“…As previously shown in Figure , at a sulfonation level of 20 mol %, no peak was observed in the SANS data of the blends, which would correspond to complete suppression of the concentration fluctuations between the complexation points, though the low- q intensity upturn seen in the SANS in Figure does indicate that large concentration fluctuations persisted in that system. A similar result was reported by Zhou et al , for blends exhibiting intermolecular hydrogen bonding. 6 Schematic of the effect of sulfonation level of the ionomer on the suppression of concentration fluctuations between complexation points.…”

“…Polymer blends are most often immiscible due to the small combinatorial entropy of mixing for high molecular weight compounds. Miscibility can be achieved by promoting intermolecular exothermic interactions such as hydrogen bonding, − ion−dipole interactions, acid−base interactions, and transition metal complexation…”

“…Polymer blends are most often immiscible due to the small combinatorial entropy of mixing for high molecular weight compounds. Miscibility can be achieved by promoting intermolecular exothermic interactions such as hydrogen bonding, [1][2][3][4][5] ion-dipole interactions, 6 acidbase interactions, 7 and transition metal complexation. 8 An increasingly popular strategy for enhancing the miscibility of two polymers is to attach ionic groups to one polymer that form specific attractive interactions with a complementary functional group on the second polymer.…”
Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD).
Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD.
The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC).
Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…The cluster feature at low Q and the typical Gaussian chain scattering at high Q are the dominant features. Following other SANS investigations of similar structures, , a simple, two-correlation-length model was used. The scattered intensity was fitted to the following functional form: The first term is used to describe the low- Q , long-range behavior (∼1/ Q 4 ).…”

“…Among miscible polymer blends, hydrogen-bonded systems have played a prominent role. There exists a great structural variety of miscible hydrogen-bonding polymer pairs. − In particular, a considerable amount of literature concerns the miscibility of poly(4-vinylphenol) (PVPh) with other polymers. − Poly(4-vinylphenol) is a proton donor that has an easily accessible hydroxyl group in the fourth position of the aromatic ring (Figure ). It undergoes strong hydrogen-bonding interactions with proton-acceptor polymers such as poly(ethylene oxide), poly(methyl methacrylate), and poly(vinyl methyl ketone) .…”
