Keynote: Topological forms of future of structural chemistry of new substances and materials

Time : 10:00 am-10:40 am

Biography:

Professor Vladimir Ya. Shevchenko obtained pioneering results in the field of chemistry and technology of semiconductor compounds AIIBV, which laid the foundation for their introduction into new technology. Vladimir Ya. Shevchenko was the author of the discovery in USSR 196 of the structural dependence of semiconductor-metal transitions, which allowed predicting new semiconductor materials. He formulated and experimentally confirmed the fundamentals of the dissociative theory of fracture under extreme stresses, which made it possible to create products of special techniques widely used in practice. Currently Vladimir Ya. Shevchenko develops the physicochemical basis of the reaction-diffusion processes of morphogenesis, which determine the topochemical processes of the formation of triple periodic surfaces of minimal energy, which makes it possible to create "physical" cellular structures. Scientific interests: structural chemistry of nanostate, new biomaterials, nanoparticles, nanostructures and nanocomposites; physicochemistry and technology of technical ceramics. 

Abstract:

Topology presents a unique opportunity to look into the physics of materials. Topological states provide a wide range of possibilities for discovering unknown phenomena of Nature. Examples of such states are, for example, the quantum Hall effect or insulators that can conduct electricity along a monatomic layer on their surface.

An interesting geometric relationship exists between the composition of atoms in crystalline materials and triple periodic minimal surface (TPMS). TPMS are observed in Nature in the form of interfaces, for example, in lipid binary layers and block copolymers. Nodal surfaces, the definition of a wave vector in the inverse space of an equipotential surface, soap films, elements of a smooth section of asymmetric domains in a given symmetry group are typical material objects that can be physically significant and which can help in visualizing of significant structures at a level higher than single atoms.

We firstly reported application of ceramic materials with triple periodic minimal surface (TPMS) topology as functional and structural elements. Such complicated structures may be produced only using additive technologies and may be applied for environment protection using catalysts for car exhausts and industrial gaseous and liquid pollutions due to intensification of mass and heat exchange. Also such structures may be used for efficient dissipation of mechanical energy in structures operating under conditions of extreme loads and dissipation of energy of acoustic waves. Details of structural, mechanical and functional properties of TPMS structures will be reported.

We firstly obtained a solid-phase material based on chromium carbide, which has a unique microstructure with the topology of triple periodic surfaces of minimal energy. For the first time, a deep connection between the reaction-diffusion Turing structures and triple periodic surfaces of minimal energy has been experimentally established. The possibility of formation as a result of reaction-diffusion interactions of a material with a microstructure having a topology similar to TPMS is shown. This result opens the perspective of obtaining new types of materials with a regulated microstructure.

Abstract:

Hetrogeneous catalysis is crucial to chemical technology. Innumerable chemical reactions are facilitates by this catalytic systems and, in this context, aliphatic nitro compounds have been demonstrated a great reactivity under heterogeneous catalysis, especially in the formation of new carbon-carbon single and double bonds. Very often the use of aliphatic nitro compounds, combined with heterogeneous catalysis, offer the opportunity to perform the reaction more efficiently, with enhanced chemoselectivity, high purity, improved yields and eco-sustainability.

Thus, a variety of important targets can be obtained from aliphatic nitro compounds, under heterogeneous catalysis.

Abstract:

Various types of radioactive wastes are generated from nuclear facilities and especially contamination of waste is a significant issue for the safety and the environment because of their potential health effects. Various immobilization technologies exist for stabilizing the radioactive waste in a stable matrix.  Ordinary Portland Cement (OPC) is a commonly used encapsulant for nuclear waste. OPC is generally mixed with additives and radioactive liquid waste is immobilized it this matrix.

Various polymers were investigated instead of OPC. Such as; Vinyl Ester Styrene (VES), Advanced Polymer System (APS) epoxy and another type of epoxies. Most of these new immobilization technologies have some advantages to OPC. They have better compressive, tensile, flexural strength and they are stronger than cement.  Polymer achieves maximum strength quickly with gelation behavior.  Setting time of polymer matrix depends on process temperature.  Generally, viscosity properties comply with Newtonian behavior. Research results show that exponential increase in viscosity as curing progress and dimensional changes of polymers shrink during the curing period.  Polymers have better leaching performance than OPC matrix.  They have lower heat capacity and thermal conductivity than cement. These properties are important for long-term isolation of nuclear waste.

The main reason for immobilization of nuclear waste is to prevent contamination. Contamination occurs basically in two mechanisms. These are; migration by water and dissemination by air.  By these mechanisms, radioactive particles from the waste matrix cause contamination in water or air.  An important reason for using polymers is polymers do contain water.  Polymers have many desirable features as encapsulants. Such as; High strength, Low permeability, Compatibility with ‘difficult’ wastes, Radiation tolerant level. For these reasons, polymers are more suitable material for immobilization of nuclear waste in long-term.

Session Introduction

Denis Bouyer

Professor, European Institute of Membranes (IEM), Montpellier, France

Title: From polymer solution to porous membrane – controlling the membrane morphology using a modeling approach

Time : 12:25 pm-12:55 pm

Speaker
Biography:

Prof. Denis Bouyer is a full Professor in European Institute of Membranes (IEM), Montpellier, France. He is team leader of Chemical Engineering department and has fourteen years’ experience in polymeric membrane preparation. His membrane research activities involve the modeling of the polymeric membrane formation, such as mass and heat transfer and/or chemical reactions. Recently, he investigated the membrane formation dynamics using the phase field method (based on Cahn-Hilliard equation). From 2003, he has supervised 16 PhD and during the last decade he was been involved in 7 industrial collaborations and in 10 ANR projects (2 international) on Membrane Technologies and he was coordinator of 3 ANR projects. He has also published more than 50 international peer-reviewed articles, three patents with international extension and 3 book chapters. He is guest editor for a special issue “modeling the membrane formation” for the international journal “Membranes (ISSN 2077-0375)”.

 

Abstract:

The modeling of membrane formation is a very tricky but exciting challenge, which could help preventing the classical trial-and-error process classically used by industrials to adjust the operating parameters. In a recent past, numerical models have been developed for simulating the mass transfer phenomena prior to phase inversion. They involved Flory Huggins theory (thermodynamics) and free volumes theory (diffusion of small molecules in the polymer matrix).

In IEM, we recently developed a new type of membranes in agreement with principles of green chemistry, i.e. with water soluble polymers (HPC, PVA) and without the use of organic solvent. For such case, the phase separation was induced by an original LCST-TIPS process, i.e. the polymer solution was heated above the Lower Critical Solution Temperature (LCST). The crosslinking of the polymer was carried out by chemical cross-linking using the Glutaraldehyde (GA) to prevent resolubilization in aqueous solution during further filtration. Hence, concomitant phenomena were thus involved in the membrane formation mechanisms: (i) phase separation, (ii) chemical cross-linking and (iii) solvent evaporation.

The modelling approach was developed to calculate the evaporation rate during the phase separation and the model involved: (i) the Flory-Huggins theory for simulating the thermodynamics of the polymer system, (ii) mass transfer within the polymer matrix based on free-volume theory and RMN experiments for self-diffusion coefficients, (iii) dedicated diffusion formalisms for diluted systems, and (iv) semi-empirical correlations for the external mass transfer. A system of partial differential equations was solved to simulate and predict the composition path during the phase separation process, from the polymer solution to the dry porous membrane.

Thanks to the numerical model, the most appropriate operating conditions were therefore determined to obtain a porous membrane with appropriate morphology for friltration.

Session Introduction

John L. Zhou

Professor, University of Technology Sydney, Australia

Title: In situ Photocatalysis of Emerging Contaminants in Groundwater Using Air-Clad Optical Fibres

Time : 14:00 pm-14:30 pm

Speaker
Biography:

Professor Zhou is an environmental engineer interested in contamination remediation and energy recovery from waste. Following a PhD in environmental technology, he has worked in the UK and Australia. He is a panel member/assessor for funding agencies such as the EU, UK EPSRC, NERC, Defra, Royal Society, US NSF, Fondazione Cariplo of Italy, and ARC. He is a recipient of K.C. Wong science research prize, Royal Society of Chemistry J.W.T. Jones travelling fellowship, and Royal Society research grant. He has published 170 articles in environmental and energy journals, with 10 being ESI highly cited.

 

Abstract:

Photocatalysis of emerging pollutants under visible irradiation is a process that has attracted wide research interest. However, these studies are limited to bench scale, since the catalysts utilised are added in slurry form and also the light from the source cannot penetrate to the bottom of the reactor. Optical fibres allow the light to be transmitted to longer distances with minimum loss, potentially making bench studies practical in real environments. The objectives of this research are to utilise air-clad fibres to transfer light to the photocatalysts immobilised onto glass beads, to collapse the air-cladding to attain side-emission enabling successful light transmission to the catalysts, and to photodegrade emerging contaminants such as 17α-ethynylestradiol (EE2) an endocrine disrupting chemical. This study addressed two major drawbacks of suspended photocatalysis: the immobilisation of catalysts and the transmittance of light over greater distances. Efficient side emission from the fibres was obtained by collapsing the air-holes, P25 and 4 wt.% Au-TiO2 catalysts were immobilised onto glass beads. EE2 half-lives were 1.26 h-1 and 0.78 h-1, in the presence of P25 TiO2 and gold modified catalysts respectively. The rate of photodegradation by both catalysts was found to follow pseudo 1st order kinetics. The catalysts as well as the fibres were stable for multiple reaction cycles with 6% decrease in degradation efficiency after three cycles. Therefore, air-clad fibres are a promising mode of light transmittance for photocatalysis applications in contaminated groundwater.

 

Michael Badawi

Asst Professor, University of Lorraine, France

Title: In silico design of nanomaterials for environnemental and catalytic applications

Time : 14:30 pm-15:00 pm

Speaker
Biography:

Abstract:

Nowadays the degree of sophistication of atomistic simulations based on density functional theory (DFT) can be very high and "numerical experiments" can be realized [1-5]. Combining different atomistic simulation techniques such as ab initio molecular dynamics with advanced method such many-body schemes to take into account non-local dispersion forces, one can accurately predict adsorption enthalpies of molecules in nanoporous materials. This allows a fast screening of a large number of formulations to design efficient and selective adsorbents with optimized properties for various applications. The use of atomics simulations also helps to understand at a molecular level the interactions between molecules and materials. We will give some applications of these modeling tools for the selective capture of radioactive iodine in case of nuclear severe accident [1-4] and for the production of biofuels from biomass waste [5]. Surface or catalytic reaction mechanisms can be also computed to identify the key steps in a specific process [4,5]. In close connection with experiments, this theoretical methodology open the path to an integrated approach for the development of optimized nanomaterials and processes in the fields of catalysis and environment.

Abstract:

This communication discusses a comprehensive review of biomass energy sources, environment and sustainable development. This includes all the biomass energy technologies, energy efficiency systems, energy conservation scenarios, energy savings and other mitigation measures necessary to reduce emissions globally. The current literature is reviewed regarding the ecological, social, cultural and economic impacts of biomass technology. This study gives an overview of present and future use of biomass as an industrial feedstock for production of fuels, chemicals and other materials. However, to be truly competitive in an open market situation, higher value products are required. Results suggest that biomass technology must be encouraged, promoted, invested, implemented, and demonstrated, but especially in remote rural areas.

Speaker
Biography:

Dr.-Ing. Mohammad Aleysa is an expert in the environment-friendly combustion technologies. From his position as a group manager of the Combustion – and Environment Technologies and a head of the accredited and notified test laboratory of Firing Systems and Chimneys in Fraunhofer Institute for Building Physics IBP in Stuttgart/Germany seeks to find new constructive concepts and technologies as preventive measures that aim to minimize the formation of dust and gaseous pollutants. His latest achievement based on improving new smart monitoring and controlling systems for the pre-determination of the combustion quality in small-scaled combustion systems.

 

Abstract:

Biomass as a renewable energy source is gaining increasingly importance due to the unpredictable price development and the scarcity of fossil fuels. However, the increased energy use of biomass must not lead to an increase in harmful pollutant emissions in residential areas and should promote the development of innovative combustion technologies which not only ensure an economic and ecological energy supply but also have to be modernized and regulated in such a way that they can be integrated into the existing intelligent energy management systems in buildings or other facilities.

Within this scope an innovative technology combination has been developed for a better combustion quality and higher efficiency of the thermal utilization of biomass small-scaled combustion systems:

  • Integrated Cyclone-Packed Technology

It represents an integrated flue gas treatment measurement for the combustion of biomass in small-scaled combustion systems. This primary measurement comprises a cyclone as the main combustion chamber and the packed technology as a post treatment step. Optimum 3-Ts (high temperature, intensive turbulent, enough residence time) are fulfilled in the Cyclone-chamber due to the recirculation effect of the cyclone. The relevant emission reduction through Integrated Cyclone-Packed Technology results from the improvement of the combustion in critical operation phases, in which over 90% of the total emissions produced in the conventional gasification boilers is drastically minimized. Furthermore, a minimum increase of the boiler efficiency of 15%, in practice, with corresponding fuel and CO2 savings can be guaranteed.

  • Combustion Management and Monitoring System

The concept of monitoring system is based on regulating the combustion process with the minimum but sufficient oxygen for the completeness of combustion, regardless of the combustion concept or technique or even the fuel used. A novel O2/COe-sensor (oxygen-and-carbon-monoxide-equivalent-sensor) is used. This O2/COe-sensor can simultaneously detect both the content of oxygen and carbon monoxide equivalent in the exhaust gas as an important indicator for the combustion quality and its completeness. A particular advantage of this monitoring system is that the combustion quality can be determined and the emission level can be monitored and comprehensively evaluated during the operation.

The use of the integrated Cyclone-Packed Technology and the Combustion Management and Monitoring System not only can ensure compliance with the limit values of the European regulations in continuous operation but also can offer more cost-effective and competitive combustion technologies for the thermal utilization of biomass and other biogenic fuels in small-scaled combustion plants.

Title: Green synthesis of copper nanoparticles using biological Cynomorium Coccineum L. and Nerium Oleander extracts and study of their interaction with organic pollutants

Time : 16:30 pm - 17:00 pm

Speaker
Biography:

Dr. Mahjoub Jabli has his expertise in the valorization and chemical modification of natural products for environmental applications. He got his doctor degree in polymer and textiles since 2012. He is an associate professor in the same field at High Institute of Technological Studies (ISET of Ksar Hellal) Monastir Tunisia. He is an active researcher and he published till to now more than 26 articles in international journals.

 

Abstract:

The synthesis of nanoparticles has, progressively, gained more attention due to the important characteristics that they provide including a large surface area, small size, and other physicochemical parameters. This feature makes nanoparticles have multiple applications in various fields. Herein, the current investigation highlights the use of an ecological synthetic procedure to reduce copper sulfate into copper oxide nanoparticles using biological molecules of either Cynomorium Coccineum L. or Nerium Oleander extracts. FT-IR spectrum data reveal that the natural extracts were rich of carbonyl groups, phenolics, and other reducing agents which are responsible for the green synthesis of copper nanoparticles. SEM analysis showed that the nanoparticles vary in size and shape distribution due to the chemical composition of the studied extracts. The purity of the metal particles was proved by EDX analysis showing the presence of elemental copper oxide. The crystalline nature of the prepared nanoparticles has been confirmed using the XRD analyses. The prepared biological nanoparticles were, further, studied to interact with organic pollutants such us textile dyes. Methylene blue dye was chosen as a model. Experiments were performed under the change in initial dye concentration, adsorption dose, contact time and pH value. The equilibrium adsorption capacities were 81.2 mg/g and 64 mg/g using nanoparticles synthesized from Nerium Olenader and Cynomorium Coccineum L., respectively. These values represent a level comparable to some other common sorbents. In summary, biosorption effectiveness and environmental aspects of the prepared biological nanoparticles make them an ideal alternative to other expensive treatment methods.

Currently, his main research interests are magnetic isotope effects and nuclear spin catalysis in biology, chemical nano-bionics, reliability (robustness) and aging of biological systems.

 

Abstract:

Cells are composed from atoms of chemical elements, many of which have magnetic and nonmagnetic stable isotopes. In molecular and chemical physics, magnetic isotope effects (MIEs) have long been known for a number of magnetic isotopes, among them 13C, 17O, 29Si, 33S, 73Ge, and 235U. Not long ago, MIEs were discovered in the experiments with the living cells enriched with the magnetic isotope of magnesium, 25Mg. Moreover, MIEs were revealed in the experiments with one of the most important molecular motors of cell bioenergetics, myosin isolated from smooth muscle. The rate of the enzymatic ATP hydrolysis is 2.0–2.5 times higher with 25Mg than that with the nonmagnetic 24Mg or 26Mg. Besides, MIE was revealed with zinc. While Zn2+ performs the cofactor function less efficiently than Mg2+, it was found that the rate of the ATP hydrolysis driven by myosin is 40-50 percent higher with the magnetic 67Zn as compared to the nonmagnetic 64Zn or 68Zn. Furthermore, the beneficial MIE of 25Mg was discovered in the ATP hydrolysis catalyzed by mitochondrial H+-ATPase isolated from yeast cells and reconstituted into the proteoliposome membrane. On its own, factual evidence of MIE unambiguously indicates that there is a spin-selective rate-limiting step, the “bottle-neck” in the chemo-mechanical cycle of the enzyme that is accelerated by the nuclear spins of 25Mg or 67Zn. Although detailed mechanisms of ability of the biocatalysts to perceive the nuclear magnetism require further investigations, there are the grounds to believe that this new field, nuclear spin catalysis, highlight promising venues for future research in catalysis with possible application of the stable magnetic isotopes in medicine for creating novel anti-stress drugs including the low-toxic anti-radiation protectors. Besides, it opens novel ways for control over efficiency and reliability in optical communications, quantum information processing, computational schemes and the like.

Her main research interest has focused on simulation of the production processes of petroleum and petrochemical products, and modeling and optimization of treatment, extraction and transformation of renewable resources to biofuels.

Abstract:

Fossil fuels are still being formed by underground heat and pressure; however, they are being consumed more rapidly than they are being created.  For that reason, fossil fuels are considered non-renewable. The large fall in price of fossil fuels, its inevitable depletion properties, and   increasing the world environmental  pollution resulted from the large usage of  low grade of crude oils, all are behind the believe that biofuels are the alternatives and promising sources of energy for future, owing to their renewability and less pollution impact. The current work deals with highlighting an innovative route for intensifying the biofuel manufacturing processes, it is the coupling of texturing the raw natural material by an innovative technology; the Instant Controlled Pressure Drop (DIC) which is a thermo-mechanical high temperature short time treatment process with the conventional transformation processes of the raw materials to biofuels. To decrease the number of experiment, chemicals and efforts in  biofuel production processes, Response Surface Methodology as effective tool for optimization and modeling  the effects of the operating parameters relevant to the biofuel manufacturing process and  those related to the DIC process (temperature, pressure and heating time), on yield and characteristics of the biofuels is recommended and will be demonstrated. The new production approach may highly contribute to increase the broadening worldwide replacement of the petroleum derived transportation fuels with biofuels to support the energy supply and minimize at the same time the global warming.

Hanae Ouaddari obtained her engineering degree from Ecole Mohammedia des Ingénieurs in 2004 into Industrial Process Engineering (Major). She then joined the National Center for Scientific and Technical Research as Laboratory Manager for Atomic Emission Spectrometry. In 2015 she joined the Laboratory of Materials Membranes and Environment of Faculty of Sciences and Technologies of Mohammedia, University of Hassan II as PhD student.

Her current research interest include the valorization of Moroccan clays for environmental applications to catalysis, adsorption and ultrafiltration.

 

Abstract:

Developing effective approaches for synthesizing catalysts is currently a top priority. Here, we report the preparation of natural catalysts from modified clay (MC). Three types of clay's were tested and compared in this present study. It is noteworthy that clay samples are of Morocco origin. The resulting materials were characterized by X-ray diffraction (XRD), Fourier transform-infrared spectroscopy (FT-IR), Transmission electron microscopy (TEM), Scanning electron microscopy (SEM), X-ray Fluorescence Spectrometry (X-F), and energy dispersive X-ray spectroscopy (EDS). We also demonstrate that these materials have catalyzed the synthesis of α,β-unsaturated carbonyl compounds an effective way in terms of efficiency, processes and selectivity in water as solvent. It must however be noted that these compounds are a crucial importance in fine chemistry1,2; they are used as intermediates to synthesize other high-value-added products3. The results revealed that the MC's samples show a high-efficient catalytic activity when compared with natural clay samples. The influence of catalyst weight, and recyclability were also achieved. Several aldehydes and activated methylene are tested to prepare about numerous alkenes. The influence of the nature of substitution was also studied.
