不饱和醇是一类重要的医药中间体,然而C=C加氢比C=O加氢反应更具有热力学优势,因此由不饱和醛合成不饱和醇具有挑战性.为解决这一问题,需要寻求一种具有可调控选择性的氢化催化剂.二维沸石的高长径比和大量的末端基团作为锚定位点,使其不仅能作为催化剂载体,还可以有效地调节催化剂性能.本研究利用二维沸石IPC-1P作为铂纳米颗粒的载体,成功制备出异相催化剂Pt@IPC-1P.铂纳米颗粒的尺寸小于2 nm且均匀地分布在IPC-1P上.令人惊喜的是,Pt@IPC-1P催化剂对不饱和醇的选择性超过了90%,并实现了接近100%的催化转化率,远超其他铂基催化剂.理论计算证实,二维沸石IPC-1P在肉桂醛向肉桂醇的转化过程中起到了积极作用,其放热效应能量高于苯丙醛.这项工作展现了二维沸石在催化有机物转化领域具有广阔的应用前景.

In this paper, antibody-modified silica nanoparticles were successfully synthesized, and their average di- ameter was （1094-9） nm. These particles were mixed with cell extracts to target a protein, then, an antibody labeled with fluorescein isothiocyanate（FITC） was added to form FITC-labeled nanoparticle complexes and the product was analyzed using flow cytometry. The results confirm that the intracellular proteins and biomarkers were precisely and sensitivity detected by the novel method in vitro. The FITC intensity of Akt antibody-conjugated particles was in- creased ≥ 10-fold compared with that of control samples in MCF-7 cells. Furthermore, it can also simultaneously measure several proteins when modified with different antibodies.

Eggshells are one of the most common and well-studied biomaterials in nature and exhibit unique properties of gas conduction. However, the morphologies of eggshells at the submicro-/nano-scale and their impact on eggshell functions remain unclear. In this work, the architecture of hen＇s eggshell at different length scales has been systematically investigated by scanning electron microscopy （SEM） and environmental SEM （ESEM）. It is found that the skeleton of calcium carbonate （CaCO3） has hierarchical structures at nano- to micro-scales： primary nano-particles of -10 Fain loosely congregate giving a porous and rough texture, and compose the upper-level morphologies including submicro spheres, nano-rods, rhombohedral-cleavage pattern and slices, which are elaborately arranged in a surface layer, palisade layer and mammillary layer along the radial direction. Accordingly, the pore system exhibits a three-level hierarchy, namely nano-scale pores （between nano-rods and primary nano-particles）, submicro-scale pores （＂bubble pores＂） and micro-scale pores （opening of ＂gas pores＂）. Further investigation shows that hen＇s eggshell regulates gas conduction through adjusting the sizes and numbers of submicro-scale ＂bubble pores＂. Based on our observations, a new description of hen＇s eggshell is presented, which amends the conventional view of micro-scale, straight and permeating ＂gas pores＂, and reveals the role of hierarchical pores in gas conduction and contamination resistance.
