Three novel gold nanoparticle (AuNPs) composites protected by perylene bisimide derivatives have been designed and synthesized. Thanks to the rational molecular design, AuNPs capped by N,N'-2,6-bis(4-aminomethylpyridine)-1,6,7,13-tert-[4-(hydroxymethyl)phenoxy-5-(1,2-dithiolan-3-yl)pentanoate]-3,4,9,10- tetracarboxylic acid bisimide (8SP-AuNPs) exhibited unusual enhancement in fluorescence inte...
the purpose of the present study was to determine whether noticing through input enhancement had any impact on the acquisition of english conditional sentences in iranian efl learners. two intact classes with 26 female students in each were chosen. a proficiency test administered at the commencement of the study showed that the two groups were homogeneous in terms of their language proficiency....
We newly synthesized various sized gold nanoparticles covered with photochromic polymers consisting of diarylethenes with various structures to investigate an effect of the gold nanoparticles on the photocycloreversion reaction of the diarylethene chromophores upon irradiation with visible light. The gold nanoparticles covered with the photochromic polymers exhibited reversible changes in local...
Graphene is known as the strongest 2D material in nature, yet we show that moderate charge doping of either electrons or holes can further enhance its ideal strength by up to ~17%, based on first-principles calculations. This unusual electronic enhancement, versus conventional structural enhancement, of the material's strength is achieved by an intriguing physical mechanism of charge doping cou...
