“…The second stage (decomposition phase) occurs up to 400°C, with the weight loss attributed to the breakage of polymer chains, such as hydrogen bonds in PVA and CS and ether bonds in CS. Finally, the degradation phase involves the breakdown of polymer backbone chains [37][38][39]. The remaining weight of the hydrogel is referred to as residue.…”

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.

“…Due to their remarkable physical and chemical properties, zeolites have the potential to serve as ion exchangers, molecular filters, adsorbents, and catalysts. Natural zeolites find extensive use in various applications, such as filtration, hydrogen purification through steam filtration, ethanol refinement, fuel cell membranes, and desalination processes [7][8][9][10][11][12][13][14].…”

“…Another study revealed that its presence increased hydrophilicity, water flux, and salt rejection. The important aspect that must be considered when preparing a membrane with zeolite as a nanofiller is the filler dispersion quality [ 8 , 9 , 10 , 11 , 12 ].…”
