Modulating Charge‐Transfer Excited States of Multiple Resonance
Advanced multiple resonance thermally activated delayed fluorescence (MR-TADF) emitters with high efficiency and color purity have emerged as a research focus in developing ultra-high-definition displays. Herein, we disclose an approach to modulate charge-transfer excited states of MR emitters via intramolecular covalent bond locking.
Imcando hammer
The Imcando hammer is a wieldable variant of a hammer mostly used for Smithing or Construction. Once a player gains access to the Ruins of Camdozaal after completing the Below Ice Mountain quest, they may begin to mine barronite rocks for barronite shards and deposits. Smashing a mined barronite deposit on the Barronite Crusher gives the player …

Multiple internal resonance couplings and quasi-periodicity …
1. Introduction. Internal resonance (IR), characterized mainly by the energy leakage to a new vibrational mode rather than the targeted mode (i.e., excited mode) where the ratio between the involved modes must be commensurate [1, 2], is one of the classical phenomena that continues to attract the interest of the nonlinear dynamic …

Multiple-peak resonance of optical second harmonic …
The SHG spectra of all the four ${TX}_{2}$ were dominated by two-photon resonance around the C peaks in the DR spectra that was previously assigned to interband transitions at critical points formed as a result of band nesting. Multiple peaks were observed in each resonance spectrum, which was then decomposed into a few …

Quantitative assessment of delamination in composites using multiple …
In contrast to the first-order LDR mode, higher-order LDR modes offer better imaging resolution owing to their multiple resonance peaks and a more evenly distributed energy, as depicted in Fig. 2 (b). So, the higher-order LDR one corresponds to more information of the defect boundary [35]. However, on the downside, energy dispersal within the ...
