Identification and quantification of bipyridyl dicarboxylic acid isomers by ion mobility spectrometry.

The identification of positional isomers is of interest because different isomers have different chemical or biological functions and applications. The analysis of positional isomers is sometimes challenging since they have similar chemical structures and properties. For example, the analysis of mass cannot identify different positional isomers because they have identical mass-to-charge ratios and show a single mass peak in mass spectrometry.

Self-assembled core-shell clusters in deep eutectic solvents based on tetra-n-alkylammonium cations for high dissolution of strongly hydrogen-bonded small molecules.

Strongly hydrogen-bonded compounds such as 1,3,5-triamino-2,4,6‑trinitrobenzene (TATB, an important insensitive high explosive) have excellent stability, but poor solubilities to limit their recrystallization, purification and recycling. In this study, core-shell clusters based on symmetrical tetra-n-alkylammonium [TTA] are designed to provide an inner cavity to incorporate TATB, and thus the clusters can separate TATB from original hydrogen-bonded networks to increase largely the solubility. Based on this design, deep eutectic solvents (DESs) based on [TTA] cations are first developed to yield self-assembled core-shell clusters for solubilizing TATB.

Double-edged role of interlayer water on Li extraction from ultrahigh Mg/Li ratio brines using Li/Al-LDHs.

Lithium-aluminum layered double hydroxides (Li/Al-LDHs) are the only industrial adsorbents for Li extraction from Mg/Li ratio brines dependent on the special neutral desorption without dissolution damage. In this work, Li/Al-LDHs with different interlayer water contents were designed for the investigation of correlation between interlayer water and Li adsorption performances in high Mg/Li ratio brines. On the one hand, the Li adsorption capacity of Li/Al-LDHs in the Qarham Salt Lake old brine with a Mg/Li ratio exceeding 300 presented a positive correlative relation with the interlayer water content, rising from 1.

Supramolecular-induced 2.40 V 130 °C working-temperature-range supercapacitor aqueous electrolyte of lithium bis(trifluoromethanesulfonyl) imide in dimethyl sulfoxide-water.

Increasing the electrochemical stability window and working temperature range of supercapacitor aqueous electrolyte is the major task in order to advance aqueous electrolyte-based supercapacitors. Here, a supramolecular induced new electrolyte of lithium bis(trifluoromethanesulfonyl) imide (LiTFSI) in dimethyl sulfoxide (DMSO) and water co-solvent system is proposed. Adjusting the coordination structure among LiTFSI, DMSO, and water in the electrolyte via supramolecular interactions results in its high ionic conductivity, low viscosity, wide electrochemical stability window, and large working temperature range.

Mechanism and therapeutic prospect of resveratrol combined with TRAIL in the treatment of renal cell carcinoma.

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has been reported to kill a wide variety of tumor cells with minimal effects on normal cell. However, renal cell carcinoma (RCC) cells 786-0 and OS-RC-2 were resistant to TRAIL. The present study examines the potential of combining polyphenolic compound resveratrol (RES) with TRAIL.

Induction and Suppression of Innate Antiviral Responses by Hepatitis A Virus.

Hepatitis A virus (HAV) belongs to the family . It is the pathogen of acute viral hepatitis caused by fecal-oral transmission. RNA viruses are sensed by pathogen-associated pattern recognition receptors (PRRs) such as Toll-like receptor 3 (TLR3), retinoic acid-inducible gene I (RIG-I), and melanoma differentiation-associated gene 5 (MDA5).
