Evidence by ac-conductivity for the higher mobility of boron (over aluminium)-associated Brønsted sites in boron-modified HZSM-5 حسب Sayed, Moein B.

"…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. …"

Investigation of Spatiotemporal Variability of Microplastics in Qatar's Cstal Environment حسب Ben-Hamadou, Radhouane

"…Microplastics are tiny plastic particles that seldom originate from fragmentation of large plastic debris or are produced to serve some specific purposes. Microplastics pose greater threats as they can be mistaken for food by filter-feeders and planktivorous fish, and can also adsorb large quantities of recalcitrant organic pollutants (OPs). …"
