Gold(I) NHC Complexes: Antiproliferative Activity, Cellular Uptake, Inhibition of Mammalian and Bacterial Thioredoxin Reductases, and Gram‐Positive Directed Antibacterial Effects
Claudia Schmidt,Bianka Karge,Rainer Misgeld,Aram Prokop,Raimo Franke,Mark Brönstrup,Ingo Ott +6 more
TL;DR: Gold complexes with N-heterocyclic carbene (NHC) ligands represent a promising class of metallodrugs for the treatment of cancer or infectious diseases, and antibacterial screening of the gold complexes showed a particularly high activity against Gram-positive strains, reflecting their high dependence on an intact Trx/TrxR system.

Performance of PEMFC with new polyvinyl-ionic liquids based membranes as electrolytes
TL;DR: In this paper, two different types of membranes based on protic ionic liquids have been tested in PEMFC under anhydrous conditions, i.e., Nafion membranes impregnated with 1-methyl-3-(4-sulfobutyl)-imidazolium bis(trifluoromethylsulfonyl)-imide ([HSO3-BMIm][NTf2]) and 1-butyl-3(4-Sulfobuthyl)-inhibyl-imidaxolium trif

Novel Brønsted Acidic Ionic Liquids and Their Use as Dual Solvent−Catalysts
Amanda C. Cole,Jessica L. Jensen,Ioanna Ntai,Kim Loan T. Tran,Kristin J. Weaver,David C. Forbes,James H. Davis +6 more
TL;DR: The new ionic liquids combine the low volatility and ease of separation from product normally associated with solid acid catalysts, with the higher activity and yields normally found using conventional liquid acids.

Energetic Salts of 3-Nitro-1,2,4-triazole-5-one, 5-Nitroaminotetrazole, and Other Nitro-Substituted Azoles†
TL;DR: In this paper, the structure of 3-amino-1,2,4-triazolium 3-nitro-5-trifluoromethyl-1.2, 4.4, 5.5, and 5.nitroimino-tetrazolate anions were characterized using the computationally feasible DFT(B3LYP) and MP2 methods.

Electrophilic nitration of aromatics in ionic liquid solvents.
TL;DR: Ionic liquid nitration is a useful alternative to classical nitration routes due to easier product isolation and recovery of the ionic liquid solvent, and because it avoids problems associated with neutralization of large quantities of strong acid.

Stickstoffreiche energetische Salze und ionische Flüssigkeiten
TL;DR: In this paper, die Verwendung von stickstoffhaltigen Kationen und Anionen tragt zu hoheren Bildungswarmen und Dichten bei, wobei durch den niedrigen Gehalt an Kohlenstoff und Wasserstoff auch eine gute Sauerstoffbilanz erzielt wird.
