Free radicals affect each of these in similar ways. For example, nasal mucus is a response to bacterial infection in humans and the green colour is largely associated with the enzyme myeloperoxidase. The principal func-tion of this enzyme is to create bleach in vivo through a free radical cascade with the ultimate aim of killing bacteria. In another example, damage to cultur-ally significant objects such as outdoor monuments and frescos can be caused by the growth of biofilms and the subsequent production of harmful metabo-lites. In model organisms such as Pseudomonas aeruginosa, these events have been found to be linked with oxidative and nitrosative stress, and free radi-cals, in particular nitric oxide. This presentation will discuss the connection between free radicals and their impact in areas that range from art through to medicine. Through a sound knowledge of the chemistry of biology is is possible to design molecules that take advantage of free radicals in order to improve health outcomes as well and provide improved conservation options for important cultural heritage.<br \/><br \/><\/p>\n<p style=\"font-weight: 400\">\u00a0<\/p>\n<h3 style=\"font-weight: 600\"><b><strong>New Synthetic Routes toward Robust and Functionalized Metal-Organic Frameworks<\/strong><\/b><\/h3>\n<p style=\"font-weight: 400\">Prof. Dr. Hong-Cai Zhou<br \/><em>Professor,\u00a0<\/em><em>Department of Chemistry, Texas A&amp;M University, College Station, Texas<\/em><br \/>\u00a0\u00a0<\/p>\n<p style=\"font-weight: 400\">Local: Anfiteatro C<br \/>Data: segunda-feira, 18 de agosto de 2014<br \/>Horas: 14h30<\/p>\n<p style=\"font-weight: 400\"><b><strong>Resumo:<\/strong><\/b><\/p>\n<p style=\"font-weight: 400\">\u00a0<\/p>\n<p style=\"font-weight: 400\">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<p style=\"font-weight: 400\">References:<\/p>\n<ol>\n<li style=\"font-weight: 400\">Liu, T.-F.; Zou, L.; Feng, D.; Chen, Y.-P.; Fordham, S.; Wang, X.; Liu, Y.; Zhou, H.-C., J.
