Novel approaches, such as the use of tandem mass spectrometry (ICP-MS\/MS), provide even more powerful means to overcome spectral interferences and thus, enable straightforward determination of elements that previously were hardly accessible, such as Ti in blood serum, measured to detect wear of prostheses in an early phase. New guidelines concerning elemental impurity limit concentrations in pharmaceutical substances are currently being adopted by the United States Pharmacopeia (USP), such that ICP-MS is also gaining ground in the pharmaceutical industry.<\/p>\n \u00a0<\/p>\n New Synthetic Routes toward Robust and Functionalized Metal-Organic Frameworks<\/h3>\nProf. Dr. Hong-Cai Zhou Local: Anfiteatro C Resumo:<\/p>\n The field of metal-organic frameworks (MOFs, or porous coordination polymers, a. k. a. PCPs) is built upon three pillars: cluster chemistry, organic synthesis, and X-ray crystallography. Robust MOFs with high porosity are needed for applications such as gas storage, separation, and catalysis. In the late 1990s, MOFs with high porosity were commonly made from commercially available ligands such as benzene dicarboxylate (bdc) and benzene tricarboxylate (btc) in a one-pot solvothermal reaction. Though straightforward, the scope of this synthetic method is limited and MOFs with desirable porosity, stability, and functionality for applications are difficult to obtain. Our research is focused on the discovery of new synthetic methods to access MOFs that can perform unique chemical transformations and exhibit desired properties for clean-energy-related applications. Under this main theme, strategies such as construction of MOFs with desired porosity and functionality through ligand design, building MOFs one cavity at a time, metal-ligand-fragment co-assembly, MOF surface engineering, framework as a template for MOF preparation, post-synthetic metathesis and oxidation (Fig. 1),1 and the preparation of MOFs through symmetry-guided design,2 have been developed. In the presentation, I will focus on the most recently developed MOF synthetic methods in our laboratory, especially those related to the three pillars of MOFs.<\/p>\n References:<\/p>\n 1.
