Abstract The microalgae Haematococcus pluvialis are the main source of natural antioxidant astaxanthin. However, effective extraction astaxanthin from these remains a significant challenge due to rigid, non-hydrolyzable cell walls. Energy savings and high-efficiency disruption essential steps in recovery cysts H. . In present study, were first cultured Bold's Basal medium under certain conditions reach maximum biomass concentration, then light shock was applied for accumulation. cells...
Gene therapeutics are promising for treating diseases at the genetic level, with some already validated clinical use. Recently, nanostructures have emerged targeted delivery of material. Nanomaterials, exhibiting advantageous properties such as a high surface-to-volume ratio, biocompatibility, facile functionalization, substantial loading capacity, and tunable physicochemical characteristics, recognized non-viral vectors in gene therapy applications. Despite progress, current exhibit notably...
Abstract In this work, intermolecular interactions among the species of fatty acids-based DESs with different hydrogen bond acceptors (HBA) in adjacent water have been investigated using molecular dynamics (MD) simulation. The results work provide deep insights into understanding stability based on thymol and eutectic mixtures choline chloride acids at a temperature 353.15 K atmospheric pressure. Stability, occupancy analysis, distribution HBA HBD around each other were attributed to alkyl...
Eyring's absolute rate theory was applied for evaluation of the viscosity ionic liquids (ILs) containing binary mixtures. Considering mathematical simplicity two-suffix-margules model, Gibbs energy model further modified. Furthermore, evaluation, proposed coupled with theory. To validate accuracy a large set data mixtures 122 ILs total number 5512 experimental points collected from literature. Moreover, average relative deviation (AARD %) obtained as 2.07 %. Also, capability Eyring–MTSM...
The objective of this study is to develop a model determine the thermal conductivity pure ionic liquids and ionanofluids. In order estimate liquids, group method data handling proposed based on 23 corresponding 216 experimental points. average absolute relative deviation for all studied systems was 1.79%, which satisfactory degree accuracy model. Furthermore, Maxwell modified correlate ionanofluids as function temperature volume fraction nanoparticles. 0.61%. Additionally, geometric mean...
Abstract In this work, we focused on the interaction between hydrogen bond acceptor (HBA) and doner (HBD) in binary mixtures. The results showed that Cl − anion plays a key role formation of DESs. Also, structural stability deep eutectic solvents based fatty acids (FAs) choline chloride (Ch + ) at different ratios was investigated water using molecular dynamics simulations. We observed hydroxyl group cation leads to transition HBA water-rich phase. These atomic sites have important rule...
Biallelic expansions of various tandem repeat sequence motifs are possible in RFC1 (replication factor C subunit 1), encoding the DNA replication/repair protein RFC1, yet only certain cause cerebellar ataxia, neuropathy, and vestibular areflexia syndrome (CANVAS). CANVAS presents enigmatic puzzles: The pathogenic path for neither is known nor it understood why some, but not all expanded, pathogenic. most common (AAGGG)n•(CCCTT)n, whereas (AAAAG)n•(CTTTT)n nonpathogenic motif. While both...
Wastewater treatment plants do not cope well with emerging micropollutants, such as pharmaceuticals, because they are effective to remove them. Therefore, this work aims develop a process for the extraction of ofloxacin (OFX) based on liquid-liquid using hydrophobic eutectic solvents (HES), coupled Conductor-like Screening Model Real Solvent (COSMO-RS) solvent screening. First, COSMO-RS was used predict partition coefficient OFX four HES families: L-menthol: fatty acid, alcohol, acid: acid...
Abstract The present study was conducted to develop a predictive type of PC-SAFT EOS by incorporating the COSMO computations. With proposed model, physical adjustable inputs were determined from suggested correlations with dependency computation results. Afterwards, we tested reliability modeling solubility data certain pharmaceutical compounds in pure and mixed solvents their octanol/water partition coefficients. obtained RMSE based on logarithmic scale for 1.435 all calculations. reported...
Saffron stigmas are considered as one of the main sources for crocin extraction. Crocins have many therapeutic properties and applications in different industries such food cosmetic which their extraction purification will be useful commercially clinically. This work presents a study on partitioning aqueous two-phase systems (ATPSs) composed water, deep eutectic solvents (DESs), acetonitrile (ACN). Two DESs based choline chloride hydrogen bond acceptor (HBA) urea ethylene glycol donors...
The enantioseparation of chiral drugs is a major challenge for the pharmaceutical industry as pharmacological activities enantiomers may differ, which can lead to severe secondary effects in treatment diseases. aim this study develop an platform resolution ofloxacin (OFX) using enantioselective liquid–liquid extraction (ELLE) based on hydrophobic eutectic solvent (HES) conjunction with one selector. β-Cyclodextrin (β-CD) derivatives, including β-CD, hydroxypropyl-β-cyclodextrin (HP-β-CD),...
In this study, the partitioning process of cephalexin antibiotic in aqueous two-phase systems (ATPS's) containing poly(ethylene glycol) (PEG) with molar masses (1500 and 6000) g·mol–1 sodium citrate salt has been measured. The experimental partition coefficients were measured at three temperatures: (298, 303, 308) K. effects temperature, polymer mass fraction, mass, fraction on coefficient also studied. results showed that a large effect temperature influence is almost negligible. data...
