Pt-doped armchair graphene nanoribbon as a promising gas sensor for CO and CO<sub>2</sub>: DFT study
منشور في 2021"…To enhance the sensing performance, both H-AGNR and N-AGNR systems were doped with platinum (Pt) forming another two systems: Pt–H-AGNR, and Pt–N-AGNR. After doping, the results revealed a significant increase in the adsorption energy to almost 9 times than the non-doped systems for the cases of CO on Pt–N-AGNR as well as CO<sub>2</sub> on both Pt–H-AGNR and Pt–N-AGNR. …"

Durability of the bond between CFRP plates and concrete exposed to harsh environment
منشور في 2014"…Single-lap shear tests were conducted on all specimens after exposure to failure of the specimens. It was observed that the specimens exposed to the sun and saline environments experienced an increase in both the bond strength and attained peak loads because exposure of the adhesive to elevated temperature increased the bond because of greater polymer crosslinking, thus creating complex interactions in the polymer matrix. …"
