Fluorescent Zn(II)-Based Metal-Organic Framework: Interaction with Organic Solvents and CO and Methane Capture.

Adsorption of carbon dioxide (CO), as well as many other kinds of small molecules, is of importance for industrial and sensing applications. Metal-organic framework (MOF)-based adsorbents are spotlighted for such applications. An essential for MOF adsorbent application is a simple and easy fabrication process, preferably from a cheap, sustainable, and environmentally friendly ligand.

Intracellular Ionic Strength Sensing Using NanoLuc.

Intracellular ionic strength regulates myriad cellular processes that are fundamental to cellular survival and proliferation, including protein activity, aggregation, phase separation, and cell volume. It could be altered by changes in the activity of cellular signaling pathways, such as those that impact the activity of membrane-localized ion channels or by alterations in the microenvironmental osmolarity. Therefore, there is a demand for the development of sensitive tools for real-time monitoring of intracellular ionic strength.

Single crystal structure, vibrational spectroscopy, gas sorption and antimicrobial properties of a new inorganic acidic diphosphates material (NH)Mg(HPO)•2HO.

We report on the successful synthesis of diammonium magnesium dihydrogendiphosphate (V) dihydrate compound (NH)Mg(HPO)•2HO using a wet chemical route. Single crystal X-ray diffraction analysis and micro Raman spectroscopy are employed to characterize the compound. We demonstrate, using a multidisciplinary approach, that this compound is ideal for carbon dioxide (CO) capture in addition to other anthropogenic gasses.

Quantum Chemistry Insight into the Interactions Between Deep Eutectic Solvents and SO.

A systematic research work on the rational design of task specific Deep Eutectic Solvents (DES) has been carried out via density functional theory (DFT) in order to increase knowledge on the key interaction parameters related to efficient SO capture by DES at a molecular level. A total of 11 different DES structures, for which high SO affinity and solubility is expected, have been selected in this work. SO interactions in selected DES were investigated in detail through DFT simulations and this work has generated a valuable set of information about required factors at the molecular level to provide high SO solubility in DES, which is crucial for enhancing the current efficiency of the SO capture process and replacing the current state of the art with environmentally friendly solvents and eventually implementing these materials in the chemical industry.

Toxicity evaluation of selected ionic liquid compounds on embryonic development of Zebrafish.

Hydrate formation in seafloor pipelines is considered an economic and flow assurance issue for the oil and gas industries. Ionic liquids (ILs) have been recently used as potential hydrate inhibitors. Although branded as green compounds, their ecotoxicity in case of leakage from pipelines onto the aquatic environment needs more deep evaluations.

Viscosity mixing rules for binary systems containing one ionic liquid.

In this work the applicability of four of the most commonly used viscosity mixing rules to [ionic liquid (IL)+molecular solvent (MS)] systems is assessed. More than one hundred (IL+MS) binary mixtures were selected from the literature to test the viscosity mixing rules proposed by 1) Hind (Hi), 2) Grunberg and Nissan (G-N), 3) Herric (He) and 4) Katti and Chaudhri (K-C). The analyses were performed by estimating the average (absolute or relative) deviations, AADs and ARDs, between the available experimental data and the predicted ideal mixture viscosity values obtained by means of each rule.
