyzing photoautotrophic metabolism and engineering improved photosynthesis, as conventional methods do not distinguish ...

Thermally Induced Fault Reactivation Controlled by Heating Rate: Implications for Long‐Term Safety Assessment of Deep Geological Repository

open access: yesGeophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract Heat from radioactive decay of nuclear waste disposal in deep geological repositories may thermally load the host rocks containing fractures and faults, potentially causing fault reactivation and induced seismicity. To investigate the effect of heating rate on stability of thermally induced fault slip, we conducted three experiments of ...

Biomass‐Derived Porous Crystalline Calcium‐Silicates Synthesized from Chicken Eggshell Waste Using Organic Amine Templates: A Case Study for Potential Hemostatic Application

open access: yesEuropean Journal of Inorganic Chemistry, Volume 28, Issue 26, September 24, 2025.
Calcium silicate materials are synthesized using eggshell waste as a sustainable calcium source. Quaternary ammonium salts are employed as key structure‐directing agents, favoring the formation of the clay‐like mineral rhodesite with a significantly higher surface area than previously reported. The hemostatic performance of the synthesized materials is

Tuning the Fe‐Oxide Nanoparticle Properties by Playing with Salt Precursors and Camellia sinensis Extract Concentrations

open access: yesChemPhysChem, Volume 26, Issue 18, September 19, 2025.
Functionalized iron‐oxide nanoparticles exhibiting distinct physical characteristics (particle size and magnetic anisotropy) were successfully biosynthesized by modulating the precursor salts and using two different chemical synthesis pathways. By varying salt precursors and precipitating agents, polyphenol‐functionalized γ‐Fe2O3 nanoparticles (NPs ...
