摘要： The present invention relates, inter alia, to the use of porous crystalline solids constituted of a metal-organic framework (MOF) for the capture of polar volatile organic compounds (VOCs). In particular, the MOF of interest are material comprising an average pores sizes of 0.4 to 0.6 nm and an hydrophobic core formed by a metal oxide and/or hydroxide network connected by linkers, said linkers being selected from the group comprising (i) C6-C24 aromatic polycarboxylate linkers, such as benzyl or naphtyl di-, tri- or tetracarboxylate, and (ii) C6-C16 polycarboxylate aliphatic linkers; the linkers bearing or not apolar fluorinated groups, e.g. —(CF2)n—CF3 groups, n being a integer from 0 to 5, preferably 0 ou 3, and/or apolar C1-C20 preferably C1-C4 alkyl groups, e.g. —CH3 or —CH2—CH3, grafted directly to the linkers and pointing within the pores of the MOF. The MOF solids used in the present invention can be used for the purification of air, for example for the capture of polar VOCs like acetic acid and aldehydes from indoor air in cars, museums and archives, much more efficiently than common adsorbents, particularly in presence of above normal levels of humidity. They can in particular be used for the preservation of cultural heritage.

摘要： The present invention relates to the use of 2,5-furanedicarboxylate-based MOFs, such as, MIL-160(Al) metal-organic framework, for separating C6 alkane isomers into linear, mono-branched and di-branched isomers. The present invention also relates to the use of 2,5-furanedicarboxylate-based MOFs, such as, MIL-160(Al) metal-organic framework, preferably in combination with Zeolite 5A for producing higher research octane number gasoline blends. Also within the scope of the invention is a system for separating C6 and C5 alkane isomer mixtures into linear, mono-branched and di-branched fractions.

摘要： A device for phase microscopy is disclosed that comprises a spatial light modulator and a connecting means adapted to fix the spatial light modulator onto a phase microscope. The phase microscope comprises a light path comprising at least a sample area, a light device for lighting said sample area, and an imaging device for capturing a phase image of said sample area. The phase image is a 2D matrix of pixels. The spatial light modulator is positioned in the light path in a conjugated plane of the sample area. The device also comprises a command of the spatial light modulator connected to the imaging device and adapted to measure the phase shift of a plurality of pixels of the phase image and to command the spatial light modulator in order to subtract the measured phase shifts.

摘要： The present invention relates, inter alia, to the use of porous crystalline solids constituted of a metal-organic framework (MOF) for the selective adsorption of aldehyde volatile organic compounds.
The MOF solids of the present invention can be used for the improved purification of dry or humid air, and for the manufacture of regenerable filters for air purification, particularly leak-free regenerable air filters.
