    ABSTRACT: In this study, the combustion behaviors of sludge–biomass mixed pellets with different sludge ratios in air atmosphere were investigated by thermogravimetric analysis. The pellets consisted of sludge and Chinese fir or rice straw with sludge ratios of 0%, 25%, 50%, 75% and 100%, respectively. The thermogravimetric data were applied for kinetic analysis using the Coats and Redfern (CR) equation. Results showed that there were four main stages such as dehydration, volatile oxidation, char burning and burnout during thermal decomposition of pellets. The reactivities of sludge–biomass pellets were improved by the increment of the mixing ratio of biomass. In addition, the potential slagging behaviors of the resultant ashes were evaluated by X-ray fluorescence (XRF). The suitable sludge to biomass ratio should consider the combustion properties and ash slagging deposition of pellets. It is inappropriate for the production of sludge–straw pellet in the present state due to the high ash slagging potential.

    ABSTRACT: The improvement on the co-pelletization of biomass (cedarwood and camphorwood) and oil cake was carried out in the present work. The characteristics of raw materials were determined by chemical and physical analysis. The cp-pelletization process was studied by quantifying the energy consumption of compaction and extrusion. The physical properties of pellets including moisture adsorption, pellet energy density and hardness were also determined. It was shown that the blending of biomass with oil cake would increase the density of pellets, and thus reduce their costs during production, transport and storage. The energy consumption of compaction decreased with the increasing content of castor bean cake, while the energy consumption of extrusion and pellets’ energy density had an opposite tendency. Moreover, the maximum compression force and hardness increased with the blend ratio of CAS (castor bean cake) rising. This thermal analysis suggests that adding CAS can enhance char combustion and lead to more reactivity during char combustion. 10-20% of castor bean cake would be a suitable proportion in the co-pelletization with biomass in terms of energy consumption and pellet properties.

    ABSTRACT: In recent years, tremendous research efforts have been made towards developing metal–organic framework (MOF)-based composites for photocatalytic applications. In this work, bipyramid-like MIL-125(Ti) frustum enwrapped with reduced graphene oxide (rGO) and dispersed silver nanoparticles (Ag NPs) was fabricated using an efficient one-pot self-assembly and photoreduction strategy. The as-obtained materials were characterized using field emission scanning electron microscopy, transmission electron microscopy, X-ray diffraction, nitrogen adsorption–desorption isotherms, and X-ray photoelectron, ultraviolet–visible diffuse reflectance and photoluminescence spectroscopies. It is found that the as-prepared Ag/rGO/MIL-125(Ti) ternary hybrids have large surface area, microporous structure, enhanced visible light absorption and prolonged lifetime of charge carriers. Compared with pure MIL-125(Ti) and its binary counterparts, the ternary composite exhibits more efficient photocatalytic performance for Rhodamine B (RhB) degradation from water under visible light irradiation. The photodegradation rate of RhB on Ag/rGO/MIL-125(Ti) is 0.0644 min−1, which is 1.62 times higher than that of the pure MIL-125(Ti). The improved photocatalytic performance is ascribed to the indirect dye photosensitization, the Ag NP localized surface plasmon resonance, the Ti3+–Ti4+ intervalence electron transfer and the synergistic effect among MIL-125(Ti), Ag NPs and rGO. Ag NPs serve as an efficient ‘electron reservoir’ and rGO as an electron transporter and collector. Therefore, this work provides a new pathway into the design of MOF-based composites for application in environmental and energy fields. Copyright

    ABSTRACT: The pyrolysis characteristics and kinetics of the blends produced from the mixture of torrefied camphorwood and caster bean cake (CAS) were determined by thermogravimetric analysis. Kissenger–Akahira–Sunose (KAS) and Coats–Redferm methods were applied for kinetic analysis. The results show that torrefaction can increase the maximum decomposition rate and smooth the pyrolysis reaction at 250–330 °C in the differential thermogravimetry (DTG) curves, and the additive of CAS can reduce the high maximum decomposition rate caused by torrefaction. The kinetic results suggest that the activation energy can be enhanced by torrefaction, while this can be lowered by the additive of CAS. It was found that the activation energy dropped dramatically for CAM torrefied at 300 °C by Coats–Redferm method, whereas KAS method showed the contrary trend. The pre-exponential factors by Coats–Redferm method were decreased by the processes of torrefaction and co-pelletization with CAS. In consideration of heating value and activation energy, 270 °C torrefaction and 30% CAS is conservatively selected as the optimum condition.

    ABSTRACT: Seismic-induced pounding between adjacent structures that are insufficiently separated can cause significant structural damage, even collapse, during severe earthquakes. This paper presents an experimental and numerical investigation into mitigating pounding on highway bridges using novel shape memory alloy pseudo-rubber shock-absorbing devices (SMAPR-SADs). The mechanical properties and a theoretical model of SMAPR-SADs are briefly introduced and investigated. Next, a series of shaking table tests on a 1:30 model of a steel highway bridge are conducted to investigate the effectiveness of the SMAPR-SADs in mitigating the pounding of the structures. Based on the experimental results, the pounding-induced stress waves are analyzed using wave theory and the cross-wavelet transform method. Subsequently, numerical models of highway bridges with and without SMAPR-SADs are proposed. The pounding mitigation mechanism of SMAPR-SADs is analyzed using the momentum theorem, their ability to dissipate energy, and stress wave absorption theory. Two indexes representing the energy absorption and dissipation abilities of SMAPR-SADs are proposed and investigated. Finally, the effect of the axial stiffness of SMAPR-SADs on pounding mitigation is analyzed. The experimental and theoretical results demonstrate that SMAPR-SADs are able to absorb energy stably and can significantly reduce the pounding response of highway bridges under seismic excitations.

    ABSTRACT: Generalized anxiety disorder (GAD) and panic disorder (PD) are most common anxiety disorders with high lifetime prevalence while the pathophysiology and disease-specific alterations still remain largely unclear. Few studies have taken a whole-brain perspective in the functional connectivity (FC) analysis of these two disorders in resting state. It limits the ability to identify regionally and psychopathologically specific network abnormalities with their subsequent use as diagnostic marker and novel treatment strategy. The whole brain FC using a novel FC metric was compared, that is, scaled correlation, which they demonstrated to be a reliable FC statistics, but have higher statistical power in two-sample t-test of whole brain FC analysis. About 21 GAD and 18 PD patients were compared with 22 matched control subjects during resting-state, respectively. It was found that GAD patients demonstrated increased FC between hippocampus/parahippocampus and fusiform gyrus among the most significantly changed FC, while PD was mainly associated with greater FC between somatosensory cortex and thalamus. Besides such regional specificity, it was observed that psychopathological specificity in that the disrupted FC pattern in PD and GAD correlated with their respective symptom severity. The findings suggested that the increased FC between hippocampus/parahippocampus and fusiform gyrus in GAD were mainly associated with a fear generalization related neural circuit, while the greater FC between somatosensory cortex and thalamus in PD were more likely linked to interoceptive processing. Due to the observed regional and psychopathological specificity, their findings bear important clinical implications for the potential treatment strategy.

    ABSTRACT: This study aimed to prepare and characterize the inclusion complex between posaconazole (POS) and hydroxypropyl-β-cyclodextrin (HP-β-CD). Phase solubility study was conducted to investigate the drug/CD interaction in solution, including the stoichiometry and apparent stability constant. The solid complex (HP-β-CD–POS) obtained was characterized through Fourier transform infrared spectroscopy, powder X-ray diffraction, 1H and ROESY 2D nuclear magnetic resonance, differential scanning calorimetry, and scanning electron microscopy. These approaches confirmed the formation of the inclusion complex. The HP-β-CD–POS inclusion complex exhibited better water solubility and higher dissolution rate than the free POS did; the water solubility of POS was increased by 82 times and almost 90% of the loaded drug dissolved after 10 min in the dissolution media. In addition, preliminary in vitro antifungal susceptibility testing revealed that HP-β-CD–POS maintains a high level of antifungal activities. Therefore, the HP-β-CD complex may be useful in the delivery of posaconazole.

    ABSTRACT: 3D ultralight graphene metamaterial (GM) with large negative Poisson's ratio and superelasticity was fabricated by a modified hydrothermal approach and subsequent oriented freeze-casting strategy. By controlling growth orientation of ice crystals, this GM presents a unique hyperbolic pattern and hierarchical honeycomb-like scaffold in microstructure. The curvature of hyperbolic pattern can be adjusted by changing macroscopic aspect ratio (L/D) of the bulk configuration. Uniaxial compression experiments demonstrate that the Poisson's ratio of GM is tunable over a wide range, from positive to negative values by adjusting the structural porosity, L/D and freeze- casting conditions. The GM fabricated in a non-contact freeze-casting process with L/D = 1.1 presents the largest negative Poisson's ratio due to the orthogonally patterned hyperbolic microstructure. The evolution and strain mapping of the GM microstructure during compression are characterized by in situ observation via SEM to reveal the fundamental mechanism of its negative Poisson's ratio response. Benefiting from the negative Poisson's ratio, well-interconnected scaffolds, and strong π-π interactions among graphene sheets, such GM exhibits superelasticity and tremendous mechanical robustness with ultralarge reversible compressibility (up to 99%), suggesting a promising applicability to technologies including soft actuators, strain sensors, robust shock absorbers and environmental remediation.

    ABSTRACT: The interaction of norgestrel with human serum albumin (HSA) was investigated by spectroscopy and molecular-docking methods. Results of spectroscopy methods suggested that the quenching mechanism of norgestrel on HSA was static quenching and that the quenching process was spontaneous. Negative values of thermodynamic parameters (ΔG, ΔH, and ΔS) indicated that hydrogen bonding and van der Waals forces dominated the binding between norgestrel and HSA. Three-dimensional fluorescence spectrum and circular dichroism spectrum showed that the HSA structure was slightly changed by norgestrel. Norgestrel mainly bound with Sudlow site I based on a probe study, as confirmed by molecular-docking results. Competition among similar structures indicated that ethisterone and norethisterone affected the binding of norgestrel with HSA. CH3 in R1 had little effect on norgestrel binding with HSA. The surface hydrophobicity properties of HSA, investigated using 8-anilino-1-naphthalenesulfonic acid, was changed with norgestrel addition.

    ABSTRACT: The interaction of drospirenone (DP) with human serum albumin (HSA)/lysozyme (LYZ) was investigated using different optical techniques and molecular models. Results from the emission and time resolved fluorescence studies revealed that HSA/LYZ emission quenching with DP was initiated by static quenching mechanism. The LYZ-DP system was more easily influenced by temperature than the HSA-DP system. Displacement experiments demonstrated that the DP binding site was mainly located in site 1 of HSA. Based on the docking methods, DP was mainly bound in the active site hinge region where Trp-62 and Trp-63 are located. Conformation study showed that DP had different effects on the local conformation of HSA and LYZ molecules.

    ABSTRACT: UV-visible-shortwave near infrared diffuse reflectance spectroscopy (UV-vis-SWNIR DRS) combined with chemometrics are firstly investigated to discriminate enantiomers and their racemic compounds, using D-, L- and DL-alanine as model compounds. After optimizing the measuring conditions of powder particle sizes and distance between fiber probe and sample, discriminant partial least squares (PLS-DA) models were built with UV-vis-SWNIR DRS to implement the qualitative analysis of alanine chirality. As a result, under the optimized conditions of particle size sifted through 100-mesh and distance of 5.3 mm, an excellent discrimination of chirality with an accuracy of 100% which is better than that of manufacturers with an accuracy of 86.67% were obtained. The results of this study infer that UV-vis-SWNIR DRS combined with chemometrics can be a rapid, simple and noninvasive method for chiral analysis.

    ABSTRACT: A carbon nano-fiber based conductive polymer (CNFP) film was fabricated by multi-scale carbon nano-fibers (10 ~ 200 nm) an in-situ filtrating casting process, due to the well-connected hierarchical microstructures and strong-wrapped assembling among carbon nano-fibers, the as-prepared CNFP presents excellent electrical conductivity, high thermo-electric performance and good mechanical properties. And the resistivity of the CNFP exhibited piecewise linear temperature-dependent characteristics within a certain temperature range (0 ~ 280 °C). Furthermore, based on excellent electric and thermo-electric properties, CNFP was employed as electric heating element to develop a novel self-deicing road system. This CNFP-based deicing system is consisted of CNFP as thermal source, an AlN-ceramic insulated encapsulation layer, a multiwall carbon nanotube (MWCNT)/cement-based thermal conduction layer and a thermally insulated substrate. Additionally, the MWCNT/cement-based composite, which was filled with 3% by weight MWCNT, was proposed as the thermal conduction layer because its thermal conduction properties are superior to those of cement with other fillers and to those of common cement-based composites. To ensure the efficient operation of the CNFP, an AlN-ceramic wafer (0.5 mm) was employed as the electro-insulated layer because of its favorable insulating and thermo-conductive properties. The constructed system was applied in deicing and field snow-thawing studies, in which the effects of ambient temperature, heat flux density and ice thickness on the deicing and snow-thawing performance of the self-deicing system were investigated. The efficiency, repeatability, cost and feasibility of the self-deicing road system in both deicing and snow-thawing applications were analyzed. Indices for evaluating the deicing or snow-thawing performance of the self-deicing road system were proposed and the optimal values for each parameter are presented. The results demonstrate the promise of CNFP as heating element of self-heating pavement on a wide application in deicing or snow-thawing for infrastructures, including pavement, highway, airport and bridge.

    ABSTRACT: An improved microemulsion electrokinetic chromatography (MEEKC) method for the simultaneous determination of seven caffeoylquinic acids (CQAs) in honeysuckle-related products was reported. Multiple additives significantly affected the separation of CQA isomers, but adding 20 mmol L−1 chiral potassium sodium tartrate most significantly improved the separation and enabled short analysis time (within 22 min). The results indicated that tartrate could be an alternative additive for the rapid separation and quantification of CQA isomers. A low-pH phosphate buffer (pH 2.25) was also used to maintain the stability of CQA and suppress electroosmotic flow. Three monoCQA and four diCQA achieved good baseline separation under the optimal conditions. The limits of detection (S/N = 3) and limits of quantitation (S/N = 10) ranged within 2.0–4.6 and 6.8–15.4 μg mL−1, respectively. Validation showed that this simple MEEKC had feasible accuracy and precision. The developed method also successfully quantified seven CQA isomers in 13 solid (tablet, capsule, and granula) and liquid (injection and oral liquid) pharmaceutical preparations of honeysuckle.

    ABSTRACT: The interaction of letrozole, an efficient and safe aromatase inhibitor, with herring sperm DNA (hsDNA) was investigated in vitro through spectroscopy analysis and molecular modeling to elucidate the binding mechanism of anticancer drugs and DNA. The binding constant and the number of binding sites were 2.13 × 10(4) M(-1) and 1.09, respectively, at 298 K. Thermodynamic parameters (ΔG, ΔH and ΔS) exhibited negative values, which indicated that binding was spontaneous and Van der Waals forces and hydrogen bond were the main interaction forces. Fourier transform infrared spectroscopy and other spectroscopy analysis methods illustrated that letrozole could intercalate into the phosphate backbone of hsDNA and interact with the nitrogenous bases. Consistent with the experimental findings, molecular modeling results demonstrated that the interaction was dominated by intercalation and hydrogen bonding. Copyright © 2015 John Wiley & Sons, Ltd.
