“…The tourmaline-supergroup minerals with generalized structural formula [9] X [6] Y 3 [6] Z 6 ( [4] T 6 O 18 ) ( [3] BO 3 ) 3 V 3 W (Henry et al 2011) are widespread in nature (Grew et al 2017) and may form in various geological environments (e.g., Trumbull et al 2008;Arif et al 2010) under a wide range of thermodynamic conditions (London 2011;Setkova et al 2019). Tourmaline is widely used not only as a geochemical recorder (e.g., van Hinsberg and Schumacher 2007; Marschall and Jiang 2011) but also as promising material with piezoelectric (e.g., Li et al 2012) and pyroelectric properties (e.g., Chernyshova et al 2021), and ultraviolet optical nonlinearity (Xia and Kang 2022).…”

Me 4+ -bearing (Me 4+ = Sn, Ti) dravite analogs were synthesized in the system MeO 2 -MgO-Al 2 O 3 -B 2 O 3 -SiO 2 -NaO-H 2 O at 700 °C and 4 / 0.2 GPa in four hydrothermal experiments. Tourmalines form rosette-like aggregates and needle-like crystals that are chemically homogeneous. Tourmaline crystals obtained in high-pressure runs (4 GPa) are much smaller (up to 0.1 × 2 μm) and have lower Me 4+ (0.27 wt. % SnO 2 , 0.57 wt. % TiO 2 ) than those from the low-pressure (0.2 GPa) runs (up to 1 × 5 μm; 1.77 wt. % SnO 2 , 2.25 wt. % TiO 2 ). Synthetic analogs of rutile, quartz and coesite were obtained in the system TiO 2 -MgO-Al 2 O 3 -B 2 O 3 -SiO 2 -NaO-H 2 O, whereas synthetic analogs of cassiterite, tin-rich (up to ~19.55 wt. % SnO 2 ) Na-pyroxene, MgSn(BO 3 ) 2 (Mg-analogue of tusionite), quartz and coesite were synthesized in the system SnO 2 -MgO-Al 2 O 3 -B 2 O 3 -SiO 2 -NaO-H 2 O. We suggest that at a high temperature (≥ 700 ºC), the pressure negatively affects the Ti incorporation into the tourmaline structure. In contrast, at relatively low pressures, the Ti incorporation in tourmaline structures is governed by the Ti content in the mineral-forming medium. Low-pressure conditions are feasible for Sn incorporation in the tourmaline structure. The presence of Ti 4+ and Sn 4+ cations in structures of the synthesized tourmalines (probably at octahedrally coordinated sites), is also indicated by changes in the unit-cell parameters.

“…The pH of M‐1, M‐2, M‐3, and M‐4 membranes all increased under 0.2 MPa loading pressure compared to that without loading pressure, with the pH of filtered M‐4 membrane increasing to 6.96. The spontaneous polarization effect of tourmaline is manifested not only as a thermoelectric effect, but also as a piezoelectric effect, 49 and when mechanical stress is applied to the surface of tourmaline, its surface will generate an electrical charge that will increase its effect of regulating pH regulation.…”

In order to reduce the agglomeration of tourmaline, silane coupling agent (3‐aminopropyl)‐triethoxysilane (KH‐550) was used to modify tourmaline. Then the modified tourmaline particles were added to the polyvinylidene fluoride (PVDF) casting solution by blending, and a series of PVDF/TMKH‐550 composite membranes were prepared by Nonsolvent Induce Phase Separation (NIPS). The results showed that the agglomeration of tourmaline could be reduced by modification. With the increase of TMKH‐550 nanoparticles content, the removal efficiency of ammonia nitrogen wastewater increased gradually. For PVDF/TMKH‐550 composite membranes, the results showed that the addition of TMKH‐550 nanoparticles improved the hydrophilicity, porosity, and pore size of the membrane, and increased the permeation flux. The removal efficiency of the composite membrane on ammonia nitrogen solutions could reach 75.40%, The pH and conductivity of deionized water after membrane filtration were tested. At 0.2 MPa, it was found that both pH and conductivity increased. The above results showed that tourmaline can not only activate water bodies but also remove pollutants in water.

The cause of the primary distortion in both d 0 transition and SALP cations can be ascribed to the second-order Jahn–Teller (SOJT) effect.…”

A noncentrosymmetric nonlinear optical (NLO) crystal Cd3Te2WO10 with a large band gap has been synthesized and grown using the high-temperature solution method with TeO2 as a flux. Cd3Te2WO10, crystallized in P21, contains two classes of d0 W6+ and lone-pair Te4+ cations holding asymmetric coordination environments which are associated with the second-order Jahn–Teller effect. Importantly, it has a large band gap of 4.28 eV, which is profitable for high-power application, and wide transparency region of 0.29–5.63 μm, especially in 1–5 μm possessing tremendous transmittance that exceeded 80% and fully covering the 3–5 μm range, which is one of the vital atmospheric windows, and a good Raman performance that arises from the WO4 polyhedra. In addition, Cd3Te2WO10 features phase-matching behavior owing to large birefringence and considerable second-harmonic generation response equivalent to 1.1 times that of KH2PO4, which is further elucidated by the theoretical calculation. Therefore, our experimental results demonstrate that Cd3Te2WO10 could be used as a promising functional NLO crystal.
