Example 1 – Deoxydehyd ration of 1,2-decanediol In the following examples, unless something else is stated, 40 mmol of diol, 2.0 mmol of catalyst (5 mol%, calculated with respect to the amount of vanadium), 500 mg of hexadecane (internal standard), and 100 ml of solvent were mixed in a 300 ml PTFE cup and placed in a 400 ml autoclave with a magnetic stir bar and computer-controlled heating plate. The autoclave was sealed, pressurized with 10-25 bar of H2, N2, or CO and heated to 230 C for 1000 min (corresponding to ~ 16 h at the reaction temperature); the temperature typically stabilized between 225 and 235 C. When the system had cooled to room temperature, the pressure was released, the reaction mixture was filtered to remove a black precipitate and analyzed by GC (for determination of conversion and yields) and GC-MS (for observation and identification of other products). Comparison of solvents A number of primary or secondary monohydric Ci-Cio alcohol solvents were tested together with NH4V03 as the catalyst. In addition, their performance was compared to that of acetone and hexane as solvents. The yields of 1-decene (C=C), 2-decanone (C=0), 2-decanol (2OH), and 1-decanol (lOH) are provided below in Table 1. It is evident that using a primary or secondary monohydric Ci-Cio alcohol as the solvent results in a better selectivity of 1-decene than any of the comparative solvents.

General procedure: All experiments to test the catalytic activity were performed in a Schlenk tube (50mL vol.) attached to a condenser. The catalytic activity was evaluated for HDO oxidation in basic aqueous media with H2O2 as oxidant to obtain HCA. In a typical reaction procedure, aliphatic diol (0.5mmol) and catalyst (25mg) were weighed and dispersed in deionized water (3.5mL) in a Schenk tube. 30% H2O2 (0.75mL) and 0.5M NaOH (0.75mL) were added to the above mixture, and then the Schlenk tube was mounted on a preheated oil bath at 353K. The mixture was allowed to react for various time intervals with continuous magnetic stirring (500 rpm). After the reaction, a part of the resultant solution was diluted 20 times with an aqueous H2SO4 (10mM) solution, and the catalyst was filtered off using a 0.20mum filter (Milex-LG). The obtained filtrate was analyzed by high performance liquid chromatography (HPLC, WATERS 600) using an Aminex HPX-87H column (Bio-Rad Laboratories, Inc.) attached to a refractive index detector. An aqueous 10mM H2SO4 solution (eluent) was run through the column (maintained at 323K) at a flow rate of 0.5mLmin-1. The conversion and yield(s) were determined with a calibration curve method using commercial products.

This study examined associations of self-regulatory behavior and cognitive functioning with substance use (SU) to inform interventions for youth with perinatal HIV infection (YPHIV) or exposure but uninfected (YPHEU). Youth aged 7-15 years (YPHIV, n = 390; YPHEU, n = 211) were followed longitudinally with cognitive testing and behavioral questionnaires including self-report of alcohol, marijuana, tobacco, and other SU. Cox proportional hazards analyses were used to examine correlates of initiating each substance for those without prior use at baseline and generalized estimating equation analyses were used to address associations of cognitive/behavioral measurements with SU prevalence for the entire sample. Lower self-reported self-regulation skills, but higher cognitive functioning abilities, were associated with initiation and prevalent use of alcohol and marijuana regardless of HIV status. Our findings suggest SU screening tools and self-regulation interventions developed for general adolescent populations should be implemented for those with PHIV, who may be at heightened risk for SU-related health consequences.

Enhanced flux and fouling resistance forward osmosis membrane based on a hydrogel/MOF hybrid selective layer

Although forward osmosis (FO) technology has been widely adopted for water treatment, it still faces great challenges, including low permeability and fouling problem. Herein, a novel forward osmosis membrane was developed with a stable, uniform and defect-free polyvinyl alcohol/polydopamine coated zeolitic imidazolate framework (PVA/PDA@ZIF-8) hybrid selective layer to simultaneously enhance its transport property and fouling resistance. The prepared FO membrane exhibits improved water flux without losing the selectivity, since the PDA@ZIF-8 provide additional preferential passageway for water transporting while hinder the diffusion of salt. The optimized membrane shows a higher water flux than pristine PVA membrane (14.2 vs. 8.7 L m(-2) h(-1) in FO mode, 24.3 vs. 14.8 L m(-2) h(-1) in PRO mode) with a reasonable selectivity considering as J(s)/J(w) value (0.44 vs. 0.4 g L-1 in FO mode, 0.38 vs. 0.33 g L-1). Moreover, the dynamic fouling experiments with organic foulants (protein and polysaccharide) indicate that the prepared membrane exhibits strong antifouling property and excellent permeation recovery ability (>95.0%) due to the optimized surface property. This study opens a new avenue for treatment wastewater by developing a forward osmosis membrane based on a hydrogel/MOF hybrid selective layer. (C) 2020 Elsevier Inc. All rights reserved.

Production and characterization of shape memory polymeric nanocomposite materials

Polymers are macromolecular materials that simple molecules (monomers) come together with chemical bonds and form them. The industrial use area of polymers is increasing due to many advantages of them such as mechanical properties, easy formability, lightweight, and low cost. Properties of smart (capable of reacting to an external effect) polymers; because of external effects such as magnetic field, electric field, temperature, and pH, they can change their shape and various mechanical properties. Areas such as aviation, construction, electronics, and medical can be given as examples to the usage areas of such materials. In this study, poly (vinyl alcohol) (PVA) polymer was used as a matrix in nanocomposite materials. New types of shape memory nanocomposites materials were obtained by using reduced graphene oxide (rGO) and graphene oxide (GO) produced by the Hummers method as fillers. Differential scanning calorimeter (DSC) and thermogravimetric analysis (TGA) devices were used to examine the thermal characterization of materials. X-ray diffraction (XRD) method and Fourier transform infrared spectrometry (FT-IR) were used for structural characterization analysis. In addition, chemical characterization of the materials was investigated using energy diffusion X-ray analysis (EDX) and surface morphology using scanning electron microscopy (SEM). The shape memory performances of the produced nanocomposite materials were determined by the shape recycling tests. It is examined the effect of fillers on the shape memory performance, structural and thermal properties of nanocomposite materials. (C) 2020 Elsevier B.V. All rights reserved.

Ultrasonic effects on the headspace volatilome and protein isolate microstructure of duck liver, as well as their potential correlation mechanism

In spite of the high added value and tremendous output from duck processing industries, duck liver (DLv) is underutilized and a major factor is related to its prominent off-flavor perception which hampers the consumption and processing attributes. This work was designed to investigate the impact of low-frequency ultrasound (US) pretreatments on the headspace volatilome evolution of DLv and its isolated protein (DLvP) microstructure, aiming at exploring the potential of US technology to inhibit off-flavor perception and possible mechanisms behind. Results suggested that US pretreatment resulted in decreased lipid oxidation and off-flavor perception, simultaneously without significantly causing physicochemical influence including texture, pH and color. US induced obvious tertiary structural changes of DLvP, as revealed by the intrinsic fluorescence and surface hydrophobicity (H0), whereas the SH, S-S, secondary structure and molecular weight of DLvP remained unaffected, suggesting the presence of molten globule state (MG-state) under ultrasonic conditions. Besides, the headspace contents of flavor compounds, mainly aldehydes and alcohols, were significantly decreased whereas acids were increased. Multivariate analysis suggested an obvious US-induced effect on the volatilome evolution of DLv samples. Discriminant analysis recognized the aroma compounds including aldehydes and alkenals as the major contributors leading to the change of olfactory characteristics of DLv after ultrasonic treatment. Correlation analysis demonstrated the positive relationship between the volatile markers variation and the increased H0 values, a characteristic attribute of MG-state protein. The results obtained in this work suggested that US technology matched with suitable parameters could be a very promising approach to modulate the off-flavor perception of liver products by altering DLvP conformation.

Solubility determination, model evaluation, Hansen solubility parameter and thermodynamic properties of benflumetol in pure alcohol and ester solvents

The equilibrium solubility and thermodynamic properties of benflumetol in methanol, ethanol, npropanol, n-butanol, n-pentanol, n-hexanol, n-heptanol, n-octanol, methyl acetate, ethyl acetate, n-propyl acetate, n-butyl acetate and n-pentyl acetate were reported. Solubility determinations were performed through the laser monitoring method at T = (278.15-323.15) K and p = 101.3 kPa. It is found that the mole fraction solubility of benflumetol increases apparently with the augmented experimental temperature. In addition, the solubility of benflumetol in all ester solvents is greater than that in alcohol solvents. The maximum mole fraction solubility of benflumetol is obtained in n-pentyl acetate (4.061 x 10(-2), T = 323.15 K), and the minimum mole fraction solubility of benflumetol is obtained in methanol (1.341 x 10(-5), T = 278.15 K). The Hansen solubility parameter for benflumetol as well as selected solvents was summarized to analyse the probabilities of miscibility between solute and solvents. The analysis consequence shows that the miscibility of benflumetol with selected solvents is caused by a combination of factors. All recorded solubility of benflumetol were regressed by 9.11 model, modified Apleblat model, two-Suffix Margules model, NRTL model and UNIQUAC model. By comparison, it can be found that the average ARD and 10 4 RMSD of the modified Apelblat model and NRTL model are smaller than the other three models, indicating that these two moedls are more suitable for correlating the solubility data. In addition, the apparent thermodynamic properties of benflumetol in all neat solvents were calculated and investigated by the Van’t Hoff equation. The results illustrated that the dissolution process of benflumetol is an entropy-driven endothermic process. (C) 2020 Elsevier Ltd.

Preparation of 3D Printed Chitosan/Polyvinyl Alcohol Double Network Hydrogel Scaffolds

In this work, a 3D printed double-network (DN) hydrogel scaffold is designed with chitosan (CS) and polyvinyl alcohol (PVA) as the framework matrix. The addition of PVA into the CS-based hydrogel clearly enhances the mechanical properties and lowers the swelling behaviors of the hydrogels. The crosslinking of CS with genipin can perform the pre-crosslinking to improve the viscosity and 3D printability of the hydrogel precursor, while increasing the PVA content results in lowering the viscosity and 3D printability of the pre-crosslinked hydrogel. The antibacterial property results of the DN hydrogel display that the hydrogel have favorable long-lasting antibacterial ability. The appropriate pre-crosslinked hydrogel with the CS/PVA mass ratio of 3:10 and pre-crosslinking time of 7 h is used for 3D printing to prepare the 3D printed porous DN hydrogels. Moreover, the anti-tumor drug doxorubicin (DOX) is loaded into the 3D printed porous DN hydrogels and the in vitro release study displays the sustainable drug release behavior. And the DOX release from hydrogel scaffold can be adjusted by the pH value of release environment. All of the results indicate that the porous DN CS/PVA hydrogel scaffolds have great application potential for tissue regeneration.
