WebAbstract. ZnGeP 2 (ZGP) crystals have attracted tremendous attention for their applications as frequency conversion devices. Nevertheless, the existence of native point defects, including at the surface and in the bulk, lowers their laser-induced damage threshold by increasing their absorption and forming starting points of the damage, limiting ... WebApr 19, 2024 · Abstract: Perfect crystals are rare in nature. Real materials often contain crystal defects, surface reconstructions, nanoscale heterogeneities and disorders, which strongly affect material properties and functionality. Although aberration-corrected electron microscopy has been broadly used to characterize crystal defects at sub-angstrom …

WebAbstract Herein, we describe an effective strategy for enantioselective synthesis of oxindoles having C3-quaternary stereocenter via N-heterocyclic carbene (NHC) catalyzed desymmetrization of diol. The process is based on the catalytic asymmetric transfer acylation of primary alcohol using readily available aldehyde as acylation agent. WebGraphical Abstract.
