Evidence by ac-conductivity for the higher mobility of boron (over aluminium)-associated Brønsted sites in boron-modified HZSM-5
Published 1996“…Therefore, for this particular sample the electric data have been discussed in greater detail. Ruling out the perturbing role of dc-conduction, by analysis at both high frequencies and low temperatures where the dc-conduction is minimum, reveals conductivity increasing in the order: B1ZSM-5<B2ZSM-5<B3ZSM-5<B4ZSM-5 and activation energy decreasing in the order: B1ZSM-5>B2ZSM-5>B3ZSM-5>B4ZSM-5. …”

Spectrofluorometric investigations on the solvent effects on the photocyclization reaction of diclofenac
Published 2023“…The solvent effects were qualitatively and quantitatively assessed employing various solvatochromic models, including multi-parameter linear regression analysis (MLRA). Interestingly, the MLRA results (R = 0.99) revealed that the photoconversion rate increases with increasing solvent polarizability (π*) and H-bond donor capability (α), whereas the rate decreases with increasing hydrogen-bond acceptor capability (β). …”
