Be₂BO₃F: A Phase of Beryllium Fluoride Borate Derived from KBe₂BO₃F₂ with Short UV Absorption Edge

A phase of beryllium fluoride borate Be₂BO₃F (BBF) was successfully developed and grown by spontaneous nucleation from high temperature solution. The crystal belongs to the trigonal space group of <i>R</i>3̅<i>c</i> (No. 167), with lattice parameters <i>a</i> = 4.442(1) Å, <i>c</i> = 24.956(5) Å, and <i>Z</i> = 2. It is constructed by the infinite planar [Be₂BO₃F₂]_∞ layers, in which the planar triangle [BO₃]^3– and the tetrahedral [BeO₃F]^5– anionic groups are arranged in parallel via corner-sharing O atoms in each <i>ab</i> plane. BBF is an incongruent compound and decomposes at about 650 °C. The deep-ultraviolet (DUV) transmittance spectrum reveals that its UV cutoff wavelength is down to ∼150 nm. Theoretical calculations show that BBF has a large birefringence (Δ<i>n</i> = 0.13 at 200 nm), which mainly originates from the infinite planar [Be₂BO₃F₂]_∞ layers. In conclusion, BBF may be served as a potential DUV birefringent material

Two KBBF-Type Beryllium Borates MBe₂B₂O₆ (M = Sr, Ba) with a Three-Dimensional (Be₂B₂O₆)_∞ Network

Two new polyborates, BaBe₂B₂O₆ and SrBe₂B₂O₆, in a three-dimensional (Be₂B₂O₆)_∞ network featuring KBBF-type two-dimensional planes are synthesized. Compared with KBBF, both compounds possess comparable optical birefringence and deep-ultraviolet (deep-UV) cutoff edges and exhibit better bulk growth habits owing to their three-dimensional networks, which make them applicable deep-UV optical materials

EMT inhibition potentiates the spasmolytic action of isoprenaline.

<p><i>A</i>, famotidine, a potent EMT inhibitor, when added in the replacement of cortisol, achieved a more profound permissive effect for isoprenaline (n=3 in each group), * <i>p</i><0.05 <i>vs</i>. control. <i>B</i>, there was no additive effect when famotidine and cortisol were administrated in sequential order. <i>C</i>, with famotidine preincubation, cortisol did not further potentiate the spasmolytic action of isoprenaline. <b><i>D</i></b>, a similar contractile response was produced by histamine with or without famotidine pretreatment. <i>E</i>, SPG method to quantify catecholamine uptake by tracheal chondrocyte. Pretreatment with EMT inhibitors (cortisol or famotidine) hampered catecholamine uptake (50 μM norepinephrine, 20 min incubation). Fluorescent intensity was measured in approximately 50 cells for each group, * <i>p</i><0.05, ** <i>p</i><0.001 <i>vs</i>. control. a.u., arbitrary unit.</p
