  • Transfer and mechanical behavior of three-dimensional honeycomb fabric

    Xiao, X.   Hua, T.   Wang, J.   Li, L.   Au, W.  

    Honeycomb woven fabric is a single layer of fabric exhibiting three-dimensional (3D) cellular shape on both fabric sides due to the combination of periodic straight yarn floats and partial plain weave. In a fabric weave repeat, the triangle shape of increased yarn floats and crossed diagonal woven lines form two inverted pyramidal spaces on the fabric surfaces and a closed internal space. This particular 3D architecture is bound to influence the fabric transfer and mechanical properties. This study investigated these properties for honeycomb weaves experimentally, including air resistance, thermal conductivity, water absorption and vapor transmission rate, bending rigidity, compressional energy and tensile behavior. The typical two-dimensional plain woven fabrics with the same yarns and density were set as references and elastic yarns were considered as a factor of effect on the fabric properties. The measurements by the Kawabata Evaluation System and Instron machine show that the honeycomb woven fabric has enhanced air permeability and water absorption, as well as lower thermal conductivity compared to that of the plain woven fabric. Higher bending rigidity, compressional energy and Young’s modulus are also observed for honeycomb fabrics. The mechanical properties are found to be affected significantly by applying the elastic yarns to the honeycomb woven fabrics.

  • Estrogen in the Anterior Cingulate Cortex Contributes to Pain-Related Aversion

    Xiao, X.   Yang, Y.   Zhang, Y.   Zhang, X.-M.   Zhao, Z.-Q.   Zhang, Y.-Q.  

    The rostral anterior cingulate cortex (rACC) is a key structure of pain affect. Whether and how estrogen in the rACC regulates pain-related negative emotion remains unclear. Behaviorally, using formalin-induced conditioned place aversion (F-CPA) in rats, which is believed to reflect the pain-related negative emotion, we found that estrogen receptor (ER) inhibitor ICI 182, 780 (ICI, 7,17-[9-[(4,4,5,5,5-Pentafluoropentyl)sulfinyl]nonyl]estra-1,3,5(10)-triene-3,17-diol) or inhibitor of aromatase androstatrienedione into the rACC completely blocked F-CPA in either sex. An analogous effect was also observed in ovariectomy rats. Furthermore, exogenous estrogen in the absence of a formalin noxious stimulus was sufficient to elicit CPA (E-CPA) in both sexes by activating the membrane estrogen receptors (mERs) and N-methyl-D-aspartic acid (NMDA) receptors (NMDARs). Electrophysiologically, we demonstrated that estrogen acutely enhanced the glutamatergic excitatory postsynaptic currents (EPSCs) in rACC slices by increasing the ratio of NMDAEPSCs to -amino-3-(5-methyl-3-oxo-1,2- oxazol-4-yl) propanoic acid EPSCs and presynaptic glutamate release. Interestingly, a brief exposure to estrogen elicited a persistent enhancement of NMDAEPSCs, and this NMDAlong-term potentiation required the activation of the mERs, protein kinase A and NMDAR subunit NR2B. Finally, estrogen induced rapid dendritic spine formation in cultured rACC neurons. These results suggest that estrogen in the rACC, as a neuromodulator, drives affective pain via facilitating NMDA receptor-mediated synaptic transmission.

  • Through-thickness air permeability of woven fabric under low pressure compression

    Xiao, X.   Hu, J.   Hua, T.   Zeng, X.   Long, A.  

    Through-thickness permeability (TTP) is one primary property of technical textiles used in air-related applications, such as filtration and protection. The TTP depends on the textile geometrical factors and usually varies according to the test conditions. In this article, the effect of low air pressure compression (LPC) on TTP of woven fabric was investigated. Nine woven fabrics were measured for the relationships of LPC and thickness, LPC and fabric in-plane dimensions, air pressure drop (APD) and air velocity, as well as LPC and fabric TTP. A dramatic decrease of woven fabric thickness was found below the APD value of 200 Pa and less decreased thickness was observed with a continued increase of APD. The variation of fabric in-planar dimensions was found to be negligible during LPC. The plot relationship of the APD and measured air velocity was presented in linearity for most fabric samples. The fabric TTP showed a linear proportion to the fabric thickness, indicating the fabric to be more permeable with the increase of thickness. A sensitivity study showed an evident difference between using fabric constant and decreased (LPC) thickness in calculating TTP, disclosing the importance of compression in fabric TTP evaluation.

  • The taste-visual cross-modal Stroop effect: An event-related brain potential study

    Xiao, X.   Dupuis-Roy, N.   Yang, X.L.   Qiu, J.F.   Zhang, Q.L.  

    Event-related potentials (ERPs) were recorded to explore, for the first time, the electrophysiological correlates of the taste-visual cross-modal Stroop effect. Eighteen healthy participants were presented with a taste stimulus and a food image, and asked to categorize the image as "sweet" or "sour" by pressing the relevant button as quickly as possible. Accurate categorization of the image was faster when it was presented with a congruent taste stimulus (e. g., sour taste/image of lemon) than with an incongruent one (e. g., sour taste/image of ice cream). ERP analyses revealed a negative difference component (ND430-620) between 430 and 620 ms in the taste-visual cross-modal Stroop interference. Dipole source analysis of the difference wave (incongruent minus congruent) indicated that two generators localized in the prefrontal cortex and the parahippocampal gyrus contributed to this taste-visual cross-modal Stroop effect. This result suggests that the prefrontal cortex is associated with the process of conflict control in the taste-visual cross-modal Stroop effect. Also, we speculate that the parahippocampal gyrus is associated with the process of discordant information in the taste-visual cross-modal Stroop effect. (C) 2014 IBRO. Published by Elsevier Ltd.

  • Cryogenic Adsorption of Hydrogen Isotopes over Nano-Structured Materials

    Xiao, X.   Heung, L. K.  

    Porous materials such as zeolites, activated carbon, silica gels, alumina and a number of industrial catalysts are compared and ranked for hydrogen and deuterium adsorption at liquid nitrogen temperature. All samples show higher D(2) adsorption than that of H(2), in which HY zeolite has the greatest isotopic effect while 13X zeolite has the highest hydrogen uptake capacity. Material's moisture content has significant impact to its hydrogen uptake. A material without adequate drying could result in complete loss of its adsorption capacity. Even though some materials present higher H(2) adsorption capacity at full pressure, their adsorption at low vapor pressure may not be as good as others. Adsorption capacity in a dynamic system is much less than in a static system, as expected. The same type of material from different vendors or lots may behave differently.
