Effect of Graphene Oxidation Rate on Adsorption of Poly-Thymine Single Stranded DNA

Effect of Graphene Oxidation Rate on Adsorption of Poly‐Thymine Single Stranded DNA

Representative snapshots illustrating how surface oxidation rate can affect conformational changes of prefolded poly(T)20 on graphene surfaces. In the case of the surface with low or high oxidation rate, strong van der Waals or electrostatic interactions make poly(T)20 unstable. However, on graphene oxide with moderate oxidation rate, poly(T)20 has a good structural retention due to balanced nonbonded interactions.

Graphene–Mesoporous Si Nanocomposite as a Compliant Substrate for Heteroepitaxy

A graphene–porous silicon nanocomposite is proposed for a novel concept of tunable compliant substrate for epitaxy, which extends the range of available lattice constants for epitaxial semiconductor alloys.

Controlled 3D Assembly of Graphene Sheets to Build Conductive, Chemically Selective and Shape‐Responsive Materials

Using pristine, natural flake graphene as a 2D surfactant to stabilize water-in-oil emulsions, polymer foams are formed that selectively swell in various solvents and demonstrate changes in resistivity with deformation. Graphite exfoliation and templated polymerization is enabled by the surface activity of graphene, and is driven by graphene spreading at high energy interfaces to lower the overall energy of the system.

Confining Cation Injection to Enhance CBRAM Performance by Nanopore Graphene Layer

Confining Cation Injection to Enhance CBRAM Performance by Nanopore Graphene Layer

Excessive cation injection into a resistive switching layer beyond the requirement of conductive filament formation, leads to deterioration of conductive-bridge random access memory (CBRAM) performance. The cation injection can be localized by inserting a nanohole graphene between active electrode and resistive switching layer. The nanoscale localized cation injection, validated by conductive atomic force microscopy, gives rise to enhanced CBRAM performance.
