The performance provided by graphene (Gr) and graphene oxide (GO) additives can be improved by achieving strong adhesion and uniform dispersion in the epoxy resin matrix. In this study, molecular modeling and simulation of DGEBA/DETA based epoxy nanocomposites containing Gr and GO additives were performed. Density functional theory and molecular dynamics simulations were used to investigate interfacial interaction energies and Young's Modulus.

Purpose: The aim of this study was to explore the relationship between spousal support perceived by those with COPD and their activities of daily living.
Methods: This study was a cross-sectional and descriptive study.
Purpose: The use of transvaginal natural orifice transluminal endoscopic surgery (vNOTES) as the first choice of surgical route for patients scheduled to undergo conventional laparoscopy is still being debated. We aimed to evaluate and compare the outcomes of the "vNOTES first" strategy in benign gynecological cases.
Methods: All benign gynecological surgeries were initiated using vNOTES during the study period, regardless of the difficulty.
Objective: To present coronavirus disease-2019 (COVID-19) related maternal mortality in relation to Delta and Omicron waves and to investigate the role of lung ultrasound (LUS) in estimating mortality.
Materials And Methods: This retrospective cohort study was conducted in the obstetrics and gynecology clinic of a tertiary pandemic hospital between March 2020 and January 2022. The hospitalized pregnant women with COVID-19 diagnosis and maternal deaths were studied in relation with Delta and Omicron waves.
