When potato starch irradiated in ultra-violet light ... showed that the majority of the granules still retained their birefringence. If examined at room temperature, in water, iodine solution ...

THE birefringence of barium titanate has been measured over the range 4000–7000 A. Our attention was first directed to this work by the impossibility of obtaining the correct colour sequence in ...

Furthermore, researchers found that the birefringence of the three new compounds was negatively correlated with the Cl/Sb ratio, and the birefringence of Rb 2 Sb 2 OCl 6 reached 0.191 @550 nm ...

Using this method, the researchers synthesized a series of two-aminopyrazine-based birefringent crystals, four of which demonstrated exceptional birefringence values of 0.489, 0.490, 0.594, and 0. ...
