    Description: Byline: Xin Wang, Jintu Fan Keywords: coatings; textiles; thermal properties ABSTRACT In this article, we report on an experimental investigation of the thermal insulation and moisture vapor resistance of a thermal insulation assembly consisting of polyester battings and metal-coated thin nonwoven interlayers. Because of the blocking of radiation by the coated metal nanoparticles, the thermal radiative conductivity of the interlayer decreased from 0.0249 to 0.0194 W/m K after coating. We found that the thermal insulation of the fibrous assembly could be greatly improved without any significant effect on the moisture transfer through the incorporation of metal-coated interlayers between the fibrous battings in appropriate patterns. The thermal resistance of the assembly increased gradually with increasing number of incorporated interlayers until it reached a plateau. The presence of more metal-coated interlayers closer to the hot (heat-source) side was beneficial to higher thermal insulation. The moisture vapor resistance of the assembly showed no significant changes with increasing number of interlayers. The incorporation of three interlayers showed the best thermal insulation properties with little effect on the moisture transmission. This kind of thermal insulation assembly will have significant advantages in cold-protective clothing because of its high insulation properties and breathability. [c] 2013 Wiley Periodicals, Inc. J.

    Description: A transparent and comprehensive statistical system in China would provide an important basis for enabling a better understanding of the country. This paper focuses on energy intensity (EI), which is one of the most important indicators of China. It firstly reviews China's GDP and energy statistics, showing that China has made great improvements in recent years. The means by which EI data are released and adjusted are then explained. It shows that EI data releases do not provide complete data for calculating EI and constant GDP, which may reduce policy transparency and comprehensiveness. This paper then conducts an EI calculation method that is based on official sources and that respects the data availability of different data release times. It finds that, in general, China's EI statistics can be considered as reliable because most of the results generated by author's calculations match the figures in the official releases. However, two data biases were identified, which may necessitate supplementary information on related constant GDP values used in the official calculation of EI data. The paper concludes by proposing short- and long-term measures for improving EI statistics to provide a transparent and comprehensive EI indicator. Highlights ► This paper examines data release and adjustment process of energy intensity (EI) target of China. ► New insights on the comprehensiveness and transparency of EI data. ► Potential data bias between author's calculation and official data due to lack of constant GDP data. ► Proposition for improving short- and long-term EI statistical works.

    Description: In order to improve profitability, freight forwarding companies try to organize their operational transportation planning systematically, considering not only their own fleet but also external resources. Such external resources include vehicles from closely related subcontractors in vertical cooperations, autonomous common carriers on the transportation market, and cooperating partners in horizontal coalitions. In this paper, the transportation planning process of forwarders is studied and the benefit of including external resources is analyzed. By introducing subcontracting, the conventional routing of own vehicles is extended to an integrated operational transportation planning, which simultaneously constructs fulfillment plans with overall lowest costs using the own fleet and subcontractors’ vehicles. This is then combined with planning strategies, which intend to increase the profitability by exchanging requests among members in horizontal coalitions. Computational results show considerable cost reductions using the proposed planning approach.

    Description: To link to full-text access for this article, visit this link: http://dx.doi.org/10.1016/j.actamat.2012.07.058 Byline: Xin Wang (a), Changjiang Wang (b), Alan Atkinson (a) Keywords: Thermal barrier coating (TBC); Interface toughness; Cross-sectional indentation (CSI); Residual stress; Finite-element modelling (FEM) Abstract: The interface fracture toughness of thermal barrier coatings (TBCs) on high-pressure turbine blades manufactured by electron beam physical vapour deposition was measured by a cross-sectional indentation (CSI) method. Scanning electron microscopy and luminescence mapping were employed to reveal that coating delamination induced by CSI was predominantly along the thermally grown oxide-bond coat interface and the shape of the delaminated area was approximately semicircular. The critical energy release rate (G.sub.c) for delamination was calculated based on a clamped circular plate model. Analysis of the stored energy release revealed that the residual stresses in the coating do not contribute to the total energy release rate provided that the delaminated area of the coating does not buckle. Therefore, for this method, detailed information of residual stresses is not necessary for the determination of interface fracture toughness. However, intercolumnar microfracture and shear displacement in the YSZ top coat can lead to significant overestimation of the interface fracture toughness in some situations. A method of specimen preparation is described to inhibit these effects. The interface fracture resistance of the TBCs was found to be 29[+ or -]9Jm.sup.-2 after between 35 and 100 thermal cycles (from room temperature to 1150[degrees]C with 1h duration).

However, the concentration responses of toxins had not been investigated in detail. Using formaldehyde as a toxic substance, the current responses were analyzed over a concentration range from 0.01% to 0.10% in a single chambered BES with 0mV (versus saturated calomel electrode) applied on the anode. The decay percentages of currents increased in proportion with the concentration of formaldehyde after 10000s ([approximately equal to]2.8h), with the peak R.sup.2 of 0.9361 observed at 35,000s ([approximately equal to]9.7h). Fitting results of exponential decay equation showed that the magnification factor (a) closely related with baseline currents and the toxicity factor (b) was in direct proportion to formaldehyde concentration (from 0% to 0.08%) except over the high concentration of 0.10%. These results provide preliminary information about toxin concentration responses in BESs.

    Description: Boronic acid-rich chitosan-poly( -3-acrylamidophenylboronic acid) nanoparticles (CS-PAPBA NPs) with the tunable size were successfully prepared by polymerizing -3-acrylamidophenylboronic acid in the presence of chitosan in an aqueous solution. The CS-PAPBA NPs were then functionalized by a tumor-penetrating peptide iRGD and loading doxorubicin (DOX). The interaction between boronic acid groups of hydrophobic PAPBA and the amino groups of hydrophilic chitosan inside the nanoparticles was examined by solid-state NMR measurement. The size and morphology of nanoparticles were characterized by dynamic light scattering and electron microscopy. The cellular uptake, tumor penetration, biodistribution and antitumor activity of the nanoparticles were evaluated by using three-dimensional (3-D) multicellular spheroids (MCs) as the model and H22 tumor-bearing mice as the model. It was found that the iRGD-conjugated nanoparticles significantly improved the efficiency of DOX penetration in MCs, compared with free DOX and non-conjugated nanoparticles, resulting in the efficient cell killing in the MCs. antitumor activity examination indicated that iRGD-conjugated CS-PAPBA nanoparticles promoted the accumulation of nanoparticles in tumor tissue and enhanced their penetration in tumor areas, both of which improved the efficiency of DOX-loaded nanoparticles in restraining tumor growth and prolonging the life time of H22 tumor-bearing mice.
