Ultra-Stretchable Monofilament Flexible Sensor with Low Hysteresis and Linearity based on MWCNTs/Ecoflex Composite Materials

Wearable human–computer interaction equipment is a common technology, which can improve the comfort, convenience, and safety of the human body, and also can monitor human health. The flexible and wearable tensile sensor can be conveniently installed on clothes or directly connected to the body. This provides a convenient, timely, and portable solution for the detection of human motion. Therefore, wearable electronic equipment is gaining more attention. In this paper, a highly stretchable, flexible, and sensitive strain sensor which is based on multi-walled carbon nanotubes/Ecoflex nanocomposites is reported. A monofilament tensile sensor obtains good linearity (10.77%), low hysteresis (1.63%), good stability (6000 cycles under 100% strain), and ultra-high strain range (ε = 1300%). This ultra-stretchable sensor has potential applications in human motion monitoring, medical rehabilitation, health monitoring, human–computer interaction, and soft robots.

重组人EC-SOD包涵体的稀释复性及重折叠后蛋白的纯化

目的确定重组人ECSOD包涵体体外稀释复性和复性后蛋白纯化的适宜方法。方法通过对pH、温度、包涵体蛋白浓度、尿素和精氨酸浓度及氧化还原对比率的定性定量分析,研究重组人ECSOD包涵体体外稀释复性的基本条件。采用金属离子亲和柱(IMAC)和肝素亲和柱(Heparinsepharose)对复性蛋白进行纯化,比较纯化效率的差异。结果最佳复性条件为pH8.5,尿素浓度为1.5molL,精氨酸浓度大于0.3molL,GSH∶GSSG=4∶1;复性温度及包涵体蛋白终浓度越高,复性效率越低。IMAC和Heparinsepharose亲和柱均可用来纯化复性蛋白溶液,但Heparinsepharose纯化效率较高。结论确定了重组人ECSOD包涵体体外稀释复性的最佳条件及复性后蛋白纯化的方法。     

Theoretical Models for Binder Burnout

The kinetics of binder burnout, from a ceramic green body, are considered for the case of an "unzipping" binder which decomposes to produce a volatile monomer. The process is considered to fail if the concentration of monomer in the green body exceeds that in equilibrium with vapor at 1 atm (≅10⁵ Pa), when an internal bubble would be expected to form. Steady-state diffusional calculations and computer simulations explore the size and temperature dependence of the process and are in agreement. The model suggests that it is not feasible to burn out a large flat piece greater than about 3 mm thick, without going to very long times of burnout. The kinetics are significantly improved if porosity develops in the piece during the early stages of decomposition, as opposed to the retreat of the binder into the piece on a uniform front.
