Abstract:
Metal–organic frameworks (MOF) are a new type of porous materials that have great potential for adsorption of voltaic organic compounds (VOCs). These types of materials composed of metal ions and organic ligands are easy to synthesize, have high surface areas, their surface chemistry can be adjusted to the desired application, and they can also have good chemical and thermal stability. Therefore, this work focuses on the synthesis of a highly hydrophobic MOF material called CIM-80, a porous material that is made up of the Al3+ cation and the mesaconate linker. This MOF has a B.E.T. of approximately 800 m2/g and has potential applications for the adsorption of hydrophobic organic compounds. However, its synthesis is expensive and very dirty. Therefore, we have studied the synthesis conditions necessary to achieve high synthesis yields (85%) and materials with high crystallinity and accessible porosity. To achieve these results, we have used urea as a mild deprotonation reagent and modulator as an alternative to NaOH, which is traditionally used for the synthesis of this MOF. Once the synthesis of this material was controlled, its adsorption/desorption behavior of water and organic compounds such as toluene, cyclohexane and m-xylene was studied by means of vapor adsorption isotherms. The results show the hydrophobic character of the material and the greater affinity the material has toward aliphatic compounds than toward aromatic ones, with toluene being the most adsorbed compound, followed by cyclohexane and m-xylene.

Abstract:
Herein, we present a simple and inexpensive method for the immobilization of Metal–Organic Framework (MOF) particles in the form of pellets and membranes. This processing procedure is possible using polymethacrylate polymer (PMMA) as a binding or coating agent, improving stability and significantly increasing the water repellency. HKUST and MMOF-74 (M = Mg2+, Zn2+, Co2+ or Ni2+) are stable with the processing and high loadings of MOF materials into the processed pellet or membranes. These methods can provide the know-how for the immobilization of MOFs for, for example, application in air purification and the removal of toxic compounds and are well-suited for deployment in air purification devices.

Abstract:
Metal-organic frameworks (MOFs) are versatile materials that incorporate metal centers along with organic linkers in highly ordered, intricate structures. MIL-53 is a MOF that exhibits a “breathing effect,” where the pore size and MOF topology are profoundly influenced by the identity and binding mechanism of guest molecules. This phenomenon renders MIL-53 a promising candidate for sensing applications. In this report, the adsorption of various organic compounds within MIL-53 is investigated using a combination of complementary techniques. Thermal gravimetric analysis experiments confirm loading of the guest molecules and yield insight into adsorption interactions and strengths. Significant guest-induced changes in the crystal structure of MIL-53 are revealed by powder X-ray diffraction experiments; specific unique phases of MIL-53 are related to the identity of the guest molecule and its binding mechanism to the framework. 27Al and 13C solid-state NMR experiments probe the interaction between guest molecules and MIL-53. The relationship between the nature of the guest, the structure of MIL-53, and 27Al NMR parameters is explored. 27Al NMR parameters are sensitive to the host-guest binding mechanism (i.e., hydrogen-bonding or π–π stacking interactions) and yield valuable information regarding the influence of the adsorbates on the local aluminum environment. This combination of physical characterization techniques is a useful probe of guest adsorption and the breathing effect within MIL-53 and should prove useful for investigation of related MOFs.

Abstract:
Abstract Metal-organic frameworks (MOF(n)) are organic-inorganic hybrid crystalline porous materials that consist of a regular array of positively charged metal ions surrounded by organic ‘linker’ molecules. The metal ions form nodes that bind the arms of the linkers together to form a repeating, cage-like structure. Moreover, in a chemical structure or molecular graph, edges and vertices are known as bonds and atoms, respectively. Metric dimension being a subsets of atoms with minimum cardinality is used in the substrcturing of the chemical compounds in the molecular structures. Fractional metric dimension is weighted version of metric dimension that associate a numeric value to the identified subset of atoms. In this paper, we have computed the fractional metric dimension of metal organic framework (MOF(n)) for n ≡ 0(mod)2.

Abstract:
Metal-organic frameworks (MOFs) have been intensely researched over the past 20 years. In this dissertation, metal-inorganic frameworks (MIFs), a new class of porous and nonporous materials using inorganic complexes as linkers, in lieu of traditional organic linkers in MOFs is reported. Besides novel MIF regimes, the previously described fluorous MOF "FMOF-1", is re-categorized herein as "F-MIF1". F-MIF-1 is comprised of [Ag4Tz6]2- (Tz = 3,5-bis-trifluoromethyl-1,2,4-triazolate) inorganic clusters connected by 3-coordinate Ag+ metal centers. Chapter 2 describes isosteric heat of adsorption studies of F-MIF1 for CO2 at near ambient temperatures, suggesting promise for carbon capture and storage. We then successfully exchanged some of these Ag(I) centers with Au(I) to form an isostructural Au/F-MIF1. Other, nonporous MIFs have been synthesized using Ag2Tz2 clusters with bridging diamine linkers 4,4'-bipyridine, pyrazine, and a Pt(II) complex containing two oppositely-situated non-coordinating pyridines. This strategy attained luminescent products better-positioned for photonic devices than porous materials due to greater exciton density. Chapter 3 overviews work using an entirely inorganic luminescent complex, [Pt2(P2O5)4]4- (a.k.a. "PtPOP") to form new carbon-free MIFs. PtPOP is highly luminescent in solution, but as a solid shows poor quantum yield (QY ~0.02) and poor stability under ambient conditions. By complexing PtPOP to various metals, we have shown a dramatic enhancement in its solid-state luminescence (by an order of magnitude) and stability (from day to year scale). One embodiment (MIF-1) demonstrates microporous character. Chapter 4 overviews the design and application of new MIF linkers. Pt complexes based upon (pyridyl)azolates, functionalized with carboxylic acid groups, have been synthesized. These complexes, and their esterized precursors, show strong luminescence on their own. They have been used to generate new luminescent MIFs. Such new MIFs may be useful toward future inorganic (LEDs) or organic (OLEDs) light-emitting diodes, respectively. The electronic communication along their infinite coordination structures is desirable for color tuning and enhanced conductivity functions, compared to the small molecules used in such technologies, which rely on intermolecular interactions for these functions.

Ce travail est une contribution à la compréhension des performances de matériaux hybrides poreux de type MOFs pour le captage de benzène, dans le cadre de la lutte contre les émissions de Composés Organiques Volatils (COVs) à partir de procédés basés sur l'adsorption d'effluents gazeux. Dans ce but, nous avons couplé diverses techniques expérimentales (spectroscopie d'impédance complexe, diffraction des rayons X, manométrie d'adsorption, …) à des simulations moléculaires (calculs basés sur la Théorie de la Fonctionnelle de la Densité, Monte Carlo ou Dynamique Moléculaire) pour étudier ces matériaux en termes de capacité et de mécanisme d'adsorption. Différentes familles de MOFs ont été sélectionnées afin d'analyser l'impact de diverses caractéristiques de ces matériaux, comme la flexibilité du réseau, la présence de cations extra-réseau et la nature chimique des ligands organiques, sur leurs propriétés d'adsorption de benzène. Par ailleurs, l'eau étant souvent considérée comme un facteur limitant lors de l'adsorption sélective d'une espèce à partir d'effluents gazeux chargés d'humidité, nous avons également envisagé l'étude de cet adsorbat seul, avant d'explorer la co-adsorption de mélanges benzène/eau dans des proportions différentes. Une rationalisation des données nous a permis de conclure que certains des matériaux explorés présentent une sélectivité benzène/eau intéressante pour envisager leur utilisation potentielle dans le cadre du captage de traces
The Metal Organic Frameworks (MOFs), a recent class of hybrid porous solids, appears as valuable candidates for various applications related to their sorption abilities. The optimization of their performances requires a control of the parameters that govern the adsorption process, including the confined species/MOF interactions and the synergic dynamics of the system. In this context, experimental tools (Complex Impedance Spectroscopy, X Ray Diffraction, volumetric adsorption…) were combined with molecular simulations (Density Functional Theory, Monte Carlo and Molecular Dynamics calculations) to explore the benzene adsorption of MOFs in terms of capacity and microscopic mechanism. Different series of MOFs were selected to address the impact of various features, including the lattice flexibility, the presence of extra-framework cations and the ligand functionalization, on their adsorption performances. Benzene and water were considered as adsorbents separately, before exploring the co-adsorption of various benzene/water mixtures. The rationalization of the data allowed us to understand why some of the selected solids, showing interesting benzene/water selectivity, are likely to be used for the capture of benzene traces in humid conditions

Metal-Organic Frameworks (MOFs) as high-porosity structures have huge potential in many fields, such as energy storage and conversion, UiO-67 is widely used, especially in scenarios where thermal stability and alkaline environments are required. Here this project will induct Cu@UiO-67 and Cu@UiO-bpy could be electrochemical catalysts for CO2RR under alkaline conditions. It investigated the factor of reacting with different copper sources and their reaction durations, and the components of these two-catalyst ink were considered as variables to be studied. Post-synthesis method was employed to construct the guest-encapsulated MOF structure. At the optimum mass ratio of Cu@UiO-67/Cu@UiO-bpy: carbon black 4:1 the Faradaic efficiency of C2+ products were 53.35% and 65.12%, respectively, which was achieved under a large current density of 500 mA/cm2 in the flow cell.

Abstract:
Metal-organic frameworks (MOFs) have been attracting great attention in the past several decades mainly because of their amazing properties, including tunable surface chemistry, flexible structure, large surface area, and huge porosity. Endorsed by those merits, MOFs have been applied in a wide range of applications, such as catalysis, gas separation, drug delivery, and sensing. Typically, MOFs are synthesized via the hydrothermal method, which, however, is difficult to scale up and requires long reaction durations (e.g., from hours to days). To achieve the full potentials of MOFs, the exploration of a novel strategy is necessary for the facile and fast synthesis of MOFs. Here in this dissertation, the aerosol route was presented as a facile route to synthesize MOFs and MOF-based composites. The aerosol route not only enabled fast crystallization of MOFs (i.e., within seconds), but also allowed continuous tuning of MOF’s properties by simply adjusting the operating parameters (e.g., temperature, pressure, and precursor conditions). To map out the formation mechanism of MOFs inside the microdroplets, systematic experimental and simulation work were carried out, which demonstrated that the fast heat and mass transfer during the aerosol route played a vital role in the rapid synthesis of MOFs. Beyond the synthesis of MOFs, the photocatalytic applications of MOF-based materials for energy and environmental sustainability were also studied in detail. More specifically, several efficient MOF-based composite photocatalysts were designed, including HKUST-1/TiO2, HKUST-1/TiO2/Cu2O, ZIF-8/ZnO, and MIL-100(Fe)/TiO2. The composite photocatalysts exhibited remarkable efficiencies towards either CO2 photoreduction or water remediation. In-depth exploration of the photocatalytic mechanism was carried out with the aid of several advanced techniques, such as in situ diffuse reflectance infrared Fourier spectroscopy (DRIFTS), photoluminescence spectroscopy, grazing-incidence wide-angle X-ray scattering, and ultrafast transient absorption spectroscopy. Meanwhile, the density functional theory (DFT) calculation was also applied to provide further mechanistic insights. The results demonstrated that MOFs acted as excellent co-catalysts, which not only facilitated molecule adsorption and activation, but also promoted the separation of the photo-induced charge carriers, leading to increased charge carrier densities in the photocatalytic systems for significantly enhanced efficiencies. The work from this dissertation is expected to broaden the synthesis strategies for the synthesis of MOF-based materials and advance the fundamental understanding of MOFs’ roles in photocatalytic applications, which should have a great impact on the rational design of MOF-based composite photocatalysts for energy and environmental sustainability.

Abstract:
Advances in flexible and functional metal–organic frameworks (MOFs), also called soft porous crystals, are reviewed by covering the literature of the five years period 2009–2013 with reference to the early pertinent work since the late 1990s. Flexible MOFs combine the crystalline order of the underlying coordination network with cooperative structural transformability. These materials can respond to physical and chemical stimuli of various kinds in a tunable fashion by molecular design, which does not exist for other known solid-state materials. Among the fascinating properties are so-called breathing and swelling phenomena as a function of host–guest interactions. Phase transitions are triggered by guest adsorption/desorption, photochemical, thermal, and mechanical stimuli. Other important flexible properties of MOFs, such as linker rotation and sub-net sliding, which are not necessarily accompanied by crystallographic phase transitions, are briefly mentioned as well. Emphasis is given on reviewing the recent progress in application of in situ characterization techniques and the results of theoretical approaches to characterize and understand the breathing mechanisms and phase transitions. The flexible MOF systems, which are discussed, are categorized by the type of metal-nodes involved and how their coordination chemistry with the linker molecules controls the framework dynamics. Aspects of tailoring the flexible and responsive properties by the mixed component solid-solution concept are included, and as well examples of possible applications of flexible metal–organic frameworks for separation, catalysis, sensing, and biomedicine.

Abstract:
Le dioxyde de carbone (CO2), principal contaminant des gaz naturels bruts et du biogaz doit être extrait en vue d’un enrichissement en méthane (CH4) compatible avec les spécifications d’injection en réseaux de gaz naturel. Au cours des dernières années, une famille de matériaux poreux de type réseaux organométalliques à base de magnésium (Mg-MOF-74) a ouvert une nouvelle perspective à cet effet en raison d’une excellente affinité des sites métalliques exposés au sein de la structure cristalline pour l’adsorption du CO2. Ce matériau est un adsorbant potentiellement bon candidat pour l’enrichissement en CH4 de gaz naturel et de biogaz par des procédés opérant en modulation de pression. La présente étude propose d’examiner l’amélioration des performances d'adsorption du CO2 en mélange avec le CH4 par dopage du matériau Mg-MOF-74 avec des nanotubes de carbone et de l'oxyde de graphène. L'objectif est d'améliorer les propriétés texturales pour favoriser la diffusion des molécules des gaz dans les micropores et leur accessibilité aux sites d'adsorption. Les matériaux ont été synthétisés sous réaction solvothermique et caractérisés par DRX, IRTF, MEB, ATG et physisorption d’azote à 77K. Les équilibres et énergies d'adsorption ont été mesurées suivant une méthode manométrique dans une gamme de pression allant jusqu'à 35 bar et à 25°C, 50°C et 75°C. La cinétique de sorption a été étudiée à partir d’expériences de manométrie et de la méthode dite « Zero Length Column » à 25°C, 50°C et 75°C. A une teneur optimisée à 0,3% en masse d’agent dopant, le modèle de Brunauer–Emmett–Teller montre que la surface spécifique des matériaux dopés est augmentée de plus de 21% par rapport à celle du matériau non-dopé. Les données d'équilibre indiquent que la capacité d’adsorption en CO2 est sensiblement améliorée pour les matériaux dopés dans toute la gamme opératoire étudiée, tandis qu’ils démontrent une sélectivité comparable ou améliorée, dépendante de la température
Carbon dioxide (CO2), which is the major contaminant present in raw natural gas and biogas need to be extracted to increase their methane (CH4) content and match the standards of pipeline injection. In recent years, a family of porous materials, magnesium-based Metal Organic Framework (Mg-MOF-74), has opened new perspectives for this purpose thanks to strong adsorption affinity of CO2 with exposed metallic sites in the crystalline network. This material is a potential good adsorbent candidate for the enrichment in CH4 of natural gas and biogas by Pressure Swing Adsorption processes. The present study proposes to examine the CO2 adsorption performances and separation ability from CH4 of Mg-MOF-74 materials doped with carbon nanotubes and graphene oxide. The objective is to improve the texture of the materials to promote the diffusion of gas molecules into micropores and their accessibility to adsorption sites. The materials were synthesized under solvothermal reaction and characterized by PXRD, FTIR, FESEM, TGA and physisorption of nitrogen at 77K. The adsorption equilibria and energies were measured using manometric method in a pressure range up to 35 bar and at 25°C, 50°C and 75°C. The sorption kinetics of CO2 and CH4 on the materials were studied from manometric experiments and using the Zero Length Column method at 25°C, 50°C and 75°C. At an optimized content of the doping agents of 0.3 wt%, Brunauer–Emmett–Teller model shows that the specific surface area is increased for both composites, by more than 21% compared to the pristine material. The equilibrium data indicates that the CO2 adsorption capacity is significantly improved in the whole range of operating conditions for both composites compared to the pristine material, whereas the CO2/CH4 adsorption selectivity appears either comparable or better as a function of temperature

Abstract:
Ce travail a pour objectif l’étude de matériaux hybrides poreux de type Metal-Organic Frameworks (MOFs) et d’un cristal moléculaire en tant que conducteurs ioniques solides pour des applications dans le domaine de l’énergie et de l’environnement. Dans le premier cas, nous avons développé diverses stratégies pour optimiser et contrôler la teneur en sites acides de Lewis et en porteurs de charges de deux séries de MOFs afin de concevoir des matériaux aux propriétés de conduction protonique très prometteuses. A partir d’une approche basée sur la substitution progressive des ligands par des entités fonctionnalisées présentant des sources de protons acides, nous avons créé une série de MOFs, MIP-207-(SO3H-IPA)x-(BTC)1–x, dont la teneur en groupements sulfoniques, par l’intermédiaire du ligand SO3H-IPA, est contrôlée à façon. Le meilleur matériau qui combine stabilité structurale et conduction protonique élevée présente des performances sous humidité parmi les plus intéressantes au sein de la famille des MOFs conducteurs protoniques (e.g., σ = 2.6 × 10–2 S cm–1 à 363 K/95% d’humidité relative (RH)). Selon une autre approche, nous avons étudié un MOF mésoporeux connu (MIL-101(Cr)-SO3H) dont les parois des pores sont tapissées de sites protoniques et qui contient dans ses pores un liquide ionique, le chlorure chlorure de 1-Ethyl-3-methylimidazolium (EMIMCl) capable d’assurer le transfert de proton. L’encapsulation du liquide ionique, caractérisée par une série d’outils expérimentaux (sorption de diazote, DRX sur poudre, TGA/MS, DSC et analyse élémentaire), s’avère particulièrement efficace pour exalter les propriétés de conduction protonique des composites à la fois à l’état anhydre (σ473 K = 1.5 × 10-3 S cm-1) mais également à l’état hydraté (σ(343 K/60%-80%RH) ≥ 0.10 S cm-1). Enfin, ce travail a été étendu à une autre famille de solides poreux, à travers l’étude des propriétés de conduction ionique d’un cristal moléculaire à base de zirconium (Zr-3) qui contient des paires ioniques KCl. Nous avons démontré que ZF-3 transite d’un comportement isolant à l’état anhydre (σ = 5.1 x 10-10 S cm-1 à 363 K/0% RH) vers un comportement super-conducteur ionique en présence d’eau (σ = 5.2 x 10-2 S cm-1 à 363 K/95 % RH), suite à l’augmentation de la dynamique de ions Cl- sous hydratation. Par ailleurs, des simulations moléculaires ont permis de décrire les mécanismes microscopiques à l’origine des propriétés de conduction des matériaux étudiés. Ces avancées devraient permettre de développer dans le futur de nouveaux matériaux performants dans le domaine de la conduction protonique et ionique
The conductivity performance of a new series of chemically stable proton conducting Metal Organic Frameworks (MOFs) as well as a superionic molecular crystal was explored. The contribution of this PhD was to (i) select a variety of architectures and functionalities of robust MOFs/superionic molecular solids and (ii) characterize and rationalize their conducting performance over various temperature/humidity conditions. We designed two series of MOFs to achieve promising proton-conducting performance, using distinct approaches to modulate the concentration of Brønsted acidic sites and charge carriers and further boost the conductivity properties. First, a multicomponent ligand replacement strategy was successfully employed to elaborate a series of multivariate sulfonic-based solids MIP-207-(SO3H-IPA)x-(BTC)1–x which combine structural integrity with high proton conductivity values (e.g., σ = 2.6 × 10–2 S cm–1 at 363 K/95% Relative Humidity -RH-). Secondly, a proton conducting composite was prepared through the impregnation of an ionic liquid (1-Ethyl-3-methylimidazolium chloride, EMIMCl) in the mesoporous MIL-101(Cr)-SO3H. The resulting composite displaying high thermal and chemical stability, exhibits outstanding proton conductivity not only at the anhydrous state (σ473 K = 1.5 × 10-3 S cm-1) but also under humidity (σ(343 K/60%-80%RH) ≥ 0.10 S cm-1) conditions. Finally, the ionic conducting properties of another class of porous solids, considering a zirconium-formate molecular solid containing KCl ion pairs (ZF-3) were explored. ZF-3 switches from an insulator (σ = 5.1 x 10-10 S cm-1 at 363 K/0% RH) to a superionic conductor upon hydration (σ = 5.2 x 10-2 S cm-1 at 363 K/95 % RH), in relation with the boost of Cl- dynamics upon water adsorption. Noteworthy, quantum- and force-field based simulations were combined with the experimental approach to elucidate the microscopic mechanisms at the origin of the ionic conducting properties of the studied materials. This fundamental knowledge will serve to create novel robust superionic conductors with outstanding performances that will pave the way towards appealing societal applications for clean energy production

Abstract:
Crystalline particles known as Metal Organic Frameworks (MOF’s) are known for their large surface area and high adsorption and storage capacity for CO2 gas. Electrospun nanofibers are considered as ideal substrates for synthesizing the MOF particles on the fiber surface. In this project, Polyacrylonitrile (PAN) and a Cu-based MOF known as HKUST-1 were selected as substrate fibers and adsorbent particles respectively. A precursor solution of PAN polymer hybridized with HKUST-1 particles dissolved in Dimehtylformamide (DMF) is used as the primary component solution for electrospinning. SEM images of the electrospun fibers showed small MOF particles formation into the fiber structure. A secondary solvothermal process of MOF particles growing on the fibers was then executed to increase the amount of MOF particles for effectual gas adsorption. The secondary process consists of multiple growth cycles and SEM images showed uniform distribution of porous MOF particles of 2–3μm in size on the fiber surface. EDS report of the fiber confirmed the presence of MOF particles through identification of characteristic Copper elemental peaks of HKUST-1. Thermogravitmetric analysis (TGA) of HKUST-1 doped PAN fiber displayed 32% of total weight loss between 180°C and 350°C thus proving the as-synthesized MOF particles are thermally stable within the mentioned temperature range. A comparative IR spectroscopic result between the gas-treated and gas-untreated fiber samples showed the presence of characteristic peak in the vicinity of 2300 and 2400cm−1 which corroborates the assertion of adsorption of CO2 on the system. Further step involved is to investigate the gas adsorption capacity of the filter system in an experimental test bench. Non-dispersive Infrared (NDIR) CO2 sensors will be used at the gas inlet and outlet parts to measure the concentration of CO2 and determine the amount of gas uptake by the filter system.

Abstract:
Abstract Contamination of heavy metals especially for Mercury (Hg) and Arsenic (As) in condensates becomes one of major concerns in Natural Gas production due to theirs high toxicity and carcinogenicity. The key challenge to develop adsorbents for Hg/As removal is to find suitable porous materials with high adsorption capacity, long-term stability and easy to handle the toxic wastes after the adsorption process. Metal-organic frameworks (MOFs) are one of promising porous materials constructed from metal clusters and organic linkers to create the 3D framework structures. MOFs are one of the promising adsorbents for removal of Hg/As from condensates owning to their versatile structures, tunable porosity, and tailorable chemical functionalities. In this work, Zr-based MOFs have been developed for dual removal of Hg and As species owning to their chemical stability in moisture conditions, which is highly desirable for industrial processes. Zr-based MOFs with different topology and pore size distribution have been synthesized for Hg/As adsorption to understand the contribution of porous structure on the removal of Hg/As species in condensates. The performance of Zr-based MOFs results showed Hg and As removal up to 99.5% in condensates from several petroleum sources. The removal efficiencies were found to be influenced by topology of MOF adsorbents and the speciation of Hg/As in different petroleum sources. In addition, Zr-based MOFs have proposed some future trends and challenges of porous material that can be used as an alternative to the conventional metal oxides and zeolites.

Abstract:
Background: Cardiovascular diseases (CVDs) are considered the major cause of death worldwide. Therapeutic delivery to the cardiovascular system may play an important role in the successful treatment of a variety of CVDs, including atherosclerosis, ischemic-reperfusion injury, and microvascular diseases. Despite their clinical benefits, current therapeutic drugs are hindered by their short half-life and systemic side effects. This limitation could be overcome using controlled drug release with the potential for targeted drug delivery using a nanomedicine approach. In the current study, we have assessed the use of a highly porous nano-sized preparation of iron-based Metal-organic Framework (MOF) commonly referred to as MIL-89 as potential drug carriers in the cardiovascular system. Aims: To assess the effect of MOFs on the viability and cytotoxicity of human vascular cells and the cellular uptake in vitro, and the organ-system toxicity of MOF in vivo using the Zebrafish model. Methods: Human pulmonary endothelial cells (HPAECs) and pulmonary smooth muscle cells (HPASMCs) were treated with variable concentrations of MOFs. The viability, cytotoxicity and anti-inflammatory effects were measured using AlamarBlue, LDH assay and ELISA. The cellular uptake of MOFs were assessed using light, confocal, and transmission electron microscopes and EDS analysis. Moreover, Zebrafish embryos were cultured and treated with MOFs-nanoparticles at 0 hours post fertilization (hpf) followed by different organ-specific assays at 24, 48, and 72 hpf. Results: Although MOFs affect the viability at high concentrations, it does not cause any significant cytotoxicity on HPAECs and HPASMCs. Interestingly, MOFs were shown to have an anti-inflammatory effect. Microscopic images showed an increased (concentration-dependent) cellular uptake of MOFs and transfer to daughter cells in both cell types. Moreover, the in vivo study showed that high concentrations of MOFs delay zebrafish embryos hatching and cause heart deformation, which is currently investigated using cardiotoxicity markers. Conclusion: MOFs is a promising nanoparticle prototypes for drug delivery in the cardiovascular system with high cellular uptake and anti-inflammatory effects. Further investigations of MOFs, including diseased models and drug- loaded formulation is required.

Abstract:
We report a resonant gas sensor, uniformly coated with a metal-organic framework (MOF), and excited it near the higher order modes for a higher attained sensitivity. Also, switching upon exceeding a threshold value is demonstrated by operating the resonator near the bifurcation point and the dynamic pull-in instabilities. The resonator is based on an electrostatically excited clamped-clamped microbeam. The microbeam is fabricated from a polyimide layer coated from the top with Cr/Au and from the bottom with Cr/Au/Cr layer. The geometry of the resonator is optimized to reduce the effect of squeeze film damping, thereby allowing operation under atmospheric pressure. The electrostatic electrode is designed to enhance the excitation of the second mode of vibration with the minimum power required. Significant frequency shift (kHz) is demonstrated for the first time upon water vapor, acetone, and ethanol exposure due to the MOF functionalization and the higher order modes excitation. Also, the adsorption dynamics and MOF selectivity is investigated by studying the decaying time constants of the response upon gas exposure.
