Article
While hybrid perovskite solar cells (HPSCs) currently reach an efficiency as high as 25.8% and are comparable with commercial silicon solar cells, they still suffer from low stability against external environmental conditions. The best way to protect the perovskite active layer from degradation caused by humidity is the development of dopant‐free o...
Article
In this study, a series of new1,2,5-oxadiazole compounds derived from 4-chloro-7-nitro-benzo 1,2,5-oxadiazole was synthesized using different organic procedures. The resulting derivatives were chemically characterized and their structures were confirmed by FT-IR and NMR analysis. All the compounds were also evaluated for their antibacterial and ant...

In this paper, a series of new compounds were synthesized, yielding four compounds including two schiff bases. This compounds were synthesized from hetero cyclic isatin with 5-Amino-1,3,4-thiadiazole-2-thiol (I1-I4). Condensation of I2 compound with aromatic aldehydes such as 4-nitro benzaldehyde and 4-hydroxy benzaldehyde yielded schiff bases (I3...

In this work, the photo-stabilization of poly (vinyl chloride) was studied using new compounds such as Schiff base stabilizers derived from heterocyclic compounds, with symbols [I1-I4] which were used as additives to prevent the PVC photodegradation. Many samples have been prepared as films for this purpose by adding the additives to poly (vinyl ch...
Article
Perovskite materials, due to their excellent photovoltaic features, have aroused the researchers′ admiration as a photon-absorption film for the next-generation photovoltaics. The interface tailoring of perovskites and hole-transport layer (HTL) is one of the critical approaches to achieve effective and stabilized perovskite solar cell (PSC). Hence...

A prosthetic eye may enhance the appearance of individuals who have lost sight due to injury or illness. Implanting a polymeric ocular prosthesis (POP) after an eye is surgically removed following an enucleation, evisceration, or orbital exenteration is always advised. This implant supports proper eyelid functioning as well as increasing patient co...

The photostabilization of poly vinyl chloride (PVC) films has been investigated by using diamine derivatives. The (PVC) films were contained 0.5% weight of diamine derivatives which prepared by the method of casting. The photostabilization of these compounds were determined by monitoring the carbonyl index value with irradiation time. Also, the eff...
