3D Rapid Prototyping technology is the technology using a process of increasing the material layer by layer to form three-dimensional solid model via RP processing equipment produced. Therefore, before rapid prototyping, geometry data should be obtained first from the CAD system, reverse engineering, CT, etc. Then pretreat the data that matching with 3D rapid prototyping layered software and output to the corresponding 3D rapid prototyping system, and then to complete the 3D printing.

As a global famous brand specializing in sports products business, NIKE is on a road to conduct continuing innovation and upgrade on the basis of environment footprint valuation of whole value chain when seeking business sustainable development. This paper introduces the standard and content of NIKE's environment footprint valuation and analyses the valuation results in order to provide ideas for domestic enterprises. The paper summarizes meanwhile that the integrated management of the whole value chain, technical innovation, low-carbon-oriented design and "close loop" waste management are what the domestic enterprises can learn from NIKE.

New forms of extracurricular programs on creativity in primary schools are bound to emerge in the near future due to the popularization of 3D printing technology. This paper acknowledges the current situation of development of the extracurricular creative programs in China's primary schools, underlining the importance to introduce 3D printing and rapid prototyping technologies in the extracurricular activities. To sustain this argument, the activities of several creative 3D printing courses will be explained and discussed in the paper. Moreover, it will be shown how the particularity of the courses came from the combination of 3D printing technologies with culinary arts, bringing together traditional recipes with immersive and unexpected culinary experiences. The paper is divided in three parts. In the first part the state of the art of the extracurricular activities in primary schools in China will be shown. The second part will introduce the educational action research as the main methodological framework used in the teaching activities. In the third part the examples will be presented emphasizing on the importance and advantages of experiential learning. The conclusion will present the level of satisfaction of the students, and the benefits of introducing rapid prototyping technologies in the primary schools. © 2017 Association for Computing Machinery.

With the rapid growth of China's economy and population and the rapid increase in consumption number of textile and apparel, the research on the recycling and reuse of the old clothing has become more and more valuable. The paper constructed the recycling system of waste and old clothing from collection, sorting and recycling etc. It is pointed out that the old clothes recycling usually contain several forms such as: recycling bins, recycling activities and to university or corporate recovery, sorting clothes will usually clothing sorting for donations, export, and fibrosis and several other conditions, and the old clothes reuse usually includes donations, exports to Africa, physical reuse, fibrosis and manufacturing industrial materials etc.

Social enterprises mainly aim at achieving their social objectives, by adopting commercialized operation to make a profit, and then using the profit to invest in their social goals or communities, rather than returning to shareholders or owners. In order to study the operation of the existing social enterprises in China, the author investigated business methods of collecting, sorting and selling used clothing taken by Tongxinhuhui charity shop. Within 10 years, Tongxinhuhui provided dozens of migrant workers, the vulnerable groups, stable employment, and saved migrant workers tens of millions of living costs by tapping community resources. Its profits were used to support migrant education and other related activities, so as to improve the living conditions of migrant groups. Tongxinhuhui created social benefits, at the same time, turned a profit, which demonstrates sustainability of its operations, transparency is necessary guarantee for its continuing operations.

In order to design and weave regenerated wool blended fabrics and to test their performance, firstly 9 types of regenerated wool blended fabrics were designed and weaved in jacquard weave and plain weave and weft backed weave, which are made of 4 types of 80% regenerated wool and 20% nylon yarns and of 3 types of 100% wool yarns. Then breaking force, pilling resistance, wrinkle recovery, stiffness and flexibility, antistatic property of fabrics were tested and analyzed. Results showed that the breaking force of regenerated blended wool yarn was less and regenerated blended wool yarn was suitable for using as weft threads, and the pilling resistance of regenerated blended wool fabrics was poorer but it was increased by choosing the rational fabric texture construction and interweaving with other yarns. The research results can provide a certain reference for application of regenerated wool and for design & development of regenerated wool fabrics.

A capacitive deionization (CDI) cell was built with electrodes made of an inexpensive commercial activated carbon fiber (ACF), and then modified by incorporating ion-exchangers into the cell compartment. Three modified CDI designs were tested: MCDI - a CDI with electrodes covered by ion-exchange membranes (IEMs) of the same polarity, FCDI - a CDI with electrodes covered by ion-exchange felts (IEFs), and R-MCDI - an MCDI with cell chamber packed with ion-exchange resin (IER) granules. The cell was operated in the batch reactor mode with an initial salt concentration of 1000 mg/L NaCl, a typical level of domestic wastewater. The desalination tests involved investigations of two consecutive operation stages of CDIs: electrical adsorption (at an applied voltage of 1.2 V) and desorption [including short circuit (SC) desorption and discharge (DC) desorption]. The R-MCDI showed the highest electric adsorption as measured in the present study by desalination rate [670 ± 20 mg/(L h)] and salt removal efficiency (90 ± 1%) at 60 min, followed by the MCDI [440 ± 15 mg/(L h) and 60 ± 2%, respectively]. The superior desalination performance of the R-MCDI over other designs was also affirmed by its highest charge efficiency (110 ± 7%) and fastest desorption rates at both the SC [1960 ± 15 mg/(L·h)] and DC [3000 ± 20 mg/(L·h)] modes. The desalination rate and salt removal efficiency of the R-MCDI increased from ~270 mg/(L h) and 83% to ~650 mg/(L h) and 98% respectively when the applied voltage increased from 0.6 V to 1.4 V, while decreased slightly when lowering the salt water flow rate that fed into the cell. The packing of IER granules in the R-MCDI provided additional surface area for ions transfer; meanwhile, according to the results of electrochemical impedance spectroscopy (EIS) analysis, it substantially lower down the R-MCDI's ohmic resistance, resulting in improved desalination performance. © 2013 Elsevier Ltd.

Ultrafine fullerene (C60)/poly(N-vinylcarbazole) (PVK) composite fibers with 1 μm diameter were prepared by electrospinning C60/PVK blend solutions in solvent mixtures of N,N-dimethylformamide (DMF)/toluene. The UV absorption spectra of nanofibers have a similar behavior as observed in the thin films for the same doping condition. It is interesting to observe that the PVK nanofibers have a very strong blue-violet luminescence, while 'bright spots' due to C60 can be observed on the C60/PVK fibers under UV irradiation in a fluorescence optical microscope. Compared to the emission spectra of PVK thin films, the photoluminescence of the PVK nanofibers shows a new emission peak at 437 nm. Efficient energy transfer was observed in C60/PVK thin films, as well as in blend nanofibers. © 2009 Elsevier B.V. All rights reserved.
