Witryna28 lut 2024 · Recently, strong evidence that supports the presence of an intramolecular C−H···O hydrogen bond in amides derived from the chiral auxiliary α-methylbenzylamine was disclosed. Due to the high importance of this chiral auxiliary in asymmetric synthesis, the inadvertent presence of this C−H···O interaction may lead to new interpretations … Witryna4 godz. temu · Janus transition-metal dichalcogenide monolayers are artificial materials, where one plane of chalcogen atoms is replaced by chalcogen atoms of a different type. Theory predicts an in-built out-of-plane electric field, giving rise to long-lived, dipolar excitons, while preserving direct-bandgap optical transitions in a uniform potential …

WitrynaThe original motion of the atoms was in all directions—it was a sort of “vibration”; hence there resulted collisions and, in particular, a whirling movement, whereby similar atoms were brought together and united … WitrynaThe formation of TIC was initially understood to be the result of dedifferentiation of mature cells. Nowadays, it has been realized that as long as adequate mutations are accumulated, proliferating cell at any differentiation stage can become a TIC. Moreover, evidence of multi-lineage origin has been piled up in tumors of multiple systems. 1, 2
