ARTICLES Mixing in PCBM/P3HT bilayers, using in situ and ex situ neutron reflectivity
In situ and ex situ neutron reflectivity is used to characterize annealed regioregular-P3HT/PCBM bilayers. In situ annealing of a 20 nm PCBM/35 nm P3HT bilayer at 170 °C reveals rapid mixing of PCBM and P3HT to produce a polymer-rich layer that contains around 18–20% PCBM. Samples with three different thicknesses of P3HT layer are ex situ annealed at 140 °C. This again reveals migration of PCBM...
متن کاملFabrication of Ti3SiC2-SiC max phase composites via in-situ and ex-situ synthesis
Recently, a series of three-component compounds with the combination of Mn+1AXn known as Max phases have been considered as a new material. One of the most important features of Max phases, is the self-healing property of them. The main reason for considering Max Phases is a unique collection of unusual properties including their metallic, ceramic, physical, and mechanical properties. One of th...
متن کاملIntegrating Ex situ and In situ Conservation of Lemurs
Site-based and cross-regional habitat and species conservation e!orts in Madagascar, such as proposed in the previous chapters of this Lemur Conservation Strategy, should always be the main focus of lemur conservation. However, with many wild lemur populations rapidly declining and their habitat being lost at constantly high rates, captive assurance colonies are becoming increasingly important,...
متن کاملα-Synuclein insertion into supported lipid bilayers as seen by in situ X-ray reflectivity.
Large aggregates of misfolded α-synuclein inside neuronal cells are the hallmarks of Parkinson's disease. The protein's natural function and its supposed toxicity, however, are believed to be closely related to its interaction with cell and vesicle membranes. Upon this interaction, the protein folds into an α-helical structure and intercalates into the membrane. In this study, we focus on the c...
متن کاملGraphene oxide hydration and solvation: an in situ neutron reflectivity study.
Graphene oxide membranes were recently suggested for applications in separation of ethanol from water using a vapor permeation method. Using isotope contrast, neutron reflectivity was applied to evaluate the amounts of solvents intercalated into a membrane from pure and binary vapors and to evaluate the selectivity of the membrane permeation. Particularly, the effect of D2O, ethanol and D2O-eth...
