Abstract
Rational chemical substitution is an effective way to regulate structure and enrich property. Herein, a new noncentrosymmetric borosilicate, Ba2ScBSi2O9, was successfully synthesized by substituting CaO6 units in Ba2CaB2Si4O14 with ScO6 octahedra, with comparatively strong covalency. This substitution not only effectively prevents polymerization of the B-O groups, resulting in an intriguing structural transformation from tetrahedral-coordinated borosilicate of Ba2CaB2Si4O14 to mixed-coordinated borosilicate Ba2ScBSi2O9, but also enhances its second harmonic generation response (2 × KDP), that is nearly four times higher than its parent structure while keeping a short ultraviolet (UV) cutoff edge (λcutoff < 190 nm). In addition, the polar space group of Pca21 for Ba2ScBSi2O9 achieves its ferroelectric polarization reversal capability, which makes quasi-phase-matching technology possible to counteract the nonphase-matching caused by small birefringence of silicates. This work indicates the unique role of heterovalent substitution in regulating structure and performance, providing new insights for exploring borosilicate with versatile functionality.

Abstract
Two apatite-related silicates compounds, Tb2Pb3Si3O12 (I) and Pb5SiP2O12 (II), were obtained in the crystalline forms. Structure and ELF calculated results reveal that the lone pair cation of Pb2+ preferentially occupies the Cs site, and the repulsion between the mutual lone pair stabilizes channels. Moreover, combining conductivity results this preference has the important implications of exclusion and blocking the movement of the oxide ion in the channel of apatite-related structures. Our findings provide an experimental foundation for further interpreting the conductivity decrease in lone-pair ions as dopants into apatite-related silicate materials.

Abstract
We report on the growth of single crystals of an electron-doped titanium oxyfluoride, Li2Ti(O,F)3, employing high-temperature electrolysis of TiO2 with a eutectic Li2MoO4-LiF melt. Greenish octahedral-shaped crystals (∼30 μm in size) with a cubic rocksalt-type structure were successfully obtained by precisely tuning the applied voltage. The temperature-dependent magnetic susceptibility data revealed a paramagnetic behavior at low temperatures, ensuring the presence of Ti3+ ions (mean valence number of +3.78; F/Ti ∼ 0.15). The crystals exhibited clear visible-light absorption and produced H2 from water in the presence of a sacrificial reagent under UV-light irradiation. Li2Ti(O,F)3 more efficiently produced H2 compared with a nondoped oxyfluoride Li5Ti2O6F, likely due to the doped electrons for the former. This work highlights a promising electrochemical approach toward growing electron-doped oxyfluoride crystals.

Abstract
The birefringence of BaTi(BO3)2 is equal to or larger than 0.169 at 546 nm (Δn(cal.) = 0.185 at 546 nm), which mainly originates from the high-density and parallel arrangement of the isolated [BO3] triangles in the unit cell.
