AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Metal org. frameworks (MOFs) are cryst. materials that contain metal-ions or metal-ion clusters as nodes and org. ligands as linkers to form 1-, 2-, and 3-D structures. In addn. to their convenient modular synthesis and chem. tunability, this class of mate ...
A thorough experimental and computational study has been carried out to elucidate the mechanistic reasons for the high volumetric uptake of methane in the metal-organic framework Cu-3(btc)(2) (btc(3-) = 1,3,5-benzenetricarboxylate; HKUST-1). Methane adsorp ...
Hydrogen is often regarded as a viable clean burning alternative to our current petroleum based fuel sources as a result of its high gravimetric energy d. and renewable nature. Furthermore, H2 has received significant attention as a transportation fuel. A ...
Owing to their high surface areas, tunable pore dimensions, and adjustable surface functionality, metal-org. frameworks (MOFs) can offer advantages for a variety of gas storage and gas sepn. applications. In an effort to help curb greenhouse gas emissions ...
The main difference between the past energy economy during the industrialization period which was mainly based on mining of fossil fuels, e.g. coal, oil and methane and the future energy economy based on renewable energy is the requirement for storage of t ...
An energy economy based on renewable energy requires massive energy storage, approx. half of the annual energy consumption. Therefore, the production of a synthetic energy carrier, e.g. hydrogen, is necessary. The hydrogen cycle, i.e. production of hydroge ...
Owing to their high surface areas, tunable pore dimensions, and adjustable surface functionality, metal-org. frameworks (MOFs) can offer advantages for a variety of gas storage and gas sepn. applications. In an effort to help curb greenhouse gas emissions ...
Molecular simulations and NMR relaxometry experiments demonstrate that pure benzene or xylene confined in isoreticular metal-organic frameworks (IRMOFs) exhibit true vapor-liquid phase equilibria where the effective critical point may be reduced by tuning ...
The metal-org. frameworks M2(dobdc) (dobdc4- = 2,5-dioxido-1,4-benzenedicarboxylate, MOF-74, CPO-27) (M = Mg, Mn, Fe, Co, Ni, Zn) have shown considerable promise for a no. of gas storage and sepn. applications. These have included CO2/N2, CO2/H2, O2/N2, an ...
This paper studies about metal-org. frameworks for on-board storage of hydrogen and natural gas. The paper studies on synthesis of thermally-robust, high-surface area materials with a high concn. of open metal coordination sites. ...
