Photoexcitation dynamics of p-nitroaniline (pNA) and N,N-dimethyl-p-nitroaniline (DMpNA) in 1-alkyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide ([Cnmim][NTf2]) with different alkyl chain lengths (from C2 to C12) was investigated using transient absorption spectroscopy. The internal conversion rate from the excited state to the ground state was estimated from bleach recovery around th...

Pseudomonas aeruginosa produces the quorum signal 2-heptyl-3-hydroxy-4-quinolone (Pseudomonas quinolone signal), which is important for stimulating outer membrane vesicle (MV) formation. Here we describe the importance of the 3-hydroxyl and 2-alkyl chain for MV production and the length of the 2-alkyl chain for association with MVs.

in recent years, ionic liquids have been used in pharmaceutical processes. therefore, having a deep insight into the ion association behavior of ionic liquids in the presence of a drug is of particular importance. so, in this work, the molar conductivities of the ionic liquids, 1-alkyl-3-methylimidazolium bromide, [cnmim]br (n = 4, 6 and 8) in various concentrations of aspirin (asa) in acetonit...

We found that ethyl gallate purified from a dried pod of tara (Caesalpinia spinosa) intensified beta-lactam susceptibility in methicillin-resistant and methicillin-sensitive strains of Staphylococcus aureus (MRSA and MSSA strains, respectively). This compound and several known alkyl gallates were tested with MRSA and MSSA strains to gain new insights into their structural functions in relation ...

Aiming at providing a comprehensive study of the influence of the cation symmetry and alkyl side chain length on the surface tension and surface organization of ionic liquids (ILs), this work addresses the experimental measurements of the surface tension of two extended series of ILs, namely R,R'-dialkylimidazolium bis[(trifluoromethyl)sulfonyl]imide ([C(n)C(n)im][NTf2]) and R-alkyl-3-methylimi...

Self-assembled layers of alkyl chains grafted onto the surfaces of layered silicates, metal, and oxidic nanoparticles are utilized to control interactions with external media by tuning the packing density of the chains on the surface, head group functionality, and chain length. Characterization through experiment and simulation shows that the orientation of the alkyl layers and reversible phase...

The influence of alcohols with different alkyl chain length (methanol, ethanol and propanol) on the physicochemical properties (turbidity, surface hydrophobicity, exposed total free sulfhydryl ...
