New materials spur new technologies. Nanoporous metalorganic materials — “soft materials”analogues of zeolites, but with all of the chemical diversity of carbon compounds — may be compelling examples of this path from materials to technologies. Research teams investigating this new class of materials are trying to develop adsorbents and membranes that will revolutionize small-molecule separatio...
Uncontrolled massive release of the primary greenhouse gas carbon dioxide (CO2) into atmosphere from anthropogenic activities poses a big threat and adversely affects our global climate and natural environment. One promising approach to mitigate CO2 emission is carbon capture and storage (CCS), in which ideal adsorbent materials with high storage capacity and excellent adsorption selectivity ov...
The rich diversity and complexity of organic matter found in meteorites is rapidly expanding our knowledge and understanding of extreme environments from which the early solar system emerged and evolved. Here, we report the discovery of a hitherto unknown chemical class, dihydroxymagnesium carboxylates [(OH)2MgO2CR]-, in meteoritic soluble organic matter. High collision energies, which are requ...
We report the self-assembly of core–shell GeTe/Sb2Te3 nanowires (NWs) on Si (100), and SiO2/Si substrates by metalorganic chemical vapour deposition, coupled to vapour–liquid–solid mechanism, catalyzed Au nanoparticles. Scanning electron microscopy, X-ray diffraction, micro-Raman mapping, high-resolution transmission energy loss spectroscopy were employed investigate morphology, structure, comp...
