Dominique Massiot “Order and disorder at the nanoscale geometry, chemistry, topology”

September 18 @ 4:30 pm

Dominique    Massiot CEMHTI,    UPR3079    Orléans http://www.cemhti.cnrs-orleans.fr/ Controlling    the    chemistry    and    the    structure    of    materials    is    a    key    to    understanding,    tuning,    and    enhancing    their    properties.    However,    detailed    structural    and    chemical    characterization    of    materials    in    three    dimensions,    whether    homogeneous    or    heterogeneous,    remains    challenging    at    the    atomic    and    nanometer    length    scales.    We    have    developed    a    panel    of    methods    and    approaches    that    combine    new    experimental    solid-state    NMR    methods    and    DFT-based    in    silico    modelling,    which    jointly    enable    characterization    of    chemical    and    geometrical    order,    as    well  …

Francesco Stellacci “Supramolecular approaches to Engineer Materials Interactions with Viruses: From Stabilization to Virucidal Drugs”

September 25 @ 11:00 am
ISIS,

Francesco Stellacci Institute of Materials, and Interfaculty Bioengineering Institute, Ecole Polytecnique Fédérale de Lausanne (EPFL), Lausanne, 1015, Switzerland Email: francesco.stellacci@epfl.ch Viruses kill every day in large numbers especially in low-income countries. Any given day ~1600 children age 1 to 5 die of diarrhea (mostly due to rotavirus). More than 5000 people have died of Ebola in the last outbreak. On the other hand, viruses also save lives as vaccines; unfortunately, because of their thermal instability, vaccines need constant refrigeration. This…

Prof. Dr. Thorsten Stafforst “Site-specific Manipulation of Nucleic Acids with (Bio)Chemical Tools”

October 9 @ 4:30 pm
ISIS,

Prof. Dr. Thorsten Stafforst Interfaculty Institute of Biochemistry, Auf der Morgenstelle 15, 72076 Tübingen (Germany) thorsten.stafforst@uni-tuebingen.de www.ifib.uni-tuebingen.de/research/stafforst/   RNA modifications shape the expression of genetic information in many ways. Tools to manipulate single nucleobases at specific sites in selected transcripts in vivo are rare. We are engineering artifical RNA-guided proteins that allow to perform site-directed RNA editing in a highly rational and specific way (1-5). We will present new data that demonstrate highly specific and parallel editing of several endogenous…

Pr Thorsten Bach “Chirality and Light: Enantioselective Catalysis of Photochemical Reactions”

November 20 @ 4:30 pm
ISIS,

Pr Thorsten Bach Technische Universität München Chirality and Light: Enantioselective Catalysis of Photochemical Reactions   Photocycloaddition reactions belong undisputedly to the most important reaction classes in photochemistry. The creation of up to four new stereogenic centers in a single step and the further use of the formed cyclobutane rings – either directly or after appropriate ring opening – are hallmarks of this powerful transformation. In our group, we have studied two different approaches to achieve a catalytic enantioselective reaction…
