Here, we evaluate the nanostructure-activity relationship in twisted bilayer graphene by modeling it under the scanning electrochemical cell microscopy setup to resolve its spatial moiré domains. We solve the steady state ion transport inside a 3D nanopipette to isolate the current response at AA and AB domains. Interfacial reaction rates are obtained from a modified Marcus-Hush-Chidsey theory combining input from a tight binding model that describes the electronic structure of bilayer graphene. High rates of redox exchange are observed at the AA domains, an effect that reduces with diminished flat bands or a larger cross-sectional area of the nanopipette. Using voltammograms, we identify an optimal voltage that maximizes the current difference between the domains.

However, these devices often face challenges such as instability in electroluminescence spectra and low brightness due to phase segregation in mixed-halide perovskites. Here, we demonstrate spectrally stable and bright red perovskite LEDs by substituting some of the halide ions with pseudohalogen thiocyanate ions (SCN<sup>-</sup>). We find that SCN<sup>-</sup> can occupy halogen vacancies, thereby releasing microstrain and passivating defects in the perovskite crystals. This leads to the suppression of mixed-halide phase segregation under electrical bias. As a result, the red perovskite LEDs exhibit a high brightness of >35 000 cd m<sup>-2</sup> with stable Commission Internationale de l'Eclairage (CIE) coordinates of (0.713, 0.282).

The strong quantum and dielectric confinements are shown to squeeze the biexciton under the polaronic radius, which greatly enhances Coulomb attractions and (to a lesser extent) repulsions. This explains the need for effective dielectric constants approaching the high-frequency limit in previous simulations, and the binding energies exceeding 40 meV observed in single-monolayer nanoplatelets. Biexcitons are formed by a pair of weakly interacting excitons, with a roughly rectangular geometry. This translates into a constant ratio between biexciton and exciton binding energies (2D Haynes rule) well below the ideal value of Δ<sub>BX</sub>/Δ<sub>X</sub> = 0.228 proposed for squared biexcitons.

Here, we present a novel method for obtaining conformation-selective ultraviolet (UV)–UV hole burning (HB) spectra of ubiquitin ions ((Ubi+zH)<sup>+z</sup>, z = 7–10) produced via electrospray ionization. Our approach involves binding multiple N<sub>2</sub> molecules to ubiquitin ions ((Ubi+zH)<sup>+z</sup>(N<sub>2</sub>)<sub>m</sub>, m = 1–55) within a cryogenic ion trap. Upon exposure to UV irradiation, efficient fragmentation of (Ubi+zH)<sup>+z</sup>(N<sub>2</sub>)<sub>m</sub> occurs, primarily yielding bare (Ubi+zH)<sup>+z</sup> ions as fragments. The significant mass difference between the parent and fragment ions facilitates the acquisition of UV–UV HB spectra, which reveal the presence of at least two distinct conformers. Molecular dynamics simulations suggest that these conformers correspond to A-state structures, differing only in the interactions of a tyrosine residue with neighboring residues. Our findings underscore UV–UV HB spectroscopy of protein ions as a powerful tool for exploring diverse protein isomers.","PeriodicalId":62,"journal":{"name":"The Journal of Physical Chemistry Letters","volume":null,"pages":null},"PeriodicalIF":6.475,"publicationDate":"2024-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141597425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared to QED-driven radiative ET rates in free space, plasmonic cavities induce substantial rate enhancements spanning the range from 10<sup>3</sup>- to 10-fold. By contrast, Fabry–Perot cavities engender rate suppression spanning the range from 10<sup>–2</sup>- to 10<sup>–1</sup>-fold.
