Abstract:
Heterogeneous catalytic systems based on the use of stimuli-responsive materials can be switched from an “on” active state to an “off” inactive state, which contributes to endowing the catalysts with unique functional properties, such as adaptability, recyclability and precise spatial and temporal control on different types of chemical reactions. All these properties constitute a step toward the development of nature-inspired catalytic systems. Even if this is a niche area in the field of catalysis, it is possible to find in literature intriguing examples of dynamic catalysts, whose systematic analysis and review are still lacking. The aim of this work is to examine the recent developments of stimuli-responsive heterogeneous catalytic systems from the viewpoint of different approaches that have been proposed to obtain a dynamic control of catalytic efficiency. Because of the variety of reactions and conditions, it is difficult to make a quantitative comparison between the efficiencies of the considered systems, but the analysis of the different strategies can inspire the preparation of new smart catalytic systems.

Abstract:
The purpose of this work is to study the possibilities of improving the quality of the processes of controlling the movement of the vessel along the course by combining individual standard controllers. Of the known scientific directions devoted to the problem being solved, the closest is the theory of systems with variable structure, in which, due to switching, a unique useful property is achieved, which are not possessed by individual switched structures. The article is devoted to the approach to the construction of the ship course control system, which is based on the principle of switching regulators during the transient process. This makes it possible to improve the quality of control processes in the system by using the features of individual regulators, in particular, the application of the switching principle made it possible to significantly increase the speed of the system in comparison with systems without switching and ensure the desired monotonic nature of the control process. The proposed approach is illustrated based on switchable P-controllers. The results of modeling the developed ship course control system are presented and discussed.

Abstract:
This work showcases the utility of switchable materials. Included are a switchable room-temperature ionic liquid, a switchable solvent, a switchable heterogeneous catalyst system, and a switchable gel. First, the switchable ionic liquid 2-butyl-1,1,3,3-tetramethylguanidium methylcarbonate is fully investigated. Its use in a complete chemical process (including reaction, separation, reformation, and recycle) is demonstrated with several reactions. Furthermore, its potential use for bitumen separation and purification and SO2 capture/isolation are discussed, and preliminary data is presented. Next, piperylene sulfone (PS), a switchable solvent, is synthesized and fully characterized. Anionic nucleophilic substitution reactions were performed in PS, the products were isolated in high yields, and then the PS was reformed for reuse. Then, we designed an immobilized fluorous microphase system that uses F-MonoPhos to induce high enantioselectivities as a switchable heterogeneous catalyst system. Finally, stable reversible polyethyleimine-CO2 gels have been synthesized with 1-octanol. Our findings indicate that PEI-1200/octanol/CO2 gels have potential as a possible drug carrier matrix for transdermal delivery applications.

Abstract:
Le travail de cette thèse de doctorat est axé sur le design, la synthèse et la caractérisation de systèmes moléculaires organiques et organométalliques luminescents dans le but de déclencher des processus de transfert photoinduit d’électron (PeT) ou d’énergie (EET) pour des applications dans les dispositifs optiques ou électroniques. Nous nous sommes d’abord intéressés aux molécules de type push-pull car elless’avèrent être des modèles intéressants pour l’étude du PeT. Nos systèmes sont construits autour de BτDIPY qui sert d’espaceur entre le donneur d’électron (julolidine ou triazatruxène) et l’accepteur d’électron (une unité dicyanovinyl). Les études en électrochimie et spectroscopie ont montrés un caractère à transfert de charge très prononcé. Entre autre nous avons synthétisé et étudié une série de ligands de type N^O (type base de Schiff) dérivés de la julolidine, une amine cyclique avec des propriétés électroniques très inattendues. Ces ligands, subissent des processus de transfert photoinduit de proton à l’état excité (ESIPT) et leurs spectres d’émission présentent une luminescence panchromatique. La compléxation desligands N^O au BF2 supprime l’ESIPT et augment les rendements quantiques de fluorescence. Les ligands derivés de la julolidine sont combinés avec d’autres unités chromophoriques i.e. Ir(III), Pt(II) afin de construire des systèmes multichromophoriques et stimuler des processus de EET entre les composants.Lors de ces travaux de thèse nous nous somme particulièrement intéressés aux systèmes moléculaires photocommutables dont l’unité centrale est un photochrome, le [1,3]oxazine. L’oxazine est combiné à un module moléculaire qui sert de donneur d’énergie et un module accepteur d’énergie choisie de façon optimale afin d’induire un transfert électronique d’énergie de manière contrôlé
The present doctoral thesis work deals with the design, synthesis and characterization of organic and organometallic luminescent molecular frameworks for triggering Photoinduced electron Transfer (PeT) and Electronic Energy Transfer (EET) processes for applications in optical andelectronic devices. First, we turned toward the organic push-pull chromophores because they are useful model systems for studying the mechanism of PeT process. We synthesized new push-pull systems bearing a dicyanovinyl fragment as the electron-acceptor and a strong electron-donorsuch as julolidine and triazatruxene covalently linked through a BODIPY dye bridge. Electrochemical and photophysical studies showed a pronounced charge transfer character within the new push-pull systems. Furthermore, we synthesized and studied a series of chelating N^O-type ligands (Schiff base-type), based on the strong electron-donating julolidine motif, displaying ESIPT process. Their luminescence profiles exhibited panchromatic luminescence band covering the whole visible spectrum. Complexation of N^O-site with boron difluoride fragment suppressed the ESPIT process and highly increased the fluorescence quantum yield. The N^O-chelating ligands were combined with Pt(II) chromophore, B(III) and Ir(III) such as to obtainmultichromophoric frameworks. According to the photophysical studies, EET processes were observed within the multichromophoric systems. We successfully obtained a new florescent switching triad constructed around a photochromic core, [1,3]oxazine, which bears an energy-donor and an energy-acceptor module such as to directly control the EET process

Abstract:
This research aims to develop solutions to relieve system stress conditions in electric grids. The approach adopted in this research is based on a new concept in the Smart Grid, namely, demand response optimization. A number of demand response programs with energy storage systems are designed to enable a community to achieve optimal demand side energy management. The proposed models aim to improve the utilization of the demand side energy through load management programs including peak shaving, load shifting, and valley lling. First, a model is proposed to nd the optimal capacity of the battery energy storage system (BESS) to be installed in a power system. This model also aims to design optimal switchable loads programs for a community. The penetration of the switchable loads versus the size of the BESS is investigated. Another model is developed to design an optimal load operation scheduling of a residential heating ventilation and air-conditioning system (HVACs). This model investigates the ability of HVACs to provide optimal demand response. The model also proposes a comfort/cost trade-os formulation for end users. A third model is proposed to incorporate the uncertainty of the photovoltaic power in a residential model. The model would nd the optimal utilization of the PV-output to supply the residential loads. In the first part of this research, mixed integer programming (MIP) formulations are proposed to obtain the optimal capacity of the (BESS) in a power system. Two optimization problems are investigated: (i) When the BESS is owned by a utility, the operation cost of generators and cost of battery will be minimized. Generator on/o states, dispatch level and battery power dispatch level will be determined for a 24-hour period. (ii) When the BESS is owned by a community for peak shaving, the objective function will have a penalty component for the deviation of the importing power from the scheduled power. MIP problems are formulated and solved by CPLEX.The simulation results present the effect of switchable load penetration level on battery sizing parameters. In the second part, a mixed integer programming (MIP) based operation is proposed in this part for residential HVACs. The objective is to minimize the total cost of the HVAC energy consumption under varying electricity prices. A simplied model of a space cooling system considering thermal dynamics is adopted. The optimization problems consider 24-hour operation of HVAC. Comfort/cost trade-o is modeled by introducing a binary variable. The big-M technique is adopted to obtain linear constraints while considering this binary variable. The MIP problems are solved by CPLEX. Simulation results demonstrate the effectiveness of HVAC's ability to respond to varying electricity price. Then, in the final part of this research, two Benders Decomposition strategies are applied to solve a stochastic mixed integer programming (MIP) formulation to obtain the optimal sizing of a photovoltaic system (PV) and battery energy storage system (BESS) to power a residential HVACs. The uncertainty of PV output is modeled using stochastic scenarios with the probability of their occurrence. Total cost including HVAC energy consumption cost and PV/battery installation cost is to be minimized with the system at grid-connected mode over eight hours subject to a varying electricity price. The optimization problem will nd the optimal battery energy capacity, power limit, a number of PV to be installed, and expected HVAC on/o states and BESS charging/discharging states for the next eight hours. This optimization problem is a large-scale MIP problem with expensive computing cost.

Abstract:
AbstractTemperature-dependent (nonlinear) transformation thermotics provides a powerful tool for designing multifunctional, switchable, or intelligent metamaterials in diffusion systems. However, its extension to multiphysics remains studied, in which the temperature dependence of intrinsic parameters is ubiquitous. Here, we theoretically establish a temperature-dependent transformation method for controlling multiphysics. Taking thermoelectric transport as a typical case, we prove the form invariance of its temperature-dependent governing equations and formulate the corresponding transformation rules. Our finite-element simulations demonstrate robust thermoelectric cloaking, concentrating, and rotating performance in temperature-dependent backgrounds. We further design two practical applications with temperature-dependent transformation: an ambient-responsive cloak-concentrator thermoelectric device that can switch between cloaking and concentrating; an improved thermoelectric cloak with nearly-thermostat performance inside. Our theoretical frameworks and application designs may provide guidance for efficiently controlling temperature-related multiphysics and enlighten subsequent intelligent multiphysical metamaterial research.

Abstract:
Polyvinyl alcohol (PVA) films with embedded electrically-responsive liquid crystal (LC) ellipsoids were fabricated to develop a membrane coating featuring tunable roughness. Membranes (∼30 microns thick) were placed between opposing pieces of indium-tin oxide (ITO) glass, creating electrodes for creation of a uniform electric field. Applied voltages ranged from 0V–350 V, as films were observed using an optical microscope. Thin-film interference patterns were observed in various regions of each film and were measured. Contour plots of film displacement were created and showed elevations across the observed region. The area of the first dark fringe regions, assumed to be in contact with the top glass surface, were measured as a function of applied voltage. The maximum displacement of the film was estimated to reach 1.5 microns and the area in contacted with the top glass surface increased 127% between 0–350 V. Finite element modelling results illustrate the influence of polarity on the roughness of the film surface.
