Role of hydrogen in chemical vapor deposition growth of large single-crystal graphene.
We show that graphene chemical vapor deposition growth on copper foil using methane as a carbon source is strongly affected by hydrogen, which appears to serve a dual role: an activator of the
Water desalination using nanoporous single-layer graphene.
It is shown that single-layer porous graphene can be used as a desalination membrane using an oxygen plasma etching process and exhibits a salt rejection rate of nearly 100% and rapid water transport.
Graphene Nucleation Density on Copper: Fundamental Role of Background Pressure
In this paper we discuss the effect of background pressure and synthesis temperature on the graphene crystal sizes in chemical vapor deposition (CVD) on copper catalyst. For the first time, we
Porous graphene as the ultimate membrane for gas separation.
Porous graphene sheets are proposed as one-atom-thin, highly efficient, and highly selective membranes for gas separation, which could have widespread impact on numerous energy and technological applications; including carbon sequestration, fuel cells, and gas sensors.
Quantum mechanical basis for kinetic diameters of small gaseous molecules.
The quantum mechanical (QM) diameters of several common gaseous molecules are obtained by determining the cross-sectional sizes of their iso-electronic density surfaces at a predetermined small value and it is shown that the QM diameters are in good agreement with the kinetic diameters.
Carbon Materials for Chemical Capacitive Energy Storage
In order to further improve the power and energy densities of the capacitors, carbon-based composites combining electrical double layer capacitors (EDLC)-capacitance and pseudo-Capacitance have been explored and show not only enhanced capacitance, but as well good cyclability.
Antiwear performance and mechanism of an oil-miscible ionic liquid as a lubricant additive.
An ionic liquid (IL) trihexyltetradecylphosphonium bis(2-ethylhexyl) phosphate has been investigated as a potential antiwear lubricant additive and a protective boundary film is believed to be responsible for the IL's antiscuffing and antiwear functionality.
pH-Responsive polymers: synthesis, properties and applications.
Several polymeric systems, such as homopolymers, block copolymers, microgels, hydrogels and polymer brushes at interfaces are reviewed, where important characteristics that govern their behavior in solutions are described.
Carbon dioxide capture by superbase-derived protic ionic liquids.
PILs from a superbase and fluorinated alcohol, imidazole, pyrrolinone, or phenol are capable of rapid and reversible capture of about one equivalent of CO{sub 2}, which is superior to those sorption systems based on traditional aprotic ILs.
Low-Pressure Solubility of Carbon Dioxide in Room-Temperature Ionic Liquids Measured with a Quartz Crystal Microbalance
The solubility of carbon dioxide in a series of imidazolium-based room-temperature ionic liquids has been determined using a quartz crystal microbalance. Henry's constants were obtained for CO2 in
