The post-synthetic inclusion of two luminescent cationic modules into a blue-emitting metal-organic framework (MOF) leads to a trichromatic white-light-emitting composite. When it is exposed to specific volatile organic solvents, nitroaromatic and metal ion solutes, the two MOF ligand-to-module peak-emission ratios undergo analyte- and quantity-dependent changes, leading to 2- and 3D ratiometric luminescent sensing with high selectivity and sensitivity. More information can be found in the Full Paper by J.-J. Zhang, H. Zhou, J. Ni, et al. on page 9555.

"Cr-keeper" nanoparticles (CKN) are in-situ synthesized based on the challenge of separation trace vanadium (V) from chromium (VI) in aqueous solution. Kelp is used as the bio-template and it can react with chromium (VI). Transmission electron microscopy (TEM) results reveal that CKN can copy the cell structure from kelp and the specific surface area of CKN is 343.20 m(2)/g. Fourier transform infrared (FT-IR) and X-ray photoelectron spectroscopy (XPS) analysis confirm the formation of hydroxyl and Cr (III) species in CKN. The adsorption capacity of V (V) onto CKN is 51.20 mg/g and the maximum separation coefficient (beta(V/Cr) = 3900) is achieved at pH 3.00. The adsorption kinetics follow pseudo-first-order model and Weber-Morris intra particle diffusion model. The adsorption isotherms follow the Sips model. The regeneration and reusability of CKN are discussed. All the results suggest that the utilization of biomass's cell structure as the template for the fabrication of adsorbent with "Cr-keeper" function is excellent, which will bring new directions for Cr (VI) system purification.

A self-driven microbial fuel cell (MFC) - microbial electrolysis cell (MEC) system, where electricity generated from MFCs is in situ utilized for powering MECs, has been previously reported for recovering Cr(VI), Cu(II) and Cd(II) with individual metals fed in different units of the system in batch operation. Here it was advanced with treating synthetic mixed metals' solution at appropriately adjusting composites in fed-batch and continuous flow operations for complete separation of Cr(VI), Cu(II) and Cd(II) from each other. Under an optimal condition of hydraulic residence time of 4h, matching of two serially connected MFCs with one MEC, and fed with a composite of either 5mgL(-1) Cr(VI), 1mgL(-1) Cu(II) and 5mgL(-1) Cd(II), or 1mgL(-1) Cr(VI), 5mgL(-1) Cu(II) and 5mgL(-1) Cd(II), the self-driven MFC-MEC system can completely and sequentially recover Cu(II), Cr(VI) and Cd(II) from mixed metals. This study provides a true sustainable and zero-energy-consumed approach of using bioelectrochemical systems for completely recovering and separating Cr(VI), Cu(II) and Cd(II) from each other or from wastes or contaminated sites.
