Tin sulfide (SnS), with a direct energy band-gap of about 1.3 eV, and a high optical absorption coefficient over 5 × 104 cm-1, is a promising new candidate for applications in the next generation of photovoltaic solar cells. Made of earth-abundant, relatively cheap and environmentally-nontoxic elements, SnS is solution processable and stable in both alkaline and acidic conditions.
Like the other family members of layered group IV monochalcogenides (including SnSe, GeS, and GeSe), 2D layered SnS has puckered structures - similar to those of black phosphorus. SnS crystallises in the form of an orthorhombic structure, where each Sn(II) atom is coordinated to six S atoms - with three short Sn–S bonds within the surface and three longer Sn-S bonds connecting outer surface of the same layer.
As an analogue to phosphorene, 2D SnS has also been predicted to have strong in-plane anisotropy. However, with two elements of different electronegativity (compared to phosphorene with its single element), the symmetry of SnS structure is rendered, leading to even richer physical properties.

就是蛋白质分子的小片断
是氨基酸形成的
求助各位前辈，我最近在合成的化合物水溶性很好，非常好，以至于可以随便溶解在水里，它的六氟磷酸盐也可以随意溶解在水里（大于50uM），细胞成像实验显示它根本进不去细胞，求问有没有啥方法包裹一下让它进去？我搜了一下文献，感觉多数是把脂溶性特别好的东西包裹一下弄进去的，也许是搜索姿势不对没找到我需要的答案，**点拨啊！！！
如题，之前没做过药代，老师给了一个600+Da的五肽，想测下药代动参数，看文献推荐上述两种方法，但是不知道选哪种更好，lcms前处理会不会影响小肽。
有机的是有机化合物的简称,它指的是含碳化合物.
但是,有四大类常见物质一般不作为有机物处理：
1、碳的氧化物,如CO和CO2.
2、碳酸及其盐,如CaCO3.
3、金属碳化物,如CaC2.
4、拟卤素及其化合物,如(CN)2与KSCN.
水的化学式为H2O,它不含有碳元素,故不是有机物.
但若所描述的水不是化学意义的水,而是自然界存在的天然水,那么,水中会溶有一定量的有机物.
