Flash reduction of graphene oxide is an efficient method for producing high quality reduced graphene oxide under room temperature ambient conditions without the use of hazardous reducing agents (such as hydrazine and hydrogen iodide). The entire process is fast, low‐cost, and suitable for large‐scale fabrication, which makes it an attractive process for industrial manufacturing. Herein, we present a simple fabrication method for a flexible in‐plane graphene micro‐supercapacitor using flash light irradiation. All carbon‐based, monolithic supercapacitors with in‐plane geometry can be fabricated with simple flash irradiation, which occurs in only a few milliseconds. The thinness of the fabricated device makes it highly flexible and thus useful for a variety of applications, including portable and wearable electronics. The rapid flash reduction process creates a porous graphene structure with high surface area and good electrical conductivity, which ultimately results in high specific capacitance (36.90 mF cm−2) and good cyclic stability up to 8,000 cycles.
We investigated the neuropsychological profile of subjects in a subclinical obsessive-compulsive disorder (OCD) sample. Psychometrically defined subclinical obsessive-compulsive (n = 21) and control (n = 22) subjects were examined. Comprehensive neuropsychological tests evaluating verbal/nonverbal memory, attention, and executive function were administered. The subclinical obsessive-compulsive group showed poorer performances on the Wisconsin Card Sorting Test (WCST), F(1, 41) = 13.80, p < .001, and Trail-Making Test (TMT), F(1, 41) = 5.48, p < .05, compared with the control group. The subclinical obsessive-compulsive group showed higher rates of total errors, perseverative errors, and perseverative responses. In addition, the subclinical obsessive-compulsive group committed a greater number of errors in the TMT. However, the groups showed no performance differences in the TMT after controlling for the effects of depression and anxiety, F(1, 39) = 0.11, p = .739. These results suggest that subclinical obsessive-compulsives seemed to display deficits in executive functioning. This neuropsychological profile is consistent with current theories proposing that executive dysfunction may serve as the pathophysiological mechanism underlying the development of obsessive-compulsive disorder.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
