In-depth physico-chemical and structural investigation of dicarboxylic acid/choline chloride NaDES: a spotlight on the importance of a rigorous preparation procedure

In this study, we report the density, viscosity, conductivity, and X-ray diffraction profile of the deep eutectic solvent (DES) formed by choline chloride and different dicarboxylic acids (i.e., malonic, oxalic, succinic, or fumaric acid) at room temperature. These compounds have recently found several applications in green chemistry methodologies and consequently require the highest purity standards.

Effect of an enzymatic treatment with cellulase and mannanase on the structural properties of Nannochloropsis microalgae

The effects of an enzymatic treatment with cellulase and mannanase on the properties of marine microalgae
Nannochloropsis sp. were investigated. The combined use of these enzymes synergistically promoted the recovery
of lipids from the microalgae, increasing the extraction yield from 40.8 to over 73%. Untreated and enzymatically
treated microalgae were characterized by chemical analysis and by TGA/DTG, FTIR, XRD and SEM.
Significant changes were observed in the chemical composition and thermal behavior of the microalgae. The

Complexation of halide ions to tyrosine: role of non-covalent interactions evidenced by IRMPD spectroscopy

The binding motifs in the halide adducts with tyrosine ([Tyr + X]-, X = Cl, Br, I) have been investigated
and compared with the analogues with 3-nitrotyrosine (nitroTyr), a biomarker of protein nitration, in a
solvent-free environment by mass-selected infrared multiple photon dissociation (IRMPD) spectroscopy
over two IR frequency ranges, namely 950–1950 and 2800–3700 cm-1. Extensive quantum chemical
calculations at B3LYP, B3LYP-D3 and MP2 levels of theory have been performed using the 6-311++G(d,p)
