Abstract:
Abstract A special site on the (+) strand of the L-A dsRNA virus induces about 2% of ribosomes translating the gag open reading frame to execute a -1 frameshift and thus produce the viral gag-pol fusion protein. Using constructs in which a -1 ribosomal frameshift at this site was necessary for expression of lacZ we isolated chromosomal mutants in which the efficiency of frameshifting was increased. These mutants comprise eight genes, named mof (maintenance of frame). The mof1-1, mof2-1, mof4-1, mof5-1 and mof6-1 strains cannot maintain M1 dsRNA at 30 degrees, but, paradoxically, do not lose L-A. The mof2-1, mof5-1 and mof6-1 strains are temperature sensitive for growth at 37 degrees, and all three show striking cell cycle phenotypes. The mof2-1 strains arrest with mother and daughter cells almost equal in size, mof5-1 arrests with multiple buds and mof6-1 arrests as single large unbudded cells. mof2-1 and mof5-1 strains are also Pet-. The mof mutations show differential effects on various frameshifting signals.

Abstract:
Moringa oleifera (MO) is a plant of significant medicinal importance. The dried leaves of MO were pulverized, extracted with ethanol and fractionated using column chromatography to provide seven fractions (MOF1-7) with MOF6 having the best preliminary antioxidant potential. Therefore, this study evaluated the hepatoprotective potentials of MOF6 in sodium arsenite (SA)-induced hepatotoxicity in rats. Thirty-five adult male Wistar rats were randomly divided into seven groups of five rats each. Control Group I received normal saline. Groups II and III received 20 mg/kg body weight (bw) of SA for 3 and 6 weeks, respectively. Groups IV and V received 20 mg/kg bw of SA for 3 weeks followed by treatment with 5.0 and 7.5 mg/kg bw of fraction MOF6, respectively, for 6 weeks. Groups VI and VII received only 5.0 and 7.5 mg/kg bw of fraction MOF6, respectively, for 6 weeks. Antioxidant (lipid peroxidation) and biochemical analyses of liver enzymes of all rats were carried out after the completion of experimental procedures. Results showed statistically significant lower mean values (p ≤ 0.05) of malondialdehyde (MDA), acid phosphatase (ACP) and γ-glutamyl transferase (GGT) in rats of Groups IV and V compared with Group III. However, there were statistically significant higher mean values (p ≤ 0.05) of alkaline phosphatase (ALP) in Groups IV and V compared with Groups I and III. In conclusion, these results implied that fraction MOF6 has antioxidant and hepatoprotective potentials. However, results of ALP analyses implied that MOF6 possibly augmented SA-induced hepatotoxicity in rats.

Abstract:
Infrared multiple-photon dissociation (IRMPD) of MoF6 has been investigated with a parallel beam of a para-H2 Raman laser newly developed by our group. MoF6 gas (2 Torr, natural abundance) was put into in a static cell cooled to −58℃ and was irradiated with the laser line at 728 cm−1. The critical fluence of 0.11 Jcm−2 for complete dissociation was determined by analysis with a Gaussian beam model. Irradiation at the lower frequency side (728 cm−1) of the MoF6 ν3 band enriched the lighter isotopes in the residue. A maximum value for selectivity of 1.1 was obtained.

Abstract:
This study evaluated the neuroprotective effects of MOF6 (isolated from Moringa oleifera leaves) and Trimyristin (isolated from Myristica fragrans seeds) on Acetylcholinesterase concentrations in cerebral cortices of rats with Sodium arsenite-induced neurotoxicity. Sixty-five adult male rats (150 g-250 g) were randomly divided into thirteen groups comprising of five rats per group. Groups 1 and 3 received physiological saline and 1 ml/200 g bodyweight of Olive oil respectively for 9 weeks. Group 2 received 20 mg/kg bodyweight of Sodium arsenite (SA) for 6 weeks and left untreated for another 3 weeks. Groups 4-5 received 20 mg/kg bodyweight of SA for 3 weeks followed by treatments with 5.0 and 7.5 mg/kg bodyweight of MOF6 respectively for 6 weeks. Groups 6-7 received 20 mg/kg bodyweight of SA for 3 weeks followed by treatments with 15 and 30 mg/kg bodyweight of Trimyristin respectively for 6 weeks. Groups 8-11 received 5.0 and 7.5 mg/kg bodyweight of MOF6; 15 and 30 mg/kg bodyweight of Trimyristin respectively for 9 weeks. Groups 12-13 received 7.5 mg/kg bodyweight of MOF6 and 30 mg/kg bodyweight of Trimyristin respectively for 6 weeks followed by co-administration of each extract dose with 20 mg/kg bodyweight of SA for another 3 weeks. Histological examination of cerebral cortices and biochemical analyses of Acetylcholinesterase concentrations were carried out in all rats. Computed data were analyzed using Microsoft Excel 2016 with statistical significance at p≤0.05. Histo-pathological evaluations revealed normal histo-architecture of cerebral cortices of all rats. Results showed statistically significant (p≤0.05) increases in Acetylcholinesterase concentrations in rats of Groups 1-10 and 12 compared with Group 2 (2.78±1.76 𝜇mole/min/g). 7.5 mg/kg bodyweight of MOF6 showed the best therapeutic and neuro-regenerative potential against SA-induced neurotoxicity.Conclusions: Our findings implied that MOF6 and Trimyristin reversed downregulation of Acetylcholinesterase concentrations in SA-induced neurotoxicity in rats; and possess neuro-protective and neuro-regenerative potentials.

Abstract:
The chemical vapor deposition (CVD) of MoS2 by reaction of H2S with molybdenum halides was determined to be thermodynamically favored over a wide range of temperature, pressure, and precursor concentration conditions as long as excess H2S was available. The thermochemical stability of H2S, MoF6, and MoCI5 was also assessed to address their suitability as precursors for the CVD of MoS2. The results from the thermodynamic analysis were used as guidance in the deposition of MoS2 thin films from MoF6 and H2S. The (002) basal planes of MoS2 films deposited above 700 K were preferentially oriented perpendicular to the substrate surface.

Abstract:
The molybdenum and tungsten complexes M2(OR)6 (Mo2F6, M = Mo, R = C(CF3)2Me; W2F3, M = W, R = OC(CF3)Me2) were synthesized as bimetallic congeners of the highly active alkyne metathesis catalysts [MesC≡M{OC(CF3) n Me3− n }] (MoF6, M = Mo, n = 2; WF3, M = W, n = 1; Mes = 2,4,6-trimethylphenyl). The corresponding benzylidyne complex [PhC≡W{OC(CF3)Me2}] (W Ph F3) was prepared by cleaving the W≡W bond in W2F3 with 1-phenyl-1-propyne. The catalytic alkyne metathesis activity of these metal complexes was determined in the self-metathesis, ring-closing alkyne metathesis and cross-metathesis of internal and terminal alkynes, revealing an almost equally high metathesis activity for the bimetallic tungsten complex W2F3 and the alkylidyne complex W Ph F3. In contrast, Mo2F6 displayed no significant activity in alkyne metathesis.

Abstract:
The de Haas van Alphen (dHvA) effect of the stage-1 MoF6− graphite intercalation compound was investigated in magnetic fields up to 5.5 T. The dHvA-frequency spectrum of the stage-1 compound consists of a high frequency, a midfrequency, and a set of low frequencies. The dominant oscillation is the high frequency at 1530 T. It is associated with the single graphite energy band of the stage-1 compound. The cyclotron mass of the carrier with the dominant frequency is 0.31 m0 where m0 is the free-electron mass. The electron charge transfer per intercalated MoF6− molecule is 0.3 for the C8.4MoF6 compound. The low frequencies and midfrequencies are compared with those in other stage-1 chloride graphite intercalation compounds.

Abstract:
Die Entwicklung und Synthese im Bereich neuartiger poröser Systeme, im speziellen Metallorganische Gerüstverbindungen (engl.: Metall-organic Frameworks; MOFs), wird weltweit in vielen Forschergruppen intensiv bearbeitet. Aufgrund der Möglichkeit, dass sich die Materialeigenschaften individuell designen lassen und letztendlich spezifische Eigenschaften für eine ausgewählte Anwendung bereitgestellt werden können, stellen MOFs für einen weiten Forscherkreis eine interessante Materialienklasse dar. Im Rahmen dieser Arbeit stand die Synthese von neuartigen MOFs im Vordergrund, welche geeignete Eigenschaften für eine effiziente Speicherung von Gasen im Nieder- als auch im Hochdruckbereich besitzen. Dabei wurde zum einen Augenmerk auf die Synthese mesoporöser MOF-Systeme gelegt. Hier lag die größte Herausforderung darin, die erhaltenen hochporösen Materialien in einer stabilen gastfreien Form zu erhalten. Ein weiterer Schwerpunkt war die Untersuchung von flexiblen MOF-Verbindungen und deren Eigenschaften in Abhängigkeit der Synthesebedingungen und der adsorbierten Spezies. Auf Basis der Copolymerisation verschiedener multifunktioneller Linkermoleküle konnten zwei mesoporöse Verbindungen und dazugehörige Isomorphe synthetisiert werden (DUT-6, DUT-23; DUT = Dresden University of Technology). Mit diesen Verbindungen konnte über die Kombination von unterschiedlich funktionellen Linkermolekülen eine erhöhte Netzwerkstabilität und damit einhergehend erhöhte Porosität erhalten werden. Sämtliche Verbindungen zeigen ausgezeichnetes adsorp-tives Verhalten und können aufgrund ihrer verschiedenen Eigenschaften in Bereichen der Hochdruckadsorption, Katalyse oder enantioselektiven Trennung Einsatz finden. Im zweiten Teil der Arbeit wurde das flexible Verhalten der „pillar-layer“ Verbindungen DUT-8(M) (M = Ni, Co, Zn, Cu) näher untersucht. Diese isomorphe Reihe zeichnet sich durch ihre hohe Netzwerkflexibilität in Abhängigkeit der integrierten Gastmoleküle sowie dem vorliegendem Metall-Dimer aus. DUT-8(M) zeigt unterschiedliche Adsorptionseigenschaften und unterschiedliches Stabilitäts- sowie Flexibilitätsverhalten.

Abstract:
In this work the magnesium, zinc, nickel and cobalt MOFs of the MOF-74 isostructural family are used to probe metal-dependent adsorbate interactions with water and with carbon monoxide because of their ability to generate open metal sites upon activation. An isostructural family is used so that the only variable from one MOF to another is the metal incorporated into the framework. For water adsorption isotherms with humidities up to 90%, the observed trend at 298K and 1 bar is Mg-MOF-74 > Zn-MOF-74 > Co-MOF-74 > Ni-MOF-74. This observed trend is due to Lewis acid-base interactions. When the weight effect is removed, differences are still observed, especially below 40% relative humidity, thereby confirming that there is a metal effect. These studies revealed that PXRD alone cannot indicate the level of structural decomposition and that none of the four isostructures fully retain their structural integrity on exposure to humidified air because of microstrain and/or the presence of oxygen; more studies examining the extent of structural decomposition need to be undertaken. For carbon monoxide adsorption the general observed trend for P < 4 bar and temperatures of 298, 313 and 333K is Co-MOF-74 > Ni-MOF-74 > Zn-MOF-74 > Mg-MOF-74. This trend is based on π-backbonding interactions. Here again, differences remain after removal of the weight effect, confirming the metal dependence. Notably, Co-MOF-74 has the highest CO loading at 298K and 1 bar reported so far. Both the Toth and Virial Isotherms were used to fit the CO adsorption data followed by the use of the Clausius-Clapeyron equation to find the isosteric heats of adsorption, qst. The results from the Toth isotherm are more reliable and showed that qst remains constant as loading increases for Mg-MOF-74, decreases for Zn-MOF-74 and increases with loading for Co-MOF-74 and Ni-MOF-74; Ni-MOF-74 had the highest heat of adsorption at all loadings. It appears that using the Clausius-Clapeyron equation to calculate qst is an inappropriate method for Ni-MOF-74 so other methods such as calorimetry are recommended. It is also recommended to model the data of all the MOFs with other isotherm models such as Sips equation and to investigate the possibility of chemisorption for the cobalt and nickel isostructures. Finally, Henry’s constant results reveal that Ni-MOF-74 has the highest affinity for CO at low coverages.

Abstract:
In dieser Arbeit werden das Potential der mechanochemischen Synthesemethode zur Herstellung von metallorganischen Gerüstverbindungen (MOFs) vorgestellt und mögliche Anwendungsgebiete aufgezeigt. Im Forschungsfokus bezüglich schnellerer und effizienterer Darstellungsmethoden ist die Mechanochemie eine aussichtsreiche Alternative. Die Feststoff-Reaktion ist ohne die Verwendung von Lösungsmitteln durchführbar, zeichnet sich durch verkürzte Reaktionszeiten und quantitativen Eduktumsatz aus und gilt somit als Green Chemistry-Methode, die stetig wachsende Bedeutung erlangt. Die Ergebnisse dieser Arbeit belegen, dass über die mechanochemische Synthese metallorganische Verbindungen in allen Dimensionalitäten herstellbar sind. Die Reaktionsparameter sind auf die Herstellung isostruktureller und strukturanaloger Verbindungen übertragbar. Es wurden Synthesebedingungen identifiziert, die die Produktbildung beeinflussen, so dass ihre Kontrolle zur gezielten Herstellung verschiedener Verbindungen diente. Des Weiteren wurden Reaktionsparameter ermittelt, die einen Einfluss auf die Eigenschaften des Produkts ausüben. Im Hinblick auf eine größtmögliche spezifische Oberfläche wurde die Synthese optimiert und eine postsynthetische Aktivierungsprozedur entwickelt, die gemeinsam in einer verbesserten Gasadsorptionskapazität resultieren und auf andere Verbindungen übertragbar sind. Die Ergebnisse zur Gasspeicherung zeigen ein erstes Anwendungspotential für mechanochemisch synthetisierte MOFs auf, die als feine Pulver mit vergrößerter Oberfläche erhalten werden. Weiterhin wurde die Einlagerung von Solvensmolekülen in die Poren eines MOFs untersucht. Dabei zeigte sich, dass das MOF seine Gitterparameter an die jeweiligen Gastmoleküle anpasst. Das Potential zur Interkalation von Feststoffen wird anhand der Einlagerung pharmazeutischer Wirkstoffmoleküle belegt. Katalytische Untersuchungen zeigen eine gute Aktivität des mechanochemisch synthetisierten Rohprodukts.<br>In this work the potential of mechanochemical synthesis to produce metal-organic frameworks (MOFs) is presented and possible applications for the materials are shown. In the focus of research regarding faster and more efficient methods of synthesis, mechanochemistry is an promising alternative. This solid-state reaction can be carried out without the use of solvent, exhibits shortened reaction times and a quantitative turnover of reactands. Therefore it is a method of green chemistry, and its importance is constantly increasing. The results show that mechanochemical synthesis is capable of producing metal-organic compounds in all dimensionalities. The reaction conditions can be transferred to synthesize isostructural and structural analogous compounds. Parameters influencing the formation of products were identified, and their control led to a well-aimed design of various compounds. In addition, conditions influencing the properties of the product were determined. In terms of a specific surface area as large as possible, the synthesis was optimized and a postsynthetic activation was developed, together resulting in an improved capacity for gas adsorption and transferrable to other compounds. The results concerning gas storage present one possible application of mechanochemically synthesized MOFs, that are produced as fine powders with enlarged surfaces. Furthermore, intercalation of solvent molecules in the pores of a MOF was investigated. It shows that the MOF adjustes its lattice paramters to the guest molecules. The potential to intercalate solid-state compounds is demonstrated using pharmaceutical drug molecules. Catalytic investigations show a good activity of the mechanochemically synthesized raw product.

Abstract:
Thermonuclear fusion may become an attractive future power source. The most promising of all fusion machine concepts is the tokamak. Despite decades of active research, still huge tasks remain before a fusion power plant can go online. One of these important tasks deals with the interaction between the fusion plasma and the reactor wall. This work focuses on how eroded wall materials of different origin and mass are transported in a tokamak device. Element transport can be examined by injection of certain species of unique and predetermined origin, so called tracers. Tracer experiments were conducted at the TEXTOR tokamak before its final shutdown. This offered an unique opportunity for studies of the wall and other internal components: For the first time it was possible to completely dismantle such a machine and analyse every single part of reactor wall, obtaining a detailed pattern of material migration. Main focus of this work is on the high-Z metals tungsten and molybdenum, which were introduced by WF6 and MoF6 injection into the TEXTOR tokamak in several material migration experiments. It is shown that Mo and W migrate in a similar way around the tokamak and that Mo can be used as tracer for W transport. It is further shown how other materials - medium-Z (Ni), low-Z (N-15 and F), fuel species (D) - migrate and get deposited. Finally, the outcome of dust sampling studies is discussed. It is shown that dust appearance and composition depends on origin, formation conditions and that it can originate even from remote systems like the NBI system. Furthermore, metal splashes and droplets have been found, some of them clearly indicating boiling processes.<br><p>QC 20151203</p>

Abstract:
Aquesta Tesi està dedicada a l’estudi de la interacció de la llum amb Polímers de Coordinació (CPs) i Xarxes Metalorgàniques (MOFs). S’ha seguit dos camins per aconseguir aquest objectiu; en primer lloc estudiant l’efecte fototèrmic observat en diferents subfamilies de MOFs, els quals, un cop irradiats amb llum UV‐Vis, presenten un escalfament local. Aquest augment de temperatura ha resultat útil tant en processos d’activació de MOFs com en Modificacions Covalents Post‐Sintètiques (CPSM). Per altra banda, sintetitzant nous CPs seguint l’estratègia de disseny de lligands fent servir complexos de coordinació de Ru2+‐terpiridines amb propietats de captació de llum. El Capítol 1 inclou una introducció general als CPs i MOFs, amb una visió històrica del seu descobriment i evolució, així com algunes de les múltiples aplicacions en les que aquests materials es poden implicar. En aquest sentit, ens hem centrat en les aplicacions que aprofiten la llum com a estímul extern. En el Capítol 2, hem resumit l’objectiu principal d’aquesta Tesi i n’hem detallat els objectius parcials. El Capítol 3 presenta una introducció als fonaments de la conversió de llum a calor en diferents materials. Alguns exemples de composites de MOFs, on les nanopartícules demostren un comportament fototèrmic, es troben resumits. Per altra banda també s’hi expliquen alguns dels mètodes més emprats per evacuar molècules que obstrueixen els porus de MOFs (activació). En aquest capítol es demostra que els MOFs també presenten efecte fototèrmic i que aquest efecte es pot utilitzar per a activar‐los eliminant les molècules de dissolvent un cop irradiats amb una làmpada UV‐Vis per temps curts. En el Capítol 4, la Modificació Post‐Sintètica (PSM) de MOFs es resumeix basant‐se en les interaccions entre l’esquelet del material porós i els agents modificants. També s’hi inclouen algunes estratègies alternatives per realitzar aquestes transformacions. En aquest sentit, l’ús de la calor local generada a partir de irradiar MOFs és utilitzada per aconseguir reaccions de CPSM. MOFs amb funcionalitzacions amino que presenten un fort efecte fototèrmic i anhídrids o aldehids es van mesclar (sense dissolvent) i la posterior exposició a llum UV‐Vis per temps curts va afavorir la fusió dels reactius i la reacció covalent. En el Capítol 5, les propietats d’absorció de llum i fototèrmiques d’alguns complexos organometàl∙lics s’exemplifiquen. També s’hi descriu l’estratègia beneficiosa de confinar aquests grups com a unitats estructurals en CPs i MOFs per a millorar la seva activitat. La síntesi i caracterització de tres nous CPs construïts a partir de complexos de Ru2+‐terpiridina i ions catalítics és descrita en aquest apartat. La caracterització fototèrmica d’aquests nous CPs demostra que presenten temperatures màximes en el rang dels MOFs amb un efecte fototèrmic més elevat. També es proposa realitzar un estudi dels CPs en reaccions de fotocatàlisi aprofitant la disposició dels complexes de Ru i dels ions metàl∙lics en els nodes.<br>This Thesis is devoted to the study of the interaction of light with Coordination Polymers (CPs) and Metal‐Organic Frameworks (MOFs). Two strategies have been followed to accomplish this objective. The first approach consisted on the study of the photothermal effect observed in different subfamilies of reported MOFs, which exhibited local heating upon UV‐Vis irradiation. Such temperature increase was proved useful for MOF activation and Covalent Post‐Synthetic Modification (CPSM) purposes. The second strategy was based on the synthesis of CPs following a ligand design approach using light‐harvesting Ru2+‐terpyridine complexes. Chapter 1 encloses a general introduction to CPs and MOFs, containing a historical overview of their discoveries and evolution, as well as some of the multiple applications in which these materials are involved. In this sense, we have focused on the applications arisen from the use of light as external stimulus. In Chapter 2, we have summarized the main objective of this Thesis and detailed the specific sub goals. Chapter 3 introduces the fundamentals of the light‐to‐heat conversion in different materials. Some examples of MOFs composites, where the nanoparticles exhibit the photothermal properties are reviewed. Moreover, a summary of some of the most common methods for removing guests from MOF pores (activation) is included. In this chapter, we demonstrate that MOFs also show photothermal effect and that this effect can be used to activate them by removing the solvent molecules after their irradiation with a UV‐Vis lamp for short periods. In Chapter 4, Post‐Synthetic Modification (PSM) of MOFs is reviewed based on the interactions between the framework and the desired modifying agents. To this end, some alternative strategies to perform such reactions are included. Thereafter, the use of the local heat generated upon MOF irradiation in CPSM reactions is reported. Amino‐tagged MOFs with strong photothermal effects and anhydrides or aldehydes were mixed (sovent‐free), and subsequent UV‐Vis exposure for short times allowed the melting of the reagents and the covalent reaction. In Chapter 5, the light‐harvesting and photothermal properties of some organometallic complexes are exemplified. The beneficial strategy of confining these moieties as building units in CPs and MOFs for enhancing their performance is described. The synthesis and characterization of three new CPs build up from Ru2+‐terpyridine complexes is reported here. Their photothermal characterization is performed and the new CPs showed maximum temperatures in the range of the MOFs with the strongest photothermal effect. In addition, future assessment of the CPs in photocatalytic reactions might be carried out, taking advantage of the close disposition of the Ru complexes and the metal ions of the nodes.

Abstract:
Zeolites are natural or synthetic materials with porous chemical structures that are valuable due to their absorptive and catalytic qualities. Metal-Organic Frameworks (MOFs) are manmade organometallic polymers with similar porous structures. This introductory book, with contributions from top-class researchers from all around the world, examines these materials and explains the different synthetic routes available to prepare zeolites and MOFs. The book also highlights how the substances are similar yet different and how they are used by science and industry in situations ranging from fueling cars to producing drugs.

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:
Metal-organic frameworks (MOFs) have recently attracted enormous interest over the past few years due to their potential applications in energy storage and gas separation. However, there have been few reports on MOFs for adsorption cooling applications. Adsorption cooling technology is an established alternative to mechanical vapor compression refrigeration systems. Adsorption cooling is an excellent alternative in industrial environments where waste heat is available. Applications also include hybrid systems, refrigeration, powerplant dry cooling, cryogenics, vehicular systems and building HVAC. Adsorption based cooling and refrigeration systems have several advantages including few moving parts and negligible power consumption. Key disadvantages include large thermal mass, bulkiness, complex controls, and low COP (0.2–0.5). We explored the use of metal organic frameworks that have very high mass loading and relatively low heats of adsorption, with certain combinations of refrigerants to demonstrate a new type of highly efficient adsorption chiller. An adsorption chiller based on MOFs suggests that a thermally-driven COP&gt;1 may be possible with these materials, which would represent a fundamental breakthrough in performance of adsorption chiller technology. Computational fluid dynamics combined with a system level lumped-parameter model have been used to project size and performance for chillers with a cooling capacity ranging from a few kW to several thousand kW. In addition, a cost model has been developed to project manufactured cost of entire systems. These systems rely on stacked micro/mini-scale architectures to enhance heat and mass transfer. Presented herein are computational and experimental results for hydrophyilic MOFs, fluorophilic MOFs and also flourophilic Covalent-organic frameworks (COFs).
