“…[ 20 ] Since the observed COF after γ‐sterilization is comparable to the one of non‐sterilized samples (Figure 1A), the lubricant seems to be either no longer present on the surface or no longer present in its original molecular structure. In literature this effect was also seen by Demertzis et al, [ 35 ] who found erucamide to degrade in LDPE and PP after γ‐radiation with 44 kGy. They also were not able to detect the resulting degradation products by GC/MS analysis.…”

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.

“…For instance, the polytetrauoroethylene (PTFE) coating used to promote hydrophobicity in the GDE cathode and other polymeric materials (e.g., membranes) is known to undergo radiation-induced degradation. [44][45][46][47] This deterioration may affect the hydrophobic characteristics that prevents cathode ooding, for instance. The loss of hydrophobicity may have affected the selectivity towards CO conversion, as can be observed in the preferential increase in the H 2 generation (Fig.…”

“…DTBB was identified via MS using the NIST library search. Based on this match, it is assumed to be a radiolysis product of Irgafos 168, which can only be detected in irradiated samples 13,14,16 . Since a comparative measurement was assumed sufficient, no internal standard was used.…”
