DOI: 10.1007/s11771-019-4174-8
Abstract: Self-diffraction appears when the strong laser goes through two-dimensional material suspension, and this spatial self-phase modulation (SPPM) phenomenon can be used to measure nonlinear optical parameters and achieve optical switch. At present, the mechanism of… read more here.

DOI: 10.1016/j.matlet.2017.11.130
Abstract: Abstract The third-order optical nonlinearities of Ag2Se nanocrystals were investigated by using Z-scan techniques. Large optical susceptibility χ(3) with the imaginary and real parts of 5.0 × 10−11 esu and −(3.0 ± 0.2) × 10−9 esu has been obtained under 1 mW laser excitation,… read more here.

DOI: 10.1128/mbio.01703-22
Abstract: Bacteria display a remarkable capacity to organize themselves in space and time within biofilms. Traditionally, the spatial organization of biofilms has been dissected vertically; however, biofilms can exhibit complex, temporally structured, two-dimensional radial patterns while… read more here.
