Extraction of caffeine using aqueous two-phase systems containing ionic liquid and sorbitol

In this study, a new aqueous two-phase system consisting of tetrabutylphosphonium bromide ionic liquid and sorbitol was selected. The partitioning of caffeine as a substance having many applications in the food and pharmaceutical industries was evaluated in this system. The effect of the variables such as the weight percentages of the ionic liquid and carbohydrate on the partitioning of caffeine was shown. The results indicated that by increasing the ionic liquid weight fraction and the sorbitol weight fraction, the partition coefficient of caffeine increased. Nevertheless, in all stages, the caffeine had a tendency to migrate towards the ionic liquid-rich phase. Also, the results indicated that the temperature had not an effect on the partitioning of caffeine. The recovery percentage of caffeine was reported in this system. The experimental results of the partition coefficient of caffeine were fitted by different regression models, and the most efficient regression model was selected based on the statistical analysis.

One-Carbon Incorporation Using Cyclobutanone Oxime Ester Enabled [2+2+1] Carboannulation of 1,7-Enynes by C-C/N-O Bond Cleavage and C-H Functionalization

A NiCl2-promoted [2 + 2 + 1] carboannulation of 1,7-enynes with internally oxidative cyclobutanone oximes to produce canyo-functionalized 4H-cyclopenta[c]quinolin-4-ones is disclosed. Through C-C/N-O bond cleavage and C-H functionalization, the process enables one-carbon incorporation using cyclobutanone oximes to achieve [2 + 2 + 1] carboannulation of 1,7-enynes, which is highlighted by allowing the formation of four new bonds with high selectivity and broad substrate scope.

Carboxyboronate as a Versatile In Situ CO Surrogate in Palladium-Catalyzed Carbonylative Transformations

The application of carboxy-MIDA-boronate (MIDA=N-methyliminodiacetic acid) as an in situ CO surrogate for various palladium-catalyzed transformations is described. Carboxy-MIDA-boronate was previously shown to be a bench-stable boron-containing building block for the synthesis of borylated heterocycles. The present study demonstrates that, in addition to its utility as a precursor to heterocycle synthesis, carboxy-MIDA-boronate is an excellent in situ CO surrogate that is tolerant of reactive functionalities such as amines, alcohols, and carbon-based nucleophiles. Its wide functional-group compatibility is highlighted in the palladium-catalyzed aminocarbonylation, alkoxycarbonylation, carbonylative Sonogashira coupling, and carbonylative Suzuki-Miyaura coupling of aryl halides. A variety of amides, esters, (hetero)aromatic ynones, and bis(hetero)aryl ketones were synthesized in good-to-excellent yields in a one-pot fashion.

Recent Advances in Experimental Measurements of Mixed-Gas Three-Phase Hydrate Equilibria for Gas Mixture Separation and Energy-Related Applications

Clathrate hydrates are currently studied extensively due to their involvement in important industrial processes. For certain industrial applications (e.g., flow assurance in oil/gas industry), they are considered a nuisance and their presence needs to be either suspended completely or adequately controlled. On the other hand, for other industrial applications (e.g., gas mixture separation, water desalination, and purification), hydrate formation is sought after, since it can facilitate the desired outcome. In either case, it is essential to have reliable values for the hydrate equilibrium conditions, in order to design appropriately the corresponding industrial applications. In the current study, we review the experimental studies that have reported three-phase hydrate equilibrium measurements. We focus primarily on studies that were published after the year 2008. Furthermore, we report only studies that examine the gas mixtures of two or more components. Of primary interest are gas mixtures that have significant industrial applications and include components such as carbon dioxide, nitrogen, hydrogen, methane, ethane, propane, hydrogen sulfide, and oxygen. The examined mixtures include at least one of the aforementioned gases. Of particular interest in this review are applications such as gas mixture separation (where hydrate promotion is desirable) and energy-related application such as flow assurance during oil/gas production and transportation (where hydrate inhibition is desirable). The mixtures that are included in the review are grouped under 15 gas mixture types. For most of the gas mixtures that are examined, the related industrial applications are identified and briefly discussed. In the current review, the different gas mixtures are also critically discussed and suggestions for possible future directions are presented regarding the examination of tentative additives to be used for promotion or inhibition.

Surfactant-based selective assembly approach for Si-embedded silicon oxycarbide composite materials in lithium-ion batteries

High-capacity silicon anode materials have attracted significant attention for application in lithium-ion batteries (LIBs), even though the drastic volumetric changes of the silicon materials result in rapid capacity degradation. Here, an Si-embedded silicon oxycarbide (SiOC) was synthesized using a selective assembly-based method. We utilized cetrimonium bromide (CTAB), a cationic surfactant, to facilitate interfacial interactions between Si nanoparticles and silicone oil using the hydrophobic property of the CTAB tail groups. The synthesis method includes a simple pyrolysis process at 900 degrees C followed by the surface modification of Si nanoparticles with the CTAB surfactant to obtain a SiOC matrix with homogeneously embedded Si particles. The final composite exhibits improved electrochemical properties as a LIB anode material and displays a stable cycle life (1312 mAh.g(-1) for the 100th cycle at 0.5 A.g(-1)) in addition to enhanced power characteristics (634 mAh.g(-1) at the high current density of 5 A.g(-1)). The SiOC matrix effectively suppressed the volumetric change of the inner Si particles in addition to enhancing the conductivity due to the free carbon in SiOC materials.

Radial basis function artificial neural network (RBF ANN) as well as the hybrid method of RBF ANN and grey relational analysis able to well predict trihalomethanes levels in tap water

Many models have been developed in previous studies for predicting the formation of disinfection by-products (DBPs) in drinking water. However, most of them were linear or log-linear regression models, and generated based on simulated disinfection of source water or treated water in a laboratory other than real tap water, which shows low application potential in practice. In this study, a radial basis function artificial neural network (RBF ANN) as well as the hybrid method of RBF ANN and grey relational analysis (GRA) was proposed to predict trihalomethanes (THMs) levels in real distribution systems. A total of 64 sets of data including THM5 levels (trichloromethane (TCM), bromodichloromethane (BDCM) and total-THMs (T-THMs)) and 8 water quality parameters (temperature, pH, UV absorbance at 254 (UVA(254)), dissolved organic carbon, bromide, residual free chlorine, nitrite and ammonia) were used to train and verify the proposed model. As compared to linear and log-linear regression models (r(p) = 0.254-0.659; N-25 = 46-78%), RBF ANN5 for THM5 (TCM, BDCM and T-THMs) prediction consistently show higher regression coefficients (r(p) = 0.760-0.925) and prediction accuracy (N-25 = 92-98%), which indicates the high capability of RBF ANN to learn the complex non-linear relationships involved THM5 formation. Further analysis shows that RBF ANN5 using fewer water quality parameters based on GRA still make excellent performance in THM5 prediction (r(p) = 0.760-0.946; N-25 = 92-98%). This result demonstrates that GRA can be an effective technique to facilitate the generation of sound RBF ANN models with fewer factors.

Study on Hydrolysis of Magnesium Hydride by Interface Control

Magnesium hydride (MgH2) is one of the competitive hydrogen storage materials on account of abundant reserves and high hydrogen content. The hydrolysis of MgH2 is an ideal and controllable chemical hydrogen generation process. However, the hydrolyzed product of MgH2 is a passivation layer on the surface of the magnesium hydride, which will make the reaction continuity worse and reduce the rate of hydrogen release. In this work, hydrogen generation is controllably achieved by regulating the change of the surface tension value in the hydrolysis, a variety of surfactants were systematically investigated for the effect of the hydrolysis of MgH2 In the meantime, the passivation layer of MgH2 was observed by scanning electron microscope (SEM), and the surface tension value of the solution with different surfactants were monitored, investing the mechanism of hydrolysis adding different surfactants. Results show that different surfactants have different effects on hydrogen generation. The hydrogen generation capacity from high to low is as follows: tetrapropylammonium bromide (TPABr), sodium dodecyl benzene sulfonate (SDBS), Ecosol 507, octadecyl trimethyl ammonium chloride (OTAC), sodium alcohol ether sulfate (AES), and fatty methyl ester sulfonate (FMES-70). When the ratio of MgH2 to TPABr was 5 : 1, the hydrogen generation was increased by 52% and 28.3%, respectively, at the time of 100 s and 300 s. When hydrolysis time exceeds 80 s, the hydrogen generation with AES and FMES-70 began to decrease; it was reduced by more than 20% at the time of 300 s. SEM reveals that surfactants can affect the crystalline arrangement of Mg(OH)(2) and make the passivation layer three-dimensionally layered providing channels for H2O molecules to react with MgH2.

Combined experimental and theoretical investigations of Ba3GaS4I: interesting structural transformation originated from halogen substitution

Inorganic chalcohalides have emerged as promising functional materials for a range of applications. However, most of them are chlorides and bromides, while iodides are still rare. Herein, a new quaternary iodine-based chalcohalide Ba3GaS4I has been acquired by the reaction of BaS, Ga, S and BaI2 at 1173 K. Single-crystal XRD analysis reveals that Ba3GaS4I has a centrosymmetric structure (orthorhombic, space group Cmcm, a = 6.991(3) angstrom, b = 15.910(7) angstrom, c = 9.698(4) angstrom, V = 1078.6(7) angstrom(3), and Z = 4) and consists of isolated [GaS4] tetrahedra with charge-balanced Ba2+ cations and I- anions. Ba3GaS4I can be regarded as the product of chemical substitution of Ba3GaS4X (X = Cl, Br), which adopts a different space group, Pnma. The influences of the halogen elements on the bandgap and birefringence have been discussed through first principles calculations and structural comparison.

From Proteomics to Personalized Medicine: The Importance of Isoflavone Dose and Estrogen Receptor Status in Breast Cancer Cells

Continuing efforts are directed towards finding alternative breast cancer chemotherapeutics, with improved safety and efficacy profiles. Soy isoflavones represent promising agents but, despite extensive research, limited information exists regarding their impact on the breast cancer cell proteome. The purpose of this study was to compare the proteomic profiles of MCF-7 (estrogen responsive) and MDA-MB-231 (estrogen non-responsive) breast cancer cells exposed to different concentrations of genistein, daidzein, and a soy seed extract, using a high throughput LC-UDMSE protein profiling approach. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay confirmed the dual activity of soy isoflavones on MCF-7 cells and the inhibitory effect on MDA-MB-231 cells. Proteome profiling of paramagnetic beads prepared peptides by nano-LC UDMSE and pathway enrichment analysis revealed that isoflavones affected distinct molecular pathways in MCF-7 and MDA-MB-231 cells, such as tyrosine kinases signaling pathway, cytoskeleton organization, lipid and phospholipid catabolism, extracellular matrix degradation and mRNA splicing. Also, in MCF-7 cells, low and high isoflavone doses induced different changes of the proteome, including cell cycle alterations. Therefore, the expression of estrogen receptors and the isoflavone dose are determinant factors for the molecular impact of isoflavones and must be taken into account when considering adjuvant breast cancer therapy towards personalized medicine.
