Molecular Mechanism of Physical and Mechanical Improvement in Graphene/Graphene Oxide-Epoxy Composite Materials.

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.

Association between graft function and serum TNF-α, TNFR1 and TNFR2 levels in patients with kidney transplantation.

Introduction: This prospective observational study aimed to assess the relevance of serial postoperative serum TNF-α, TNFR1 and TNFR2 measurements for predicting graft function and acute rejection episodes (AR) after transplantation.

Materials And Methods: We studied 50 kidney transplant recipients (31 female, 19 male; mean age: 38.36 ± 12.
