Abstract:
ABSTRACTOur objective is to design nanostructured hybrid inorganic-biological materials using the selfassembly of functionalized nanotubes and lipid molecules. In this presentation, we summarize the multiple control parameters which direct the equilibrium morphology of a specific class of nanostructured biomaterials. Individual lipid molecules are composed of a hydrophilic head group and two hydrophobic tails. A bare nanotube encompasses an ABA architecture, with a hydrophobic shaft (B) and two hydrophilic ends (A). We introduce hydrophilic hairs at one end of the tube to enable selective transport through the channel. The dimensions of the nanotube are set to minimize its hydrophobic mismatch with the lipid bilayer. We use a Molecular Dynamicsbased mesoscopic simulation technique called Dissipative Particle Dynamics which simultaneously resolves the structure and dynamics of the nanoscopic building blocks and the hybrid aggregate. The amphiphilic lipids and functionalized nanotubes self-assemble into a stable hybrid vesicle or a bicelle in the presence of a hydrophilic solvent. We demonstrate that the morphology of the hybrid structures is directed by factors such as the temperature, the molecular rigidity of the lipid molecules, and the concentration of the nanotubes. We present material characterization of the equilibrium morphology of the various hybrid nanostructures. A combination of the material characterization and the morphologies of the hybrid aggregates can be used to predict the structure and properties of other hybrid materials.

Abstract:
The research develops and tests new hybrid biomimetic materials that work as mechanically stimulating "scaffolds" to promote early regeneration in implanted bone healing phases. A biomimetic nanostructured osteoconductive material coated apparatus is presented. Bioinspired approaches to materials and templated growth of hybrid networks using self-assembled hybrid organic-inorganic interfaces is finalized to extend the use of hybrids in the medical field. Combined in vivo, in vitro and computer aided simulations have been carried out. A new experimental methodology for the identification of design criteria for new innovative prosthetic implant systems is presented. The new implant design minimizes the invasiveness of treatments while improving implant functional integration. A new bioactive ceramo-polymeric hybrid material was used to modify odontostomatological Titanium implants in order to promote early fixation, biomechanical stimulation for improved scaffold mineralization and ossification. It is a hybrid ceramo-polymeric nanocomposites based on Hydroxyl-Ethyl-Methacrylate polymer (pHEMA) filled with nanosilica particles that have shown biomimetic characteristics. This material swells in presence of aqueous physiological solution leading to the achievement of two biomechanical functions: prosthesis early fixation after and bone growth stimulation. Such multidisciplinary approach explores novel ideas in modelling, design and fabrication of new nanostructured biomaterials with enhanced functionality and improved interaction with OB cells

Abstract:
Nowadays, it has been challenging to develop novel techniques and synthesis processes for hybrid two-dimensional materials. Hence, this research presents an innovative technique for the fabrication of MoS2-Graphene (MoS2-Gr) hybrid nanostructured materials. The graphene was effectively generated in-situ and incorporated into the interlayer spacing of MoS2, which was synthesized by using a co-precipitation process with diethyl glycol as the solvent, followed by annealing the as-synthesized MoS2 at 800 oC for two hours in an inert atmosphere. The integrated graphene enhanced the width of MoS2 interlayers, exposing a substantial concentration of active edge sites in the hybrid material, according to SEM, XRD, HR-TEM, and other characterizations. This research might lead to the development of viable hybrid structured materials for various applications. In addition, this study outlines a novel advanced approach for creating hybrid 2D nanostructured materials with superior characteristics.

Abstract:
Over the past decade, lead halide perovskites have emerged as one of the leading photovoltaic materials due to their long carrier lifetimes, high absorption coefficients, high tolerance to defects, and facile processing methods. With a bandgap of ~1.6 eV, lead halide perovskite solar cells have achieved power conversion efficiencies in excess of 25%. Despite this, poor material stability along with lead contamination remains a significant barrier to commercialization. Recently, low-dimensional perovskites, where at least one of the structural dimensions is measured on the nanoscale, have demonstrated significantly higher stabilities, and although their power conversion efficiencies are slightly lower, these materials also open up the possibility of quantum-confinement effects such as carrier multiplication. Furthermore, both bulk perovskites and low-dimensional perovskites have been demonstrated to form hybrids with silicon nanocrystals, where numerous device architectures can be exploited to improve efficiency. In this review, we provide an overview of perovskite solar cells, and report the current progress in nanoscale perovskites, such as low-dimensional perovskites, perovskite quantum dots, and perovskite-nanocrystal hybrid solar cells.

Abstract:
Mesoporous nanostructured materials are useful for a widespread field of applications, such as gas storage; selective molecular adsorption; confined chemical reactions and catalysis. In this work, periodic mesoporous silica and organosilica materials, thanks to their high surface area, narrow pore size distribution and high regular structure, have been exploited to obtain nanostructured porous materials with different chemical nature, such as polymer or carbon. Periodic mesoporous silica objects with defined micrometric shape have been obtained by template synthesis in aqueous medium. A change in synthesis condition of temperature, time and acidity leads to the generation of different shapes such as gyroids, spheres and hollow tubes. Mesoporous silica particles have been exploited for confined polymerization of different monomers (styrene, methylmethacrylate and acrylonitrile) to obtain morphological polymeric nanocomposites. The nanocomposite with polyacrylonitrile has been then heated at high temperature in non-oxidative atmosphere to induce polymer carbonization until the formation of a graphitic-like carbon structure. The silica matrix has been then removed by chemical etching to obtain nanostructured porous materials in polymer and graphitic-like carbon with high surface area and the same micrometric morphology of starting silica matrix (shape replica effect). Afterwards, a periodic mesoporous organosilica system, with phenylene groups directly linked in the wall structure and organized on the molecular scale, has been synthesised, exploited as selective gas adsorption system and heated in non-oxidative atmosphere to obtain a new mesoporous carbon material with high surface area, very regular mesoporous structure and graphitic-like pore walls. Characterization of these materials has been conduced with X-ray diffraction, calorimetric techniques (DSC and TGA), adsorption of gases and vapours and advanced mono- and bi-dimensional NMR experiments to investigate the interaction between the organic and the inorganic moieties. Thermal evolutions of polyacrylonitrile and phenylene-organosilica have been studied with spectroscopic techniques of ATR and Raman, while the shape replica effect and the high regular pore structure have been directly seen with SEM and TEM microscopies.

Abstract:
The acid and base catalyzed simultaneous twin polymerization (STP) of various 2,2′-disubstituted 4H-1,3,2-benzodioxasiline derivatives 2a–d with 2,2′-spirobi[4H-1,3,2-benzodioxasiline] (1) are presented in this paper. The products are nanostructured ternary organic–inorganic hybrid materials consisting of a cross-linked organic polymer, silica and a disubstituted polysiloxane. It can be demonstrated whether and in which extent the copolymerization of the two inorganic fragments of 1 and 2 takes place among the STP and how the molar ratio of the two components determines the structure formation of the resulting hybrid material. Steric and electronic effects of the substituents at the silicon center of 2 on the molecular structure formation and the morphology of the resulting hybrid material were investigated by means of solid state CP MAS 29Si and 13C NMR spectroscopy as well as high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM). The mechanical properties (hardness and Young's modulus) of the hybrid materials were analyzed by means of nanoindentation measurements

Abstract:
Des matériaux hybrides de classe II ont été préparés à partir de précurseurs bis(tripropynylstannylés). Deux familles de précurseurs sol-gel incluant des espaceurs hydrocarbonés et thiophénique ont été obtenues et conduisent à des matériaux hybrides auto-organisés où les plans d’oxyde sont séparés par les espaceurs organiques. Ainsi l’espaceur rigide a donné lieu à une structure pseudo-lamellaire montrant une bande d’émission monomère avec un assez faible décalage vers le rouge par rapport à l'émission des précurseurs en solution. En revanche, alors que les xérogels thiényle plus désordonnés conduisent à une large émission caractéristique de la formation d’excimères ou de dimères. Par ailleurs, des films minces contenant les espaceurs alkylène et arylalkylène ont été préparés et ont montré une morphologie "pseudoparticulaire" poreuse et un ordre à courte distance contenant des réseaux SnOx. De façon inattendue, ces films minces hybrides détectent le dihydrogène dès une température de 50 °C dans la gamme 200-10000 ppm. A partir de ces films hybrides minces, le dioxyde d'étain cristallin (SnO2) a été préparé par un post-traitement thermique. Comme prévu, ces films SnO2 cassitérite détectent le dihydrogène et, dans une moindre mesure le monoxyde de carbone avec une température optimale de fonctionnement comprise entre 300 et 350 °C
Class II hybrid materials were prepared from ditin hexaalkynides. Two families of precursors, including either hydrocarbon or oligothiophene-based spacers, were obtained and led by the sol-gel process to self-assembled organotin-based hybrid materials made of planes of oxide separated by organic bridges. Thus, the rigid thienyl spacer gave rise to a “pseudo-lamellar” structure that showed a monomer emission band with a rather small red-shift compared with to the emission of the precursor in solution. However more disordered thienyl xerogels led to broad emission features assigned to excimer or dimer formation. Moreover, thin films containing alkylene- and arylalkylene bridged have been prepared and showed a “pseudoparticulate” porous morphology and a short-range hierarchical order in the organic-inorganic SnOx pseudoparticles. Unexpectedly these hybrid thin films detect hydrogen gas at a temperature as low as 50 °C at the 200-10000 ppm level. From these hybrid thin films, crystalline tin dioxide (SnO2) were prepared by a thermal post-treatment. As expected, cassiterite SnO2 films detected H2 and to a less extent CO with a best operating temperature comprised between 300 and 350 °C

Abstract:
The overall focus of this thesis is on the development and understanding of nanoporous layered silicates and membranes, particularly for potential applications in gas separations. Nanoporous layered materials are a rapidly growing area of interest, and include materials such as layered zeolites, porous layered oxides, layered aluminophosphates, and porous graphenes. They possess unique transport properties that may be advantageous for membrane and thin film applications. These materials also have very different chemistry from 3-D porous materials due to the existence of a large, chemically active, external surface area. This feature also necessitates the development of innovative strategies to process these materials into membranes and thin films with high performance.

Abstract:
The work presented in this dissertation suggests novel design of chemical plasmonic sensors which have been developed based on Localized Surface Plasmon Resonance (LSPR), and Surface-enhanced Raman scattering (SERS) phenomena. The goal of the study is to understand the SERS phenomena for 3D hybrid (organic/inorganic) templates and to design of the templates for trace-level detection of selected chemical analytes relevant to liquid explosives and hazardous chemicals. The key design criteria for the development of the SERS templates are utilizing selective polymeric nanocoatings within cylindrical nanopores for promoting selective adsorption of chemical analyte molecules, maximizing specific surface area, and optimizing concentration of hot spots with efficient light interaction inside nanochannels. The organic/inorganic hybrid templates are optimized through a comprehensive understanding of the LSPR properties of the gold nanoparticles, gold nanorods, interaction of light with highly porous alumina template, and the choice of physical and chemical attributes of the selective coating. Furthermore, novel method to assemble silver nanoparticles in 3D as the active SERS-active substrate has been demonstrated by uniform, in situ growth of silver nanoparticles from electroless deposited silver seeds excluding any adhesive polymer layer on template. This approach can be the optimal for SERS sensing applications because it is not necessary to separate the Raman bands of the polyelectrolyte binding layer from those of the desired analyte. The fabrication method is an efficient, simple and fast way to assemble nanoparticles into 3D nanostructures. Addressable Raman markers from silver nanowire crossbars with silver nanoparticles are also introduced and studied. Assembly of silver nanowire crossbar structure is achieved by simple, double-step capillary transfer lithography. The on/off SERS properties can be observed on silver nanowire crossbars with silver nanoparticles depending on the exact location and orientation of decorated silver nanoparticles nearby silver nanowire crossbars. As an alternative approach for the template-assisted nanostructure design, porous alumina membrane (PAM) can be utilized as a sacrificial template for the fabrication of the nanotube structure. The study seeks to investigate the design aspects of polymeric/inorganic hybrid nanotube structures with plasmonic properties, which can be dynamically tuned by external stimuli such as pH. This research suggests several different organic/inorganic nanostructure assemblies by various template-assisted techniques. The polymeric/inorganic hybrid nanostructures including SERS property, pH responsive characteristics, and large surface area will enable us to understand and design the novel chemical plasmonic sensors.

Abstract:
The size/shape dependent and unique physical and chemical properties presented by nanostructured materials have attracted great attention in several fields such as energy harvesting, optoelectronics and biomedicine, among others. Even though binary semiconductors have been some of the most studied systems until now, ternary and quaternary semiconductors have started to stand out due to the wide variety of compositions and, as a result, of properties they offer. The importance of hybrid nanomaterials is growing as well: the association of more than one material in the same nanostructure usually allows the preservation or even, the enhancement, of the different properties of the preliminary materials and combines them with the new ones originated from the interaction between the two domains. This thesis is focused on the design of novel compositionally controlled hybrid and ternary nanostructures based on low toxic materials. Firstly, a simple procedure at room temperature is reported for the synthesis of hybrid and ternary nanostructures of Ag-Au-Se and Ag-Au-S. The method consists in the reaction between pre-synthesised Ag2Se/Ag2S nanoparticles (NPs) and a Au(III) precursor. The reaction time, the concentration of gold solution, the surfactant nature and the Ag:Au ratio are the four key parameters that allow the control of the final product. Regarding the Ag-Au-Se system, Au-Ag2Se hybrid nanoparticles (HNPs), Au-Ag3AuSe2 HNPs and Ag3AuSe2 NPs were successfully synthesised. In addition, Au-Ag3AuSe2 HNPs were tested as thermoelectric material, obtaining an improved response in comparison with the binary material (Ag2Se). The potential of Ag3AuSe2 NPs as Computed Tomography contrast agents was also tested, obtaining promising results in this field. Concerning to the analogous system with sulphur, the higher miscibility of Au and S offers a more complex ternary diagram, with two ternary materials with different stoichiometries: Ag3AuS2 and AgAuS. A gradual transformation of Ag2S to Au2S was achievable by the proposed method, with the possibility of isolating Au-Ag2S HNPs, Au-Ag3AuS2 HNPs, Au-AgAuS HNPs, Au-Au2S HNPs and hollow Au2S NPs. Secondly, another ternary system was studied: Ag-Cu-S. Even though this system also presents two different ternary materials (Ag3CuS2 and AgCuS), the direct hot injection method proposed here only allows the formation of the AgCuS stoichiometry. Two different mechanisms are reported, depending on the precursor of copper used in the synthesis. The material was thermoelectrically characterized as well, but without showing a proper performance. Thirdly, four novel nanostructures based on Cu-Pt-Se are described. They were synthesised by a reaction at high temperature between pre-synthesised Cu2-xSe NPs and a Pt(II) precursor. The nanomaterials were thoroughly structurally and morphologically characterized to study the impact of the Pt:Cu ratio in the final product. The larger the amount of platinum in the structure, the more efficient diffusion of the element occurs through the Cu-Se lattice, with the consequent and slow spell of selenium until its totality. Finally, hybrophilic hybrid inorganic-organic nanocomposites formed by inorganic NPs (Au, Ag, Ag3AuSe2 i Au@Fe3O4) and a highly fluorescent low molecular weight Au(I) metallogelator are presented. Their coupling is mainly based on aurophilic/metallophilic interactions between atoms in the surface of the NPs and Au(I) atoms from the complex. Additionally, the Ag and Au nanocomposites were characterized by Raman Spectroscopy. It is well known that when a molecule is strongly coupled to a plasmonic nanoparticle, the intensity of the Raman peaks of the molecule are intensified. This phenomenon is known as Surface-Enhanced Raman Spectroscopy (SERS) and could be observed in both materials. In summary, in this thesis five hybrid and ternary nanostructured systems, based on low toxic materials, have been synthesised, characterized and studied, following the aim of investigate alternative materials, which, in a future, could be applied in energy conversion and biomedicine fields.
En els últims anys, els materials ternaris i híbrids han començat a sorgir gràcies al gran ventall de composicions i, per tant, de propietats que ofereixen i que els donen la possibilitat d’aplicar-se en diversos camps, com ara l’emmagatzematge d’energia, l’optoelectrònica o la biomedicina. Aquesta tesis està centrada en el disseny de noves nanoestructures ternàries i híbrides basades en materials amb una toxicitat baixa. En primer lloc, s’ha descrit un procediment simple a temperatura ambient per la síntesi de nanoestructures ternàries i híbrides d’Ag-Au-Se i d’Ag-Au-S que consisteix en la reacció entre nanopartícules d’Ag2Se i Ag2S sintetitzades prèviament i un precursor d’Au(III). El temps de reacció, la concentració del precursor d’or, la naturalesa del tensioactiu i la relació Ag:Au són els quatre paràmetres clau que permeten el control del producte final. Addicionalment, dos compostos del sistema Ag-Au-Se van ser caracteritzats termoelèctricament i com a agents de contrast en tomografia computada. En segon lloc, s’ha estudiat un altre sistema ternari, format per Ag-Cu-S. El mètode d’injecció en calent proposat en aquesta tesi permet la formació del material amb estequiometria AgCuS. El material va ser caracteritzat termoelèctricament, tot i que no mostra resultats satisfactoris degut a la seva baixa conductivitat elèctrica. En tercer lloc, es presenten quatre nanoestructures noves basades en Cu, Pt i Se, sintetitzades mitjançant una reacció a alta temperatura entre NPs de Cu2-xSe sintetitzades prèviament i un precursor de Pt(II). L’impacte de la relació Pt:Cu utilitzada en la síntesi en el producte final va ser estudiada. A mesura que la quantitat de platí augmenta en l’estructura, aquest es va introduint més eficientment en la xarxa cristal·lina del semiconductor de coure i seleni, expulsant gradual i lentament el seleni fins a la totalitat, augmentant així el caràcter metàl·lic de les nanoestructures finals. Finalment, es descriuen uns compostos híbrids hidrofílics, formats a partir de NPs inorgàniques (Au, Ag, Ag3AuSe2 i Au@Fe3O4) i un complex d’Au(I) de baix pes molecular i altament fluorescent. El seu acoblament està basat, essencialment, en interaccions aurofíliques/metal·lofíques entre els àtoms de la superfície de la nanopartícula i els àtoms d’Au(I) del complex.

Abstract:
Recently, technological advancement and the promise of next-generation devices have created an overwhelming push for the continued miniaturization of active systems to the micro- and nanometer scale. In this regime, traditional mechanical systems are largely inaccessible and as a result new active or stimuli-responsive materials are required. The work presented in this dissertation provides an understanding of the responsive nature of polymer and biopolymer interfaces especially in contact with metal nanoparticles. This understanding was utilized in conjunction with top-down template-based and self-assembly fabrication strategies to create hybrid protein based films and active polymer-metal hybrids that exhibit large and well-defined modulation of mechanical and optical properties. These materials processing developments represent advancement in the current state of the art specifically in three major areas: 1. template-based top-down control of protein chain conformation, 2. high-throughput synthesis and assembly of strongly coupled plasmonic nanoparticles with modulated optical properties (both near- and far-field), 3. field-assisted assembly of highly mobile and non-close packed magnetic nanorods with capabilities for rapid actuation.

Abstract:
The study of graphene has become one of the most exhilarating topics in both academia and industry for being highly promising in various applications. Because of its excellent mechanical, electrical, thermal and nontoxic properties, graphene has shown promising application in energy storage devices such as lithium-ion-battery (LIB), super capacitor and solar cell. In lithium ion battery, graphite is the most commonly used material as anode. However, due to the limited specific surface area of graphite materials, the diffusion of the Li ions in the anode graphite is relatively slow, leading to limited energy storage density. In order to further increase the capacity, nano-structured materials have been extensively studied due to its potential in reducing Li-ion diffusion pathway. To date, one of the most promising approaches to improve the Li-ion diffusion rate is to introduce hybrid nanostructured electrodes that connect the nonconductive high surface area nanowire with nanostructured carbon materials. While there have been several research efforts investigated to fabricate nanowire-graphene hybrids, all the them were focused on randomly distributed nanostructures thus the LIB performance enhancement was limited. Therefore, this paper will introduce a novel hybrid structure with vertically aligned nanowire on graphene aerogel aiming to further increase the performance of LIB. The aligned nanowire array provides a higher specific surface area and could lead to high electrodeelectrolyte contact area and fast lithium ion diffusion rate. While the graphene aerogel structure is electrically conductive and mechanically robust, as well as has low specific density. The developed nanowire/graphene hybrid structure could have the potential to enhance the specific capacity and charge-discharge rate. Scanning Electron Microscopy (SEM) and X-Ray Diffraction (XRD) measurements were used for the initial characterization of this nanowire/graphene aerogel hybrid material system.

Abstract:
Abstract In previous studies, it has been demonstrated that nanostructured Al2O3-13wt%TiO2 coatings deposited via air plasma spray (APS) exhibit higher wear resistance when compared to that of conventional coatings. This study aimed to verify if HVOF-sprayed Al2O3-13wt%TiO2 coatings produced using hybrid (nano+submicron) powders could improve even further the already recognized good wear properties of the APS nanostructured coatings. According to the abrasion test results (ASTM G 64), there was an improvement in wear performance by a factor of 8 for the HVOF-sprayed hybrid coating as compared to the best performing APS conventional coating. When comparing both hybrid and conventional HVOF-sprayed coatings, there was an improvement in wear performance by a factor of 4 when using the hybrid material. The results show a significant anti-wear improvement provided by the hybrid material. Scanning electron microscopy (SEM) at low/high magnifications showed the distinctive microstructure of the HVOF-sprayed hybrid coating, which helps to explain its excellent wear performance.

Abstract:
Chemically synthesized nanostructures such as nanowires1, carbon nanotubes2 and quantum dots3 possess extraordinary physical, electronic and optical properties that are not found in bulk matter. These characteristics make them attractive candidates for building subsequent generations of novel and superior devices that will find application in areas such as electronics, photonics, energy and biotechnology. In order to realize the full potential of these nanoscale materials, manufacturing techniques that combine the advantages of top-down lithography with bottom-up programmed assembly need to be developed, so that nanostructures can be organized into higher-level devices and systems in a rational manner. However, it is essential that nanostructure assembly occur only at specified locations of the substrate and nowhere else, since otherwise undesirable structures and devices will result. Towards this end, we have developed a hybrid micro/nanoscale-manufacturing paradigm that can be used to program the assembly of nanostructured building blocks at specific, pre-defined locations of a chip in a highly parallel fashion. As a prototype system we have used synthetic DNA molecules and gold nanoparticles modified with complementary DNA strands as the building blocks to demonstrate the highly selective and specific assembly of these nanomaterials on lithographically patterned substrates.

Abstract:
The fabrication of arbitrary nanostructured devices in 3D space is relevant to many areas of academic and industrial research. From hybrid systems with various physical features to complex 3D optical interconnects, the added functionality gained by 3D nanomanufacturing is promising for the development of novel applications. Nevertheless, the 2D nature of conventional nanomanufacturing processes (i.e. lithography) underutilizes the 3rd dimension since there is currently no infrastructure for 3D. Nanostructured Origami has been proposed [1-3] as one solution to the 3D nanomanufacturing problem. The two-step process consists of first patterning devices and creases (axes of rotation) in 2D followed by a subsequent folding step which actuates the origamis to its final 3D shape. Several actuation mechanisms have been investigated for the folding step, and the folding of simple origamis with an open kinematic chain has been successfully demonstrated experimentally [1-3]. Since the origami segments must be accurately aligned in the 3D folded state, the actuation mechanisms for Nanostructured Origami must be both controllable and repeatable. By developing analytical models of the origamis, control schemes can be simulated to aid in the manufacturing of devices in the laboratory. As an example, a PD control scheme is introduced to achieve set-point position control of an example origami, the corner cube. In the laboratory, a PD control system would be built using a magnetic feedback mechanism. A strip of gold is patterned as a hinge material, and electrical current passes through the wire. In the presence of a magnetic field, the Lorentz force acts upon the origami segments and the resulting torque is given by τ = Cicos α,[Equation] where C is a positive constant, i is the current, and α is the angle between the magnetic field and the current. The PD control law for Nanostructured Origami is equivalent to PD control of an articulated robotic manipulator, with the exception that gravity can be ignored due to the low masses of the membranes. Instead, the stiffnesses of the hinges must be balanced, resulting in a control torque of [Equation] where τ is the vector of joint torques, G is the constraint Jacobian, Kp is the proportional control constant, Kd is the derivative control constant, K is the hinge stiffness matrix, q is the vector of joint angles, and qd is the desired steady-state values of the joint angles. This input torque is applied to the origami device, and the response is calculated by integrating the system's equations of motion [3]. The angular response of the PD controller for the corner cube origami is plotted in Fig. 1, and Fig. 2 shows a schematic of the folding of the corner cube from flat to folded state. Note the well-behaved response for a Kp value of 1500, which demonstrates zero overshoot and a rise time of approximately 15 milliseconds. A plot of the joint torques as a function of time is shown in Fig. 3. This abstract has briefly introduced the use of a PD controller for the actuation of origami devices. For a Lorentz force actuation scheme, we have demonstrated through simulations that the PD control law is stable and robust. If complicated 3D origamis with multiple closed kinematic chains are to be built, detailed control laws must be implemented. Advanced control techniques, such as optimal control, will be investigated to explore improved actuation strategies.

Abstract:
Abstract Ba(Mg1/3Ta2/3)O3 (BMT), a high melting point refractory oxide, is envisioned as a thermal barrier coating material. In this study, six chemical reagents combinations are investigated as BMT coating precursors: one BMT powder suspension and five Ta2O5 suspensions in nitrate solutions or acetate solutions. A hybrid suspension / sol plasma spray process is designed to axially inject these precursors into a RF thermal plasma torch to synthesize BMT and to deposit nanostructured coatings. X-ray photoelectron spectroscopy (XPS) was used to evaluate the element evaporation during plasma spraying. Thermogravimetric analysis and differential thermal analysis (TG/DTA) are applied to investigate the BMT formation. Parameters such as precursor chemistry and proportion, plasma power, spray distance and substrate preheating are studied with regards to the coating phase structure. The results indicate that the combination of twice the Mg stoichiometric amount with a power of 50 kW shows the best results when using nanocrystalline Ta2O5 as Ta precursor. When choosing nitrates as Ba and Mg precursors, predominant crystalized BMT can be obtained at lower plasma power (45 kW) when compared to acetates (50 kW). BaTa2O6, Ba3Ta5O15, Ba4Ta2O9, Mg4Ta2O9 are the main secondary phases during BMT preparation process. Because of the complicated acetate decomposition, the coating deposition rate from nitrate precursors is higher than that from acetate ones.
