Brazil, biodiversity has received increasing attention from scientists, governments and the public worldwide. There is growing recognition that the diversity of life on Earth, including the variety of genes, species and ecosystems, is an irreplaceable natural heritage crucial to...

Surface Nanobubbles in Nonaqueous Media: Looking for Nanobubbles in DMSO, Formamide, Propylene Carbonate, Ethylammonium Nitrate, and Propylammonium Nitrate.

An H, Liu G, Atkin R, Craig VS.
PMID: 26153620
ACS Nano. 2015 Jul 28;9(7):7596-607. doi: 10.1021/acsnano.5b02915. Epub 2015 Jul 13.

Surface nanobubbles produced by supersaturation during the exchange of ethanol for water are routinely observed on hydrophobic surfaces, are stable for days, and have contact angles that are very much greater than observed macroscopically. Here, we test the hypothesis...

We report a novel nanofabrication method to fabricate printable integrated circuits with a high refractive index working in the visible wavelength range. The printable planar ligthwave circuits are directly imprinted by ultra-violet nanoimprinting into functional TiO2-based resist on the...

Conformation of poly(ethylene oxide) dissolved in the solvate ionic liquid [Li(G4)]TFSI.

Physical chemistry chemical physics : PCCP

Chen Z, FitzGerald PA, Warr GG, Atkin R.
PMID: 25982736
Phys Chem Chem Phys. 2015 Jun 14;17(22):14872-8. doi: 10.1039/c5cp02033f.

The conformation of 38 kDa PEO in a solvate ionic liquid (SIL), lithium tetraglyme bis(trifluoromethane-sulfonyl)amide ([Li(G4)]TFSI) from dilute to concentrated solution regimes has been determined by small angle neutron scattering and rheology. SANS analysis reveals that [Li(G4)]TFSI is better...

Combined friction force microscopy and quantum chemical investigation of the tribotronic response at the propylammonium nitrate-graphite interface.

Physical chemistry chemical physics : PCCP

Li H, Atkin R, Page AJ.
PMID: 26027558
Phys Chem Chem Phys. 2015 Jun 28;17(24):16047-52. doi: 10.1039/c5cp01952d. Epub 2015 Jun 01.

The energetic origins of the variation in friction with potential at the propylammonium nitrate-graphite interface are revealed using friction force microscopy (FFM) in combination with quantum chemical simulations. For boundary layer lubrication, as the FFM tip slides energy is...

Nanostructure of the Ionic Liquid-Graphite Stern Layer.

ACS nano

Elbourne A, McDonald S, Voïchovsky K, Endres F, Warr GG, Atkin R.
PMID: 26051040
ACS Nano. 2015 Jul 28;9(7):7608-20. doi: 10.1021/acsnano.5b02921. Epub 2015 Jun 15.

Ionic liquids (ILs) are attractive solvents for devices such as lithium ion batteries and capacitors, but their uptake is limited, partially because their Stern layer nanostructure is poorly understood compared to molecular solvents. Here, in situ amplitude-modulated atomic force...

Effect of ion structure on nanoscale friction in protic ionic liquids.

Physical chemistry chemical physics : PCCP

Sweeney J, Webber GB, Rutland MW, Atkin R.
PMID: 24992959
Phys Chem Chem Phys. 2014 Aug 21;16(31):16651-8. doi: 10.1039/c4cp02320j.

The effect of ionic liquid (IL) molecular structure on nanoscale friction has been investigated using colloidal probe Friction Force Microscopy (FFM). The ILs studied were ethylammonium formate (EAF), ethylammonium nitrate (EAN), propylammonium formate (PAF), propylammonium nitrate (PAN), dimethylethylammonium formate...

Tribotronic control of friction in oil-based lubricants with ionic liquid additives.

Physical chemistry chemical physics : PCCP

Cooper PK, Li H, Rutland MW, Webber GB, Atkin R.

Phys Chem Chem Phys. 2016 Aug 24;18(34):23657-62. doi: 10.1039/c6cp04405k.

Atomic force microscopy (AFM) reveals that tribotronic control of friction using an external potential applied to a gold surface is possible for ionic liquid (IL) concentrations as low as 5 mol% in hexadecane. The IL used is trihexyl(tetradecyl)phosphonium bis(2,4,4-trimethylpentyl)phosphinate,...
