“…This rough surface is probably caused by the interaction between the Ni and the warmed KOH solution which was used to hydrolyze and dissolve the polycarbonate template. This conclusion was proved by the fact that when we employed the dichloromethane to dissolve the template, the surface of Ni nanowires turned out to be very smooth . The adoption of warmed KOH here brings about the increased roughness and hence improves the specific surface area of the Ni NAs electrode.…”

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.

“…current density = 700 mA cm -2 mg -1 vs. at 0.7 V SCE). Guo et al [89] described a method for the preparation of nickel nanowire arrays (NWAs) by electrodeposition on a polycarbonate template. The electrodes exhibited lower onset potentials for urea electrolysis in an alkaline medium compared to flat Ni electrodes.…”

“…3 Recently, urea is also explored as potential hydrogen storage materials, and monitoring of urea concentration may be important in developing highly performing energy storage and conversion systems. 2 Many sensing platforms are based on the use of enzyme to hydrolyze urea for the release of NH 4+ , HCO 3− , and OH − ions. This method can suffer the difficulties associated with enzyme immobilization technique and stability problems caused by denaturation of enzyme.…”

“…3 However, problems related to degradation and expansion of the Ni based catalyst structure during the oxidation still exist. 4 Moreover, nickel's reaction with dissolved oxygen in aerated alkaline solution may result in potential variation driven by formation of Ni(OH) 2 and NiOOH. Such change in concentration of OH − anions is a dominant factor of Ni based catalyst to examine physiological measurement.…”
