Integrating agro‐residue valorization and clean hydrogen production: coconut fiber‐based catalysts for NaBH4 hydrolysis

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract A novel phosphoric acid‐treated green coconut fiber (GCF‐C) was developed as a catalyst for hydrogen production from the hydrolysis of sodium borohydride (NaBH4). Characterization techniques confirmed structural modifications, including X‐ray diffraction, scanning electron microscopy, X‐ray fluorescence, Fourier transform infrared, and ...

Study of the Effect of MMC on the Sister Chromatid Exchange in the Human Lymphocytes [PDF]

Journal of Kerman University of Medical Sciences, 2004
Some environmental mutagenic agents cause genomic instability and increase susceptibility of DNA damage. One of them is mitomycin C which is connected to DNA as an alkylating factor and affects susceptible cells to reduction reactions.

The Synthesis Effects on the Performance of P2‐Na0.6Li0.27Mn0.73O2 Cathode Material for Sodium‐Ion Batteries

Battery Energy, Volume 4, Issue 2, March 2025.
The effect of reagents on the structure and performance of sodium‐layered oxides has not yet been thoroughly studied. This work explored this factor systematically through in situ high‐temperature XRD. The samples synthesized via MnCO3‐based precursors form the Li2MnO3 phase at evaluated temperature and perform better than those through MnO2‐based ...

Amorphous Protective Layers to Reshape Inorganic‐Rich Interphases for High‐Voltage Sodium‐Ion Batteries

Carbon Energy, EarlyView.
Herein, we propose a straightforward and efficacious strategy of surface modification for P2‐type Na0.7Li0.03Mg0.03Ni0.27Mn0.6Ti0.07O2 cathode in high‐voltage Na‐ion batteries. The stable amorphous SiO2 coating layer on the cathode surface contributes to a strong, dense, fluorine and silicon‐rich cathode–electrolyte interphase, which inhibits the side ...
