Oxygen Reduction at the Liquid–Liquid Interface: Bipolar Electrochemistry through Adsorbed Graphene Layers [PDF]

ChemElectroChem, 2015
AbstractThe reduction of oxygen and protons at the interface between two immiscible electrolyte solutions (ITIES) has received a great deal of interest over the last decade, with various materials being used to catalyse these reactions. Probing the mechanisms through which these reactions proceed when using interfacial catalysts is important from both ...

Protein Adsorption on Various Plasma-Treated Polyethylene Terephthalate Substrates

Molecules, 2013
Protein adhesion and cell response to plasma-treated polymer surfaces were studied. The polymer polyethylene terephthalate (PET) was treated in either an oxygen plasma to make the surface hydrophilic, or a tetrafluoromethane CF4 plasma to make the ...

Strong Photoluminescence Enhancement of MoS2 through Defect Engineering and Oxygen Bonding

, 2014
We report on a strong photoluminescence (PL) enhancement of monolayer MoS2 through defect engineering and oxygen bonding. Micro- PL and Raman images clearly reveal that the PL enhancement occurs at cracks/defects formed during high temperature vacuum ...
