Design and synthesis of novel amphipathic ionic liquids for biodiesel production from soapberry oil

Biodiesel produced from non-edible oils has received intensive attention in recent years. Herein, a series of novel amphipathic ionic liquids (ILs) based on the 4-dimethylaminopyridine (DMAP) were prepared for the transesterification of soapberry oil and methanol. The structures of the prepared ILs were systematically characterized by both Fourier transform infrared spectroscopy (FT-IR) and nuclear magnetic resonance (NMR, H-1 NMR and C-13 NMR). In addition, the effects of side-chain length of cation and the number of active site (H+) of ILs on the biodiesel yield were investigated, and the results suggested that 1-dodecyl-(4-dimethylammonium)-pyridinium bisulfate ([C12-DMAPH][HSO4](2)) exhibited the highest catalytic efficiency. Meanwhile, [C12-DMAPH][HSO4](2) was proven to be amphipathic, and the corresponding catalytic mechanism was proposed. Under the catalysis of [C12-DMAPH][HSO4](2), the optimum operating conditions of transesterification of soapberry oil and methanol were explored via the combination of single factor experiment and response surface methodology, obtaining the high biodiesel yield of (98.02 +/- 0.36)% under the optimum operating conditions. Importantly, [C12-DMAPH][HSO4](2) exhibited high stability in the transesterification of soapberry oil and methanol in five consecutive runs. Furthermore, the catalytic activities of [C12-DMAPH][HSO4](2) towards other transesterification of non edible oils and lower alcohols were also investigated, which indicated a general applicability of the prepared IL.

Diastereoselective Synthesis of Aryl C-Glycosides from Glycosyl Esters via C-O Bond Homolysis

C-aryl glycosyl compounds offer better in vivo stability relative to O- and N-glycoside analogues. C-aryl glycosides are extensively investigated as drug candidates and applied to chemical biology studies. Previously, C-aryl glycosides were derived from lactones, glycals, glycosyl stannanes, and halides, via methods displaying various limitations with respect to the scope, functional-group compatibility, and practicality. Challenges remain in the synthesis of C-aryl nucleosides and 2-deoxysugars from easily accessible carbohydrate precursors. Herein, we report a cross-coupling method to prepare C-aryl and heteroaryl glycosides, including nucleosides and 2-deoxysugars, from glycosyl esters and bromoarenes. Activation of the carbohydrate substrates leverages dihydropyridine (DHP) as an activating group followed by decarboxylation to generate a glycosyl radical via C-O bond homolysis. This strategy represents a new means to activate alcohols as a cross-coupling partner. The convenient preparation of glycosyl esters and their stability exemplifies the potential of this method in medicinal chemistry.

In Situ Formation of 3D Conductive and Cell-Laden Graphene Hydrogel for Electrically Regulating Cellular Behavior

Electroconductive and injectable hydrogels are attracting increasing attention owing to the needs of electrically induced regulation of cell behavior, tissue engineering of electroactive tissues, and achieving minimum invasiveness during tissue repair. In this study, a novel in situ formed 3D conductive and cell-laden hydrogel is developed, which can be broadly used in bioprinting, tissue engineering, neuroengineering etc. An instantaneous, uniform spatial distribution and encapsulation of cells can be achieved as a result of hydrogen bonding induced hydrogel formation. Particularly, the cell-laden hydrogel can be easily obtained by simply mixing and shaking the polydopamine (PDA) functionalized rGO (rGO-PDA) with polyvinyl alcohol (PVA) solution containing cells. Graphene oxide is reduced and functionalized by dopamine to restore the electrical conductivity, while simultaneously enhancing both hydrophilicity and biocompatibility of reduced graphene oxide. In vitro culture of PC12 cells within the cell-laden hydrogel demonstrates its biocompatibility, noncytotoxicity as well as the ability to support long-term cell growth and proliferation. Enhanced neuronal differentiation is also observed, both with and without electrical stimulation. Overall, this 3D conductive, cell-laden hydrogel holds great promise as potential platform for tissue engineering of electroactive tissues.

Effect of warm-air stream for solvent evaporation on bond strength of adhesive systems: A systematic review and meta-analysis of in vitro studies

Purpose: To determine whether warm-air stream for solvent evaporation improves immediate and long-term bond strength of adhesive systems through a systematic review and meta-analysis. Materials and methods: PubMed, ISI Web of Science, Cochrane Library, SciELO, Scopus, and BVS, as well as Open Grey, were searched for relevant studies. Only in vitro studies reporting the effect of the use of warm-air stream to evaporate solvents of adhesive systems on the bond strength to enamel or dentin, were included. A global analysis compared the standardized mean difference between bond strength values using warm-air stream against a control group in which room-temperature air-stream was used. Bond strength from etch-and-rinse and self-etch adhesives was analyzed separately using the random-effects model at a significance level of alpha = 0.05. For each adhesive type, subgroup analyses were performed considering the type of solvent with which the adhesives were formulated. Results: A total of 10 in vitro studies were included in the meta-analysis. For etch-and-rinse or self-etch adhesives, the use of warm-air stream for adhesive solvent evaporation improved the bond strength to dentin of wateror alcohol-based adhesive systems (p <= 0.03). On the contrary, this effect could not be observed for acetone-based adhesive systems (p >= 0.13). The overall effect demonstrated bond strength was enhanced with the use of warm-air stream (p <= 0.03). Conclusion: The in vitro evidence suggests that bond strength of self-etch or etch-and-rinse adhesives could be improved by using warm-air stream for solvent evaporation. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Effect of ethanol on the microstructure and rheological properties of whey proteins: Acid-induced cold gelation

The microstructure and mechanical properties of ethanol-denatured, acid-induced whey protein (WPI) cold-set gels have been monitored by confocal laser scanning microscopy and rheology. As the ethanol concentration increased, the porosity of the gels progressively decreased, with gels prepared at ethanol concentrations of 50 and 70 g/100 g lacking microscopically visible pores. Large aggregates were observed at ethanol concentrations of 70 g/100 g immediately after alcohol addition. A sharp increase in storage modulus was noted at ethanol concentrations between 30 and 50 g/100 g, while the gel strength at 50 g/100 g, was up to three times higher compared to that of heat-denatured gels. In general, the ethanol-denatured whey protein cold-set gels were prone to phase separation. Ethanol-denatured cold-set whey protein gels exhibited mechanical and microstructural properties that may offer alternative means of structuring protein-enriched food formulations and designing novel food products.

Nano SnO2 and Sb2O3 combined with CNTs as a high-capacity lithium storage material

The combination of Sb2O3 or SnO2 with graphene has become a research hotpot in recent years. However, several problems, namely the loading of the active materials, space utilization in composites, and the intrinsic volume expansion of Sb2O3 and SnO2, have yet to be fully resolved. To overcome these disadvantages, in this work Sb2O3/carbon nanotubes (CNTs)/SnO2 composite have been synthesized, in which the CNTs act as a network to ensure the electronic conductivity and buffer of the volume expansion. The SnO2 nanoparticles are aligned by the CNTs and Sb2O3 is dispersed in the voids between them. Space utilization and the loading of the oxides are thereby maximized. Moreover, the resultant composite retains small amount of water or alcohol, which does not affect the cyclic stability, but may have increased the ionic and electronic conductivity, improving the electrochemical performance. A discharge capacity of 910 mAh g(-1) after 250 cycles at 100 mA g(-1) is realized for Sb2O3/CNT/SnO2. Moreover, the contribution of the pseudocapacitance to the rate discharge capability is obvious, which arises from the different heterointerfaces between Sb2O3/CNTs, CNTs/SnO2 or Sb2O3/SnO2. The homogenous distribution of Sn and Sb in CNTs after cycling leads to a lower discharge voltage, improving the application prospects. Although some collapse and cracks are detected, the CNTs network connects the oxides, ensuring the structural stability and the cyclic stability of Sb2O3/CNT/SnO2. This strategy represents a new concept for the design of multi-component materials for lithium storage.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 3452-97-9, in my other articles.

MoS2 doping by atomic layer deposition of high-k dielectrics using alcohol as process oxidants

We developed doping technique of transition metal dichalcogenides based on atomic layer deposition (ALD) of oxide thin films. In this study, we deposited ALD Al2O3 overlayer using various oxidant including iso-propyl alcohol (IPA) and ethanol and investigated the doping effects depending on the choice of oxidant for ALD process. The doping effects were investigated by the change in the performance of bottom-gated MoS2 field effect transistors. Experimental results indicate that Al2O3 overlayer deposited using IPA as ALD reactant produces more efficient n-type doping effect compared to ethanol. Moreover, doping was effectively controlled by modulating atomic layer deposition process. ALD process using effective oxidant material is expected to be practically used for realizing the fabrication of threshold voltage-controllable transistors or further applications such as diodes.

How is intolerance of uncertainty related to negative affect in individuals with substance use disorders? The role of the inability to control behaviors when experiencing emotional distress

We used structural equation modeling to assess the role of impaired emotional awareness and clarity (Impaired Awareness/Clarity) and inability to control behaviors when experiencing emotional distress (Inability to Control Behaviors) as an account for the relationship between intolerance of uncertainty (IU) and negative affect (NA) in individuals with Substance Use Disorders (SUDs) and healthy controls (HCs) used for comparison. One-hundred and thirty-one individuals with SUDs (42.75% female; mean age = 39.74 11.83) and 131 sex matched HCs (mean age = 40.02 12.34) entered the study. Participants completed questionnaires assessing the constructs of interest. Single-group analyses aimed to identify a baseline model for each group and test the hypothesized direct/indirect relations’ overall significance. Then, a multigroup analysis tested the invariance of model parameters between SUD and HC groups. The model in which IU had both direct and indirect relationships with NA through Impaired Awareness/ Clarity and Inability to Control Behaviors was a good fit to the data. The indirect relationship of IU with NA through Inability to Control Behaviors was significant and moderate-sized. The relationship involving Impaired Awareness/Clarity and Inability to Control Behaviors was small-sized and significant in single group analysis only. The multigroup analysis supported the association of IU with NA through Inability to Control Behaviors in the SUD group. Overall, our study highlights the crucial role of the Inability to Control Behaviors in SUDs and suggests that its association with IU might fuel NA in this population.

In vitro biotransformation and evaluation of potential transformation products of chlorinated paraffins by high resolution accurate mass spectrometry

Chlorinated paraffins (CPs) are high production chemicals, which leads to their ubiquitous presence in the environment. To date, few studies have measured CPs in humans and typically at relatively low concentrations, despite indications that exposure may be high compared to various persistent organic pollutants. The aim of this study is to investigate the in vitro biotransformation of CPs by human liver fractions. We determined the changes of the CP concentrations after the enzymatic transformation with human liver microsomes using a two-tiered in vitro approach. CP concentrations decreased with human liver microsomes, with the decreases of 33-94% after incubating with different groups of enzymes for 2 h. The profiles of CP rapidly shifted after the incubation with human liver microsomes. In addition, the concentrations of CPs and the biotransformation products were tentatively measured using high-resolution mass spectrometric analysis, including very short CP (carbon chain length <10), alcohols, ketones, and carboxylic acids. C-C bond cleavage is a potential transformation pathway for CPs, and ketones are potential products of CP biotransformation, especially for long-chain CPs (C->17). The ketone products may be investigated as CP exposure biomarker in biomonitoring studies.
