Angular selective light transmission characteristics of a grating optical filter ** by Rustam Sabirovich Zakirullin

“…The relative position of two gratings provides angular selectivity of the light transmission. A graphic-analytical method is developed to determine the angular characteristic of the filter light transmission in the form of the dependence of the light transmission coefficient on the beams incidence angle. …”

In-depth insight into structure-reactivity/regioselectivity relationship of Lewis acid catalyzed cascade 4πe-cyclization/dicycloexpansion reaction by Ka Lu, Pan-Pan Zhou, Yong-Qiang Tu, Fu-Min Zhang, Xiao-Ming Zhang, Kai Li, Kun Fang, Yun-Peng Wang, Zi-Hao Li, Jia-Qi Li

“…Abstract The Lewis acid-catalyzed tittle reaction of 1,3-dicycloalkenlidine ketones is recognized as so far the shortest and most effective 1-step method for construction of angular tricyclic scaffolds, which are extensively found in bioactive terpenoids. …”
