this paper is the first multi-scale characterization of the fluidize-dried gum extracted from the fresh fruits of the plant abelmoschus esculentus. it describes the physical, thermal, sorptional and functional properties of this natural gum. elemental analysis, scanning electron microscopy (sem), particle size analysis, x-ray powder diffraction (xprd), thermo-gravimetric analysis (tga), differe...

The synthesis and successful activation of IRMOF-8 (Zn(4)O(ndc)(3), ndc = naphthalene-2,6-dicarboxylate) is presented. Room temperature synthesis effectively suppresses interpenetration. Although conventional activation under reduced pressure leads to structural collapse, activation by flowing supercritical CO(2) yields a guest-free material with a BET surface area of 4461 m(2) g(-1).

A Proton Transfer Reaction-Mass Spectrometer (PTR-MS) has been coupled to the outlet of a Field and Laboratory Emission Cell (FLEC), to measure volatile organic compounds (VOC) concentration during a sorption experiments (Rizk et al., this issue) [1]. The limits of detection of the PTR-MS for three VOCs are presented for different time resolution (2, 10 and 20 s). The mass transfer coefficient ...

Poly(4-vinylpyridine), 4VP, resins cross-linked with oligo(ethylene glycol dimethacrylates) were used for chelating resins. Sorption for some metal ions by complexation in acetate buffer (pH 3-6) was investigated mainly by using the 4VP resins cross-linked with hydrophilic tetraethylene glycol dimethacrylate (4VP-4EG) and that cross-linked with hydrophobic divinylbenzene (4VP-DVB). The differen...

Odor information is first represented as a spatial activation pattern across the olfactory epithelium, when odor is drawn into the nose through breathing. This epithelial pattern likely results from both the intrinsic olfactory sensory neuron (OSN) sensitivity and the sorptive patterns imposed by the interaction of nasal aerodynamics with physiochemical properties of odorants, although the prec...

The article provides an overview of the literature on the role of sorption detoxification using intestinal adsorbents (enterosorption method) in the multifaceted treatment of various diseases. The mechanism of action of adsorbents and their therapeutic effects are presented. We emphasized that intestinal adsorbent Enterosgel is a modern, effective, and safe detoxifying agent.

Many metal-organic frameworks are water labile, including the iconic Hong-Kong University of Science and Technology-1 (HKUST-1). Spray-dry encapsulation of HKUST-1 crystals into polystyrene microspheres is reported here to yield composites that are resistant to water but retain most of the excellent gas sorption capacity of HKUST-1. These composites are demonstrated to exhibit superior water ad...

IRMOF-3 nano/microcrystals with controllable morphologies and sizes were successfully obtained by a simple solvothermal method. The shape evolution of IRMOF-3 crystals from cube to truncated cube, cuboctahedron, truncated octahedron and finally to octahedron was achieved by adjusting the amount of surfactant. The surfaces of the IRMOF-3 nano/microstructures are affected by the reaction temperat...
