Soudani, Allaoua. "Conception et développement d’un processus innovant pour l’intensification des transferts de chaleur et de masse dans un adsorbeur de machine frigorifique à adsorption et intégration des prototypes expérimentaux dans une plateforme d'émulation de la Grande Région." Electronic Thesis or Diss., Université de Lorraine, 2022. http://www.theses.fr/2022LORR0001.
The climate change we are witnessing is forcing us to rethink our energy production units. By 2050 the world's need for cooling will consume 37% of the world's electricity production and add more than 2 billion tonnes of CO₂ per year to the atmosphere. Adsorption refrigeration machines are an alternative with great potential but the adsorption technology is still poorly understood. This thesis provides a new approach to the frequency analysis of heat and mass transfer dynamics within the material of an adsorber and lays the foundation for the construction of a numerical model of the adsorption phenomenon in a silica gel grain. The construction of a prototype bench for the testing of future adsorbers has made it possible to identify the complex problems in the coupling between adsorbers, evaporators and condensers. The integration by emulation of a prototype machine in the RCC|Kn large area network has contributed to deepen the future global numerical model in all its dimensions. The interconnection of the platforms of the large region has laid the first important milestones of the RCC|Kn network. The test of more than 60 hours has shown a high stability in both hardware and software infrastructures. This new network opens up new perspectives in various fields such as data analysis, machine learning, data centres, digital twins or the integration of external data streams
Hamou, Mohamed. "Evaluation of the reverse flow reactor concept for the homogeneous molecular catalysis and case study of methyl oleate metathesis." Thesis, Lyon, 2016. http://www.theses.fr/2016LYSE1122.
The reverse flow reactor for heat trapping is an efficient technology that integrates the chemical reaction and the recovery of the heat of the reaction. This technology was widely commercialized and applied in industry because of the reactor productivity enhancement and the process intensification it offers. By heat-matter analogy, we wanted, in this thesis, to evaluate the reverse flow technique and the combination of the chemical reaction with the trapping and the recycling of the catalyst (matter) in one single multi-functional adsorber reactor. The metathesis of olefins that uses molecular catalysts -which are imperfectly immobilized and heterogeneized on the solid support- can be performed in the reverse flow adsorber reactor that claims to separate, recycle and trap the catalyst. The targeted reaction is the self-metathesis of methyl oleate. Thus, a kinetic model of the reaction was developed using a micro-kinetic approach. The obtained kinetic model was fitted to the experiences to get the kinetic parameters values. Then, the kinetic model can be integrated in the reverse flow adsorber reactor model to predict the conversion and the outlet methyl oleate concentration. The reverse flow reactor adsorber was evaluated and studied (by modeling and theoretical study) to have a better understanding of its behavior, and of the operating parameters influence on the process (catalyst leaching, conversion, productivity, etc.). A single fixed bed adsorption column is proposed as a design for the reverse flow adsorber reactor. The simulation results show the process intensification that offers the reverse flow adsorber reactor for catalyst trapping in comparison with a conventional continuous reactor (continuous flow tubular reactor). They also show that it is not possible to reach a stable operation and a permanent regime without catalyst makeup that compensate the leaching. Then, an experimental setup was built to verify, to validate the simulations results, and to demonstrate, at the pilot scale, the feasibility of the reverse flow technology to separate and to trap the adsorbate inside the adsorber. And similarly to the reverse flow reactor for heat trapping, the reverse flow adsorber reactor for catalyst trapping and separation can have an asymptotic behavior under certain operating conditions, and approaches the operation of a counter current adsorber reactor. By modeling and numerical calculation, it has been determined the operating conditions, at which, the reverse flow and the counter current adsorber reactors are equivalents. The counter current asymptotic model allow a rapid reverse flow reactor computing and pre-design

As a first exercise, a test system of xanthate adsorption onto lead sulphide minerals was studied. A survey of possible calibration standards (pure xanthate, a synthetic lead-xanthate, galena (PbS) and a lead sulphide ore conditioned with xanthate) resulted in linear curves for all four cases. The quantification of isopropyl xanthate adsorption onto batch flotation products (concentrate and tail) was used to determine that ore standards gave the most accurate results.
The technique was also tested for quantification of adsorbed amines. Two collectors, dodecylamine and diphenylguanidine, and a depressant, triethylenetetramine, were studied. A common calibration curve was prepared using diphenylguanidine adsorbed on Inco matte. Results show that the HAGIS technique can easily be used to quantify adsorbed amines.
It is concluded that the HAGIS technique is a powerful new tool for the quantitative determination of adsorbed reagents. The xanthate study showed the use of ores as standards produces the best calibration. The amine study introduced the possibility of analyzing reagent mixtures.

López-Aranguren, Oliver Pedro. "Functionalized adsorbent materials using supercritical CO2." Doctoral thesis, Universitat Autònoma de Barcelona, 2014. http://hdl.handle.net/10803/284975.
Historically, porous silica (SiO2) is one of the most used adsorbents for a wide variety of processes in the industry. However, the fast grown on the demand of new nanotechnology based materials and sustainable green processes have made necessary the development of adsorbents with improved physico-chemical properties. One of the most applied options to modify porous silica is the incorporation on the surface of organic functional molecules, giving place to hybrid materials, in which the properties of both components are combined. In this doctoral thesis, supercritical carbon dioxide (scCO2) has been used as the solvent to carry out the functionalization processes. Carbon dioxide is a sustainable solvent and its use has been preferred in front of toxic organic liquid solvents, often applied in the traditional methods of synthesis. Amorphous silica matrices with structural ordered pores (MCM-41, 4 nm) and disordered pores (silica gel, 4-9 nm) were selected for the functionalization processes. Besides, the properties conferred by functionalization to microporous crystaline zeolites have been preliminary studied. The modifying agents applied in this thesis were either alkyl (octyltriethoxysialane) or amino (methylaminopropyltrimethoxisilane) silane and aziridine. The later compound is a monomer which polymerizes in presence of CO2, leading to hyperbranched polyethyleneimine (PEI) with multiple amino groups formed into the silica pores. This novel method only requires compressed CO2 as the reagent and the catalyst of the polymerization reaction of aziridine, which usually requires the use of organic solvents, a solid catalyst, high temperatures and long processing times. The functionalization of porous silica with aminosilane in scCO2 is more complex than the case of alkysilanes due to the high reactivity between amino groups and CO2 to form unsoluble carabamate species. However, in this study a protocol was designed to partially inhibit carabamate formation by controlling the pressure and temperature of the reaction media. The obtained materials were characterized using solid state characterization tools: low temperature N2 and CO2 adsorption, thermal analysis, infrared spectroscopy and X-Ray diffraction. Moreover, modeling and simulation methods were used as complementary tools that allowed the study of this complex systems with a high level of detail. The alkyl chain of the alkylsilane induced to the porous system a hydrophobic behavior, hence, obtaining materials candidates for oil adsorption. The functionalization with organic molecules containing the amino group allowed the preparation of materials for the adsorption and separation of CO2 from diluted gases (CO2 sequestration). The CO2 adsorption properties of the synthesized aminosilicas were evaluated combining experimental adsorption tools with molecular simulations. The characterization of these materials was based on the evaluation of the overall CO2 adsorption capacity and the influence of the temperature, the selectivity of the CO2 adsorption in gas mixtures, the stability in the cyclic adsorption/desorption process and the kinetics, which were determined by performing both microbalance and CO2 adsorption isotherms at different temperatures.

We first reported the selective detection of single nitric oxide (NO) molecules using a specific DNA sequence of d(AT) 15 oligonucleotides, adsorbed to an array of near infrared fluorescent semiconducting single-walled carbon nanotubes (AT₁₅-SWCNT). While SWNT suspended with eight other variant DNA sequences show fluorescence quenching or enhancement from analytes such as dopamine, NADH, L-ascorbic acid, and riboflavin, d(AT)₁₅ imparts SWNT with a distinct selectivity toward NO. In contrast, the electrostatically neutral polyvinyl alcohol, enables no response to nitric oxide, but exhibits fluorescent enhancement to other molecules in the tested library. For AT₁₅ - SWCNT, a stepwise fluorescence decrease is observed when the nanotubes are exposed to NO, reporting the dynamics of single-molecule NO adsorption via SWCNT exciton quenching. We describe these quenching traces using a birth-and-death Markov model, and the maximum likelihood estimator of adsorption and desorption rates of NO is derived. Applying the method to simulated traces indicates that the resulting error in estimation is less than 5% under our experimental conditions, allowing for calibration using a series of NO concentrations. As expected, the adsorption rate is found to be linearly proportional to NO concentration, and the intrinsic single-SWCNT-site NO adsorption rate constant is 0.001 s-¹ [mu]M NO-¹. The ability to detect nitric oxide quantitatively at the single-molecule level may find applications in new cellular assays for the study of nitric oxide carcinogenesis and chemical signaling, as well as medical diagnostics for inflammation. Further, we also explored the concept of creating molecular recognition sites using polymer-SWCNT complexes. Molecular recognition is central to the design of therapeutics, chemical catalysis and sensor platforms, with the most common mechanisms involving biological structures such as antibodies[l] and aptamers[2, 3]. The key to this molecular recognition is a folded and constrained heteropolymer pinned, via intra-molecular forces, into a unique three-dimensional orientation that creates a binding pocket or interface to recognize a specific molecule. An alternate approach to constraining a polymer in three-dimensional space involves adsorbing it onto a cylindrical nanotube surface[4-7]. To date, however, the molecular recognition potential of these structured, nanotube-associated complexes has been unexplored. In this work, we demonstrate three distinct examples in which synthetic polymers create unique and highly selective molecular recognition sites once adsorbed onto a single-walled carbon nanotube (SWCNT) surface. The phenomenon is shown to be generic, with new recognition complexes demonstrated for riboflavin, L-thyroxine, and estradiol, predicted using a 2D thermodynamic model of surface interactions. The dissociation constants are continuously tunable by perturbing the chemical structure of the heteropolymer. The complexes can be used as new types of sensors based on modulation of SWCNT photoemission, as demonstrated using a complex for real time spatio-temporal detection of riboflavin in murine macrophages. Cardiac biomarkers troponin I and T are recognized as standard indicators for acute myocardial infarction (AMI, or heart attack), a condition that comprises 10% of U.S. emergency room visits [8]. There is significant interest in a rapid, point-of-cae (POC) device for troponin detection[9]. In this work we demonstrate a rapid, quantitative, and label-free assay specific for cardiac troponin T detection, using fluorescent single-walled carbon nanotubes (SWCNTs). Chitosan-wrapped carbon nanotubes are crosslinked to form a thin gel that is further functionalized with nitrilotriacetic acid (NTA) moieties. Upon chelation of Ni²+, the Ni²+ -NTA group binds to a hexa-histidine-modified troponin antibody, which specifically recognizes the target protein, troponin T. As the troponin T binds to the antibody, the local environment of the sensor changes, allowing for the detection through changes in SWCNT bandgap fluorescence intensity. In this work, we have developed the first near-infrared SWCNT sensor array for specific cTnT detection. Detection can be completed within 3 minutes, and the sensor responds linearly to the cTnT concentrations, with the experimental detection limit of 100 ng/ml (2.5 nM). This platform may provide a promising new tool for POC AMI detection in the future. Moreover, the work presented two useful methods of characterizing two commonly used functional groups, amines and carboxylic acids in soft gels, and this will be useful for other researchers studying hydrogel chemistry. In addition, we synthesized and characterized chitosan-gels both with and without NTA groups, and we compared fluorescence responses upon the addition of four different divalent cations, including Ni²+ , CO², Mg²+, and Mn²+. We proposed a model based Flory-Huggins theory, without any fitted parameters, that is able to describe the fluorescence increase as the Ni²+ concentration increases. The model suggests that the strong binding of Ni²+ onto NTA groups decreases the number of mobile ions in the gel, resulting in a reduction in the ionic chemical potential inside the gel. As a result, the gel de-swells, leading to a local SWCNT concentration increase and an increase in the SWCNT fluorescence signal.

The aim of this project is to create a deeper understanding of biochar’s ability to adsorbnutrients. In the long run the aim is to find a way to use the most suitable structures of biocharfor a maximum adsorption of different kinds of nutrients. The objective of this project is tofind, through case studies and practical experiments, an effective method to examine andanalyze the structure of biochars and their ability to adsorb nitrates and phosphates. The conclusion of the project was that analysis of the biochar’s ability to adsorb is a complexmatter. The BET-analysis is a good method to find the structure of the biochar. However, iodinenumber analysis could be a better alternative to directly find a value on the biochar’s ability toadsorb. The ICP-analysis of the solutions only works for phosphor, therefore spectroscopywould be a better alternative since it also can detect nitrogen and the different compounds.

L'inquinamento ambientale è cresciuto fino a diventare un problema che colpisce l'aria, l'acqua, il suolo e gli ecosistemi, principalmente a causa della crescita della popolazione mondiale in combinazione con un rapido sviluppo economico, che ha portato a un massiccio aumento della produzione globale. In effetti, è legato all'aumento dell'utilizzo e della complessità delle sostanze chimiche in molte attività umane. In particolare, l'ambiente acquatico globale è stato influenzato da sostanze chimiche antropogeniche ampiamente diffuse e, tra queste, i contaminanti di interesse emergente (CEC), compresi i prodotti farmaceutici e i prodotti per la cura personale, sono di particolare rilevanza poiché possono avere un impatto sulla vita acquatica e salute umana. CEC è un termine usato per descrivere sostanze chimiche sintetiche o presenti in natura o qualsiasi microorganismo che non è comunemente monitorato nell'ambiente ma ha il potenziale di entrare nell'ambiente e causare effetti negativi noti o sospetti. I principali gruppi di CEC sono prodotti farmaceutici, prodotti per la cura personale, interferenti endocrini, tensioattivi, contaminanti organici persistenti, additivi industriali e dolcificanti artificiali. Questi contaminanti sono difficili da rintracciare a causa della necessità di metodi di rilevamento specifici, sollevando la domanda su quanto tempo questi contaminanti siano prevalenti ell'ecosistema e come il processo di contaminazione possa essere invertito o ridotto. Inoltre, è improbabile che diversi CEC vengano rimossi dai processi convenzionali di trattamento delle acque reflue (WWT). Le tecnologie avanzate di trattamento delle acque reflue sono state identificate per essere efficaci nel trattamento delle acque contaminate, come la nanofiltrazione, l'osmosi inversa,l'ozonizzazione e l'ossidazione chimica. Tra le diverse soluzioni, l'adsorbimento, una tecnologia consolidata, è ancora considerata un metodo affidabile e robusto per purificare soluzioni acquose a basso costo e con alta efficienza. Uno dei principali vantaggi delle tecnologie basate sull'adsorbimento è che sono in grado di rimuovere i contaminanti in intervalli di concentrazione molto bassi, una condizione operativa in cui la maggior parte delle altre tecniche di separazione sono scarsamente efficienti a causa dei piccoli gradienti di concentrazione coinvolti. Inoltre, l'adsorbimento è un metodo versatile che può rimuovere contemporaneamente molti diversi composti organici e inorganici, a condizione che venga impiegata una miscela adatta di materiali adsorbenti.Questa tesi si è concentrata sulla valutazione di diverse strategie per rimuovere gli inquinanti dalla matrice acquosa. In particolare, abbiamo studiato metodi basati sull'adsorbimento, e in questo caso sono stati selezionati materiali adsorbenti diversi tra loro per struttura, composizione chimica e condizioni operative, che possono essere suddivisi in due classi: (i) adsorbente microporoso silico alluminato (zeoliti) e (ii) membrane a matrice mista a base di carbonio (MMM). In questa tesi sono state studiate le proprietà adsorbenti delle zeoliti verso diverse classi di CEC (farmaci, PFAS e contaminanti organici) in soluzioni acquose al fine di studiare l'efficienza di questi materiali silicei in due applicazioni, ovvero: (1) la rimozione di contaminanti da matrice acquosa, (2) la fase di pre-concentrazione per l'analisi dei microinquinanti. Inoltre, sono state studiate anche le proprietà di adsorbimento MMM verso i composti perfluorurati. Le MMM sono composti da una fase polimerica continua e da una carica inorganica dispersa. Questa tesi include uno studio sui processi di ossidazione avanzati per la degradazione di prodotti farmaceutici in ambiente acquoso. In particolare sono stati studiati due diversi fotocatalizzatori: (i) decatungstato di sodio e (ii) triossido di tungsteno, questi semiconduttori hanno la capacità comune di fotoprodurre radicali .OH in soluzioni acquose.

This Thesis is devoted to model the adsorption of Polyoxometalates (POMs) on metallic surfaces. From the structural determination of these composite materials, we propose different models in which the combination of both quantum and classical methodologies, we intent to describe the adsorption of [α-SiW12O40]4- on silver surfaces. Adsorption mode and structural parameters are successfully reproduced, and the spectroscopic data as well. In order to correctly describe the electronic structure, it is compulsory to include explicit water molecules (water) and counterions (K+ and Cs+) in the model. After including the environment, it is possible to reproduce the spontaneous reduction of the POM. Using this strategy a comparative study of metal and charge effects in the adsorption is done. For high charged systems becomes necessary to finally optimise the structure considering the environment for a better description of the adsorption. The latest part of the Thesis is dedicated to the adsorption on gold nanoparticles.

This thesis contains two parts. The first part concerns the research work on free molecules using synchrotron-radiation-related techniques. Auger electron spectra of two free open-shell molecules, O2 and NO, were studied experimentally and theoretically. Photoionization experimental technique with tunable synchrotron radiation source was used to induce core-level electron ionization and obtain the KVV normal Auger electron spectra. A quantitative assignment of O2 normal Auger spectrum was obtained by applying ab initio CI calculations and LVI Auger line shape simulations including the bond length dependence of Auger transition rates. The photon energy dependence of normal Auger electron spectra was focused on with photon energies in the vicinities of core-ionization threshold energies. Consequently, the MAPCI (Molecular Auger Post Collision Interaction) theory was developed. Taking the near-threshold O2 normal Auger spectrum as an example, the two extreme cases of MAPCI effect, “atomic-like PCI” and “molecular PCI”, were discovered and discussed. The effect of shape resonance on near-threshold molecular normal Auger spectrum was discussed taking NO near threshold normal Auger spectra as example.
The second part deals with research work on the chemisorption of small epoxy organic molecules, ethylene oxide, methyl oxirane, on Si (100) surfaces. Synchrotron radiation related techniques, UPS, XPS and NEXAFS, were applied. Based on the valence photoemission spectra, C 1s and Si 2p XPS spectra, the epoxy ring opening reactions of these molecules in chemisorption process were proved. Further tentative search for the surface-adsorbate CDAD effect was performed, and no evident circular dichroism was confirmed.
Kraikivski, Pavel. "Non-equilibrium dynamics of adsorbed polymers and filaments." Phd thesis, Universität Potsdam, 2005. http://opus.kobv.de/ubp/volltexte/2005/597/.
The first part is dedicated to thermally activated dynamics of polymers on structured substrates in the presence or absence of a driving force. The structured substrate is represented by double-well or periodic potentials. We consider both homogeneous and point driving forces. Point-like driving forces can be realized in single molecule manipulation by atomic force microscopy tips. Uniform driving forces can be generated by hydrodynamic flow or by electric fields for charged polymers.
In the second part, we consider collective filament motion in motility assays for motor proteins, where filaments glide over a motor-coated substrate. The model for the simulation of the filament dynamics contains interactive deformable filaments that move under the influence of forces from molecular motors and thermal noise. Motor tails are attached to the substrate and modeled as flexible polymers (entropic springs), motor heads perform a directed walk with a given force-velocity relation. We study the collective filament dynamics and pattern formation as a function of the motor and filament density, the force-velocity characteristics, the detachment rate of motor proteins and the filament interaction. In particular, the formation and statistics of filament patterns such as nematic ordering due to motor activity or clusters due to blocking effects are investigated. Our results are experimentally accessible and possible experimental realizations are discussed.
In der vorliegenden Arbeit behandeln wir zwei Probleme aus dem Gebiet der Nichtgleichgewichtsdynamik von Polymeren oder biologischen Filamenten, die an zweidimensionale Substrate adsorbieren.
Der erste Teil befasst sich mit der thermisch aktivierten Dynamik von Polymeren auf strukturierten Substraten in An- oder Abwesenheit einer treibenden Kraft. Das strukturierte Substrat wird durch Doppelmulden- oder periodische Potentiale dargestellt. Wir betrachten sowohl homogene treibende Kräfte als auch Punktkräfte. Punktkräfte können bei der Manipulation einzelner Moleküle mit die Spitze eines Rasterkraftmikroskops realisiert werden. Homogene Kräfte können durch einen hydrodynamischen Fluss oder ein elektrisches Feld im Falle geladener Polymere erzeugt werden.
Im zweiten Teil betrachten wir die kollektive Bewegung von Filamenten in Motility-Assays, in denen Filamente über ein mit molekularen Motoren überzogenes Substrat gleiten. Das Modell zur Simulation der Filamentdynamik beinhaltet wechselwirkende, deformierbare Filamente, die sich unter dem Einfluss von Kräften, die durch molekulare Motoren erzeugt werden, sowie thermischem Rauschen bewegen. Die Schaftdomänen der Motoren sind am Substrat angeheftet und werden als flexible Polymere (entropische Federn) modelliert. Die Kopfregionen der Motoren vollführen eine gerichtete Schrittbewegung mit einer gegebenen Kraft-Geschwindigkeitsbeziehung. Wir untersuchen die kollektive Filamentdynamik und die Ausbildung von Mustern als Funktion der Motor- und der Filamentdichte, der Kraft-Geschwindigkeitscharakteristik, der Ablöserate der Motorproteine und der Filamentwechselwirkung. Insbesondere wird die Bildung und die Statistik der Filamentmuster, wie etwa die nematische Anordnung aufgrund der Motoraktivität oder die Clusterbildung aufgrund von Blockadeeffekten, untersucht. Unsere Ergebnisse sind experimentell zugänglich und mögliche experimentelle Realisierungen werden diskutiert.
