Comparative Evaluation of HFC‐134a Decompositions Over Metal‐Impregnated γ‐Al2O3 Catalysts (M/γ‐Al2O3) (M = Mg, Ni, Co, Zn, Cu)

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This study examines the impact of an impregnated metalon the structural alterations of the catalyst induced by intermediatesgenerated during the HFC‐134a catalytic decomposition reaction. Through adetailed analysis of the catalyst before and after the reaction, the underlyingcause of the observed inactivity is elucidated.

A cross‐sectional clinical study in women to investigate possible genotoxicity and hematological abnormalities related to the use of black cohosh botanical dietary supplements

open access: yesEnvironmental and Molecular Mutagenesis, Volume 63, Issue 8-9, Page 389-399, December 2022., 2022
Abstract Black cohosh (BC; Actaea racemosa L.), a top‐selling botanical dietary supplement, is marketed to women primarily to ameliorate a variety of gynecological symptoms. Due to widespread usage, limited safety information, and sporadic reports of hepatotoxicity, the Division of the National Toxicology Program (DNTP) initially evaluated BC extract ...

Metal Sulfides as Potential Materials for Next Generation Lithium Ion Batteries: A Review

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
The flame spray pyrolysis (FSP) method demonstrates its superiority in fabricating metal sulfide‐based electrodes without inactive materials like organic binders or solvents. The particles are directly deposited and compressed onto the electrode surface, integrating into continuous production.
