Nonlinear optics: A new borosilicate, Cs2B4SiO 9, has been synthesized (see picture). This compound represents a new kind of a boron-rich borosilicate and shows a 4.6 times stronger powder second-harmonic generation response relative to KH2PO4. In addition, Cs2B4SiO9 has a short UV cutoff edge (below 190 nm).
