Quantum Hall conductance of two-terminal graphene devices [PDF]
, 2008 Measurement and theory of the two-terminal conductance of monolayer and bilayer graphene in the quantum Hall regime are compared. We examine features of conductance as a function of gate voltage that allow monolayer, bilayer, and gapped samples to be ...

Using magnetic stripes to stabilize superfluidity in electron-hole double monolayer graphene
, 2015 Experiments have confirmed that double monolayer graphene cannot generate finite temperature electron-hole superfluidity. This has been shown to be due to very strong screening of the electron-hole pairing attraction.

Gate-controlled conductance through bilayer graphene ribbons [PDF]
, 2010 We study the conductance of a biased bilayer graphene flake with monolayer nanoribbon contacts. We find that the transmission through the bilayer ribbon strongly depends on the applied bias between the two layers and on the relative position of the ...

Synthesis of Two Compounds with Self-Assembled Monolayer Properties: Riboflavin 2', 3', 4' , 5' Tetra Octadecanoate & Bis (Phosphatidyl Ethanol) Protoporphyrin IX Amide [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2011 Riboflavin and protoporphyrin IX are two molecules that participate in oxidation and reduction reactions in the living cell. Changing some functional groups of riboflavin and protoporphyrin IX can provide compounds with self-assembled monolayer ...

The chemistry of La on the Si(001) surface
, 2004 This paper reports state-of-the-art electronic structure calculations of La adsorption on the Si(001) surface. We predict La chains in the low coverage limit, which condense in a stable phase at a coverage of 1/5 monolayer.

Vanadium oxide monolayer catalysts. I. Preparation, characterization, and thermal stability [PDF]
, 1979 Vanadium oxide catalysts of the monolayer type have been prepared by means of chemisorption of vanadate(V)-anions from aqueous solutions and by chemisorption of gaseous V2O3(OH)4.

Mechanisms of parasite‐mediated disruption of brain vessels
FEBS Letters, EarlyView.Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Hydrodynamics of Monolayer Domains at the Air-Water Interface
, 1996 Molecules at the air-water interface often form inhomogeneous layers in which domains of different densities are separated by sharp interfaces. Complex interfacial pattern formation may occur through the competition of short- and long-range forces acting
