From ZIF-8@Al2O3Composites to Self-Supported ZIF-8 One-Dimensional Superstructures

Efficient preparation of composite materials consisting of ZIF-8 nanocrystals embedded inside the channels of macroporous anodic aluminum oxide membranes is reported. 1-D self-supported ZIF-8 superstructures are recovered through matrix dissolution

Here’s looking at the reduction of noninnocent copper corroles via anion induced electron transfer

The synthesis, electrochemical and spectroscopic characterization of five copper triarylcorroles bearing one, two or three meso-nitroaryl substituents is reported. Redox potentials and spectroscopic properties of the neutral Cu(II) corrole cation radicals and singly reduced form of the complexes are reported in $\mathrm{CH}_{2}\mathrm{Cl}_{2}$ and the ability of the initial noninnocent derivatives to be chemically reduced via anion induced electron transfer (AIET) is explored using cyanide ($\mathrm{CN}^{-}$) or fluoride ($\mathrm{F}^{-}$) anions in the form of tetra-$n$-butylammonium salts. UV–visible spectra of the singly reduced corroles and the species generated after addition of $\mathrm{CN}^{-}$ or $\mathrm{F}^{-}$ to solutions of the neutral compounds are identical, thus confirming the AIET event in these systems. This result, when combined with the facile electrochemical reduction, provides strong indirect evidence for the presence of noninnocence in these systems

Porous materials applied to biomarker sensing in exhaled breath for monitoring and detecting non-invasive pathologies

International audienceOverview of the use of porous materials for gas sensing to analyze the exhaled breath of patients for disease identification.The quantification of specific gases among thousand of VOCs (Volatile Organic Compounds) present in the human breath at the ppm/ppb level can be used to evidence the presence of diseases in the human body. The detection of these biomarkers in human exhaled breath through a noninvasive approach is an important field of research which is still attracting important attention to this day. A portable device working at room temperature and usable directly on exhaled breath samples is still a challenge requiring a sensing material with high performances. The rich composition of the human breath implies that the sensing material must be highly selective and sensitive (ppm/ppb) in high relative humidity (RH) conditions and preferably at room temperature. The present work intends to provide a review on recent works in this application field through the use of porous materials and discuss the interest of Metal Organic Frameworks (MOFs) for such application. MOFs are highly porous crystalline materials often used for gas detection and capture, thus raising the question of their potential for detection in exhaled breath
