Key features of the deep eutectic solvent-microwave assisted simultaneous extraction polyphenols and delignification pretreatment chestnut shell waste are presented.
The full utilization of agricultural waste and its recycle into a new chain value are primary importance for the development sustainable profitable industry. Chestnut shell (CSW) is an interesting case study, whose valorization has been though partially investigated to date. This work aims at exploring complete CSW, in terms obtaining both value-added compounds enriched cellulose lignin fractions. results were obtained via unreported combined use two classes nonconventional organic solvents,...
The objective of this study was to examine the bioactivity extracts from apple pomace obtained by non-conventional green extraction methods (DES systems). Bioactivity antioxidant capacity and ability stimulate insulin secretion pancreatic beta-cells. examined using DPPH FRAP assay. Impact on cell viability were BRIN-BD11 line. ChCl:EG(1:4) resulted in high assay (80.1% inhibition versus 11.3%). Extracts classical systems demonstrated an promote significantly higher than positive control, p <...
In this study, the efficacy of two best performing green solvents for fractionation lignocellulosic biomass, cholinium arginate (ChArg) as biobased ionic liquid (Bio-IL) and ChCl:lactic acid (ChCl:LA, 1:10) natural deep eutectic solvent (NADES), was investigated compared in pretreatment an agri-food industry waste, apple fibers (90°C 1 h). For sake comparison, 1-butyl-3-methylimidazolium acetate (BMIM OAc) one IL able to dissolve cellulose also used. After pretreatment, fractions were...
The antipsychotic drug olanzapine is well known for its complex polymorphism. Although widely investigated, the crystal structure of one anhydrous polymorphs, form III, still unknown. Its appearance, always in concomitance with forms II and I, impossibility isolating it from that mixture, have prevented determination so far. scenario has changed emerging field 3D electron diffraction (3D ED) great advantages characterization polyphasic mixtures nanosized crystals. In this study, we show how...
The crystal structure of GaP nanowires grown by Au-assisted chemical beam epitaxy was investigated as a function group V flux and growth temperature. By increasing the tertiarybutyl phosphine we obtained with stacking defect-free wurtzite structure. Variation temperature also had profound impact on Lowering from 600 to 560 °C keeping constant both triethylgallium precursor fluxes, NWs drastically improved highly defective intergrowth zinc-blende free defects. These results are compared...
Raman measurements are performed on defect-free wurzite GaP nanowires. Resonance carried out over the excitation energy range between 2.19 and 2.71 eV. Resonances at 2.38 eV 2.67 of E1(LO) mode A1(LO) observed. The presence these intensity resonances clearly demonstrates existence states with Gamma_9hh Gamma_7V (Gamma_7C) symmetries valence (conduction) band allows to measure WZ phase energies Gamma point. In addition, we have investigated temperature dependent resonant measurements, which...
We report on the demonstration of Terahertz (THz) broadband detectors based field effect transistors exploiting tapered semiconductor nanowires. The intrinsic asymmetry provided by nanowires geometry allows to achieve responsivity values as high 55 V/W (2.5 mA/W) and a noise-equivalent-power 3 × 10−10 W/Hz1/2 independent specific gate voltage applied. possibility reduce number terminals required source drain contacts only technological feasibility multi-pixel arrays are promising for...
A chiral ionic liquid with a natural alcohol based chain was used as tailoring agent for the synthesis of simple and cost effective materials such ZnO, CuO, CuO–ZnO peculiar morphology.

The polymorphism of oxyresveratrol, a natural extract widely used in traditional Asian medicine, was investigated by means the most recent structure characterization techniques. A previously unknown anhydrate oxyresveratrol crystal identified for first time from submicrometric polyphasic mixture using 3D electron diffraction (3D ED). Additionally, new polymorph dihydrate form also discovered and structurally studied. Detailed thermal calorimetry studies revealed their behavior dehydration...
Abstract Selective and potent matrix metalloproteinase 12 (MMP‐12) inhibitors endowed with improved hydrophilicity are highly sought for potential use in the treatment of lung cardiovascular diseases. In present paper, we modified structure a nanomolar MMP‐12 inhibitor by incorporating an ionic liquid (IL) moiety to improve aqueous solubility. Four biologically active salts were obtained linking sulfonamide imidazolium‐, pyrrolidinium‐, piperidinium‐, DABCO‐based ILs. The imidazolium‐based...
Abstract Layered double hydroxides, containing Mg or Zn as divalent cations in the brucite - like layer and derived mixed oxides obtained after calcination process of clays have been used to remove anionic surfactant, sodium dodecylbenzenesulfonate, from aqueous solutions. The property layered clay reconstruct its structure by using structural "memory effect" has a controlled variable parameter during adsorption/ intercalation processes tested surfactant. extent dodecylbenzenesulfonate...
