Lithium Niobate ( LiNbO3) is notable by a favourable balance of electro-optic, acoustic, piezoelectric, pyroelectric and non-linear optical attributes and is therefore the best material for applications in electro-optical, non-linear optical, and acoustic devices, high-temperature acoustic transducers, receivers-transmitters of acoustic vibrations, air force acceleration meters, acoustic wave delay lines, deflectors, generators of non-linear distorted waves, acoustic filters, electro-optical modulators (Q-switches), converters, frequency doublers and resonators in laser systems, non-linear elements in parametric light generators, and many others. The listed devices can be found anywhere from consumer electronics (TV sets and cell phones) and medical instruments (surgical and therapeutical appliances) to advanced laboratory and scientific equipment (biotechnology, frequency standards, metal cutting, shaping, scribing).LiNbO3 blanks and substrates for SAW and transducer applicationsDiameter5-76.2 mmThickness/=0.15 mmOrientationYX 36, YX 42, YX 49, YX 64, YX 128, YX 136, YZ, Z, X, YMaterial quality For Acoustoelectronics or Optoelectronics applicationsSurface qualityAs-cut, fine-ground, lapped, 20/10 polishedPlease check our Optics stock.

The only commercially available TlInS2 vdW crystals have been synthesized at our facilities through float zone technique. TlInS2 semiconductors belong to the thallium chalcogenides family with the chemical formula TlBX2 (where B=In or Ga, X=S, Se or Te). Members of this family have both layered (TlGaSe2, TlGaS2, TlInS2) and chain (TlInSe2, TlInTe2, TlGaTe2) structures. Stacking of the atoms in TlGaSe2, TlGaS2 and TlInS2 layered crystals is arranged in the form of two twisted anionic layers with the weak bonded Tl(+1) cations located in the trigonal cavities between them. As a result, these crystals exhibit layered structure with weak vdW coupling between the adjacent layers. In particular, TlInS2 is a direct gap semiconductor with optical band gap of 3.5 eV, it exhibits rather novel ferroelectric, ferroelastic behavior. Owing to its crystal structure it is also known to be second harmonic generation (SHG) semiconductor.Properties of TlInS2 crystals

YMC-光学异构体和结构异构体分离柱 在商业上有价值的环型多聚糖环糊精，由三种成分组成，包括：α-环糊精(六环)、β-环糊精(七环)和γ-环糊精(八环)，如下图所示。这种圆锥状环糊精分子具有一个疏水的空穴和一个碳水化合物上的亲水边缘。在残存的葡萄糖上碳原子6上的一级羟基具有较小直径的边缘，葡萄糖上的2和3碳原子上的二级羟基则形成较大直径的边缘。空穴的直径如同一个单独的苯环，或取代基单个的苯环和多环系统的变化。 YMC Chiral CD BR液相色谱柱提供了对镜像异构体分离的一个选择方法。环糊精上的溴代衍生物共价键合到YMC硅胶上形成一个新的手性固定相(CSP，Chiral Stationary Phases)。在溴代衍生物中第六个碳原子上的羟基被溴化物取代，从而提供了不同于环糊精的手性异构选择性。 这种环糊精溴化衍生物被用于反相模式的液相色谱分离，其具有广范围的分离特性，适合于极性和水溶性化合物的分离，此外，其在相似的条件下也可用于分离芳香族化合物取代基的位置异构体分离。 YMC Chiral CD BR色谱柱可在pH 3.5-6.5范围和通常使用的缓冲液色谱系统中使用。但是在保存该种色谱柱时，必须用水/甲醇溶液(80-100%水)将分析后柱内残留的盐分和缓冲液全部冲洗干净，色谱柱必须储存在无盐的水/甲醇(50%甲醇)的条件下。如果可能可用三氟醋酸(THF)清洗除去残留，以再生色谱柱。 Chiral CD BR系列液相色谱柱的特点 环糊精结构的光学异构体分离柱，有α-、β-和γ-三种类型的柱填料 反相-液相色谱柱；粒径：5µ m；孔径：12nm (120Å )；适用pH范围：3.5-6.5 用于光学异构体和结构异构体化合物的分析 用于反相、极性和水溶性药物或化合物的位置异构体分离
