“…This shift to higher Q shows that there is a decrease in the average distance between the micelles with concentration. Similar results have been observed in studies of both anionic hydrocarbon and fluorocarbon surfactants [40,41].…”

All FC surfactants in this study generate very low surface tensions (< 20 mN m) which are comparable, and in some cases, lower than fully-fluorinated surfactant analogues. The complementary techniques (tensiometry and NR) allowed direct comparison to be made with NaPFO in terms of adsorption parameters such as surface excess and area per molecule. Surface tension data for these technical grade FC surfactants were not amenable to reliable interpretation using the Gibbs adsorption equation, however NR provided reliable results. SANS has highlighted how changes in surfactant head group structure can affect bulk properties. This work therefore provides fresh insight into the structure property relationships of some industrially relevant FC surfactants, highlighting properties which are essential for development of more environmentally friendly replacements.

Presented here are the results for a novel class of hydrocarbon surfactants, termed trimethylsilyl hedgehogs (TMS-hedgehogs), due to the presence of silicon in the tails. By comparing the surface properties of these hybrid hedgehogs to purely hydrocarbon equivalents, links between performance and the structure are made. Namely, by controlling the molecular volume of the surfactant fragments, improvements can be made in surface coverage, generating lower surface energy monolayers. Small-angle neutron scattering (SANS) data have been collected showing that these novel surfactants aggregate to form ellipsoidal micelles which grow with increasing concentration. This study highlights the sensitive relationship between surface tension and the surfactant chain, for designing new super-efficient surfactants close to the limit of the lowest surface tensions possible.

“…The scattering data from BATAN had been analysed and fitted using data analysis program for micellar structure. Here, we obtained that the shape of the 0.3 M SDS is elongated with the ratio of minor and major axes about 1:1.65 and formed by ~ 100 of SDS molecules [10]. The linearity of the detector was evaluated by carrying out SANS measurement of incoherent scattering from water of 1 mm thick at sample-to-detector distance of 1.5 m for 24 hours.…”

DESIGN AND CONSTRUCTION OF THE CONTROL SYSTEM FOR BATAN SMALL ANGLE NEUTRON SCATTERING SPECTROMETER (SMARTer). A 36 m Small Angle Neutron Scattering (SANS) Spectrometer (SMARTer) has been installed in Serpong, Indonesia in 1992. As time goes by, the original main computer was out of order and the instrument had not been operated since 2003. In order to activate the SMARTer, in the year 2005, a work on designing and constructing a new control system for SMARTer was carried out. The main component of this control system is a programmable peripheral I/O (IC PPI 8255) and was assembled as a plug-in board at an ISA slot of a personal computer. An IC PPI 8255 was programmed to control the mechanical movements of the instrument's components: four neutron guide tubes, six pinholes collimator, a detector and a beam stopper. The test either with or without neutron beam has shown that this control system can be implemented for the mechanical movements of SMARTer. Error of moving the detector in the distance range of 1.5 m-18 m is only 1 mm and the other movements have no error at all (precise).
