IMRE seminar on "Metal Carbenes in Unusual Environments"
4 Aug 15 (Tue) - 02.30pm - 03.30pm
More than 50 years ago, E. O. Fischer in Munich reported the first stable metal carbene complex. More recently, N-heterocyclic carbenes have been established as a versatile ligand family in many synthetic and catalytic applications. Three new systems will be discussed which illustrate the remarkable utility of heterocyclic carbenes in organometallic chemistry.

IMRE seminar on "Chirality of Supramolecular Aggregates from Achiral Building Blocks"
4 Aug 15 (Tue) - 04.00pm - 05.00pm
The observation of induced CD signals from the chromophore that is built in the achiral building block can indicate the formation of helical aggregates, when a chiral species that interacts with the building block molecule. The induced CD signals could characterize the chirality of the formed supramolecular aggregates, which will be discussed in examples of perylenediimide derivatives being the building blocks.

IMRE seminar on "Protein Structures, Basic Science and My Experiences with Application in Medicine"
6 Aug 15 (Thu) - 10.00am - 11.00am
Structural biology was successful, because it was recognized that understanding biological phenomena at the molecular and atomic level requires seeing molecules. It reveals the structure of genes and their basic mechanism of regulation, the mechanism of enzymes’ function, the structural basis of immune diversity, the mechanisms of energy production in cells by photosynthesis and its conversion into energy- rich chemical compounds and organic material, the mechanism that makes muscle work, the architecture of viruses and multi-enzyme complexes, and many more. My seminar will start out with the history of protein crystallographyand note major factors contributing to its development. Few examples shall illustrate how structure information contributes to our understanding of the physical and chemical basis of biological phenomena and may lead to medical application. I will also let you share my experience with the foundation and developments of two biotech companies (Suppremol and Proteros) with different business models, but both based on basic academic research in structural biology.

IMRE seminar on "Predictive Design of Multifunctional Solid Catalysts"
6 Aug 15 (Thu) - 02.30pm - 03.30pm
The ability to devise and design multifunctional active sites at the nanoscale, by drawing on the intricate ability of enzymes to evolve single-sites with distinctive catalytic function, has prompted complimentary and concordant developments in the field of catalyst design and in situ operando spectroscopy. The choice and proximity of these multifunctional sites coupled with their propensity to modify and tailor the local-structural environment in their immediate vicinity has since instigated the predictive design of novel heterogeneous solids for targeted catalysis. These characterization tools have facilitated robust structure-property correlations to be established, which have enabled the rational design of highly active and selective catalysts for selective oxidation and acid-catalysed processes. The talk will focus on strategies for the integration and amalgamation of these developments leading to the discovery and design of novel microporous and hierarchical architectures for sustainable catalytic transformations.

IMRE seminar on "Diverse Metal-Organic Frameworks from A Single Crystal"
11 Aug 15 (Tue) - 10.00am - 11.00am
In this talk, I shall elaborate our recent progress in building metal-organic frameworks from a two-dimensional coordination polymer single crystal.

IMRE seminar on "Parent Amido and Imido Complexes: From Ammonia Activation to Cluster Chemistry"
11 Aug 15 (Tue) - 02.30pm - 03.30pm
Parent amido-bridged complexes tetrafluorobenzo-barrelene or cyclooctadiene can be prepared by treatment of the methoxo-bridged compounds with gaseous ammonia.These compounds are interesting platforms of unusual low-valent metal amido complexes to explore their reactivity.

IMRE seminar on "Copper Reagent for the Synthesis of Organofluorine Compounds"
12 Aug 15 (Wed) - 10.00am - 11.00am
Organic fluorine-containing compounds have important applications in the pharmaceutical, agricultural and advanced materials industries. These organocopper reagents exhibit good reactivity and regiospecificity for the incorporation of fluorine-containing groups into organic molecules.We report our studies of the synthesis, structures, and reactions of new copper(I) compounds containing fluorinated groups. A series of dinitrogen-ligated, fluorine-containing copper complexes have been synthesized and structurally characterized. These well-defined complexes react with a wide range of organic halides to produce the corresponding organic fluorine-containing compounds in good to excellent yields.

IMRE seminar on "Auro, Argento and Mercurophilic Interactions in Molecules and Crystals"
13 Aug 15 (Thu) - 02.30pm - 03.30pm
A quarter of a century of research has demonstrated that metallophilic interactions between the seemingly closed-shell gold(I), silver(I) and mercury(II) centers are ubiquitous in molecules and materials and have a marked influence on the structure and properties of the systems. And yet, the impact of the effect varies very strongly with the nature of the metal center and of its ligands. Interaction energies may reach values near or beyond that of hydrogen bonds, or are so weak that they can hardly be distinguished from those associated with standard dispersion forces. Recent results will be presented to illustrate the scope of the interactions.

IMRE seminar on "Development of Biosensors for Medical and Environmental Applications"
18 Aug 15 (Tue) - 02.00pm - 03.00pm
This seminar will present the development of various technologies developed in our laboratory over the years, which are mostly multi-disciplinary in scope (chemistry, molecular biology, physics, data mining and chemical engineering). Most have been validated using real-life samples from various continents.The biosensors are divided in two categories, one based on affinity bioreceptors and the other on live cells. Some of the devices are meant for point-of-care, on-site or flow-through sensing. These include chemiluminescence-based fiber-optic immunosensors to viral pathogens (Ebola, Dengue, Hepaptitis C, West Nile virus, Rift Valley fever, CCHF) – the BioPen concept; biochip immunosensors based on electrogenerated films deposited on ITO chip surfaces; magnetic liquid fiber guide immunosensors; diagnostic phagocytic chemiluminescent imprints to identify clinical ailments or other techniques still in development such as the detection of negative stranded RNA viruses (influenza) using reverse genetics cell sensors. Work on nanostructures for enhanced immunosensors or metal enhanced bioluminescence will also be discussed.
