Abstract Constipation is a common but not a universal feature in early PD, suggesting that gut involvement is heterogeneous and may be part of a distinct PD subtype with prognostic implications. We analysed data from the Parkinson’s Incidence Cohor

Small-angle neutron scattering spectrometry has been used to study the geometry of mixed cationic/nonionic micelles of hexadecyltrimethylammonium bromide (C16TAB) and hexaethylene glycol monododecyl ether (C16E6). The anisotropic interacting micelles

Small-angle neutron scattering, SANS, has been used to characterize the adsorption of hexaethylene glycol monododecyl ether (C12E6) on silica sols. The results presented here describe the effects of temperature on the nature of the adsorbed layer and

Small-angle neutron scattering (SANS) has been used to investigate the geometry of micelles of the poly(oxyethylene) nonionic surfactants C16E6 and C16E8 aligned in situ in a shear flow, in the presence of 'salting in' or 'salting out' electrolyte. W

The specular reflection of neutrons is now finding widespread application in a range of problems in surface chemistry. Recent studies have shown that by the use of hydrogen-deuterium isotopic substitution, it is possible to determine surface excesses

A cosmetic product is often a complex non-homogeneous mixture of physicochemical units including polymers, small molecules, surface-active species, and particles. In use, it is applied to an equally heterogeneous substrate, skin. Consequently, materi

A mid-infrared laser technique is described for the accurate determination of water vapor concentration in the headspace above a liquid sample. The method is based on the measurement of the fractional absorption, at line center, of a single ro-vibrat
