Multidisciplinary Seminar

TITLE:  Gradient and uneven nano-patterns distributions for cell adhesion and differentiation studies
SPEAKER:  Josep Samitier (Institute for Bioengineering of Catalonia)

WHEN: 25/10/2013, 12:00
WHERE: Sala de Graus, ETSEQ

ABSTRACT: Cell adhesion onto bioengineered surfaces is affected by a number of variables, including the former substrate derivatisation process. Cells can sense and respond to their immediate surroundings. The information arising from this environmental sensing is integrated into the cell machinery through receptor proteins located at the cell membrane. We have studied the correlation between cell adhesion and cell–adhesive ligand surface gradient concentration. Similar procedure has been used to systematic in vitro screening of the effects of different concentrations of immobilized Bone Morphogenetic Protein (BMP-2). For this purpose, gradient surfaces were created on poly(methyl methacrylate) substrates by continuous hydrolysis and were then grafted with biotin-PEG-RGD molecules or BMP-2 molecules. In addition, nano-patterning of arginine-glycine-aspartic acid (RGD)-tailored dendrimers has been used to obtain uneven distributions of cell-adhesive motives. Cell adhesion studies reveal that first adhesion events are dictated by the surface layout and reinforced by a narrow interligand spacing and high local ligand densities.. This is a simple, all-organic nano-patterning approach that can be easily scaled up to large surface areas. The biocompatible and biodegradable nature of dendrimers also opens for biomaterial applications.

Multidisciplinary Seminar

TITLE:  Microchip technology in drug metabolism research and mass spectrometry-based bioanalysis
SPEAKER:  Tiina Sikanen (Division of Pharmaceutical Chemistry, University of Helsinki, Finland)

WHEN: 18/10/2013, 12:00
WHERE: Aula 104, ETSEQ

ABSTRACT: The main influential aim in our research is to develop inexpensive, high-throughput technology for screening of the thus far less explored (molecular level) metabolic interactions between environmental or household chemicals and clinically relevant drugs. The focus is primarily on human phase I metabolism (redox reactions) of common toxicants like agrochemicals, detergents and plasticizers. On the basis of their structural resemblance to pharmaceuticals, many of these chemicals are suspected to have critical effects on cytochrome P450 metabolism which is the main detoxification route of exogenous compounds (like pharmaceuticals) as well as many drug-like endogenous compounds (like hormones) in man. However, the maximum throughputs of the current state-of-the-art analytical techniques are of the order of one-two sample(s) per hour so that screening of such large chemicals pool would take unreasonably long time. In fact, new chemicals are introduced faster than the existing compounds are screened.
Our main (technological) goal is to develop novel, practically zero-cost analytical instruments that enable characterization of a compound’s metabolic profile at very high speed (<1 min per sample). This goal is achieved through miniaturization and comprehensive integration of several analytical unit operations by microfabrication means – an approach of which is often referred to as lab(oratory)-on-a-chip or Micro Total Analysis Systems (µTAS). These microfabricated arrays are envisioned to incorporate all analytical key functions from (enzyme) reactions and sample pretreatment to separation and detection of the reaction products (metabolites) on a single microfluidic platform. Thanks to the decrease in dimensions, the amount of chemical waste and consumption of expensive reagents are significantly reduced. A key element is to explore new microfabrication techniques, from delicate cleanroom processes to extremely simple printing techniques, and their exploitation to production of smart microfluidic designs and multifunctional surfaces. Numerical modeling of fluid dynamics and various transport processes is also an integral part of the microdevice development. From the biological point-of-view, the microchip technology is able to provide improved technological solutions for studying of, for instance, very rapid (~msec) enzyme-catalyzed reactions and the reaction mechanisms thereof. Here, the microchip technology proves superior to any conventional technique, since it allows truly zero-dead-volume (i.e., no time lag) mixing even in microchannels with multiple interconnections. With conventional instruments, such studies are hardly possible or, at the very least, severely compromised because of their poor control over (reaction) time resolution. At best, identification of pre-steady state (sub-msec) reaction intermediates by mass spectrometry should be achieved. This in turn gives us new perspective into determination of the route of potentially hazardous, unexplored metabolic interactions of environmental and household chemicals with clinically relevant drugs.

TITLE: Applications of engineered metal nanoparticles for the treatment of allergicdiseases by immunotherapy and for bioimaging
SPEAKER:  Xavier Le Guevel (The Andalusian Centre for Nanomedicine andBiotechnology, BIONAND)

WHEN: 11/10/2013, 12:00
WHERE: Sala de Graus, ETSEQ

ABSTRACT: Nanotechnology and particularly nanoparticles (NPs) have receivedmuch attention over the last 10 years in the field of immunotherapy. One of themost successful strategies of using NPs for specific immunotherapy is based ontargeting dendritic cells (DCs), which play a central role on the activation ofthe immune system. Engineered nanoparticles can specifically be designed toeither target or avoid interactions with the immune system leading to an immunestimulation or and immunosuppression responses. However, the understandingthrough systematic study on the exact effect of size, shape or surface chargeof NPs to the interaction and the immune response of DCs remains unclear. Weaim to assess the effect of gold NPs with different physico-chemical parametersto the immunological response of DCs.

Noble metalnanoclusters (NCs) have gained a tremendous interest in the field ofnanomedicine for biosensing and bioimaging due to their small size, highphotostability, luminescence properties, biocompatibility and high sensitivityto their environment. Few-atom nanoclusters differ from gold or silvernanoparticles in that they can be highly fluorescent, do not support a surfaceplasmon, and do not have the metallic and bulk-like properties of nanoparticles/nanocomposites.NCs are usually stabilized in solution by thiols ligands or templates whichacts as cavities such as polymers, DNA, peptides or proteins. We will highlightthe recent advances on the synthetic routes to produce highly luminescent andstable NCs and their respective performance in in vitro and in vivo studies.

TITLE:  Computers, life and synthetic life: redesigning evolution?
SPEAKER:  Ricard Solé (ICREA-Complex Systems Lab UPF-IBE)

WHEN: 04/10/2013, 12:00
WHERE: Sala de Graus, ETSEQ

ABSTRACT: Computation is an attribute of all forms of life. Every single living entity performs, at different scales, information processing involving both the external environment and the internal state. What defines life is actually deeply tied with the existence of such computational processes taking place within living networks of interacting elements. To a large extent, evolution has been shaping computational levels on multiple scales and we can see that ants, cells and brains are capable of different levels of information processing and decision making. At the cell and tissue levels, the observed forms of computation remind us Turing machines or standard electronic systems. Are there other forms of computation beyond the standard engineering metaphors? Synthetic biology offers a unique possibility of exploring this question and even designing forms of computation that do not exist in nature. Here we consider the potential landscape of biocomputations and what might be beyond it.

TITLE: Buoyancy driven flows: research and applications
SPEAKER: Chengwang Lei (School of Civil Engineering, The University of Sydney, Australia)

WHEN: 27/6/2013, 12:00
WHERE: Aula 117, ETSEQ

ABSTRACT: Buoyancy occurs whenever there is a density variation under the effect of a body force. A flow will result from the buoyancy acting within a fluid medium, which is referred to as buoyancy driven flow. This type of flow exists extensively in nature and in domestic and industrial processes. An overview of the applications of buoyancy driven flows will be presented. This will be followed by an introduction of analytical and experimental methodologies adopted in the research of buoyancy driven flows. Finally, some research projects on buoyancy driven flows including thermally driven exchange and transport in natural water bodies, enhancement of heat transfer by natural convection, and solar induced natural ventilation in buildings will be highlighted.

Multidisciplinary Seminar

ITLE: Molecular Modeling in Heterogeneous Catalysis: the Methanol-to-Olefins Process as a Case Study
SPEAKER:  Karen Hemelsoet (Center for Molecular Modeling, University of Gent, Belgium)

WHEN: 14/06/2013, 12:00
WHERE: Aula 118, ETSEQ

ABSTRACT: This lecture will focus on the conversion of methanol to olefins (MTO) over a heterogeneous nanoporous catalyst material. In particular, I will demonstrate how molecular modeling can provide detailed molecular-scale insight.[1]

The MTO process is a highly complex process involving a cascade of elementary reactions.[2] The elucidation of the reaction mechanisms leading to either the desired production of ethene and/or propene or the undesired deactivation has challenged researchers for many decades. Clearly, catalyst choice, in particular topology and acidity, as well as the specific process conditions determine the overall MTO activity and selectivity. However, the subtle balances between these factors remain not fully understood.

An overview of proposed reaction mechanisms for the MTO process will be given. The presence of organic species, that is, the so-called hydrocarbon pool, in the inorganic framework forms the starting point for the majority of the mechanistic routes. Depending on the catalyst topology, reaction mechanisms proposed thus far involve aromatic [3,4] or aliphatic [5] intermediates. Characterization of reaction intermediates is possible using a combination of spectroscopic techniques, such as NMR,[3] IR [6] and UV/Vis [7] spectroscopy. The deactivation of the nanoporous material also depends on many parameters. To date, very few mechanistic routes are reported for catalyst materials of industrial relevance such as the H-SAPO-34 material.[8]

Ab initio simulations taking into account the zeolitic environment can nowadays be used to obtain reliable reaction barriers and chemical kinetics of individual reactions.[9] As a result, computational chemistry and by extension computational spectroscopy have matured to the level at which reliable theoretical data can be obtained, supplying information that is very hard to acquire experimentally. An overview of modern modeling techniques over varying length and time scales will be given and illustrated for reactions and reaction intermediates related to the MTO process.

ABSTRACT: Nanotechnology is beginning to revolutionize many aspects of society, in particular medicine, including improved prevention, diagnosis, and treatment of numerous diseases. This talk will emphasize implantable and non-implantable devices and will summarize efforts over the past decade that have created novel nanoparticles, nanotubes, and other nanomaterials to improve health, energy, and society. Efforts focused on the use of nanomaterials to minimize immune cell interactions, inhibit infection, and increase tissue growth will be especially emphasized. Tissue systems covered will include the nervous system, orthopedics, bladder, cardiovascular, vascular, and the bladder. Due to complications translating in vitro to in vivo results, only in vivo studies will be emphasized here. Materials to be covered will include ceramics, metals, polymers, and composites thereof. Self-assembled nano-chemistries will also be emphasized. Efforts to decrease bacterial attachment and growth on surfaces (such as door knobs, bed railings, etc.) will also be covered. In addition, efforts to develop in situ sensors that can measure cell responses and then respond to such cellular responses will be covered. Concerns over the toxicity of manufacturing nanomaterials for various products will also be covered. Lastly, tissue adhesives that can be applied directly to tissue (such as skin) to regrow such tissues will be covered. In summary, a wide range of nanomaterial applications in health, energy, and society will be summarized in this talk.

TITLE:  Biomass degradation enzymes as industrial biocatalysts for fuel and chemicals
SPEAKER:  Paul Christakopoulos Chemical and Biochemical Process Engineering, Department of Civil, Environmental and Natural Resources Engineering, Luleå University of Technology, Sweden)

WHEN: 07/06/2013, 12:00
WHERE: SALA DE GRAUS, ETSEQ

ABSTRACT: Fossil oil reserves are decreasing, oil prices are fluctuating, and the CO2 released by oil consumption contributes to global warming. Energy production mainly based in the consumption of fossil fuels and this increases rapidly the emissions of greenhouse gas carbon dioxide, the world is warming and we can predict an increase of about 3 degrees in global mean temperature due to CO2 accumulation the next 100 years. Alternative sources are necessary for energy generation, as transport fuel or feedstock for the production of bulk chemicals. Biomass is the only valid alternative for the synthesis of bulk chemicals, and both enzymatic hydrolysis and microbial bioconversion processes are between the key technologies for the conversion of biomass into products of interest. The economic utilization of abundant lignocellulosic biomass as a feedstock for the production of fuel and chemicals would represent a profound shift in industrial carbon utilization, allowing sustainable resources to substitute for, and compete with, petroleum based products. In order to exploit biomass as a source material for production of renewable compounds, it must first be broken down into constituent compounds, such as sugars, that can be more easily converted in chemical and biological processes. Lignocellulose is, unfortunately, a heterogeneous and recalcitrant material which is highly resistant to depolymerization. Many microorganisms have evolved repertoires of enzyme activities which act in tandem to decompose the various components of lignocellulosic biomass. Considering the current dependence on acid and heat-pretreatment in the deconstruction of lignocellulose, it is clear that enzymes that are stable and active at low pH values and at high temperatures are of particular value. Filamentous fungi growing in the plant litter and soil are known to be good sources of polysaccharide degrading and modifying enzymes. Frequently isolated from soil and self-heating compost, the thermophilic, filamentous fungus Sporotrichum thermophile (Myceliophthora thermophila) grows optimally between 45oC and 50oC. Since high temperatures help to solubilize some components of lignocellulosic feedstock and decrease the viscosity of slurries of biomass, thermophilic enzymes would have strong process advantages. Thermophilic enzymes would also have advantages in stability during the course of harsh process conditions, and increased catalytic rates at higher temperatures. The genome sequence of S. thermophile has also come available recently. Overall, these facts make S. thermophile as a very promising source for novel thermophilic enzymes. The enzymes and enzyme cocktails derived from this species would promote the development of advanced technologies for the biomass derived fuels and chemical sector and many other industries. Novel enzyme activities such as feruloyl esterases and glucuronoyl esterases, responsible for the cleavage of lignin-carbohydrate linkages for the tailored made modification of lignin-carbohydrate complexes in order to enhance their biological activity, xylanases, glycoside hydrolases family 61 (GH61) which are capable of enhancing the biomass degrading activity of common cellulolytic preparations via a recently discovered oxidoreductive cellulose degrading mechanism, were functionally expressed in the methylotrophic yeast Pichia pastoris. The role of these enzymes in plant biomass degradation but also their use as biosynthetic tools will be presented in this lecture.

TITLE:  Gas phase synthesis and coating of functional nanoparticles
SPEAKER:  Jorma Jokiniemi (Technical Research Centre of Finland (VTT))

WHEN: 31/05/2013, 12:00
WHERE: Sala de Graus, ETSEQ

ABSTRACT: The rapidly developing field of nanotechnology presents many opportunities and benefits for new materials with significantly improved properties as well as revolutionary applications in electronics, medicine, energy, environment, etc. The industrial production and use of nanoparticles will be the driving force for the emerging new materials industry of the 21st century.

The University of Eastern Finland (UEF) and the Technical Research Centre of Finland (VTT) focus on developing gas phase methods to produce metallic and metaloxide nanoparticles for industrial applications. Gas phase techniques offer several important benefits such as continuous monitoring of the production, minimal use of energy and water, high purity, fast transfer time and a possibility to selectively mix different nanomaterials.

Nanoparticles are of great importance in clean energy technologies. Both environmental concerns and advances in consumer electronics increase the demands on efficient energy storage solutions. Currently lithium ion (Li-ion) batteries with their high energy density and long life-time are, perhaps, the best available technology to meet these demands (Hall and Bain, 2008). However, for the widespread utilization of Li-ion batteries in applications such as electric vehicles, several challenges still remain. These include price, safety, specific energy and power, and the cycle life (Du Pasquier et al. 2003, Wen et al. 2008). To tackle those issues, new materials with high Li-ion capacity and higher stability have been sought, for instance lithium titanate (LTO) and silicon-based materials.

In this presentation, we will look at two gas-phase methods to synthesize nanoparticles for energy applications. First, we will review a single-stage gas phase method for the production of doped lithium titanium oxide (LTO). The particles were synthesised using a flame spray pyrolysis (FSP) system from a precursor solution containing Li-acetylacetonate and titanium tetraisopropoxide. The particles were doped with silver and copper by addition of silver and copper 2-ethyl hexanoic acid directly into the precursor solution. Electrochemical testing of the produced material is also presented.

In the second part, we will review the production of carbon-silicon nanoparticles using high temperature achieved through an induction heating furnace. In this approach, a source metal is placed in a zirconia crucible embedded in solid graphite or other suitable conductor. The system is enclosed in graphite felt insulation. Argon flow carries silicon vapour outside the insulation, where nitrogen sheath flow rapidly cools the carrier flow and the metal vapour forms nanoparticles. The furnace has been tested to withstand crucible temperature up to 2600°C while the temperature of the quenched gas remains below 150°C.

Multidisciplinary Seminar, Friday 10/05/2013

TITLE:  Transcription in structured environments: new opportunities for biotechnological applications
SPEAKER:  George Attard (Department of Chemistry, University of Southhampton)

WHEN: 10/05/2013, 12:00
WHERE: Sala de Graus, ETSEQ

ABSTRACT: Transcription in structured environments: new opportunities for biotechnological applications
Cell interiors are characterized by extreme levels of molecular crowding (due to proteins and nucleic acids) as well as varying degrees of nanostructuring (due to lipid components). As a consequence of the high macromolecular load, cell interiors are highly heterogenous over multiple length scales. Furthermore, the presence of lipids, though making a modest contribution to crowding, leads to the formation of highly structured aggregates with periodic and often anisotropic nano-architectures that effectively reduce the dimensionality of the space in which chemical reactions can occur. Understanding the effects of dimensionality and confinement on chemical reaction rates and selectivity is relevant to guiding our understanding of fundamental biological processes. Of particular interest is the interaction between nucleic acids (dsDNA and ssRNA) and the self-assembled liquid crystalline phases (e.g. inverse hexagonal, inverse cubic) formed bylipids. This is because nucleic acid/lipid mixtures are currently used in experimental approaches for targeted delivery of genetic material, and theyalso provide simple model systems for the organization of the nuclei in eukaryotic cells.
This talk will be concerned with the availability to transcription of dsDNA that is confined into the structured environment of a lyotropic liquid crystalline phase, or that is tethered to a surface. Our main findings are that DNA confined within an inverse hexagonal (HII) liquid crystalline phase is transcriptionally active, that dsDNA readily partitions into preformed inverse hexagonal phases of the zwitterionic lipid DOPE and that ssRNA prefers to reside in the supernatant, unstructured, phase. The possible uses of confined DNA in new types of cell-free transcription-translation systems for biotechnological applications will also be discussed.

Multidisciplinary Seminar

TITLE:  Steam-cracking: an evergreen of the chemical process industry


SPEAKER:  Guy Marin (Laboratory for Chemical Technology, Ghent University, Belgium)

WHEN: 03/05/2013, 12:00
WHERE: Sala de Graus, ETSEQ

ABSTRACT: This lecture will focus on the thermal conversion of fossil or renewable feedstocks to olefins.

Steam cracking can be described by considering a limited number of elementary reaction families not only for fossil (1) but also for renewable feedstocks (2,3). Group contribution methods can be applied to calculate the corresponding kinetic parameters. The group contributions follow from a data base obtained by high level ab initio calculations involving representative molecules and reactions (4-7). Based on this single-event microkinetic (SEMK) methodology a reasonable agreement with pilot and industrial data was obtained for ethane steam cracking (8).

SEMK requires the characterization of a feed stock in terms of types of molecules. Both fossil or renewable feedstocks typically consist of a considerable amount of types of molecules. So-called molecular reconstruction methods use macroscopic properties such as density and boiling point traject to obtain a characterization of the feedstock in the terms required (9,10). Of course they are based on a training set. The latter can be obtained by a GCxGC analysis of typical feeds (11,12).

Process optimization and innovation not only involves feed stocks and reactor technology (13) but should also account for up- or downstream units like the Transfer Line Exchanger (TLE) (14), the convection section (15) and the interaction between the furnace and the reactor coils (16).

TITLE: How to win the snooker game? Alternative energy forms for intensification and control of chemical reactions.

SPEAKER:  Andrzej Stankiewicz (Intensified Reaction and Separation Systems, TU Delft Process Technology Institute, Delft University of Technology, The Netherlands)

WHEN: 30/04/2013, 12:00
WHERE: Aula 117, ETSEQ

ABSTRACT: The control of chemical reaction pathways at molecular level presents undoubtedly the most important scientific challenge on the way to fully sustainable, thermodynamically-efficient chemical processes. Minimization or elimination of waste, reduction of separation operations which are responsible for circa 40% of energy consumption in chemical and related industries and possibility for tailored manufacturing of new, advanced products ­these are the most obvious advantages of a better molecular reaction control.

Despite several Nobel prizes awarded for fundamental works in the area of the reaction dynamics and molecular reaction control (Herschbach, Lee and Polanyi, 1986), chemical reactors developed and used thus far offer a very limited degree of control of molecular events. In those reactors improvement of the Maxwell-Boltzmann distribution in order to bring more molecules at the energy levels exceeding the activation energy threshold occurs conventionally via conductive heating. However, conductive heating offers only a macroscopic control upon the process and is thermodynamically inefficient.

It is clear that in order to meet the future needs of sustainable world, a new generation of chemical reactors, which I call “perfect reactors”, must emerge. A groundbreaking solution in those reactors will consist in creating a reaction environment, in which the geometry of molecular collisions is controlled while energy is transferred selectively from the source to the required molecules in the required form, in the required amount, at the required moment, and at the required position.

The lecture is illustrated with examples of various paths towards “perfect chemical reactors” explored within the Chair of Intensified Reaction and Separation Systems at Delft University of Technology. Those paths include the use of lasers and electric fields to control molecular alignment/orientation
and the local use of electromagnetic irradiation for molecular activation. New concepts of chemical and catalytic reactors based on the above alternative energy forms are presented.

TITLE: Self-Assembly and aggregation of functionalized polyoxometalates. Preparation of Recyclable Catalysts by Post-Functionalization of Hybrid Polyoxometalates.

Abstract: Self-Assembly and aggregation of functionalized polyoximetalates.

Supramolecular chemistry has established the concepts for the self-assembly of complex architectures and smart materials. Organic molecules are often determining the outcome of such processes. Therefore, the attachment of POMs to suitable organic molecules yields organic-inorganic hybrids that are useful constituents for the incorporation of POMs into supramolecular systems.

Beside the discussion of the synthetic chemistry involved, this presentation focuses on two different approaches: i) the grafting of ligands with free binding sites for the self-assembly of supramolecular architectures through the coordination of transition metals. The geometric constrains imposed by the coordination vectors of these ligands determine the outcome of metal complexation, such as coordination polymers or discrete species. ii) the grafting of thermoresponsive polymers for the preparation of smart materials that include POMs. Different synthetic procedures and the characterization of the POM-polymer hybrids will be presented.

Preparation of Recyclable Catalysts by Post-functionalization of HybridPolyoxometalates.

In a collaborative work with Bernold Hasenknopf and E. Lacôte from the “Institut Parisien de Chimie Moleculaire” at the University Pierre et Marie Curie, we developed the preparation and post-functionalization of hybrid polyoxometalates.1 These organic-inorganic compounds with modular redox2 or acidic properties3 are selective homogeneous recyclable catalysts for C-C, C-N or S-O bond formation. We recently demonstrated the positive influence of POM for Gold or Palladium-catalyzed reactions.4 Some of these hybrids are chiral and after having worked toward their kinetic resolution,5 we are now studying them as possible chiral inductors. An overview of that work will be presented.
