High-pressure hydrogenation of graphene : towards graphane
Published 2013“…We present here a scalable method for the hydrogenation of graphene based on thermal exfoliation of graphite oxide in a hydrogen atmosphere under high pressure (60–150 bar) and temperature (200–500 °C). This method does not require a plasma source and is able to produce gram quantities of the material. …”

Fabrication of hollow fiber membranes using amphiphilic block copolymers as pore-forming additives
Published 2014“…When Pluronic F127 concentration was 10 wt%, the as-spun hollow fiber exhibited the highest PWP of 114 L/m2•h•bar and the lowest MWCO of 9 kDa. Due to the good performance of Pluronic F127 in PES membrane fabrication, it has been selected as the amphiphilic additive to further study the formation of poly(vinylidene fluoride) (PVDF) membranes. …”

Clouds and hazes in Saturn's troposphere and stratosphere
Published 2013“…Near-infared VIMS data between 4.5 and 5.1 <em>μ</em>m are mainly sensitive to deeper tropospheric levels down to approximately 5 bar. At such pressure levels, thermochemical models predict the formation of condensed clouds made of ammonia and ammonium hydrosulphide ices, although none of these species has been spectrally detected so far. …”
