Abstract

In our laboratory, we are mainly studying on Schiff base metal complexes which are composed of various metal ions and organic ligand components. They are designed and synthesized skillfully, and are elucidating structures and electronic properties by using various methods such as X-ray crystallography, (spectroscopic) measurements of physical properties and theoretical calculations. Basic research works of an investigation of knowledge about  principle of structures and electronic state (physical inorganic chemistry) and are our core competence. Interpretation of electronic absorption and circular dichroism (ABCD) spectra and determination of absotute structure of optically active complexes by X-ray crystallography are historically important issues in the field of coordination chemistry especially in Japan. Recently, as the application of such fundermentals, we are dealing with  hybrid functional materials of supramolecular complexes exhibiting  multiple physical properties aiming at environmental or energy materials such as DSSC, light-driven biofuel cells, and photocatalysts. Our reserch concept of ”hybrid systems of chiral metal complexes” were proposed by combination of chiral metal complexes having sufficient accumulation and new  functional nano-materials (metal complexes, magnetic materials, semiconductors, metallic nanoparticles, catalysts, optical function pigments, synthetic polymers and metalloproteins, etc.). As for physical measruemets, we are using “topological lights” such as linearly and circular polarized light, optical vortex, and free electron laser for both optical illumination and spectral interpretation of these inorganic hybrid materials. In this planary lecture, I will present both our concept (including a wide element of an inorganic chemistry from solid state chemistry to bioinorganic chemistry) and some our recent results.

Abstract

The objective was the analysis of how the innovation process occurs in the brazilian green plastic supply chain, by replacing a non-renewable resource (naphtha) for a renewable one (ethanol from sugarcane), focusing the focal organizational, considering the sustainability perspective. It was qualitative research, exploratory and descriptive, using a case study. It was thirteen interviews considering Braskem as the focal organization. It was used the diamond of the total innovation for analysis. In the results, the characteristics of green plastic extrapolate the nature of technological innovation. The sustainability of the product is linked to the use of renewable input (ethanol from sugar cane), highlighting the fact that the carbon dioxide is captured from the atmosphere over the cultivation of sugarcane, remaining fixed during the life cycle of the product. In reality, it was a substitution of a non-renewable resource (naphta) by an entire Brazilian sugarcane supply chain. The biopolymers development is justified by the oil finiteness and its aggravating the greenhouse gas emissions. This development was possible due to climate advantages obtained by the production of sugarcane and the amount of available land for cultivation in Brazil. The focal organization was able to induce innovation in their entire supply chains, determining which upstream and downstream effects to offer the green plastic innovation for users. The  capture of carbon dioxide led to reduction of greenhouse gas emissions. It is inferred that the Conduct Code for Braskem Ethanol Suppliers was the main upstream factor that triggered these outcomes. The main downstream effects developed by the focal organization are related to the environmental importance suggested by this product. Potential clients have been identified by the focal organization and, for them, the I’m green™ mark was created, which can be considered a major downstream spillover.

Abstract

The world demand for energy has led oil companies to expand their operations in cold environments such as the offshore deepwater and onshore for more reservoirs. During hydrocarbon production in the cold environment, these oil companies are challenged with the problem of wax deposition from the crude oil building up on the pipe wall. It leads to increases in operational and remedial costs while suppressing oil production. Wax inhibitors are one of the mitigation technologies that had been examined its influence on crude oil viscosity and wax appearance temperature (the temperature at which the first crystal of wax start to deposit from crude oil). During this work, the performance of some of wax inhibitors such as acetone, copolymer + acrylated monomers coded W804, and copolymer + acrylated monomers coded W805 was evaluated to determine their effects on the crude oil rheology, using the programmable Rheometer rig at gradient temperatures 55 to 0°C and shear rate 120 1/s. The synergy of using mixtures of such chemical inhibitors has been examined by adding 250, 500, 1000, 1500 and 2000 ppm of the mixtures of inhibitors to the crude oil. The first mixture includes acetone with copolymer + acrylated monomers (W804), and the second mixture includes acetone with copolymer + acrylated monomers (W805). These mixtures works well compared with its original components. The wax appearance temperature of the used crude oil in this study without inhibitors is 30°C. The first mixture of inhibitors reduced the wax appearance temperature of oil to 25.2, 24, 18.4, 16.8, and 15.4°C, at concentration 250, 500, 1000, 1500 and 2000 ppm respectively. While, the second mixture of inhibitors reduced wax appearance temperature of the crude oil to 24.3, 21.7, 16.7, 15.3 and 14.2°C, at concentration 250, 500, 1000, 1500 and 2000 ppm respectively. This blend of the inhibitory properties and significant reduction in wax appearance temperature and oil viscosity is providing a unique contribution in wax elimination methods.

Abstract

Increasing energy consumption requires new solutions that offer both high efficiency and clean energy generation. A great share of electrical energy is produced from fossil fuels, which continued use contributes to the greenhouse effect. Alternatively, a certain amount of the energy demand could be fulfilled in a more environmentally friendly manner by using volatile renewable energy. Its integration into the energy system is not possible without appropriate energy storage systems and results in significantly reduced overall efficiency. Solid oxide fuel cell systems (SOFCs) appear to be a promising technology that provides direct conversion of the chemical energy of gaseous fuels into electrical energy without additional conversion steps, with high efficiency and low pollution. The high operating-temperatures and very good catalytic performance enable a high degree of fuel flexibility, in addition to the internal reforming of hydrocarbons. The high-quality heat that is by-product of SOFCs can be used to heat single-family houses, or for industrial processes, thus increasing their overall efficiency. Thus, SOFCs have emerged as the most efficient fuel cell technology. This work will address topic of a future-oriented fuel cell technology and it will introduce its basic principles. They involve the working principle and typical losses that detract from the fuel cell maximum efficiency. Furthermore, the electrochemical characterization techniques and analysis methods used for the electrochemical in-situ investigation will be introduced and discussed. Eventually, this work will provide answers to several important questions: What are fuel cells? How do they work? How can fuel cells improve our energy supply, and, how well can the emission reduction objective be achieved when using this technology?

Abstract

In the active search for a new source of energy which includes its rational utilization and storage, surface energy (a 2D energy) appears now as a challenging option thanks to new available porous materials of all sorts. In particular, large surface energy can be developed using highly porous Heterogeneous Lyophobic Systems (HLSs) which comprise a highly porous solid and a non-wetting liquid to make working bodies. Such systems exhibit high energy capacity, capability to simultaneously store (and restore) both thermal and mechanical energy, and even electric energy, during intrusion /extrusion of the liquid during compression/decompression operations. Usually an HLS is in the form of a suspension of a porous powder in the liquid. Scanning transitiometry, e.i. P,V,T–calorimetry, can judicially be used to submit such suspension to compression/decompression in a perfectly controlled thermodynamic way over extended  T- and P-ranges.  Depending on the nature of the porous solid and of the non-wetting liquid it is always possible to find a high enough pressure to force the intrusion by compression of the liquid into the pores of the solid. The compression energy being stored in the system can be further restored. Thermal and mechanical energies generated during repeated compression/decompression cycles are recorded simultaneously with the associated P,V-diagrams. Recent experimental measurements demonstrate that original devices making use of selected HLSs can serve as working bodies to store/restore energy, with systems behaving like molecular springs or showing negative thermal expansion.

Abstract

In this work, we used spectroscopic and microscopic techniques to investigate the interaction mechanism between uranium and microorganisms which including the Gram-positive bacteria (Bacillus mucilaginosus) and Gram-negative bacteria (Shewanella putrefaciens) and fungi (Saccaromyces cerevisiae). According to scanning electron microscope couple with energy dispersive X-ray detector analysis, the lamellar uranium phosphate precipitation was only observed on the living and the resting microorganisms. The Fourier transform infrared spectroscopy spectrum also indicated the important role of phosphate groups in forming U(VI)-phosphates precipitation. The X-ray diffraction analysis identified the phase of U(VI)-phosphate precipitation as UO2HPO4·4H2O. Batch experiment that the three types of microorganisms all had high biominerilization ability to U(VI) in the absence of additional nutrients at pH 5, the maximum uranium biominerilization amount could be up to 168-248 mg/g biomass (dry weight) when exposing living microorganism to U(VI) aqueous solution for 1 h. With the extension time from 1d to 7d, less uranium could be extracted by 0.1 mol/L HNO3 from the three types of microorganisms. The precipitate was further evidenced by extended X-ray absorption fine structure spectra based on the presence of U−P shell, which demonstrated that hydrogen uranyl phosphate became the main products on the living microorganisms with prolonged reacting time. After ashing and hydrothermal process, the precipitated U(VI) on microorganism could be converted into UO2 (50-100 nano-sized globular crystals) and K(UO2)(PO4)·3H2O. Our findings offering a more effective strategy for the bioremediation of uranium contaminated water and have significant implications in elucidating the potential role of bacteria in the migration of uranium in geological environment.

Abstract

In this presentation, precision synthesis of polysaccharide-based functional polymeric materials by enzymatic approach is reported. The enzymatic approach has been identified as a useful tool to precisely synthesize functional polysaccharides, which have been interestingly much attention as new biomedical and tissue engineering materials. Phosphorylase is one of the enzymes that are practically used as the catalyst for synthesis of polysaccharides with well-defined structure. Phosphorylase-catalyzed enzymatic polymerization is progressed by using a-d-glucose 1-phosphate and maltooligosaccharide as monomer and primer, respectively, to produce amylose. As the polymerization is initiated from the primer, it can be conducted using primers covalently immobilized to other polymeric materials (immobilized primers), giving rise to amylose-grafted polymeric materials. By means of the property of the spontaneously formation of double helix from amyloses, the phosphorylase-catalyzed enzymatic polymerization using the immobilized primers produces network structures composed of the double helix cross-linking points (Figure 1). In most cases, furthermore, the enzymatic polymerization solutions turn into hydrogels (Figure 1). For example, the phosphorylase-catalyzed enzymatic polymerization using maltooligosaccharide-grafted chitin nanofibers produced amylose-grafted chitin nanofiber hydrogels. Moreover, microstructures, which were hierarchically constructed by lyophilization of the hydrogels, were changed from network to porous morphologies depending on the molecular weights of amylose graft chains.

Abstract

The threat to the South African environment from acid mine drainage and mine-impacted waters is well documented. Effluents from the gold- and coal-mining industries can severely impact upon the quality of water supplies and affect all major industries across the value chain. Substantial volumes of water can, however, be made available through the reuse of treated acid mine water. The waste waters could be treated to levels that ensure that they meet “fitness-for-use” guidelines for alternative applications such as agriculture, sanitation or use in other industrial processes, reducing the treatment cost required for potable water production. The aim of this ‘reuse philosophy’ would ultimately be to reduce potable water consumption and subsequently have a positive effect on water conservation on both a local and international level.To this end Mintek has developed several technologies for the treatment of mine impacted waters, including: The SAVMINTM process developed for sulphate removal from mine impacted water.  The four-stage chemical precipitation process, including heavy metal precipitation, ettringite precipitation, carbonation and recovery of aluminium hydroxide via ettringite decomposition, can reduce the sulphate content of the effluent to below drinking water standards, while simultaneously precipitating the heavy metals present in the water. Passive biological sulphate reduction, a low-cost, low-maintenance technology, aimed at treating relatively low volumes of mine waters and effluents emanating from existing processes, and especially after mine closure, to produce effluents containing sulphate concentrations within the limits specified by regulations for discharge or re-use. Nano-enabled membranes and resins for removal of pollutants and pathogens from water at low cost and high efficiencies. This paper will describe the technical development of the different technologies, including laboratory-scale and pilot plant design.  Based on the water quality data for each treatment technology, various reuse options will be discussed.

Abstract

Arsenic and antimony are metalloids, naturally present in the environment but also introduced by human activities. Both elements are toxic and carcinogenic, and their removal from water is of undeniable importance. Hence, present research work conducted for removal of As(III) and Sb(III) from synthetic groundwater using chemically-modified biomass of marine green algae Posodonia Oceanic (PO-Fe nanocomposite). The PO-Fe nanocomposite was characterized using XRD, FTIR, EA, BET, RMN, SEM, TGA and DSC analysis. To achieve maximum adsorption capacity several parameters such as contact time, pH, adsorbent dosage, initial concentration and temperature were optimized. Adsorption kinetics results of individual and simultaneous arsenic and antimony were analyzed using the pseudo first order, pseudo second order, intra-particles diffusion and the Boyd model. The adsorption isotherm using Langmuir, Frendlich, Temkin, Elovich, Dubinin–Radushkevich (D–R) and Dubinin–Astakhov (D–A) have also been studied. The present adsorption process is capable to reduce the As(III) and Sb(III) concentration from synthetic groundwater to below 10 µg/l and 5 µg/l, respectively, which are maximum contaminant level of these elements in drinking water according to WHO guidelines.

Abstract

Steel framing supporting cast-in-place reinforced concrete slab was historically being constructed using propssupported replaceable shutter system. Later, most commonly, the concrete slab is cast upon permanent cold formed steel deck which itself is supported on steel I-shaped sections. This system makes construction easy and saves time by eliminating props-supported replaceable shutter system. Permanent metal deck serves as shutter system and sometimes designers consider it as bottom reinforcement providing re-bar for top reinforcement only. But metal deck is vulnerable to fire which requires expensive fire protective measures whether it is considered as bottom reinforcement or not. Metal deck itself bear full construction load as shutter during casting of concrete slab on it. For this reason, I-beams are spaced closely to support metal deck and virtually cost of steel frame increases. So, research and study is required to develop alternate solution against props-supported replaceable shutter and permanent metal deck system. After long practice, study and research; a new design idea and construction technology has been developed by us to convert the metal deck as shutter. This new shutter is self-supported, suspended and continuously re-usable without any props. Weight of steel frame reduces by increasing spacing of I-beams. No fixed metal deck is required and fare face finishing of ceiling is achieved. No prop is required under ceiling to support shutter. So, other construction works also progress simultaneously under ceiling which saves construction time. Additionally ceiling plaster, paint, costly fire proof spray and false ceiling may be avoided. So, significant cost and time saving is possible without an significant construction difficulties. Steel I-beam supported reinforced slab may be designed as composite beam using shear connectors to make floor I-beam further economic. Already, first time, this technology has been successfully used conforming all advantages mentioned above in a four storied steel framed building for garments factory in Bangladesh having 4500 square meter slab per floor. There is lot of options for further development of this construction technology. Initially production cost is two to three times more than metal deck cost, but it may be used minimum fifty times after production. So it is highly cost effective.

Abstract

High-temperature solid oxide fuel cell (SOFC) technology mmarks a significant step towards emission-free energy and fuel production, thus creating a global sustainable energy system. SOFCs are highly efficient when operating in both partand full-load modes, due to direct conversion of chemical energy into electrical energy. ompared to low-temperature fuel cells, which require noble metals as catalysts and pure hydrogen as fuel, SOFCs offer great fuel flexibility and use affordable nonprecious metallic catalysts. Furthermore, they have a great fuel flexibility and can use not only hydrogen as a fuel, but also various carbon-containing fuels, such as methane, diesel reformate, etc. Fueling SOFCs with conventional or biogenic fuels under certain operating conditions can, however, result in carbon formation on the cell and cause fuel cell degradation, which significantly shortens the cell’s lifetime. In order to extend the lifetime of SOFCs and to ensure safe operation for both the stationary and mobile application, a deeper understanding of relevant degradation phenomena must be intensified. For that purpose it should be possible to timely discover the nature of the ongoing degradation mechanisms by analyzing the available measurement data, predict their trends and suggest countermeasures in order to keep the device within safe margins, extend its life span, and facilitate its maintenance. The methods and principles used to this end will be shown within this study

Biography

Feroz Alam has invented a structural concept for mega tall buildings which can build one kilometer tower where no additional structural supporting systems are required like belt truss, outriggers and bracings etc. This structural concept also overcame previous disadvantage of shear lag effects of tube concept. A book (ISBN: 978-3-639-66041-8) published completely on his innovative concept from scholars press omniscriptum germany. He published many articles on tall building structural concepts. He worked as a design engineer in Bangladesh, Saudi Arabia & Dubai where he involved for high-rise building designs (steel & concrete). Presently he is working for advanced design concept in bangladesh as a principal design engineer. He designed a 54 storied building in Doha, Qatar. He is also invented a concept for reduction (around 8 to 10%) of concrete from shear walls of tall buildings without affecting the structural integrity of the buildings

Abstract

Structural system of tall buildings have undergone dramatic changes since the demise of the conventional rigid frames in the 1960s as the predominant type of structural system for steel or concrete tall buildings. There are numerous structural lateral systems used in high-rise building design such as shear frames, frames with shear core, framed tubes, tube in tube, super frames which can construct for up to 140 stories. Later developed structural systems like outriggers and the buttress core has allowed for even higher buildings, can design for up to 160 stories. This study is intended to model an advanced structural system for tall buildings which can build taller than the tallest existing one in the world. In this innovative concept, ‘’One Kilometer Mega Structure’’ analyzed where several parallel shear walls have been arranged in both directions and connected with beams and slabs. The shear walls are continuous down to the base to which they are rigidly attached to form vertical cantilevers. Their high in plane stiffness and strength make them well suited for bracing buildings up to about 278 stories (where drift at top 1930mm, allowable H/500 = 2000mm). Dynamic analysis of this I KM tower shows that the habitable floor is at height 723m (Record breaking habitable height at 201 storied) besides, by introducing TMD can make the top habitable. Also it is found by research that, when this structural arrangement is applied to around 831m tall structure with aspect ratio 8.14:1, no additional structural supporting system is required & habitable floor is at 831m (231 stories). Whereas existing world tallest one have habitable floor at 535m (160 stories). This shear walls arrangement is applicable for tall buildings of any height to avoid additional supports to resist the lateral forces while taking advantage of the creative approach of this concept.

Abstract

We isolated and reported (J. Hazardous Materials (2009) 171, 268-272) a bacterial strain of Paracoccus sp. strain DMF from a domestic waste water treatment plant. This strain could completely biomineralize up to 5 g/liter of N,
N- imethylformamide (DMF). We have subsequently completed the annotation of the complete genome of this organism. We have also cloned and expressed some of the genes involved in the degradation pathway and expressed the same in E. Coli. The protein dimethylformidase(DMFase)- the first enzyme in the degradation of DMF, is a 201 kDa hetero tetrameric (α2β2) enzyme. The primary sequence of this particular amidohydrolase indicates that DMFase is a novel kind of amidase. It converts each molecule of DMF into one molecule of formate and one molecule of dimethylamine. The recombinant and native proteins were purified, crystallized and its structure solved by a combination of cryo electron microscopy and X-ray techniques. The structure based catalytic mechanism of this amidohydrolase will be discussed.

Abstract

Ce-BTC, a kind of lanthanide metal organic frameworks, is characterized by large surface areas and good thermal stability. The incorporation of noble-metal nanoparticles in MOFs (Metal Organic Frameworks) have attracted much attention in catalytic field. We utilized in situ MOFs growth strategy to synthetize Pt@Ce-BTC that Pt nanoparticles was pre-stabilized by polyvinylpyrrolidone. X-ray diffraction, Fourier transform infrared, scanning electron microscope and transmission electron microscopy demonstrated the integral structure and excellent crystallinity of Pt@Ce-BTC with no Pt nanoparticles aggregation. Nitrogen adsorption-desorption results exhibited that both the Ce-BTC and Pt@Ce-BTC displayed type â…  isotherms which indicated microporosity. The obtained Ce-BTC and Pt@ Ce-BTC were diluted by quartz sand and loaded in a continuous flow microreactor to test the catalytic activity, which the toluene (100 ppm) was delivered by 20% O2 in N2 with a total flow rate of 80ml min-1. From the catalytic results, pure Ce-BTC without Pt nanoparticles showed no activity, which indicated that organic links, Ce oxide secondary building unit, and their defective sites did not contribute to the catalytic reaction. As comparison, Pt@ Ce-BTC exhibited excellent activity, durability and reusability for oxidation of low concentration toluene, which  uggested that the exposing plane (111) of Pt nanoparticles played a primary role in toluene oxidation. In addition, Pt@Ce-BTC remained intact and maintained their crystal structure with catalytic deactivation after three runs. A facile in situ MOFs growth strategy was used to immobilize Pt nanoparticles within Ce-BTC framework matrix with high dispersion, which solved the aggregation problem. Furthermore, the functional Pt@Ce-BTC showed potential application in catalytic field as promising heterogeneous catalysts due to the excellent activity, durability and reusability.

Abstract

Cerium-containing catalyst exhibits excellent catalytic activity due to its special oxygen storage capacity, which makes the material exceptionally effective in catalytic applications. Metal organic frameworks (MOFs) has been a flourishing research theme and have provoked fascinated interest because of their versatile structures and interesting topologies. We report the study of cerium-containing catalysts derived from MOFs and their performance in toluene catalytic oxidation. Case 1: MnOx-CeO2 composite oxides. A series of MnOx-CeO2 oxides with various Mn content were prepared using CeBTC-MOF as sacrificial template towards catalytic oxidation of toluene. It was believed that MOFs-template method could prevent the aggregation of the particles and the uneven dispersion of the active constituent. Results showed that the composite oxides prepared by template method exhibited rod-shaped morphology, highly dispersed state, great specific surface area and nanocrystalline particles. In the process of incorporating Mn into MOF, Mn partly entered the lattice to form solid solution of Ce-Mn-O, while other Mn dispersed on the surface of CeO2. The state of the dispersed Mn included monolayer dispersion state and crystalline phase. Particularly, the strong interaction between CeO2 and dispersed Mn was the key factor affecting catalytic activity. Case 2: Pt@ Ce-BTC. Pre-stabilized Pt nanoparticles synthesized by alcohol reduction were immobilized within Ce-BTC matrix, using in situ one-step strategy. Analysis demonstrated the integral structure and excellent crystallinity of Pt@Ce-BTC with no Pt nanoparticles aggregation as well as good thermal stability. The obtained Pt@Ce-BTC exhibited attractive catalytic activity for toluene oxidation, that the temperature of toluene complete oxidation below 170oC. Furthermore, Pt@Ce-BTC had good catalytic durability due to the framework structure was remain unchanged and no Pt nanoparticles aggregation was observed after reaction.
