... Low TC-N; high TN-I larger T = TN-I - TC-N , higher the stability of the LC state In general, shorter the LC molecule, lower the phase transition temperature it has. For LC molecule contains more polarizable aromatic cores, or longer the body, Vander Waals interactions between LC molecules will inc ...

Hierarchically Porous Titania Networks with Controllable
... Titania has been extensively studied as a photocatalyst because of its chemical stability and nontoxicity. Recently many efforts have been made to improve its photocatalytic performance. Among them, forming anatase-rutile mixed-phase composites is an easy, low cost and scalable process, and is gener ...

The Analysis of Liquid Crystal Phases using Polarized Optical
... Thermotropic LCs are very sensitive to temperature. If the temperature is too high, thermal motion will destroy the ordering of LCs, and push it into a liquid phase. If the temperature is too low, thermal motion is hard to perform, so the material will become crystal phase. The existence of liquid c ...

Abstract
... The use of first row transition metals in catalysis as a substitute for scarce and expensive second and third row transition metals is still a challenge One strategy to promote the use of first row transition metals is the use of bimetallic complexes as the cooperativity between the metal centers mi ...
