in the current work, graphene oxide (go) samples were prepared at room temperature from graphite flakes using a modified hummer's method to produce metal-free electrocatalysts. the effect of the duration of the oxidation process on the structural, chemical and physical characteristics of the go samples was evaluated using x-ray diffraction (xrd), fourier transform infrared spectroscopy (ftir), ...

the aim of this study was to optimize the encapsulation conditions of garlic oil (go) with β-cyclodextrin (go/β-cd) inclusion complex by the co-precipitation method. response surface optimization of encapsulation of go with β–cd was performed with a three-variable, three-level and the optimum conditions were as follows: temperature: 35oc, core/wall: 8/100, and wall/solvent: 5.5/100. the complex...

Graphene oxide/Ag nanoparticles (Ag/GO) was prepared and employed to synthesize antifouling polyethersulfone (PES) mixed matrix membranes. The performance of the membranes was evaluated in terms of flux, hydrophilicity and anti-biofouling properties. With increment of the Ag/GO from 0 to 0.1 wt.%, the pure water flux increased from 24.7 up to 54.1 kg/m2 h. The flux recovery ratio (FRR) of the m...

   In this study, effect of asymmetric functionalized graphene oxide (Janus GO) on Young′s modulus and glass transition temperature of Polysulfone (PSf) ultrafiltration membranes was investigated. The membranes were prepared via phase inversion method and GO nanosheets were dispersed in casting solution by sonication. Results showed that the Normalized Young’s modulus (on the basis of neat ...

Sosyal sorumluluk ve çevreyi esas alan sürdürülebilirlik kavramı son yıllarda önemli hale gelmiştir. Bu anlamda kurumların sürdürülebilirliğinin ölçümü önem kazanmış, sürdürülebilirliği ölçmeye yönelik performans tabanlı teknikler ortaya çıkmıştır. ölçümlerinden biri de Sürdürülebilirlik Balans Skor Kart (SBSK) yaklaşımıdır. çalışmanın amacı, (SBm SK)’ın beş boyutlu formunu bir sağlık kurumu ol...
