DOI: 10.1016/j.optlastec.2017.05.009
Abstract: Abstract The excellent propagation properties of square-lattice microstructured optical fibers (MOFs) have been widely recognized. We generalized our recently developed analytical field model (Sharma and Sharma, 2016), for index-guiding MOFs with square-lattice of circular air-holes… read more here.

DOI: 10.1039/d1cc06638b
Abstract: We report that the previously reported square lattice coordination network [Ni(4,4'-bipyridine)2(NCS)2]n, sql-1-Ni-NCS, undergoes acetylene induced switching between closed (nonporous) and open (porous) phases. The resulting stepped sorption isotherms exhibit temperature controlled steps, consistent high uptake… read more here.

Abstract: Switching coordination networks (CNs) featuring stepped sorption isotherms that are accompanied by phase changes offer promise for gas storage and separation applications. However, their responsiveness to different adsorbates remains largely understudied. Herein, we report the… read more here.
